Incline Belt Conveyors vs. Bucket Elevators

Both incline belt conveyors and bucket elevators help food producers maximize their production, efficiency, and footprint by elevating their products within a processing line. These machines share benefits such as optimal product handling, flexible configurations, easy integration, and sanitary design. Though incline belt conveyors and bucket elevators serve a similar purpose, these machines have numerous differences. This article will discuss what makes each machine unique and provide insight into which machine would be more effective for various applications. This article will cover:




Incline belt conveyors are driven by a pulley, belt, and drive lugs. In effect, an inclined belt moves continuously, transporting materials along the conveying path.


The four primary components of an incline belt conveyor are a conveyor belt, rollers, drive system, and head and tail pulleys.

  • Conveyor Belt: A continuous loop of material that rotates around two or more pulleys.
  • Rollers: Support the conveyor belt and allow it to move smoothly.
  • Drive System: A motor, gearbox, and pulleys drive the conveyor belt.
  • Head and Tail Pulleys: Redirect the conveyor belt and maintain tension.



The three fundamental steps in an incline belt conveyor’s operation are as follows:

  1. Loading: Material is placed on the conveyor belt at the loading point.
  2. Inclined Transport: The conveyor belt moves the material on an incline.
  3. Discharge: Material is unloaded from the conveyor belt at the desired location.


The top three benefits of incline belt conveyors are as follows:

  • Reliable operation with simple washdowns and maintenance
  • More sanitary design with fewer moving parts and open-frame construction
  • More flexible designs with multiple shapes and belt options


Unlike an incline belt conveyor, a bucket elevator is driven by a chain and sprocket. Its buckets are attached to the chain and move vertically to elevate bulk materials.


The four primary components of a bucket elevator are buckets, a chain, a drive system, and head and tail pulleys.

  • Buckets: Attached to a chain, the buckets transport the materials.
  • Chain: Driven by a motor, the chain facilitates the vertical movement of the buckets.
  • Drive System: A motor and gearbox provide the necessary power for vertical lifting.
  • Head and Tail Pulleys: Guide the chain, changing the direction of material flow.


The three fundamental steps in a bucket elevator’s operation are as follows:

  1. Loading: Material is fed into the buckets at the bottom of the elevator.
  2. Vertical Transport: The buckets move vertically, lifting the material to the desired height.
  3. Discharge: At the top, the buckets tip over, and the material is discharged into one or multiple discharge points.


The top three benefits of bucket elevators are as follows:

  • 90-degree elevation in a small footprint
  • Large processing volume
  • Gentle handling of dry and wrapped bulk products eliminates degradation, yield loss, and breakage


As discussed above, though these two machines serve a similar purpose, they differ in how they operate and how they handle materials. The table below summarizes the similarities and differences between the two machines.

A primary advantage of incline belt conveyors is that they are easier to clean. A smoother surface and more open frame provide easier access for cleaning and fewer places for bacteria to build up and hide. This makes them the ideal conveyance solution for raw or sticky products, bakery products like cookies or bars, and fruits and vegetables. If the product you need to convey requires a full washdown sanitation, we recommend an incline belt conveyor.

As compared to bucket elevators, incline belt conveyors require less maintenance. This allows you to spend less time training employees on maintaining the machine and less money on labor and other maintenance costs. If you have a smaller or less experienced staff, an incline belt conveyor may allow you to more effectively use your resources by saving time and money on machine maintenance.

Another benefit of choosing an incline belt conveyor is the additional customization opportunities. Although both machines can be custom-configured for your application and facility requirements, incline belt conveyors are a bit easier to customize. If your process and/or application constantly evolves, an incline belt conveyor may allow you to be more nimble and update the necessary machine features as your application changes.


A significant advantage of bucket elevators is that they allow for more space savings in your facility. By elevating your products vertically at no angle, a bucket elevator is the easy choice if you have horizontal space restrictions in your building’s layout. Also worth noting is that the maximum width of a bucket elevator is 48” while an Incline Belt Conveyor can be as wide as 72”, allowing for a smaller footprint.

Bucket elevators are the ideal solution for producers of bulk-wrapped or dry foods such as nuts, candy, pet food, pasta, rice, and cereal. These products need gentle handling to avoid breakage and degradation, move in large volumes, and often have fewer sanitary requirements.

A bucket elevator is also the preferred option for food producers with significantly high throughput requirements. For example, an 18” wide Incline Belt Conveyor at a 90° angle has a throughput capacity of 0.2 Cu/FT, while an 18” wide bucket elevator has a throughput capacity of up to 0.525 Cu/FT; in this example, a bucket elevator has over double the throughput capacity as compared to an incline belt conveyor of equal proportions.

Another notable advantage of bucket elevators is that they can be customized to have several discharge points on the same unit. This allows food producers to keep their products flowing into several different processes from a single machine, providing a more streamlined operation.


Two additional considerations regarding these machines are their total cost of ownership and machine lifespan. For the same application, the initial prices of these machines are very similar, with Incline Belt Conveyors, on average, being slightly more expensive. As for machine lifespan, bucket elevators tend to last much longer if properly maintained. Though they require a bit more maintenance, they can operate successfully longer.

Bucket Elevator Capacity for Various Sizes & Applications

There are many ways to lift food products, but bucket elevators remain a processing industry stalwart for one reason: an unmatched ability to meet producers where they are with simple, robust lifting capacity rightsized to their product, process, and pocketbook.


Whether you’re an artisan kitchen on the up or a global household name, bucket elevators provide safe, efficient lifting that respects your product, reduces waste, and delivers the throughput you need at a price you can afford.

Here, we take a look at the technology behind bucket elevators and specifically why they are so good at matching efficient lifting capacities to different levels of demand. Along the way, we’ll also look at the best applications for bucket elevators and calculate the bucket elevator design capacity you will need. 


Bucket elevators enable you to raise bulk products to elevated platforms and mezzanines using an “endless” series of overlapping containers or buckets on a vertically mounted chain loop system. It’s a simple design that comes with some big benefits.

Big Reach, Small Feet

Unlike almost any other lifting technology, bucket elevators can raise product to almost any practical height, and do this within a very small shop floor footprint. As height increases, there is also little or no increase in an elevator’s required footprint.

That makes bucket elevators an efficient and cost-effective way to add space and functionality to your facility, especially for drop-down applications like mix/blend systems, scales, and packaging that require additional height.

Straight Up Versatility

Bucket elevators also work pretty much the same, no matter how big or small they are. Their tried-and-true technology is also relatively easy to customize for your system’s specific needs.

That makes integration with other line equipment simpler. Experienced equipment providers like PFI can design horizontal, C, S, or Z-shaped elevators capable of accepting and distributing products in almost any configuration and with multiple discharge options for maximum flexibility.

Good bucket elevator equipment is also famously durable. With regular maintenance, some PFI conveyors are still running after upwards of 60 years on the job. 

Strong but Gentle

Bucket elevators’ overlapping containers are designed primarily to lift dry bulk loose products while minimizing loss through spillage or degradation. V-shaped buckets minimize sticking and entrapment. When sized correctly for the application, they also protect brittle or friable foods from breakage.

As a result, bucket elevators are preferred for lifting a huge range of foods, including:

PFI bucket elevator for pet food processing


There is also no doubt about bucket elevators’ appetite for work. Machines equipped with fundamentally the same technology move loads as small as 135 cubic feet per minute and as large as 3,780 cubic feet.

That strength and versatility means affordable, game-changing lifting capacity at the scale that matters to your business. It’s powerful but right-sized to your specific needs. 

Let’s take a closer look at how that works.

Calculating Bucket Elevator Capacity

Are you a bulk handler of raw staples like flour or rice, an added-value processor of cereals or mixed snacks, or a specialist in packaging delicate products like pasta or wrapped hard candy? 

Even if your overall production capacities are the same, your throughput requirements in each case will be very different. 

Here’s how to calculate bucket elevator capacity to meet your needs. There are several factors to be considered: 

  1. Bucket Capacity: The overall volume of each bucket on your system in cubic feet is calculated from bucket width and depth.
  2. Bucket Spacing: The spacing between buckets on the elevator chain overlap which helps to avoid spillage.
  3. Chain Speed: The speed at which your elevator chain moves in feet per minute, depending on the strength of your system’s motors, the weight of your product, and how delicate it is. 

From these measurements, elevator capacity can be calculated using this simple formula:

Capacity = Bucket Capacity x Bucket Spacing x Belt Speed

The result is the cubic feet per minute delivered by your elevator system. For example, for a system with buckets each holding two cubic feet of product spaced at one-foot intervals along a chain moving at 30 feet per minute, the overall capacity of the conveyor would be 60cfm.

Rightsizing Capacity

Every producer varies, of course, by the differing amounts of product that would fit into a given volume without excessive degradation or loss and by the number and weight of buckets that a system of a given power could safely handle. 

The beauty of bucket elevators’ time-tested design and flexibility is the ability to customize almost any factor affecting its capacity to meet your needs, including the size and capacity of individual buckets, the number of buckets on a chain, and the speed of the chain itself. 

And, with over 60 years of experience supplying vertical handling solutions worldwide, PFI knows how to deliver bucket elevator solutions built for maximum capacity at any scale.

Low, Medium, and High-Capacity Options

We deliver bucket elevators in low, medium, and high-capacity models. The elevator’s size determines the buckets’ width, which in turn, determines capacity. Height and speed also dictate capacity as do the food product’s weight and size. 

Buckets are available in nine different capacities based on widths of 6, 9, 12, 15, 18, 24, 30, 36, and 48-inch widths to fit different frames, products, and application needs. 

PFI designs stainless steel bucket elevator frames tailored to your bucket width, lift, and integration specifications. Where sanitary needs are highest, our frames include IP69K-compliant closed-casing tubing for maximum contamination protection. 

Where needed, bucket elevator units can also be equipped with:

  • Positive motion controls for smooth, rapid bucket movement to protect your product 
  • Sanitary clean-in-place (CIP) systems to maintain hygiene during operation
  • Waste-reducing slide-out catch pans

More Bucket Options

PFI matches our equipment to your unique processing needs in other ways too. Our highly customizable buckets are designed to maximize both capacity and performance. 

For example, most applications prefer our trusted standard v-shaped bucket shape for efficient emptying with minimal sticking and entrapment. However, we also offer:

  • Optional ribbed surface texture for stickier foods
  • Stainless steel, polycarbonate, and polyethylene to meet your specific sanitary, cleaning, and durability needs
  • A wide choice of colored plastics
  • Metal-detectable plastics for improved food safety

Up-Front Affordability, Long-Term Value

Bucket elevators’ scalable, flexible technology delivers hard-to-match performance at an unbeatable entry point. You’ll get the lifting power you need today to deliver on customer expectations or take your growing business up a notch.

In addition, few industrial solutions can match bucket elevators’ track record of reliability and long-term return on investment. When you invest in high-quality bucket elevator technology, you’re adding value to your operation by ensuring: 

  • Durability: Premium quality equipment from a reputable supplier can deliver decades of trouble-free service.
  • Low maintenance: Simple technology, quality construction, and readily available parts keep long-term operating costs low.
  • Low wastage: Properly designed and calibrated equipment minimizes food wastage over your equipment’s long life.

Flexible, affordable, and durable, bucket elevators offer the performance you need to aim higher and the long-term value you’ll need down the line.

The food industry is changing and there is more than one way to effectively lift dry or loose bulk foods up a level. So why stick with a “legacy” technology like bucket elevators?

Bucket elevators may not be ideal for every food product lifting application. The type of food you handle is important, as is connecting equipment and the layout of your facility. However, they make a lot of sense when you need a reliable, durable, and compact way to lift loads of almost any size.

In particular, bucket elevators’ tried-and-true design, scalability, and versatility can be a good fit for processors who: 

  • Handle very small or very large loads
  • Process dry bulk foods, packaged goods, fresh produce, or frozen products
  • Handle delicate, brittle, or friable foods
  • Have limited space to add new equipment to the facility

To get the most out of your bucket elevator solution, it’s essential to invest in high-quality equipment that is optimized for your application. That’s why it’s critical to partner with an experienced, reliable food-handling partner like PFI, who can advise you on the ideal solution.

How to Choose The Right Food-Grade Conveyor System

As a food processor, you’ve built (or are building) a plant full of specialized machinery designed to prepare your product exactly how you want it. 

Protect your investment by selecting a food conveyor system that maintains the quality and safety of your product.

Choosing low-cost or generic conveyor machinery may allow you to hit your productivity targets while keeping your project investment low.

However, damaged or poorly processed products and mounting maintenance bills will cost you more in the long run.

Worse, potential hygiene and food safety issues from using poorly designed or inappropriate equipment can cost your business millions and permanently damage your brand reputation.

Here, we look at how to choose safe, efficient food-grade conveyors that meet your company’s needs. We’ll lay out some key questions to consider as you work through the equipment procurement process and longer-term factors to remember.

We’ll also explain why partnering with an experienced, reputable food conveying solutions provider can help you get more value from your investment in conveying equipment.


It’s tempting to see food conveying equipment as an “add-on” investment that just moves your ingredients and product where it needs to be for processing and packaging.

Smart manufacturers know that money spent on quality conveyor systems can add real value to your operation by helping protect and even enhance the quality of your products and the efficiency of your process.

It all starts with making wise, up-front decisions about the equipment you need and where you choose to source it. If you’re in the market for food-grade conveyor systems, here are nine key questions to consider when choosing the best solution.

1. Is It Really a Sanitary Conveyor? 

Not all conveyors are designed specifically for handling foodstuffs. If you’re buying an off-the-shelf solution, be sure it is indeed a food-safe sanitary conveyor that can handle the elevated hygiene requirements that come with processing foods.

Look for conveyor designs that include:  

  • Materials that resist bacteria growth, like stainless steel and food-safe plastics 
  • Washdown-resistant materials and construction
  • Sloped surfaces to drain water and limit condensation build-up
  • Radiused corners and smooth, well-placed welds
  • Tight tolerances and smooth joins to limit bacteria harboring
  • Minimal food contact with fasteners, washers, or threads

If you’re handling foods that are particularly susceptible to bacterial contamination, like fresh meats or dairy, you’ll need to be sure that all food-contact surfaces on your conveyor are of stainless steel, and that its construction includes no hollow tubing that could harbor moisture.

A vibratory food conveyor system made of stainless steel trays keeps chicken tenders sanitary.

For these applications, it’s also best to look for conveyors that meet the IP69K standard that ensures maximum water-tightness to better resist repeated high-temperature washdown and sanitation procedures. 

2. Does It Meet (and Exceed) Food Safety Regulations?

In reality, whether a conveyor is suitable for handling food is not just up to you. If you’re considering buying a new or used conveyor, be sure to ask for proof that the equipment meets the minimum regulatory food safety and hygiene requirements for your application.

Depending on the planned application, true sanitary conveyors must meet a range of regulatory and industry standards. These include benchmarks determined by:

What’s more, regulations have evolved and become consistently tighter over time. That’s why many leading food manufacturers only buy equipment from suppliers whose equipment already exceeds the existing regulations and industry benchmarks.

3. Which Conveyor Type Is Best for My Product?

Different conveyor types move products differently. Belt, bucket and incline conveyors, tote dumpers, horizontal motion, and vibratory conveyors are all designed to solve particular food handling problems. But which one is right for you?

A lot depends on the specific handling requirements of your food products at any point in your process. Some key questions to ask include:

  1. What are the sanitary requirements of my product at this point in my process? These change as raw foods are processed into cooked, packaged products.
  2. What are the handling characteristics of your food at this point? Are foodstuffs frozen, raw, or cooked? Solid or liquid? Fine or granular? Hot or cold? Oily, waxy, or sticky? Large, small, or irregularly shaped? Are they fragile or susceptible to bruising?
  3. Does your product require handling or processing while being conveyed? Do foodstuffs need to be cooled, heated, or frozen? Do they need to be dewatered or dried, graded, screened, or positioned? Do products need to be mixed at a set ratio?
  4. What are the physical constraints of this production zone? This might include the maximum space available, distance to the next line process, and necessary changes in height or direction.
  5. How will my conveying equipment integrate with other equipment? Custom modifications might be required to allow one or more OEM units to work together.

The answers to these questions will narrow your options. For example, raw and frozen meats and dairy products may require vibratory or horizontal motion conveyors with the highest level of sanitary protection, while packaging operations may require less. In addition:

  • Conventional belt conveyors are a versatile choice for many foods from grains and dry bulk ingredients to baked products, produce, and packaged goods. Belt conveyors are also the preferred choice for precise food placement for pick-and-place applications. 
  • Horizontal motion conveyors are not suitable for fine materials but are effective at moving frozen foods and hard, granular products like pasta. Their gentle, gliding motion also makes them the go-to choice for delicate or seasoned items like snacks or pastries.
  • Vibratory conveyors are effective for moving small or powdery products like nuts and grains and delicate items like chocolates. The controlled agitation of these machines is also good for dewatering, grading, screening, or mixing of foods while in transit.

Be aware, though, that the physical constraints of your process or plant may also affect which conveyor you choose. Belt, horizontal motion, and vibratory conveyors can raise and lower product within limits, but significant height changes will require a bucket elevator conveyor system. 

Belt and vibratory conveyors move foods at a steady rate and are preferred where foods need to be heated, cooled, dried, or frozen while in transit. Horizontal motion conveyors allow many food products to be visually inspected while moving through the final stages of production.

Horizontal motion and, to some extent, vibratory conveyors are constrained in the lengths individual machines can cover. It may take a series of several units to cover the same distance that a single belt conveyor could span.

With so many factors in play, it’s important to choose a reputable sanitary equipment supplier offering the full range of conveying options. Only leading brand manufacturers have the experience and engineering expertise to:

4. Will My Conveyor Deliver the Throughput and Capacity I Need?

With all of the details in place, it’s time to assess whether the technology, customizations, and integrations you have put in place are going to deliver the daily throughput and overall line capacity you need.

Some conveyors are available in wider belt or pan configurations to boost capacity, while variable speed equipment (such as many horizontal motion models) allows you to fine-tune throughput according to your changing needs.

Better integration with existing equipment will normally also help boost overall line capacity. That said, if a given piece of equipment is not able to deliver the raw capacity you need on your line, you may need to reconsider your options.

5. What About Customization Options?

Different customization options can allow conveyors to be used for dramatically different applications. 

Adding non-stick pans to horizontal motion conveyors allows them to be used to handle greasy or sticky foods in the final stages of processing while using specially designed screens on vibratory conveyors allows them to be used to drain dipped or fried foods.

There’s no substitute for experience in understanding how different types of foodstuffs act when handled in bulk. That’s why it’s best to work with a food conveyor equipment specialist to identify the best mix of technology and customization for your operation.

6. Will It Fit My Plant Configuration?

The preferred handling technology for your product must be balanced against the realities of your plant and line setup. 

For example, bucket elevators or incline belt conveyors are the go-to solution when a product must be moved up or down more than just a few feet, while U-shaped curved conveyors are used to move around structures and equipment or add cooling loops into a line.

A bucket elevator conveyor system moves pet food in a vertical motion.

You might also need to plan for system support infrastructure like adjacent mezzanines and catwalks.

7. Will It Integrate With My Existing Equipment?

Additionally, your new conveying equipment must link as seamlessly as possible with your existing line equipment. Consider the speed and temperatures at which different pieces of equipment operate and the height and width of the entry and exit points to make sure they will align with your current system.

Also, consider whether your equipment will need to work with:

  • Customized infeed and discharge modifications 
  • Specialized safety requirements like vision, metal-detecting, and X-ray equipment
  • Process-specific options like clean-in-place systems, gates, or belt scrapers
  • Safety equipment such as emergency stops, cut-offs, and failsafes

Clearly, there is more to choosing a conveyor system than picking out a standalone piece of equipment. It’s essential to work with experts who can take a “whole plant” approach to help you plan how a conveyor will both meet and enhance your system integration.

8. How Much Will It Cost?

Finally, consider the upfront sticker price for a food-grade conveyor system. Is it within your project budget, and will the added capacity of your operation or the improved quality of your product justify the expense of purchasing, integrating, and commissioning the new equipment?


There is, however, more to choosing a food-grade conveyor system than upfront performance and cost. 

While the above questions will help ensure the conveyor system you choose meets your minimum requirements, it’s important to look at factors that affect the long-term value that food conveying equipment will bring to your company.

1. Durability

The lower price you might pay for generic or off-the-shelf conveying solutions might start to look expensive if you find yourself having to replace equipment within just a few years.

You’ll pay more upfront for a premium conveying solution customized to your specific needs, but you’ll also get more value for your money, including: 

  • More sanitary, longer-lasting materials 
  • Better equipment design, often with fewer moving parts
  • Conveyors designed to work with your product and process

This can mean a food-conveying system that delivers safety and efficiency for decades rather than just a few years, making your initial investment more valuable as time goes on.

2. Reliability

Higher quality equipment also runs better for longer, thereby boosting productivity and saving you money on downtime and maintenance. Leading brand equipment is designed to operate longer between services and to be easier to maintain

Consumable components and parts like belts, vibratory springs, and dumper cylinders are also easier to access and quicker to switch out on true professional-grade equipment—meaning your line is up and running sooner.

3. Safety & Sanitary

Quality food-grade conveyor systems are designed specifically for your application and process. This protects your staff from workplace accidents resulting from inappropriate handling techniques or poor integration with other equipment.

It also makes equipment easier to keep clean. Better-designed equipment is easier to strip down to wash and features fewer rough or exposed surfaces, such as bolt threads or panel joins. At the same time, this equipment has higher-quality welding, making surfaces easier to swab for food safety. 

Premium equipment also allows more regular maintenance to be performed without tools. This helps keep non-sanitary equipment off your line and reduces the likelihood of scratches or dents on food-exposed surfaces that could potentially harbor bacteria.

4. Value-Added Conveying

Food conveyors that are built with your process and application in mind also offer long-term value in other ways.

Integrated conveyor systems designed by a single supplier are easier to upgrade and expand as your business grows and develops. It’s easier to increase capacity and add functionality to equipment that comes from the same vendor.

It’s also possible to build more functionality into equipment that can be customized to your specific needs.

A food-grade conveyor sizes pieces of chewing gum.

For example, professional-grade vibratory conveyors can be designed to reorientate, spread, grade, and even separate materials on the go. They can even dewater washed products or allow cooked foods to cool while in motion, allowing you to reduce or even eliminate processing steps.

5. Vendor Experience

This value-added flexibility and functionality is only available, however, when you work with a professional food conveyor supplier capable of delivering solutions tailored to your needs. It also helps to partner with a company with extensive experience in the same food sector you work in. 

These dedicated suppliers offer extensive experience in best practices of food handling and processing you won’t find elsewhere, and the skills needed to put this knowledge to work.

In fact, across the food processing industry, while sector newcomers tend to look for the lowest price when sourcing conveying equipment, established players prefer to use equipment provided by one of just a few trusted suppliers.

6. After-Sales Service

There’s also a big difference in the levels of service provided by dedicated, established food conveyor equipment makers and more generic suppliers. For maximum return on your investment, look for a vendor that stands behind their equipment after the sale is completed. 

The best suppliers follow through on the work done to design and customize your equipment by ensuring the equipment is properly installed and your staff is fully trained.

Look also for companies that provide:

Of course, not all equipment providers have the scale and experience to provide this level of ongoing support. If you’re looking for a food conveyor partner for the long haul, make sure to find one that meets this criteria. 


If you’re a project manager overseeing a plant build-out or line upgrade, conveying equipment might be one of the last items on your list. But don’t let your food conveyor system become the weak link in your business’s value chain. 

Not only can skimping on the connections between your processes cost you more down the road, but you could be missing out on opportunities to add value to your operation by simplifying, streamlining, and combining steps into a single, seamlessly integrated whole.

Integrating Conveyors with Other Food Processing Equipment

Whether you’re building an all-new food processing facility or retrofitting an existing line, successfully integrating conveyor machines with OEM food processing equipment is a key piece of your project management puzzle.

A big part of the solution is understanding food processing conveyors not as individual pieces of equipment necessary for moving your product from one application to the next, but as a unified system that forms the backbone of your entire production process.

Well-designed and fully integrated conveyor systems should:

  • Allow food to move through your plant at a controlled, efficient rate
  • Ensure food reaches each process stage at the right speed and in the right quantities
  • Enable food processing units from different suppliers to work together

In addition, conveyor systems designed with your specific application in mind can add value to your entire production process by:

  • Managing bottlenecks, slowdowns, or outages 
  • Maintaining food quality and sanitary standards across your production process
  • Allowing food to be cooled, dried, sorted, or re-oriented in transit

Of course, all these benefits require seamless integration of your conveying equipment at every stage of your production process. 

Keep reading to learn what goes into integrating conveyor systems with other food processing equipment.


As a project manager for a food processing build or retrofit, it pays to start with integration front of mind as you plan your production flow and equipment purchases. 

Here are some key things to consider when you are evaluating conveying equipment for a particular handling or integration challenge.

1. Production Specifications

Let’s start with your “whole plant” approach to integration, whether you’re building a new line or retrofitting an existing one. What are your overall production goals, daily throughput, and volume requirements for your line? 

These should provide maximum and minimum parameters for selecting suitable conveying equipment.

2. Machine Specifications and Dimensions

Now let’s drill down to individual integration challenges. Note the input and output rates and volumes of the equipment a conveyor or series of conveyors will be connecting. Compare these to the capacities of the conveying equipment. 

Also consider the required infeed and discharge widths, heights, and lengths, as well as utilities like power, water, and ventilation. This will give you a shortlist of compatible conveyor equipment and an idea of any customized integration equipment that might be needed.

3. Zone-Specific Needs

Consider the specific requirements and constraints of the production area you are working in. These might include machine specifications, product make-up, and sanitary requirements, and the process stage, from receiving to final packaging.

For example, are there site-specific restrictions on the size or type of equipment that could be used? What is the state of the food at this point and how does that affect how it needs to be handled? Are there special sanitary requirements at this point?

4. Plant Specifications

Think about the plant’s needs. How can the equipment be integrated to benefit processes upstream and downstream? Do conveyors need to be supported from the floor, ceiling, mezzanine or existing structure? Can variable speed equipment be installed to prevent bottlenecks? Are additional structures like catwalks or platforms needed?

An incline to packaging conveyance system that also includes a vibratory conveyor to the scale.

5. Food Application

Now consider your product carefully. What are the needs of the food being handled and how will your integration solution affect its quality? Is it solid or liquid? Hot or cold? Sticky, slippery, fine, or granular? Is it large, small, or irregular in size? And, is it fragile or sensitive to bruising?

Does the state of the product change during handling? Does it need to solidify, dry, or cool? Does the product need to be graded, separated, or reorientated as it moves? If so, what additional equipment needs to be mounted on the conveyor to do this? 

Finally, what about applications that handle ingredients for multiple end products, or recipes that require different foodstuffs to be combined as they move?   

6. Worker Safety

Are there special considerations to ensure conveying equipment and integration solutions meet safety standards and do not endanger workers? Equipment must adhere to regulatory and industry standards to protect workers from burns, cuts, entrapment, and trip and fall hazards.

Customized integration solutions might also require additional safety features, like guardrails, safety covers, and emergency stops, depending on the application and its environment.

7. Sanitation

Any conveying solution needs to meet and, ideally, exceed sanitation requirements for your products in its designated zone. That includes any modifications to the conveyor or customizations to integrate it with other process equipment.

Be sure to select only professional sanitary conveyor equipment from a reputable supplier that is designed for use with your food product and be sure any additional integration equipment, including custom hoppers or extenders, does not introduce potential sanitary hazards.

8. Controls and Automation

Finally, think about how your conveyor equipment not only integrates with controls for the equipment it is directly attached to but with systems automating the operation of other equipment and the line itself. 

For example, being able to slow down some types of food processing conveyors, can help prevent bottlenecks further down the line. Also, consider whether you need to add any automated monitoring or performance-tracking equipment. 


To deliver effective conveyor integration for your operation, be it a single-point retrofit of OEM equipment on an existing line or a conveying “backbone” for your entire operation, you will need to find the right partner.

While cheaper, off-the-shelf conveyors may appear to check many of your boxes, choosing purpose-built equipment from a specialist sanitary conveyor equipment maker will save you money over the long run by ensuring:

  • You receive conveyor equipment designed for your specific application
  • Your equipment meets or exceeds regulatory and industry health standards
  • Your conveying systems are fully integrated with your process equipment

Integration is Partnership

That said, sourcing, installing, and integrating sanitary conveyor equipment can be a time-consuming process. The following steps will help you work with an equipment supplier to ensure on-time delivery and rapid integration of your new conveying systems.

  1. Preparedness: Approaching an equipment company with a clear idea of your needs will save time. The above checklist is a start, but for large or plant-wide integrations, allowing your supplier access to your full project plan is ideal. 
  2. Project management: Accurate information will avoid confusion and make it easier to develop a project quote. Double-check your proposed line layout and plant dimensions or allow the manufacturer on-site to do their own measurements. 
  3. Open Communication: Complex integration challenges require close partnership. Your project engineers need to work as one team with conveyor equipment specialists to see to it that you get a long-term solution that meets your needs and budget.
  4. Get Help: Consider handing off your integration challenges to engineers at a leading equipment supplier like PFI. You’ll benefit from our years of specialized experience while taking pressure off your already busy in-house engineering team. 

Projects Scale, Time Doesn’t 

While these tips will help speed along any conveyor integration project, they’re especially critical for plant-wide or new-build installations. 

Here, equipment lead times, installation, and commissioning need to be carefully coordinated with your project deadlines. By working together, we can make sure the product, brand, and bottom line all get the maximum benefit of an efficient, fully integrated conveying system. 

No matter the size of your project, rapid, seamless integration of your conveyor equipment comes with clear short- and long-term benefits, including:

  • Faster commissioning and capacity ramp-up
  • More predictable project costs
  • Faster returns on equipment capital investment
