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:

 

 

HOW DOES AN INCLINE BELT CONVEYOR WORK?

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.

COMPONENTS OF AN INCLINE BELT CONVEYOR

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.

 

OPERATION STEPS OF AN INCLINE BELT CONVEYOR

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.

BENEFITS OF AN INCLINE BELT CONVEYOR

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

HOW DOES A BUCKET ELEVATOR WORK?

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.

COMPONENTS OF A BUCKET ELEVATOR

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.

OPERATION STEPS OF A BUCKET ELEVATOR

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.

BENEFITS OF A BUCKET ELEVATOR

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

INCLINE BELT CONVEYORS VS. BUCKET ELEVATORS

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.

WHEN TO USE AN INCLINE BELT CONVEYOR

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.

WHEN TO USE A BUCKET ELEVATOR

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.

ADDITIONAL PURCHASE CONSIDERATIONS

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.

JUST THE LIFT YOU NEED: BUCKET ELEVATORS IN FOOD HANDLING 

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. 

A WORKHORSE WITH PEDIGREE

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

RIGHT SIZE, RIGHT PRICE

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.

IS A BUCKET ELEVATOR RIGHT FOR YOU? 

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.
