Roller conveyors have been a common staple in most packaging environments for quite some time, so it might come as a surprise that it is possible to improve their design, but we have improved the standard of roller conveyors to meet industry needs.
The average gravity roller conveyor is composed of a frame that holds a line of tube rollers that allow products to move across them smoothly without requiring power input from a motor.
Slight inclines cause the product to coast over the rollers.
They are often seen in shipping centers, but they are used in many other environments, including the food industry.
The strict cleaning protocols in food-related plants means that the equipment should be washdown-ready.
Our easy-to-clean roller conveyors have several unique features that qualify them for this specific task.
The first feature, which is common in most of our conveyors, is the stainless steel angle iron construction for the conveyor’s frame.
Most other conveyor frames out there use things like square tube to form the body. We avoid this because square tube is difficult to clean on the inside and it has more surface area to allow for microbial buildup.
The second feature that makes our roller conveyors so easy to clean is the fact that we seal each roller.
Commonly, rollers are made out of open-ended, hollow tubing. This hollow tubing allows a lot of internal surface area for bacteria to latch onto, and it also makes them difficult to clean, as it does with a square-tubing frame.
We solved this particular problem by capping the ends of our rollers with covers that house tight-fitting bearings.
These bearings allow the rollers to spin freely while keeping contaminants from being trapped inside the tubes.
This is just an example of how we take common industry staples and reshape them into something that solves a specific need.

Reduce Cleaning Times With Easy-To-Clean™ Conveyor Systems
Easy-to-clean™ Conveyor Systems give your food processing operations the cleanliness you need to maintain sanitary conditions, prevent contamination and illnesses.
Engineered for clean-in-place applications, our Easy-to-clean™ Conveyors are built out of stainless steel and have an open channel design to help prevent water or moisture from accumulating.
The open design of the side rails of our conveyors allows for very accessible cleaning of the inside of our food grade conveyors. We also employ the use of our specially engineered belt lifters that enable conveyor belts to be opens and cleaned while the conveyor is running.
The ability to clean the conveyors while running allows less time to do the same job. Your conveyor belt doesn’t need to be broken down for a thorough cleaning. Now, take a wrench to the belt lifters, and with a simple quarter turn, the conveyor is open and available for high pressure washdown.
Another sanitary feature our conveyors possess is the fashion in which we build them. Our Easy-To-Clean™ conveyors are manufactured in a way that virtually eliminates standing water as they are at angles in which gravity will allow water to run off and not pool.
To meet cleaning standards, many plants are forced to remove the belting from their conveyors just to have cleaning access to all of the necessary components. Not only is this inefficient, it can also cause you a lot of headaches when everything is put back together.
One particular problem that can occur is incorrect alignment between sprockets on the drive and the conveyor’s belting.
When cleaning is done and the belting is placed back on the conveyor, the belting needs to be aligned so that the sprocket contacts it the right way. If the conveyor is run while the two are misaligned, it can cause a failure or breakage in these components.
Not only is this problem a waste of time, it is also a waste of money because you have to spend a lot for the replacement parts and labor.
Our solution to this problem is to have a system that allows you to clean without removing the belt at all.
Easy-To-Clean™ conveyors are packed with cleaning-oriented features. Optional lift-up ends and belt lifters allow you to raise the belting via a crank to access the important components inside the conveyor without entirely removing the belt.
The side channels of the conveyor have large openings that provide even more washing access without compromising the stainless steel integrity.
On top of that all of the structural pieces are bent to be slightly unleveled, which prevents any flat, level surfaces where water or contaminants could pool up.
Spacers are used at all joints to make sure there aren’t any tight gaps where microbial contaminants can gather.
If you need even more cleaning capability, spray bars can be installed near key cleaning points. They allow you to automatically rinse a specific area that may be difficult to get at with an external sprayer.
If you have troubles with broken belts or sprockets after cleaning, it is definitely worth your time to look into an Easy-To-Clean™ system.
It will last longer and minimize cleaning costs all at once!
There are a number of different types of conveyors on the market today that all accomplish the task of moving an item from one point to another. Aren’t all conveyors alike?
No, I am afraid that there are a lot of conveyors that are in plants today that are being used for the wrong application so let’s look at some of them.
Gravity roller conveyors are pretty much just what the name implies; they use gravity to move an object over a series of rollers to another point. What you have to watch out for here is that the size of the item you are moving fits the size of the rollers.
Boxes, cases and large objects run smoothly on any sized roller. If you have a small item, be aware that you need to have a smaller roller for this application.
Powered roller conveyors are pretty much the same as above with each roller being driven by a rubber belt connected to the next one.
The size of item being moved needs to determine the size of the rollers.
Belt conveyors are just what the name implies, it conveys an item via a belt. There are stainless steel frames, mild steel frames and now the industry is looking at aluminum framing in a lot of applications.
The type of belt being used here is where a good supplier can be a big help. There are friction top belts, directional belts, flat top belts and the list goes on.
The advice we would like to offer here is to sit down and discuss what your needs are with a supplier that has the above options available.
There is danger in just pricing and buying a conveyor. You want the best price on the conveyor that meets and exceeds your needs and will be of good service for years to come!
A conveyor is a type of material handling equipment that helps in moving products, packages, foods or equipment from one area of the plant to another. Conveyors are used to improve plant efficiency.
Because conveyors move such a broad range of items, different conveyor configurations are available to meet the material handling needs of the manufacturer and there many different industries.
Belt conveyors are the most common, followed by, roller conveyors, spiral conveyors, chain conveyors, overhead conveyors, vertical conveyors and conveyor systems, which may use combinations of many different conveyor types.
Conveyors can be made for wet and dry, hot and cold production facilities.
Where unpackaged food comes in direct contact on a conveyor that conveyor needs to meet sanitary requirements.
For example, a conveyor in a meat plant needs to be built usually out of 304 stainless steel and depending on the application 12 gauge strength, and manufactured in such a way to keep areas free from bacteria.
No crevices or jagged edges where bacteria can hide.
The conveyor legs should be built using stainless steel angle to prevent raw product from being trapped inside a hollow leg during clean up.
The conveyor must be built strong enough to with stand high pressure water; it must also stand up to temperature extremes, including caustic chemicals that are part of standard harsh washdown regiments necessary in the meat industry.
A washdown conveyor is just one example, there are many such examples of conveyors that are built to meet the different industry demands.
