Moving product in the food or medical industry requires a conveyor system to be not only sanitary, but also designed for easy disassembly and daily cleanings. (Steps in the disassembly process are shown in the photos.)
When it comes to durability, start with the conveyor''s frame. Continuous TIG welding 304 SS framing eliminates fasteners in the food zone and provides a more sanitary environment.
As for bearings, 400 SS H1 FDA filled lubricant bearings are among the highest rated, and they are engineered for daily washings. Bearings should be enclosed in cast SS housings for peak performance against corrosion.
Conveyor systems in a sanitary environment need to be washed down on a daily basis. Toolless tip-up pulley and toolless belt lifters allow operators access in seconds to both the underside of the belt and the conveyor''s frame for cleaning. Sanitary conveyors should also have cutouts along the frame for additional access. Beware of conveyors that have flat horizontal frame components as these pose yet another collection point for food scraps to collect. Rather, look for a frame designed with round cross members that eliminate any potential for food scrap collection on horizontal surfaces, and also provides complete drainage.
Ease of Disassembly
When cleaning calls for removal of the belt, it must be done quickly to avoid costly downtime. Plastic chain and urethane belts can be detached in seconds by simply removing one pin -- a great time saver.
Another feature to consider is how fast conveyors can be disassembled. Some conveyors, including the drive components, can be taken apart without tools by just one operator in as little as three minutes.
A good sanitary conveyor should be able to withstand daily high-pressure washdowns from anywhere between 100 and 1,500 psi. Additionally, since soap and water, and foaming chlorinated cleaners are common cleaning solutions used in the food and medical industries, be sure the conveyor system is rated to handle these basic but challenging cleaning agents.
