Interroll Asynchronous Drum Motor USDA certified

The certification is based on equipment review and an examination of engineering drawings, with the participation of design engineers. The adoption of certain hygienic standards at dairy plants helps the operators to manufacture safer dairy products. Only dairy products manufactured, processed and packaged in a USDA approved plant may be graded or inspected and identified with official USDA identification. Interroll has created the most hygienic conveyor drive available on the market to ensure that food manufacturers are in compliance with strict food safety and material handling regulations.

Typically, conventional gear motors are bulky, difficult to install and most importantly, non-hygienic and virtually impossible to be spotlessly cleaned. In contrast, the Interroll Drum Motor is compact, easy to install and can be cleaned and disinfected regularly using high pressure water, steam and chemicals. This helps dairy and food product manufacturers achieve the highest possible hygiene standards and provides for the lowest possible levels of Salmonella, Listeria, E. coli and other harmful microorganisms in the production environment.

"Hygiene is extremely important to us and that’s why we rely on the Interroll drum motor,” said Jeff Evers of Butterball LLC.

Butterball uses Interroll drum motors in food production and is one of the largest global turkey providers in the world, exporting over 100 million pounds of products annually to more than 50 countries.

"We understand how critical food safety is in processing environments,” said Tim McGill, President of Interroll North and South America. "For this reason, we continue to evolve our products to be the best on the market so that our customers can focus on their business without worrying about the dangers of operating in a potentially unclean environment. Extensive research and development have been put into the Interroll Drum Motor and our participation in the voluntary certification process speaks to the confidence we have in it.”

Interroll introduces new Multiprofile for driving various conveyor belt types

Interroll has developed Multiprofile - a new profile for its asynchronous drum motors and synchronous drum motors, which can be used to drive various conveyor belts from different manufacturers using only one Interroll Premium Hygienic PU Profile. Incorporating frequency converters, these drums and Multiprofile provide positive and controlled drive of various belt types.

This translates into higher flexibility and increased efficiencies as customers can replace belts without having to replace the drum motor. It can reduce the time needed to retrofit and perform maintenance work on the conveyors quite significantly, whilst also contributing to lower storage costs.


The Interroll Multiprofile is manufactured using the "Interroll Premium Hygienic PU”, which is also a new development. This extremely hygiene friendly material complements the Interroll product line that meets EHEDG guidelines. This new material for rubber coating drum motors is particularly well suited for positively driven belts and is known for its extremely smooth surface that prevents bacteria from forming on the material.

Besides the low operational noise level and its high resistance to oil, grease and chemicals, the Interroll Premium Hygienic PU also stands out due to its much lower friction.
