Interroll’s asynchronous drum motor (models 113i, 138i, 165i and 217i) has gained approval from the U.S. Department of Agriculture (USDA) for compliance with the guidelines for sanitary design and fabrication of dairy processing equipment. The adoption of certain hygienic standards at dairy plants helps the operators to manufacture safer products. Only dairy products manufactured, processed and packaged in a USDA approved plant may be graded or inspected and identified with official USDA identification. The motor is compact, easy to install and can be cleaned and disinfected regularly using high-pressure water, steam and chemicals. This helps food manufacturers achieve the lowest possible levels of Salmonella, Listeria, E. coli and other harmful microorganisms in the production environment.
