Rotary polish is a new standard finish on vibratory and horizontal motion conveyor beds. Replacing the 2B mill finish on popular Iso-Flo®, Impulse®, and Horizon™ conveyors and processing systems, this rotary finish provides a smoother stainless steel surface that resists bacterial attachment and biofilm formation. Compared to the industry-standard 2B finish, the rotary polish within the product contact zones improves sanitation to maximize food safety. Available immediately on all U.S.-manufactured conveyors and to be introduced on all European-manufactured conveyors, both of which are shipped to customers worldwide, the new rotary finish on the conveyor bed helps food processors improve equipment hygiene. Surface roughness is measured by an Ra value (roughness average) that refers to the peaks and valleys of the metal’s surface in microinches or micrometers. Compared to a 2B finish on stainless steel that often varies from 10 to 40 µin (0.254 to 1.016 µm) Ra, Key’s rotary finish provides a more constant Ra value of less than 10 µin (0.254 µm). Consistently smooth rotary polished surfaces better resist the attachment and accumulation of bacterial cells, which is desirable for all food products including fruits, vegetables, potato products, snacks, and nuts as well as meat and dairy.
