Key Technology introduced a rotary polish as the new standard finish on its vibratory and horizontal motion conveyor beds. Replacing the 2B mill finish on Iso-Flo, Impulse and Horizon conveyors and processing systems, Key’s rotary finish provides a smoother stainless-steel surface that resists bacterial attachment and biofilm formation. Additionally, it provides a more constant Ra value of less than 10 µin, which better resists the attachment and accumulation of bacterial cells in fruits, vegetables, potato products, meat and dairy.
