How a knife-cleaning station with an ultrasonic tank fits the shift, the temperatures that keep protein from baking on, and the steps before disinfection.

Parts and contaminants · 4 min readUltrasonic cleaning of industrial filters for reuseStainless mesh, sintered metal and wire-wound filters can be cleaned and reused many times; paper and felt cannot. Which filters are worth cleaning, how to get the dirt out of the depth of the medium rather than just its surface, and how to prove a cleaned filter is fit to go back into service.
