Consistent quality cleaning within a tight time frame is a concern of all food processors. Given the size of tunnel and spiral freezers, manual cleaning is time consuming and produces inconsistent results. The FPS slim profile CIP system can be retrofitted into existing tunnels, low tension spirals and self-stacking spirals to address all sanitary concerns. With efficient performance and recirculating cleaning cycles, freezers are effectively cleaned after every shutdown and ready to operate after the CIP cycle.
