AIR TREATMENT PLANT FOR FOODSTUFF WITH CONVEYOR BELT PERIODICALLY DRIVEN IN OPPOSITE DIRECTION TO THE TROUGHFEED DIRECTION

摘要

An air treatment plant, e.g. a freezing plant for foodstuffs, comprises ahousing (1), an elongate trough (12) provided there-in for receiving the foodstuff to be treated, a heat exchanger (13), and a fanassembly (14) for producing an air flow circulatingthrough the heat exchanger, up through the trough and back to the heatexchanger. The bottom of the trough comprises a forami-nated conveyor belt (16). The conveyor belt (16) is driven by an electricmotor having a control unit for at least periodically driv-ing the conveyor belt in a direction opposite to the throughfeed direction ofthe foodstuff in the trough (12).
