For cooling, water or glycol is circulated through the unit’s heat exchanger plates. For heating, steam commonly is used, but hot water or thermal oil can be employed. The heat transfer fluid flows counter-current to the product flow, and a vertical configuration of heat exchanger plates provides a large heat-transfer surface area in a compact unit. Unlike rotary drum or fluid-bed processors where air is in contact with the product, this indirect method of heat transfer maintains product quality while eliminating the need for air-handling equipment. Multiple plate 0062anks can be mounted in a single piece of equipment.
