With the help of our cooling screws, which are equipped with a cooled trough and conveyor screw, the desired temperature can be reached by indirect cooling. The product is conveyed by a spiral screw, which gently transports it from the inlet to the outlet. The surface of the screw conveyor and its trough are cooled by a fluid, usually chilled water. The water circulates in a double jacket welded to the outside of the trough. The design of the cold exchange surface ensures that the desired cooling temperature is achieved.
