Efficient reduction with cryogenic screw heat exchanger

Preparation for cryogenic grinding

Van Beek has developed the cryogenic screw to prepare bulk goods for grinding in a process. On leaving the screw the bulk goods are ready for grinding for example in a pin mill. This screw heat exchanger is also suitable for processes where it is important that the products must cool in a short time (quickly), for example in the food industry or in chemical processes to give certain product properties.

Perfect mixing of nitrogen by nozzles and paddles
Due to the extremely low temperature tough products or products that are sensitive to heat input can be reduced more effectively and efficiently. The cryogenic screw freezes the product in a short time by using several nozzles that add liquid nitrogen to the product. The screw heat exchanger is fitted with paddles that ensure good mixing of the product and the nitrogen.

Easy to clean
The conveyor has a twin-walled casing and there is a vacuum for insulation. The screw is easy to remove from the body using a demountable flange on the outlet side. This makes the screw quick and easy to clean.
