A cooling die for extruding of high moisture extrudate food products having a cooling die body in which are defined a plurality of extrudate flow channels extending between an inlet end of the cooling die that is attachable to an extruder and an outlet end for delivery of cooled-down extrudate, and coolan t cavities located in heat-exchanging communication with the extrudate flow channels and connectable to a source of coolant, characterised in that the cooling die body consist of a plurality of thick plates having first and second channels extending between and opening at the planar surfaces of the thick plates, and in that the plurality of thick plates are stacked and fastened together such that the openings of the first and second channels of adjoining plates are respectively aligned with one another, whereby the firs t channels form said plurality of extrudate flow channels and the second channels form a plurality of discrete coolant channels extending through the length of the cooling die body. |
