Abstract: A pelletizer for making pellets from a liquid or semi-liquid food product has two molding rolls between which the food product is formed into pellets. The rolls have teeth of complementary shape, and the teeth of at least one roll have axially spaced apart recesses. The rolls are cooled with a refrigerant during the molding operation. By the means of the pelletizer, frozen pellets are made from a liquid or semi-liquid food product which, prior to molding, is refrigerated into moldable consistency before being supplied to the nip between the two cooperating molding rolls which are cooled during the molding operation so as to form surface-frozen pellets which are thereafter subjected to final freezing.
