A pelletiser (12) for making pellets from a liquid or semiliquid food product has two moulding rolls (28, 29) between which the food product is formed into pellets. The rolls (28, 29) have teeth of complementary shape, and the teeth of at least one roll have axially spaced-apart recesses (34). The rolls are cooled with a refrigerant during the moulding operation. By means of the pelletiser, frozen pellets are made from a liquid or semiliquid food product which, prior to moulding, is refrigerated into mouldable consistency before being supplied to the nip between the two cooperating moulding rolls which are cooled during the moulding operation so as to form surface-frozen pellets which are thereafter subjected to final freezing. |
