ABSTRACT:
Cooked rice is continuously fed rice at the entrance (6) of conveyor system (4) where the rice (a) is cooled to a chosen temperature using cool air jets from above and below the conveyor. The cooled rice is then transferred to another mesh conveyor (22) where cold air jets blow sub-freezing air onto the rice surfaces, but not the cores (a'), of the grains of rice are frozen and are covered with ice crystals (b). The surface-frozen rice is then transferred onto a third mesh conveyor (33) where two sets of counter-rotating comb rollers (32) break up the surface-frozen rice grains into separate grains of surface-frozen rice. The separate grains of surface-frozen rice is then transferred to a fourth mesh conveyor (42) where the grains of rice are completely frozen to the core.
