An apparatus for freezing boiled rice has an internally bladed drum rotated at low speed and housing a bladed shaft rotated at a higher speed, the drum having covers at its inlet and outlet ends. A hopper feeds boiled rice in through the inlet cover to an inner bottom face of the drum. Pipe means feed refrigerant into the same zone of the drum. A discharge port in the outlet cover discharges frozen boiled rice and used refrigerant to the exterior.
