Title: Process for freezing cooked rice

Abstract: A process for freezing cooked rice utilizes a rotary drum, and blade elements rotated within the drum. A mass of cooked rice is fed into the drum, and a liquid refrigerant is jetted into the drum for freezing the rice. The mass of rice must be separated into individual grains. This is achieved by impact of the blades against the mass of rice. The degree of impact must be sufficient to separate the mass into individual grains, but must not be such as to damage the grains. The invention selects a range of speeds of circumferential rotation of the blades which gives separation without damage.
