  • Patent number: 6120828
    Abstract: To provide an apparatus for producing frozen cooked-rice in an appropriately individuated state without needing complicated and special apparatus constructions, and without breaking down the individual grains of rice, cooked rice is primary-frozen as an entire block by cold air blown from air blast supply devices into the state where the individual grains of rice are not frozen up to their cores. The cooked-rice thus partly primary-frozen is brought by compressed cold air blown by a compressed-cold-air intermittent supply tube and/or by a rotary disjointing device comprising a rotary comb and a stationary comb into the form of appropriate-size blocks or small lumps which are then secondary-frozen by cold air blown from air blast supply devices into a state where the individual grains of rice are frozen completely up to their cores.
