Description

  The present invention has a function of storing brown rice at a low temperature and a function of taking out a certain amount of brown rice and polishing the rice to a predetermined degree of milling, and a rice polishing function of taking out only the portion to eat brown rice which has been stored at low temperature just before cooking. It relates to cold-insulated rice straw and is intended to prevent brown rice from being affected by the temperature rise due to milling.

  Patent Document 1 is known as a cold-preserved rice with a function of milling rice. In the rice bowl of Patent Document 1, a storage section for storing brown rice, a weighing section for discharging a desired amount of brown rice from the storage section, and a weighing section discharged from the weighing section are housed inside a longitudinally elongated rectangular parallelepiped housing. The milled rice parts that receive brown rice are arranged in order from the top. The storage section is provided with a heat insulating material with a certain gap around the periphery, and indirectly cools the stored brown rice by circulating air cooled by the cooling device in the gap. The measuring unit is equipped with a measuring container capable of measuring a predetermined amount, and pays out a proper amount of brown rice necessary for one cooking to the rice milling section. The milled rice part rotates the milled rice blade inside the rice milling container, stirs the brown rice put in the rice milling container, and separates it into rice bran and white rice.

  Since the cool air by the cooling device is not circulated in the milled rice part in this rice bran, a temperature difference with the storage part occurs and dew condensation tends to occur in the brown rice. In addition, since the rice milling section is structured to accommodate the rice milling container and the driving mechanism (motor, pulley, belt) of the rice milling blades in a box-shaped case, the inside of the rice milling section is exhausted by the exhaust heat from the motor generated by stirring. It becomes a condition where it is heated and dew condensation is more likely to occur.
