いた。The grinding polishing machine performs polishing by high-speed rotation of the grinding rotor, and its rotation speed has properties suitable for both germ rice and sake-brewing rice. In order to maintain the quality and stabilize the milling load, it is already known that a rice grain cooling device is installed in the front stage of the rice milling equipment. Since high-level milling is performed at a low yield rate of 15% to 30%, the hardness of the rice grain increases and the calorific value increases, and this temperature rise causes the rice bran (starch powder) to
The rice grains are swollen and guided by the trochanter, which obstructs the flow of the rice grains as they revolve in the milling chamber, causing a squeak phenomenon, resulting in overload due to unstable load, resulting in inoperability. This has had disadvantages, such as a rise in grain temperature that reduces the adhesion of the germ and causes it to separate from the rice grain surface, significantly reducing the germ survival rate.

精米装置を開発して提供せんとするものである。In view of the above points, the present invention has been developed by connecting a cold air device consisting of a cooler to a cold air supply path communicating with a milling chamber formed by fitting a milling trochanter into a porous-walled bran removal milling cylinder. A powerful cold air is sent to the milling room of the rice milling equipment to greatly suppress the heat generation of rice grains generated during milling, and the wind force spreads the density of rice grains in the rice milling room to promote bran removal. This completely prevents the squeak phenomenon caused by the peeling of the bran and the detachment of the germ, as described above, and constantly performs a high-efficiency whitening action to produce high-quality germ-free rice, sake-brewed rice, and foreign rice without spots. The aim is to develop and provide a high-performance cooling rice milling device that processes and mass-produces rice, etc.

The cooling rice milling apparatus of the embodiment is generally designated by the reference numeral 1. A porous-walled bran removal and whitening cylinder 3 is installed horizontally inside the machine frame 2, and a grinding and whitening trochanter 5 consisting of a plurality of cylinders is mounted on a whitening trochanter shaft 4 which is mounted inside the whitening cylinder 3. The whitening room 6
A rice bran removal chamber 7 is provided on the outer periphery of the rice bran polishing cylinder 3 and is connected to an exhaust fan 8, and an air supply chamber 9 provided on one side of the rice polishing chamber 6 is connected to a cooling air device 11 consisting of a cooler 1o. Connected to the wind pipe 12,
13 is a heat exchanger for the cooler 10 installed in the wind pipe 12; 14
15 is a cold air supply path for supplying cold air from the cold air device 11 to the milling room 6, and the supply path 15 is connected to the wind pipe 12. It is formed by the ventilation openings provided in the ventilation chamber 9 and the grinding and polishing trochanter 5.

なる。With the above-mentioned configuration, when raw brown rice is supplied to the cooling rice polishing device @1 and the device is started, while the brown rice is milled by the rotation of the grinding and polishing trochanter 5, the cold air generated in the cold air device 11 is removed. Flows out into the milling room 6 via the cold air supply path 15 due to the suction force generated by the rotation of the exhaust fan 8, so the heat generation of the rice grains that occurs during milling is largely suppressed by the cold air, and the density of the rice grains is reduced by the wind force. The rice bran powder on the surface of the rice grains is ejected into the bran removal chamber 7 through the holes in the porous-walled rice bran removal cylinder 3, which prevents the above-mentioned bran peeling due to the rise in grain temperature of milled white rice. The squeak phenomenon and the 1lli theory of germs caused by this process are completely prevented, and the moisture evaporation of the milled white rice is minimal, and the rice is milled to a predetermined level of whiteness by the high-efficiency milling action and then taken out of the machine. become.

しである。Note that the cold air from the cold air device 2 is not a natural cold air from a well or the like, but is a strong cold air whose temperature is controlled by a cooler, which may cause a decrease in germ adhesion due to an increase in grain temperature, and a decrease in the bran of sake-brewed rice. The squeak phenomenon caused by swelling can be completely prevented. In addition, in the cooling rice milling apparatus 1 of the first embodiment, when cold air is supplied by a blower, the temperature of the cold air rises and changes during the blowing stroke, so the suction force of the exhaust J1118, which does not change the temperature, supplies cold air at a predetermined temperature to the milling room. It is designed so that the sugar-containing wind is removed from the machine through the bran removal seedlings.
