Working principle of Anlu Tianlong Machinery Co., Ltd. rice polishing machine

After the brown rice is whitened by the rice machine, the broken rice and bran powder are removed, and a small amount of automatic spray is applied to water to moisten the rice (which reduces the binding force between the endosperm and the rice bran. Due to the small amount of added water, only a thin film is formed on the surface of the rice grain, and the polishing time is not long, which has no effect on the water content of the rice). The brown rice enters the polishing room of the polishing machine. Under certain pressure and temperature, the surface of the rice grain is polished by friction, and a 20-50 micron thick gelatinization layer is formed on the surface of the rice grain, which can not only remove the floating sugar on the surface of the rice grain, but also play a role of pre gelatinization and gelatinization of the starch on the surface of the rice grain. The starch gelatinization makes up the cracks. So as to obtain the appearance quality of crystal clear color and improve the storage performance and commodity value of rice.
