How many different whitening methods do rice mills have?
- Sep 29, 2018 -

According to the nature of its action, the rice milling machine is mainly divided into two types: rubbing and whitening and milling and whitening; the principle of rubbing off the whitening: the rice grains are in the whitening chamber of the rice milling machine, colliding under a certain pressure, the rice grains and the roller Contact, the speed of collision is obtained. The rice and rice with a certain speed collide with each other to produce relative motion. The rice with lower speed collides with the inner wall of the milled rice sieve and other components, and also has relative motion. The friction in three kinds of collision movements The force causes the rice grain layer to slide relative to the surface of the endosperm, and the skin layer is broken and peeled off.

The principle of milling and whitening: brown rice is milled in the white rice machine. Under the pressure, the sharp edges of the high-speed moving diamond grains collide with each other to produce relative motion. The lower speed rice collides with the inner wall of the rice sieve to produce relative motion. .

The peripheral speed of the rubbing away from the whitening is the speed at which the rice grains are in contact with the roller and the collision is obtained, and the milling and whitening is obtained by colliding the rice grains with the sharp edges of the high-speed moving diamond gravel. The pressure characteristics of the two whitening whitening chambers are different. The two kinds of whitening are the collision of the rice grains with the roller, the collision between the blurs, the three kinds of friction between the rice grains and the white inner wall and other members.
