Problems solved by technology

[0002] After brown rice is processed into germ rice by grinding roller and arc-shaped grinding blade group or grinding belt and flat grinding blade group, although the germ retention rate and germ retention degree of the product are already relatively high, but the distance is higher There is still a lot of room for the rate and degree of germ retention and further reduction of grain loss

Embodiment approach 1

[0019] like figure 1 , This embodiment includes a grinding roller 1 , a grinding plate support seat 2 , an arc-shaped grinding plate 3 , and a grinding chamber 4 . The inner surface of the arc-shaped grinding plate 3 is an arc-shaped cylindrical surface, and its axis coincides with the axis of the grinding roller 1, and the outer surface of the arc-shaped grinding plate 3 is fixed with the grinding plate support seat 2. The gap between the inner surface of the arc-shaped grinding plate 3 and the grinding roller 1 forms a grinding cavity 4 .

[0020] like figure 1 , the grinding roller 1 rotates around the direction of the arrow, and at the same time, the arc-shaped grinding plate 3 reciprocates along the axis of the grinding roller 1 together with the grinding plate support seat 2 . The brown rice enters the milling chamber 4 from one end of the milling chamber 4, and in the milling chamber 4, the rotation of the milling roller 1 makes the brown rice move toward the other en...

Embodiment approach 2

[0023] The arc-shaped grinding plate 3 in Embodiment 1 is made of rubber, which is elastic and has the same properties on the arc-shaped cylindrical surface, which can ensure that each grain of brown rice can be subjected to sufficient grinding pressure. The hardness of the rubber is smaller than that of the brown rice. When the brown rice moves in the grinding chamber 4, it will not be subjected to rigid force and impact, the broken rice rate of the product is significantly reduced, and the germ retention rate and germ retention degree are significantly improved.

Abstract

The invention discloses a milling device, and relates to rice processing, in particular to moderate processing of rice, and solves the technical problems of how to reduce the broken rice rate of germ-remaining rice and improve the germ-remaining rate and germ-remaining degree of the germ-remaining rice. The milling device comprises a milling roller, a milling plate supporting seat, an arc-shaped milling plate and a milling cavity; the inner side surface of the circular-arc-shaped milling plate is a circular-arc-shaped cylindrical surface, the axis of the circular-arc-shaped milling plate coincides with the axis of the milling roller, and the outer side surface of the circular-arc-shaped milling plate is fixed with the milling plate supporting seat; and a gap between the inner side face of the arc-shaped milling plate and the milling roller forms the milling cavity. The milling roller rotates around the axis of the milling roller, and meanwhile, the arc-shaped milling plate and the milling plate supporting seat reciprocate along the axis of the milling roller, so that the broken rice rate of a product is obviously reduced, and the germ-remaining rate and the germ-remaining degree are obviously improved. The milling device is mainly used for moderate processing of rice.

Description

technical field [0001] The present invention relates to rice processing, in particular to the moderate processing of rice. Background technique [0002] After brown rice is processed into germ rice by grinding roller and arc-shaped grinding blade group or grinding belt and flat grinding blade group, although the germ retention rate and germ retention degree of the product are already relatively high, but the distance is higher There is still a lot of room for the rate and degree of germ retention and further reduction of grain loss. Contents of the invention [0003] Technical problem to be solved: [0004] Reduce the broken rice rate of rice with germ, and increase the germ retention rate and germ retention degree of rice with germ retention. [0005] Technical solutions: [0006] The invention comprises a grinding roller, a grinding plate support seat, an arc-shaped grinding plate and a grinding cavity. The inner surface of the arc-shaped grinding plate is an arc-sha...
