Problems solved by technology

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

Embodiment approach 1

[0020] Such as figure 1 , This embodiment includes a roller 1, a grinding belt 2, a grinding plate support seat 3, an arc-shaped grinding plate 4, and a grinding chamber 5. Such as figure 2 , Both ends of the roller 1 are provided with ribs 1-1, the grinding belt 2 is set on the roller 1, and the ribs 1-1 limit the movement of the grinding belt 2 along the axis of the roller 1. The inner surface of the arc-shaped grinding plate 4 is an arc-shaped cylindrical surface, and its axis coincides with the axis of the roller 1, and the outer surface of the arc-shaped grinding plate 4 is fixed with the grinding plate support seat 3. The gap between the inner surface of the arc-shaped grinding plate 4 and the grinding belt 2 forms a grinding chamber 5 .

[0021] Such as figure 1 , the roller 1 rotates around the direction of the arrow, the part of the grinding belt 2 in contact with the roller makes a circular motion, and at the same time, the arc-shaped grinding plate 4 moves back ...

Embodiment approach 2

[0024] The arc-shaped grinding plate 4 in Embodiment 1 is set as 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 5, 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 grinding device, which relates to rice processing, and in particular to moderate processing of rice. The technical problems of reducing the broken rice rate of the germ-remaining rice and improving the germ-remaining rate and germ-remaining degree of the germ-remaining rice are solved. The grinding device comprises a roller, a grinding belt, a grinding plate supporting seat, an arc-shaped grinding plate and a grinding cavity; the grinding belt is sleeved on the roller, and the flanges at the two ends of the roller limit the grinding belt to move along the axis direction of the roller; the inner side surface of the arc-shaped grinding plate is an arc-shaped cylindrical surface, the axis of the arc-shaped grinding plate coincides with the axis of the roller, and the outer side face of the arc-shaped grinding plate is fixed with the grinding plate supporting seat; and a gap between the inner side face of the arc-shaped grinding plate and the grinding belt forms the grinding cavity. The roller rotates around the axis of the roller, the part of the grinding belt making contact with the roller does circular motion, and meanwhile, the arc-shaped grinding plate and the grinding plate supporting seat do reciprocating motion along the axis of the roller together, and in this way, the broken rice rate of the product is obviously reduced, and the germ-remaining rate and germ-remaining degree are obviously improved. The invention 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 rice with retained germ by rollers and arc-shaped grinding blades or grinding belt and flat grinding blades, although the germ retention rate and degree of germ retention of the product are already relatively high, but the germ retention rate of the product is higher. There is still a lot of room to further reduce 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 includes a roller, a grinding belt, a grinding plate support seat, an arc-shaped grinding plate and a grinding chamber. Ribs are arranged at both ends of the roller, the grinding belt is sheathed on ...
