Grinding vertical-type grain polisher

Abstract

Provided is a grinding vertical-type grain polisher provided with a resistance body adjustment device such that the projection amount of resistance bodies used for adjusting the degree of grinding does not need to be manually adjusted by an operator. A rice bran removing metal net cylinder comprises, in plan view, rice bran removing metal net cylinder parts (28) divided into a plurality of parts in the circumferential direction, and a plurality of support columns (33) which are arranged with spaces therebetween in the circumferential direction in order to secure both ends of the rice bran removing metal net cylinder parts (28) that are divided into a plurality of parts. Each support column (33) is provided with a long resistance body (34) that suppresses circumferential direction rice grain movement resulting from the rotation of a grinding-type polishing roller (26). The resistance body (34) is impelled by an elastic member (37) towards a position that protrudes into a polishing chamber (30), and is provided so as to be freely movable in the radial direction, due to the resistance (pressure force) from the rice grain, to a position that is away from the polishing chamber (30).

Description

technical field [0001] The present invention relates to a grinding type vertical milling machine provided with a resistance body device for regulating the movement of grains and adjusting the degree of grinding of grains when milling grains in a grinding manner. Background technique [0002] As a conventional rice mill, the rice mill described in patent document 1 exists. The rice milling machine will be described with reference to the drawings. Figure 15 It is a cross-sectional view of the milling part of an existing milling machine, and a plurality of grinding rollers 102 and a plurality of spacers 103 are formed on the grinding roller body alternately overlapping along the longitudinal direction, and it is shown that it is fitted and installed on the main shaft 101. part of the state. In this figure, on the outside in the radial direction of the grinding roll 102, a porous cylindrical body 105 is provided to surround the grinding roll 102 at intervals from the outer per...

AI Technical Summary

Problems solved by technology

[0006] However, in the above-mentioned rice milling machine, there are a plurality of protrusion adjustment mechanisms 108 provided on each support 106 (in Figure 15 In the figure, four places are shown in the circumferential direction, and there are also many places in the direction of the main axis 107), and there is a problem that it takes a long time to adjust

In addition, there is also the situation that the operator is unskilled in adjusting the protrusion amount adjustment mechanism 108, and when the gap between the resistance body 107 and the outer peripheral surface of the grinding roller 102 is set to be extremely narrow, the grain grains will be caught in the gap, Problems such as broken rice when the grains are rice grains
