Novel rice milling chamber

Abstract

The invention discloses a novel rice milling chamber. The novel rice milling chamber comprises a mounting frame assembly connected with a rice milling machine rack; a plurality of hollow cylindrical screen drums and a plurality of annular adjusting rings are arranged on the mounting frame assembly; the multiple screen drums are sequentially arranged at intervals in the rice grain flowing direction; each adjusting ring is arranged between every two adjacent screen drums; inner channels of the screen drums and inner channels of the adjusting rings are connected to form a rice milling channel extending in the rice grain flowing direction; a rice milling main shaft extending in the axial direction of the rice milling channel is arranged in the rice milling channel; the screen drums are used for being matched with the rice milling main shaft to mill rice grains in the rice milling channel; and the adjusting rings are used for being matched with the rice milling main shaft to change the flow area of the rice milling channel, so that rice grain flow flowing through the rice milling channel is disturbed, the rice grains are easier to roll, and the friction and collision borne by the rice grains are more uniform. According to the novel rice milling chamber, the circulation area of the rice milling channel is changed, and then the rice grain flow flowing in the rice milling channel is disturbed, so that the rice grains are rolled and collided more.

Description

technical field [0001] The invention relates to the technical field of rice milling machines, in particular to a novel rice milling chamber. Background technique [0002] The rice milling room is an important part of the rice milling machine. The rice grains roll forward in the rice milling room, rubbing and colliding with the sieve in the rice milling room, breaking and wiping off the cortex on the surface of the brown rice. [0003] The wall of the traditional rice milling chamber is smooth, the friction between the rice grains and the rice milling chamber wall is very small, and the chance of the rice grains rolling over is less; the rice grains close to the rice milling main shaft are more likely to roll over due to the action of the screw propeller and the rice milling roller, resulting in The friction of the rice grains in the flow channel in the chamber is uneven, the rice grains with less friction are not sufficiently milled, and the rice grains with more friction ar...
