Rice processing equipment

Abstract

The invention relates to rice processing equipment. The rice processing equipment comprises an outer cylinder and an inner cylinder, and an annular cavity is formed between the inner cylinder and theouter cylinder; a transverse filter plate is inserted in the cavity; a first cavity body is formed above the filter plate and internally provided with a first negative pressure fan connected to the outer wall of the inner cylinder, and a bran shell recycling box is arranged on the outer side of the first cavity body; a second cavity body is formed below the filter plate, a discharging opening is formed in the bottom of the second cavity body, and inner polishing pellets and outer polishing pellets are arranged in the second cavity body; a third cavity body is formed in the inner cylinder, anda vertical rod penetrates through the interior of the third cavity body; the bottom end of the vertical rod is connected with a motor, and the top end of the vertical rod is connected with a transverse plate; the vertical rod is connected with a second negative pressure fan; an inner gear ring is arranged between the transverse plate and the outer cylinder, and a vertical rotating shaft is rotatably arranged on the transverse plate; the rotating shaft is connected with a straight gear engaged with the inner gear ring, and the bottom of the rotating shaft is rotatably connected with a transverse shaft; and one end of the transverse shaft is connected with a third negative pressure fan. According to the scheme, both bran shells and broken rice are prevented from entering the bran shell recycling box, and thus the bran shells and the broken rice are separated.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice processing equipment. Background technique [0002] Rice polishing is a very common process in existing grain processing. Rice polishing machines are widely used in grain processing enterprises; existing polishing machines use polishing rollers to polish rice, and when polishing rice There will be a certain rolling force, which is prone to broken rice, and it is easy to cause uneven polishing during polishing. Part of the surface of the rice grain will be over-polished, while part of the surface will not be polished. [0003] In order to solve the above-mentioned technical problems, the invention patent with the Chinese patent application number CN201410517772.2 discloses a polishing shot type rice polishing machine. But, in this polishing shot type rice polishing machine, the screen cloth of upper polishing chamber is positioned at the outside of upper polishing ...

AI Technical Summary

Problems solved by technology

However, as we all know, during the polishing process of rice, due to the high polishing temperature, it is easy to produce broken rice, and because the particles of broken rice are small, it can also enter the chaff powder suction through the screen of the upper polishing chamber and the screen of the lower polishing chamber. box, so that the broken rice is mixed with the bran husks, resulting in waste of broken rice
