Chain type grinding plate structure applied to rice husking process

Abstract

The invention provides a chain type grinding plate structure applied to a rice husking process, comprising a floor mounting rack (110); a rectangular horizontal plate (111) is fixedly arranged on thetop of the mounting rack (110); two vertical plates (112) are fixedly arranged on the upper end face of the horizontal plate (111), and disposed at an interval; two chain plate mechanisms (120) arranged in parallel are disposed between the two vertical plates (112), and the distance between the two chain plate mechanisms (120) is adjustable; two connecting mechanisms (130) are fixedly arranged onthe sides, close to each other, of the two chain plate structures (120); the two connecting mechanisms (130) and the two chain plate mechanisms (120) surround to form a whitening chamber (133) which is narrow and long and has an upper opening and a lower opening; a grinding plate (128) runs reversely to squeeze to husk brown rice in the whitening chamber (133), the brown rice is filled from the upper opening of the whitening chamber (133), and a mixture of white rice and bran is discharged from the lower opening.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a chain grinding plate structure applied to rice peeling processing. Background technique [0002] The rice processing process in a rice factory generally goes through five sections: cleaning section, huller and paddy separation section, rice milling section, finishing section and by-product sorting. The rice milling section is one of the most important sections of rice processing. The equipment is a rice mill. The rice mill is composed of a frame, emery rollers, rice knives, rice sieves, feed hoppers, discharge nozzles, motors, etc. When working, the clean brown rice processed by the previous section is processed from the feed The hopper enters the whitening chamber of the rice machine, and as the emery roller rotates, the brown rice spirals forward along the surface of the emery roller, and is subjected to great extrusion force and friction force, and the surface of the...

[0002] The rice processing process in a rice factory generally goes through five sections: cleaning section, huller and paddy separation section, rice milling section, finishing section and by-product sorting. The rice milling section is one of the most important sections of rice processing. The equipment is a rice mill. The rice mill is composed of a frame, emery rollers, rice knives, rice sieves, feed hoppers, discharge nozzles, motors, etc. When working, the clean brown rice processed by the previous section is processed from the feed The hopper enters the whitening chamber of the rice machine, and as the emery roller rotates, the brown rice spirals forward along the surface of the emery roller, and is subjected to great extrusion force and friction force, and the surface of the emery roller rotating at a certain linear speed is constantly rubbed away from the surface of the brown rice. The cortex finally passes through the spiral groove on the emery roller, and the mixture of white rice and rice bran is pushed to the outlet and flows out from the discharge nozzle. At the same time, under the action of strong suction, the white rice and rice bran are forced to be separated and discharged. The disadvantage is that the sand The contact area between the rod and the brown rice is limited, resulting in low peeling efficiency. Moreover, the adjustment of the pressure between the iron rod or the sand rod and the brown rice is inconvenient, and the fineness of the white rice cannot be controlled. In order to overcome the above-mentioned disadvantages, it is necessary for the present invention to provide a The structure is ingenious, the principle is simple, the operation is convenient, the efficiency of rolling and peeling is high, and the friction pressure on brown rice can be quickly adjusted.
