Rice polishing machine

Abstract

The invention provides a rice polishing machine which comprises a fan (8); a backing strip (15) is fixedly arranged on a crossbeam (14); a feed opening (1) is fed into a first end above a thruster (10); a discharge port (6) is positioned on the tail end below a polishing chamber (21); spray nozzles (18) are connected onto the ends of a pressure air pipe (3) and a water injection pipe (26); the spray nozzles (18) penetrate through an upper crossbeam (14) and the backing strip (15) and are fed into the polishing chamber (21); and the length of a polishing roll (11) is 1000mm to 2000mm, and the outer diameter of the polishing roll (11) is 150mm to 190mm. The rice polishing machine overcomes the defects that an existing rice polishing machine has a non-uniform dampening method and small output and the rice is easily crushed, and has the advantages of uniform dampening method, low rice crushing rate and large output.

Description

technical field [0001] The present invention relates to a kind of grain machine, more specifically it is a kind of rice polisher for rice processing. Background technique [0002] The rice polishing machine for grinding and polishing the surface of rice grains is widely used in the grain machine industry and has a large market demand. It is supported by a frame, a main shaft crosses the frame, a propeller and a polishing roller are installed on the main shaft, which constitutes the rotating part of the machine, and a sieve plate and a sieve frame are installed outside the polishing roller, and the center of the sieve frame and The center of the main shaft is concentric, and the space between the polishing roller and the sieve plate forms a polishing chamber. The rice to be polished enters the polishing chamber from the feed port, and the rice rolls and squeezes in the polishing chamber. Between the sieve plate and the rice, the rice Under the interaction between the rice an...

AI Technical Summary

Problems solved by technology

The existing polishing machine has the following problems in use: ①. The water injection device is installed in the main shaft, the main water injection pipe is installed in the feeding end of the main shaft, and the auxiliary water injection pipe is installed in the discharge chamber. The main water injection pipe is composed of a pressure air pipe and a water injection pipe. After mixing, it is sprayed out from the nozzle, and only one nozzle of the main water injection pipe and one nozzle of the auxiliary water injection pipe are used for watering. In this way of watering, the middle part of the main shaft has a large amount of water, so that the rice bran in the middle part of the main shaft is relatively wet and easy to block. The holes on the sieve plate; the amount of water at both ends is small, and the ends are relatively dry. Although it is easy to remove bran at both ends, the polishing effect of rice is not good.

Water is applied to the rice in the polishing chamber through the ventilation holes on the main shaft and the ventilation grooves on the polishing roller. The force of the water application device to the polishing chamber is the outward suction of the fan. Practice has proved that this method of water application will cause water splashing. Unevenness, uneven watering will cause partial bran discharge and easy to produce broken rice

②. The output is small, which cannot meet the production needs of rice processing plants. The length of the existing rice polishing machine is relatively short. The movement stroke in the polishing roller will increase, which will easily produce broken rice, and the price of broken rice is only half of the price of rice, so it will seriously affect the quality of rice

There are countersunk holes on the pads, causing unevenness on the pads, and it is easy to produce broken rice
