Belt type lattice flow rice husking machine and rice husking method

Abstract

The invention provides a belt type lattice flow rice husking machine and a rice husking method. The traditional whitening manner has the main problems of large energy consumption and much broken rice. The reason is that for the traditional technology, coarse rice rotates along with a husking roller in a spiral way in the process of husking and peeling, a gap is formed between a rice blade of the rice husking machine and the husking roller, the rice can penetrate through the gap, the structure causes the relative friction function required by the husking and the peeling to be greatly reduced, and a lot of power can be consumed without any reasons. The rice husking machine comprises a feeding device (1), a whitening chamber (2), a discharging device (3), a transmission device (4) and a machine frame (5), wherein the whitening chamber comprises two groups (rows) of rice husking rooms (9) which are arranged oppositely and are defined by milling belts (6), flow separation bodies (7) and rice sieves (8), and the milling belts wind around rollers (10) at both ends of the machine frame to form annular belts; the distance between the flow separation bodies and the milling belts is below 2mm; the rice sieves are mounted on the outer sides of the flow separation bodies, a negative pressure space (12) is formed between the outer sides of the rice sieves and a casing (11), and the negative pressure space is connected with an air suction fan. The rice husking machine is used for husking the rice.

Description

Technical field: [0001] The invention relates to a paddy processing equipment-rice milling machine. The function of the rice mill is to peel off the surface cortex of brown rice formed after paddy husking to become edible white rice. Background technique: [0002] The rice milling machine has been used in the world for more than 100 years. Its core component, the whitening room, has not had a major technical breakthrough in structure. It is still composed of three parts: rollers, rice sieves, and rice knives. The roller plays the role of grinding the brown rice skin, and the rice knife is used to increase the pressure in the whitening chamber to increase the whitening effect. The main problems of the traditional whitening method are high energy consumption and more broken rice. The reason is that the brown rice in the traditional process rotates spirally with the roller during the milling process, and there is a gap of 10-8mm between the rice knife and the roller of the r...

AI Technical Summary

Problems solved by technology

The main problems of the traditional whitening method are high energy consumption and more broken rice. The reason is that the brown rice in the traditional process rotates spirally with the roller during the milling process, and there is a gap of 10-8mm between the rice knife and the roller of the rice mill. , rice grains can pass through this gap, and the rice milling room is connected as a whole. This structure greatly weakens the relative friction required for milling, and also consumes a lot of power for no reason. The power consumption per ton of rice is generally above 20kw.

At the same time, due to the long distance traveled by the rice grains, the pressure in the whitening room is high, and a considerable part of the energy used for cutting and peeling brown rice during the whitening process is converted into heat, which causes a large temperature rise of the rice grains, consumes energy and brings adverse consequences.
