A screening and grading equipment for rice processing

Abstract

The invention discloses a screening and grading equipment for rice processing, comprising an air selection box, an air duct is fixed on one side wall of the air selection box, a power shaft is arranged in the air duct, and the power shaft is installed on the air duct. Has fan blades. The present invention only uses one motor as a power source, and can make the whole equipment operate stably, which can reduce energy consumption and cost well, and at the same time, through the cooperation of various mechanisms, the equipment can operate stably, and it is convenient for Overhaul can quickly conduct preliminary screening of rice raw materials, which can effectively improve the quality and efficiency of screening, solve the problem that the accumulation of rice raw materials affects the screening quality, and remove the moth-eaten, hollow and other problems of rice grains through wind selection. , to better grade the rice, further improve the quality of the rice, and can effectively classify and collect the graded rice grains to avoid confusion, and at the same time facilitate the cleaning of the air separator through the door panel.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a screening and grading device for rice processing. Background technique [0002] Rice is one of the traditional staple foods in our country, and it is also the main food of the people in southern my country. Rice is a basic food for supplementing nutrients. In addition to being rich in carbohydrates, it also contains protein, fat, vitamins and 11 kinds of minerals, which can provide comprehensive nutrition for the human body. The carbohydrates in rice are mainly starch, and the protein contained is mainly rice gluten, followed by rice glue and globulin. The biological value of the protein and the composition ratio of amino acids are higher than those of wheat, barley, millet, corn and other cereal crops. High, with a digestibility of 66.8%-83.1%, which is also one of the higher cereal proteins. [0003] In the process of rice processing, due to various reasons, the siz...

AI Technical Summary

Problems solved by technology

[0003] In the process of rice processing, due to various reasons, the size of the processed rice particles is not exactly the same, there will be some larger particles, some smaller particles, and there will be a certain amount of dust, but in the sales process , The price of rice with large grains and rice with small grains is completely different, and if the grains of rice sold are uneven in size, or even mixed with dust, the quality and sales price of rice will be seriously reduced. Therefore, in order to improve the commercial value of the product, To get better quality rice, it is necessary to screen large grain rice and small grain rice at the end of rice processing

[0004] However, some rice will only be left with empty shells due to insects and other reasons. If it is simply distinguished by particle size, it cannot be graded well, and the quality of high-quality rice cannot be better improved. For this reason, we propose A screening and grading equipment for rice processing to solve the above problems
