A kind of polished rice milling method

Abstract

The invention discloses a fine rice grinding method which comprises the following steps that (1) grain is rolled into the rice milling device through a feeding hopper, and crushed, the rice precisionis adjusted in real time according to the grain amount by using an accuracy adjusting device according to the grain amount, the grain is milled into rice grains, broken rice and mink, and at the sametime, during the rolling process, the negative pressure suction device is used to separate the milled material, and some broken rice and part of the mink are discharged, and the remaining broken riceand mink are discharged with the rice grain; and (2) the outflowing rice grain is diverted, causing the rice grain to flow out according to the set path, and the rice grain twice is separated during the outflow process by using the negative pressure suction air outlet device, so that the remaining broken rice and mink are removed from the rice grain, and the fine rice is obtained. According to thefine rice grinding method, the rice precision according to the amount of grain in the rice milling process is accurately adjusted, the broken rice rate is reduced and the rice yield rate is increased; and the broken rice and the skin are effectively separated from the rice grain, the clean rice grain is thoroughly selected by winnowing, and the purpose of producing polished rice is achieved.

Description

technical field [0001] The invention relates to the technical field of rice milling, in particular to a method for milling polished rice. Background technique [0002] my country has a vast rural area, and its agricultural production is dominated by rice planting, known as the "big rice planting country". And in most areas of our country, rice is the staple food. Rice is made by milling, hulling, sifting and sorting the grains. In the vast rural areas, the traditional rice milling operation is to send the grains to the processing point for centralized shelling, and then wind selection to remove the bran to obtain rice. However, this traditional rice milling machine is bulky, expensive, and noisy. The rice produced has a large amount of broken rice, poor rice quality, and a low rice yield. [0003] In order to improve the quality of rice milling, recently, some small rice milling machines have appeared one after another, which are small in size, light in weight and low in p...

AI Technical Summary

Problems solved by technology

[0004] 1. The patent relies entirely on operating experience to adjust the rice precision, but it cannot be precisely controlled, which will easily cause excessive load on the rice mill, high rice temperature, and rice containing grains that are not cleaned; and bran will remain in the finished rice And small broken rice, can not be completely separated clean

[0005] 2. The bearing body in this patent is limited by its shape and structure. It can only be cast by ordinary sand casting with high energy consumption. The surface roughness of the casting is poor, which affects the poor appearance quality and is prone to casting defects

[0007] 1. The structure of the fine-tuning device is inconvenient to install and maintain, the exposed structure is too simple, there are potential safety hazards during use, and there is no sense of quality

[0008] 2. Due to the high-speed rotation of the rice milling spindle, the parts set on the shaft are easy to cause wear and tear, and the reliability is poor; and the dust generated during the processing will adhere to the groove equipped with balls, which will easily cause inflexible adjustment and even failure of adjustment

[0009] 3. Limited by the structure, the adjustment range is limited when adjusting the accuracy, the gear span is large, and there are gaps and gaps. It is impossible to intuitively and accurately adjust the rice output pressure, and the quality of rice milling is low.
