Rice preparation and processing precision standard grading classificator and grading selection process

Abstract

The invention relates to a rice preparation and processing precision standard grading classificator and grading selection process. The rice preparation and processing precision standard grading classificator comprises a fixed base, a first mounting table, a second mounting table, a mounting cylinder and a centrifugal screening device, the first mounting table is fixed to the left side of the upperend of the fixed base, and the second mounting table is mounted in the middle of the upper end of the fixed base; the upper ends of the first mounting table and the second mounting table are connected through the mounting cylinder, and the centrifugal screening device is arranged at the right side of the upper end of the fixed base; and a rotating motor drives a rotating roller to rotate, then small broken rice and impurities are separated from whole rice through centrifugal force, and the grading efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice preparation and processing precision standard classification and selection machine and a classification and selection process. Background technique [0002] The existing rice harvesting methods usually use harvesting machines to harvest the rice, which often mixes some poor-quality rice. At the same time, the rice may be broken during the harvesting process, and some rice may be damaged during the rice transportation process. Mixed with impurities. In the process of rice processing, it is usually necessary to clean up poor quality rice, broken rice and impurities in time, otherwise defective rice, broken rice and impurities will enter the subsequent processing stage, resulting in a decline in the overall quality of rice. [0003] At present, when rice is graded and processed, there are usually the following defects: 1. The traditional rice processing and screening...

Problems solved by technology

[0005] The present invention can solve the traditional rice processing and sieving treatment method. Manual sieving is often used, and smaller impurities and broken rice are sieved out by shaking the sieving frame up and down. This grading and sieving method often results in The sieving frame shakes up and down, causing the rice to collide and produce more broken rice, and the efficiency of manual sieving is low, and the quality of sieving cannot be guaranteed; the traditional rice processing and sieving method is used to classify and sieve rice At the same time, due to insufficient dispersion, some impurities and broken rice are deep in the rice pile, and it is difficult to carry out difficult problems such as grading and screening.
