A kind of impurity removal process for rice

Abstract

The invention discloses an impurity removal technology for rice. The impurity removal technology comprises the following steps that unhusked rice is put into an impurity removal machine to remove impurities, and then laid in a drying room, after drying, cooling is conducted to room temperature, the unhusked rice which is cooled to room temperature is put into a rice husking machine to remove ricehusks, and the husked rice is put into an impurity removal device to complete impurity removal. Through a filter cone, recovery of the rice husks is completed, because the rice is laid, the rice huskscan be removed to the greatest extent through the work of a husk collecting machine, the whole husking mechanism can thoroughly clear the rice husks mixed in the rice away, moldy rice in the rice isremoved, the situation that after the rice goes moldy, aflatoxin is possibly generated to be eaten by people is avoided, and the body health of people is ensured. After broken rice in the rice is removed, the rice further can be classified, a threaded screw is rotated to move in a threaded sleeve base so as to drive the movable roller to move, so that the gap between a fixed roller and a movable roller is adjusted, and automatic adjustment is easily conducted according to different varieties of rice and classifying standards.

Description

technical field [0001] The invention relates to the field of rice production, in particular to a rice impurity removal process. Background technique [0002] Rice is the daily staple food of people, broken rice, imperfect grains, maximum limit of impurities, pesticide residues, moisture, yellow grain rice, mixed, cadmium, arsenic, lead, mercury and other testing items are important indicators for rice detection; If the impurities in the rice are not removed, the impurities in the subsequent rice will have a certain impact on the health of the people and seriously endanger people's health. [0003] The existing rice impurity removal process only filters the rice sand and gravel through the screening device to remove the sand and gravel particles in the rice. In the process of rice milling and husking, some rice husks will be mixed in it, so it cannot be thoroughly cleaned. At the same time, rice may become moldy due to a series of reasons during harvesting, transportation an...

Problems solved by technology

[0004] The purpose of the present invention is to provide a rice impurity removal process. In order to overcome the above-mentioned existing rice impurity removal process, only the rice gravel is filtered through a screening device to remove the sand and gravel particles in the rice. Some of the rice husks will be mixed in it, and it cannot be completely removed; at the same time, rice may become moldy due to a series of reasons during harvesting, transportation and storage, and moldy rice may produce aflatoxin , Aflatoxin is a kind of toxic substance. When the mildewed rice is eaten in the future, it will produce toxicity and seriously endanger people's health; finally, a large amount of broken rice will be produced during the production process of rice, and the broken rice will be mixed with the whole rice to cause subsequent The rice quality problem, the broken rice becomes the mixed impurity in the rice, it is necessary to remove the broken rice to ensure the technical problem of the quality of the rice
