Coarse filtration system for rice fine processing

Abstract

The invention discloses a coarse filtration system for rice fine processing in the technical field of grain processing. The coarse filtration system comprises a feeding bin, a screening bin and a discharging bin which are sequentially connected from top to bottom, wherein a first winnowing chamber and a second winnowing chamber which are arranged side by side in a left-and-right mode and communicate with each other are arranged in the screening chamber; two sets of roller winnowing mechanisms which are spaced and are aligned vertically are arranged in the first winnowing chamber; each roller winnowing mechanism comprises two left-and-right parallel rollers which are rotatably connected with the first winnowing chamber and driven by a motor; a plurality of first fans annularly arranged arearranged in each roller; a plurality of ventilation holes are formed in each roller; second fans for horizontally blowing air are arranged above the rollers; two third fans are arranged in the secondwinnowing chamber; and a rice discharging chamber and a bran discharging chamber are arranged in the discharging bin. According to the coarse filtration system for rice fine processing, through uniquestructural design, thorough separation of the rice from bran can be realized, and the processing of the rice in the later stage and the collection of the bran can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and in particular relates to a coarse filter system for rice finishing. Background technique [0002] Rice (Rice) is a finished product made of rice after cleaning, husking, rice milling, and finished product finishing. Rice is the 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. It is the main food of the southern people. [0003] After the rice is cleaned and husked, white rice grains are obtained. At this time, the rice grains are rough, commonly known as "brown rice". Brown rice is used for cooking. The cooking time is long, the color is dark, the viscosity is poor, and the taste is not good. Because the cortex of brown rice is complete, water absorption and expansion are not strong, resulting in poor eating quality. The...
