Coarse filtering system for rice finish processing

Abstract

The application discloses a coarse filtering system for rice finish processing and belongs to the technical field of grain processing. The coarse filtering system comprises a feeding bin, a screening bin and a discharging bin connected from top to bottom in sequence. A first winnowing chamber and a second winnowing chamber which are arranged from left side to right side and communicated with each other are arranged in the screening bin. Two roller winnowing mechanisms arranged at an interval and aligned up to down are arranged in the first winnowing chamber. Each roller winnowing mechanism comprises two rollers arranged left to right in parallel; the two rollers are both connected with the first winnowing chamber rotationally and driven by motors; a plurality of first fans in circular arrangement are arranged in the rollers; the rollers are provided with a plurality vent holes; secondary fans with horizontal air discharging are arranged above the rollers. Two third fans are arranged in the second winnowing chamber. A rice discharging chamber and a bran discharging chamber are arranged in the discharging bin. By the innovative structural design, thorough separation of rice and bran is achieved, which brings convenience to rice processing and bran collecting at the later period.

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...
