Multi-effect husked rice separation equipment and method

Abstract

The multi-effect husked rice separation equipment comprises a screening box and a control box connected to one side of the screening box, and a feeding box communicating with the interior of the screening box is installed at the top of the screening box; a feeding mechanism is connected to the top of the feeding box, a plurality of trapezoidal boxes used for preliminarily screening materials are arranged in the feeding box, an impurity discharging box covers the outer side of the feeding box, and a dust separating mechanism used for extracting dust in the impurity discharging box is arranged on one side of the screening box; when brown rice materials are screened, the stroke of the materials can be prolonged, when the materials impact and flow, part of impurities are removed through falling of the materials, preliminary screening is completed, the screening mechanism can conduct secondary screening on the materials, and meanwhile when the materials flow in the feeding box and the screening box, the screening efficiency is greatly improved. The flying dust can be timely adsorbed and treated by the dust separation mechanism, so that the dust is separated and collected, and the treated clean air can be reused to make hot air to dry the separated brown rice.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a multi-effect paddy separation device and method. Background technique [0002] During rice processing, the paddy hull is removed to make brown rice. The brown rice contains part of the broken rice and rice husk, which need to be separated to reduce the sundries in the brown rice to facilitate subsequent processing. [0003] The existing patent notification number is CN112371504B, which discloses a separable and automatic screening dust removal device for rice processing. When rice is input from the feed port, the blower first separates the dust from the rice, and the primary separation device is used with the use of a scraper. The dust is collected and cleaned, and the sundries in the rice can be separated through the secondary separation equipment, and the rice without dust and rice husk is sucked to the position of the secondary separation equipment by negative pressu...

AI Technical Summary

Problems solved by technology

[0004] However, in the process of screening and separating rice, the above-mentioned device has a short material dust removal stroke, and cannot effectively separate the dust and sundries in the rice during the process of material falling and flowing, and needs to be improved.
