Husked rice separation and color sorting system

Abstract

The invention discloses a husked rice separation and color sorting system. The system comprises two groups of perspective detection pairs, an air injection device and a signal processor, wherein the two groups of perspective detection pairs are arranged at a material outlet of a material and correspondingly include a first perspective detection pair formed by an infrared light source I and a camera II, a second perspective detection pair formed by the infrared light source II and the camera I; the camera I and the camera II shoot the same material at the same target position, and the materialat the target position is positioned on a scattering light path of the infrared light source I and the infrared light source II at the same time; the signal output ends of the camera I and the cameraII are connected with the signal input end of a signal processor; and the signal processor is in control connection with an air injection valve of an air injection device. According to the system, thedensity of the materials is detected through dual-frequency perspective, the materials are sorted according to different densities of the materials, and the sorting with the same color, the same water content and the same shape is realized.

Description

technical field [0001] The invention relates to the technical field of color sorting machines, in particular to a color sorting system for rice and rough separation. Background technique [0002] The color sorter is the sorting equipment with the highest technical content in the field of agricultural material sorting. It is mainly used for the precise sorting of agricultural materials and is the final guarantee technology for the apparent quality of agricultural products. The level of color sorting technology directly affects the quality of products. For example, the rice color sorter is the last sorting equipment in rice production, and it is necessary to remove all impurities, mildewed rice, diseased rice, etc. in the rice. It is a rice product quality assurance technology. With the development of color sorting technology, the application field is also expanding, gradually extending from detection and sorting to sorting equipment in the process of processing and producti...

AI Technical Summary

Problems solved by technology

When the color of the material is the same and the moisture content is the same, the traditional color sorter basically cannot distinguish

The color, moisture content and shape of paddy, chaff, and hulled brown rice are basically the same, so traditional color sorters cannot effectively distinguish millet, chaff, and brown rice

Unable to effectively remove the millet and chaff contained in brown rice

[0004] Traditional color sorting technology cannot distinguish materials with the same color, moisture content and shape

Paddy, chaff, and hulled brown rice are basically the same in color, moisture content and shape, so traditional color sorters cannot effectively remove the millet and chaff contained in brown rice.
