Color sorting equipment for fine processing of rice

Abstract

The invention discloses a color sorting device for rice finishing, comprising a frame, a feeding hopper installed on the frame, and a vibrating feeding device, an air separation dust removal device, and a flow material installed on the frame. A groove, a photoelectric detection sensor, an air ejector and a discharge channel, the air separation and dust removal device includes an inclined material guide channel and a material distribution channel connected with the right side of the material guide channel, and the left side of the material guide channel is connected with The air inlet channel corresponding to the material distribution channel is provided with an air leakage screen at the connection between the air inlet channel and the material guide channel, a blower corresponding to the air leakage screen is installed in the air inlet channel, and a dust removal screen is installed in the material distribution channel. The lower end of the distributing channel is located on the left side of the dust-removing screen and is connected with a discharging channel. The present invention has a reasonable structure design, can effectively remove shriveled or unfilled rice grains, improves the overall quality of the rice, removes the dust in the rice thoroughly, and is conducive to prolonging the Equipment life.

Description

technical field [0001] The invention relates to the technical field of rice color sorting equipment, in particular to a kind of color sorting equipment for rice finishing. Background technique [0002] The core equipment of the rice color sorting technology is the color sorter, and its working principle is: the selected white rice is delivered to each sorting channel from the feeding hopper through the electromagnet vibrating feeder and then falls down into the photoelectric detector. The spectral frequency bands determined by normal high-quality rice grains are input into the color palette, while the spectral bands of colored grains are different from them. The reflection of rice grains to light and the reflection of the reflective screen are compared in the electronic mirror. If there is a difference in color, it will enter the computer through photoelectric conversion, and the signal will be amplified by the amplifier. If there are color particles, the signal exceeds the...

AI Technical Summary

Problems solved by technology

[0003] When sorting particles inside the existing color sorter, the dust between the particles will rise up, and the dust will adhere to the internal parts of the color sorter, which seriously affects the service life of the color sorter; in addition, the color sorter The machine can only remove colored rice grains, but cannot remove shriveled or unfulfilled rice grains, which reduces the overall quality of rice
