Color sorter for rice

Abstract

The invention discloses a color sorter for rice. The color sorter comprises a machine body, a feed hopper, a vibrating feeder, a rice sliding channel, a light source, a background plate, a CCD lens, an electronic optical analysis meter, an electronic airflow ejector and a discharge bin are installed in the machine body, the discharge bin comprises a first-grade bin collecting high-quality rice and a second-grade bin collecting poor-quality rice, a speed reducing mechanism and a vibrating screen are arranged inside the first-grade bin, the speed reducing mechanism comprises a receiving hopper and a speed reducing channel, the receiving hopper communicates with the speed reducing channel and is located below the rice sliding channel to receive the high-quality rice, speed reducing plates are arranged inside the speed reducing channel, and the speed reducing channel is located right above the vibrating screen and is used for conveying the high-quality rice to the vibrating screen. According to the color sorter, a screening machine adopted before color sorting is eliminated innovatively, a screening mechanism is designed inside the color sorter, the rice undergoes color sorting firstly to screen out the poor-quality rice and the high-quality rice, then the high-quality rice is screened by size, and therefore color sorting and screening are combined, and the working pressure of the screening step is lowered.

Description

technical field [0001] The invention belongs to the technical field of food production, and in particular relates to a rice color sorter. Background technique [0002] Rice color sorting is a process of screening heterochromatic particles and impurities in rice by using CCD optical imaging technology. After the rice material arrives at the processing site, it is necessary to determine the proportion of different-colored particles and impurities, that is, the impurity rate. The impurity rate in the rice material directly affects the color sorting accuracy of the rice color sorter. The higher the impurity rate, the color sorter The lower the precision, the worse the effect. Most colors on the market [0003] When the impurity rate of the sorter is 2%, the color sorting accuracy can basically reach 99.99%. Except that the impurity content will affect the color sorting effect of the color sorter, [0004] The output per unit time is also one of the key factors. The output is...
