Rice processing screening equipment

Abstract

The invention discloses a rice processing and screening equipment, which comprises a screening room and a dust removal box. The upper end of the side wall of the screening room is provided with an air suction port, and the air suction port is connected with the lower end of the side wall of the dust removal box through a fan. The screening room includes a primary effect screen, The medium-effect screen and the top cover on the top of the screening chamber, the top cover has a feed inlet, the primary-effect screen is located above the medium-effect screen, and the bottom of the primary-effect screen, the medium-effect screen and the screening room are all along the rice The sliding direction is inclined downward; the top cover also has several magnets, which are parallel to each other and have equal spacing. The lower surface of the top cover is provided with grooves matching the magnets. The inclination direction gradually inclines from the bottom surface of the groove to the top surface toward the center of the groove. The invention not only has high screening efficiency, greatly reduces manpower and production cost, but also can remove stones and metal scraps to ensure the safety of rice consumption.

Description

technical field [0001] The invention belongs to the technical field of rice processing equipment, in particular to a rice processing and screening equipment. Background technique [0002] In the process of rice processing, due to various reasons, the size of the processed rice particles is not exactly the same, there will be some larger particles, some smaller particles, and there will be a certain amount of dust, but in the sales process , The price of rice with large grains and rice with small grains is completely different, and if the grains of rice sold are uneven in size, or even mixed with dust, the quality and sales price of rice will be seriously reduced. Therefore, in order to improve the commercial value of the product, To obtain better quality rice, at the end of rice processing, it is necessary to manually screen large-grained rice and small-grained rice, which is time-consuming and labor-intensive. The rice will also be mixed with some metal objects and stones, ...

[0002] In the process of rice processing, due to various reasons, the size of the processed rice particles is not exactly the same, there will be some larger particles, some smaller particles, and there will be a certain amount of dust, but in the sales process , The price of rice with large grains and rice with small grains is completely different, and if the grains of rice sold are uneven in size, or even mixed with dust, the quality and sales price of rice will be seriously reduced. Therefore, in order to improve the commercial value of the product, To obtain better quality rice, at the end of rice processing, it is necessary to manually screen large-grained rice and small-grained rice, which is time-consuming and labor-intensive. The rice will also be mixed with some metal objects and stones, which are accidentally mixed into the rice during the screening process. In addition, the dust in the rice not only pollutes the working environment, but even affects the health of the staff.
