A rice processing white rice grading and screening device

Abstract

The invention belongs to the technical field of rice processing, and specifically relates to a rice processing white rice grading and screening device, which includes a frame, a feeding hopper, a fixed box, a collecting box and a rotating box; the bottom of the feeding hopper is fixedly connected with a fixed box, and The hopper is connected to the inner space of the fixed box; the fixed box is designed in a ring; the rotating box is located in the collection box, and the diameter of the rotating box is smaller than the diameter of the collecting box; the second partition is slidably connected to the outer surface of the rotating box; Evenly arranged agitating plates; the outer surface of the rotating box is provided with uniformly arranged rice outlet holes, and the diameters of the rice outlet holes are designed to increase in order from left to right; the invention can effectively improve the firmness of the screen holes and drying surface The advanced screening equipment has the characteristics of small footprint, meticulous and clear rice screening and classification, and high screening efficiency. It further improves the purity of high-quality rice, reduces the content of mixed broken rice in rice, and refines the classification of rice grades while meeting customer needs for finished rice. .

Description

technical field [0001] The invention belongs to the technical field of rice processing, in particular to a grading and screening device for rice processing white rice. Background technique [0002] Rice, also known as rice, is a food made from rice after cleaning, husking, rice milling, and finished product finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. Rice is one of the staple foods of human beings. According to modern nutrition analysis, rice contains protein, fat, vitamin B1, A, E and more minerals. In terms of varieties, rice can be divided into japonica rice, indica rice and glutinous rice. [0003] During rice processing, due to the different particle sizes of rice and the fact that the rice will be broken and cracked during the hulling process, the processed rice needs to be graded by a screening device to separate rice of different grades and qualities.

Problems solved by technology

[0003] During rice processing, due to the different particle sizes of rice and the fact that the rice will be broken and cracked during the hulling process, the processed rice needs to be graded by a screening device to separate rice of different grades and qualities. The screening device in the technology can only achieve one-stage or two-stage screening at one time, and the strength of the screen hole and the firmness of the screen surface are poor, and the screening efficiency is low; while the high-efficiency screening equipment occupies a large area and is easy to use. The range is limited; the common rice screening equipment is not fine enough to screen, and the rice body is damaged due to the large friction between the rice and the equipment during the screening process. The finished rice is often mixed with some broken rice, which affects the quality of the finished rice.
