High-efficiecy dust removing, drying and screening device for grain

Abstract

The invention discloses a high-efficiency dust removing, drying and screening device for grain. The device comprises a shell, supporting legs are symmetrically arranged on the left side and the rightside of the bottom of the shell; a feeding hopper is arranged in the middle position of the top of the shell; a flow guide bin is arranged in the middle part in the shell; the flow guide bin is conical; the bottom plate of the flow guide bin is shaped like an upward-protruding cone; the vertex of the flow guide bin is right opposite to the center of the feeding hopper; vertical rods are symmetrically arranged on the left side and the right side of the flow guide bin; the top end of each vertical rod is welded to the inner top of the shell; screens are symmetrically arranged on the inner wallsof the left side and the right side of the portion, below the flow guide bin, of the shell; the two screens are inclined to the position below the middle of the two screens; and a vertical sleeve is arranged between the two screens. According to the high-efficiencydust removing, drying and screening device for grain, the structure is novel and ingenious in arrangement, rapid air drying and dust removing are achieved, and the drying efficiency and the dust removing quality are greatly improved; in addition, a screening mechanism is ingeniously arranged, thus repeated screening and quick screening can be realized at the same time, and screening is thorough; and materials can be conveniently discharged.

Description

technical field [0001] The invention relates to the technical field of food processing equipment, in particular to a high-efficiency grain dust removal, drying and screening device. Background technique [0002] "Grain" covers a wide range, including rice, wheat, millet, soybeans, etc. and other miscellaneous grains. Cereals include rice, wheat, millet, soybeans, etc., mainly plant seeds and fruits. It is the traditional staple food of many Asian people. Grains contain protein Between 8-12%, because the protein content of the outer layer of the grain is higher than that of the inner layer, the refined rice and flour have a lower protein content than the rough rice and noodles due to excessive removal of the outer skin. For example, whole grain The physiological value of rice protein is 72.7, while the protein physiological value of polished white rice is reduced to 66.2. The content of lysine, phenylalanine and methionine in cereal protein is low. Especially the lysine in mi...

Problems solved by technology

[0003] Grains need to be dried and stored after harvesting. However, traditional drying equipment has rigid mechanisms, single functions, and low drying efficiency.
