Rice processing polishing and screening device with bran powder removing mechanism

Abstract

The invention discloses a rice processing polishing and screening device with a bran powder removing mechanism, and relates to the technical field of rice processing. The rice processing polishing andscreening device with the bran powder removing mechanism aims to adjust polishing strength according to requirements. The rice processing polishing and screening device specifically comprises a mainbody. A polishing mechanism and a shelling mechanism are arranged in the main body. The polishing mechanism is located below the shelling mechanism. The polishing mechanism comprises a polishing motor, two polishing shafts and two polishing outer cylinders. The polishing motor is fixed to the outer wall of one side of the main body through screws. An output end of the polishing motor is rotationally connected to one end of a polishing shaft through a coupler. According to the rice processing polishing and screening device with the bran powder removing mechanism, by arranging an air bag with avalve core, the inflation state of the air bag can be controlled to control the friction force between the polishing outer cylinders and rice, so that the polishing strength is changed, and the practicability and the use flexibility are improved. By arranging elastic pieces, the firmness of connection between the polishing outer cylinders and the polishing shaft can be improved, the limiting effect on the polishing outer cylinders is achieved, and the phenomenon that the polishing outer cylinders slip is avoided to a large extent.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a polishing and screening device for rice processing with a bran powder removing mechanism. Background technique [0002] In the process of rice processing, in order to improve the eating taste and the appearance quality of rice, rice is often polished. Although most of the polishing devices currently used can achieve the purpose of polishing, they cannot adjust the polishing intensity according to the demand, resulting in polishing. less flexible. [0003] After searching, the Chinese patent application number is CN202010060581.3, which discloses a polishing device for rice processing and production. When the existing polishing device is in use, the powder attached to the surface of the rice grain is lifted up to cause pollution to the working environment. Problem, the following scheme is proposed, including the base, the top of the base is fixedly installed with a box,...

[0003] After searching, the Chinese patent application number is CN202010060581.3, which discloses a polishing device for rice processing and production. When the existing polishing device is in use, the powder attached to the surface of the rice grain is lifted up to cause pollution to the working environment. Problem, the following scheme is proposed, including the base, the top of the base is fixedly installed with a box, and the top of the box is fixed with a box cover, the top of the box cover is fixed with a feed hopper, and the inside of the box is fixed Lower polishing disc installed

The polishing device in the above patent has the following disadvantages: the polishing device cannot adjust the polishing force according to the demand, resulting in poor flexibility of polishing work
