Screening device for rice processing

Abstract

The invention relates to the technical field of rice processing, in particular to a screening device for rice processing. The screening device comprises a storage hopper, wherein sieved small-particle materials are mounted on the lower side of the storage hopper, sieved large-particle materials are mounted on one side of the sieved small-particle materials, a support frame is arranged on the lower side of the sieved large-particle materials, a filter residue collecting box is arranged on the lower side of the sieved small-particle material, an exhaust fan is installed at the upper end of the other side of the sieved small-particle material, a cloth cylinder filter bag is installed at the outer end of the exhaust fan, a hulling component is installed at the lower end of the interior of the storage hopper, a feeding net is installed at the joint of the storage hopper and the sieved small-particle material, and a screen is mounted at the upper end of the interior of the sieved small-particle material. The screening device is of a closed structure, dust floating in the screening process is avoided, circulating dust filtration is achieved, the dust filtration efficiency is high, rice before screening is hulled, the hulling structure is elastic mixing and stirring blades, and the integrity of the rice is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a screening device for rice processing. Background technique [0002] Rice grains are composed of husk, cortex, germ and endosperm. The purpose of rice processing is to separate the endosperm from other parts with the minimum degree of crushing to make rice with better eating quality, and remove the husk and The process of removing the cortex, after removing the husk, passes through the screening device to further improve the cleanliness of the rice. [0003] Chinese patent discloses a kind of paddy screening processing device, (authorization announcement number CN113019916A), this patented technology solves the problem that traditional screening device can't remove fine dust and debris by setting blower, conveying pipeline and collecting box, but above-mentioned device is too The sieve device is an open structure, and a lot of dust will be generated during the sieving p...

Problems solved by technology

[0003] Chinese patent discloses a kind of paddy screening processing device, (authorization announcement number CN113019916A), this patented technology solves the problem that traditional screening device can't remove fine dust and debris by setting blower, conveying pipeline and collecting box, but above-mentioned device is too The sieve device is an open structure, and a lot of dust will be generated during the sieving process, which is not conducive to the cleanliness of the work area. The above-mentioned device directly removes fine dust and debris through the blower, and the sieving stroke is short, which is not conducive to material screening. Completeness, generally there is no re-hulling structure of materials, rice husks will remain before sieving, which is not conducive to the subsequent processing of rice, and grains with rice husks cannot be screened smoothly
