Screening system and process method for double sorting of grain particles

Abstract

The invention discloses a screening system and process method for double sorting of grain particles, and relates to the technical field of grain processing. A rotary sorting mechanism capable of discharging at intervals is arranged in a dust collection mechanism, a bidirectional sorting mechanism is fixed to the bottom of the dust collection mechanism, and anti-blocking material collecting mechanisms are connected to the two sides of the bidirectional sorting mechanism correspondingly; the two-way sorting mechanism comprises a first collection hopper, two inclined surface material guide tables are symmetrically arranged at the bottom of a partition plate in the first collection hopper, and two first material gathering plates are fixed to the surfaces of the inclined surface material guide tables; a first sieve hole structure located on the inner sides of the two first material gathering plates is arranged on the surface of the inclined face material guiding table. Through the design of the second sieve pore structure, the first sieve pore structure, the inclined surface material guide table and the inclined surface material guide plate, effective separation of complete large-particle grains and broken-particle grains in grain particles can be achieved, and through the sorting mode that small-particle broken grains are discharged firstly and then the large-particle grains are discharged, the grain separation efficiency is improved; and the sorting effect of the crushed grain particles in the grain particles is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of grain processing, and in particular relates to a screening system and a process method for double sorting of grain particles. Background technique [0002] Grain refers to the general term of various plant seeds used as staple food in cooking food, and it can also be generally referred to as grain. After the grain particles are processed and shelled, the coarser grain particles are obtained, and the coarse grain particles contain a part of broken small grain grains. And grain husk debris, so it is necessary to sort and process the coarse grain grains after shelling to obtain grain grains that remove debris and broken grain grains. [0003] After retrieval, the Chinese patent number is CN213855606U, a kind of grain particle sorting equipment, which discloses the specific technology of grain grain double sorting, which solves the problem that the existing grain sorting equipment can only sieve the grain, an...

Problems solved by technology

[0003] After retrieval, the Chinese patent number is CN213855606U, a kind of grain particle sorting equipment, which discloses the specific technology of grain grain double sorting, which solves the problem that the existing grain sorting equipment can only sieve the grain, and cannot At the same time, the debris and dust in the grain are cleaned, so secondary work is required to clean the debris and dust in the grain, which makes the work too troublesome

[0004] However, the inventors of the present application found that the above-mentioned technology still has the following disadvantages during the implementation of specific embodiments of the present invention: (1) the above-mentioned grain particle sorting equipment does not disclose the intermittent feeding structure of grain particles, At the same time, the technology of primary sorting of crushed particles in the intermittent feeding process of grain particles is not disclosed; (2) the above-mentioned grain particle sorting equipment does not disclose the specific method of fast dredging when the flow channel of grain particles is blocked without causing the grain particles to break technology
