Abstract

The invention discloses a kind of grain screening method of grain gas solid separation of food processing technology field, this method is as follows:S1:Dust-laden cereal is delivered to by import in settler by Turo pump;S2:After the by-pass filtration web plate being arranged on the sedimentation pipeline built in settler, cereal is filtered dust-laden cereal by by-pass filtration web plate, and is dropped into inside expansion chamber by delivery pipe;S3:Subsequent cereal passes through secondary filtration web plate and three-stage filtration web plate respectively, respectively will be in the cereal gravitational settling to expansion chamber corresponding thereto of different-grain diameter;S4:After three-stage filtration, the little particle impurity that cereal is deposited in expansion chamber, and is adulterated in cereal is then exported with air-flow by outlet, realizes the screening to cereal, and the present invention is easy to operate, and processing procedure is efficient, improves the quality of cereal reprocessing.

Description

A kind of grain screening method of grain gas solid separation
Technical field
The invention discloses a kind of grain screening method of grain gas solid separation, specially foods processing technique is led Domain.
Background technology
Cereal -- the range covered is wider, including rice, wheat, millet, soybean etc. and other coarse cereals.Cereal includes big Rice, wheat, millet, soybean etc., mainly vegetable seeds and fruit.It is traditional staple food of many Asia people.Cereal, not merely Refer to the seed of grass more definitely can be broadly divided into three classes in China:Cereal:Including rice class (long-grained nonglutinous rice, japonica rice, Nuo Rice), wheat (wheat, barley, oat, rye), corn, sorghum, grain, broomcorn millet, glutinous millet, buckwheat etc.;Beans bean class:Including soybean, silkworm Beans, pea, mung bean, red bean, kidney bean etc.;Potato:It is also referred to as sweet potato or sweet potato, potato, Chinese yam, taro, cassava etc. including sweet potato. Cereal after harvesting, needs cereal fringe being sent into thresing machine, and in threshing course, cereal-granules are in contact with threshing unit, Cereal is set to be detached from cereal fringe, but cereal adulterates more impurity during threshing, this is just needed these impurity point From.For this purpose, we have proposed a kind of grain screening methods of grain gas solid separation to come into operation, to solve the above problems.
Invention content
The purpose of the present invention is to provide a kind of grain screening methods of grain gas solid separation, to solve above-mentioned background The problem of being proposed in technology.
To achieve the above object, the present invention provides the following technical solutions:A kind of grain screening of grain gas solid separation Method, this method are as follows:
S1:Dust-laden cereal is delivered to by import in settler by Turo pump;
S2:Dust-laden cereal is after the by-pass filtration web plate being arranged on the sedimentation pipeline built in settler, and cereal is by level-one Screen pack filters, and is dropped into inside expansion chamber by delivery pipe;
S3:Subsequent cereal passes through secondary filtration web plate and three-stage filtration web plate respectively, respectively by the cereal weight of different-grain diameter Power is deposited in expansion chamber corresponding thereto;
S4:After three-stage filtration, cereal is deposited in expansion chamber, and the little particle impurity adulterated in cereal is then with gas Stream is exported by outlet, realizes the screening to cereal.
Preferably, the pore size filter of the by-pass filtration web plate, secondary filtration web plate and three-stage filtration web plate reduces successively.
Preferably, the by-pass filtration web plate, secondary filtration web plate and the pore size filter on three-stage filtration web plate and cereal Gradation grain size be adapted.
Preferably, the upper and lower ends of the delivery pipe are connected with sedimentation pipeline and expansion chamber respectively.
Preferably, the gas flow rate in the sedimentation pipeline in the settler is 12--15m/s.
Preferably, the interval between the by-pass filtration web plate, secondary filtration web plate and three-stage filtration web plate is 5-- 6cm。
Compared with prior art, the beneficial effects of the invention are as follows:The present invention is detached by three-stage filtration, makes different-grain diameter Cereal-granules are fallen in expansion chamber, and the smaller particle impurity adulterated in cereal realizes the gas-solid to cereal then as air-flow exports Separation ensure that the cleanliness factor of cereal, and the present invention is easy to operate, and processing procedure is efficient, improves the quality of cereal reprocessing.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure:1 settler, 2 imports, 3 outlets, 4 sedimentation pipelines, 5 by-pass filtration web plates, 6 secondary filtration web plates, 7 three-levels Screen pack, 8 delivery pipes, 9 expansion chambers.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution:A kind of grain screening method of grain gas solid separation, This method is as follows:
S1:Dust-laden cereal is delivered to by import 2 in settler 1 by Turo pump;
S2:Dust-laden cereal is after the by-pass filtration web plate 5 being arranged on the sedimentation pipeline 4 built in settler 1, and cereal is by one Grade screen pack 5 filters, and is dropped into inside expansion chamber 9 by delivery pipe 8;
S3:Subsequent cereal passes through secondary filtration web plate 6 and three-stage filtration web plate 7 respectively, respectively by the cereal of different-grain diameter In gravitational settling to expansion chamber 9 corresponding thereto;
S4:After three-stage filtration, cereal is deposited in expansion chamber 9, and the little particle impurity adulterated in cereal then with Air-flow realizes the screening to cereal by 3 output of outlet.
Wherein, the pore size filter of the by-pass filtration web plate 5, secondary filtration web plate 6 and three-stage filtration web plate 7 contracts successively It is small, the by-pass filtration web plate 5, secondary filtration web plate 6 and pore size filter and cereal on three-stage filtration web plate 7 gradation Grain size is adapted, and the upper and lower ends of the delivery pipe 8 are connected with sedimentation pipeline 4 and expansion chamber 9 respectively, in the settler 1 Sedimentation pipeline 4 in gas flow rate be 12--15m/s, the by-pass filtration web plate 5, secondary filtration web plate 6 and three-stage filtration Interval between web plate 7 is 5--6cm.
Invention by three-stage filtration separation, so that the cereal-granules of different-grain diameter is fallen in expansion chamber 9, adulterated in cereal compared with Little particle impurity realizes the gas solid separation to cereal then as air-flow exports, and ensure that the cleanliness factor of cereal, the present invention operate letter Single, processing procedure is efficient, improves the quality of cereal reprocessing.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace And modification, the scope of the present invention is defined by the appended.
