Description
Technical Field
The invention belongs to the technical field of rice screening, and particularly relates to a rapid screening method for brown rice containing miscellaneous rice.
Background
The screening is a process of dividing the mixed waste of particles with different particle sizes into two or more groups of particles by using one or more than one screen surface. The screening usually has two kinds of operations of wet separation and dry separation, and the screening of solid waste often selects dry separation for use, can go on simultaneously by a plurality of sifters during the screening moreover. The screening process can be divided into two processes of material layering and fine particle screening, wherein the fine particle screening is used for separation;
in order to improve the quality of rice, a rapid screening method for the brown rice with miscellaneous rice is provided.
Disclosure of Invention
The invention mainly aims to provide a method for rapidly screening brown rice containing miscellaneous rice, which can effectively solve the problems in the background technology.
In order to achieve the purpose, the invention adopts the technical scheme that:
a rapid screening method for brown rice containing miscellaneous rice comprises the following steps:
step one, putting rice to be screened into an air separator, blowing the miscellaneous rice brown rice with light dust shrivelled, rice husks and the miscellaneous rice brown rice by the air separator, and remaining rice to be screened;
step two, putting the rice left in the step one into a sieve for screening, separating the rice according to different sizes and shapes of the rice, and removing impurities by using the sieve to obtain relatively pure rice;
step three, putting the rice after the moisture removal into a rice huller, hulling the rice, and separating the miscellaneous rice in the hulled brown rice mixture from the unhulled rice;
step four, putting the separated miscellaneous rice into a thickness classifier to remove immature grains and broken grains;
putting the classified mixed rice into a rice mill for husking and whitening;
and sixthly, putting the screened complete granules into a color sorter to remove the abnormal granules, and finally obtaining the pure rice to achieve the aim of removing the impurity rice and the brown rice.
Preferably, the air separator is of FX-12 type.
Preferably, the mesh of the sieve has a circular shape, a square shape, a rectangular shape and a triangular shape.
Preferably, the air separator consists of a coarse crushing device, a fine crushing device, a wind power conveying device and the like, and the purpose of crushing is achieved by utilizing a high-speed impact mode.
Preferably, the feeding granularity of the winnowing machine is 10-15mm, the discharging granularity is 20-325 meshes, and the yield is 3-200 kg/h.
Preferably, the sieve has a particle size of 20 to 80 mesh.
Compared with the prior art, the invention has the following beneficial effects: the invention relates to a rapid screening method for miscellaneous rice brown rice, which improves the quality of screened rice through multi-stage screening procedures such as winnowing, screening, separating, color sorting and the like, and meanwhile, the screening method is simple and practical and has practicability.
