Description
Technical field
The present invention relates to the screening techniques of brown rice, and the invention further relates to the screening plants of brown rice.
Background technique
The rice for only getting rid of rice husk is called brown rice.Brown rice contains plumule, and the nutritive value of plumule is very high.In order to
The plumule that store the microelement of human body needs is retained, needs to carry out special processing to brown rice.In process, if
The brown rice same length of same processing batch, can bring many conveniences to process.In addition occurs a kind of pursuit now
The people of green consumption and full nutrition theory, their steamed rices or cooks congee without highed milled rice, directly uses brown rice.In the market in order to
Meet the consumption idea of this groups of people, the brown rice of direct marketing exquisiteness packaging also can in sale if brown rice granularity uniformity
Improve grade.But currently without batch production, the method and apparatus screened according to the length of brown rice on a large scale.
Summary of the invention
The present invention is to solve the problems, such as to provide one kind there are currently no the method and apparatus that the length according to brown rice is screened
Brown rice length screening technique.
It is included the following steps: one, brown rice is allowed to be inserted into the sieve pore 1-1 of sieve plate 1 with upright state, the lower end of brown rice
It withstands on the upper surface of bottom plate 2；N number of sieve pore 1-1 is evenly distributed on the sieve plate 1, the bottom plate 2 and sieve plate 1 positioned at 1 lower section of sieve plate are flat
Row and the two tiling setting；N is the positive integer more than or equal to 10 and less than 2000；Two, length is greater than between sieve plate 1 and bottom plate 2
The brown rice of clearance D is kept upright state, and the brown rice that length is less than clearance D is poured on the upper surface of bottom plate 2；Three, sieve is reduced
Clearance D between plate 1 and bottom plate 2；Four, it allows between sieve plate 1 and bottom plate 2 and translation occurs, be poured on rough on the upper surface of bottom plate 2
The grain of rice still remains on bottom plate 2, and the brown rice being inserted in sieve pore 1-1 leaves the upper table of bottom plate 2 with the translation of sieve plate 1
Face.
The present invention also provides brown rice apparatus for length screening, it includes sieve plate 1, bottom plate 2, height adjusting system and horizontal position
Shifting system is uniformly provided with N number of sieve pore 1-1 on the plate body surface of sieve plate 1, the bottom plate 2 positioned at 1 lower section of sieve plate it is parallel with sieve plate 1 and
The two tiling setting, N are positive integer more than or equal to 10 and less than 2000, height adjusting system setting sieve plate 1 and bottom plate 2 it
Between adjust clearance D between sieve plate 1 and bottom plate 2, horizontal displacement system is arranged between sieve plate 1 and bottom plate 2 so that the two is arranged
Between be the upper and lower corresponding position relationship either positional relationship that is staggered up and down.
Methods and apparatus of the present invention can be such that longer brown rice and shorter brown rice separates two different positions
It sets, completes the screening work according to brown rice grain length.The present invention can be realized using automatic machines and equipment, be solved existing
Technology is unable to batch production, the problem of being screened on a large scale according to the length of brown rice.
