Problems solved by technology

[0002] Most of the existing rice mills use horizontal hexagonal rice sieves. The whitening pressure is easy to control, the technology is mature, and the cost is low. For long-grain indica rice, it is easy to break, and there are many broken rice. The germ end is easy to be stressed, and the germ is easy to fall off or even disappear.

Embodiment Construction

[0018] The hexagonal rice sieve is a two-lobed structure, and the center side is fixed with screws.

[0019] 40-55% of the inner wall surface of the hexagonal rice sieve is file tooth pattern from coarse to fine, from deep to shallow, which strengthens grinding and roughening.

[0020] The middle 35-45% is a flat surface, which is convenient for the grain to roll and frictionally polish itself.

[0021] The lower 15-20% is equipped with symmetrical or semi-open hinges to control the whitening pressure and rice output speed.

[0022] The 1 / 2 of both sides of the hinge is equipped with 300% high-strength food-grade silica gel, which plays the role of rebound closure.

[0023] The bottom of the hinge is connected to the static friction double-acting cylinder.

[0024] Choose 201#, 304# stainless steel plate, thickness 1.2-1.5mm, punch 15×1.5 long strip holes.

[0025] The gear chopping machine chops out the tooth pattern from thick to fine and from deep to shallow in turn.

Abstract

The invention discloses a clamshell type whole grain rice sieve. The rice sieve is characterized in that two pieces of the rice sieve are fixedly used, and middle side seams are fixed by screws. Filing tooth lines from deep to shallow and from thick to thin are distributed on the inner layer, the middle layer is a smooth flat plate, self-rolling friction polishing of grain is facilitated, and a clamshell type hinge is arranged at the tail end. The hinge is of a double-layer structure, and whitening pressure and rice discharge are controlled through a hydrostatic bearing air cylinder outside the hinge. The rice sieve mainly solves the problems of existing of a part of non-whitened parts, a low germ retention rate and rice cavity residue when rice is discharged from a hexagonal rice sieve ofan existing rice mill each time, meanwhile, the whitening pressure can be automatically controlled, germs can be automatically retained, and the rice can be completely discharged after being processed each time.

Description

technical field [0001] The invention relates to a rice sieve for a whole grain rice milling machine and a hexagonal rice sieve, in particular to a rice milling sieve for a commercial whole grain germ rice machine. Background technique [0002] Most of the existing rice mills use horizontal hexagonal rice sieves. The whitening pressure is easy to control, the technology is mature, and the cost is low. For long-grain indica rice, it is easy to break, there are many broken rice, the germ end is easy to be stressed, and the germ is easy to fall off or even disappear. [0003] In addition, the sieve is easily rusted by the phytic acid corrosion of grains, and the germ preservation of whole grains has been paid more and more attention. After many years of practice, the present invention adopts vertical rice milling, the grains fall under gravity, the force on the germ end is lighter, and the germ retention rate is greatly improved. Contents of the invention [0004] The hexagona...
