Abstract

The utility model discloses a continuous rice whitening machine, which belongs to a machine in the mechanical field of foodstuff. The utility model can make coarse rice whiten fine rice. The whitening machine can be combined for using with a blowing vacuum thresher. The utility model is a novel rice thresher. The coarse rice whose shell is threshed is in the whitening machine. The coarse rice is rotated and rubber between rice cutters and a rice sieve under the action of two rotary rice cutters. Then chaff is removed and the coarse rice is changed into fine rice. The whitening machine of the utility model has the advantages of simple operation, safety, reliability, convenient maintenance and strong applicability. When the utility model is used, the utility model has no dust pollution, low noise and low energy consumption. The rice discharging rate of the utility model can be improved by 5-15%. Besides, the utility model can not damage rice germ.

Description

Continuous rice whitening machine

The utility model application is dividing an application of original application, and the applying date of original application is 921112, and application number is 92221623.1, and invention and created name is novel rice mill.

The utility model rice machine is to belong to the machine that in the grain machinery field brown rice pearling is become polished rice.This rice machine and wind drum-type vacuum hulling machine are united use, are a kind of novel rice mills.

Traditional rice mill that China uses at present is that employing two rubber roller tube mutual extrusion reach the purpose with the brown rice pearling, because brown rice pushes in two rolls, the grain of rice is broken easily, cause the rice serviceability rate low, particle is many, and the machine floor space is big, and power consumption is high, noise is big, operation is dangerous, inconvenient maintenance is sharp.

The purpose of the present utility model is in order to overcome the shortcoming of traditional rice mill, to improve rice milling yield, reduce and crack rice, cutting down the consumption of energy.

The content of the utility model rice machine invention is that the brown rice of sloughing husk is sent in the rice machine, between rice cutter and rice huller screen, rotate friction by two on the effect utilization rice cutter of twice rotation rice cutter protruding keys drive brown rice and remove rice bran, the brown rice pearling is become polished rice.

(1) is the brown rice bucket; (2) be control valve; (3) be a meter cutter; (4) be rice huller screen; (5) be a meter cutter conveyor screw; (6) be the protruding key of meter cutter; (7) be a meter cutter air-out slotted eye; (8) be power transmission shaft; (9) be the bearing block perforate; (10) be driving member; (11) be the polished rice separator; (12) be row's chaff mouth; (13) be to contain the rice device; (14) be the spring control gate; (15) be attachment pegs.

Concrete enforcement of the present utility model: continous way rice machine is placed on the below of wind drum-type vacuum hulling machine brown rice outlet.The brown rice that is come out by the vacuum hulling machine enters brown rice bucket (1), control valve (2) is equipped with in brown rice bucket (1) below, to regulate the rice amount, the brown rice of process control valve (2) enters the first road rice sector to carry out just grinding, rice sector mainly is made up of rotation rice cutter (3) and hexagonal rice huller screen (4), rice cutter (3) preceding half section are cylindrical screw body (5), second half section is that outer rim has two protruding hollow cylinders of being good for (6) and having air-out slotted eye (7), rice cutter (3) is driven by the hollow power transmission shaft of part (8) and rotates with 1400/ component velocity, hexagonal rice huller screen (4) divides the two halves inclusion in rice cutter (3) outside, and case also is stamped in rice huller screen (4) outside.

In first stone roller process, the rice cutter (3) of rotation, to be introduced into the brown rice that a meter cutter (3) conveyor screw (5) locates and deliver to a meter cutter (3) second half section, utilize rice (3) two protruding keys of cutter (6) to drive brown rice spin friction between rice cutter (3) and rice huller screen (4) and remove rice bran, utilize air blast to be transported to the interior air blast of Hollow Transmission Shafts (8), blow away rice bran through rice cutter air-out slotted eye (7) outflow, discharge rice bran from taking off the chaff gas flow tube.

The rice that ground through the first road rice cutter enters the second road rice cutter, the first road rice milling process repeatedly further with the rice pearling, enters in the polished rice separator (11) through the polished rice of secondary pearling, the residue rice bran is discharged from row's chaff mouth (12), and polished rice is sent into and contained in the rice device (13).

At the rice output outlet place of twice rice cutter spring control gate (14) is installed all, to control out Mi Sudu, spring control gate aperture is little, and it is slow to go out Mi Sudu, makes brown rice rotate the fraction time lengthening in the rice cutter and increases the whiteness of polished rice, otherwise then reduce the whiteness of polished rice.

The air blast that air blast is sent is to deliver in the Hollow Transmission Shafts (8) and polished rice separator (11) of first, second road rice cutter (3) by plastic film capicitor respectively.Have the hole (9) of ψ=30mm on the bearing block of rice cutter (3) power transmission shaft, be connected with the air intake plastic film capicitor.

The utility model rice whitening machine and wind vacuum huller are united use and are had the following advantages:

1, vacuum shelling, continuously pearling, rice are not broken, rice milling yield can improve 5～15%, and not damage the plumule of rice.

2, easy and simple to handle, safe, reliable, easy to maintenance, applicability is strong, and hulling machine has overcome the single shortcoming of old-fashioned machine purposes applicable to cereal such as paddy and wheat, grain, Chinese sorghum, buckwheats.

3, the few floor space of machine accessory little, economize ground 4/5 than old-fashioned machine, and can arbitrarily move and can be placed on land, also can be placed in the ship and use.

No dust pollution when 4, using, noise is little, energy consumption is low, improved work situation.
