Abstract

The utility model relates to a quick testing rice mill which is a rice mill mainly used for rubbing, rubbing off and whitening. A whitening rice roller of the utility model adopts a structure combining a milling rib with an auxiliary milling rib; an included angle is formed between a milling rib edge and the axial direction of the whitening rice roller; a rice sieve adopts a circular arc sieve smaller than 180 DEG; the circle center of a circular arc of the rice sieve is eccentric with the circle center of the whitening rice roller; sieve meshes and the direction of the rice sieve are unbalanced to the axial direction of the whitening rice roller. The structure enables the rice mill to improve rice hull breaking rate of rice and whitening effects largely, and the cuticular color of the finished rice can be improved largely, with improved particle size.

Description

Test rice mill pearling rice roller and rice huller screen device fast

The utility model relates to a kind of rice mill device.

Fast testing rice machine is that motor and devices for husking rice bluntly combine as a whole based on a kind of meter machine of friction wiping from pearling, is applicable to and identifies the use of high quality paddy grade.The test rice machine of Shi Yonging in the market, white gluten cutting edge on the pearling rice roller and pearling rice arbor are to there not being angle, grind in the rice finished product that and also contain a small amount of husk, the pearling uniformity is bad: rice huller screen is the semi arch sieve less than 180 ° simultaneously, rice huller screen is concentric with pearling rice roller during installation, the space that makes working space form is bigger, and husking yield, rice finished product granularity all are difficult to reach standard-required; Rice huller screen sieve aperture length direction and pearling rice arbor are to consistent, and directly influence rice machine is got rid of the ability of cavings, and has increased power consumption.

The purpose of this utility model is for shell-breaking rate that improves paddy and pearling effect, makes cavings along the smooth and easy eliminating of sieve aperture direction, thereby makes the rice finished product precision reach standard-required.

The utility model is achieved in that

This device is by motor 1, locknut 2, rice huller screen 3, rice huller screen bar 4, pearling rice roller 5, whitening chamber 6, cover plate 7, weight 8, relay 9, grind muscle 10, grind muscle cutting edge 11, the auxiliary muscle 12 that grinds, rice huller screen sieve aperture 13, rice huller screen sieve wall 14 is formed, pearling rice roller 5 and motor 1 directly connect, be distributed with on pearling rice roller 5 excircles and grind muscle 10, grind the muscle of stone roller cutting edge 11 is arranged on the muscle 10, rice huller screen sieve aperture 13 is arranged on the rice huller screen 3, rice huller screen sieve aperture 13 is a rectangle, grind muscle cutting edge 11 and axially become angle with pearling rice roller 5, between stone roller muscle 10, auxiliary white gluten 12 is arranged, auxiliary white gluten 12 is the muscle of the dark projection of band muscle on the pearling rice roller 5, rice huller screen 3 is the circular arc sieve less than 180 °, the center of circle decentraction of the rice huller screen 3 circular arc centers of circle and pearling rice roller 5, rice huller screen bar 4 centers and pearling rice roller 5 are centered close on the same center line.

The direction of rice huller screen sieve aperture 13 and pearling rice roller 5 are axially not parallel.

Compare with existing test rice machine, the utlity model has following advantage:

Pearling rice roller 5 is because the stone roller muscle cutting edge 11 that distributes on the excircle axially becomes angle with pearling rice roller 5, and auxiliary white gluten 12 is arranged on the excircle, makes meter machine at work to the squeezing action reinforcement of paddy, thereby the shell-breaking rate of paddy and pearling effect are improved greatly.

Because rice huller screen 3 is the circular arc sieve less than 180 °, the installation site of rice huller screen bar 4 and pearling rice roller 5 centers are on same center line, make reduce corresponding of maximum interspace of the whitening chamber 6 between circular arc sieve and the pearling rice roller 5 with minimum aperture, paddy is packed into behind the whitening chamber 6, high speed rotation along with pearling rice roller 5, paddy is subjected to the auxiliary white gluten 12 of rotation at a high speed and cuts with the stone roller that has the stone roller muscle cutting edge 11 of angle in suddenly big or suddenly small whitening chamber 6, the weight 8 of rice machine constantly presses down simultaneously, whitening chamber 6 spaces reduce gradually, the rice huller screen sieve wall 14 and the grain of rice, produce extruding mutually between the grain of rice and the grain of rice, friction, reach rice and go out white effect in blink, husking yield improves, and the peeling of rice finished product surface evenly, color and luster is bright and clean, has improved granularity.

Rice huller screen sieve aperture 13 directions and pearling rice roller 5 are axially not parallel, form angle, have increased the grinding time of grain on same sieve aperture, can make cavings along the smooth and easy row's chaff of sieve aperture direction again.

Fig. 1 is the fast testing rice machine structure chart.

Fig. 2 is pearling rice roller 5 structure charts.

Fig. 3 is the structure chart of rice huller screen.

Fig. 4 is pearling rice roller 5 and rice huller screen 3 work structuring figure.

Be illustrated below in conjunction with accompanying drawing.

Test rice machine pearling rice roller 5 and motor 1 directly connect, stone roller muscle cutting edge 11 on the stone roller muscle 10 that distributes on pearling rice roller 5 excircles axially becomes angle with pearling rice roller 5, the dark auxiliary white gluten 12 of band muscle is arranged on the pearling rice roller 5 that grinds between the muscle 10, such structure is ground when cutting paddy, can improve the shell-breaking rate and the pearling effect of paddy.Cut evenly for making to grind, on pearling rice roller 5 excircles, evenly distribute 4 and grind muscle 10 and grind muscle cutting edge 11, the auxiliary white gluten 12 of 2 symmetries is wherein arranged between 2 of symmetry.

Rice huller screen 3 is the circular arc sieve less than 180 °, the installation site of rice huller screen bar 4 and pearling rice roller 5 centers are on same center line, make reduce corresponding of maximal clearance of the whitening chamber 6 between rice huller screen 3 and the pearling rice roller 5 with minimum clearance, paddy is packed into after the whitening chamber 6, high speed rotation along with pearling rice roller 5, paddy has added the auxiliary white gluten 12 that is subjected to rotation at a high speed in the little whitening chamber 6 greatly and the stone roller that grinds the stone roller muscle cutting edge 11 on the muscle 10 cut suddenly neglecting, and be subjected to constantly pressing down of weight 8, the space of whitening chamber reduces gradually, the sieve wall 14 and the grain of rice, produce mutual extrusion between the grain of rice and the grain of rice, friction, in the of short duration time, just can reach rice and go out white effect, and husking yield is improved greatly, and the peeling of rice finished product surface evenly, and color and luster is bright and clean, has improved granularity.

Rice huller screen sieve aperture 13 is a rectangle, and its direction and pearling rice roller 5 axis form angle, have so just increased the grinding time of grain on same sieve aperture, and have made the smooth and easy eliminating of cavings.
