Abstract

The utility model relates to an iron roll rice polisher, which is applicable for rice whitening operations. A whitening chamber comprises a screw propeller, a rice sieve, a rice roll, a hollow axle, a pressure valve or the like, wherein the screw propeller and the rice roll are fixedly arranged on the hollow shaft, the pressure valve is positioned at the end. The radial cross section of the rice sieve is a regular dodecagon, and the rice sieve is fixed to the appliance body and houses on the periphery of the rice roll. Two symmetrical ridges on milling roll are equipped in the peripheral region of the rice roll, which is uniformly distributed 2-4 jet-air grooves along a circumferential direction. The utility model of the iron roll rice polisher has the advantages of low ground rice rate, low cracked rice rate, low rice temperature rise and low energy consumption, high milled rice rate and high precision.

Description

Iron roll rice polisher

Technical field:

The utility model relates to a kind of iron roll rice polisher, is used for rice pearling operation.

Background technology:

Iron roll rice polisher carries out work to wipe from the pearling principle, and frictional action must carry out under the friction of big pressure; So rice temperature rise, percent cracked rice height, broken rice rate height, rice milling yield are low, are the problem that rice mill manufacturing enterprise all has a bad headache basically.A lot of enterprises take to reduce the way of machine internal pressure in order to address these problems, and caused like this precision of rice of grinding not enough, contain defectives such as more, the lackluster and storage life of chaff powder is short.

Summary of the invention:

The purpose of this utility model provides a kind of iron roll rice polisher, solves various serial iron roll rice polishers and grinds ubiquitous problems such as the rice temperature rise, broken rice rate height, the rice milling yield that are low, percent cracked rice height.

The purpose of this utility model realizes as follows: this iron roll rice polisher relates to the structure of whitening chamber, and whitening chamber is made up of spiral propeller, rice huller screen, rice roller, hollow shaft, pressure door.Spiral propeller and rice roller are fixedly set on the hollow shaft; Pressure door is in tail end; Rice roller main body is a right cylinder, and periphery has the stone roller muscle of 2 symmetries, along circumferential uniform 2～4 road jet-air slots, and outer shroud dress rice huller screen; Rice huller screen and fuselage are fixed.

Rice huller screen radial section profile is a dodecagon.

This iron roll rice polisher has that broken rice rate is low, percent cracked rice is low, rice milling yield is high, precision is high, Mi Wensheng is low, low power consumption and other advantages.

Description of drawings:

Fig. 1 is the front view of the utility model iron roll rice polisher.

Fig. 2 is that A-A among Fig. 1 is to cutaway view.

The specific embodiment:

With reference to Fig. 1, Fig. 2, in fuselage 1 bottom motor is housed, form whitening chamber 4 by spiral propeller 5, rice huller screen 9, rice roller 10, hollow shaft 11, pressure door 3.On fuselage 1, pass through bearings hollow shaft 11, one end of hollow shaft 11 is equipped with belt wheel 7, connects with motor power by belt, and spiral propeller 5 and rice roller 10 are fixedly set on the hollow shaft 11, feed hopper 6 is arranged at fuselage 1 top, and the following outlet of feed hopper 6 is corresponding above spiral propeller 5.Rice roller 10 main bodys are right cylinder, and pressure door 3 is in tail end.Rice huller screen 9 radial sections are dodecagon, cover on meter roller 10 peripheries.Rice huller screen 9 supports by screen frame (unit) 8, screen frame (unit) 8 is fixing with fuselage 1 by gripper shoe 13, rice roller 10 peripheries have the stone roller muscle 12 of two symmetries, article two, grinding muscle 12 is set on meter roller 10 by six soket head cap screws respectively, rice roller 10 is along circumferential uniform 2～4 road jet-air slots, at fuselage 1 middle part bran-collecting bucket 2 is set, the inlet scoop is set on the bran-collecting bucket 2 links to each other, and communicate with whitening chamber 4 with blower fan.Brown rice or semi-finished product rice enter rice mill feed hopper 6, enter whitening chamber 4 by feed hopper 6, grind desirable rice by the wiping of whitening chamber 4 from the pearling effect.The pearling of its mesogranule is to carry out in rice mill whitening chamber 4, by collision, whitening pressure, roll and axially carry four factor actings in conjunction to finish.Whitening pressure is to be set up in whitening chamber by the speed of the grain of rice and impact force, the grain of rice roll can make when not enough the grain of rice local grind too much, also can make local grind not enough; The grain of rice rolls and can make grain of rice two ends be gone to reduce rice milling yield by stone roller when undue.Reasonably design, combination iron roll shape, iron roll muscle quantity, rice huller screen plate shape, the degree of rolling of controlling the grain of rice is the core technology that guarantees the pearling effect.

Claims (2)

1, iron roll rice polisher, relate to whitening chamber, form by spiral propeller, rice huller screen, rice roller, hollow shaft, pressure door, spiral propeller and rice roller are fixedly set on the hollow shaft, pressure door is in tail end, it is characterized in that: rice roller (10) main body is a right cylinder, and periphery has the stone roller muscle (12) of 2 symmetries, along circumferential uniform 2～4 road jet-air slots, outer shroud dress rice huller screen (9); Rice huller screen (9) is fixing with fuselage (1).

2, the described iron roll rice polisher of claim 1 is characterized in that: rice huller screen (9) radial section profile is a dodecagon.
