Description

A kind of wind cylinder type rice whitening machine

Technical field

The present invention relates to the grain processing equipment technical field, particularly a kind of wind cylinder type rice whitening machine.

Background technology

Existing rice whitening machine, its principle mostly are that the brown rice after peeling off is placed in the rice milling chamber, by rice milling roller it are rolled, and the wiping stripping between the recycling grain of rice is wiped the epidermis of brown rice, thereby reached the purpose of pearling.Because wiping the stripping process is in rice milling chamber, its radiating condition is relatively poor, and the process of rolling is with certain pressure in addition, thereby the temperature of its grain of rice percentage of damage higher, rice is also higher, and simultaneously, its output is lower, and energy consumption is also larger.

Summary of the invention

For the deficiency that prior art exists, technical problem to be solved by this invention provides the rice whitening equipment that a kind of output is large, power consumption is few, low, the cool rice of broken rice rate is effective, the peeling rate is high.

For solving the problems of the technologies described above, the technical solution used in the present invention is a kind of wind cylinder type rice whitening machine of invention: be by air duct 13, husk rice lining 7, advance mitron 8, discharge nozzle 6, hopper 3, aggregate pipe 2 and unload meter device 1 to consist of; Advance mitron 8 and be the tangential direction device on the top of air duct 13, husk rice lining 7 devices are at the inwall of air duct 13, and discharge nozzle 6 is inserted into the middle and upper part of air duct 13 inner chambers from top to bottom; Hopper 3 devices install successively aggregate pipe 2 and unload meter device 1 in the lower end of air duct 13 under it; Be provided with pointed raised tooth more than two at the inner surface of described husk rice lining 7, form sand shape rough surface 9.

On the inner surface of described husk rice lining 7, also be provided with spiral helicine delay bulge loop 10.

Described husk rice lining 7 is to be made of the husk rice liner plate more than two.

Wind cylinder type rice whitening machine of the present invention, in employing is installed in air duct with the method for sand shape rough surface husk rice lining, use the operation principle of cyclone dust collector (that is: the Asta-3746 that is commonly called as), allow high pressure draught that brown rice after peeling off produces by high pressure positive blower enter along the tangential direction of air duct from advancing mitron, so that brown rice is close to constantly rotation on the sand shape rough inner-surface of husk rice lining along with high pressure draught, and then, wipe gradually the rice skin on brown rice surface.Because in the process of peeling, do not roll process, thereby its broken rice rate is lower, the peeling rate is also higher; Simultaneously, owing to be in carrying under one's arms of high pressure draught all the time, so its temperature is lower, cool Mi Xiaoguo is better, can save follow-up cool rice operation, is conducive to follow-up quality of finish; In addition, the pearling process of brown rice is to be carried under one's arms by high pressure draught, and speed is higher, thereby its output is higher, and power consumption is less.According to prototyping testing, wind cylinder type rice whitening machine of the present invention is compared with the conventional equipment of same size, and its broken rice rate can reduce by 10%, and power consumption can reduce by 20%, and equipment cost can reduce by 15%.

The specific embodiment

Below in conjunction with drawings and Examples, the present invention is further illustrated; Following explanation is to adopt the mode that exemplifies, but protection scope of the present invention should not be limited to this.

Present embodiment comprises air duct 13, husk rice lining 7, advances mitron 8, discharge nozzle 6, hopper 3, aggregate pipe 2, unload meter device 1, hopper flange 4, lower flange 5, upper flange 14 and air duct lid 15.

The upper end of air duct 13, is advanced mitron 8 and is the tangential direction device at an upper portion thereof with lower flange 5 with upper flange 14, lower end; Husk rice lining 7(is made of the husk rice liner plate more than two usually, also can adopt whole tubular) device is at the inwall of air duct 13, on its inner surface, be provided with the pointed raised tooth more than two, form sand shape rough surface 9, simultaneously, on the inner surface of husk rice lining 7, also be provided with spiral helicine delay bulge loop 10; After discharge nozzle 6 passes the hole of air duct lid 15 centres from top to bottom, be inserted into the middle and upper part of air duct 13 inner chambers; The upper flange 14 of air duct 13 is fixed with air duct lid 15 usefulness bolts.

Hopper 3 devices are in the lower end of air duct 13, and its upper end is fixed with the lower flange 5 usefulness bolts of air duct 13 with hopper flange 4; The bottom of hopper 3 is installed successively aggregate pipe 2 and is unloaded meter device 1.

Before the use, the rice outlet tube that the ajutage of high pressure positive blower 11 is connected with the brown rice dispenser connects, and with advance mitron 8 and be communicated with.Simultaneously, the port of export of deduster 17 with discharge nozzle 6 is communicated with, and rice bran discharger 16 and air outlet 18 are communicated with deduster 17.

During use, open first high pressure positive blower 11, the high pressure draught that allows high pressure positive blower 11 produce enters the inner chamber of air duct 13 from advancing mitron 8; Then, open brown rice dispenser 12 and deduster 17.At this moment, the brown rice that is provided by brown rice dispenser 12, carried under one's arms by the high pressure draught that high pressure positive blower 11 produces, enter in the husk rice lining 7 of air duct 13 inner chambers at a high speed, owing to be that tangential direction from air duct 13 inner chambers pours, thereby brown rice can be close to along with high pressure draught inwall (that is: the sand shape rough surface 9) rotation of the husk rice lining 7 of air duct 13 inner chambers; In rotary course, the pointed raised tooth on the sand shape rough surface 9 can be wiped stripping to the epidermis of brown rice; After several times rotation, the epidermis of brown rice namely can be taken off by wiping, becomes the pearling rice.Spiral helicine delay bulge loop 10 on husk rice lining 7 inwalls can prolong the holdup time of brown rice on husk rice lining 7 inwall sand shape rough surfaces 9, improves and wipes the stripping effect.When high pressure draught is being carried under one's arms the rice of brown rice and pearling under the effect of gravity and air stream outlet direction, when dropping to hopper 3, by the rice of pearling under Action of Gravity Field, fall in the hopper 3, and enter into the aggregate pipe 2 of its underpart, and last, draw off by unloading meter device 1.High pressure draught then turns to, and guides top into by the air inlet of discharge nozzle 6 lower ends, guides deduster 17 into by its port of export again, and through dust removal process, air-flow is discharged by air outlet 18, and the rice bran of collection is then drawn off by rice bran discharger 16.

Wind cylinder type rice whitening machine of the present invention both applicable to general rice processing, also applicable to high quality white rice processing, also can be used for high-grade polished rice processing.
