Abstract
A rice fine processing and cold polishing technique includes a vertical paddy entering silo-a primary screen-a permanent magnet drum-a vibration cleaning screen-a stone removing machine-a main scouring machine-a secondary scouring machine-a fine mesh screen-a gravity paddy slug separator-a first paddy pounder-a second paddy pounder-a third paddy pounder-a rice grading screen-an abrasive finishing machine-a color selector-a rice grading screen-a length grading machine-a vertical silo for finished product-an electric flow scale-a package. The present invention is characterized in that a vertical rice cooling silo used for cooling the temperature of the rice is arranged before the abrasive finishing machine. The present invention changes the defect of the traditional thermal polishing technique. The present invention adopts the mode of combining natural cooling and mechanical cooling, thus greatly improving the cooling effect, increasing the rice yield by 4 percent, greatly reducing the rate of cracked rice and subliming the rice quality not only from the appearance, but also from the inner quality.
Description
Technical field
The present invention relates to the fine-processing technique in a kind of rice process, more particularly it is a kind of cold polishing technique of rice finish machining.
Background technology
At present, rice is in the fine finishining process, the phase mutual friction makes the temperature of rice more and more higher between (particularly abrasive type rice whitening machine etc.) and the paddy because processing equipment, the temperature of rice is too high in process, damaged the internal physical performance of the grain of rice, make the soft of grain of rice change, frangible, therefore have in the existing process in polishing machine and carry cooling process by machinery spray wind or at polishing machine front conveyer belt of increase, but these several mechanical cooling method effects are all undesirable, rice when in rice mill, coming out general Mi Wenjun about 45 ℃, adopt the glossing of this form to be called the heat polishing.This polish temperature can influence meter matter and and use a meter rate coefficient (per hundred jin of paddy go out a rice jin number) and reduce.So the temperature that reduces rice in the fine finishining process becomes the important topic in the current rice fine finishining process.
Summary of the invention
The objective of the invention is to overcome above-mentioned existing disadvantages of background technology part, and a kind of cold polishing technique of rice finish machining is provided.The mode that it adopts nature cooling and machinery cooling to combine has improved cooling-down effect greatly.
Technology of the present invention by the inventor many times experiment screening obtain.
The objective of the invention is to reach: cold polishing technique of rice finish machining by following measure, it comprises that paddy advances grain vertical silo → receiving sieve → pipe magnetic separator → vibratory cleaning sieve → stone remover → main hulling machine → secondary hulling machine → refiner → gravity type paddy separator → first road rice mill → second road rice mill → the 3rd road rice mill → white rice grader → polishing machine → color selector → white rice grader → length grading machine → finished product vertical silo → electronic flow and claims → pack, and it is characterized in that being useful on before polishing machine the cool rice vertical silo of cooling rice temperature.
In technique scheme, the structure of described cool rice vertical silo comprises and rest on the ground iron net formula cylindrical shell 1 and be positioned at underground inclined rice tube 2, described iron net formula cylindrical shell 1 and inclined rice tube 2 are integral structure, on the inclined plane of inclined rice tube 2 blast pipe 3 is arranged, blast pipe 3 is many discharge pipes 31 in iron net formula cylindrical shell 1 top set, and a discharge pipe 31 is fixed on the iron net formula cylindrical shell 1 by steel pipe.Exhaust fan 4 is equipped with on iron net formula cylindrical shell 1 top, and rice-entering port 5 is arranged at the top of iron net formula cylindrical shell 1, and rice output outlet 6 is arranged at the bottom of inclined rice tube 2, and rice is delivered in the polishing machine by elevator by rice output outlet 6.
In technique scheme, described blast pipe 3 and discharge pipe 31 are mesh-like structure, and the diameter of bore of described blast pipe 3 and discharge pipe 31 is greater than outer bore dia.
The present invention has following advantage: 1., the cooling method by force ventilation cooling and underground rice tube combines, and increases cooling-down effect greatly, generally the rice temperature can be reduced to below 27 ℃, in addition lower.2., iron net formula drum surface, blast pipe and discharge pipe be mesh-like structure, and diameter of bore is greater than outer bore dia, iron net formula cylindrical shell can conveniently dispel the heat.Blast pipe and discharge pipe can make things convenient for air-out cooling, and the rice grain of rice can not enter blast pipe and discharge pipe inside, are air intake mode down, can improve cooling-down effect, hot gas is discharged by top exhaust fan 4, lands from top to bottom at rice, can guarantee that cold wind fully contacts with rice.3., the inclined-plane of inclined rice tube can increase the surface cooling area, helps the downslide of rice simultaneously.4., the cool rice vertical silo among the present invention can be determined the cool rice time as required, and guarantee that the grain of rice reaches cool meter temperature.And existing conveyer belt carries the time of the cool rice of cooling shorter.5., to have improved rice milling yield about 4%, broken rice rate reduces greatly, no matter make meter matter still is that inherent quality is elevated from sense organ.6., Fully-mechanized operation, reduce labor workload.7. production technology is simple, and is effective.
Description of drawings
Fig. 1 is a cold polishing technique of rice finish machining flow chart of the present invention.
Fig. 2 is the structural representation of cool rice vertical silo among the present invention.
The specific embodiment
Describe performance of the present invention in detail below in conjunction with accompanying drawing, but they do not constitute limitation of the invention, only give an example.Simultaneously by illustrating that advantage of the present invention will become clear more and understanding easily.
Consult accompanying drawing as can be known:cold polishing technique of rice finish machining of the present invention; It comprises that paddy advances grain vertical silo → receiving sieve (effect of removal of impurities) → pipe magnetic separator (effect of de-iron) → vibrating cleaning sieve (effect of removing sand) → stone remover (removing the effect of stone) → hulling machine (effect of rice huller paddy) → refiner (effect of selected grain) → gravity type paddy separator (except the rough shell of empty paddy) → first rice mill → second rice mill → the 3rd road rice mill → white rice grader (with the rice graduation) → polishing machine (increasing the whiteness of rice) → color selector (removing variegated) → white rice grader → length grading machine → finished product vertical silo → electronic flow and claims → pack, and it is characterized in that being useful on before polishing machine the cool rice vertical silo of cooling rice temperature.
The structure of cool rice vertical silo is: it comprises and rest on the ground iron net formula cylindrical shell 1 and be positioned at underground inclined rice tube 2, described iron net formula cylindrical shell 1 and inclined rice tube 2 are integral structure, on the inclined plane of inclined rice tube 2 blast pipe 3 is arranged, blast pipe 3 is that many discharge pipes (are generally five in iron net formula cylindrical shell 1 top set, as shown in drawings, it is few also can to increase as required or slow down) 31, a discharge pipe 31 is fixed on the iron net formula cylindrical shell 1 by steel pipe.Exhaust fan 4 is equipped with on iron net formula cylindrical shell 1 top, rice-entering port 5 is arranged at the top of iron net formula cylindrical shell 1, and (rice enters rice-entering port from classifying screen, naturally landing from top to bottom), rice output outlet 6 is arranged at the bottom of inclined rice tube 2, and rice is delivered in the polishing machine by elevator by rice output outlet 6.Blast pipe 3 and discharge pipe 31 are mesh-like structure, and the diameter of bore of described blast pipe 3 and discharge pipe 31 is greater than outer bore dia.
