Abstract
The utility model relates to a rice-cooling upright cylindrical silo for cold finishing of rice, which comprises a wire netting type cylinder (1) on the ground and an inclined rice cylinder (2) under the ground, wherein an air inlet pipe (3) is arranged on the inclined plane of the inclined rice cylinder (2) which is divided into a plurality of air outlet pipes (31) on the wire netting type cylinder (1), a ventilating fan (4) is arranged on the upper part of the wire netting type cylinder (1), a rice inlet (5) is formed on the top of the wire netting type cylinder (1), and a rice outlet (6) is formed on the bottom of the wire netting type cylinder (1). The rice-cooling upright cylindrical silo overcomes the disadvantages that the prior hot polishing process can influence the rice quality and reduce the milled rice rate coefficient. The rice-cooling upright cylindrical silo greatly increases the cooling effect and the milled rice rate, and improves the rice quality at the same time in the manner of combining a cooling mode by mechanical ventilation and a cooling mode by the underground rice cylinder.
Description
Technical field
The utility model relates to a kind of cool rice device in a kind of rice process, and more particularly it is a kind of cool rice of rice cold polishing technique vertical silo that is used for.
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 having in the existing process is generally increasing a conveyer belt conveying cooling by machinery spray wind or the operation before polishing machine in polishing machine, these several mechanical cooling method effects are all undesirable, rice Wen Jun adopts the glossing of this form to be called " heat polishing " about 45 ℃ when generally coming out in rice mill.This polish temperature can influence meter matter and and use a meter rate coefficient (per hundred kilograms of paddy go out meterkilogram 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 purpose of this utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of cool rice of rice cold polishing technique vertical silo that is used for is provided, and the mode that it adopts nature cooling and machinery cooling to combine has improved cooling-down effect greatly.
The purpose of this utility model reaches by following measure: be used for the cool rice of rice cold polishing technique vertical silo, it is characterized in that it comprises rest on the ground iron net formula cylindrical shell 1 and is 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.
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 utlity model has following advantage: 1., the cooling method by force ventilation cooling and underground rice tube combines, and improves 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.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, only give an example.Simultaneously by illustrating that advantage of the present utility model will become clear more and understanding easily.
Consult accompanying drawing as can be known: be used for the cool rice of rice cold polishing technique vertical silo, it is characterized in that it comprises rest on the ground iron net formula cylindrical shell 1 and is 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, 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.
Through facts have proved: the cold polishing of rice is compared with the heat polishing and can be reduced about broken rice rate 3-5%, for an enterprise that produces 40000 tons (by 70% measuring and calculating) per year, rice finished product and 1000 yuan/ton of thin rice price differences, have more 2080 tons of rice finished products, be equivalent to 7750 mu one season paddy rice output, 2,080,000 yuan of new returns.10 yuan/ton of labour costs are saved in rice processing, and 3.11 yuan/ton of the newly-increased processing electricity charge save production cost 360,000 yuan.By increasing cold polishing technology operation, company can increase 2,440,000 yuan of economic benefits newly.
