Description
Technical field
The present invention relates to material buffer, cooling and sorting technologies, and in particular to for cool rice, chaff crushed rices point in rice processing
Rice cooling from, arrangement of cracking rice mentions chaff device.
Background technique
The grain of rice can convert thermal energy for some mechanical because rubbing, colliding in pearling, polishing process, make in grain of rice temperature
It rises, due to grain of rice poor thermal conductivity, heat is internally transmitted relatively slowly by grain of rice surface layer, and the grain of rice is made to form biggish temperature gradient and produce
Raw internal stress, will lead to broken rice more than the intensity of the grain of rice or cracks (quick-fried waist).If thinked little of during pearling
It cools, grain of rice temperature is excessively high to will cause grain of rice strength reduction, and pearling increases broken more.Such as rice temperature is excessively high in finished product keeping, no
It is easy to maintain, it is perishable.Grain of rice temperature is excessively high, hurried cooling before being such as packaged, and because grain of rice heat-transfer effect is poor, the inside and outside formation of the grain of rice is larger
Temperature gradient can also generate internal stress, lead to broken rice or crack.
Rice temperature increases, and influences grain of rice intensity, then can generate when pearling, polishing and more crack rice.In addition, in rice milling process
Middle generation cracks rice, rice crushed rices and the part chaff powder that is not sufficiently separated adherency, is mingled in grain of rice surface and the grain of rice, such as too late time-division
Separate out, when subsequent pearling again, polishing, can make it is unsegregated crack rice, chaff crushed rices etc. is pulverized, influence the appearance and by-product of the grain of rice
The comprehensive utilization of product.
At present, it is common to use cool rice barn, the cool rice equipment such as fluidized bed takes cool rice and needs to occupy larger because equipment is larger
Floor level, mounting arrangements are inconvenient, can set cool rice equipment together after can not achieve per pass pearling, polishing, the grain of rice is caused to connect
Continuous pearling temperature increases, and causes to concentrate cooling extent big when cool rice, it is big to generate thermal stress.In addition it is broken also not have separation for such equipment
The effect of rice, chaff crushed rices.
Summary of the invention
It is an object of the invention to: a kind of cooling of rice is provided and mentions chaff device, it is cooling that rice is set up after each road husk rice, polishing
Chaff device is mentioned, grain of rice temperature rise can have not only been reduced, reduce thermal stress, restores grain of rice intensity, reducing broken rice or crack, but also can inhale
Except part rice bran, separate section are cracked rice and rice crushed rices, pearling effect is promoted, may also function as the effect of baffle-box, reduces vertical height
The impact forces that fall and cracking rice for generating.
The technical solution of the invention is as follows: the rice is cooling mention chaff device include material feeding box, cooler bin, grain of rice discharge bucket,

Air door, the rear openings of cooler bin install suspended hood, and the top rear of cooler bin installs material feeding box, the lower front peace of cooler bin
Grain of rice discharge bucket is filled, the bottom rear of cooler bin installs chaff crushed rices discharge bucket, is located at material feeding box in the cabinet of cooler bin and chaff crushed rices goes out
Plate and cooling classification compass screen surface are dropped down under the tilted installation refining of vertical area between hopper；Top edge and the charging of plate are dropped down under refining
The bottom of case is concordant and connect with the discharge port leading edge of material feeding box, and is in Z-shaped reversed dip with plate is dropped down on refining；Cooling classification
Compass screen surface is mounted in the cabinet of cooler bin, removable replacement, and compass screen surface installation site is adjusted, and screen angle is adjusted, cooling to divide
The top edge of grade compass screen surface is concordant with the rear openings of cooler bin, and can move up and down in rear openings plane and adjust its installation position
It sets, the lower edge of cooling classification compass screen surface and the bottom face contact of cooler bin and energy circle are between grain of rice discharge bucket and chaff crushed rices discharge bucket
Bottom plane in be moved forward and backward and adjust its installation site, and with plate is dropped down under refining in Z-shaped reversed dip；It is dropped down under plate under refining
Gap between edge and cooling classification compass screen surface forms suction chaff and separates suction inlet.
Further, material feeding box is in cuboid, and length × width × height is 2D × 4D × 2D；The feed inlet of material feeding box it is upper
Side connects the elephant trunk of supplied materials, is equipped with feed gate at feed inlet；The intake port of material feeding box is D, the pipe range 60mm of feed inlet
Left and right；Plate is dropped down in material feeding box on refining to be rectangle, inclination angle is 48o or so；The discharge port of material feeding box be length × width be 0.2D ×
The rectangle of 4D.
Further, cooler bin is in cuboid, and length × width × height is 7D × 4D × 5D；It is rectangular that plate is dropped down under refining
Shape, length × width are 4D × 1.4D or so, and tilt adjustable section, inclination angle is 45o or so；Cooling classification compass screen surface is rectangle,
