Description
Technical field
The invention belongs to foodstuff processing technology apparatus field, and in particular to grain medium husk rice technical equipment, particularly one
Plant sand ball flexibility rice mill and a kind of grain medium husk rice method.
Background technology
As existing grain husk rice technology, mainly there are cutting Mill technique, extruding Mill technique and cutting extruding joint
Mill technique.In grain (including paddy, wheat, corn, coarse cereals etc.) husk rice enterprise, conventional rice milling unit, by husk rice work
Skill is classified, and mainly has abrasive type rice whitening machine, iron roll rice polisher, sand roller iron roll combined rice mill；Arranged by roller and classified, mainly had sleeping
Formula rice mill and vertical rice whitening machine；By the quantity point of roller in rice mill, mainly there are single roller rice mill, double roll rice polisher and multiple roll
Rice mill.The distribution of muscle and mill groove is ground by roller surface, continuous muscle and segmentation muscle, straight muscle and spiral bar, succeeding vat is broadly divided into
With a fault trough etc..At present, will there are three aspects in grain husk rice owner both domestic and external.First is roller straight with grain grain
Connect contact area smaller.The roller of rice mill either sand roller or iron roll, grain grain is with roller directly contact area less than grain grain
Between contact area 2%.Second is larger pressure in husk rice room.Because grain grain is limited with the directly contact area of roller,
Method that can only be by increasing the pressure in husk rice room, increases the frictional force between grain grain, improves husk rice effect.But husk rice chamber pressure
Power increases, and will make broken rice rate increase, rice milling yield reduction.In addition, as husk rice room pressure increases, the energy consumption of rice mill will increase
Plus.3rd is that roller rotating speed is very fast.In order to increase in the roller unit interval with grain grain directly contact area, generally using improve grind
The method of roller rotating speed is realized.Either abrasive type rice whitening machine or iron roll rice polisher, the rotating speed of roller generally 800r/min~
Between 1500r/min.The rotating speed for reducing roller can be greatly reduced broken rice rate and energy consumption, but husk rice effect can also declined, no
The process goal of husk rice can be completed.In order to increase rice milling yield, reducing broken rice rate and reduce husk rice energy consumption, many engineers and technicians
Many research and development are done with scientific worker to work.

3 parts are the chaffs after vibration separation sieve separation, then are inhaled into chaff separator.After chaff is separated through chaff separator, packing and storing.
Husk rice room diameter d2With hollow shaft diameter d1Ratio between 5~20；Diameter in hollow shaft between blade top
d3With husk rice room diameter d2Difference between 60~200mm；Husk rice room height h and husk rice room diameter d2Ratio 1.5~
Between 6.5；
Grain medium husk rice method is technically characterized in that：Referring to accompanying drawing 5, accompanying drawing 6, by grain and sand ball quality dispensing,
Compound conveying, the husk rice of sand ball flexibility, compound lifting, the flexibility husk rice again of sand ball, grain and the classification of sand ball mixture, finished product
Workshop section's compositions such as arrangement, the recovery of sand ball and recycling.
1. ingredient station
The mass ratio of grain (including brown rice, wheat, corn, coarse cereals etc.) and sand ball is between 1~10；Sand ball it is straight
Footpath is between 5~25mm；Using continuous batching mode, by the sand ball dispensing in the grain in grain storehouse and sand ball storage warehouse.
2. sand ball flexibility husk rice workshop section
Grain enters the charging aperture of sand ball flexibility rice mill with the mixture of sand ball through conveying equipment, as shown in Figure 2.Grain
The compound of food and sand ball completes flexible husk rice under the mechanical force collective effect of gravity and sand ball flexibility rice mill blade
Journey.The compound for completing flexible rice milling process through sand ball flexibility rice mill is discharged from sand ball flexibility rice mill discharged orifice, under
Road workshop section.The chaff produced in sand ball flexibility rice milling process is suctioned out from sand ball flexibility rice mill row's chaff mouth, through arranging chaff pipe, into chaff
Separator.In addition, the chaff also row's of the remittance chaff pipe suctioned out from rice mill discharged orifice, into chaff separator.
3. grain is classified workshop section with sand ball compound
After grain is through 2~10 flexible husk rices, grain enters vibration separation screen with the compound of sand ball, using vibration point
The vibration of level sieve and the collective effect of the size in sieve plate hole and suction chaff wind net, finished product (grain), sand are turned into by compound classification
Ball and chaff.Wherein finished product through finished product collator classification, it is selected after packing and storing.Sand ball warp conveying equipment, makes sand ball return to sand
Ball storage warehouse, then be circulated and use.Chaff is focused on chaff separator by chaff through inhaling chaff wind net, is collected, packs, is stored.
The present invention is had an advantageous effect in that：
1. the area of directly milling of grain is increased.By being mixed into sand ball in proportion in grain, than the sand of existing rice mill
The area increase of directly milling of roller or iron roll is nearly 100 times, is conducive to milling for grain grain top layer chaff skin to come off.In addition, only in diamond dust
The directly contact area of cylinder surface and grain grain is greater than the area of milling of original rice-milling roller or iron roll.
2. using the flexibility husk rice of sand ball than cutting husk rice or small using the pressure that iron roll extrudes husk rice using sand roller.Due to grinding
The indoor pressure of rice reduces, and the mechanical force and internal stress that grain grain is born will also reduce, thus advantageously reduce broken rice rate, also have
Beneficial to increase head rice yield and rice milling yield.
3. husk rice is cut or compared with iron roll extrudes husk rice using sand ball flexibility husk rice and sand roller, the rotating speed of roller can be significantly
Reduce, in addition to the pressure of husk rice room is reduced, the power of rice mill can also be reduced, and be conducive to energy-saving.
