The present invention is with screen and go two steps of stone to carry out simultaneously, concrete grammar is to utilize the circulated air combined cleaner, the TQZX series circulated air combined cleaner that the present invention selects for use Beifang Grain Machinery Plant, Cangzhou City to produce, this machine is recycling with wind, the screen of material, classification, go functions such as stone, light assorted separation to be melted into a whole, reduced process procedure, simultaneously good impurity removing effect.Also can inquire about the patent No. about the particulars of this equipment is the disclosed specification of ZL99257524.9.
Can put back to after treatment through the impurity wheat of removing after the aforementioned classification in the dirty wheat storehouse in preceding road and recycle, if produce specifically under the less demanding situation of control microorganism, also can add aforementioned impurity wheat by a certain percentage, improve the utilization rate of raw grain, save cost.
Utilize after the classification of circulated air combined cleaner, the screen wheat again through selected, thresh wheat, can enter following water modifier treatment.
Two, it is modified water
Wheat is passing through earlier water management instrument, three leaf pressure dampeners and is adding and enter pre-wheat wetting storehouse behind an amount of moisture and carry out pre-wheat wetting, the percentage by weight control of aforementioned water accounts wheat is at 2%-5%, wheat carries out dynamic memory in pre-wheat wetting storehouse, be slowly to flow specifically in the pre-wheat wetting of the wheat storehouse, wheat is 2-3 hour in the pre-dynamic storage time of wheat wetting storehouse, and wheat goes out the speed in pre-wheat wetting storehouse and can be controlled by feeding auger or feeder behind the vibration discharger at the bottom of the storehouse.
Wheat is deposited in the 2-3hr process in dynamic tempering storage, and wheat embryo can absorb water fast, makes the no free water in wheat surface, is convenient to deliver from godown.Because after wheat absorbed moisture content, the adhesion between scurf, dust and the wheat became loose, be convenient to scurf, dust separates with wheat.The wheat that delivers from godown process paddle mixer or spiral wheat brush machine fully stir isolates scurf, the dust that contains the microorganism that carries disease germs, and removes light the mixing of carrying disease germs by selection by winnowing then, thereby reaches the degerming purpose.Wheat after the degerming adds according to concrete process conditions and enters the wheat wetting storehouse behind the water and carry out long-time moisture and regulate, in order to reach best powder process effect.
Enter the wheat wetting storehouse behind the water of the medium and small Meccah of traditional handicraft and carry out the moisture adjusting, generally leaving standstill the storage time in the wheat wetting storehouse is 16-36hr, and wheat is easy to knot arch, heating in the storehouse; Simultaneously, the epidermis attachment is that microorganism is mainly originated, and moist and relative suitable temperature has created advantage for the growth of microorganism that carries disease germs.Compare with traditional handicraft, this technology has overcome these problems, can in time remove the microorganism that carries disease germs, and can prevent effectively that again wheat from tying arch in the storehouse.
Wheat after modified through aforementioned water again through past stone, thresh wheat handle after, enter next step and wipe skin, degerming.
Three, wipe skin and degerming
This step is primarily aimed at most microbial adhesion in the characteristics on wheat raw grain surface, under the situation that does not influence wheat bran and endosperm quality, utilize high pressure draught, friction scraping, extruding to hit principle of combining, it is residual to remove wheat exocuticle entrained microorganism, heavy metal, medicament.Aforementioned effect mainly realizes that by wiping the skin bacterial remover following part will come to introduce in detail the operation principle of described wiping skin bacterial remover by reference to the accompanying drawings:
See Fig. 1～Fig. 3, the present invention includes frame 5, pressure fan 1, motor 6 and work chamber 3 are installed respectively on the frame 5, see Fig. 5, main shaft 13 is installed in the work chamber 3, main shaft 13 is tubulose, its right-hand member is connected with work chamber 3 right-hand members by axle bed 7, its left end is connected with motor 6 by belt (not expressing among the figure) transmission, and pressure fan 1 is connected with the inner chamber of main shaft 13 by airduct 2, can make in the work chamber 3 after its running to be in malleation.
