The technological process of wet method rice bran expansion of the present invention is made up of following steps: rice bran; Cleaning; Air classifier separates; Moisture content and temperature are regulated in foreheater; Steam wet method extrusion; Dry; Cooling; Leach.
In the invention process process, owing in rice bran, generally all be mixed with certain cracking rice and starch, should carry out the strictness screening, crack rice and other impurity to remove.Otherwise, not only influence the foundation of pressure in the puffing process, and can make expanded material loosely organized.Therefore, rice bran will pass through cleaning process earlier, carries out meter crushed rices through sorter then and separates, and enters foreheater and regulates moisture content and temperature.The water content of rice bran is one of essential condition that influences the rice bran expansion effect, and moisture content is too high not to have plasticity, crosses that low then elasticity is too poor, and after regulating through foreheater, moisture is generally 10～13%.The raw material rice bran is gone into the machine temperature also has certain influence to expansion effect, and after foreheater was regulated, temperature was generally 60-80 ℃.Rice bran after handling through the front operation is imported bulking machine by feeder, is mixed in cylindrical shell, the effect of shearing, compression and boiling.Because this process is a process between a high temperature, short time, the general time of staying in cylindrical shell was less than one minute, therefore the activity in the passivation rice bran effectively, do not destroy simultaneously the effective ingredient in the rice bran, this process can also be destroyed trypsase inhibin etc. to be had and cuts material and kill microorganism and worm's ovum in the rice bran, improves gelatinization degree.The expanded rice bran that comes out is because the temperature height, and vaporization moisture is loss fully as yet, and quality is soft, therefore needs dry cold cut, can form the expanded material with certain compression strength.Otherwise, not only significantly increase the fines content of material, leaching is exerted an influence, and also can go mouldy when storing, acid value still can rise.
In Fig. 1,2,3 and 4, steam wet method rice bran expansion machine of the present invention mainly is made up of fast die sinking plate 1, admission opening 2, expanded cylindrical shell 3, concentration equipment 4, feeder 5, stop valve 6, steam input pipe road 7, shear pin 8, expanded tube screw feeder 9, big belt pulley 10.The fixing template 11 of different size on fast die sinking plate 1 is evenly distributed with 24 shoulder holes on template 11, be lined with nib lining 12 in each shoulder hole.
Handle back moisture 10～13% through the front operation, temperature is 60～80 ℃, rice bran through quantitative feeder 5 bufferings, enter expanded cylindrical shell 3 after sending into concentration equipment 4 deironing by the feeding screw feeder, a plurality of admission openings 2 are arranged on bulking machine cylindrical shell 3, by stop valve 6 control, can from one or many places spray into steam.Like this, after a series of effects such as wet, the heat effect of mechanism such as rice bran is squeezed in the oil plant extruder, rubs with the hands, shears, pressurization and the steam that sprays into and frictional heat, at terminal fast die sinking plate 1 place of extruding screw, rice bran sharply expands, moisture evaporates rapidly and obtains loose porous and squeezing and puffing rice bran material that intensity is high.
The present invention compared with prior art has the following advantages: 1, output is big, the output master of expanded pretreating process Knack is due to expanded production capacity, and at present dry method bulking machine processing rice bran ability is 8～20t/24hr, and wets Method bulking machine single machine yield can reach 120t/24hr. The rice bran preliminary treatment workshop that output is 100t/24hr, If join dry method bulking machine then about 5～13 of minimum needs, if join wet-process puffing machine then only anti-1. Through producing actual detection, the wet method puffing material basic proportion of giving money as a gift is 488Kg/m3, and in the butt ratio of method puffing material Heavily be 380Kg/m3, infuser is under same bed depth in the operation of extraction oil producing like this, and wet method is expanded Output will improve more than 25%. 2, power consumption is little, and the supporting power of method bulking machine is on 45～55KW left side The right side, and the supporting power of wet-process puffing machine is 90KW, take the rice bran preliminary treatment workshop of above-mentioned 100t/24hr as Example, the minimum supporting power of dry method bulking machine is 275KW, its power consumption is minimum to be that wet method is swollen More than 3 times of change machine, as to join its power consumption of the lower dry method bulking machine of output will be bigger. 3, parts use Life-span is long, because the heat of dry method bulking machine mainly pushes friction mutually by rice bran and the parts such as machine barrel, spiral And produce, thereby bigger to the wearing and tearing of the parts such as machine barrel, spiral, then need change spiral in general about 30 days, Annual maintenance cost will be very high like this. The service life of the main working parts such as the spiral of wet-process puffing machine can Reach and produce 20000 tons of rice brans, annual maintenance cost is very low. 4, the puffing material leaching effect is good, with dried Method is expanded to be compared, the expanded puffing material that produces of wet method structural better, loose porous, grease fully outside Leak, and be difficult for forming powder, this material not only can not stop up the infuser screen, and the infiltration of solvent, Diafiltration is good, and dregs of rice Residual oil is generally below 1.1%. Steam to take off at solvent and also be difficult in the process producing dust and stop up Condenser. 5, good refreshing effect, the following moisture of rice bran drying to 9% after wet method is expanded, and be cooled to Behind the normal temperature, its acid value increases slower, can store more than 60 days at normal temperatures. Like this, rice bran processing factory can Peak period in paddy processing is purchased rice bran in a large number, stores after elder generation is expanded again, has avoided the peak of paddy processing Phase dare not purchase in a large number, or becomes sour because can not in time processing after the purchase, causes the loss of raw material, the peak period Later the situation of not having again rice bran processing.
