Description
technical field:
The present invention relates to a kind of paddy processing equipment-rice mill.The effect of this rice mill is divested by the brown rice superficial cortical layers formed after paddy husking, becomes edible rice.
background technology:
Rice mill uses existing more than 100 years history in the world, the breakthrough that its core component whitening chamber is structurally never technically large, is still made up of roller, rice cutter sieve.Roller plays a part to grind cuts brown rice epidermis, and the effect of rice cutter increases pearling room pressure, increases pearling effect.The subject matter that traditional pearling mode exists be energy consumption large, crack rice many, its reason is that traditional handicraft brown rice is cut in process with roller helical rotation at stone roller, 10-8mm gap is left between knife of rice mill and roller, the grain of rice has to pass through this gap, circulate, husk rice room entirety is communicated with, and this structure makes stone roller cut required Relative friction effect greatly to weaken, also for no reason consume a large amount of power, ton rice power consumption is generally at more than 20kw.Distance simultaneously due to grain of rice walking is long, and whitening chamber pressure is comparatively large, and the energy of brown rice for cutting, peeling off in pearling process has quite a few to be converted into heat, and make grain of rice temperature rise comparatively large, consumes energy brings adverse consequences again.Because rice temperature rise is not easily stored, follow-up also need increases cool rice equipment, and broken rice rate is also higher, cracks rice total amount generally about 15%.
Summary of the invention:
The invention provides a kind of belt lattice stream rice mill and husk rice method, secured the movement locus of rice stream by screening body, prevent the grain of rice with roller in whole rice machine helical rotation, remarkable economize energy, improve rice milling yield and husk rice effect.
Belt lattice stream rice mill, its composition comprises: feed arrangement, whitening chamber, drawing mechanism, transmission device, frame, described whitening chamber comprises between 2 groups of husk rices of being with and sieving body to surround by milling, and the roller at described frame two ends walked around by described band of milling, and forms endless belt, described screening body and described milling have gap between being with, described gap is less than 2 millimeters, is negative pressure space between the external side of described screening and shell, and described negative pressure space connects induced-draught fan.
Described belt lattice stream rice mill, described screening body is along band arrangement of milling, total arrangement is Long Circle, described screening body has sieve aperture, described sieve aperture width is 0.6-1.8 millimeter, the length of described sieve aperture is 8-20 millimeter, described sieve aperture oblique arrangement, and described screening body bottom has side discharging opening.
Described belt lattice stream rice mill, described flat board band or the chain of band for having installed sheet of milling of milling, described sheet of milling is bar shaped, is fixed on described flat board band or chain, and described sheet of milling is that sand sheet or metal are milled sheet.
Described belt lattice stream rice mill, described screening body has gap adjusting mechanism, is 4-100 between described husk rice.
Described belt lattice stream rice mill, the cross section between described husk rice progressively reduces from top to bottom.
Described belt lattice stream rice mill, described frame comprises framework, upper connector, lower connector, and described screening body upper end connects upper connector, and lower end connects lower connector.
Described belt lattice stream rice mill, described transmission device comprises active roll tube and passive roller, and described band of milling is wrapped on active roll tube and passive roller, and active roll tube drive under rotary work.
Described belt lattice stream rice mill, described adjacently mills between sheet and/or monolithic is milled between sheet and had air intake duct, and described sheet of milling has the pusher groove to lopsidedness, and described pusher groove is wide at the top and narrow at the bottom.
Described belt lattice stream rice mill, described screening body space governor motion is spiral governor motion, and conveyor screw one end is connected with screening body, and the other end is connected with the upper and lower connector of frame.
A kind of method utilizing above-mentioned belt lattice stream rice mill to carry out husk rice, brown rice enters between husk rice through feed arrangement, through roller and brown rice relative motion, carry out surfacing processing, brown rice circulates according to spatial mode shape and falls in husk rice, the chaff powder produced immediately enters negative pressure space through screening body and is siphoned away by wind, and the brown rice that chaff pruinescence wind siphons away rear surface does not have chaff powder to lubricate continues grinding at the volley, finally falls into outside drawing mechanism eliminating machine.Described spatial mode shape is the type shape that roller and screening body surround, and grain of rice movement locus falls gradually in circulation process.
Beneficial effect:
1. the rice stream in traditional vertical rice whitening machine is through the gap rice cutter and roller at whitening chamber movement locus, along with roller does vertical screw, the rice stream of traditional horizontal type rice mill is along with roller does horizontal screw at whitening chamber movement locus.
The rice stream of rice mill of the present invention is motion in the husk rice of whitening chamber, and movement locus moves downward for spinning in only between certain husk rice.The present invention, owing to changing the type of flow of rice stream on the whole, decreases unnecessary power consumption, and under identical output, power consumption of the present invention reduces by 50% than conventional types, and broken rice rate reduces 30% simultaneously.Energy consumption reduces greatly, general below the 10kw of ton rice power consumption, and the total amount that simultaneously makes to crack rice reduces to less than 10%, and rice mill of the present invention, by the technical parameter of adjustment whitening chamber internal pressure and sheet of milling, also can be made into polishing rice machine.
2. in use mill sheet and screening body of rice mill all can have and to a certain degree wear and tear, by the gap that clearance adjustment mechanism adjustable is sieved body and milled between sheet, prevent the grain of rice from passing, ensure that the grain of rice only carries out circulation circulation in some specific husk rices.
3. traditional rice mill limits due to structure, and separate unit output, below 10 tons/hour, generally needs the series connection of 3-5 road rice machine just can reach pearling effect, and per pass rice acc power is generally at about 45KW, and separate unit rice machine cannot accomplish larger output because of power and structure restriction.
Rice mill two roller pitch of the present invention, from lengthening, increases roller section length, increases considerably single machine yield.The output of separate unit rice machine can reach 20 tons per hour, the present invention because of single-machine capacity little, husk rice is effective, can just reach pearling effect by a rice mill, reduces husk rice cost, improves production efficiency.
