0.6% is not to be exceeded containing miscellaneous total amount by the paddy after stone remover, wherein 1/kg is not to be exceeded containing sandstone, containing barnyard grass
130/kg is not to be exceeded.
6th, flow scale 8:A paddy flow scale 8 is provided with behind stone remover 4, mainly measures the amount of paddy, for meter
Calculate labour's account cost and provide safeguard and calculate rice milling yield.
7th, hulling machine:Purpose is to make paddy husking, and brown rice, paddy and husk are carried out into husk separation by selection by winnowing.Will
Ask:Paddy husking rate is more than 80%, in rice husk separation process, is no more than 30/kg, the rough mixing of paddy containing full grain grain in rice husk
Amount containing rice husk is no more than 0.8% in thing.
General to use gas hold-down roller hulling machine, the equipment yield is high, and energy consumption is low, and noise is low, and roll-in regulation is accurate, is easy to certainly
Dynamic control, drum structure is simple, the features such as convenient disassembly.Paddy passes through feed arrangement, is entered in the form of individual layer grain material
Rice huller paddy working face, makes working face (two rubber rolls, referred to as fast slow rollers or fixed and moving of the paddy side by two different motion speeds
Roller, for working face made of rubber) extruding, rub the effect of tearing with the hands and slough rice husk (also referred to as extruding rub with the hands avulsion shell).According to rice
The floating velocity of shell has larger difference with paddy, brown rice, therefore available pneumatic concentration separates rice husk from the lower thing of rice huller.In addition,
Rice husk and paddy, the density unit weight of brown rice, coefficient of friction etc. also have larger difference, thing under rice huller is produced well automatic
Classification, is then engaged with pneumatic concentration again, is more beneficial for improving the effect of selection by winnowing separation and reduces energy consumption.Typically using outside suction
It is preferable with wind regime separation rice husk effect, device interior is in negative pressure state, raised so as to avoid outside equipment dust.Directly hulling
Paddy machine discharge port end has drops down plate, air register and aspiration channel for husk separation, makes automatic point of generation when thing is by dropping down plate under rice huller
Level, by air register regulating air volume, is sucked away in aspiration channel, has reached the effect of husk separation.
8th, grain separating machine 6 and plansifter for paddy separation 7:It is required that brown rice rice containing amount is no more than 30/kg, rice huller paddy is returned containing rough
Amount is no more than 10%, returns the machine material flow and is less than 40% with the ratio between rough flow only.
The rough separation of paddy mainly uses gravitational separation process, i.e. gravity type paddy separator, using paddy and brown rice on proportion, surface
The difference of the physical characteristics such as coefficient of friction, by inclined in two-way and coarse work face of reciprocating vibration is done, produces mixture of paddy and husked rice
Raw automatic classification, paddy " floating ", and brown rice " sinking ", brown rice are upward to move from work under the promotion of coarse work face boss
Make the top discharge in face.Paddy then moves down in the presence of self gravitation and charging thrust, is discharged by lower outlet, so as to real
The rough separation of existing paddy.
Plansifter for paddy separation 7 is rubbed using paddy and brown rice in granularity, proportion, unit weight and surface roughness and surface
The difference of the physical characteristics such as coefficient is wiped, mixture of paddy and husked rice is produced automatic classification, dynamics on the compass screen surface for making plane rotation motion
Greatly, proportion is small, shaggy paddy floats on material upper strata, and small, more smooth than great, the surface brown rice of granularity is sunken to bottom
Layer.Brown rice contacts with compass screen surface and passes through sieve aperture, turns into screenings, paddy is obstructed by brown rice layer, and can not be contacted with compass screen surface, no
Sieve aperture easily is passed through, turns into oversize, so as to realize the rough separation of paddy.
In this process, gravity type paddy separator is used for the separation of main body mixture of paddy and husked rice, and plansifter for paddy separation 7 is used for
Gravity type paddy separator isolates back the secondary screening of the mixture of paddy and husked rice of the machine, it is therefore an objective to improves separating effect.Because gravity paddy is rough
Seperator is the separation of main body mixture of paddy and husked rice, in equipment debugging, can be turned net rough mouth and paddy mouth down, it is ensured that net rough matter
Amount, reduce in paddy and contain rough amount, so as to avoid the secondary rice huller paddy of brown rice.
9th, rough device is moistened:Peeling degree is to weigh the Main Basiss of rice processing accuracy.Due to brown rice peel layer and endosperm knot
Close very close, all cortexes of brown rice are all ground relatively difficult, particularly some moistures are very low, storage time compares
Long brown rice, many economic benefit and rice cracked rice, have a strong impact on processing enterprise can be produced by reaching the high machining accuracy of comparison
The reasonable utilization of paddy resource, therefore, brown rice is carried out moistening rough.Brown rice most preferably enter grind moisture when, it is rough go out white rate highest, go out broken
Rate is minimum, and power consumption most saves, and product quality is best.The optimum moisture of general long-grained nonglutinous rice pearling is 15%, therefore the size of rate of water added,
Gap according to optimum moisture and the original moisture of brown rice is foundation.If the moisture of the brown rice after shelling close to optimum moisture,
0.3% or so water need to only be added, it is therefore an objective to moisten cortex, and supplement the moisture loss during pearling.It can use and spray
Water dispenser, ensure the uniformity of dampening.Moisten it is rough carried out in net rough storehouse, it is typically quenched using cold water, moisten the rough 1 hour time.
10th, the first abrasive type rice whitening machine 901:Because brown rice surface is harder, therefore using grinding the pearling mode based on pearling of cutting,
Rough pearling is carried out out to brown rice with sand roller rice machine.During work, by the finished net brown rice of Qian Dao workshop sections, enter from feed hopper and grind
In rice machine whitening chamber, with the rotation of sand roller, brown rice advances along sand roller perficial helical, and the abrasive action that sand roller is rotated by high speed obtains
To pearling, finally by the helicla flute in sand roller, the grain of rice is pushed to exit, is flowed out from discharging gate.Meanwhile in strong air draught
Under effect, force chaff powder to depart from the grain of rice, discharge sieve aperture, finally by suction chaff systematic collection rice bran.
11st, second and third, four, five abrasive type rice whitening machines:Rice needs to grind processing procedure sequence by multiple tracks, pressure in the machine of rice mill
Small, light fine ground mill, endosperm is damaged small, few, then rice milling yield raising of cracking rice, the rough white irregularity of reduction.Due to the structural strength of long-grained nonglutinous rice
It is poor compared with the polished rice in northeast, therefore, during rice whitening, the side of three-level, level Four or Pyatyi sand roller rice machine pearling can be used
Formula, typically using level Four, Pyatyi sand roller pearling.Multistage light stone roller, reduces whitening pressure, so as to reduce out broken rate, improves finished product
Rice milling yield.Threeway is installed after per pass sand roller rice machine, is easy to the flexible operating of technique, i.e., according to the processing situation and product of raw material
Matter requirement, the different technological process of appropriate selection.Concentration equipment is equipped with before per pass rice machine, avoids magnetisable material damage from setting
It is standby.
12nd, white rice grader:Each white rice grader is preferably flat turn sieve, in the 3rd abrasive type rice whitening machine 903 and the 5th sand roller
Behind rice mill 905, white rice grader is placed respectively.First white rice grader 101, it is mainly used in extracting first three road sand roller husk rice
Cracked rice caused by machine, so as to mitigate the operating pressure of follow-up equipment.Carried in this road it is broken during, can suitably relax whole rice
Requirement, only extract small brokens.Second white rice grader 102 is mainly used in extracting all broken caused by former road sand roller rice machines
Rice, be advantageous to be lifted the processing quality of rice, mitigate the pressure store of cool rice barn.Carried in this road it is broken in, to be strict with whole rice
Requirement, can by it is big it is broken be put into follow-up roller and select machine to carry out final election, selected, the whole rice and general meter Yi Qi chosen are imported into
The cool cool rice of rice barn.Small broken and big broken rice can be packed or be sent to as needed with rice device, match somebody with somebody rice for finished product.
13rd, refiner:White rice grader yield is high, has again and the function of chaff is gone with cool rice except dwelling.But either plane
Roto-siofter or slide sieve, all can not be clean by whole rice and separation of cracking rice, and often contains whole rice in cracking rice containing cracking rice in whole rice.Will
Want to obtain crack rice few whole rice and the whole rice crack rice mixed people as far as possible in of containing as far as possible to put forward more, it is simple by the method screened
It is difficult to gather effect.Refiner is a kind of equipment being classified by length, and its separative efficiency is high, strong adaptability, but yield is relatively low.Such as
The outlet material of rotary flat sieve is handled with refiner, then, the quality and quantity of whole rice will be enhanced.Refiner is profit
It is classified with the pocket material different to length.Refiner typically uses cylinder separator, and its main working parts is in one
Surface strikes out the horizontal cylinder of pocket, also known as roller.Short grain collecting tank is provided with roller.It is small it is broken, in it is broken then can be in cylinder
Inner surface forms relative motion contact pocket and separated.Cylinder refiner mainly plays an inspection, so favourable
In the rice milling yield for improving finished product rice.The processing of this procedure be hundred meters of gradation sizings from it is various crack rice, recovery, which is mixed in, cracks rice
In whole rice, while cracking rice for similar size is sorted out, accomplishes that homogeneity merges.
14th, cool rice barn 10:For rice polishing, whether brightness and the broken index of increasing, cold rice polishing are substantially better than hot rice and thrown
Light.Therefore, increase cool rice barn before polishing machine and carry out cool rice technique, make meter Wen close to room temperature, after not only improving rice polishing
Brightness, increasing broken 1~2% can be reduced, improve rice percentage of head rice, increased caused by reducing fuel factor broken.
This technology uses the cool rice of cool rice barn 10 12 hours, and smooth treatment is done in storehouse, it is ensured that material is first without dead angle, material in storehouse
Enter and first go out, to rice barn inside heat absorption dehumidification treatments, surrounding every 1 meter of height in storehouse is set to be seen the middle seamless steel pipe by holes punched on surface
Window is examined, is easy to understand rice barn inner case in time.Cool rice barn uses multiple exit structure, specifically determines to export according to the area in storehouse
Number, typically using 2~6 outlets.
15th, with rice device 11:With the packaging of rice device 11 with rice barn, with rice device and belt conveyor, from rice barn discharging opening
Rice grain pattern out is crossed with rice device with being fallen on after rice on belt conveyor, and the elevator in downstream is then transported to by belt conveyor
In.In recent years, horn of plenty rice product structure, more and more used in newly-built rice factory and match somebody with somebody rice technique.It is general to use in China
General rice is matched somebody with somebody into rice in the way of certain formula collocation, mixing.Key equipment with rice be flow controller (matching somebody with somebody rice device) and
Mixing apparatus.Whether rice device is matched somebody with somebody using positive displacement or weight-type, its purpose is just as, and is all intellectualized operation, automatically
Change degree is high, and operation is also simple and convenient.User presses according to each flow value for matching somebody with somebody rice device of formula setting, intelligent flow regulating system
The system mathematic model is adjusted, and drives valve execution system regulation hopper section, flow is reached setting value, completes to match somebody with somebody
The quantitative criteria of rice.
From the material come out with rice device 11, typically conveyed using belt conveyor.Upper and lower lamination, into following process work
During sequence, will preferably it mix.Mixing apparatus need not be specially equipped with, causes to increase broken.
In addition, the capacity with rice device typically takes the storage time of 1~2 hour to calculate.Storehouse number typically takes 4~6, with rice
Place big broken, whole rice, other kind rice etc. respectively, some clients also require by it is small it is broken be also individually placed in finished bin, according to
Need to match somebody with somebody rice.
16th, polishing machine:The polishing of rice is necessary programs of the refined meter Jia Gong with producing high quality white rice, and polishing is mainly borrowed
Help rubbing action to remove the floating chaff of rice surface, increase the luminosity of the grain of rice, increase the fresh-keeping time.Polishing typically uses iron roll
Polishing machine, the operation principle of iron roll polishing and iron roll pearling are essentially identical, wipe from pearling, by collision, polish pressure, rolling, axle
Completed after to conveying and 5 process collective effects of spray damping.But polishing is not to grind to remove overall chaff layer, but grinds and remove trickle chaff
Raised starch particulate on powder and rough surface., from compared with working method is come, following difference be present with pearling in polishing:1. polishing pressure
Power is low;2. the density for polishing grain of rice fluid is small;3. the grain of rice leaves the speed of iron roll during polishing;4. specific yield Polishing Motion
Area is big.In the art using 4 polishings.Per pass polishing uses threeway below, makes technique flexible, is easy to according to raw material
Quality and processing situation, specifically determine technological process.Multiple tracks polishes, and multistage light stone roller, on the premise of quality is ensured, reduces husk rice
Pressure, reduction are cracked rice, and improve the quality and rice milling yield of finished product rice.
17th, color selector:Apparatus of selecting rice color be according to the difference of rice optical characteristics, will be different in rice using photoelectric technology
Coloured particles automatic sorting comes out, and so as to reach lifting rice quality, goes deimpurity effect.Selected thing enters from the hopper at top
Machine, by the vibration of vibrator assembly, sorted materials glide along passage, accelerate the observation area entered in separation chamber that falls, and
Passed through between sensor and background board.In the presence of light source, according to the power and color change of light, system is set to produce output letter
The work of number drive magnetic valve blows out heterochromatic particle and is blown in the waste chamber of receiving hopper, and good sorted materials drop down onto splicing under continuing
Struggle against finished product intracavitary, so as to reach the purpose sorted.
There is good color sorting effect for shallow water Huang in the requirement of high-end color sorting, scab, the rice that shades, once take out of than can
Up to 1:More than 1, it is secondary to take out of than can reach 15:More than 1 is (bad:It is good);Heterochromatic, scab and other impurities are selected once to take out of than can
Up to 1:More than 1, it is secondary to take out of than up to 15:More than 1 is (bad:It is good);Core is selected once to take out of in vain than up to 1:More than 1, it is secondary to take out of
Than up to 25:More than 1;The complete white grain of choosing, complete yellow grain are once taken out of than up to 1:More than 1, it is secondary to take out of than up to 30:More than 1
It is (bad:It is good).
Modern rice processing enterprises, in grain purchases, it is typically all directly to purchase, directly processes, therefore supplied materials quality
Also it is uneven, yellow rice kernel, heterochromatic rice, go mouldy etc. it is more, it is therefore, big using three-level color sorting, lifting during processing arrangement
The processing quality of rice.In the certified products exit of every grade of color selector, using threeway, to improve the flexibility of technique.
17th, packing device 12:The packing method of rice finished product mainly has gassiness packaging, vacuum packaging, three kinds of gas flush packaging.Bag
Dress specification mainly has 1kg, 2.5kg, 5kg, 10kg, 25kg, 50kg equal-specification.Different bags can be selected according to different requirements
Dress mode and packing specification.
In the rice processing industry in modern times, while the technique of use above advantage, make rice in outward appearance, color and luster, mouthfeel etc.
Aspect has larger improvement, not only improves product quality, reduces percentage of raw brokens, improves rice milling yield.
