Outlet side at cylinder is equipped with a door around upper level articulated elements (38) rotation, and door is opened under the pressure of the material after the peeling that sends; What join with outlet side is the suction side of blower fan, and blower fan is in order to take away fragment; Configuration one shell skin outlet below screen drum; In shell skin gathering-device, install a feeding spiro rod.

Relative position on the diametric(al) of the outlet side of cylinder disposes one at least, preferably disposes two stirring instruments and scraper tool.

Form the enclosing cover of discharging the chamber one of outlet side configuration.

What join later with the outlet side of drum sieve is one to constitute the E shape flange of discharging the chamber, and the stirring instrument is being discharged indoor rotation.

Fixedly upper millstone and rotation lower millstone are placed in mill shell intracutaneous, and saw shape sheet is housed in the crushing gap of mill, and mill is arranged vertically; Saw shape sheet is disposed in the groove of mill periphery; Saw shape sheet removably is fixed tightly in the groove of periphery with pinching screw radially, and saw shape sheet and alternate pad under any circumstance all are arranged in the groove in upper and lower mill relative.

Mill is made the taper shape of inwardly deepening from the edge of axial limit groove.

Upper millstone hangs on the pipeline section of center, through the center pipeline section material to be ground of packing into; The port of export of feed worm is disposed at the top of pipe upper open end; Above the feed worm charging aperture, be provided with charging hopper; A feed pipe penetrates the inside of pipe; Feed pipe is imported water from the water tank that is disposed at the equipment top through valve, and pipe hangs on the adjustable nut, and nut is screwed in screw thread on the external screw thread of pipe, and is supported on the outside of case lid.

Lower millstone is driven by fitting sleeve, and fitting sleeve turns round at the bottom of housing sealedly, and is fixed in the upper end of vertical drive shaft.

Saw shape sheet has the tooth of rounding; Backlash is rounding also, to form waveform.

Mill has radially convex tendon or pocket on its taper seat.

The inventive method is separating for several times, and it is important for the separation of shell skin.The control of water content also is important except time and temperature controlling.Moisture enters the outside of cereal and produces the heat that helps separating in the lock out operation of decortication.Adding moisture incorporation time (for example 15-30 minute) should select like this, promptly should make moisture can infiltrate kind of a cortex, and this is very important.Must carry out the operation that tempers for first and second times in order to break cereal, before milling, need carry out the short for the third time operation that tempers (duration 5-10 minute).Maximum water content is 16% to be suitable concerning tempering before milling.

The inventive method guarantees cereal and seed cleaning, does not have dust and hair etc. fully, and this helps long term storage.

Take off after the clip, it is important really the shell skin being got rid of.In general air-flow the shell leather material is carried out such extraction and transmission for this purpose, so that just do not have impurity in wheat after purification and the cereal, these impurity and shell skin are pulled away together.

Hereinafter, the equipment that method of operating will and provide for this purpose will be described in detail.

The machine of removing the shell skin from cereal at first is described.

This machine can be used for many cereal and seed, comprises the soft or hard wheat.Hard wheat, barley, rye, Malt barley, millet, African millet, green soy bean, Chinese sorghum etc.

All cereal all must add wet process before removing clip.The operator must adjust machine according to processed specific products when operation.Therefore, can be with same speed and water content for rye and wheat.Need different rotating speed and moisture for other cereal.Particularly resemble the responsive cereal of green soy bean and lens and so on.All spherical cereal more easily shell, and for flat and microscler cereal, the processing that improves condition in advance is very important.Client's needs will be decided accurately in general, and client's indication is necessary for carrying out once suitably processing.

Because cereal all has and resembles the same kind leather structure of wheat, wheat will be taken as the present invention and slough kind of the basic example of this innovative techniques of skin.

All dirts, insect, bacterium, rodentine hair, ovum etc. are all when removing the shell skin and remove.Under the condition that does not change the cereal structure, sterilize in this way for final products.Protein content and amino acid whose distribution even after removing clip, still be kept perfectly harmless in cereal.Frictional force when removing clip only is used to remove outside shell skin, the not nutritive issue of offense of damage to corn trees and vegetable products inside.Handle and remove after the clip once carried out improving, cereal can be worn into flour with common grinding equipment without difficulty, and has the output height and produce more economical attendant advantages.The above-mentioned same shell dermal system that removes has utmost point active influence for the rate of recovery of flour with disengage high concentration albumen (mainly from the cereal aleurone cells).This high concentration albumen is to human nutrition, and particularly infant foods are important.This means that removing clip from cereal promptly uses conventional processing method.Also can improve scratch system, this makes that the abrasive dust operation is more economical, more selective, and applicability is more arranged.In the cleaning system of routine bacterium in the cereal and oil reservoir are separated, this has improved the storage and the durability of the flour of producing.And after at first removing clip, situation is just all the more so.

This novel system compares with traditional grinding method, has avoided appearance that cereal is broken, thereby has reduced loss.In addition, the ash content of this grinding method is low.And, can save and temper for the second time, because in the milling of routine, the kind skin behind the exodermis has stoped the moisture that tempers for the first time to infiltrate cereal.

The shell micromicro of removing is used for papermaking economically or is used as pure fibrous material at chemical industry.Quality of fiber is very high, and processing is economical, thereby produces the byproduct with added economic value.

Before removing cereal shell skin, can under Electronic Control, the mediation by means of sensitivity add the processing that water improves condition.

Moisture accumulates gradually in incrustation, and is penetrated into kind of a cortex place, thereby cereal is broken.This makes and more easily depends on friction effect to remove incrustation and need not any percussion.Accompanying drawing has represented that the hammering sheet is the situation that diagonal is arranged in the rotor top, and the hammering sheet is pressed in cereal on the peripheral part that the metallic plate of boring and notch sieves.The cornerite of these sieves only is 180 °, and remainder is covered by the metallic plate of a pickling, makes crust be easier to separate needed heat from kind of a cortex in order to generation.Necessary moisture helps to form heat and make its even distribution in cereal.This method is unique, and it has illustrated first might be at the incrustation of industrial extensive removal cereal and do not damage the reason of big bud.

The germination that these crusts also can be used for Fructus Hordei Germinatus 100% with and without any impurity, this be its in the laboratory, prospect has been opened up in the application in baking in the industrial and beer brewing.

Now wet-milling system, half wet-milling system and dry grinding system are described

The used grinding equipment of this method is a disk mill formula, but some improvement have been done in the rotation of pan-milling surface and lower millstone.

Two mills all have the mill surface of two stage arrangement in wide groove.The shape of groove is tilted conical, and the wide space that is used for air agitation of 3mm is arranged between the groove.It also is to be with tapering that the second level begins, and is that 3mm is wide with the subsidy mill processes, and it is very clear that this sees from figure.

The advantage of the lower millstone of rotation is: do not break phenomenon and produce when milling cereal, and have only one to make flour separate the classification processing easily.Its ripple avoids breaking generation when mill rotates, and the fiber composition is separated smoothly, and after this fibre composition can be got rid of with sieve method.

The operation of milling is undertaken by the cutter that the special shape tooth is arranged, and this cutter uses the material of common band saw to make.The top blade rounding of saw shape part, they can not damage the interior tissue of cereal when milling operation like this.The preparation work of cereal must carefully be carried out gentlely, in order to avoid in the end increase ash content in the flour of Xing Chenging.Its effect of milling is milled similar with roller.

Upper millstone is fixed and the lower millstone rotation.Upper millstone is adjustable, so that the fineness of institute's milling material or the quality of flour can be changed.Can control to prevent that the sword of mill contacts with each other in mill processes by an adjustable hitch, wearing and tearing are quickened.When adjusting, adopt a kind of bikini hitch.If the user uses a kind of electronics hitch, can use electromagnetic system or other system.

The adjusting of aperture can assign to regulate by the central part of mill from top with hand between the mill.Manual adjustments is to have the pipe of fine thread and handle to carry out by one.

3 of hitch is to be used for avoiding the mill lateral tilt with center adjustment, is even contact so that guarantee all surfaces of rotating grinding board when the work running.This is important for even abrasive dust operation and adjustment product particle size, and the product particle size can be sieved.

Whole meal for wholemeal or other cereal can adopt quick grinding method.Can set all particle sizes by screening.

This grinding equipment can be suitable for dry grinding, wet-milling and half wet-milling.

Dry grinding can be used for grain milling thing, seed, beans, spices etc.This grinding equipment is not pulverizer but real abrasive dust equipment.The air cooling is undertaken by the air stream that oneself produces.Rotating speed in the running can be adjusted according to product requirement.

Half wet-milling is used in particular for bread product, corn product and the product that resembles the corn-dodger sample.Water content can be up to 32%.Til seed also can toast processing, does not perhaps toast after grinding dry again.This grinding equipment has a water tank, so that add water in operating process.

Wet-milling is suitable for wheat products, rye and similar cereal.Cereal also can allow to carry out the germination of short time, compares this with dry processing and can change biological structure fully.

When adopting this grinding equipment to carry out wet-milling, current and wheat or corn are simultaneously from the water supply example input on top is milled.Continuous current can prevent that cereal is adhered on the surface of milling.Water also keep milling cleaning surfaces and produce slurries and help improving and mill.These slurries can be used for making bread or other baked goods also can be used to make cake.

When milling, the moisture content of cereal is increased to 42%, and product is ground to the concentration of thin slurries, and slurries mix with hard red dog and hard wheat flour mutually according to the type of required product when leaving grinding equipment.For batter shape production, product is to mix with the hard red dog that the slurry behind the mill of 40% weight adds 60% weight.Importantly, should fast as far as possible mixing behind the mill.When handling fully hard wheat, the shell skin portion loses the tone in kind of the skin, and when with hard wheat, situation is not so just.Fiber keeps clean, and must not add artificial core fibre.Needs according to market adopt various mixtures.

Mixture has 60% hard flour when making bread.The flour that grinds with tradition when doing living face, red dog equally also are suitable for.

Cereal must be taken off clip in advance so that remove clip in wet milling process, and the grain maximum water holding capacity that must temper is 19% o'clock.Removing the method for clip narrates in other invention.

Do the novel method (using wet method) of living face, bread and baked product and compared further advantage with traditional flour milling method, promptly increase recovery rate (for example 15%), reduce bran content, the nutritive value that lowers 8% product when bran content just can keep.The living face of Hun Heing is extruded then, and its flavor is very beautiful.All plumules and fibrous matter all remain in 40% the pasty state additive; And all protein, Cobastab ₂, Cobastab ₁Deng all remaining in the mixture.

The living face product that processes can store for June in dry air after extrusion molding.Handle if carry out drying, the maximum storage phase can extend to 1 year.Yet dry method is slightly different on taste with wet method, and wet method has more attracting taste slightly.Yet extract has increased in wet method, and this all is an advantage to the producers and consumers.

When with wet-milling equipment, the storability of baked good is compared with the roast with the flour system of conventional method, even can increase about 5 days.Obtain this effect without any need for additives and chemicals.

In when dry grinding, it is 8-9 hour the state processing of improving that cereal carries out dwell period with same grinding equipment, and the needs of product (or according to) mills under 18% water content situation then.Corase grind needs conversion subsequently, and correct grinding can provide flour and cake flour (not needing conversion again) this can be used for making powder system product or pasty product.The thing of taste and whole nutritious value; Fiber content, native protein, Cobastab ₂, niacin, Cobastab ₁As the wet-milling process, all preserved.

Above-mentioned abrasive dust equipment can be applied to various seeds and cereal, and can be used for wet-milling, half wet-milling and dry grinding.

When product will consume in several hours, half wet grinding was well, because its taste is extremely beautiful.

Thoroughly cleaning of grinding equipment under any circumstance is to avoid unpleasant taste or to be polluted in the production afterwards.

Below mode of operation is done an explanation

Must check lubrication circumstances before the beginning flour milling, lower bearing adds butter; Upper bearing adds machine oil.The lower millstone of rotation has a little scalloped surface that is divided into 8 similar grooves, so that can retain water when rotated, and with this water is separated with grain.This is also avoided the variation of conglomeration and any volume, and guarantees even charging.

This equipment is made up of the quenched steel component with sharp keen cutting edge, like this, one wheat of air and the cereal sent here with the same level blower fan transmit with less quantity, so that be fed to easily than the canine tooth place and wear into powder, and be fed to the mill periphery than the serration place, to produce the single-size size product.Fixedly on the mill identical surface is being arranged.Less tooth turbulization makes the product of milling continue motion.

Axle is installed on the bottom by two promotion bearings, and top double grate ball bearing is used to control lateral movement, when axle rotates with high speed, need control completely for avoiding any axial damage.As long as lubricated suitably and carry out continuous monitoring, this structure can continue continuous the running.

Now corrugated blade and mill in the attrition process are done as a narration

Various types of blades in processing method of the present invention, have been used with all thickness and size.The top of tooth is made circular-arc to avoid the seed of subcutaneous of broken shell.By shell scytoblastema breast place gently the galling effect can avoid when producing flour subsequently producing dust.With this method of separating gently, endosperm (being interior tissue) is separated from the shell skin of cereal and is not damaged the structure of seed.Mattress is also being supported rotatablely moving of two cereal products between the pan-milling surface.

As carry out traditional flour production in the roller grinding equipment in, the effect of milling produces with various ripples, and promptly tip to tip is blunt to point, and point is to blunt or dull to dull.

Comparing its advantage with the roller grinding equipment is: this method is carried out very fast, might change the profile of mill waveform in this way, as long as at this moment lay down blade, substitutes them with other type blade, and inserts in the same groove just.All operation can be finished in several hours.If only use a grinding equipment, when needs with regard to changeable blade.Various milling during production line when having an own special disk of milling do not need to change blade.Only need adjust aspect speed and the production.Adorn safety device on the roller grinding equipment, the time and the expense of repairing ripple all are sizable.

This surface of milling also can be used for multistage pulverizing, as long as no more than 4 grades, can equip level and two outer levels in two this moment.Output maximum when with 2 grades, and safeguard simple.

A kind of special tool(s) of cutting profile of tooth, as stock, accompanying drawing shows its thickness with bands for band.Making blade can be with the material of the thick 3mm of reaching, and for in the blade insertion groove, blade is made segment shape rather than shape continuously.When grinding equipment was used for comminution of minerals or fibrous material, tooth needed different sharpnesses.Client's needs always can be met, thereby the special material that can obtain to require.

For good effect and the low ash content of grinding, two angles of ripple or wrinkle are very important.25 ° of more shallow angles produce bigger pressure to product.Work to quick separation in 55 ° of angles of broad, especially for sensitive product.When mill is used to pulverize under wet condition, only use the combination of " tip to tip ", its result is for not influence of ash content.Under the situation of some mineral products and fiber product, wrinkle or ripple need have the tip and can not rounding.

Also can use the nonmetal surface of milling.Used in this case milling material depends on the specialities that will grind.The speed of milling also can change.

When the correct row of decision ripple blade counts, adopt follow procedure:

Spacing between the ripple blade always has and wide 3.5mm(3/8 English inch inwards from the outside of groove) the identical thickness of pad that is, and have same profile of tooth to arrange.One gradient is arranged at the bottom of main groove, and its gradient is a 0.0762mm(3/1000 English inch).4 waveform blades that the first order has same profile of tooth to arrange.To finish grinding every 25.4mm 16 teeth.The second level adopts straight kerve in order to adorn 4 circle pads, three circle ripple blade and three pads.The every 25.4mm of blade has ten teeth.In order to guarantee that the main groove of blade safety need not surpass the indication size.Last three every 25.4mm of ripple blade have 6 teeth.Formerly every 25.4mm has the pad between the blade of 10 teeth and the last blade that every 25.4mm has 6 teeth that very important function is arranged: when mill rotates, they help to produce air turbulence, and air turbulence is helpful again conversely to carry away the product that is ground in ground grains the time.

Present device can be made into various sizes.For example, be used for breadboard device and can adopt 150 kilograms of persons of hourly output.Only need smaller drive motors, for example 2 horsepowers for this reason.This device is easy to transportation, is specially adapted to undeveloped country.

Figure 14 has illustrated some embodiment of saw shape sheet, and these saw shape sheets can be used in respectively on upper millstone 113 and the lower millstone 114.Find out obviously that from Figure 14 crown is a rounding, also be defined as circular arc portion at the bottom of the tooth.Obviously find out from Figure 14, saw shape sheet 112a, 112b, 112c, on the tooth depth be different on the number of teeth of unit length.Every 25.4mm is defined as 6 teeth in saw shape sheet 112a, every 25.4mm10 tooth in saw shape sheet 112b, every 25.4mm16 tooth in saw shape sheet 112c.The flank of steeply inclined becomes 55 ° of angles with horizontal line, low-angle flank becomes 25 ° of angles.

Present device is applicable to wheat, other cereal, also is applicable to wet-milling, half wet-milling and the dry grinding of spices, soft mineral and chemical substance.The flour that novel grinding equipment is applied in the food industry is produced, and also is applied to pulverize numerous products, seed (except ginger) for example, chemical substance and light mineral.Mill and realized by two mills 111,114, arcuation saw shape sheet clamps mutually with inserting a shim method in mill.Mill has convex tendon or the pocket that radially extends in apparent surface 134 and 137.

Can obtain a continuous air-flow by means of above-mentioned special structure, it produces a mattress and mildly pulverizes with assurance, and guarantees to mill at low temperatures.This is a particular importance when the flour milling powder, because at this moment must avoid damaging glutamine.In fact, three kinds of different saw shape sheet 112a, 112b and 112c can use.Saw shape sheet reduces driving power simultaneously in order to increase recovery rate, to reduce ash content when the mill wheat.Unclamp screw 136 and just can change saw shape sheet at an easy rate, the ripple on saw shape sheet and the tradition mill has same service life.Yet renewal cost reduces widely, because wearing and tearing only are created on the saw shape sheet.

Power can be internal combustion engine, motor or other power source.
