Description

Equipment is used in maize flour production

Technical Field

The invention relates to the field of agricultural machinery, in particular to equipment for producing corn flour.

Background

The corn contains a large amount of lecithin, linoleic acid, grain alcohol, vitamin E, cellulose and the like, has various health care effects of reducing blood pressure, reducing blood fat, resisting arteriosclerosis, preventing intestinal cancer, maintaining beauty and keeping young, delaying senility and the like, and is also a suitable good product for diabetics. The corn flour completely retains the nutritional ingredients and conditioning functions of corn, and overcomes the defects of poor taste and difficult digestion of coarse grain flour food. Food prepared by taking corn as a raw material is endlessly seen, and corn baking, corn cake and the like are common, wherein corn noodles are popular in the market.

The prior art corn flour manufacturing method is as follows: after the corn is picked, peeling the corn to obtain corn cobs; placing the corn cobs in an open field for airing, so that the moisture in the corn cobs is 13-15%; threshing the corn cobs to obtain corn kernels; and crushing the corn kernels to obtain a finished product.

The invention patent with application number 201510454144.9 discloses a sweet corn threshing device, which utilizes a three-roller clamping mechanism to clamp corn cobs to rotate downwards, and when the corn cobs contact with a cutter head, the cutter head cuts the roots of the corn cobs so as to achieve the purpose of threshing. The device has the following defects: workers need to stand on a production site all the time and keep the corn cobs in a vertically downward state before processing, so that the labor intensity of the workers is extremely high; when the worker leaves, the device idles, which is not beneficial to energy saving; after threshing is finished, the corn kernels are also mixed with dust and dander, impurity removal is needed in the later period, and the processing period is long; the device can only thresh one corn cob once, and the treatment efficiency needs to be improved.

The invention patent with application number 201711283141.9 discloses a combined threshing device for processing corn, which can rapidly thresh and dry, and adopts a feeding mode that gravity presses a baffle plate to rotate, so that the corn can enter from a gap between the baffle plate and a hopper. Although the device can realize automatic feeding, the feeding speed is not effectively controlled. The corn cobs in the hopper continuously enter the threshing tank in the previous corn cob threshing process, so that the corn cobs are influenced mutually, and the threshing efficiency is prolonged to some extent. In addition, corn is always left in the hopper of the device, and the problem of insufficient feeding is caused. Furthermore, the device adopts the relative rotation between the transversely arranged threshing cylinder and the corn cobs to realize the threshing process, the threshing efficiency is lower in the mode, the corn kernels are easy to damage in the threshing process, and the threshing effect is not ideal.

The invention patent with application number 201711010750.7 discloses a corn crushing mechanical device with impurity removal function, which firstly utilizes a lifting device to lift corn kernels to a certain height before crushing treatment, and utilizes the gravity of the corn kernels to enable the corn kernels to move up and down on a spring in an impurity removal box so as to achieve the purpose of impurity removal. Although this mode can realize the edulcoration of kernel of corn and handle, the in-process energy consumption is great, is unfavorable for the cost saving, and can not detach the impurity of adhering to on the kernel of corn surface, and the edulcoration effect also remains to be improved. In order to ensure the quality of finished products, the corn kernels are required to be subjected to primary dust removal treatment before crushing treatment, and the opening state of a dust removal device is required to be kept in the dust removal process, so that the cost is further increased. In addition, the device has higher requirements on the dryness of the corn kernels, corn flour is easy to agglomerate under the condition of higher humidity of the corn kernels, the corn flour is easy to deteriorate, the quality guarantee period is shorter, and the storage is not facilitated.

At present, the two procedures of threshing and crushing are mostly independent from each other, that is, after the corn is threshed by a threshing device to obtain corn kernels, the corn kernels need to be conveyed into a crusher by adopting a manual or mechanical conveying mode (such as a conveying belt, a screw elevator and the like) to be crushed. Due to the fact that large invalid time exists between the two working procedures, the working continuity is poor, and the working period is long.

As is well known, the industrial production process of noodles sequentially comprises a dough kneading device, a dough pressing device, a noodle cutter, a cutting cutter and the like from front to back according to the process flow. In a noodle processing device disclosed in patent application 201510377409.X, the stirred material flows into a pre-rolling groove through a discharge port of a dough kneading device through the dough kneading device, and two cakes are produced by extrusion of a pre-rolling roller; the two flour cakes are compounded into one flour cake through a compound roller; then obtaining a thin pancake by the extrusion of a roller; and then the dough sheet is cut into long noodles with specified width under the action of a dough knife. The long surface after the division is cut by a cutter blade to cut the long surface into a predetermined length.

Since noodles contain a large amount of flour which is agglomerated when it is exposed to water, the prior art dough kneading apparatus such as that disclosed in patent application 201621440445.2 provides a good kneading effect for pure dough or a small amount of auxiliary materials mixed therein, but when it is necessary to add other dispersible auxiliary materials to the flour, since the aforementioned flour itself is agglomerated in water easily, other granular auxiliary materials are not easily taken into the dough, resulting in a poor uniformity of mixing.

One solution to solve the above problems is to separate the raw materials by dry-wet separation, first mix the solid raw materials in advance, and then mix the mixed solid raw materials with liquid raw materials (water, milk, eggs, etc.), thereby improving the dispersion uniformity of the raw materials. Therefore, a stirring device is required to be arranged in front of the dough kneading device, and after the uniformly stirred granular materials are put into the dough kneading device, the granular materials are stirred with the liquid raw materials.

Patent application 201720199323.7's patent discloses a high-efficient mixing sieving device of flour, the function of stirring mixture and screening has, mix and close the stirring with the screening as an organic whole, practice thrift the space, structural design is reasonable, install the arc stirring leaf that the longitudinal symmetry set up on the (mixing) shaft, stirring range is wide, stirring mixing efficiency is high, and because first spring setting, the arc stirring leaf is at the stirring in-process, the vibration is great, make flour be difficult for gluing on the arc stirring leaf, mix the certain time after when the flour stirring in the agitator tank, open manual ball valve again, and start the bobbing machine through the electric cabinet, make mixed abundant flour fall on the screen cloth, sieve, mix more evenly abundant like this, can also play fine filter effect simultaneously. However, in food processing, the production amount is large, the efficient flour mixing and sieving device adopts the arc-shaped stirring blades arranged in the stirring box for stirring, if the stirring box is too small, the production efficiency is low, and if the stirring box is too large, the powder materials are difficult to be uniformly mixed only by the stirring action of the arc-shaped stirring blades.

Patent application 201520766551.9 discloses a flour raw material mixing machine, which comprises two feeding mechanisms respectively located at two sides of the top of a mixing bin, wherein different materials such as flour and vegetable powder can be respectively loaded into the mixing mechanism, and then the flour and the vegetable powder are mixed by the mixing mechanism, three groups of stirring blades in the mixing mechanism are respectively distributed on the upper part, the middle part and the lower part of a stirring rod, so that flour can be fully mixed, the mixed flour falls onto a screen mesh from a discharge port of the mixing bin and then enters a vibrating screen through the screen mesh, and due to the vibration of the vibrating screen, the flour mixture falling onto the screen mesh is easily fed into the vibrating screen after being screened by the screen mesh, and is uniformly mixed for the second time under the action of the vibrating screen, and becomes looser, so that the flour can be conveniently kneaded at the later stage; however, the feeding mechanism adopts a spiral propelling device, and in the feeding process, due to the extrusion among materials, the powder bodies are more compact, and after the powder bodies enter the mixing bin, the raw materials are difficult to mix and are easy to agglomerate, so that the mixing effect is influenced; although it is through setting up multiunit stirring vane, improves the stirring and mixes the effect, nevertheless when mixing the storehouse too big, also the effect is limited, and can't solve the problem of powder caking, influences subsequent production and processing.

According to the corn cob turnover device, the corn cobs are fed into the steering mechanism, the steering mechanism conveys the corn cobs, and the corn cobs are turned over in the conveying process, so that the axes of the corn cobs are consistent with the conveying direction. After the corn cobs are subjected to the inertia force and enter the channel dividing mechanism through the rear end of the steering mechanism, the channel dividing mechanism divides the corn cobs into an upper channel and a lower channel, and continuously feeds materials to the processing unit from the two channels. The corn cobs enter the two mutually separated threshing channels through the two feeding holes 1131 of the feeding unit respectively, and the threshing rollers 121 rub the corn cobs back and forth in the process that the corn cobs fall gradually, so that the corn kernels and the corn cobs are effectively separated. Because the grain diameter difference between the corn kernels and the corn cobs is large, the corn kernels can enter the space between the upper screening net 132 and the lower screening net 131, and the corn cobs are isolated on the upper screening net 132 and are discharged by the corn cob discharging port after passing through the upper screening net 132. During threshing, the lower screen 131 continuously reciprocates up and down to disperse the corn kernels on the lower screen 131. Impurities such as dust, dander, etc., which are contaminated in the corn kernels, are deposited at the bottom of the main housing 113 through the meshes of the lower sieving net 131. The discharge of the corn kernels can be realized by opening the valve at the corn kernel discharge port at regular time.

After the corn kernels enter the crushing box 11 through the hopper 12 communicated with the feeding hole of the crushing box 11, the corn kernels gradually fall down by gravity. During the falling process of the corn kernels, the air supply mechanism 59 blows air towards the corn kernels through the air nozzles 28, the light impurities, dust and the like doped in the corn kernels are light in weight, the light impurities and the dust can be blown to the upper guide plate 29, and the corn kernels can continuously fall and are isolated on the crushing material screen 25. After the corn kernels are supported by the crushing screen 25, gravel, crushed stones, etc. mixed in the corn kernels fall through the meshes of the crushing screen 25 and are continuously deposited on the gate 13 of the crushing box 11. During this process, fresh water may be introduced into the particle tank 11 through the fresh water tank 36, the fresh water being introduced in an amount to completely submerge the corn kernels. And starting the lifting cylinder 21, wherein the lifting cylinder 21 drives the upper saw teeth 26 to move in the vertical direction relative to the crushing screen 25 until the upper saw teeth 26 move above the liquid level. The material crushing motor 22 is started, the material crushing motor 22 drives the rotating shaft 24 to rotate, and the rotating shaft 24 drives the lower saw teeth 27 to rotate. The lower saw teeth 27 rotate to stir the clean water in the crushing box 11, the corn kernels move along with the clean water, and impurities attached to the surfaces of the corn kernels are separated from the corn kernels and are continuously deposited on the material door 13 of the crushing box 11 through the crushing screen 25.

After the corn kernels are soaked in clear water for a preset time, the feeding door 13 is driven to turn downwards through the feeding power mechanism, the discharge hole of the crushing box 11 is opened, and crushed stones and water fall through the discharge hole and fall into the water storage chamber 30. After the discharge port of the crushed aggregate box 11 is opened for a preset time, the discharge door 13 is driven to reset through the blanking power mechanism, and the discharge port of the crushed aggregate box 11 is completely closed. Above-mentioned process can in time discharge away impurity such as rubble by crushed aggregates case 11, prevents that impurity such as rubble from sneaking into the maize meal after smashing again, has guaranteed the quality of maize meal.

After impurity such as rubble discharges away through the discharge gate, still can spray the clear water towards bin gate 13 through clear water tank 36 and outlet pipe, after discharging impurity such as rubble by the discharge gate, the discharge gate is in encapsulated situation, drives through lift cylinder 21 and goes up sawtooth 26 and be close to crushing screen cloth, and lower sawtooth 27 is close to bin gate 13 to drive through crushed aggregates motor 22 and go up sawtooth 26 and lower sawtooth 27 and rotate. During the rotation of the upper saw teeth 26, the upper saw teeth 26 crush the corn kernels, and after the corn kernels are crushed to a certain size, the corn kernels fall through the crushing screen 25 and are secondarily crushed by the lower saw teeth 27. The kernel of corn is changed into powdered by original graininess in crushed aggregates case 11, carries out predetermined time after the broken handling process, drives through unloading power unit drive and drives bin gate 13 upset downwards, and crushed aggregates case 11's discharge gate is opened, and maize flour is along bin gate 13 downstream gradually, is collected in the guide intracavity that reservoir chamber 30 and lower stock guide 31 formed after breaking away from bin gate 13. The electromagnetic valve at the water outlet 32 is closed, the electromagnetic valve at the material outlet 33 is opened, the corn flour falls on the conveyor belt 40 through the material outlet 33 of the material guide cavity and passes through the drying unit in the process of moving along the conveyor belt 40, the corn flour is dried by the drying unit, and the moisture on the corn flour is effectively evaporated. The process can effectively reduce the humidity of the corn flour and prolong the storage time of the corn flour while realizing the quick feeding of the corn flour. In addition, before the corn flour is fed, the electromagnetic valve at the water outlet 32 is opened, the electromagnetic valve at the feed outlet 33 is closed, the gravel and broken stones falling from the discharge port of the crushing box 11 fall into the material guide cavity, and the gravel and broken stones fall to the bottom of the water storage chamber 30 through the water outlet 32 of the material guide cavity. This mode design benefit can realize the function of arranging the material of impurity and maize meal unloading through a guide chamber, has accomplished the reasonable optimization and the effective integration of function to the device product structure. Because when the impurity is arranged the material, the clear water that falls down by bin gate 13 can continuously erode the inner wall of guide chamber, and the guide intracavity does not have the impurity to remain, has further guaranteed the purity of maize meal.

The drying process is completed after the corn kernels are broken, and the corn flour is subjected to a continuous drying process by the drying oven 39 during the movement of the corn flour along with the conveyor 40. The drying process and the blanking process are carried out simultaneously, so that compared with a treatment mode of cleaning firstly and then drying, the processing time is greatly reduced, and the production and processing period of the corn flour is shortened. In addition, because the corn flour is flatly laid on the conveyor belt 40 in the feeding process, the contact area of the corn flour and the drying unit is large, the drying time is short, and the drying effect is ideal.

The corn grains are not crushed sufficiently, so that the grain size of the corn flour is different, and if the grain size of the corn flour is larger, the quality of the produced corn flour is affected, so that after the drying is finished, the corn flour is fed into a feed box 41 to be screened. In the sieving process, the feed back motor 48 drives the feed back screw rod 50 to rotate, the feed back screw rod 50 drives the left gear 53 and the right gear 54 to rotate, the left gear 53 and the right gear 54 respectively drive the left slider 56 and the right slider 57 to do reciprocating motion in the vertical direction through the connecting rod 55 in the rotating process, and the left slider 56 and the right slider 57 move to drive the feed back screen 42 to do reciprocating motion in the vertical direction. The returning screen 42 effectively disperses the corn flour on the returning screen 42 in the moving process, the corn flour with large particle size is isolated on the returning screen 42, and the corn flour with small particle size falls through the returning screen 42 and is deposited at the bottom of the returning box 41. Through the process, the corn flour can be quickly sorted, the granularity of the sieved corn flour is stable in a proper range, and the quality of the corn flour is guaranteed. When the feed-back screw rod 50 rotates to drive the feed-back screen 42 to reciprocate up and down, the feed-back screw nut 51 moves horizontally along the feed-back screw rod 50, and the pipe clamp 52 and the feed-back pipe 43 thereon move horizontally and synchronously along with the feed-back screw nut 51. When the content of the corn flour loaded on the feed-back screen 42 is large, the feed-back vacuum pump 44 can be started, the corn flour on the feed-back screen 42 is fed into the crushing box 11 by the feed-back vacuum pump 44, and the lower saw teeth 27 crush the corn flour again.

In the mixing stage of the corn flour and the flour, the corn flour and the flour are respectively added into two feeding chambers 621, the powder is sent to a first material spraying device 624 through a spiral feeding rod 623 in the feeding chamber 621, because the bottom of the spiral feeding rod 623 is fixedly connected with a material distribution plate 6241 of the first material spraying device 624, when a feeding motor drives the spiral feeding rod 623 to rotate, the spiral feeding rod 623 drives the first material spraying device 624 to rotate, the powder in the material distribution plate 6241 is sprayed onto a first material mixing sieve plate 63 from a material spraying pipe 6242, sieving treatment is carried out on the first material mixing sieve plate 63, the finer powder directly and uniformly enters each sub-mixing chamber of a first mixing chamber 64 through the material mixing sieve plate, the finer powder is sprayed onto a second material mixing sieve plate 65 through a second material spraying device 646 after primary mixing in the sub-mixing chambers, and enters a crushing/mixing integrated chamber 66 after sieving, the powder with larger particles screened by the first mixing screening plate 63 and the second mixing screening plate 65 is respectively sent into the material receiving bin 631 and the first crushing device 651, the powder in the material receiving bin 631 enters the first crushing device 651 through the powder sending pipe, the powder is crushed in the first crushing device 651, the crushed powder enters the crushing/mixing integrated chamber 66 through the powder outlet pipe, and the finally mixed powder is finally mixed in the crushing/mixing integrated chamber 66.

The invention has the following advantages: staff can once only put the corn-on-cob that needs processing in above-mentioned scheme in steering mechanism's front end, and at steering mechanism to the in-process of lane mechanism pay-off, steering mechanism can be with the corn-on-order of mixed and disorderly random arrangement, makes in the corn-on-cob gets into the processing unit through the lane unit in order. Because need not the staff and frequently place the direction of feed of corn-on-cob and adjustment corn-on-cob, reduce the requirement of staff's amount of labour, very big liberation staff's both hands, design more hommization. In addition, because steering mechanism can overturn the corn-on-cob to its axial and direction of transfer unanimous in the data send process, this just makes the corn-on-cob when getting into the processing unit through lane mechanism, can get into the threshing channel of processing unit approximately perpendicularly in, with the arrangement mode cooperation of threshing channel, does not have the dead angle of threshing, and it is remaining to have the kernel of corn on the corncob, threshes more abundant, and threshes efficiently. In addition, in the threshing process, the corn kernels and the corn cobs can also fall freely under the action of gravity, and the blanking process can also be carried out smoothly. The channel dividing mechanism can divide the straightened corn cobs into an upper channel and a lower channel, and the upper channel and the lower channel are respectively sent into the two feeding holes 1131 of the processing unit. According to the corn cob threshing machine, the threshing rollers 121 are adopted to simultaneously thresh two corn cobs, and the threshing efficiency is obviously improved when more threshing rollers 121 thresh a single corn cob. The invention adopts two paths of materials to be fed simultaneously, after the primary threshing process is finished, the feeding waiting time is avoided, the feeding and threshing processes are tightly connected, the continuity of the device is strong, and the whole processing period is effectively shortened. After threshing is finished, corn kernels are separated from corncobs and from dust and dander, so that the subsequent corn kernel collecting and impurity removing processes are omitted, and the processing period is further shortened. The threshing rollers 121 and the lower screening net 131 are driven by the threshing motor 122 to perform corresponding actions, and a plurality of parts can be driven to move simultaneously by one power source. Because light impurities and dust are separated from the corn kernels before crushing, the purity of the crushed corn flour is high, and the quality is guaranteed. Because no impurities are left on the surface of the corn kernels before the corn kernels are crushed, the crushed corn kernels are cleaner and more sanitary. In addition, before the kernel of corn implements crushing treatment, the rubble that gets into along with the kernel of corn etc. has been picked out, in the product quality after promoting the processing, also can avoid hard thing such as rubble to take place rigid friction with last sawtooth 26 or down between the sawtooth 27, has reduced the wearing and tearing of going up sawtooth 26 or down sawtooth 27, when guaranteeing sawtooth life, also helps guaranteeing the crushing efficiency of sawtooth to the kernel of corn. The clean water washes the bin gate 13, no impurity remains on the bin gate 13, and the purity of the crushed corn flour is high, so that the quality of the corn flour is further ensured. The crushing efficiency can be greatly improved by adopting a segmented crushing mode. In the time of crushing, lift cylinder 21 can also drive and drive sawtooth 26 and lower sawtooth 27 and carry out the up-and-down motion, can also make the sawtooth carry out the breakage to the kernel of corn on the not co-altitude through this mode, and crushing efficiency and crushing effect all improve to some extent. Because the feed back pipe 43 is connected to the feed back nut 51 through the pipe clamp 52, when the feed back nut 51 rotates, the pipe clamp 52 can drive the feed back pipe 43 to move horizontally, so that the corn flour on the feed back screen 42 is completely sent to the chip bin 11. The horizontal movement of the pipe clamp 52 can enable the feed back pipe 43 to suck away the corn flour on the feed back screen 42 at different horizontal positions, the residual amount of the corn flour on the feed back screen 42 is small, and the utilization rate of the raw materials is high. When the material returning motor 48 works, the output shaft of the material returning motor 48 needs to rotate in a positive and negative direction alternatively, so that the material returning screw 51 can drive the pipe clamp 52 to do reciprocating motion in the horizontal direction, and the damage of the material returning motor 48 caused by the fact that the material returning screw 51 is clamped on the material returning screw rod 50 is prevented. Because pipe clamp 52, left slider 56 and right slider 57 all receive the drive of feed back motor 48 to carry out corresponding action, this mode design benefit has reduced the device to the demand of power supply, under the prerequisite of guaranteeing utilization ratio of raw materials and product quality, can effectively reduce the cost of device, do benefit to marketing. Since the screw feed bar 623 is installed in the feeding chamber 621, the flour and corn flour are prevented from being clogged in the feeding chamber 621. Because the first spraying device is arranged at the lower part of the feeding bin 621, powder is sprayed out through the first spraying device, the traditional discharging mode is changed, the discharging is smoother, the sprayed powder is looser, the subsequent powder mixing is facilitated, and the mixing efficiency is improved. Because first mixing chamber 64 is cut apart into a plurality of minutes mixing chambers, the powder is at even distribution to each minute mixing chamber in first mixing chamber 64, carry out preliminary mixing in each minute mixing chamber, because the cutting apart of first mixing chamber 64, the powder is difficult to the misce bene shortcoming when having solved the mixing chamber great, make the powder mix more evenly, it is easier, and the lower part installation second of dividing the mixing chamber spouts material device 646, not only can prevent to divide mixing chamber department powder to block up, further make the powder dispersion, make things convenient for powder mixture and subsequent processing. The setting of first material mixing sieve flitch 63 and second material mixing sieve flitch 65 can screen out the powder of caking, then utilizes first reducing mechanism 651 to smash, avoids the powder of caking to influence the mixed effect between the powder. Finally, due to the arrangement of the crushing/mixing integrated chamber 66, the crushed agglomerated powder and the primarily mixed powder are finally mixed in the crushing/mixing integrated chamber 66, the mixing effect is strengthened, and the second crushing device is arranged in the crushing/mixing integrated chamber 66, so that the powder agglomeration is further avoided, and the subsequent processing is facilitated.
