Description

TECHNICAL FIELD

[0001] The present application relates to the field of wheat flour processing, in particular to a purple waxy whole wheat flour automatic processing equipment and processing method. BACKGROUND

[0002] In modern society, with the enhancement of people's health consciousness, whole grains and foods rich in dietary fiber are increasingly favored by consumers. Purple waxy whole wheat flour is increasingly attracting market attention due to its rich nutritional value and unique taste. However, the existing milling equipment often has problems such as low processing efficiency, high energy consumption, high equipment cost, etc. in the process of processing purple waxy whole wheat flour, which cannot fully meet the market demand for efficient, economical and environmentally friendly processing.

[0003] With the progress of science and technology, relevant field technicians have also optimized the technical means for processing and preparing purple waxy whole wheat flour. In order to make a more accurate comparison, a whole wheat flour processing device and whole wheat flour processing process disclosed in a Chinese patent with publication number CN104923330A includes a flour mill, a powder screening device, a powder storage tank, and a processing classifier, etc. When in use, the processing classifier is used to crush the wheat flour, and the cell wall destruction technology is used to crush the bran and ensure the integrity of the protein in the wheat flour, without reducing the gluten quality of the wheat flour. Only 1 to 2 flour mills and 1 to 2 processing classifiers are needed to process the required whole wheat flour, which reduces the number of flour mills, reduces the size of the equipment, and reduces the investment cost of the equipment, and the processing effect is good.

[0004] However, when using the above-mentioned existing technology to process and handle purple waxy wheat, the following problems still exist:

[0005] The above-mentioned device uses the cooperation between the processing classifier and the flour mill to crush and grind the wheat grains. When using the above-mentioned device to prepare purple waxy whole wheat flour, at least one classifier and one flour mill need to be placed on the ground, so that the grinding and sorting processes of the whole wheat flour can be completed during the processing process. That is, during use, the classifier and the flour mill after use need to be maintained respectively, which does not effectively reduce the equipment investment cost, and the use of at least two devices also occupies a large land area.

[0006] Therefore, under the above-mentioned points, there is still room for optimization in the technical means of the existing technology for processing and handling purple waxy wheat. SUMMARY

DETAILED DESCRIPTION

[0037] The following will be described in detail in combination with the accompanying drawings Figure 1 to the accompanying drawings Figure 9 The embodiments of the application will be described in detail.

[0038] The embodiments of the application disclose a kind of purple waxy wholemeal flour automatic processing equipment and method, the application is mainly applied in the process of grinding processing of purple waxy wheat, and the technical effect is realized to grind purple waxy wheat particles into purple waxy wholemeal flour effect; Especially in the grinding process, only one equipment can complete the effect of sorting and grinding of purple waxy wheat, effectively avoid the problem of occupying large space and increasing equipment cost when processing purple waxy wheat by using multiple equipment;And, the efficiency and effect of grinding and sorting of grain are effectively improved through the mutual cooperation between processing assemblies.

[0039] Embodiment one: refer to Figure 1 and Figure 2 As shown in a kind of purple waxy wholemeal flour automatic processing equipment, including processing cylinder 1, processing cylinder 1 is communicated with feeding channel 10, processing cylinder 1 is provided with the processing assembly 2 for grinding treatment of grain. When using, the purple waxy grain to be treated after pre-washing is introduced into processing cylinder 1 by feeding channel 10, then the automatic grinding treatment effect of grain is realized by the processing of processing assembly 2, so that only one equipment can complete the grinding treatment of grain, effectively reduce the equipment volume for processing purple waxy grain, reduce equipment cost and equipment floor area.

[0040] As shown in processing assembly 2 for grinding treatment of grain, specifically, processing assembly 2 includes: Figures 2 to 4

[0041] ​The temporary storage cylinder 20 is limited in the processing cylinder 1, and the temporary storage cylinder 20 and the processing cylinder 1 are spaced apart by a distance so that the kernels move upward with the airflow, and the temporary storage cylinder 20 is hollow inside to form a temporary storage cavity 21 connected to the feeding channel 10, and the two ends of the temporary storage cylinder 20 separate the processing cylinder 1 into a sorting cavity 22 and a grinding cavity 23.

[0042] The processing end 24 includes at least one grinding roller 240 and a sorting screen 241, and the grinding roller 240 and the sorting screen 241 are respectively limited in the grinding cavity 23 and the sorting cavity 22.

[0043] The connecting ring plate 25 is located in the grinding cavity 23, and the outer edge thereof is limited to be sleeved with a guide plate 250 connected to the processing cylinder 1, and the guide plate 250 is uniformly provided with a plurality of through holes corresponding to the intervals in the circumferential direction, and the connecting ring plate 25, the guide plate 250 and the processing cylinder 1 together form a supplementary air chamber 251 connected to the grinding cavity 23. As an optional embodiment, three grinding rollers 240 are distributed circumferentially on the inner wall of the processing cylinder 1 in this embodiment.

[0044] In use, the cleaned kernels are introduced into the temporary storage cylinder 20 through the feeding channel 10, and then an airflow is blown into the processing cylinder 1, the airflow enters the grinding cavity 23 through the plurality of through holes on the guide plate 250, and then passes through the temporary storage cylinder 20 and is discharged from the sorting cavity 22, the residual water on the pre-cleaned kernels is dried by the flowing airflow, and then the kernels in the temporary storage cavity 21 are introduced into the grinding cavity 23, and the relative displacement between the connecting ring plate 25 and the grinding roller 240 is driven to rotate, thereby achieving the effect of grinding the kernels.

[0045] During the grinding process, the shearing force of the grinding roller 240 acting on the kernels causes the kernels to break and be ground into powder, at this time, the airflow flowing through the supplementary air chamber 251 to the sorting cavity 22 drives the smaller volume of broken kernels in the grinding cavity 23 to rise to the sorting cavity 22, the smaller volume of kernels (i.e. flour) in the rising broken kernels passes through the sorting screen 241 and is then discharged, and the larger volume of broken kernels is blocked by the sorting screen 241 and falls to the temporary storage cylinder 20, which is guided to fall again into the grinding cavity 23 for grinding treatment until the kernels are ground to the required specification, thereby achieving the effect of grinding the purple waxy kernels into whole wheat flour.

[0046] As an optional embodiment, an electric heating device can also be provided in the processing box to make the airflow have a certain temperature when it is output, thereby accelerating the drying efficiency and effect of the cleaned kernels by the flow of low-temperature airflow.

[0047] Reference Figures 2 to 4As shown, the sorting cavity 22, the temporary storage cavity 21, the grinding cavity 23 and the air supplement cavity 251 are sequentially distributed and communicated with each other to form the air flow effect in the processing barrel 1.

[0048] Referring to Figure 3 and Figure 4 As shown, in order to provide the circulating air flow in the processing barrel 1, the connecting ring plate 25 is rotationally limited on the guide plate 250, and the middle part is provided with the driving guide rod 26, and the driving guide rod 26 is connected with the fan 260 located in the air supplement cavity 251. In use, the stable upward air flow is formed in the air supplement cavity 251 by the rotation of the fan 260, so as to realize the effect of air drying treatment of the wheat kernels. At the same time, the rotation of the fan 260 also synchronously drives the driving guide rod 26 and the connecting ring plate 25 to synchronously rotate, so that the relative displacement effect between the connecting ring plate 25 and the grinding roller 240 is formed. After the wheat kernels in the temporary storage barrel 20 fall on the connecting ring plate 25, the connecting ring plate 25 drives the wheat kernels to move to the grinding roller 240 to be ground, thereby realizing the effect of grinding treatment of the wheat kernels.

[0049] Further, referring to Figure 5 and Figure 6 As shown, in order to re-introduce the larger volume of broken wheat kernels blocked by the sorting screen 241 into the grinding cavity 23 for grinding, the upper end of the temporary storage barrel 20 is presented as an upwardly open inclined shape, and the middle part is penetrated to correspondingly communicate the grinding cavity 23 and the sorting cavity 22.

[0050] In use, after rising with the air flow and being blocked by the sorting screen 241, the wheat kernels fall on the upper end of the temporary storage barrel 20, and then re-fall into the grinding cavity 23 along the opening of the temporary storage barrel 20, so as to continue to be ground, thereby increasing the fineness of the ground wheat kernels and the yield of the finished wheat flour.

[0051] Referring to Figure 5 and Figure 6 As shown, the guide plate 250 is provided with an inclined angle, so as to guide the scattered wheat kernels to the connecting ring plate 25.

[0052] Referring to Figure 5 As shown, the sorting screen 241 is rotationally limited on the upper side of the processing barrel 1, and is presented as a conical barrel structure with both ends open, and a plurality of through slots 2410 are uniformly formed on the circumference thereof, for filtering the larger volume of broken wheat kernels. The sorting screen 241 is connected with the driving guide rod 26 through the connecting frame 2411.

[0053] In use, the small particles broken by the grinding cavity 23 are contacted with the sorting screen 241 by the upward airflow. The driving guide rod 26 is driven to rotate synchronously by the rotation of the fan 260. The driving guide rod 26 drives the connecting frame 2411 and the sorting screen 241 to rotate. The larger broken particles in the particles moving upward with the airflow are blocked outside the cylinder of the sorting screen 241 due to the size limitation of the through slots 2410 on the sorting screen 241 and the rotation of the sorting screen 241. The rotation of the sorting screen 241 buffers the upward trend of the larger particles moving upward with the airflow. The broken particles smaller than the size of the through slots 2410 on the sorting screen 241 enter the cylinder of the sorting screen 241. The upward trend of the larger particles is blocked and buffered, and the larger particles are affected by the downward gravity and fall on the upper end of the temporary storage cylinder 20 and then fall back to the grinding cavity 23 to be ground again. The particles in the grinding cavity 23 can pass through the through slots 2410 on the sorting screen 241.

[0054] It should be noted that the rotation of the fan 260 generates upward airflow in the processing cylinder 1. Since the sorting effect of the wheat kernels in the grinding cavity 23 is achieved by the upward airflow, after the air drying of the wheat kernels in the temporary storage cylinder 20 is completed, the output efficiency of the fan 260 as a whole should be reduced by a part, so that the flow rate of the upward airflow is also reduced. The upward airflow flow rate should be maintained in a state that does not drive the complete and partially broken larger volume of wheat kernels to move upward, while allowing the smaller volume of particles to move upward with the airflow.

[0055] The reduction of the rotation rate of the fan 260 reduces the volume of the broken wheat kernels in the grinding cavity 23 that can move upward with the upward airflow, thereby effectively controlling the processing accuracy of the grinding of the wheat kernels. However, the reduction of the rotation rate of the fan 260 also reduces the rotation rate of the sorting screen 241, so that the upward moving wheat kernels are more easily squeezed into the sorting screen 241 by the upward airflow.

[0056] Based on the above, referring to Figure 5 To improve the processing accuracy of whole wheat flour, a secondary screen 27 is arranged in the sorting screen 241 in the sorting cavity 22. The secondary screen 27 is also a conical cylinder structure and uniformly formed with a plurality of through slots 2410 in the circumferential direction. Through the double screening of the sorting screen 241 and the secondary screen 27, the misentry of larger particles is effectively avoided, the screening accuracy is improved, and the problem of reduced sorting efficiency caused by the reduction of the rotation speed of the fan 260 is alleviated to a certain extent. The whole equipment runs more stably and reliably, thereby improving the grinding accuracy of the grinding of the wheat kernels.

[0057] Further, referring to Figure 5As shown, as an optional embodiment, the size of the through slot 2410 on the secondary screen 27 is preferably smaller than that of the through slot 2410 on the sorting screen 241, so as to further improve the screening effect, and effectively block the larger particles squeezed into the cylinder of the sorting screen 241 from passing through, thereby ensuring that only fine particles meeting the requirements can be discharged and collected.

[0058] Referring to Figure 5 As shown, in order to discharge the milled wheat particles from the processing cylinder 1, one end of the secondary screen 27 is open, and the open end is connected to the processing cylinder 1, and a guide channel 11 is formed through the processing cylinder 1 and communicates with the secondary screen 27. In use, the broken wheat particles screened by the sorting screen 241 and the secondary screen 27 are guided by the airflow to between the secondary screen 27 and the processing cylinder 1, and the airflow has a tendency to flow outward along the guide channel 11 after entering the secondary screen 27, thereby driving the smaller volume of purple waxy wheat particles (i.e. milled whole wheat flour) between the secondary screen 27 and the processing cylinder 1 to be discharged outward at the same time, so as to be uniformly collected by the staff.

[0059] Embodiment two: referring to Figures 5 to 7 As shown, on the basis of embodiment one, before the wheat particles are milled, it is usually necessary to remove impurities from the wheat particles by water washing or water soaking, and then the dried wheat particles after impurity removal are put into the equipment for milling treatment, so as to improve the output quality of the purple waxy whole wheat flour. In order to complete the air drying effect of the pre-washed wheat particles, the temporary storage cylinder 20 includes an installation ring plate 200 and a guide ring plate 201 spaced apart upward, the installation ring plate 200 is an upward open inclined plate connected to the guide channel 11, the guide ring plate 201 is an inclined bent plate, and a plurality of air vents 202 are uniformly arranged on the guide ring plate 201, so as to allow the rising airflow in the air supply cavity 251 to escape. The installation ring plate 200 and the guide ring plate 201 are jointly limited by a connecting cylinder 203, and a temporary storage cavity 21 is formed between the installation ring plate 200, the guide ring plate 201 and the connecting cylinder 203. The connecting cylinder 203 is connected to the opening of the sorting screen 241, so that the milling cavity 23 and the sorting cavity 22 are connected, and the broken wheat particles blocked by the sorting screen 241 fall back into the milling cavity 23.

[0060] In order to guide the dried wheat particles in the temporary storage cavity 21 into the milling cavity 23, a plurality of through grooves 204 are formed on the connecting cylinder 203, a sliding blocking plate 28 is slidably inserted into the connecting cylinder 203 corresponding to the through grooves 204, a driven guide plate 280 extends from the sliding blocking plate 28 into the temporary storage cavity 21, an installation seat 281 is connected to the driven guide plate 280, a rotating pin 282 is arranged on the installation seat 281, the rotating pin 282 is limited on the installation seat 281 by a torsional spring, and a limiting plate 283 is connected to the rotating pin 282 to limit the deflection amplitude of the rotating pin 282.

[0061] In use, after the pretreated and cleaned wheat kernels are introduced into the temporary storage cavity 21 through the feeding channel 10, the fan 260 is started to form an air flow in the processing cylinder 1, which passes through the grinding cavity 23 and the sorting cavity 22 from the air supplement cavity 251, and is then discharged outward through the guide channel 11. When the air flow passes through the space between the guide ring plate 201 and the mounting ring plate 200 and the processing cylinder 1, it escapes into the temporary storage cavity 21 through the air holes 202 on the guide ring plate 201. After the air flow passes through the wheat kernels in the temporary storage cavity 21, the moisture in the wheat kernels is accelerated to evaporate, thereby achieving the effect of drying the pretreated and cleaned wheat kernels.

[0062] After the drying of the wheat kernels is completed, the driven guide plate 280 and the sliding blocking plate 28 slide along the connecting channel 204, and the connecting channel 204 partially leaks, so that the temporary storage cavity 21 is connected with the grinding cavity 23 and the sorting cavity 22 through the air holes 202 and the connecting channel 204. At this time, due to the guidance of the guide ring plate 201 and the gravity of the wheat kernels, the wheat kernels in the temporary storage cavity 21 have a tendency to slide along the inclined guide ring plate 201 to the connecting channel 204, so that the wheat kernels fall from the connecting channel 204 to the connecting ring plate 25, and then are moved to the grinding roller 240 to be extruded and ground by the rotating connecting ring plate 25. The smaller volume of the broken wheat kernels after being ground by the grinding roller 240 is moved upward to the sorting cavity 22 by the air flow, and the smaller volume of the particles that meet the specifications enter the secondary screen 27 to be guided and discharged. The larger volume of the particles is blocked and falls back to the connecting ring plate 25 to be ground again until they meet the requirements.

[0063] Further, as shown in Figures 6 to 9 Since the wheat kernels need to be pretreated and cleaned, the weight of the wheat kernels will increase after being soaked, and the weight of the dried wheat kernels will decrease due to the loss of moisture. In order to drive the sliding blocking plate 28 to slide and introduce the dried wheat kernels in the temporary storage cavity 21 into the grinding cavity 23, a bent pressing plate 29 is connected between any two adjacent driven guide plates 280. The bent pressing plate 29 is connected with an extension guide rod 290 that penetrates the guide ring plate 201, and a driven face plate 291 in the grinding cavity 23 is connected between the extension guide rods 290.

[0064] In the initial state, the sliding blocking plate 28 normally slides and is limited in the corresponding connecting channel 204 to close the temporary storage cavity 21. At this time, the bent section at the bottom of the bent pressing plate 29 is spaced apart from the guide ring plate 201 by a distance, the driven guide plate 280 and the mounting seat 281 are spaced apart from the guide ring plate 201 by a distance, the rotating pin 282 and the limiting plate 283 are deflected by a certain amplitude, the limiting plate 283 is inclined and is arranged at a certain angle between the driven guide plate 280, and the limiting plate 283 abuts against the guide ring plate 201.

[0065] When in use, the pretreated wheat grains are introduced into the temporary storage cavity 21, and the falling wheat grains first fall on one of the driven guide plates 280 and apply a downward pushing force to the driven guide plate 280, so as to drive the driven guide plate 280, the sliding blocking plate 28, the mounting seat 281, the rotating pin 282, the limiting plate 283 and the bent pressing plate 29 to further move downward until the bent pressing plate 29 abuts against the guide ring plate 201, the limiting plate 283 and the connected rotating pin 282 are further rotated and inclined, and the connected torsion spring is further stressed, the wheat grains falling into the temporary storage cavity 21 are affected by their own gravity and naturally gathered towards the connecting cylinder 203 along the guide ring plate 201, so as to be accumulated on the bent pressing plate 29, and the bent section at the bottom end of the bent pressing plate 29 abuts against the guide ring plate 201 to limit the upward movement of the driven guide plate 280, the sliding blocking plate 28, the mounting seat 281, the rotating pin 282, the limiting plate 283 and the bent pressing plate 29.

[0066] When the pretreated wheat grains need to be dried at the initial stage, the output efficiency of the fan 260 is increased at this time, so that the flow rate of the airflow flowing in the processing cylinder 1 is increased, the airflow rises to the grinding cavity 23 and contacts the driven face plate 291, which has a tendency to move upward with the airflow, while the bent pressing plate 29, the extension guide rod 290 and the driven face plate 291 are limited by the accumulated wheat grains in the temporary storage cylinder 20 and cannot move upward, so that the torsion spring is always in a stressed state.

[0067] After the wheat grains in the temporary storage cylinder 20 are dried, the weight of the whole wheat grains is reduced due to the loss of their own moisture, and the downward pressing force applied to the whole of the bent pressing plate 29, the driven guide plate 280, the sliding blocking plate 28, the mounting seat 281, the rotating pin 282 and the limiting plate 283 is reduced, at this time, under the joint action of the upward airflow and the resetting force of the torsion spring, the whole of the bent pressing plate 29, the driven guide plate 280, the sliding blocking plate 28, the mounting seat 281, the rotating pin 282, the limiting plate 283, the extension guide rod 290 and the driven face plate 291 moves upward, so as to open the through slot 204 on the connecting cylinder 203, so that the wheat grains fall into the grinding cavity 23, and after the wheat grains in the temporary storage cavity 21 completely fall, the output efficiency of the fan 260 is reduced, so as to sort the ground wheat grains.

[0068] Further, with reference to Figure 6 and Figure 7As shown, as an optional embodiment, in order to improve the drying efficiency of the corns in the temporary storage cavity 21, the connecting cylinder 203 is also connected with the driving guide rod 26 through the connecting frame 2411, at this time, the connecting cylinder 203 is rotationally connected with the mounting ring plate 200 and the guide ring plate 201, the plurality of extension guide rods 290 slide through the guide ring plate 201, and the plurality of extension guide rods 290 are jointly connected with the closing ring plate (not shown in the figure) which slides through the guide ring plate 201, so as to avoid the leakage of the corns during the rotation.

[0069] In use, after the fan 260 is started, it drives the connecting cylinder 203 to rotate through the driving guide rod 26, the connecting cylinder 203 drives all the connected sliding blocking plates 28, driven guide plates 280, mounting seats 281, rotating pins 282, limiting plates 283, bent pressing plates 29, extension guide rods 290, closing ring plates and driven face plates 291 to rotate synchronously, so that the limiting plates 283 and the sliding blocking plates 28 drive the corns in the temporary storage cavity 21 to move, thereby increasing the contact area of the corns and the airflow and improving the drying efficiency of the corns.

[0070] In addition, the application also provides an automatic processing method for purple waxy whole wheat flour, which comprises the following steps:

[0071] S1: The pre-washed purple waxy wheat particles are introduced into the temporary storage cylinder 20 through the feeding channel 10, and then the corns in the temporary storage cylinder 20 are dried by the processing assembly 2.

[0072] S2: After the drying treatment of the corns is completed, the corns are driven to fall into the grinding cavity 23, and then the corns are ground by the cooperation between the grinding roller 240, the connecting ring plate 25 and the guide plate 250.

[0073] S3: After the corns are ground, the broken wheat particles are transported into the sorting cavity 22 for screening, the broken particles meeting the screening specifications of the sorting screen 241 are guided to be discharged, and the broken particles not meeting the specifications are re-fallen into the grinding cavity 23 for continuous grinding until meeting the specifications.

[0074] The embodiments of the specific embodiments are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
