Abstract
Description
Technical Field
[0001] This invention relates to the field of soybean protein processing technology, specifically to a drying apparatus and method for soybean protein processing. Background Technology
[0002] Soy protein is a protein extracted from soybeans, usually existing in powder form. It is a high-quality plant protein source, rich in amino acids, and an important protein source for vegetarians and some people allergic to animal protein. Soy protein is often used in various food manufacturing processes, including plant-based meat substitutes, soy milk, tofu, and nutritional supplements. It is also widely used in the food industry as an ingredient to increase protein content or improve texture. Soy protein is in liquid form after extraction from soybeans and needs to undergo multiple processing steps to finally form it into powder. Currently, the main methods for drying it include spray drying, rotary drying, fluidized bed dryer, and microwave drying.
[0003] However, these drying methods are relatively simple and have limited drying effects. For example, in rotary drying, the soybean protein is turned over by spiral blades in a drum. When it is turned over, the soybean protein accumulates in a thick layer, which prevents heat from penetrating into the inner soybean protein. As a result, the soybean protein cannot be completely dried, and the dried soybean protein powder is relatively heavy.
[0004] During spray drying, some of the dried, viscous soy protein may clump together and harden into lumps. The system cannot break up these clumps in time, causing them to accumulate in the heating equipment and reducing drying performance. Furthermore, because the soy protein remains in a closed container throughout the drying process, some fully dried soy protein cannot be sieved out in time and mixes with the subsequently sprayed, moist soy protein. This repeated drying process prolongs the drying time and slows down the drying speed. Summary of the Invention

[0013] A drying method for soybean protein processing, using a soybean protein processing drying device, includes the following steps:

[0018] As can be seen from the above technical solutions, the present invention has the following advantages:
[0019] In this invention, the combination of an arc-shaped material distribution strip, a material leveling rod, and a rotating material spreading disc in a ring allows the soybean protein to be evenly spread from the inside out under centrifugal force, ensuring that the soybean protein can be heated evenly, dried more thoroughly, and improving the drying effect.
[0020] In this invention, the upward-spraying hot air blows the No. 1 fan blade to rotate, which in turn drives the grinding disc to rotate. This facilitates the timely crushing of clumps of soybean protein, avoids the accumulation of soybean protein, and speeds up the drying process.

[0022] In this invention, multiple drying methods for soybean protein are achieved by combining spray drying and rotary drying, which can greatly improve the drying effect and accelerate the drying speed. Attached Figure Description

Detailed Implementation
[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0039] Please see Figure 1 The present invention provides a technical solution: a drying device for processing soybean protein, including a processing base 1, a self-crushing drying mechanism 2 for crushing clumps of soybean protein that occur during the drying process is installed on the front of the upper end of the processing base 1 via a bracket, and a rotary drying mechanism 3 for flattening soybean protein during the drying process is installed on the rear of the upper end of the processing base 1 via a connecting frame, and the self-crushing drying mechanism 2 and the rotary drying mechanism 3 are connected by a connecting part 4.
[0040] Please see Figure 1 , Figure 6 , Figure 7 and Figure 8In this embodiment, the self-crushing and drying mechanism 2 includes a second processing cylinder 21 fixedly connected to the support and open at the bottom. A feed component 22 is provided at the top of the second processing cylinder 21. An annular disk 23 is fixedly connected to the inner cavity of the second processing cylinder 21. An annular cylinder 24 is rotatably connected to the inner wall of the annular disk 23. Several shafts are equidistantly rotatably connected to the outer circumference of the annular cylinder 24. Several crushing discs 25 are equidistantly fixed to the outer axial direction of each shaft. Several scrapers 26 are equidistantly fixed to the outer circumference of the annular cylinder 24. A first fan blade 27 is fixedly connected to the inside of the annular cylinder 24 via a vertical column. A conical diverter block 28 is fixedly connected to the upper end of the vertical column. The conical surface of the conical diverter block 28 guides and diverts the rising hot air, dispersing the hot air to increase the contact area with the soybean protein solution. A pointed cap is fixedly connected to the upper end face of the conical diverter block 28. The conical surface of the pointed cap helps to prevent incompletely dried soybeans from falling off. Soy protein rolls onto the annular disk 23. The annular disk 23 has several L-shaped channels 29 evenly spaced along its inner circumference. The upper part of the annular disk 23 has several sets of vertical holes 210 evenly spaced along its radial direction. These vertical holes 210 are arranged in several rows evenly spaced along the circumference of the annular disk 23, corresponding to the L-shaped channels 29. Each set of vertical holes 210 corresponding to the L-shaped channels 29 is connected to the transverse section of the L-shaped channels 29. Several vent pipes 211 are circumferentially embedded in the second processing cylinder 21. The upper part of the self-crushing and drying mechanism 2 is symmetrically provided with discharge ports 212. Each discharge port 212 is equipped with a pusher component 2a to discharge the dried soybean protein. The feed component 22 includes a feed main pipe 221 that runs through the upper part of the second processing cylinder 21. Several branch pipes 222 are equidistantly connected to the lower part of the feed main pipe 221. Each branch pipe 222 is connected to a nozzle 223 at its lower end. A conical cover 224 is fixedly connected to the outside of the branch pipes 222.
[0041] Hot air generated by an external air pump is introduced into the lower opening of the second processing cylinder 21, while soybean protein solution is introduced into the feed main pipe 221. The soybean protein solution then enters the branch pipe 222 for diversion, and is then atomized and sprayed out from the nozzle 223. The hot air flows from bottom to top in the second processing cylinder 21. During the flow of hot air, part of it enters the L-shaped channel 29, then enters the vertical hole 210 and continues to flow upward. The other part of the hot air flows in from the space in the annular cylinder 24 and flows upward through the annular cylinder 24. The upward flowing hot air comes into contact with the atomized soybean protein solution to dry the soybean protein solution. The dried soybean protein powder flows upward from the space outside the conical hood 224 and enters the discharge port 212. During the drying process, some of it accumulates in one... The partially dried soybean protein falls onto the annular disc 23. The hot air flowing through the annular cylinder 24 drives the first fan blade 27 to rotate, which in turn drives the annular cylinder 24 to rotate. The annular cylinder 24 then drives the crushing disc 25 to roll on the annular disc 23 via the shaft, breaking up the clumps of soybean protein. The crushed soybean protein then comes into contact with the hot air exiting from the vertical hole 210 for further drying. The rotating annular cylinder 24 then drives the scraper 26 to rotate synchronously. The inclined surface of the scraper 26 scoops up the soybean protein dried on the surface of the annular disc 23 and moves it along the inclined surface. The moved soybean protein then moves upward under the influence of the upward flowing hot air and enters the discharge port 212. This process can promptly crush and dry the clumps of soybean protein into powder, ensuring the normal drying function of the self-crushing and drying mechanism 2.
[0042] Please see Figure 9 , Figure 10 and Figure 11In this embodiment, the feeding component 2a includes a rectangular frame 2a1 fixedly connected to the upper part of the second processing cylinder 21 and communicating with the discharge port 212. A filter membrane 2a2 is fixedly connected in the rectangular frame 2a1. A strip groove 2a3 is opened at the front of the rectangular frame 2a1. A slider 2a4 located below the filter membrane 2a2 is slidably connected in the strip groove 2a3. Elastic sealing strips 2a5 are fixedly connected to both the upper and lower walls of the strip groove 2a3. The upper and lower elastic sealing strips 2a5 deform and abut against each other to fill the strip groove 2a3, preventing the dried soybean protein powder from flowing out of the strip groove 2a3. At the same time, during the movement of the slider 2a4, the slider 2a4 is squeezed and deformed at the contact point with the slider 2a4, ensuring the normal movement of the slider 2a4. Scraper blades 2a6 that fit against filter membrane 2a2 are fixedly connected to the left and right sides of strip 2a4. Rotating columns are symmetrically connected to the front end of rectangular frame 2a1 through a fixed plate. Moving belts 2a7 are externally connected to the two rotating columns. Rectangular telescopic columns are fixedly connected to the front end of slide bar 2a4. Rectangular telescopic columns are hinged to moving belts 2a7 through hinged columns 2a8. Second fan blades 2a9 are rotatably connected to the upper end of rectangular frame 2a1 through L-shaped rods. Second fan blades 2a9 are connected to one of the rotating columns through a transmission belt 2a10. Discharge troughs 2a11 are opened on the left and right walls of rectangular frame 2a1. Baffles 2a12 are hinged to the channels of discharge troughs 2a11 through hinged rods and torsion springs. Top columns 2a13 that cooperate with baffles 2a12 are fixedly connected to the left and right sides of slide bar 2a4.
[0043] Please see Figure 6 The connecting part 4 includes two C-shaped tubes 41 respectively fitted outside the rectangular frame 2a1, and two parallel branches of the C-shaped tubes 41 are connected to the discharge trough 2a11. The rear part of the C-shaped tubes 41 is connected to an inclined tube 42. The upper part of the first processing cylinder 31 is symmetrically provided with feed holes 5 corresponding to the inclined tubes 42, and the rear end of the inclined tubes 42 is connected to the feed holes 5.
[0044] The pore size of the filter membrane 2a2 only allows hot air to pass through, while the soybean protein powder entering the outlet 212 is intercepted by the filter membrane 2a2. The hot air flowing from the outlet 212 continues to rise into the rectangular frame 2a1, which then drives the second fan blade 2a9 to rotate. The rotation of the second fan blade 2a9, in turn, drives the rotating column to rotate via the transmission belt 2a10. The rotating column then drives the moving belt 2a7 to rotate. As the moving belt 2a7 moves along the waist-shaped path, it drives the rectangular telescopic column to move via the hinged column 2a8, which in turn drives the slide bar 2a4 to move laterally back and forth in the strip groove 2a3. During the lateral back and forth movement of the slide bar 2a4, it drives the scraper 2a6 to move under the filter membrane 2a2 to scrape away the soybean protein powder that has been intercepted after drying. The scraper 2a6 scrapes the soybean protein powder towards the discharge trough 2a11. As the slide bar 2a4 moves the scraper 2a6 into the discharge trough 2a11, the top column 2a13 touches the baffle 2a12, which in turn rotates along the hinge point between the baffle 2a12 and the bottom of the discharge trough 2a11. Then the scraper 2a6 pushes the soybean protein powder into the discharge trough 2a11, thus enabling timely collection of the dried soybean protein powder and avoiding repeated drying. The soybean protein powder pushed into the discharge trough 2a11 then enters the C-shaped tube 41 connected to the discharge trough 2a11. The bottom of the C-shaped tube 41 is inclined backward, so the soybean protein powder then moves backward into the inclined tube 42, and then into the feed hole 5.
[0045] Please see Figure 2 and Figure 3 In this embodiment, the rotary drying mechanism 3 includes: a first processing cylinder 31 fixedly connected to a connecting frame; a concave spreading disc 33 rotatably connected to the inner cavity of the first processing cylinder 31 via a drive ring 32; a plurality of sets of arc-shaped material dividing strips 35 rotatably connected to the spreading disc 33 via a rotating shaft 34; each set of arc-shaped material dividing strips 35 is arranged radially; and a plurality of corresponding arc-shaped material dividing strips 35 are equidistantly installed at the lower part of the spreading disc 33, which are used to adjust the arc-shaped material dividing strips. The turning component 36 at the position of the material bar 35 has an arc-shaped material distribution bar 35 with gradually increasing height from the inside to the outside and arranged in a stepped manner. Several material distribution rods 37 are fixedly connected at equal intervals on the inner wall of the first processing cylinder 31 and directly above the material distribution plate 33. An annular heating plate 38 is fixedly connected to the inner cavity of the first processing cylinder 31 and directly below the material distribution plate 33. A through hole 310 is opened in the middle of the material distribution plate 33. The through hole 310 and the bottom of the cavity of the first processing cylinder 31 are jointly installed with the material discharge control component 39.
[0046] Please see Figure 3 and Figure 4The reversing assembly 36 includes a strip frame 361 fixedly connected to the outside of the rotating shaft 34. A sliding column 362 is slidably connected in the strip frame 361. A lever 363 is fixedly connected to the lower end of the sliding column 362. An annular groove 364 is opened on the inner circumference of the second processing cylinder 21. A slider 365 is slidably connected in the annular groove 364. The slider 365 is fixedly connected to the end of the lever 363. A number of notched rings 366, which are sleeved on the outside of the rotating shaft 34 and used to cooperate with the strip frame 361, are fixedly connected at equal intervals along the radial direction of the lower surface of the material spreading disc 33 by fixed columns.
[0047] Please see Figure 5 The material control assembly 39 includes several L-shaped plates 391 circumferentially and equidistantly fixed to the wall of the through hole 310. A rotating shaft 392 is rotatably connected to the vertical section of each L-shaped plate 391. A sector-shaped plate 393 is fixedly connected to the outside of the rotating shaft 392 via a connecting block. A gear 394 is fixedly connected to the end of the rotating shaft 392 furthest from the center of the through hole 310. A circular hole is opened at the bottom of the first processing cylinder 31, and an annular groove 395 is opened in the circular hole. An L-shaped rod 396 is slidably connected in the middle. An annular seat 397 is fixedly connected to the upper part of the L-shaped rod 396. The annular seat 397 has several arc-shaped through slots 398 that correspond to the L-shaped plate 391 and are penetrated by the transverse section of the L-shaped plate 391. Several racks 399 that correspond to and mesh with the gear 394 are fixedly connected to the upper part of the annular seat 397. Limiting strips 3910 are symmetrically fixedly connected to the upper end face of the racks 399.
[0048] Soy protein powder entering the inclined tube 42 then enters the first processing cylinder 31 through the feed hole 5, and subsequently falls onto the spreading disc 33. When the soybean protein powder accumulates to a certain extent on the spreading disc 33, the control drive ring 32 drives the spreading disc 33 to rotate. At this time, the arc-shaped material distribution strips 35 in the circumferential position are spliced together to form a complete circle, while the fan-shaped plates 393 in the discharge control assembly 39 are spliced together. The centrifugal force generated during the rotation of the spreading disc 33 causes the soybean protein powder to gradually move from the inside to the outside along the upper surface of the spreading disc 33. During the process, the arc-shaped material distribution bar 35 scrapes the lower part of the soybean protein powder, so that the soybean protein powder is evenly spread on the spreading tray 33. At the same time, some thicker areas will move with the rotation of the spreading tray 33, and then come into contact with the uniform material rod 37 and be scraped by the uniform material rod 37, further spreading on the spreading tray 33. During the rotation of the spreading tray 33, the annular heating plate 38 is energized to make it run and generate heat, which heats the spread soybean protein powder, so that the soybean protein powder can be heated evenly and the drying effect is improved.
[0049] After drying, the drive ring 32 is controlled to rotate in the opposite direction, which in turn drives the spreading disc 33 to rotate in the opposite direction by a certain angle. During the reverse rotation of the spreading disc 33, the slider 365 rotates in the annular groove 364. The slider 365 and the annular groove 364 are interference fit, so the slider 365 needs to overcome a large resistance when rotating. During this process, the spreading disc 33 drives the strip frame 361 to abut against the sliding column 362 through the rotating shaft 34, which in turn causes the strip frame 361 to drive the rotating shaft 34 to rotate until the circumferentially adjacent arc-shaped material distribution strips 35 separate from each other and become inclined. Then the strip frame 361 stops rotating when it abuts against the end of the notched ring 366. Then the spreading disc 33 can drive the slider 365 to slide in the annular groove 364. After the deflection, the arc-shaped material distribution strips 35 lose their blocking effect on the spread soybean protein powder. Therefore, the soybean protein powder then flows and gathers towards the center of the spreading disc 33 under the slope of the conical upper surface of the spreading disc 33.
[0050] While the reversing component 36 drives the arc-shaped material distribution ring to deflect, the discharge component 39 operates synchronously. The L-shaped rod 396 and the annular groove 395 are also interference-fitted, resulting in a large frictional resistance between the L-shaped rod 396 and the annular groove 395. When the material spreading disc 33 rotates in the reverse direction, it drives the L-shaped plate 391 to rotate synchronously. The L-shaped plate 391 then drives the rotating shaft 392 to rotate synchronously. The rotating shaft 392 then drives the gear 394 to rotate synchronously and meshes with the gear 394 to rotate itself. The rotating gear 394 then drives the sector plate 393 to rotate through the rotating shaft 392, causing the spliced sector plates 393 to rotate and separate. At this time, the gear 394 stops rotating when it abuts against the limit bar 3910. The rotating material spreading disc 33 then pushes the annular seat 397 to rotate synchronously through the gear 394 abutting against the limit bar 3910.
