Description

Technical Field

[0001] The present invention relates to the field of bean dregs processing, and in particular to a device and a method for producing vegetable protein from bean dregs. Background Art

[0002] Bean dregs, as the main by-product of soy product processing, come from the residue in the production process of tofu, soy milk, etc. It is rich in plant protein and rich in nutrients such as dietary fiber, calcium, and iron. However, if the bean dregs are used directly, the anti-nutritional factors such as antitrypsin contained in it will affect the digestion and absorption of protein. Therefore, microbial fermentation technology is mainly used to degrade these factors and improve its availability as a plant protein resource.

[0003] Fermentation is a key technology for converting soybean dregs into high-nutritional plant protein, suitable for large-scale production. The fermentation process includes raw material pretreatment: mixing fresh soybean dregs with auxiliary materials in appropriate proportions; adding fermentation agents: adding specific microbial fermentation aids to release protein activity; and sealed fermentation: fermenting in an anaerobic environment to promote microbial metabolic activity. Agitation is essential in the fermentation of soybean dregs to produce plant protein, and its specific implementation needs to be adjusted according to the different fermentation stages. In the early stages of fermentation, the materials must be thoroughly mixed to promote the rapid growth of mesophilic microorganisms (Mucor and Rhizopus) and accelerate the decomposition of anti-nutritional factors. In the middle stages of fermentation, the surface layer should be gently stirred to avoid disrupting the established mycelial network and maintain the continuous action of proteases. In the late stages of fermentation, agitation is discontinued and the fermentation chamber is kept sealed and undisturbed.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a device for producing plant protein from bean dregs, comprising a fermentation box 100, a dregs turning mechanism 300, and a dregs covering assembly 200. The fermentation box 100 stores fermented bean dregs, and the dregs turning mechanism 300 is used to gently turn the surface of the bean dregs in the middle stage of fermentation to achieve partial exchange of the surface and bottom materials while avoiding damage to the mycelial network structure formed at the bottom. The dregs covering assembly 200 cooperates with the dregs turning mechanism 300 to receive and re-cover the surface bean dregs, and temporarily places the turned bean dregs on the dregs covering assembly 200. like Figure 9 As shown, the fermentation box 100 includes a box body 101. A fermentation chamber is provided inside the box body 101. One side of the box body 101 is uncovered. Figure 10 As shown, a sealing groove 103 is provided on the uncovered side of the box body 101, and a sealing side plate 102 is detachably mounted on the sealing groove 103. Figure 11 and Figure 12As shown, a sealing member 104 is provided on the sealing side panel 102, and the sealing member 104 includes a sealing rubber ring. The sealing side panel 102 is sealedly connected to the sealing groove 103 through the sealing rubber ring thereon. The bottom of the box body 101 can also be removably provided with a sealing top cover (not shown in the figure), and the sealing top cover and the box body 101 are also sealed. When in use, the pretreated bean dregs are placed in the fermentation box 100, and then the sealing side panel 102, the box body 101 and the sealing top cover are sealed. In addition to the sealing rubber ring, the sealing side panel 102 and the sealing top cover are also provided with a limiting bolt for tightly connecting the sealing side panel 102 and the sealing top cover to the box body 101 to ensure their sealing. The limiting bolt in this embodiment includes a limiting ring and a limiting pin. The limiting ring can be fixedly installed in the box body 101, and the limiting pin can be slidably provided on the sealing side panel 102 and the sealing top cover. The limiting bolt in this embodiment is provided with several groups according to actual conditions. At the same time, in addition to using the limiting bolt to limit the position in this embodiment, bolt fixing and other methods can also be used.

[0025] During actual operation, the pretreated bean dregs need to be put into the fermentation box 100 for fermentation treatment, but the pretreated bean dregs may be agglomerated. If they are not crushed, incomplete fermentation may occur at the agglomerated areas, affecting the final fermentation quality. Therefore, in this embodiment, a slag covering component 200 is used to crush and discharge the pretreated bean dregs, wherein the crushing process needs to be synchronized with the slag turning mechanism 300, and the slag covering component 200 in this embodiment is used to input fermentation raw materials such as wheat bran, and its use is consistent with the principle of inputting bean dregs.

[0026] like Figure 6 As shown, the slag covering component 200 includes a fixed seat 201, a slide groove 202 is opened on the fixed seat 201, a first telescopic cylinder 205 is slidably provided in the slide groove 202, a first limiting rod 203 is fixed on the slide groove 202, and a first threaded rod 204 is also slidably provided on the slide groove 202, and the first threaded rod 204 is threadedly matched with the first telescopic cylinder 205, and the first limiting rod 203 is slidably connected to the first telescopic cylinder 205, wherein one end of the first threaded rod 204 is connected to a first motor, which is fixed in the fixed seat 201, and the first threaded rod 204 is driven to rotate by the first motor to further realize the movement of the first telescopic cylinder 205 in the slide groove 202, and a first connecting plate 206 is fixed on the output end of the first telescopic cylinder 205, and a collection frame is detachably provided on the first connecting plate 206, as shown in FIG. Figure 7 As shown, the collecting frame includes a frame 207, a chamber is provided inside the frame 207, and the top and bottom ends of the frame 207 are both in an uncovered state, that is, the upper and lower ends of the frame 207 are penetrated, a large-aperture screen 209 is fixedly provided at the bottom of the frame 207, and a supporting plate 208 is also slidably provided on the frame 207 below the screen 209. Figure 8As shown, a track groove 210 is fixedly provided at the bottom of the frame 207, and the supporting plate 208 is slidably fitted with the track groove 210. When in use, the pretreated bean dregs are poured into the collecting frame, and then the first threaded rod 204 is driven to rotate by the first motor, and the collecting frame is raised to a certain height in conjunction with the first telescopic cylinder 205. When the collecting frame rises and moves to the upper end position of the fermentation box 100, the supporting plate 208 is pulled away from the bottom of the frame 207. At this time, only the large-aperture screen 209 is left at the bottom of the frame 207. At this time, the bean dregs in the frame 207 can be moved to achieve uniform falling of the bean dregs, and the agglomerated bean dregs after pretreatment can be crushed and fall evenly. The crushing process can be achieved in conjunction with the slag turning mechanism 300.

[0027] During the fermentation process, bean dregs need to be turned differently according to different fermentation stages. In the early stage of fermentation, they need to be thoroughly turned and stirred to promote the rapid reproduction of mesophilic microorganisms and accelerate the decomposition of anti-nutritional factors. In the middle stage of fermentation, they need to be moved slowly in one direction and the surface layer needs to be turned gently to avoid damaging the formed mycelium network and maintain the continuous action of proteases. In addition, an oblique insertion method needs to be adopted during the turning of the surface layer to avoid vertical downward shear force that damages the formed mycelium. In the late stage of fermentation, stirring needs to be stopped and the bean dregs need to be kept sealed and allowed to stand. In response to the different turning requirements in the fermentation stages, the dregs turning mechanism 300 is used in this embodiment to turn the bean dregs at different stages.

[0028] like Figure 2 As shown, the slag turning mechanism 300 includes a side bracket 301, which is L-shaped, one end of the side bracket 301 is fixedly connected to the fixing seat 201, and the other end is fixedly rotatably provided with a mounting bracket 302, a second motor 303 is fixedly provided on the side bracket 301, the output end of the second motor 303 is fixedly connected to the mounting bracket 302, and the rotation of the mounting bracket 302 is driven by the second motor 303, the mounting bracket 302 is U-shaped, a second threaded rod 304 is rotatably provided on the mounting bracket 302, a second limiting rod 305 is fixedly provided on the mounting bracket 302, a third motor 306 is fixedly provided on the mounting bracket 302, the output end of the third motor 306 is fixedly connected to the second threaded rod 304, the third motor 306 drives the second threaded rod 304 to rotate, and the second threaded rod 304 rotates, as shown in FIG. Figure 4 As shown, the slag turning mechanism 300 also includes two independent moving seats 307 of the device, one of which is threadedly matched with the second threaded rod 304, and the other is slidingly matched with the second limiting rod 305. A mounting block 308 is rotatably provided between the two moving seats 307. The rotational connection between the two moving seats 307 and the mounting block 308 is driven by a fourth motor. A second telescopic cylinder 309 is fixed on the mounting block 308. A transverse mounting plate 310 is fixed on the output end of the second telescopic cylinder 309. A convex plate 311 is fixed on one side of the transverse mounting plate 310, and a thin plate 312 is rotatably provided on the other side of the transverse mounting plate 310. Figure 5 As shown, first connecting members 320 are fixedly provided on both sides of the thin plate 312, and rotating shafts 321 are rotatably provided at both ends of the horizontal mounting plate 310. The rotating shafts 321 on both sides are fixedly connected to the two first connecting members 320, and a fifth motor (not shown in the figure) is connected to the rotating shaft 321. The rotation of the thin plate 312 is achieved by the fifth motor, and a side baffle 322 is fixedly provided at the top end of the horizontal mounting plate 310.

[0029] like Figure 2 and Figure 3 As shown, a mounting groove 326 is provided on the convex plate 311, and two first pulleys 318 are rotatably provided on the mounting groove 326. The two first pulleys 318 are connected by a first synchronous belt 319, one of the first pulleys 318 is connected to a sixth motor 317, and the sixth motor 317 is fixedly connected to the convex plate 311, and a second pulley 324 is coaxially and fixedly provided on the other first pulley 318. A second pulley 324 is also provided on the convex plate 311 outside the mounting groove 326. The two second pulleys 324 are synchronously connected by a second synchronous belt 325. A third threaded rod 313 is installed on the two second pulleys 324, and the two third threaded rods 313 are coaxially and fixedly connected to the two second pulleys 324 respectively. That is, when the sixth motor 317 rotates, the first synchronous belt 319 is used to realize the synchronous rotation of the two first pulleys 318, and then the second synchronous belt 325 is used to realize the synchronous rotation of the two second pulleys 324, and finally the synchronous rotation of the two third threaded rods 313 is realized. Figure 4 As shown, the two third threaded rods 313 are threadedly fitted with a second connecting piece 314, and the two second connecting pieces 314 are fixedly connected to the top bracket 315. The two top brackets 315 are detachably provided with a plurality of insertion rods 316. The plurality of insertion rods 316 are linearly arrayed, and the plurality of insertion rods 316 are slidably fitted with the horizontal mounting plate 310. The third threaded rod 313 can realize the up and down movement of the plurality of insertion rods 316. The side baffle 322 is also fixed with a plurality of fixing rings 323. When in use, the plurality of insertion rods 316 will come into contact with the bean dregs, and there will be residue on the surface of the insertion rods 316. When the insertion rods 316 are retracted upward, the bottom end of the horizontal mounting plate 310 can perform a preliminary scraping of the surface of the insertion rods 316, and the fixing rings 323 can perform a secondary scraping of the surface of the insertion rods 316, and the plurality of insertion rods 316 are removed for comprehensive cleaning.

[0030] like Figure 2-5 As shown, when using, it is necessary to stir thoroughly in the early stage of fermentation. Figure 3 and Figure 4As shown, the sixth motor 317 is used to realize synchronous rotation of the two third threaded rods 313, and further realize downward movement of the two top brackets 315. The several insertion rods 316 on the two top brackets 315 move downward along the horizontal mounting plate 310 until the several insertion rods 316 drop to the bottom. At this time, the several insertion rods 316 are inserted into the bottom of the fermentation box 100, and then the third motor 306 drives the second threaded rod 304 to rotate, so as to realize the horizontal movement of the several insertion rods 316, and thoroughly stir the bean dregs in the fermentation box 100; for the gentle turning in the middle stage of fermentation, the fourth motor is first used to drive the mounting block 308 to rotate, so that the several insertion rods 316 are in an inclined state, and then the second telescopic cylinder 309 is used to make the several insertion rods 316 move downward as a whole to the surface of the bean dregs, and then the sixth motor 317 drives the third threaded rod 313 to realize the tilting direction of the several insertion rods 316 Insert it into the surface of the bean dregs, and then slowly move several insertion rods 316 horizontally to flip the surface of the bean dregs. During operation, it is necessary to flip it toward the middle along the edge of the fermentation box 100. The second motor 303 controls the rotation of the mounting bracket 302, so that several insertion rods 316 can be rotated to the edges of the fermentation box 100. The surface bean dregs on the four sides gather toward the middle part. When the surface is flipped and gathered to the middle position, for the sub-surface bean dregs, several insertion rods 316 are also inserted into the sub-surface of the bean dregs in an oblique manner to break the internal lumps, which is conducive to hindering oxygen penetration inside and easily leading to the growth of anaerobic bacteria. The oblique piercing can restore the permeability of the material, accelerate the decomposition of anti-nutritional factors by thermophilic microorganisms, and the oblique angle reduces the physical damage to the active mycelium of protease, thereby maintaining the continuous conversion of protein. Finally, the gathered material in the middle part is backfilled in the same way.

[0031] When in use, the slag turning mechanism 300 can also realize the function of removing part of the material. In the early stage of fermentation, the material is loose and the microorganisms are in a rapid reproduction period. The short-term removal of the surface material and backfilling has little effect on the temperature and oxygen distribution, which can promote the overall material mixing and heat dissipation. Specifically, the surface material is gathered from all sides to the middle position to form a small hill-shaped material, and then the thin plate 312 is placed in a horizontal position, that is, Figure 4In the position shown, the thin plate 312 is horizontally inserted from the bottom of the small hillock, and then the thin plate 312 is controlled to rise to transfer the small hillock to the thin plate 312, and moves horizontally with the thin plate 312. When it moves to the frame 207 on the slag covering component 200, the thin plate 312 is rotated to make the material on it fall into the inside of the frame 207, and then the insertion rod 316 is adjusted to stir the middle and lower bean dregs. After the stirring is completed, the frame 207 is controlled to rise and move horizontally, the carrying plate 208 is pulled out, and several insertion rods 316 are moved to the inside of the frame 207 to stir the material in the frame 207. The bean dregs are stirred and fall downward through the large-aperture screen 209, thereby breaking up and backfilling the agglomerated bean dregs. The bean dregs backfilling in this embodiment is not suitable for the middle and late stages of fermentation, but only for the early stage of fermentation when the bean dregs need to be thoroughly stirred. The slag turning mechanism 300 in this embodiment cooperates with the slag covering assembly 200 to realize the material crushing and backfilling function, and can also be used for loading and spreading other materials in the early stage of fermentation, and then cooperates with a number of insertion rods 316 to realize stirring between different materials.

[0032] At the same time, the slag turning mechanism 300 can also realize the functions of compaction, unloading and side wall cleaning. When in use, the thin plate 312 is rotated to the horizontal position, and the bean dregs in the fermentation box 100 can be compacted by coordinating it to move up and down. After the fermentation is completed, the sealed side panel 102 is opened, the thin plate 312 is rotated to the vertical position, and the insertion rod 316 is moved downward so that its length is greater than the height of the thin plate 312. The thin plate 312 and the insertion rod 316 are coordinated to move horizontally to rake out the material from the sealed side panel 102. This process can be raked out directly using the insertion rod 316, and the final tailings can be raked out using the thin plate 312, or the insertion rod 316 and the thin plate 312 can be used alternately. Different raking methods are used according to the degree of agglomeration of the bean dregs after fermentation. The thin plate 312 is rotated in the opposite direction to point to the side wall of the fermentation box 100, and the material on the side wall of the fermentation box 100 can be scraped off by coordinating it to move up and down.
