Description

Technical Field

[0001] This utility model belongs to the field of soybean polypeptide processing technology, and more specifically, it relates to an environmentally friendly enzymatic hydrolysis device for soybean protein. Background Technology

[0002] In recent decades, scientists have discovered that enzymatic hydrolysis of proteins in various natural foods can generate peptides with smaller molecular weights. These peptides not only provide the body with abundant nutrition, but some also have various health benefits and can improve human health. They have been widely used and developed in the food, health product, and pharmaceutical industries. The current protein peptide industry has formed a complete series of protein peptide processes, including protein raw material pretreatment, enzymatic hydrolysis, enzyme inactivation, centrifugation, membrane filtration, decolorization, concentration, and spray drying. Various devices for processing soybean protein have appeared on the market.

[0003] Chinese patent with authorization announcement number "CN218491760U" discloses a soybean polypeptide enzymatic hydrolysis device, including a reaction vessel body. A motor is installed at the bottom of the reaction vessel body, and the motor is connected to a rotating rod. A stirring blade is fixedly connected to the side wall of the rotating rod. A filter element is sleeved on the side wall of the rotating rod, and a sealing element is sleeved on the outside of the filter element. The sealing element can slide up and down on the filter element. This device can fully mix soybean protein slurry and enzymatic hydrolysate to ensure enzymatic hydrolysis efficiency. After enzymatic hydrolysis, the polypeptide solution and solid matter can be discharged separately to facilitate subsequent processing of the polypeptide solution.

[0004] During later use, the device also exhibited the following problems: 1. When enzymatically hydrolyzing soybean slurry, the filter screen is prone to corrosion due to prolonged immersion in the pH level, which requires specific pH levels; 2. Moving the annular cover upwards to detach it from the support plate fails to completely remove the solid matter, affecting subsequent processing of the soybean slurry; 3. Centrifugation is ineffective in separating peptide solutions, resulting in a high peptide content in the solid matter, which reduces peptide yield and hinders subsequent reprocessing and recycling of the solid matter.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By changing the filtration mechanism from centrifugal filtration to extrusion filtration, the separation of polypeptide liquid and solid impurities can be more complete, which facilitates the subsequent environmentally friendly recycling of solid impurities. At the same time, the filter screen is fixed by the latches. When the filter screen moves to the cavity area under the push of the push rod assembly, the staff can complete the disassembly and replacement of the filter screen by lifting the latches.

[0015] 3. By designing a stirring mechanism, the stirring rod applies shear force to the mixture of enzymatic hydrolysate and soybean protein solution to promote mixing. The propeller blades, in conjunction with the sleeve, allow the mixture to flow axially, promoting circulation within the mixing tank and avoiding dead zones that could affect the stirring effect.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an environmentally friendly enzymatic hydrolysis device for soybean protein includes a mounting base 3, with support legs 301 fixedly connected to the bottom of the mounting base 3. Figure 8 As shown, a squeezing chamber 305 is fixedly opened on the left side inside the mounting base 3. A filter mechanism 4 is installed inside the squeezing chamber 305. By changing the filter mechanism 4 from centrifugal filtration to squeezing filtration, the peptide liquid can be separated from solid impurities more completely, which is convenient for subsequent environmentally friendly recycling of solid impurities. At the same time, the filter screen 404 is fixed by the latch 403. When the filter screen 404 moves to the cavity 306 area under the push of the push rod assembly 401, the operator can complete the disassembly and replacement of the filter screen 404 by lifting the latch 403. When the filter screen 404 moves to the squeezing chamber 305 area under the pull of the push rod assembly 401, the inner wall of the squeezing chamber 305 squeezes the latch 403 to lock the latch 403, ensuring that the filter screen 404 is firmly fixed on the squeezing pusher 402.

[0034] A feed port 304 is fixedly provided on the top left side of the extrusion chamber 305. The top of the feed port 304 is connected to the feed pipe 105. The mixture after being stirred in the mixing tank 1 flows into the extrusion chamber 305 through the feed pipe 105 and the feed port 304 for extrusion filtration. A liquid outlet valve pipe 302 is fixedly connected to the bottom left side of the extrusion chamber 305. The filtered polypeptide liquid is discharged from the liquid outlet valve pipe 302. A cavity 306 is fixedly provided on the right side inside the mounting base 3. The inner diameter of the cavity 306 is larger than the inner diameter of the extrusion chamber 305. A limiting component 5 is provided in the cavity 306. By setting the limiting component 5, when the limiting plate 501 is fixed, it can be matched with the filter screen 404. The process involves filtering and separating the polypeptide solution and fixed impurities. When the limiting disk 501 moves freely, it moves to the right and rotates under the push of the filter screen 404. The protrusion 501A scrapes and cleans the impurities on the surface of the filter screen 404. A slot 306A is fixedly opened on the inner wall of the left side of the cavity 306. The inner diameter of the slot 306A is larger than the inner diameter of the cavity 306. When the locking block 502 is inserted into the slot 306A, the position of the limiting disk 501 is fixed. When the pressing block 503 is pushed by the filter screen 404, the locking block 502 is squeezed downward by the pressing block 503 and disengages from the slot 306A, allowing the limiting disk 501 to slide freely in the cavity 306.

[0035] A slag discharge port 303 is fixedly opened at the bottom of the cavity 306. The solid impurities after filtration are discharged from the slag discharge port 303. A spiral rotating hole 307 is opened on the right side wall of the mounting base 3. The spiral rotating hole 307 is provided with a spiral groove, and the stud 504 is provided with a thread. The spiral groove and the thread engage. When the stud 504 moves backward, it is limited by the spiral groove, which causes the stud 504 to rotate, thereby driving the limiting disk 501 to rotate, thus scraping the filter screen 404. A rear tank 308 is fixedly connected to the right side of the mounting base 3, and a mixing tank 1 is fixedly connected to the top of the mounting base 3. The mixing tank 1 is provided with a stirring mechanism 2. By designing the stirring mechanism 2, the stirring rod 202C applies shear force to the mixture of enzymatic hydrolysate and soybean protein liquid to promote its mixing. The propeller blade 202A and the sleeve 202B make the mixture flow axially, promote the circulation of the mixture in the mixing tank 1, avoid the formation of mixing dead zones, and avoid affecting the stirring effect.

[0036] like Figure 4 As shown, a jacket 101 is fixedly provided on the side wall of the mixing tank 1. A water outlet 103 extends outward from the upper part of the jacket 101, and a water inlet 104 extends outward from the lower part of the jacket 101. A feed inlet 102 is fixedly provided on the top of the mixing tank 1, and a feed pipe 105 is fixedly connected to the center of the bottom of the mixing tank 1. An inner cylinder 105A is fixedly connected to the center of the feed pipe 105. A through-hole 105B is fixedly provided on the inner cylinder 105A, and a slot 105C is fixedly provided on the side wall of the through-hole 105B. The enzymatic hydrolysate and soybean protein solution are poured into the mixing tank 1 through the feed inlet 102. Warm water flows into the jacket 101 through the water inlet 104 and is discharged from the water outlet 103, thereby achieving temperature control inside the mixing tank 1 and keeping the enzymatic hydrolysis reaction in the most suitable temperature range. The hydrolyzed mixture flows downward into the extrusion chamber 305 through the through-hole 105B.

[0037] like Figure 5 , Figure 6 and Figure 7As shown, the stirring mechanism 2 includes a drive motor 201, which is fixedly connected to the top of the mixing tank 1. The output shaft of the drive motor 201 is fixedly connected to an agitator 202, which includes a propeller blade 202A. A sleeve 202B is fixedly connected to the outside of the propeller blade 202A. Multiple sets of stirring rods 202C are fixedly connected to the outer wall of the sleeve 202B. A feeding screw 203 is fixedly connected to the bottom of the agitator 202. A rotary valve 204 is rotatably connected to the bottom of the feeding screw 203. A ball groove 203A is fixedly opened on the outer wall of the bottom of the feeding screw 203. The rotary valve 204 includes a rotating seat 204A, whose outer wall is rotatably connected to the inner cylinder 105A. A valve plate 204B is fixedly connected to the top of the rotating seat 204A. The valve plate 204B cooperates with the port 105B. When the valve plate 204B... After rotation, the opening 105B is blocked, which prevents the connection between the mixing tank 1 and the extrusion chamber 305. A stop block is fixedly connected to the valve plate 204B. A slot 204D is fixedly opened in the rotating seat 204A. A compression spring 204F is fixedly connected to the bottom of the slot 204D. A sliding rod 204E is fixedly connected to the other end of the compression spring 204F. Under the push of the compression spring 204F, the sliding rod 204E extends out of the slot 204D and gets into the ball groove 203A, providing rotational resistance for the rotational contact between the rotary valve 204 and the feeding screw 203. This allows the rotation of the feeding screw 203 to drive the rotation of the rotary valve 204. However, after the rotary valve 204 rotates to the limit position, the resistance from the feeding pipe 105 is much greater than the torque brought by the feeding screw 203. At this time, the rotary valve 204 stops rotating with the feeding screw 203.

[0038] The slide rod 204E is slidably connected to the slot 204D, and the slide rod 204E contacts the ball groove 203A under the push of the compression spring 204F. The drive motor 201 drives the agitator 202 and the feed screw 203 to rotate in the forward direction. At this time, the mixed liquid is stirred in the mixing tank 1. The rotary valve 204 rotates in the forward direction under the drive of the feed screw 203 until the stop block 204C contacts the side wall of the port 105B. At this time, the valve plate 204B completely blocks the port 105B, the rotary valve 204 closes, and the mixed liquid remains in the mixing tank 1 for stirring and enzymatic hydrolysis. The drive motor 201 drives the agitator 202 and the feed screw 203 to rotate in the reverse direction. At this time, the rotary valve 204 rotates in the reverse direction under the drive of the feed screw 203 until the stop block 204C contacts the slot 105C. At this time, the valve plate 204B avoids the port 105B, the port 105B opens, and the reverse rotation of the feed screw 203 can push the mixed liquid to flow downward, so that the mixed liquid passes through the port 105B and flows from the mixing tank 1 into the extrusion chamber 305.

[0039] like Figure 9 and Figure 10As shown, the filter mechanism 4 includes a push rod assembly 401, which is fixedly connected to the left side wall of the mounting base 3. A compression pusher 402 is fixedly connected to the push rod end of the push rod assembly 401. The outer wall of the compression pusher 402 slides in contact with the compression chamber 305. Multiple sets of claw grooves 402A are fixedly formed on the outer wall of the compression pusher 402. Claws 403 are rotatably connected to the claw grooves 402A. A torsion spring is also fixedly connected to the groove, and the other end of the torsion spring is fixedly connected to the claw 403. Under the elastic force of the torsion spring, the claw 403 maintains an inward clamping tendency, ensuring... The filter screen 404 is fixed on the extrusion pusher 402. When the filter screen 404 needs to be removed, the operator lifts the latch 403 to remove the filter screen 404, places the cleaned new filter screen 404 on the extrusion pusher 402, aligns the latch groove 404A with the claw groove 402A, and releases the latch 403 to fix the filter screen 404. The filter screen 404 is located on the right side of the extrusion pusher 402. Multiple sets of latch grooves 404A are fixedly opened on the outer wall of the filter screen 404, and the latch grooves 404A cooperate with the latch 403. The pusher assembly 401 extends the pusher to drive the filter screen 404 to move towards the limiting plate 501, continuously extruding and filtering the mixed liquid. The polypeptide liquid passes through the filter screen 404 and exits from the liquid outlet valve pipe 302 on the left side of the extrusion chamber 305.

[0040] like Figure 11 and Figure 12 As shown, the limiting component 5 includes a limiting disk 501. The outer wall of the limiting disk 501 slides in contact with the cavity 306. A protrusion 501A is fixedly connected to the left side wall of the limiting disk 501. By setting the protrusion 501A, when the limiting disk 501 contacts the filter screen 404 and rotates relative to it, the protrusion 501A scrapes and cleans the fixed impurities on the surface of the filter screen 404. Multiple sets of vertical slides 501B are radially opened inside the limiting disk 501. A horizontal slide 501C is fixedly opened on the vertical slide 501B. A limiting groove 501D is fixedly opened on the inner wall of the horizontal slide 501C. A stud 504 is fixedly connected to the right side wall of the limiting disk 501. A compression spring 505 is fixedly connected to the right side of the stud 504. The other end of the compression spring 505 rotates in contact with the inner wall of the rear tank 308. When the limiting disc 501 is pushed to the right by the filter screen 404, the limiting disc 501 rotates under the limiting action of the stud 504 and the spiral rotating hole 307, so as to scrape and clean the filter screen 404.

[0041] like Figure 13 and Figure 14As shown, a locking block 502 is slidably connected to the vertical slide rail 501B. A pressing slide opening 502B is fixedly opened in the middle of the locking block 502. A second compression spring 502A is fixedly connected to the bottom of the locking block 502. The other end of the second compression spring 502A is fixedly connected to the bottom of the vertical slide rail 501B. A pressure block 503 is slidably connected to the horizontal slide rail 501C. A protruding plate 503A is fixedly connected to both sides of the pressure block 503. A third compression spring 503B is fixedly connected to the right side of the protruding plate 503A. The other end of the third compression spring 503B is fixedly connected to the inner wall of the limiting slide groove 501D. When the pressure block 503 slides to the right, it contacts the pressing slide opening 502B and causes the locking block 502 to retract into the vertical slide rail 501B. The locking block 502 extends outward from the vertical slide 501B under the push of the second compression spring 502A and can be locked into the locking groove 306A. The pressing block 503 extends out from the horizontal slide 501C under the push of the third compression spring 503B. The right side of the pressing block 503 cooperates with the extrusion slide 502B.

[0042] Work process:

[0043] 1. Soybean slurry and enzymatic hydrolysate are introduced into mixing tank 1 through inlet 102. Warm water with controlled temperature is introduced through inlet 104 and flows out through outlet 103. Drive motor 201 is started and controlled to rotate in the forward direction. At this time, stirring component 202 stirs and mixes the liquid in the tank. At the same time, feeding screw 203 drives rotary valve 204 to rotate, so that rotary valve 204 is closed.

[0044] 2. After the soybean slurry is enzymatically hydrolyzed, the drive motor 201 is controlled to rotate in reverse. At this time, the rotary valve 204 is opened, and the feeding screw 203 pushes the mixture downward. The mixture flows from the mixing tank 1 into the extrusion chamber 305.

[0045] 3. The push rod assembly 401 pushes the extrusion pusher 402, and the filter screen 404 and the limiting plate 501 move closer and closer to each other, extruding and filtering the mixture, and the polypeptide liquid is discharged from the outlet valve pipe 302.

[0046] 4. When the distance between the filter screen 404 and the limiting plate 501 approaches the limit position, the filter screen 404 begins to contact and squeeze the pressure block 503. The pressure block 503 pushes the squeezing slide 502B of the locking block 502 backward, causing the locking block 502 to retract and disengage from the locking groove 306A. The limiting plate 501 is released from the fixed state, the push rod assembly 401 continues to extend, the filter screen 404 enters the cavity 306 area and continues to push the limiting plate 501. The limiting plate 501 rotates while moving backward, scraping and cleaning the fixed impurities on the filter screen 404. The fixed impurities are discharged from the slag discharge port 303.

[0047] 5. When the filter screen 404 needs to be replaced, the operator opens the latch 403 that extends into the cavity 306 through the slag discharge port 303, and the filter screen 404 can be replaced. After the filter screen 404 is replaced, it returns to the area of ​​the extrusion chamber 305 along with the push rod assembly 401. Under the extrusion limit of the inner wall of the extrusion chamber 305, the latch 403 is firmly pressed into the latch groove 404A, thereby locking the latch 403.

[0048] This invention, by setting a limiting component 5, when the limiting disk 501 is fixed, can cooperate with the filter screen 404 to complete the filtration and separation of polypeptide liquid and fixed impurities. When the limiting disk 501 moves freely, it moves to the right and rotates under the push of the filter screen 404, and the convex strip 501A scrapes and cleans the impurities on the surface of the filter screen 404. By designing a stirring mechanism 2, the stirring rod 202C applies shear force to the mixture of enzymatic hydrolysate and soybean protein liquid to promote its mixing. The propeller blade 202A, in conjunction with the sleeve 202B, causes the mixture to flow axially, promoting the circulation of the mixture in the mixing tank 1 and avoiding the formation of mixing dead zones, which would affect the stirring effect.
