Technical Field

[0001] The invention relates to the technical field of soybean protein peptide processing, in particular to a deep processing system for extracting soybean protein peptide. Background Art

[0002] Soy protein peptide is a pure natural nutrient extracted from soybeans and is also an important component of human cells. It is mainly composed of 2-10 amino acids and has a molecular weight of less than 3000. It plays an extremely important role in life activities and has significant medical and health care effects in anti-hypertension, anti-cholesterol, anti-thrombosis, eliminating human fatigue, protecting the liver, preventing arteriosclerosis, enhancing human physical fitness and muscle strength, enhancing human immunity, and treating diabetes. It is a functional health food suitable for both young and old.

[0003] There is also a patent in the prior art about a deep processing system for extracting soybean protein peptides. For example, a Chinese patent with application number CN2008800092186 discloses a centrifugal dryer for separating granular matter from production water. The centrifugal dryer has a housing, a rotor arranged in the housing, and a screen surrounding the rotor on the circumferential side, wherein the screen has at least one porous screen element, which is bent around at least one screen support hoop and can be loosely fixed thereon;

[0004] In the above-mentioned prior art, a housing, a rotor, a screen, a screen element, a screen bracket and a traction member are arranged; the overlapping areas of the above-mentioned prior art nets are butted and flushed with the help of appropriate frame profiles to avoid eddy currents induced in the overlapping areas, thereby fully improving the centrifugal efficiency; however, when the above-mentioned prior art centrifugally dries the soybean protein peptide, the soybean protein peptide liquid has adhesion, and when the soybean protein peptide is thrown out from the centrifugal disk, part of the undried liquid will contact the inner wall of the shell, and the liquid will adhere to the inner wall of the shell, thereby reducing the discharge efficiency of the equipment.

[0005] In view of this, the present invention proposes a deep processing system for extracting soybean protein peptides to solve the above problems. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that when the soy protein peptide is centrifugally dried, the soy protein peptide liquid has stickiness, and when the soy protein peptide is thrown out from the centrifugal disk, part of the undried liquid will contact the inner wall of the shell, and the liquid will stick to the inner wall of the shell, thereby reducing the discharge efficiency of the equipment; the present invention proposes a deep processing system for extracting soy protein peptides.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a deep processing system for extracting soybean protein peptides, the processing system includes an ion exchange unit, a vacuum concentration unit, a high-pressure homogenization unit, a spray drying unit and a screening unit; wherein the spray drying unit includes a centrifugal dryer, and the centrifugal dryer includes a shell and a motor; the shell is provided with a feed inlet and a discharge inlet, and the lower side cross-section of the shell is conical; the motor is fixedly connected to the center position of the upper end of the shell through a bracket, and the output shaft of the motor extends into the shell through the feed inlet; a centrifugal disk is arranged inside the shell, the upper end surface of the centrifugal disk is fixedly connected to the output shaft of the motor, and the inner wall of the shell is fixedly connected to an annular block, the cross-section of the annular block is a right-angled triangle, the right-angled side of the annular block is fixedly connected to the inner wall of the shell, the inclined surface of the annular block faces the centrifugal disk, and the horizontal plane of the annular block is lower than the centrifugal disk; the lower end center position of the centrifugal disk is fixedly connected to a No. 1 shaft, the lower end of the No. 1 shaft is evenly fixedly connected to a No. 1 rod, and the end of the No. 1 rod away from the No. 1 shaft is fixedly connected to a scraper, and the scraper contacts the lower inner wall of the shell;

[0008] When in use, the soybean protein peptide liquid is subjected to centrifugal exchange, the liquid after ion exchange is vacuum concentrated, the liquid after vacuum concentration is subjected to high-pressure homogenization, and then the liquid is spray-dried through an ion dryer, and the soybean protein peptide after spray drying is sieved; when the soybean protein peptide liquid is spray-dried, the motor is started, and the motor rotates, so that the liquid passes through the feed port into the shell, and when the liquid enters the shell, the liquid is poured into the upper end surface of the centrifugal disk from top to bottom, and when the motor rotates, the motor drives the centrifugal disk to rotate, so that after the liquid contacts the centrifugal disk, the liquid is subjected to the centrifugal force generated by the rotation of the centrifugal disk, so that the liquid is evenly thrown out from the outer side of the upper end surface of the centrifugal disk in a mist state, and under the action of the centrifugal force of the centrifugal disk, the liquid is stretched into a thin film on the rotating surface and continuously moves toward the edge, and is atomized when it leaves the edge, and the atomized droplets are thermally heated with the hot air inside the shell The exchange makes the feed liquid dry when it is distributed in a mist form, and part of the feed liquid that is not completely dried contacts the inner wall of the shell, and the feed liquid contacts the annular block along the inner wall of the shell, so that the feed liquid drips along the inclined surface of the annular block to the lower side of the shell. By setting the annular block, the contact area between the feed liquid and the inner wall of the shell is reduced in the process of the feed liquid dripping down on the annular block, thereby reducing the amount of the feed liquid adhering to the inner wall of the shell, so that the feed liquid continues to exchange heat with the hot air during the dripping process, and the incompletely dried feed liquid continues to be dried, thereby improving the discharge efficiency of the centrifugal dryer; and when the motor rotates, the No. 1 shaft at the lower end of the centrifugal disk rotates, and when the No. 1 shaft rotates, the No. 1 shaft drives the No. 1 rod to rotate, and the No. 1 rod drives the scraper to rotate, and the scraper rotates to scrape the inner wall of the lower side of the shell, thereby avoiding the adhesion of the feed liquid to the inner wall of the lower side of the shell, thereby increasing the discharge efficiency of the centrifugal dryer.

[0009] Preferably, a No. 1 groove is provided on the upper end surface of the centrifugal disc, the inner wall of the No. 1 groove is a hemispherical surface, strip blocks are evenly fixed to the inner wall of the No. 1 groove, and the strip blocks are radially arranged with the output shaft of the motor as the center;

[0010] When in use, a No. 1 groove is provided on the upper end surface of the centrifugal disk so that the inner wall of the No. 1 groove is a hemispherical surface, and strip blocks are evenly fixed in the No. 1 groove so that the strip blocks are radially arranged with the output shaft of the motor as the center. When the motor rotates, the motor drives the centrifugal disk to rotate. When the soybean protein peptide liquid enters the shell through the feed inlet, the liquid enters the No. 1 groove. The No. 1 groove accumulates the liquid on the upper end surface of the centrifugal disk, thereby increasing the centrifugal amount of the liquid by the centrifugal disk, and making the mist liquid separated after the liquid is centrifuged more sufficient; when the centrifugal disk rotates, the strip blocks on the inner wall of the No. 1 groove move, so that when the centrifugal disk rotates, the friction between the centrifugal disk and the liquid increases, so that when the liquid is centrifuged by the centrifugal disk, the centrifugal efficiency of the liquid is improved.

[0011] Preferably, an annular groove is provided on the inner wall of the shell, and a second groove is evenly provided below the annular groove, the second groove is located on the inner wall of the shell and is connected to the lower end surface of the annular groove, a slider is slidably connected in the second groove, one end of the slider close to the annular groove extends into the annular groove, a reset spring is sleeved on one side of the slider, a vent is provided on the lower side of the second groove, the vent connects the inside of the shell with the second groove, the outer ring of the centrifugal disk is evenly fixed with a transmission rod, one end of the transmission rod away from the centrifugal disk extends into the annular groove and is slidably connected to the annular groove;

[0012] When in use, after the feed liquid is thrown out from the centrifugal disk by the centrifugal action, the feed liquid follows the annular block, causing the feed liquid to drip downward from the inclined surface on the annular block. When the feed liquid drips, the centrifugal disk rotates, and the transmission rod of the outer ring of the centrifugal disk rotates in the annular groove of the inner wall of the shell. When the transmission rod rotates, the end of the slider close to the annular groove extends out of the No. 2 groove and is located in the annular groove, so that when the transmission rod rotates, the transmission rod squeezes the upper end of the slider, causing the slider to move downward in the No. 2 groove, and the reset spring sleeved on the slider resets the slider. When the slider moves, the slider squeezes the gas in the No. 2 groove, causing the gas in the No. 2 groove to spray out from the vent on the No. 2 groove, and the gas sprayed from the vent blows the dripping feed liquid. On the one hand, the gas accelerates the drying of the feed liquid, and on the other hand, the gas blows the feed liquid to converge to the middle of the shell, thereby reducing the probability of the feed liquid contacting the inner wall of the shell, thereby improving the discharge efficiency of the feed liquid after the soy protein peptide is dried.

[0013] Preferably, the vent hole is in a conical shape, with the end of the vent hole having a smaller aperture being away from the second groove, and the end of the vent hole having a larger aperture being close to the second groove;

[0014] When in use, the vent hole is set in a cone shape, and the end of the vent hole with a small aperture is far away from the second groove, and the end of the vent hole with a large aperture is close to the second groove. When the motor rotates, the motor drives the centrifugal disk to rotate, and the centrifugal disk drives the transmission rod to rotate in the annular groove. The transmission rod squeezes the slider, and the slider squeezes the gas in the second groove, and the gas is ejected from the vent hole. By setting the vent hole in a cone shape, according to the narrow tube effect, the gas pressure and flow rate of the gas are increased when the gas is ejected from the vent hole, thereby further preventing the material liquid from adhering to the inner wall of the shell, thereby improving the discharge efficiency of the centrifugal dryer.

[0015] Preferably, the scraper is arranged on the inner wall of the shell in an inclined downward direction, so that when the scraper rotates, the material moves downward;

[0016] When in use, the scraper is arranged on the inner wall of the shell to be inclined downward. When the motor rotates, the centrifugal disk rotates, the No. 1 shaft at the lower end of the centrifugal disk rotates, the No. 1 shaft drives the No. 1 rod to rotate, and the No. 1 rod drives the scraper to rotate. The scraper is arranged to be inclined downward. When the scraper rotates, the inclined surface of the scraper scraping the inner wall of the shell scrapes the liquid material adhered to the shell, and when the scraper rotates, the scraper forms a tendency to press the liquid material downward, thereby increasing the discharge efficiency of the liquid material after drying.

[0017] Preferably, the strip block is in the shape of an arc;

[0018] When in use, by making the strip block into an arc shape, when the motor moves, the motor drives the centrifugal disk to rotate, and when the centrifugal disk rotates, the strip block on the centrifugal disk rotates with the centrifugal disk. When the feed liquid enters the shell from the feed inlet, the feed liquid contacts the upper end surface of the centrifugal disk. As the centrifugal disk rotates, the feed liquid in contact with the centrifugal disk is subjected to the centrifugal effect, and the feed liquid is dispersed toward the outer ring of the centrifugal disk. By making the strip block into an arc shape, on the one hand, the strip block makes the upper surface of the centrifugal disk uneven, and the friction between the strip block and the centrifugal disk is increased. On the other hand, the strip block is arranged in an arc shape, so that when the strip block rotates with the centrifugal disk, the strip block pushes the feed liquid, and when the feed liquid is thrown out to the outside of the centrifugal disk, the dispersion effect of the feed liquid is increased, thereby improving the drying efficiency of the feed liquid.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The deep processing system for extracting soybean protein peptides described in the present invention is provided with a centrifugal disk, a No. 1 tank, a strip block and a motor; when the motor rotates, the motor drives the centrifugal disk to rotate, and when the soybean protein peptide liquid enters the shell through the feed inlet, the liquid enters the No. 1 tank, and the No. 1 tank causes the liquid to accumulate on the upper end surface of the centrifugal disk, thereby increasing the centrifugal amount of the liquid by the centrifugal disk, so that the mist liquid separated after the liquid is centrifuged is more sufficient; when the centrifugal disk rotates, the strip block on the inner wall of the No. 1 tank moves, so that when the centrifugal disk rotates, the friction between the centrifugal disk and the liquid increases, so that when the liquid is centrifuged by the centrifugal disk, the centrifugal efficiency of the liquid is improved.

[0021] 2. The deep processing system for extracting soybean protein peptides described in the present invention is provided with a shell, an annular groove, a second groove, a slider and a vent; when the slider moves, the slider squeezes the gas in the second groove, so that the gas in the second groove is ejected from the vent on the second groove, and the gas ejected from the vent blows the dripping liquid. On the one hand, the gas accelerates the drying of the liquid, and on the other hand, the gas blows the liquid and makes it converge to the middle of the shell, thereby reducing the probability of the liquid contacting the inner wall of the shell, thereby improving the discharge efficiency of the liquid after the soybean protein peptide is dried.

[0030] When in use, the soybean protein peptide liquid is subjected to centrifugal exchange, the liquid after ion exchange is vacuum concentrated, the liquid after vacuum concentration is subjected to high pressure homogenization, and then the liquid is spray dried by an ion dryer, and the soybean protein peptide after spray drying is sieved; when the soybean protein peptide liquid is spray dried, hot air is introduced into the shell 1, and after the hot air is introduced, the motor 2 is started, and the motor 2 is rotated, so that the liquid is introduced into the shell 1 through the feed inlet 11, and when the liquid enters the shell 1, the liquid is poured from top to bottom into the upper end surface of the centrifugal disk 13, and when the motor 2 is rotated, the motor 2 drives the centrifugal disk 13 to rotate, so that after the liquid contacts the centrifugal disk 13, the liquid is subjected to the centrifugal force generated when the centrifugal disk 13 rotates, so that the liquid is evenly thrown out from the outer side of the upper end surface of the centrifugal disk 13 in the form of mist, and under the action of the centrifugal force of the centrifugal disk 13, the liquid is stretched into a thin film on the rotating surface and continuously moves toward the edge, and is atomized when it leaves the edge, and the atomized droplets are mixed with the hot air inside the shell 1 Heat exchange is performed to dry the feed liquid while it is distributed in a mist form, and part of the feed liquid that is not completely dried contacts the inner wall of the shell 1, and the feed liquid contacts the annular block 14 along the inner wall of the shell 1, so that the feed liquid drips along the inclined surface of the annular block 14 to the lower side of the shell 1. By providing the annular block 14, the contact area between the feed liquid and the inner wall of the shell 1 is reduced during the process of the feed liquid dripping down on the annular block 14, thereby reducing the amount of the feed liquid adhering to the inner wall of the shell 1, so that the feed liquid continues to exchange heat with the hot air during the dripping process. , the incompletely dried liquid continues to be dried, thereby improving the discharge efficiency of the centrifugal dryer; and when the motor 2 rotates, the No. 1 shaft 15 at the lower end of the centrifugal disc 13 rotates, and when the No. 1 shaft 15 rotates, the No. 1 shaft 15 drives the No. 1 rod 151 to rotate, and the No. 1 rod 151 drives the scraper 152 to rotate, and the scraper 152 rotates to scrape the lower inner wall of the shell 1, thereby avoiding the liquid from adhering to the lower inner wall of the shell 1, thereby increasing the discharge efficiency of the centrifugal dryer.

[0031] As a specific embodiment of the present invention, the upper end surface of the centrifugal disc 13 is provided with a No. 1 groove 131, the inner wall of the No. 1 groove 131 is a hemispherical surface, and strip blocks 132 are evenly fixed on the inner wall of the No. 1 groove 131, and the strip blocks 132 are radially arranged with the output shaft of the motor 2 as the center;

[0032] When in use, a groove No. 131 is provided on the upper end surface of the centrifugal disk 13 so that the inner wall of the groove No. 131 is a hemispherical surface, and strip blocks 132 are evenly fixed in the groove No. 131 so that the strip blocks 132 are radially arranged with the output shaft of the motor 2 as the center. When the motor 2 rotates, the motor 2 drives the centrifugal disk 13 to rotate. When the soybean protein peptide liquid enters the interior of the shell 1 through the feed inlet 11, the liquid enters the groove No. 131, and the groove No. 131 causes the liquid to accumulate on the upper end surface of the centrifugal disk 13, thereby increasing the centrifugal amount of the liquid by the centrifugal disk 13, so that the mist-like liquid separated after the liquid is centrifuged is more sufficient; when the centrifugal disk 13 rotates, the strip blocks 132 on the inner wall of the groove No. 131 move, so that when the centrifugal disk 13 rotates, the friction between the centrifugal disk 13 and the liquid increases, so that when the liquid is centrifuged by the centrifugal disk 13, the centrifugal efficiency of the liquid is improved.

[0033] As a specific embodiment of the present invention, an annular groove 16 is provided on the inner wall of the shell 1, and a second groove 17 is evenly provided below the annular groove 16. The second groove 17 is located on the inner wall of the shell 1 and is connected to the lower end surface of the annular groove 16. A slider 18 is slidably connected in the second groove 17. One end of the slider 18 close to the annular groove 16 extends into the annular groove 16. A return spring is sleeved on one side of the slider 18. A vent 19 is provided on the lower side of the second groove 17. The vent 19 connects the interior of the shell 1 with the second groove 17. The outer ring of the centrifugal disk 13 is evenly fixed with a transmission rod 133. One end of the transmission rod 133 away from the centrifugal disk 13 extends into the annular groove 16 and is slidably connected to the annular groove 16.

[0034] When in use, after the feed liquid is thrown out from the centrifugal disk 13 by the centrifugal action, the feed liquid follows the annular block 14, so that the feed liquid drips downward from the inclined surface of the annular block 14. When the feed liquid drips, the centrifugal disk 13 rotates, and the transmission rod 133 of the outer ring of the centrifugal disk 13 rotates in the annular groove 16 on the inner wall of the shell 1. When the transmission rod 133 rotates, the end of the slider 18 close to the annular groove 16 extends out of the second groove 17 and is located in the annular groove 16, so that when the transmission rod 133 rotates, the transmission rod 133 squeezes the upper end of the slider 18, so that the slider 18 is in the second groove 1 7 moves downward, and the reset spring sleeved on the slider 18 resets the slider 18. When the slider 18 moves, the slider 18 squeezes the gas in the second groove 17, so that the gas in the second groove 17 is ejected from the vent 19 on the second groove 17. The gas ejected from the vent 19 blows the dripping liquid. On the one hand, the gas accelerates the drying of the liquid, and on the other hand, the gas blows the liquid and makes it converge to the middle of the shell 1, thereby reducing the probability of the liquid contacting the inner wall of the shell 1, thereby improving the discharge efficiency of the liquid after the soy protein peptide is dried.

[0035] As a specific embodiment of the present invention, the shape of the vent hole 19 is conical, the end of the vent hole 19 with a small aperture is far away from the second groove 17, and the end of the vent hole 19 with a large aperture is close to the second groove 17;

[0036] When in use, the vent hole 19 is set in a conical shape, and the end of the vent hole 19 with a small aperture is far away from the second groove 17, and the end of the vent hole 19 with a large aperture is close to the second groove 17. When the motor 2 rotates, the motor 2 drives the centrifugal disk 13 to rotate, and the centrifugal disk 13 drives the transmission rod 133 to rotate in the annular groove 16. The transmission rod 133 squeezes the slider 18, and the slider 18 squeezes the gas in the second groove 17, and the gas is ejected from the vent hole 19. By setting the vent hole 19 in a conical shape, according to the narrow tube effect, the gas pressure and flow rate of the gas are increased when the gas is ejected from the vent hole 19, thereby further preventing the liquid from adhering to the inner wall of the shell 1, thereby improving the discharge efficiency of the centrifugal dryer.

[0037] As a specific embodiment of the present invention, the scraper 152 is arranged on the inner wall of the housing 1 to be inclined downward, so that when the scraper 152 rotates, the material moves downward;

[0038] When in use, the scraper 152 is set to be inclined downward on the inner wall of the shell 1. When the motor 2 rotates, the centrifugal disc 13 rotates, the No. 1 shaft 15 at the lower end of the centrifugal disc 13 rotates, the No. 1 shaft 15 drives the No. 1 rod 151 to rotate, and the No. 1 rod 151 drives the scraper 152 to rotate. The scraper 152 is set to be inclined downward. When the scraper 152 rotates, the scraper 152 scrapes the inclined surface of the inner wall of the shell 1 against the liquid material adhered to the shell 1, and when the scraper 152 rotates, the scraper 152 forms a downward pressing tendency on the liquid material, thereby increasing the discharge efficiency of the liquid material after drying.

[0039] As a specific embodiment of the present invention, the strip block 132 is in the shape of an arc;

[0040] When in use, by making the strip block 132 into an arc shape, when the motor 2 moves, the motor 2 drives the centrifugal disk 13 to rotate, and when the centrifugal disk 13 rotates, the strip block 132 on the centrifugal disk 13 rotates with the centrifugal disk 13. After the feed liquid is passed into the shell 1 from the feed inlet 11, the feed liquid contacts the upper end surface of the centrifugal disk 13. As the centrifugal disk 13 rotates, the feed liquid in contact with the centrifugal disk 13 is subjected to the centrifugal effect, and the feed liquid is dispersed toward the outer ring of the centrifugal disk 13. By making the strip block 132 into an arc shape, on the one hand, the strip block 132 makes the upper surface of the centrifugal disk 13 uneven, so that the friction force between the feed liquid and the centrifugal disk 13 is increased. On the other hand, the strip block 132 is arranged in an arc shape, so that when the strip block 132 rotates with the centrifugal disk 13, the strip block 132 pushes the feed liquid, and when the feed liquid is thrown out to the outside of the centrifugal disk 13, the dispersion effect of the feed liquid is increased, thereby improving the drying efficiency of the feed liquid.

[0041] The specific workflow is as follows:

[0042] The soy protein peptide liquid is centrifugally exchanged, the liquid after ion exchange is vacuum concentrated, the liquid after vacuum concentration is homogenized under high pressure, and then the liquid is spray dried by an ion dryer, and the soy protein peptide after spray drying is sieved; when the soy protein peptide liquid is spray dried, the motor 2 is started, and the motor 2 is rotated to allow the liquid to pass into the shell 1 through the feed inlet 11. When the liquid enters the shell 1, the liquid is poured from top to bottom into the upper end surface of the centrifugal disk 13. When the motor 2 is rotated, the motor 2 drives the centrifugal disk 13 to rotate. After the liquid contacts the centrifugal disk 13, the liquid is subjected to the centrifugal force generated when the centrifugal disk 13 rotates, so that the liquid is evenly thrown out from the outer side of the upper end surface of the centrifugal disk 13 in the form of mist. Under the action of the centrifugal force of the centrifugal disk 13, the liquid is stretched into a thin film on the rotating surface and continuously moves toward the edge. When it leaves the edge, it is atomized, and the atomized droplets are mixed with the inside of the shell 1 The hot air is heat exchanged to dry the feed liquid when it is distributed in a mist form, and part of the feed liquid that is not completely dried contacts the inner wall of the shell 1, and the feed liquid contacts the annular block 14 along the inner wall of the shell 1, so that the feed liquid drips along the inclined surface of the annular block 14 to the lower side of the shell 1. By setting the annular block 14, the contact area between the feed liquid and the inner wall of the shell 1 is reduced in the process of the feed liquid dripping down on the annular block 14, thereby reducing the amount of the feed liquid adhering to the inner wall of the shell 1, so that the feed liquid continues to exchange heat with the hot air during the dripping process, and the incompletely dried feed liquid continues to be dried, thereby improving the discharge efficiency of the centrifugal dryer; and when the motor 2 rotates, the No. 1 shaft 15 at the lower end of the centrifugal disc 13 rotates, and when the No. 1 shaft 15 rotates, the No. 1 shaft 15 drives the No. 1 rod 151 to rotate, and the No. 1 rod 151 drives the scraper 152 to rotate, and the scraper 152 rotates to scrape the lower inner wall of the shell 1.

The second groove (17) is located on the inner wall of the shell (1) and is connected to the lower end surface of the annular groove (16). A slider (18) is slidably connected in the second groove (17). One end of the slider (18) close to the annular groove (16) extends into the annular groove (16). A return spring is sleeved on one side of the slider (18). A vent (19) is provided on the lower side of the second groove (17). The vent (19) connects the inside of the shell (1) with the second groove (17). The outer ring of the centrifugal disc (13) is evenly fixed with a transmission rod (133). One end of the transmission rod (133) away from the centrifugal disc (13) extends into the annular groove (16) and is slidably connected to the annular groove (16). The ventilation hole (19) is in a conical shape, the end of the ventilation hole (19) with a smaller aperture is far away from the second groove (17), and the end of the ventilation hole (19) with a larger aperture is close to the second groove (17); When in use, after the feed liquid is thrown out from the centrifugal disc (13) by the centrifugal action, the feed liquid flows along the annular block (14) so ​​that the feed liquid drips downward from the inclined surface of the annular block (14). When the feed liquid drips, the centrifugal disc (13) rotates, and the transmission rod (133) on the outer ring of the centrifugal disc (13) rotates in the annular groove (16) on the inner wall of the shell (1). When the transmission rod (133) rotates, one end of the slider (18) close to the annular groove (16) extends out of the second groove (17) and is located in the annular groove (16), so that when the transmission rod (133) rotates, the transmission rod (133) squeezes the upper end of the slider (18), so that the slider (18) The slider (18) moves downward in the second groove (17), and a reset spring sleeved on the slider (18) resets the slider (18). When the slider (18) moves, the slider (18) squeezes the gas in the second groove (17), so that the gas in the second groove (17) is ejected from the vent hole (19) on the second groove (17). The gas ejected from the vent hole (19) blows the dripping liquid. On the one hand, the gas accelerates the drying of the liquid. On the other hand, the gas blows the liquid and makes it converge to the middle of the shell (1), thereby reducing the probability of the liquid contacting the inner wall of the shell (1), thereby improving the discharge efficiency of the liquid after the soy protein peptide is dried.

2. A deep processing system for extracting soybean protein peptides according to claim 1, characterized in that: The scraper (152) is arranged on the inner wall of the shell (1) in an inclined downward direction, so that when the scraper (152) rotates, the material moves downward.

3. A deep processing system for extracting soybean protein peptides according to claim 2, characterized in that: The strip block (132) is in an arc shape.
