Description

Technical Field

[0001] This invention belongs to the field of reaction vessel technology, and specifically relates to a peptide enzymatic hydrolysis reaction vessel for pet food processing. Background Technology

[0002] In the pet food processing process, different feed ingredients need to be mixed after stirring to improve the mixing effect and ensure that the different components of the pet food come into full contact. However, existing pet food processing reactors mostly use a transfer component to drive a single rotating part to rotate, thereby stirring the feed. The stirring range is small, which cannot ensure that the pet food is fully stirred inside the reactor.

[0003] Therefore, it is necessary to invent a peptide enzymatic hydrolysis reactor for pet food processing to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a peptide enzymatic hydrolysis reactor for pet food processing, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a peptide enzymatic hydrolysis reactor for pet food processing, comprising a reactor body, wherein sealing plates are snapped onto the openings at both ends of the reactor body, and an inner circumferential edge is fixed to the inner sidewall of the sealing plate, with the inner sidewall of the circumferential edge correspondingly fitting against the outer circumferential surface of the reactor body; two feed pipes are arranged opposite each other on the top two sides of the reactor body, and a sealing structure is installed at the top opening of each feed pipe; the sealing structure includes a sleeve frame, the bottom end of which is spirally snapped onto the top opening of the feed pipe; the two feed pipes are connected by a connecting pipe. An air extraction pipe is installed at the center of the connecting pipe, and a vacuum pump is connected to the external air extraction pipe. A one-way valve is installed inside the air extraction pipe. Two discharge ports are provided at the bottom of the vessel body, and the two discharge ports correspond one-to-one with two feed pipes. The discharge ports are vertically located at the bottom of the feed pipes. A plug is correspondingly engaged at the bottom of the discharge port to block the discharge port. A rotating rod is provided at the center of the vessel body, penetrating two sealing plates. One end of the rotating rod is connected to a main gear, and the other end of the rotating rod is connected to the output end of a motor. A stirring rack is connected to the surface of the rotating rod and is located inside the vessel body.

[0006] Furthermore, the overall shape of the vessel body is provided with a circular structure, and semi-circular frames are fixed on both sides of the vessel body. Each end of the semi-circular frame is fixed with a locking block. The circumferential edge of the sealing plate is provided with a locking groove corresponding to the locking block. Both sides of the interior of the semi-circular frame are provided with protruding rods that penetrate the locking blocks. The outer end of the protruding rod is connected to a driven gear, and the driven gear meshes with the main gear. The interior of the semi-circular frame is provided with a limiting structure that limits the protruding rods.

[0007] Furthermore, the limiting structure includes a pull plate, with connecting rods that penetrate the semi-circular frame fixed to the inner sides of both ends of the pull plate. A spring is sleeved on the surface of the connecting rod, and the spring is in a compressed state. The outer end of the spring is connected to the inner side of the pull plate, and the inner end of the spring is connected to the outer side of the semi-circular frame. A bracket is fixed to the inner end of the connecting rod, and an annular groove corresponding to the bracket is provided on the surface of the protruding rod.

[0008] Furthermore, the inner end of the protruding rod is configured as a square-round rod, and the limiting structure also includes an internal gear. The internal gear is located at the center inside the semi-annular frame, and the inner wall of the vessel is provided with a groove corresponding to the internal gear. Sleeves are fixed on both sides of the internal gear, and the sleeves are correspondingly sleeved on the surface of the square-round rod at the inner end of the protruding rod, and the inside of the sleeves is configured as a square-round groove.

[0009] Furthermore, a ring frame is provided at the center of the interior of the vessel body. Multiple parallel toothed grooves are arranged in a ring at the center of the outer circumference of the ring frame. The ring frame uses multiple toothed grooves to mesh with the teeth of the internal gear. The outer circumference of the ring frame is in contact with the inner wall of the vessel body, and a stirring rod is fixed to the inner wall of the ring frame. The stirring rod does not contact the stirring frame.

[0010] Furthermore, the width of the ring frame is greater than the width of the slot, and the slot is sealed accordingly by the ring frame.

[0011] Furthermore, the sealing structure also includes an inner tube, the bottom end of which is inserted into the center of the sleeve frame. An elastic element is sleeved on the surface of the inner tube, and a circular plate is connected to the top end of the inner tube. The diameter of the circular plate is larger than the inner diameter of the sleeve frame. The top end of the elastic element is connected to the circular plate, and the bottom end of the elastic element is connected to the top surface of the sleeve frame.

[0012] Furthermore, the inner tube surface is provided with a through-hole, through which the interior of the vessel body is connected to the outside.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. This invention uses a rotating rod to drive the stirring frame to rotate clockwise inside the vessel. The clockwise rotation of the main gear causes the two driven gears to rotate counterclockwise. The counterclockwise rotation of the driven gears, through the convex rod and sleeve, causes the inner gear to rotate counterclockwise inside the semi-ring frame. The counterclockwise rotation of the inner gear drives the ring frame to rotate clockwise inside the vessel. Since the diameter of the main gear is larger than the outer diameter of the ring frame, and the diameters of the inner gear and the driven gears are the same, the linear velocities of the inner gear and the driven gears are the same. Therefore, the rotational speed of the ring frame inside the vessel is greater than the rotational speed of the main gear. The stirring frame and the stirring rod rotate clockwise at different speeds inside the vessel, thus enabling thorough stirring of the pet food inside the vessel.

[0015] 2. In this invention, by pulling the pull plate, the pull plate, through the connecting rod, moves the clamp closer to the inner wall of the semi-annular frame. At this time, the spring is in a stretched state under the pull of the pull plate. After the inner end of the protruding rod is inserted into the inner side of the semi-annular frame, the tension applied to the pull plate is released. The elastic force of the spring causes the pull plate to move closer to the semi-annular frame. The pull plate, through the connecting rod, moves the clamp closer to the protruding rod until the inner end of the clamp is in contact with the surface of the protruding rod. The protruding rod is gradually pushed into the semi-annular frame. The inner end of the clamp slides on the surface of the protruding rod until the inner end of the clamp is locked in the inner side of the annular groove on the surface of the protruding rod. The elastic force of the spring allows the clamp to limit the protruding rod. At this time, the protruding rod uses the gear to limit the sealing plate, which facilitates the sealing plate to seal the opening at the end of the vessel body. The protruding rod can also rotate on the inner side of the clamp using the annular groove.

[0016] 3. In this invention, the circular plate is pressed, and the circular plate cooperates with the sleeve frame to compress the elastic element. Under pressure, the circular plate drives the inner tube to move down inside the sleeve frame until the opening enters the inner side of the sleeve frame. At this time, the circular plate uses the inner tube to seal the sleeve frame. When the vacuum pump draws air from the inside of the vessel through the suction pipe, the air inside the vessel enters the connecting pipe through the feed pipe. The pressure inside the vessel gradually decreases, and the external atmospheric pressure compresses the elastic element through the circular plate. At this time, the sealing structure seals the feed pipe to prevent external air from entering the inside of the vessel through the feed pipe, thus making the inside of the vessel sealed.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] This invention provides a peptide enzymatic hydrolysis reactor for pet food processing, such as... Figures 1 to 3 As shown, the vessel includes a vessel body 1. A heating wire is installed on the inner wall of the vessel body 1, and the heating wire is connected to an external power supply. A sealing plate 2 is snapped into the openings at both ends of the vessel body 1. The inner wall of the sealing plate 2 is fixed with a ring edge, and the inner wall of the ring edge is correspondingly attached to the outer wall of the vessel body 1. Two feed pipes 3 are arranged opposite each other on the top two sides of the vessel body 1. A sealing structure is installed at the top opening of the feed pipe 3. The sealing structure includes a sleeve frame 4. The bottom end of the sleeve frame 4 is screwed into the top opening of the feed pipe 3. The two feed pipes 3 are connected by a connecting pipe 5. A vacuum pipe 6 is installed at the center of the connecting pipe 5. The vacuum pipe 6 is connected to a vacuum pump. A one-way valve is installed inside the vacuum pipe 6. Two discharge ports 7 are provided at the bottom of the vessel body 1. The two discharge ports 7 correspond one-to-one with the two feed pipes 3. The discharge ports 7 are vertically located at the bottom of the feed pipes 3. A plug 8 is snapped into the bottom of the discharge port 7 to seal the discharge port 7. After sealing the outlet 7 with the plug 8, the pet food and peptide enzymes to be processed are fed into the vessel body 1 through the feed pipe 3. The sealing structure is installed inside the feed pipe 3. At this time, the sealing structure seals the feed pipe 3 to prevent outside air from entering the vessel body 1 through the feed pipe 3. The vacuum pump is started. The vacuum pump uses the suction pipe 6 to extract the air inside the connecting pipe 5. At this time, the air inside the vessel body 1 enters the connecting pipe 5 through the feed pipe 3. The vacuum pump gradually evacuates the inside of the vessel body 1.

[0025] A rotating rod 9, penetrating both sealing plates 2, is located at the center of the vessel body 1. One end of the rotating rod 9 is connected to a main gear 10, and the other end is connected to a motor output. A stirring rack 11 is attached to the surface of the rotating rod 9 and is located inside the vessel body 1. The power supply provides energy to the heating wire. When the heating wire heats the pet food inside the vessel body 1, the motor drives the rotating rod 9 to rotate inside the vessel body 1. The rotating rod 9 drives the stirring rack 11 to rotate synchronously inside the vessel body 1, thus stirring the pet food. This stirring and heating method facilitates the enzymatic hydrolysis of the pet food. After treatment, the heating wire continues to heat the pet food inside the vessel body 1 to inactivate the peptidase and bacteria in the pet food. During the heating process of pet food, water vapor is generated. The vacuum pump works continuously, and the water vapor inside the vessel 1 is easily extracted through the one-way valve inside the suction pipe 6 to prevent the water vapor from affecting the production of pet food. After the pet food is processed, the vacuum pump stops working, the plug 8 is removed, and the processed pet food is discharged from the vessel 1 through the discharge port 7, completing the processing of pet food.

[0026] exist Figures 1 to 4 In the process, the overall shape of the vessel body 1 is provided with a ring-shaped structure, and semi-ring frames 12 are fixed on both sides of the vessel body 1. Both ends of the semi-ring frames 12 are fixed with locking blocks 13. The ring edge of the sealing plate 2 is provided with a locking groove 14 corresponding to the locking block 13. The inner sides of the semi-ring frame 12 are provided with protruding rods 15 that penetrate the locking block 13. The outer end of the protruding rod 15 is connected to a driven gear 16, and the driven gear 16 meshes with the main gear 10. The inner side of the semi-ring frame 12 is provided with a limiting structure that limits the protruding rod 15. After aligning the ring edge of the sealing plate 2 with the opening at the end of the vessel body 1, the groove 14 of the ring edge and the locking block 13 at the end of the semi-ring frame 12 are engaged. The sealing plate 2 is then locked onto the end of the vessel body 1. The inner end of the protruding rod 15 passes through the sealing plate 2 and the locking block 13. After the inner end of the protruding rod 15 is constrained by the limiting structure, the driven gear 16 at the outer end of the protruding rod 15 meshes with the main gear 10. When the motor works and the rotating rod 9 rotates, the rotating rod 9 drives the stirring rack 11 to rotate inside the vessel body 1. At the same time, the rotating rod 9 drives the driven gear 16 to rotate using the main gear 10. The driven gear 16 causes the protruding rod 15 to rotate inside the semi-ring frame 12.

[0027] exist Figure 3 and Figure 4 In the above, the limiting structure includes a pull plate 17, with connecting rods fixed to the inner sides of both ends of the pull plate 17, penetrating the semi-annular frame 12. A spring 18 is sleeved on the surface of the connecting rod, and the spring 18 is in a compressed state. The outer end of the spring 18 is connected to the inner side of the pull plate 17, and the inner end of the spring 18 is connected to the outer side of the semi-annular frame 12. A bracket 19 is fixed to the inner end of the connecting rod. The surface of the protruding rod 15 is provided with an annular groove 20 corresponding to the bracket 19. Pulling the pull plate 17 causes the connecting rod to move the bracket 19 closer to the inner wall of the semi-annular frame 12. At this time, the spring 18 is in a stretched state under the pull of the pull plate 17. After the inner end of the protruding rod 15 is inserted into the inner side of the semi-annular frame 12, the tension applied to the pull plate 17 is released. The elastic force of the spring 18 causes the pull plate 17 to move closer to the semi-annular frame 12. The pull plate 17, through the connecting rod, moves the bracket 19 closer to the protruding rod 15 until the inner end of the bracket 19 is in contact with the protruding rod 15. On the surface of the protruding rod 15, the protruding rod 15 is gradually pushed into the semi-annular frame 12. The inner end of the bracket 19 slides on the surface of the protruding rod 15 until the inner end of the bracket 19 is correspondingly snapped into the inner side of the annular groove 20 on the surface of the protruding rod 15. The elastic force of the spring 18 allows the bracket 19 to limit the protruding rod 15. At this time, the protruding rod 15 uses the gear 16 to limit the sealing plate 2, which makes it convenient for the sealing plate 2 to seal the opening at the end of the vessel body 1. The protruding rod 15 can also rotate on the inner end of the bracket 19 using the annular groove 20.

[0028] exist Figure 3 and Figure 4In the process, the inner end of the protruding rod 15 is set as a square-round rod. The limiting structure also includes an internal gear 21. The internal gear 21 has the same diameter as the driven gear 16. The internal gear 21 is located at the center inside the semi-annular frame 12, and the inner wall of the vessel body 1 is provided with a groove corresponding to the internal gear 21. Both sides of the internal gear 21 are fixed with sleeves 22. The sleeves 22 are correspondingly sleeved on the surface of the square-round rod at the inner end of the protruding rod 15, and the inside of the sleeves 22 is set as a square-round groove. After the inner end of the protruding rod 15 enters the inner side of the semi-annular frame 12, the inner end of the spring clip 19 of the spring 18 is attached to the surface of the protruding rod 15. The square and round rod of the inner end of the protruding rod 15 enters the sleeve 22 until the inner end of the clip 19 is engaged with the annular groove 20. At this time, the protruding rod 15 is inserted into the square and round groove of the sleeve 22 by the square and round rod. When the main gear 10 drives the protruding rod 15 to rotate by the driven gear 16, the square and round rod of the inner end of the protruding rod 15 drives the internal gear 21 to rotate inside the semi-annular frame 12 by the sleeve 22.

[0029] A ring frame 23 is provided at the center of the interior of the vessel body 1. Multiple parallel toothed grooves are arranged in a ring around the center of the outer circumference of the ring frame 23. These grooves mesh with the teeth of the internal gear 21. The outer circumference of the ring frame 23 is in contact with the inner wall of the vessel body 1, and a stirring rod 24 is fixed to the inner wall of the ring frame 23. The stirring rod 24 does not contact the stirring frame 11. The width of the ring frame 23 is greater than the width of the groove opening, thus sealing the groove opening. The rotating internal gear 21 drives the ring frame 23 to rotate inside the vessel body 1. The rotating ring frame 23 seals the groove opening, preventing pet food from entering the inner side of the semi-ring frame 12. The protruding rod 15 seals the end of the semi-ring frame 12, and the ring frame 23 seals the groove opening, preventing outside air from entering the interior of the vessel body 1 through the semi-ring frame 12, ensuring a vacuum effect inside the vessel body 1.

[0030] When the ring frame 23 rotates under the drive of the internal gear 21, the ring frame 23 drives the stirring rod 24 to rotate synchronously inside the vessel body 1. When the motor operates, the rotating rod 9 causes the main gear 10 to rotate clockwise, which in turn causes the stirring frame 11 to rotate clockwise inside the vessel body 1. The clockwise rotation of the main gear 10 causes the two driven gears 16 to rotate counterclockwise. The counterclockwise rotation of the driven gears 16, through the convex rod 15 and the sleeve 22, causes the internal gear 21 to rotate counterclockwise inside the semi-ring frame 12. The counterclockwise rotation of the internal gears... Wheel 21 drives ring frame 23 to rotate clockwise inside the vessel 1. Since the diameter of main gear 10 is larger than the outer diameter of ring frame 23, and the diameters of internal gear 21 and driven gear 16 are the same, the linear velocities of internal gear 21 and driven gear 16 are the same. Therefore, the rotational speed of ring frame 23 inside the vessel 1 is greater than the rotational speed of main gear 10. At this time, the speeds of stirring frame 11 and stirring rod 24 rotating clockwise inside the vessel 1 are different, thus enabling the pet food inside the vessel 1 to be fully stirred.

[0031] exist Figure 1 and Figure 5 The sealing structure further includes an inner tube 25, the bottom end of which is inserted into the center of the sleeve frame 4. An elastic element 26 is fitted onto the surface of the inner tube 25, and a circular plate is connected to the top of the inner tube 25. The diameter of the circular plate is larger than the inner diameter of the sleeve frame 4. The top of the elastic element 26 is connected to the circular plate, and the bottom end of the elastic element 26 is connected to the top surface of the sleeve frame 4. An opening 27 is provided on the surface of the inner tube 25, and the inside of the vessel body 1 is connected to the outside through the opening 27 on the surface of the inner tube 25. After the pet food and peptide enzyme enter the inside of the vessel body 1 through the feed pipe 3, the bottom end of the sleeve frame 4 is screwed and fastened to the opening of the feed pipe 3. At this time, the elastic force of the elastic element 26, using the circular plate, prevents the inner tube 25 from completely entering the inside of the sleeve frame 4, that is, the opening 27 on the surface of the inner tube 25 is at the top of the sleeve frame 4. Pressing the circular plate causes it to cooperate with the sleeve frame 4 to compress the elastic element 26. Under pressure, the circular plate drives the inner tube 25 to move down inside the sleeve frame 4 until the opening 27 enters the inside of the sleeve frame 4. At this time, the circular plate uses the inner tube 25 to seal the sleeve frame 4. When the vacuum pump draws air from the inside of the vessel body 1 through the suction pipe 6, the air inside the vessel body 1 enters the connecting pipe 5 through the feed pipe 3. The pressure inside the vessel body 1 gradually decreases. The external atmospheric pressure compresses the elastic element 26 through the circular plate. At this time, the sealing structure seals the feed pipe 3 to prevent external air from entering the inside of the vessel body 1 through the feed pipe 3, thus making the inside of the vessel body 1 sealed.

[0032] After the vacuum pump stops working, the circular plate is pulled up, and the circular plate drives the inner tube 25 to move up inside the sleeve 4 until the port 27 moves out of the sleeve 4. Then, outside air enters the inside of the vessel 1 through the port 27 until the air pressure inside the vessel 1 is the same as outside. Then, the plug 8 is separated from the discharge port 7, so that the processed pet food inside the vessel 1 can be discharged through the discharge port 7.

[0033] Working principle of this invention:

[0034] Reference Figures 1 to 5 As shown, after aligning the ring edge of the sealing plate 2 with the opening at the end of the vessel body 1, the slot 14 of the ring edge and the locking block 13 at the end of the semi-ring frame 12 will cooperate accordingly. At this time, the sealing plate 2 will be locked at the end of the vessel body 1, and the inner end of the protruding rod 15 will pass through the sealing plate 2 and the locking block 13.

[0035] Pulling the pull plate 17 causes the connecting rod to move the bracket 19 closer to the inner wall of the semi-ring frame 12. At this time, the spring 18 is in a stretched state under the pull of the pull plate 17. After the inner end of the protruding rod 15 is inserted into the inner side of the semi-ring frame 12, the tension applied to the pull plate 17 is released. The elastic force of the spring 18 causes the pull plate 17 to move closer to the semi-ring frame 12. The pull plate 17, through the connecting rod, moves the bracket 19 closer to the protruding rod 15 until the inner end of the bracket 19 is in contact with the surface of the protruding rod 15. After the inner end of the protruding rod 15 enters the inner side of the semi-ring frame 12, the pull plate 17 moves the bracket 19 closer to the protruding rod 15. At this time, the inner end of the spring clip 19 of the spring 18 is attached to the surface of the protruding rod 15, and the square and round rod of the inner end of the protruding rod 15 enters the sleeve 22 until the inner end of the clip 19 is engaged with the annular groove 20. At this time, the protruding rod 15 is inserted into the square and round groove of the sleeve 22 by the square and round rod. When the main gear 10 drives the protruding rod 15 to rotate by the driven gear 16, the square and round rod of the inner end of the protruding rod 15 drives the internal gear 21 to rotate inside the semi-annular frame 12 by the sleeve 22, and the protruding rod 15 can also rotate inside the clip 19 by the annular groove 20.

[0036] Since the diameter of the main gear 10 is larger than the outer diameter of the ring frame 23, and the diameters of the internal gear 21 and the driven gear 16 are the same, the linear velocities of the internal gear 21 and the driven gear 16 are the same. Therefore, the rotational speed of the ring frame 23 inside the vessel 1 is greater than the rotational speed of the main gear 10. At this time, the rotational speeds of the stirring rack 11 and the stirring rod 24 inside the vessel 1 are different, which enables the pet food inside the vessel 1 to be fully stirred.

[0037] After the outlet 7 is blocked by the plug 8, the pet food and peptide enzymes to be processed are introduced into the vessel body 1 through the feed pipe 3. The circular plate is pressed, and the circular plate and the sleeve frame 4 cooperate to squeeze the elastic element 26. Under the pressure, the circular plate drives the inner tube 25 to move down inside the sleeve frame 4 until the outlet 27 enters the inside of the sleeve frame 4. At this time, the circular plate uses the inner tube 25 to block the sleeve frame 4. When the vacuum pump draws air from the inside of the vessel body 1 through the air extraction pipe 6, the air inside the vessel body 1 enters the connecting pipe 5 through the feed pipe 3. The pressure inside the vessel body 1 gradually decreases. The external atmospheric pressure squeezes the elastic element 26 through the circular plate. At this time, the sealing structure blocks the feed pipe 3 to prevent external air from entering the inside of the vessel body 1 through the feed pipe 3, so that the inside of the vessel body 1 is sealed.

[0038] The power supply provides electrical energy to the heating wire. When the heating wire heats the pet food inside the vessel 1, the motor drives the rotating rod 9 to rotate inside the vessel 1. The rotating rod 9 drives the stirring rack 11 to rotate synchronously inside the vessel 1. The rotating stirring rack 11 is used to stir the pet food. The stirring and heating method facilitates the enzymatic hydrolysis of the pet food. After the treatment, the heating wire continues to heat the pet food inside the vessel 1 to inactivate the peptidase and bacteria in the pet food. During the heating process of pet food, water vapor is generated. The vacuum pump works continuously, and the water vapor inside the vessel 1 is easily extracted through the one-way valve inside the suction pipe 6 to prevent water vapor from affecting the production of pet food. After the pet food is processed, the vacuum pump stops working, and the circular plate is pulled up. The circular plate drives the inner tube 25 to move up inside the sleeve 4 until the outlet 27 moves out of the sleeve 4. Then, outside air enters the inside of the vessel 1 through the outlet 27 until the air pressure inside the vessel 1 is the same as outside. Then, the plug 8 is separated from the discharge port 7 to facilitate the discharge of the processed pet food inside the vessel 1 through the discharge port 7.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
