Description

Technical Field

[0001] This invention relates to the field of enzymatic hydrolysis equipment technology, and more specifically, to an enzymatic hydrolysis reaction device for pet food. Background Technology

[0002] Enzymatic hydrolysis is essentially a biocatalytic process that uses enzymes (a type of protein biocatalyst) to efficiently break down large molecules into smaller molecules under mild conditions.

[0003] For some young, old, or sick pets with weak digestive abilities, large molecules such as chicken, liver, and corn are difficult to absorb quickly and can even easily cause diarrhea. Therefore, it is usually necessary to perform enzymatic hydrolysis on the food to break down large protein molecules into small peptides and amino acids, starch into small sugar molecules, and fat into glycerol and fatty acids. These small molecules can be directly absorbed by the intestines without much digestion, greatly reducing the digestive burden. In addition, the enzymatic hydrolysis process releases a large number of flavor amino acids (such as glutamic acid and aspartic acid) and small peptide molecules, producing a rich meaty aroma and umami flavor, which can greatly stimulate the pet's appetite.

[0004] Existing enzymatic hydrolysis equipment for pet food, such as the Chinese utility model patent CN221566173U (an enzymatic hydrolysis equipment for pet flavoring agents), mostly involves first pouring the food raw materials into a reaction vessel, then heating the raw materials to a suitable temperature before directly adding all the enzyme preparation. However, adding a large amount of enzyme at once may lead to partial inactivation under the initial high-temperature environment, resulting in a decrease in overall efficiency. Furthermore, excessively high enzyme concentrations in the initial stage of the reaction can cause overly vigorous hydrolysis, producing too many small molecule peptides or bitter peptides, affecting the product's flavor. Later, decreased enzyme activity and hydrolysis efficiency result in a wide and uneven molecular weight distribution of the final product, severely impacting the hydrolysis effect. Although some patents have improved this by adding enzyme preparations in stages, this requires pausing the reaction before adding the enzyme, significantly affecting the hydrolysis efficiency. Additionally, external oxygen can easily enter the reaction vessel during enzyme addition, potentially disrupting the hydrolysis environment and further reducing the hydrolysis effect. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide an enzymatic hydrolysis reaction device for pet food, which can improve the effect of the enzymatic hydrolysis reaction.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A pet food enzymatic hydrolysis reaction device includes a reaction vessel, a motor is fixedly installed on the top wall of the reaction vessel, a reciprocating lead screw is fixedly installed on the output end of the motor, a rotating rod is fixedly installed on the bottom end of the reciprocating lead screw, a stirring rod is uniformly fixedly installed on the rotating rod, and a feeding assembly is provided on the reaction vessel; The feeding assembly includes a feeding block fixedly installed on the top plate inside the reaction vessel. The feeding block has a storage trough. The top wall of the reaction vessel has an addition trough. A sealing plug is detachably installed in the addition trough. The rotating rod has a vertical groove. The stirring rod has a horizontal groove communicating with the vertical groove. The horizontal groove has feeding holes evenly distributed. The vertical groove has a feeding port communicating with the storage trough. The feeding block has a linkage assembly that cooperates with the feeding port.

[0008] Furthermore, the linkage component includes an annular groove formed on the feeding block, a sealing ring slidably installed in the annular groove, a first spring jointly installed between the sealing ring and the annular groove, a linkage block threaded on the reciprocating screw, a telescopic rod fixedly installed between the top of the linkage block and the reaction vessel, a vertical rod fixedly installed at the top of the sealing ring, a feed inlet opened on the side wall of the reaction vessel, a stopper plate detachably installed in the feed inlet, and a discharge valve fixedly installed on the bottom wall of the reaction vessel.

[0009] Furthermore, hollow rods are uniformly fixedly installed inside the storage tank, and elastic rods are fixedly installed on the hollow rods. The feeding block has a round hole that mates with the elastic rod, and a shaking groove is provided on the hollow rod. The bottom end of the elastic rod extends into the shaking groove.

[0010] Furthermore, a horizontal plate is slidably installed in the vibration groove, and a second spring is installed between the horizontal plate and the vibration groove. Impact blocks that cooperate with the elastic rod are uniformly fixed on the top wall of the horizontal plate. Linkage grooves are uniformly opened on the sealing ring. Inclined blocks are fixedly installed on the side wall of the horizontal plate, and the side of the inclined block near the linkage groove is inclined.

[0011] Furthermore, stirring rings are uniformly fixedly installed on the inner wall of the reaction vessel, and connecting rods are fixedly installed between adjacent stirring rings. An annular plate is slidably installed on the inner wall of the reaction vessel, and an elastic pad is installed between the top wall of the annular plate and the reaction vessel. A round rod is installed between the bottom wall of the annular plate and the stirring rings.

[0012] Furthermore, a push block is fixedly installed on the annular plate, and a push rod that cooperates with the push block is fixedly installed on the rotating rod, and the side wall of the push block is inclined.

[0013] Furthermore, the elastic pad has a cavity, an air inlet valve with its input end connected to the reaction vessel is inserted into the cavity, an exhaust valve is inserted into the cavity, the reaction vessel has an air chamber, the air chamber has evenly distributed air holes connected to the storage tank, and an air pipe extending into the air chamber is fixedly installed on the output end of the exhaust valve.

[0014] Furthermore, the push rod and the push block are arranged symmetrically around the rotating rod in two sets.

[0015] Furthermore, the inner wall of the agitator ring is inclined.

[0016] Furthermore, a scraper is fixedly installed on the rotating rod, and the scraper is in contact with the bottom wall of the reaction vessel.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This scheme sets up a feeding port. The enzyme preparation enters the horizontal tank through the feeding port and vertical groove, and is slowly added into the reaction tank through the feeding hole on the horizontal groove. During the rotation of the reciprocating screw, the sealing ring is moved by the linkage block and vertical rod. As the sealing ring moves downward, it gradually disengages from the feeding port. At this time, the enzyme preparation can be added evenly to the food raw materials through the feeding port, vertical groove, horizontal groove and feeding hole. When the linkage block moves upward, the first spring extends and drives the sealing ring to move upward. During the upward movement of the sealing ring, the feeding port is blocked again. At this time, the enzyme preparation cannot continue to pass through the feeding port, so that the enzyme preparation can be added into the reaction tank in batches, which plays a role in improving the enzymatic hydrolysis effect. (2) This scheme sets up an elastic rod, which drives the horizontal plate to swing back and forth through the linkage groove and inclined block during the up and down movement of the sealing ring. During the back and forth swing of the horizontal plate, the impact block is driven to hit the elastic rod back and forth, and the elastic rod swings back and forth. During the back and forth swing of the elastic rod, the vibration can be transmitted to the storage tank through the hollow rod, thereby ensuring that the powdered enzyme preparation in the storage tank enters the vertical groove through the feeding port normally, and enters the reaction cylinder through the vertical groove, horizontal groove and feeding hole, which further improves the enzymatic hydrolysis effect. (3) This scheme sets up a stirring ring, which drives the ring plate to move up and down repeatedly through the push rod and push block during the rotation of the rotating rod, and causes the elastic pad to stretch and contract back and forth. During the reciprocating movement of the ring plate, the stirring ring moves up and down repeatedly. During the reciprocating movement of the stirring ring, the mixture in the reaction tank can also be stirred vertically, thereby avoiding the sedimentation of food raw materials from affecting the mixing effect of food raw materials and enzyme preparations, and further improving the enzymatic hydrolysis effect. (4) By opening a cavity, the gas in the cavity flows into the gas chamber through the exhaust valve and gas pipe during the compression of the elastic pad, and is evenly blown into the enzyme preparation in the storage tank through the air hole on the gas chamber, thereby ensuring that the enzyme preparation moves normally into the vertical tank through the feeding port. After the air flow passes through the feeding port and flows into the vertical tank, the air flow will drive the enzyme preparation into the reaction tank through the feeding holes on the vertical and horizontal tanks, thereby avoiding the enzyme preparation from getting stuck in the vertical and horizontal tanks and affecting the normal progress of the enzymatic hydrolysis reaction. In addition, when the air flow enters the reaction tank through the feeding hole, the air flow will impact the mixture in the reaction tank, thereby making the food raw materials and enzyme preparation fully mixed, further improving the enzymatic hydrolysis effect.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1 to 8 A pet food enzymatic hydrolysis reaction device includes a reaction tank 1, a motor 2 fixedly installed on the top wall of the reaction tank 1, a reciprocating lead screw 3 fixedly installed on the output end of the motor 2, a rotating rod 4 fixedly installed on the bottom end of the reciprocating lead screw 3, a stirring rod 5 evenly fixedly installed on the rotating rod 4, and a feeding assembly 6 provided on the reaction tank 1. The feeding assembly 6 includes a feeding block 601 fixedly installed on the top plate inside the reaction tank 1. The feeding block 601 has a storage trough 602. The top wall of the reaction tank 1 has an addition groove. A sealing plug 603 is detachably installed in the addition groove. The rotating rod 4 has a vertical groove 604. The stirring rod 5 has a horizontal groove 605 communicating with the vertical groove 604. The horizontal groove 605 has feeding holes 607 evenly distributed. The vertical groove 604 has a feeding port 608 communicating with the storage trough 602. The feeding block 601 is provided with a linkage assembly 7 that cooperates with the feeding port 608.

[0022] The linkage component 7 includes an annular groove formed on the feeding block 601, a sealing ring 701 slidably installed in the annular groove, a first spring 702 jointly installed between the sealing ring 701 and the annular groove, a linkage block 703 threadedly installed on the reciprocating screw 3, a telescopic rod 704 fixedly installed between the top of the linkage block 703 and the reaction tank 1, a vertical rod 705 fixedly installed at the top of the sealing ring 701, a feed inlet opened on the side wall of the reaction tank 1, a stopper plate 706 detachably installed in the feed inlet, and a discharge valve 707 fixedly installed on the bottom wall of the reaction tank 1.

[0023] In use, the prepared food ingredients are introduced into the reaction tank 1 through the feed inlet, and the enzyme preparation is introduced into the storage tank 602 through the addition tank. After adjusting the reaction tank 1 to a suitable environment for enzymatic hydrolysis, the motor 2 is started. The motor 2 then drives the rotating rod 4 to rotate through the reciprocating screw 3. During the rotation of the rotating rod 4, the stirring rod 5 is also rotated to stir the raw materials in the reaction tank 1. At the same time, the enzyme preparation enters the horizontal tank 605 through the feed inlet 608 and the vertical tank 604, and is slowly added into the reaction tank 1 through the feed hole 607 on the horizontal tank 605. The rotating horizontal rod can make the enzyme preparation evenly added to the food ingredients. In addition, the rotating horizontal rod can also stir the enzyme preparation and the food ingredients, thereby making the food ingredients and enzyme preparation evenly mixed and improving the enzymatic hydrolysis effect.

[0024] Since the linkage block 703 is fixedly connected to the inner top wall of the reaction vessel 1 via the telescopic rod 704, the linkage block 703 can only move vertically. During the rotation of the reciprocating screw 3, the linkage block 703 moves up and down along the reciprocating screw 3. As the linkage block 703 moves downwards, it gradually contacts the vertical rod 705 and applies a downward thrust to the vertical rod 705. Under this thrust, the vertical rod 705 drives the sealing ring 701 downwards and compresses the first spring 702. During the downward movement of the sealing ring 701... During the process, the enzyme gradually loses contact with the feed port 608. At this time, the enzyme preparation can normally enter the reaction tank 1 through the feed port 608, vertical groove 604, horizontal groove 605, and feed hole 607. As the linkage block 703 moves upward, the first spring 702 extends and drives the sealing ring 701 to move upward. During the upward movement of the sealing ring 701, the feed port 608 is blocked again. At this time, the enzyme preparation can no longer pass through the feed port 608, so that the enzyme preparation can be added to the reaction tank 1 in batches, which further improves the enzymatic hydrolysis effect.

[0025] like Figure 3 , Figure 4 As shown, hollow rods 801 are uniformly fixedly installed in the storage tank 602, and elastic rods 802 are fixedly installed on the hollow rods 801. The feeding block 601 has a round hole that cooperates with the elastic rods 802. The hollow rods 801 have a shaking groove, and the bottom end of the elastic rods 802 extends into the shaking groove.

[0026] A horizontal plate 803 is horizontally slidably installed in the vibration groove. A second spring 804 is installed between the horizontal plate 803 and the vibration groove. Impact blocks 805 that cooperate with elastic rods 802 are uniformly fixedly installed on the top wall of the horizontal plate 803. Linkage grooves 807 are uniformly opened on the sealing ring 701. An inclined block 806 is fixedly installed on the side wall of the horizontal plate 803, and the side of the inclined block 806 near the linkage groove 807 is inclined.

[0027] By adopting the above technical solution, during the downward movement of the sealing ring 701, the linkage groove 807 is driven to move downward. During this downward movement, the top wall of the linkage groove 807 gradually contacts the inclined surface of the inclined block 806, applying a pushing force to the inclined surface of the inclined block 806. Under this pushing force, the inclined block 806 drives the horizontal plate 803 to move and compress the second spring 804. When the inclined block 806 contacts the linkage groove 807 again, the second spring 804 extends and, through the horizontal plate 803, drives the inclined block 806 back into the linkage groove 807. In other words, during the downward movement of the sealing ring 701, the horizontal plate 803 moves back and forth via the linkage groove 807 and the inclined block 806. The horizontal plate 803 moves back and forth, causing the impact block 805 to move back and forth. During this movement, the impact block 805 gradually comes into contact with the elastic rod 802, causing the elastic rod 802 to deform. After the impact block 805 disengages from the elastic rod 802, the elastic rod 802 swings back and forth under its own elastic force. During this swinging motion, the vibration can be transmitted to the storage tank 602 through the hollow rod 801, thereby ensuring that the powdered enzyme preparation in the storage tank 602 enters the vertical tank 604 through the feeding port 608, and then enters the reaction cylinder through the vertical tank 604, the horizontal tank 605, and the feeding hole 607, further improving the enzymatic hydrolysis effect.

[0028] like Figure 2 , Figure 3 As shown, stirring rings 901 are uniformly fixedly installed on the inner wall of the reaction vessel 1, and connecting rods 902 are fixedly installed between adjacent stirring rings 901. An annular plate 903 is slidably installed on the inner wall of the reaction vessel 1. An elastic pad 904 is installed between the top wall of the annular plate 903 and the reaction vessel 1. A round rod 905 is installed between the bottom wall of the annular plate 903 and the stirring rings 901.

[0029] A push block 906 is fixedly installed on the annular plate 903, and a push rod 907 that cooperates with the push block 906 is fixedly installed on the rotating rod 4, and the side wall of the push block 906 is inclined.

[0030] The elastic pad 904 has a cavity 101, an air inlet valve 102 with its input end connected to the reaction tank 1 is inserted into the cavity 101, an exhaust valve 103 is inserted into the cavity 101, the reaction tank 1 has an air chamber 104, the air chamber 104 has air holes 105 evenly distributed on it and connected to the storage tank 602, and an air pipe 106 extending into the air chamber 104 is fixedly installed on the output end of the exhaust valve 103.

[0031] By adopting the above technical solution, during the rotation of the rotating rod 4, the push rod 907 is driven to rotate, and during the rotation of the push rod 907, it gradually comes into contact with the inclined surface of the push block 906 and applies a pushing force to the inclined surface of the push block 906. Then, under the action of the pushing force, the push block 906 drives the annular plate 903 to move upward and compress the elastic pad 904. During the upward movement of the annular plate 903, the stirring ring 901 is driven to move upward through the round rod 905. During the upward movement of the stirring ring 901, the lower stirring ring 901 is driven to move upward through the connecting rod 902. Then, after the push rod 907 disengages from the push block 906, the elastic pad 904... The rotating rod 4 extends and drives the annular plate 903 downward. During the downward movement of the annular plate 903, the circular rod 905 drives the stirring ring 901 downward. That is, during the rotation of the rotating rod 4, the stirring ring 901 can move up and down repeatedly. During the up and down reciprocating movement of the stirring ring 901, the food raw materials adhering to the inner wall of the reaction vessel can be scraped off, thereby ensuring that the food raw materials and enzyme preparations are mixed evenly. In addition, during the up and down reciprocating movement of the stirring ring 901, the mixture in the reaction vessel 1 can also be stirred vertically, thereby avoiding the sedimentation of food raw materials and affecting the mixing effect of food raw materials and enzyme preparations, and further improving the enzymatic hydrolysis effect.

[0032] During the extension of the elastic pad 904, the cavity 101 draws in gas from the reaction tank 1 through the air inlet valve 102. Then, as the annular plate 903 moves upward and compresses the elastic pad 904, the gas in the cavity 101 flows into the gas chamber 104 through the exhaust valve 103 and the air pipe 106, and is evenly blown into the enzyme preparation in the storage tank 602 through the air holes 105 on the gas chamber 104. This ensures that the enzyme preparation moves normally into the vertical groove 604 through the feeding port 608. After the airflow passes through the feeding port 608 and flows into the vertical groove 604, the airflow will carry the enzyme preparation into the reaction tank 1 through the feeding holes 607 on the vertical groove 604 and the horizontal groove 605. This prevents the enzyme preparation from getting stuck in the vertical groove 604 and the horizontal groove 605, which would affect the normal progress of the enzymatic hydrolysis reaction. In addition, when the airflow enters the reaction tank 1 through the feeding hole 607, the airflow will impact the mixture in the reaction tank 1, thereby making the food raw materials and enzyme preparation fully mixed and further improving the enzymatic hydrolysis effect.

[0033] like Figure 2 , Figure 3 , Figure 5 As shown, the push rod 907 and the push block 906 are arranged symmetrically around the rotating rod 4 in two sets.

[0034] The inner wall of the stirring ring 901 is inclined.

[0035] By adopting the above technical solution, and by symmetrically arranging two sets of push rods 907 and push blocks 906, the annular plate 903 is subjected to uniform force, avoiding uneven force on the annular plate 903 and preventing it from getting stuck. Furthermore, by making the inner wall of the stirring ring 901 inclined, the cleaning effect of the stirring ring 901 on the food raw materials adhering to the inner wall of the reaction vessel 1 can be improved, and a large amount of food raw materials can be avoided from accumulating on the top wall of the stirring ring 901, which would affect the enzymatic hydrolysis effect.

[0036] like Figure 2 , Figure 5 As shown, a scraper 11 is fixedly installed on the rotating rod 4, and the scraper 11 is in contact with the bottom wall of the reaction vessel 1.

[0037] By adopting the above technical solution, the rotating rod 4 can drive the scraper 11 to rotate during the rotation of the rotating rod 4. During the rotation of the scraper 11, the mixture on the bottom wall of the reaction tank 1 can be stirred, thereby improving the enzymatic hydrolysis effect. After the enzymatic hydrolysis is completed, the user opens the discharge valve 707. At this time, the enzymatically hydrolyzed raw material in the reaction tank 1 can flow to the outside through the discharge valve 707. The rotating scraper 11 can promote the normal flow of the raw material on the bottom wall of the reaction tank 1 into the discharge valve 707.

[0038] Instructions for use: When adding enzyme preparation, the rotating rod 4 drives the stirring rod 5 to rotate and stir the raw materials in the reaction tank 1. The enzyme preparation enters the horizontal tank 605 through the feeding port 608 and the vertical groove 604, and is slowly added into the reaction tank 1 through the feeding hole 607 on the horizontal groove 605. During the rotation of the reciprocating screw 3, the linkage block 703 moves up and down along the reciprocating screw 3. During the movement of the linkage block 703, the vertical rod 705 drives the sealing ring 701 to move up and down. As the sealing ring 701 moves downward, it gradually disengages from the feeding port 608. At this time, the enzyme preparation can normally enter the reaction tank 1 through the feeding port 608, the vertical groove 604, the horizontal groove 605, and the feeding hole 607. During the upward movement of the sealing ring 701, the feeding port 608 is sealed again, thus allowing the enzyme preparation to be added into the reaction tank 1 in batches.

[0039] Furthermore, during the movement of the sealing ring 701, the linkage groove 807 is moved, and during the downward movement of the linkage groove 807, the horizontal plate 803 is moved back and forth by the inclined block 806. During the back and forth movement of the horizontal plate 803, the impact block 805 is moved back and forth. During the movement of the impact block 805, it gradually comes into contact with the elastic rod 802 and causes the elastic rod 802 to deform. When the impact block 805 disengages from the elastic rod 802, the elastic rod 802 swings back and forth under its own elastic force. During the back and forth swing of the elastic rod 802, the vibration can be transmitted to the storage tank 602 through the hollow rod 801, thereby ensuring that the powdered enzyme preparation in the storage tank 602 enters the vertical groove 604 normally through the feeding port 608.

[0040] Then, during the rotation of the rotating rod 4, the push rod 907 rotates and the push block 906 drives the annular plate 903 to move up and down repeatedly. During the up and down reciprocating movement of the annular plate 903, the stirring ring 901 moves up and down repeatedly. During the up and down reciprocating movement of the stirring ring 901, the food raw materials adhering to the inner wall of the reaction cylinder can be scraped off. During the up and down reciprocating movement of the stirring ring 901, the mixture in the reaction tank 1 can also be stirred vertically.

[0041] Finally, as the annular plate 903 moves upward and compresses the elastic pad 904, the gas in the cavity 101 flows into the gas chamber 104 through the exhaust valve 103 and the air pipe 106, and is evenly blown into the enzyme preparation in the storage tank 602 through the air holes 105 on the gas chamber 104. This ensures that the enzyme preparation moves normally into the vertical groove 604 through the feeding port 608. After the airflow passes through the feeding port 608 and flows into the vertical groove 604, the airflow will drive the enzyme preparation into the reaction tank 1 through the feeding holes 607 on the vertical groove 604 and the horizontal groove 605. This prevents the enzyme preparation from getting stuck in the vertical groove 604 and the horizontal groove 605, which would affect the normal progress of the enzymatic hydrolysis reaction. In addition, when the airflow enters the reaction tank 1 through the feeding hole 607, the airflow will impact the mixture in the reaction tank 1, thereby ensuring that the food raw materials and the enzyme preparation are fully mixed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
