Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology in starch production, specifically a heat treatment device for resistant starch production. Background Technology

[0002] Resistant starch, also known as enzyme-resistant starch or indigestible starch, is a substance that cannot be broken down by enzymes in the small intestine, but can undergo fermentation with volatile fatty acids in the human gastrointestinal tract, specifically the colon.

[0003] A search revealed an existing patent (publication number: CN215743467U) that discloses a heat treatment device for resistant starch production. The device includes a reaction chamber with several U-shaped troughs. A closed oil bath is formed between the sidewalls of each U-shaped trough, or between the sidewalls of the U-shaped troughs and the sidewalls or bottom of the reaction chamber. Several partitions are installed at the bottom of the reaction chamber, corresponding to the connection points between the U-shaped troughs or near the sidewalls of the reaction chamber. Connecting plates are installed on the upper part of the sidewalls at both ends of the reaction chamber, screwed to a pressure cap located at the top of the reaction chamber. A material inlet is located in the center of the pressure cap, and a stirring device is installed on the pressure cap corresponding to the center of each U-shaped trough. The stirring shaft of the stirring device extends into the U-shaped trough. Both ends of the pressure cap are connected to a gantry crane via hooks. This device integrates multiple heating and cooling processes into a single unit, reducing material oxidation and contamination, shortening the production cycle, and improving product quality.

[0004] It combines heat treatment and refrigeration to reduce equipment usage, but it has shortcomings. After refrigeration, the starch will age and solidify, becoming fixed on the stirring mechanism, making it difficult to remove later. Also, the hot and cold media enter through one oil inlet and exit through one oil outlet, requiring replacement of the hot and cold media inlet and outlet pipes, or adjustment of the hot and cold media inlet and outlet by opening and closing multiple valves, thus increasing the workload of the staff. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a heat treatment device for the production of resistant starch, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat treatment device for resistant starch production, comprising a barrel body, a mounting frame fixed to the top of the barrel body, a motor fixed to the top of the mounting frame, a transmission gear fixed to the outer wall of the output shaft of the motor, a plurality of stirring rods rotatably connected inside the barrel body, a rotating gear fixed to the top of the stirring rods, the transmission gear and the rotating gear meshing with each other, and a heat exchange cylinder fixed to the outer wall of the barrel body, the heat exchange cylinder having two circular grooves inside;

[0007] The heat exchange cylinder has multiple annular heat exchange grooves between the two circular grooves inside. The cylinder body is equipped with a heat exchange efficiency improvement mechanism, which includes a fixed cylinder, a spiral conveying blade, and a bell mouth. Multiple support rods are fixed to the outer wall of the bell mouth, and the other end of the support rods is fixedly connected to the inner wall of the cylinder body. A fixed cylinder is fixed to the bottom of the bell mouth. The fixed cylinder is equipped with a spiral conveying blade inside. The top of the spiral conveying blade is fixedly connected to the bottom end of the output shaft of the motor. A feed pipe is fixed to the top of the cylinder body, and a sealing cap is screwed to the bottom of the cylinder body.

[0008] Preferably, the bottom of the barrel is fixed with multiple support legs.

[0009] Preferably, the diameter of the transmission gear is larger than the diameter of the rotating gear.

[0010] Preferably, the outer wall of the heat exchange cylinder is provided with two liquid inlet mechanisms. Each liquid inlet mechanism includes two fixing blocks. Two connectors are fixed on the side of the fixing blocks away from the cylinder body. Two flow grooves are opened inside the fixing blocks. A lower spring is fixed inside the lower flow groove. A sealing block is fixed at the other end of the lower spring.

[0011] Preferably, the sealing block has multiple perforations on its left side, and a sliding groove is fitted into the inner wall of the upper flow channel. A movable block is slidably connected inside the sliding groove. A round hole is opened at the bottom of the movable block, and an upper spring is fixed inside the round hole. A pull rope is fixed to the side of the sealing block near the barrel body, and the other end of the pull rope is fixedly connected to the upper surface inside the round hole.

[0012] Preferably, the elastic force of the lower spring is greater than that of the upper spring. Beneficial effects

[0013] This invention provides a heat treatment apparatus for the production of resistant starch. Compared with the prior art, it has the following advantages:

[0014] 1. The heat treatment device for resistant starch production, by setting up a heat exchange efficiency improvement mechanism, starts the motor, and the motor drives the spiral conveyor blade to rotate, which can make the starch on the inner side below move upward. The rising starch slides outward from the funnel mouth, which can rotate the positions of the starch on the inner and outer sides and accelerate the temperature rise of the starch on the inner side.

[0015] 2. This heat treatment device for resistant starch production, through the setting of a liquid inlet mechanism, connects an external pipeline to the connector. If the hot medium enters from the lower left connector, it will push the left-side sealing block, which moves to the right. Then, the hot medium passes through the perforation and enters the heat exchange cylinder to heat the cylinder. The sealing block moves to loosen the pull rope, and the upper spring pushes the moving block to move. The moving block seals the upper left flow channel, preventing the hot medium from passing through and allowing it to flow out from the upper right flow channel. When cooling, the cooling medium enters from the lower right connector. The above operation is repeated, thus eliminating the need to regulate the flow of the medium through valves.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a heat treatment device for resistant starch production, including a barrel 8, a mounting frame 7 fixed to the top of the barrel 8, a motor 9 fixed to the top of the mounting frame 7, a transmission gear 11 fixed to the outer wall of the output shaft of the motor 9, multiple stirring rods 19 rotatably connected inside the barrel 8, a rotating gear 10 fixed to the top of the stirring rods 19, and the transmission gear 11 and the rotating gear 10 meshing with each other, a heat exchange cylinder 3 fixed to the outer wall of the barrel 8, two circular grooves 13 opened inside the heat exchange cylinder 3, and multiple annular heat exchange grooves 12 opened between the two circular grooves 13 inside the heat exchange cylinder 3, and a heat exchange efficiency improvement mechanism 15 provided inside the barrel 8, improving the heat exchange efficiency. The lifting mechanism 15 includes a fixed cylinder 20, a spiral conveyor blade 14, and a bell mouth 16. Multiple support rods 17 are fixed to the outer wall of the bell mouth 16, and the other end of the support rods 17 is fixedly connected to the inner wall of the barrel 8. The fixed cylinder 20 is fixed to the bottom of the bell mouth 16. The spiral conveyor blade 14 is provided inside the fixed cylinder 20. The top of the spiral conveyor blade 14 is fixedly connected to the bottom end of the output shaft of the motor 9. The feed pipe 6 is fixed to the top of the barrel 8, and a sealing cover 2 is screwed to the bottom of the barrel 8. This can improve the heat exchange efficiency of the starch inside. Multiple support legs 1 are fixed to the bottom of the barrel 8, which can raise the height of the device. The diameter of the transmission gear 11 is larger than the diameter of the rotating gear 10.

[0024] Furthermore, the outer wall of the heat exchange cylinder 3 is provided with two liquid inlet mechanisms 5. The liquid inlet mechanism 5 includes two fixed blocks 18. Two connectors 4 are fixed on the side of the fixed block 18 away from the barrel body 8. Two flow grooves 26 are opened inside the fixed block 18. A lower spring 21 is fixed inside the lower flow groove 26. A blocking block 23 is fixed to the other end of the lower spring 21. Multiple perforations 22 are opened on the left side of the blocking block 23. A sliding groove 27 is provided on the inner wall of the upper flow groove 26. A moving block 25 is slidably connected inside the sliding groove 27. A round hole 28 is opened at the bottom of the moving block 25. An upper spring 29 is fixed inside the round hole 28. A pull rope 24 is fixed on the side of the blocking block 23 near the barrel body 8. The other end of the pull rope 24 is fixedly connected to the inner upper surface of the round hole 28. This can control the flow of the heat exchange medium. The elastic force of the lower spring 21 is greater than that of the upper spring 29, so that the blocking block 23 can move and pull the moving block 25.

[0025] During operation, the external pipe is connected to connector 4. If the hot medium enters from connector 4 at the lower left, it will push the left-side sealing block 23, causing it to move to the right. The hot medium then passes through the perforation 22 and enters the heat exchange cylinder 3, heating the cylinder 8. Moving the left-side sealing block 23 releases the pull rope 24, and the upper spring 29 pushes the left-side moving block 25, sealing the upper left flow channel 26 to prevent the hot medium from passing through. This allows the hot medium to flow out from the upper right flow channel 26, thus heat-treating the starch. After heat treatment, cooling is performed to facilitate subsequent refrigeration. Cooling requires temperature control to prevent the starch from aging and solidifying due to excessively low temperatures, making it difficult to leak from the cylinder 8. During cooling, the cooling medium enters from the lower right connector 4, thus the moving block 25 on the right closes the upper right flow channel 26, and the cooling medium flows out from the upper left flow channel 26. This prevents hot and cold media from entering each other's pipes during heat exchange, eliminating the need to regulate the flow of the medium through valves, making it simple and convenient. During heating, the motor 9 is started, and the motor 9 drives the spiral conveyor blade 14 to rotate, which causes the starch on the lower inner side to rise and move. The rising starch slides outward from the flared mouth 16, which allows the positions of the starch on the inner and outer sides to alternate, accelerating the temperature rise of the starch on the inner side. In addition, the motor 9 also drives the stirring rod 19 to rotate through the transmission gear 11 and the rotating gear 10, stirring the starch.
