Abstract
Description
Technical Field
[0001] This utility model relates to the field of enzyme technology, specifically a high-temperature sterilization system for enzyme production lines. Background Technology
[0002] Enzymes are chemically based on proteins or RNA, and therefore possess primary, secondary, tertiary, and even quaternary structures. Based on their molecular composition, they can be divided into simple enzymes and conjugated enzymes. Simple enzymes contain only proteins; conjugated enzymes consist of an enzyme protein and a cofactor. For example, most hydrolases are composed solely of proteins; flavin mononucleotide enzymes, on the other hand, consist of an enzyme protein and a cofactor. In conjugated enzymes, the enzyme protein is the protein portion, and the cofactor is the non-protein portion; only when both are combined to form a holoenzyme do they possess catalytic activity.
[0003] An enzyme production line is a technological process involving the large-scale production and application of enzyme preparations. It includes key steps such as enzyme generation, enzyme preparation, and enzyme and cell immobilization. In an enzyme production line, high-temperature sterilization equipment is crucial. It is mainly used to kill microorganisms to ensure the safety and stability of the product. During the enzyme production process, high-temperature sterilization can be carried out by ultra-high temperature instantaneous sterilization equipment, high-temperature steam sterilization equipment, or high-temperature sterilization processing equipment.
[0004] However, when using an ultra-high temperature instantaneous sterilization device to sterilize enzymes, it is necessary to first rapidly raise the internal temperature of the equipment to 135-150°C and hold it for 2-8 seconds, then quickly cool it down to 30-40°C to utilize the temperature difference for sterilization. When this equipment is used repeatedly in a short period of time, the heating inner tank inside the equipment will repeatedly experience high temperatures and rapid cooling. Multiple relatively drastic temperature changes in a short period of time will accelerate the aging of the heating inner tank, thus affecting its service life. Therefore, this does not meet the existing requirements. To address this, we propose a high-temperature sterilization system for enzyme production lines. Utility Model Content
[0005] The purpose of this invention is to provide a high-temperature sterilization system for enzyme production lines, addressing the issues raised in the background art where, when using an ultra-high temperature instantaneous sterilization device to sterilize enzymes, the internal temperature of the equipment needs to be rapidly raised to 135-150°C and held for 2-8 seconds before being quickly cooled to 30-40°C to utilize the temperature difference for sterilization. When this equipment is used repeatedly in a short period, the heating inner tank will repeatedly experience high temperatures and rapid cooling, and these repeated, drastic temperature changes will accelerate the aging of the heating inner tank, thus affecting its service life.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature sterilization system for an enzyme production line, comprising a high-temperature instantaneous sterilizer.

The second heating inner liner from the left has an inner liner placement groove located at the middle position of the upper end face of the high-temperature instantaneous sterilizer on the outer side. The outer surface of the heating inner liner is in contact with the inner wall of the inner liner placement groove.
[0007] Preferably, a control panel is fixedly installed on one side of the outer surface of the high-temperature instant sterilizer, and both the high-temperature instant sterilizer and the stepper motor are electrically connected to the control panel.

This technical solution prevents a single heating inner chamber from experiencing multiple temperature changes in a short period of time, thereby improving the service life of the heating inner chamber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] The high-temperature instant sterilizer 1 (model UHT-3), stepper motor 2 (model DM542), and lifting threaded rod 3 (model M20) mentioned in this utility model can be obtained from the market or through private customization.
[0022] Please see Figures 1 to 4This utility model provides an embodiment of a high-temperature sterilization system for an enzyme production line, comprising a high-temperature instantaneous sterilizer 1. A stepper motor 2 is fixedly installed on one side of the bottom end of the high-temperature instantaneous sterilizer 1. The output shaft of the stepper motor 2 is connected to a lifting threaded rod 3 via a coupling. The upper end face of the lifting threaded rod 3 is connected to a top plate 4 via a roller bearing. A guide rod 5 is fixedly provided on both sides of the lower end face of the top plate 4. A lifting sleeve 6 is sleeved on the upper side of the outer surface of the two guide rods 5. The lifting threaded rod 3 vertically penetrates the lifting sleeve 6 from the middle position of the upper end face of the lifting sleeve 6, and the lifting threaded rod 3 and the lifting sleeve... The components 6 are connected by a threaded structure. An electric rotating sleeve 7 is installed in the middle of the outer surface of the lifting sleeve 6. A connecting rod 8 is fixedly installed on both sides of the outer surface of the electric rotating sleeve 7. A sealing cap 9 is fixedly provided on the lower end face of the connecting rod 8. A threaded connector 10 is fixedly provided in the middle of the lower end face of the sealing cap 9. A heating inner liner 11 is threadedly connected to the outer side of the threaded connector 10. An inner liner placement groove 14 is located in the middle of the upper end face of the high-temperature instantaneous sterilizer 1 on the outer side of the second heating inner liner 11 from the left. The outer surface of the heating inner liner 11 is in contact with the inner wall of the inner liner placement groove 14.
[0023] A control panel 18 is fixedly installed on one side of the outer surface of the high-temperature instant sterilizer 1, and both the high-temperature instant sterilizer 1 and the stepper motor 2 are electrically connected to the control panel 18; the high-temperature instant sterilizer 1 and the stepper motor 2 can be controlled through the control panel 18.
[0024] The heating inner liner 11 contains an enzyme placement rack 12, which includes a metal rod, a base, a pull ring, and multiple circular enzyme placement trays. These circular enzyme placement trays are sequentially fixed to the outer surface of the metal rod from top to bottom. The base is fixed to the lower end face of the metal rod, and the pull ring is fixed to the upper end face of the metal rod. When the equipment is needed, first rotate the heating inner liner 11 located on the outside to detach it from the threaded connector 10. Then, pull out the enzyme placement rack 12 inside the heating inner liner 11 using the pull ring, and add enzyme to the circular enzyme placement trays. After adding the enzyme, put the enzyme placement rack 12 back into the heating inner liner 11. Then, reinstall the heating inner liner 11 back into its original position using the threaded structure between the heating inner liner 11 and the threaded connector 10. After the heating inner liner 11 containing the enzyme is installed, start the stepper motor 2. The stepper motor 2 drives the connected lifting threaded rod 3 to rotate. Since the lifting threaded rod 3 is fitted onto the outer surface of the lifting threaded rod... The lifting sleeve 6, which is threaded to the surface, is pierced by two guide rods 5. Therefore, the lifting sleeve 6 cannot rotate on its own. When the lifting threaded rod 3 rotates, the lifting sleeve 6, which is threaded to it but cannot rotate on its own, will move up and down accordingly. At this time, the lifting sleeve 6 moves upward. As the lifting sleeve 6 rises, the electric rotating sleeve 7 installed on the outer surface of the lifting sleeve 6 and the sealing cap 9 connected to the electric rotating sleeve 7 by two connecting rods 8 will also move upward. As the two sealing caps 9 rise, the heating inner liner 11 installed on the lower end face of the two sealing caps 9 will also move upward. When the heating inner liner 11, which was originally located inside the inner liner placement groove 14, completely leaves the inside of the inner liner placement groove 14, the electric rotating sleeve 7 swaps the positions of the two heating inner liner 11. Then, the stepper motor 2 moves the two heating inner liner 11 downward synchronously. As the two heating inner liner 11 descends, the heating inner liner 11 containing enzymes will gradually enter the inside of the inner liner placement groove 14.
[0025] An electrical connector 13 is located at the center of the lower end face of the heating inner liner 11. A second electrical connector 15, fixed to the inner wall of the inner liner placement slot 14 and electrically connected to the high-temperature instantaneous sterilizer 1, is inserted into the second electrical connector from left to right within the electrical connector 13. As the heating inner liner 11 descends, the electrical connector 15, fixed to the inner wall of the inner liner placement slot 14, gradually enters the electrical connector 13 located on the lower end face of the heating inner liner 11. Once the second electrical connector 15 is fully inserted into the electrical connector 13, the high-temperature instantaneous sterilizer 1 and the heating inner liner 11 are electrically connected. Activating the heating inner liner 11 then raises the temperature of the inner liner 11 located inside the inner liner placement slot 14. The heating inner liner 11 is then raised to 135–150°C and maintained for 2–8 seconds. The temperature is then rapidly cooled to 30-40°C to sterilize the enzymes inside using the temperature difference. During the enzyme sterilization process, the enzymes are added to the heated inner liner 11, which is moved to the outside of the inner liner placement tank 14, using the above-mentioned feeding method. After the enzymes inside the inner liner placement tank 14 have undergone high-temperature sterilization, the positions of the two heated inner liners 11 are swapped using the above-mentioned operation method. The above technical solution allows for the cyclical use of the two heated inner liners 11. When one of the heated inner liners 11 has just experienced a relatively drastic temperature change inside the high-temperature instantaneous sterilizer 1, this heated inner liner 11 can be moved to the outside, and the other heated inner liner 11, which was originally located outside, can be installed inside the high-temperature instantaneous sterilizer 1 for use, thereby improving the service life of the heated inner liners 11.
[0026] An annular sealing groove is provided on the outer side of the lower end face of the sealing cap 9. A sealing ring fixed to the upper end face of the high-temperature instant sterilizer 1 is provided inside the second annular sealing groove from the left. The outer surface of the sealing ring is in contact with the inner wall of the annular sealing groove. As the heating inner liner 11 is inserted into the inner liner placement groove 14, the sealing ring located on the upper end face of the high-temperature instant sterilizer 1 will gradually enter the annular sealing groove located on the lower end face of the sealing cap 9. The sealing ring and the annular sealing groove can improve the sealing strength between the sealing cap 9 and the high-temperature instant sterilizer 1, thereby preventing the hot air inside the high-temperature instant sterilizer 1 from leaking to the outside.
[0027] A square groove 16 is provided on the upper side of the front and rear end faces of the heating inner liner 11, and a rotating handle 17 is fixedly installed inside the square groove 16; the rotating handle 17 fixed to the inner wall of the square groove 16 can make it easier to rotate the heating inner liner 11.
[0028] A square metal cover plate is provided on one side of the stepper motor 2, located on the outer surface of the bottom end of the high-temperature instant sterilizer 1, and the high-temperature instant sterilizer 1 is fixed to the square metal cover plate by screws; the square metal cover plate can protect the stepper motor 2, and when the stepper motor 2 fails, the square metal cover plate can be removed for repair.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
