Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, and in particular to a high-temperature sterilization device. Background Technology

[0002] Existing high-temperature sterilization equipment, such as high-pressure steam sterilizers and pasteurization equipment, is widely used in food processing, medical consumables disinfection, and other scenarios. The former creates a high-pressure, high-temperature steam environment, while the latter uses moderate high-temperature treatment to kill microorganisms, providing a foundation for ensuring product safety and shelf life.

[0003] The working principle of these methods is to use high temperatures to denature and inactivate the proteins, nucleic acids, and other biomolecules of microorganisms, thereby disrupting their structure and function. High-pressure steam sterilization relies on the high temperature and pressure generated by steam accumulation in a sealed space, while pasteurization uses short-duration, relatively mild high temperatures to inhibit microbial growth. However, existing equipment has drawbacks. On the one hand, high temperatures can easily damage the nutritional components and flavor compounds of materials, affecting product quality; on the other hand, traditional equipment has limited temperature control precision, easily leading to incomplete sterilization due to uneven temperature distribution. Furthermore, the operation process is cumbersome, energy consumption is high, and adaptability to different packaging and materials is poor.

[0004] In existing technologies, such as the high-temperature sterilization equipment with publication number CN221866696U, belonging to the field of beer production technology, a sterilization chamber is included. Several rotating shafts are rotatably installed inside the sterilization chamber. Rotary rollers are fixedly installed on the outer surface of each shaft. Two rollers on the same side have drive belts on their outer surfaces, and the two rollers are connected by the drive belts. Several clamping plates are fixedly installed on the outer surface of the drive belts. Two clamping plates on the same horizontal plane cooperate with each other, and drawers are slidably installed on the two clamping plates on the same horizontal plane. By providing an opening and a sealing door, after the top drawer is removed through the upper opening, the movement of the two drive belts drives the clamping plates, causing the drawer to move upwards. At this point, a new round of sterilization can continue through the lower opening. This design reduces heat loss during loading and unloading, allows for continuous sterilization, saves resources, and improves overall sterilization efficiency to meet production needs. However, this design still has some drawbacks. It lacks a dedicated separation and collection mechanism for dust and debris, and it lacks uniform heating of the materials, requiring further improvement.

[0005] Therefore, this application provides a high-temperature sterilization device to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature sterilization device with a simple structure and excellent sterilization efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A high-temperature sterilization device includes a base, with support rods fixedly installed on both sides of the upper end of the base. A support frame is fixedly installed on the lower end of one side of the two support rods, and a connecting column is fixedly connected to the upper end of the other side of the two support rods. A sterilization chamber is fixedly installed at one end of the two connecting columns. A feed inlet is fixedly installed on the upper end of one side of the sterilization chamber, and a discharge outlet is fixedly installed on the lower end of one side of the sterilization chamber. A cover is snapped onto one end of the feed inlet and the discharge outlet. A ventilation chamber is fixedly installed on the lower end of one side of the two support rods. A heating chamber is fixedly installed at one end of the inner wall of the ventilation chamber, and a debris chamber is fixedly installed at the other end of the inner wall of the ventilation chamber.

[0008] Furthermore, an electric motor is fixedly installed at the top center of the upper end of the sterilization chamber, and a rotating shaft is provided at the output end of the electric motor. Several stirring blades are fixedly installed on the outer surface of the rotating shaft.

[0009] Furthermore, air pipes are fixedly installed on the inner walls of the two support rods and the connecting column, and a filter screen is fixedly installed at one end of each of the two air pipes.

[0010] Furthermore, the debris chamber includes a first chute and a first door panel, a first handle is fixedly provided on one side of the front end of the first door panel, and a filter plate is slidably arranged inside the first chute.

[0011] Furthermore, the heating chamber includes a second door panel, a second slide groove, and three support plates, with a second handle fixedly installed on one side of the front end of the second door panel.

[0012] Furthermore, a heating plate and absorbent cotton are slidably disposed on the inner wall of the second chute.

[0013] Furthermore, a motor is fixedly mounted on one end of each of the three support plates, and a fan is mounted on the output end of the motor.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a high-temperature sterilization device with an inclined cylindrical sterilization chamber. Utilizing the characteristics of the inclined surface, the material naturally rolls and moves during sterilization due to the stirring blades and gravity, preventing accumulation and ensuring that each piece of material is evenly subjected to high temperature, thus improving sterilization efficiency and consistency. Simultaneously, the material can slide in smoothly due to the inclined angle during feeding and automatically slide out due to gravity during discharge, eliminating the need for complex conveying devices, simplifying the operation process, saving manpower and time, adapting to various material forms, and providing high efficiency and practicality, facilitating smoother sterilization operations.

[0015] 2. This utility model proposes a high-temperature sterilization device with a dedicated space for collecting dust and debris, greatly improving the device's practicality. During daily operation and maintenance, this space effectively collects dust and debris from external sources, preventing them from mixing with the items to be sterilized and causing secondary contamination, thus ensuring sterilization effectiveness and product quality. Simultaneously, the independent collection space facilitates centralized cleaning, reducing cleaning difficulty and time, keeping the equipment's interior clean, lowering the risk of equipment failure, extending its service life, and providing a reliable guarantee for stable and efficient sterilization operations.

[0018] 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.

[0019] Reference Figure 1 One embodiment provided by this utility model: A high-temperature sterilization device includes a base 1. Support rods 4 are fixedly installed on both sides of the upper end of the base 1. A support frame 2 is fixedly installed on the lower end of one side of the two support rods 4. A connecting column 5 is fixedly connected to the upper end of the other side of the two support rods 4. A sterilization chamber 8 is fixedly installed at one end of the two connecting columns 5. A feed inlet 7 is fixedly installed on the upper end of one side of the sterilization chamber 8. A discharge outlet 9 is fixedly installed on the lower end of one side of the sterilization chamber 8. A cover 6 is snapped onto one end of the feed inlet 7 and the discharge outlet 9. A ventilation chamber 11 is fixedly installed on the lower end of one side of the two support rods 4. A heating chamber 10 is fixedly installed on one end of the inner wall of the ventilation chamber 11. A debris chamber 3 is fixedly installed on the other end of the inner wall of the ventilation chamber 11.

[0020] Specifically, the base 1 is made of high-strength metal, providing stable support for the equipment. The vertically fixed support rods 4 on both sides of its upper end are symmetrically distributed, supporting the sterilization chamber 8. The support frame 2 at the lower end of one side of the support rod 4 has an L-shaped structure, further enhancing the equipment's stability. The connecting column 5 connects the support rod 4 to the sterilization chamber 8, ensuring the sterilization chamber 8 is securely installed. The sterilization chamber 8 is designed as an inclined cylinder with an angle of 15° to the horizontal. This angle ensures that the material rolls smoothly under gravity and the action of the stirring blades, while preventing the material from sliding down too quickly, ensuring sufficient sterilization time. The sterilization chamber 8 is wrapped with a 50mm thick polyurethane heat-insulating shell to reduce heat loss and facilitate material entry and exit and even distribution inside. The inlet 7 and outlet 9 are located at the high and low ends of the sterilization chamber 8, respectively. The cap 6 is sealed with a snap-fit ​​mechanism to prevent heat loss and foreign object entry during sterilization. The ventilation chamber 11 is located at the lower end of one side of the support rod 4. The heating chamber 10 at one end is used to generate high-temperature gas, while the debris chamber 3 at the other end is responsible for collecting dust and debris.

[0021] Reference Figure 2 A motor 12 is fixedly installed at the top center of the sterilization chamber 8. A rotating shaft 13 is installed at the output end of the motor 12. Several stirring blades 15 are fixedly installed on the outer surface of the rotating shaft 13. Air pipes 16 are fixedly installed on the inner walls of the two support rods 4 and the connecting column 5. A filter screen 14 is fixedly installed at one end of the two air pipes 16.

[0022] Specifically, four fixing blocks are provided at the top center of the sterilization chamber 8 as the base of the motor 12 for fixing the motor 12. The motor 12 is a YX3 series high-efficiency energy-saving three-phase asynchronous motor with a power of 5kW and a rated speed of 1450r / min. The rotating shaft 13 is made of 45# high-quality carbon structural steel with a diameter of 30mm and a length customized according to the size of the sterilization chamber 8. The stirring blades 15 are made of 304 stainless steel with a blade length of 200mm, a width of 80mm, and a thickness of 5mm. They are arranged in a spiral shape and drive the material to tumble under the drive of the motor 12. Combined with the tilt angle of the sterilization chamber 8, the material is uniformly heated and sterilized. The trachea 16 is made of stainless steel with a diameter of 50mm, which runs through the inner wall of the support rod 4 and the connecting column 5. Its inner wall is smooth to reduce the resistance to gas flow. The filter screen 14 at one end can filter the gas entering the trachea 16 and effectively prevent impurities from entering the sterilization chamber 8. The filter screen 14 is made of stainless steel wire mesh with a filtration accuracy of 5μm. It can effectively intercept dust, particles and other impurities, and is easy to disassemble and clean. The other ends of the two sections of the trachea 16 are connected to the two ends of the ventilation chamber 11 respectively to form a circulation.

[0023] Reference Figure 3 The debris chamber 3 includes a first slide 304 and a first door panel 302. A first handle 301 is fixedly provided on one side of the front end of the first door panel 302, and a filter plate 303 is slidably provided inside the first slide 304.

[0024] Specifically, the first door panel 302 of the debris chamber 3 is connected to the side of the ventilation chamber 11 via a hinge, and the first handle 301 at the front end facilitates opening and closing. The first slide groove 304 is horizontally set on the upper and lower inner walls of the debris chamber 3. The surface of the filter plate 303 is treated with a nano-coating, which has oleophobic and hydrophobic properties, making it difficult for dust and debris to adhere. It can be slid out along the first slide groove 304 to intercept and collect dust and debris. Cleaning can be completed simply by pulling out the filter plate 303. At the same time, a vibration device is set at the bottom of the debris chamber 3. When cleaning the filter plate 303, the vibration device is activated, which can make the debris on the filter plate 303 fall off quickly, making cleaning easier.

[0025] Reference Figure 4 The heating chamber 10 includes a second door panel 1002, a second slide groove 1004 and three support plates 1007. A second handle 1001 is fixedly installed on one side of the front end of the second door panel 1002. A heating plate 1003 and absorbent cotton 1006 are slidably installed on the inner wall of the second slide groove 1004. A motor 1005 is fixedly installed at one end of the three support plates 1007, and a fan 1008 is installed at the output end of the motor 1005.

[0026] Specifically, the second door panel 1002 of the heating chamber 10 is also connected to the upper end of the ventilation chamber 11 via a hinge, and the second handle 1001 facilitates operation. The second sliding groove 1004 is located on the left and right inner walls of the heating chamber 10, where the heating plate 1003 can be slidably installed. It uses resistance wire heating, and the heating power can be adjusted within the range of 0-10kW. Precise temperature control is achieved through an intelligent temperature controller, with a temperature control range of 100℃-300℃ and an accuracy of ±2℃. The surface of the heating plate 1003 is coated with a high-temperature resistant and corrosion-resistant coating to extend its service life and provide a heat source for the sterilization process. The absorbent cotton 1006 absorbs the moisture generated during heating, ensuring the dryness of the high-temperature gas. Three support plates 1007 are vertically and evenly distributed along the left and right bottom directions of the inner wall of the heating chamber 10. A motor 1005 fixed at one end drives a fan 1008 to rotate, evenly blowing out the heat generated by the heating plate 1003, which is then sent into the sterilization chamber 8 through the air pipe 16.

[0027] Working Principle: Before starting the equipment, open the cover 6 of the feed inlet 7 and place the material to be sterilized into the sterilization chamber 8. After closing the cover 6, the heating plate 1003 of the heating chamber 10 starts working. The motor 1005 drives the fan 1008 to send the high-temperature gas generated by the heating plate 1003 into the sterilization chamber 8 through the air pipe 16 and the filter screen 14. At the same time, the motor 12 drives the rotating shaft 13 and the stirring blade 15 to rotate. Combined with the tilt angle of the sterilization chamber 8, the material continuously rolls and moves in the high-temperature environment to achieve uniform sterilization. During this process, the dust and debris generated enter the ventilation chamber 11 through the airflow and are intercepted and collected by the filter plate 303 of the debris chamber 3. After sterilization is completed, open the cover 6 of the discharge port 9, and the material is discharged from the discharge port 9 under the action of gravity. The first door panel 302 can be opened periodically through the first handle 301 to remove the filter plate 303 and clean the debris; the second door panel 1002 can be opened through the second handle 1001 to inspect and replace the heating plate 1003 and the absorbent cotton 1006, ensuring the continuous and stable operation of the equipment.
