Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, specifically to an ultra-high temperature instantaneous sterilization device capable of continuous production. Background Technology

[0002] An instant sterilization device is a type of equipment that can bring materials to a high temperature and complete the sterilization process in a very short time. It is usually equipped with a dedicated sterilization pipeline. After the fluid material to be sterilized enters the device, it first undergoes preliminary heat exchange with a high-temperature environment in the preheating zone to raise its temperature. Then it enters the high-temperature sterilization zone, where, with the help of heat sources such as high-temperature steam, the material is heated to an ultra-high temperature in a very short time, rapidly killing various microorganisms in the material, including bacteria and spores. Afterward, the material is quickly cooled and discharged from the device. The entire process is highly efficient and rapid, ensuring good sterilization results while minimizing quality deterioration problems such as nutrient loss and flavor changes caused by prolonged high-temperature treatment. It is suitable for the sterilization of fluid materials in the food, beverage, and pharmaceutical industries.

[0003] In existing sterilization devices, when materials are sterilized by high-temperature steam, they are transported within a spiral pipe. Water droplets easily condense on the outer wall of the pipe, and because the pipe is spiral, the water droplets at the top can easily drip back down. If these water droplets drip back onto the high-temperature pipe, they will form a heat insulation layer on the pipe surface, hindering the transfer of heat to the fluid inside the pipe, reducing heat exchange efficiency, prolonging the time it takes for the fluid to reach an ultra-high temperature state, and the limited contact area between the high-temperature steam and the pipe wall results in insufficient heat transfer and a slow rate of fluid heating, thus affecting the sterilization effect.

[0004] To address the aforementioned issues, we propose an ultra-high temperature instantaneous sterilization device capable of continuous production. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-high temperature instantaneous sterilization device that can be continuously produced, so as to solve the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuously producing ultra-high temperature instantaneous sterilization device, comprising a sterilization tank body, a vertically upward high-temperature sleeve fixedly disposed at the center of the bottom inner wall of the sterilization tank body, a double-helix sterilization tube installed inside the sterilization tank body, the double-helix sterilization tube comprising an externally threaded preheating tube and an internally threaded high-temperature tube, the externally threaded preheating tube being located outside the high-temperature sleeve, the internally threaded high-temperature tube being located inside the high-temperature sleeve, the top ends of the externally threaded preheating tube and the internally threaded high-temperature tube being connected by a pipe, a guide plate being fixedly welded to the bottom outer wall of the internally threaded high-temperature tube and the externally threaded preheating tube, and heat-conducting fins being fixedly welded to the top outer wall of the internally threaded high-temperature tube and the externally threaded preheating tube.

[0007] Preferably, the guide plate has an inverted "Y" shaped structure, and the distance between the two bottom ends of the guide plate is greater than the diameter of the inner spiral high-temperature tube and the outer thread preheating tube.

[0008] Preferably, one end of the externally threaded preheating tube is connected to a feed pipe, and a feed pipe connector is fixedly provided on the outer wall of one end of the feed pipe. One end of the internally spiral high-temperature tube is connected to a discharge pipe, and a discharge pipe connector is fixedly provided on one end of the discharge pipe.

[0009] Preferably, a high-temperature steam pipe is fixedly installed at the top center of the sterilization tank body through an opening, and a steam pipe connector is fixedly installed on the outer wall of one end of the high-temperature steam pipe.

[0010] Preferably, a drain pipe is connected to the center of the bottom of the sterilization tank body, and a drain pipe connector is fixedly provided on the outer wall of one end of the drain pipe.

[0011] Preferably, a pressure gauge and a thermometer are installed on one outer wall of the sterilization tank body, and the detection ends of the pressure gauge and the thermometer are both located inside the sterilization tank body.

[0012] Preferably, an annular support plate is fixedly provided on the bottom outer wall of the sterilization tank body, and support legs are fixedly provided at equal intervals on the bottom outer wall of the annular support plate.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The increased heat-conducting fins on the internal spiral high-temperature tube and the external thread preheating tube enhance the contact area with high-temperature steam, enabling more efficient heat transfer to the fluid inside the tube. This allows the fluid to reach ultra-high temperature for sterilization in a short time. The inverted "Y"-shaped guide plate at the bottom of the internal spiral high-temperature tube and the external thread preheating tube guides the flow of condensed water droplets on their outer walls, preventing them from dripping back onto the tube and affecting heat exchange efficiency. Simultaneously, the guide plate further absorbs heat, increasing the heat exchange effect and significantly improving the heating rate within the internal spiral high-temperature tube and the external thread preheating tube, thus enhancing the instantaneous sterilization effect.

A drain pipe 12 is connected at the bottom center of the sterilization tank body 1, and a drain pipe connector 13 is fixedly installed on the outer wall of one end of the drain pipe 12. A pressure gauge 18 and a thermometer 19 are installed on one side of the outer wall of the sterilization tank body 1. The detection ends of the pressure gauge 18 and the thermometer 19 extend into the sterilization tank body 1 to detect the internal pressure and temperature. An annular support plate is fixedly installed on the bottom outer wall of the sterilization tank body 1. 16. The bottom outer wall of the annular support plate 16 is fixed with equally spaced support legs 17 to support this utility model. In use, the material enters the external thread preheating pipe 4 from the feed pipe joint 7 through the feed pipe 6 for preheating, and then enters the internal spiral high temperature pipe 5 for ultra-high temperature instantaneous sterilization. The sterilized material is discharged from the discharge pipe 8 through the discharge pipe joint 9. High temperature steam enters the sterilization tank body 1 from the steam pipe joint 11 through the high temperature steam pipe 10 to provide the high temperature required for sterilization. The liquid generated during the sterilization process is discharged from the drain pipe 12 through the drain pipe joint 13. The pressure gauge 18 and the thermometer 19 monitor the pressure and temperature inside the sterilization tank body 1 in real time.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-5 When this utility model is used, the fluid material to be sterilized is first fed into the external thread preheating pipe 4 through the feed pipe 6 from the feed pipe joint 7. In the external thread preheating pipe 4, the fluid flows along the spiral pipe and undergoes preliminary heat exchange with the high temperature environment inside the sterilization tank body 1 to preheat the fluid material and gradually increase the fluid temperature.

[0033] The preheated fluid enters the inner spiral high-temperature tube 5 through a pipe. High-temperature steam enters the sterilization tank body 1 from the steam pipe joint 11 through the high-temperature steam pipe 10. The high-temperature steam fills the internal space of the sterilization tank body 1, especially inside the high-temperature sleeve 2. The heat-conducting fins 15 on the inner spiral high-temperature tube 5 and the outer thread preheating tube 4 increase the contact area with the high-temperature steam, which can more efficiently transfer heat to the fluid inside the tube, allowing the fluid to reach an ultra-high temperature state in a short time. The inverted "Y" shaped guide plate 14 is located at the bottom of the inner spiral high-temperature tube 5 and the outer thread preheating tube 4. 14 can guide the flow of condensed water droplets on its outer wall, allowing them to drip off through both sides of the guide plate 14, preventing water droplets from dripping back onto the internally threaded high-temperature tube 5 and the externally threaded preheating tube 4, thus avoiding water droplets affecting heat exchange efficiency. At the same time, the guide plate 5 can further absorb heat, increase the heat exchange effect, and greatly improve the heating rate inside the internally threaded high-temperature tube 5, which is beneficial to improving the instantaneous sterilization effect. The sterilized fluid is discharged from the discharge pipe 8, while the condensate generated during the sterilization process is discharged from the drain pipe 12. The pressure gauge 18 and the thermometer 19 monitor the pressure and temperature inside the sterilization tank body 1 in real time.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
