[0002] In the food, pharmaceutical, and cosmetic industries, pasteurization of aerosols is a key process to ensure product safety and stability. Existing pasteurization equipment for aerosols typically includes core structures such as a spray system, a heating sterilization chamber, and a cooling system. By atomizing the liquid and then sterilizing it at low temperatures, the active ingredients and flavor of the product are preserved. However, in actual production, the sterilized aerosols often suffer from frequent product quality problems due to the lack of effective filtration measures at the discharge stage.

[0003] Pasteurization equipment is mainly used in the food, beverage, pharmaceutical, and cosmetic industries. It kills microorganisms through gentle heating while preserving the nutritional components, flavor, and active substances of the product to the maximum extent. It keeps the liquid at a constant temperature for a certain period of time to ensure that the microorganisms are killed.

[0004] The discharge pipe of existing pasteurization equipment is directly connected to the storage tank or subsequent filling equipment. However, during the sterilization process, impurities such as metal fragments, microbial clumps, and coating particles peeling off the inner wall of the pipe may be mixed in due to contact with the inside of the tank or equipment wear. If these impurities are not intercepted, they will not only affect the appearance quality of the product, but may also carry microorganisms that have not been completely killed, causing the product to deteriorate during storage or use, posing food safety or quality safety risks.

The ends of the two limiting blocks 15 near the first limiting block grooves 12 extend slidably to the outside of the second limiting block grooves 14 and are slidably connected to the interior of the corresponding first limiting block grooves 12. Second pull rods 10 are slidably connected to the outer walls of the protective shells on the upper surfaces of the two protrusions on the filter tank 7. The ends of the two first pull rods 9 near the limiting blocks 15 extend slidably to the inside of the second limiting block grooves 14 and are fixedly connected to the outer walls of the corresponding limiting blocks 15. Next, the upper surface protective shells of the two protrusions on the filter tank 7 are respectively connected to the interior of the corresponding second limiting block groove 14. The outer walls of the two first pull rods 9 are each fitted with a first return spring 19. The two ends of the two first return springs 19 are respectively fixedly connected to the outer wall of the corresponding limiting block 15 and the inner wall of the second limiting block groove 14. The upper surface protective shells of the two protrusions on the filter tank 7 are each slidably connected with a fixed slider 16. The ends of the two fixed sliders 16 near the limiting block 15 are slidably extended into the interior of the second limiting block groove 14 and are away from the end of the limiting block 15 away from the first limiting block groove 12. The outer wall has a groove for contact with the inner wall. The ends of the two second pull rods 10 near the fixed slider 16 slide into the interior of the protective shell and are fixedly connected to the upper surface of the corresponding fixed slider 16. The ends of the two slide rods on the outer wall of the two protrusions on the filter tank 7 near the limiting block 15 slide into the interior of the second limiting block groove 14 and are fixedly connected to the outer wall of the corresponding limiting block 15. The outer walls of the two second pull rods 10 are each sleeved with a second return spring 20. The two ends of the two second return springs 20 are fixedly connected to the outer wall of the corresponding fixed slider 16 and the inner wall of the protective shell, respectively.

[0034] The tank 2 has a motor 5 fixedly connected to its upper surface, a storage component 4 fixedly installed on its upper surface, a stirring shaft 18 rotatably connected inside the tank 2, the output end of the motor 5 rotatably extending into the tank 2 and fixedly connected to one end of the stirring shaft 18, the tank 2 fixedly installed on the upper surface of the base 1, a water pump 3 fixedly connected to the outer wall of one side of the upper end of the tank 2, the water inlet of the water pump 3 connected to the storage component 4 through a connecting pipe, a feed pipe 6 fixedly connected to the upper surface of the tank 2, the inside of the feed pipe 6 communicating with the inside of the tank 2, a spray component 17 installed on the inner wall of the tank 2, the spray component 17 consisting of multiple spray heads and a mounting plate, the water outlet of the water pump 3 connected to the multiple spray heads on the spray component 17 through a connecting pipe, and the storage component 4 consisting of a storage box, an electric heating wire, and a control panel.

[0035] Furthermore, when using this device, the spray liquid to be sterilized is stored in the storage tank of the storage component 4. The operating parameters of the electric heating wire are set through the control panel of the storage component 4. The electric heating wire preheats the spray liquid in the storage tank to a suitable initial temperature, preparing it for the subsequent sterilization process. Then, the water pump 3 is started. The water pump 3 draws the preheated spray liquid from the storage component 4 through the connecting pipe and pressurizes and delivers it to the spray component 17 on the inner wall of the tank 2. Multiple spray nozzles on the spray component 17 spray the liquid as a mist. The sprayed liquid is sprayed out in a mist form. This mist-like spray has a larger surface area inside the tank 2, allowing for full contact with the heating environment and rapid, uniform sterilization. Simultaneously, the motor 5 is activated, driving the stirring shaft 18 to rotate within the tank 2, agitating the mist-like spray and ensuring uniform mixing to prevent uneven temperature distribution. By controlling the temperature within the tank 2 and the residence time of the spray, pasteurization is achieved, ensuring the elimination of harmful microorganisms while preserving as much of the effective components and quality as possible. The sterilized spray enters the filter tank 7 through the discharge pipe 11 at the lower end of the tank 2. At this point, the filter assembly 13 is installed inside the filter tank 7 under the action of the sliding seat 8. The limiting block 15, under the action of the first return spring 19, extends one end into the first limiting block groove 12, limiting and fixing the sliding seat 8 to ensure stable filtration of the spray by the filter assembly 13. As the spray passes through the filter assembly 13, impurities and particles are filtered out. The filtered pure spray liquid is discharged from the filter tank 7, completing the entire sterilization and filtration process. When the filter assembly 13 needs to be cleaned or replaced, pull the second pull rod 10 to drive the fixed slider 16 to slide inside the protective shell, so that the fixed slider 16 is separated from the limiting block 15. Then pull the first pull rod 9 to drive the limiting block 15 to slide in the second limiting block groove 14, so that the limiting block 15 is removed from the first limiting block groove 12. At this time, the filter assembly 13 can be removed from the filter tank 7 by sliding the sliding seat 8 on the filter tank 7.

[0036] After being sterilized in the filtration device, the spray liquid enters the filter tank 7 through the discharge pipe 11 at the lower end of the tank 2. At this time, the filter assembly 13 is installed in the filter tank 7 under the drive of the sliding seat 8. The limiting block 15 extends to the first limiting block groove 12 under the action of the first return spring 19, limiting and fixing the sliding seat 8 to ensure that the filter assembly 13 stably filters the spray liquid. When the spray liquid passes through the filter assembly 13, impurities and particles are filtered and intercepted. The filtered pure spray liquid is discharged from the filter tank 7, completing the entire sterilization and filtration process. This avoids the product from deteriorating during storage or use due to the presence of microorganisms that have not been completely killed, effectively improving the practicality and effectiveness of the equipment.
