Description

Technical Field

[0001] This utility model relates to the field of milk production technology, specifically to an anti-overflow pasteurization machine for milk production. Background Technology

[0002] Pasteurization, also known as low-temperature sterilization, is a cold sterilization method invented by the French microbiologist Louis Pasteur. It is a sterilization method that uses relatively low temperatures to kill pathogens while preserving the nutrients and flavor of the materials. The specific process involves heating the raw materials to be sterilized to 68–70°C, maintaining this temperature for 30 minutes, and then rapidly cooling them to 4–5°C. Since the lethal point for most bacteria is below 68°C and 30 minutes, this method kills both pathogenic and most non-pathogenic bacteria. The sudden cooling after heating also contributes to bacterial death due to the rapid temperature change.

[0003] However, when using existing technology to pasteurize milk, water in the pasteurization tank and cooling tank easily overflows as the milk is transported by the conveyor belt. Since the overflowing water is not recycled, it needs to be cleaned up by the staff, which indirectly increases the workload of the staff. At the same time, it is not possible to promptly input the required hot and cold water into the pasteurization tank and cooling tank, which affects the pasteurization and cooling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an anti-overflow pasteurization machine for milk production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An overflow-proof pasteurization machine for milk production includes a frame, a conveyor fixedly connected to the inner side of the frame, a conveyor belt drivenly connected to the inner side of the conveyor, a pasteurization tank and a cooling tank fixedly connected to the inner side of the frame, a pasteurization chamber fixedly connected to the top of the frame, collection boxes fixedly connected to both sides of the pasteurization tank and the cooling tank, a recovery pipe fixedly connected to the bottom of the collection boxes, a recovery box fixedly connected to the bottom of the pasteurization tank and the cooling tank, a spare water tank fixedly connected to each corresponding surface of the pasteurization tank and the cooling tank, a water supply pipe fixedly connected to one side of the spare water tank, a water supply electric valve rotatably connected to the surface of the water supply pipe, and a water outlet pipe fixedly connected to the bottom of the spare water tank, with a water outlet electric valve rotatably connected to the surface of the water outlet pipe.

[0007] Preferably, overflow holes are provided on both sides of the sterilization tank and the cooling tank, and the overflow holes are fixedly connected through and extend into the collection box.

[0008] Preferably, the recycling box is fixedly connected to one end of the recycling tube on both sides, and a connecting tube is fixedly connected to the bottom of the recycling box.

[0009] Preferably, both the sterilization tank and the cooling tank are made of transparent material.

[0010] Preferably, the conveyor belt surface has multiple holes, and multiple clamps are fixedly connected to the conveyor belt surface.

[0011] Preferably, the sterilization box is equipped with baffles made of flexible and high-temperature resistant material at the material input end near the sterilization tank and at the material output end near the sterilization tank.

[0012] Preferably, the conveyor, the water supply valve, and the water outlet valve are all electrically connected to the external control panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, the milk to be sterilized is placed in a container, which is then placed between clamps to secure it. The container is then placed at one end of a conveyor belt, which rotates, moving the container until it reaches the sterilization tank. As more containers move, water overflows from the tank. To prevent this from spilling directly to the outside and increasing the workload, water overflows through an overflow hole into a collection box, which is then collected by a recycling pipe at the bottom. The bottom of the collection box is connected to an external storage device to receive the overflowing water. As water overflows into the collection box, the water level in the sterilization tank decreases. If not replenished promptly, this can affect the sterilization effect. Therefore, after observing a certain amount of overflow, the water outlet valve connected to the sterilization tank is activated via the external control panel. The outlet pipe then delivers hot water from a backup water tank to the sterilization tank to replenish the overflowing water. After sterilization, the container moves to a cooling tank under the action of the conveyor belt for cooling. The cooling process for the overflowing water follows the same principle as the sterilization tank and will not be elaborated further. Attached Figure Description

[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. 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.

[0021] Please see Figure 1-4This utility model provides a technical solution: an anti-overflow pasteurization machine for milk production, comprising a frame 1, a conveyor 2 fixedly connected to the inner side of the frame 1, a conveyor belt 3 drivingly connected to the inner side of the conveyor 2, a pasteurization tank 5 and a cooling tank 12 fixedly connected to the inner side of the frame 1 respectively, a pasteurization box 4 fixedly connected to the top of the frame 1, collection boxes 6 fixedly connected to both sides of the pasteurization tank 5 and the cooling tank 12 respectively, overflow holes are provided on both sides of the pasteurization tank 5 and the cooling tank 12 respectively, the overflow holes are fixedly penetrated and extended into the collection box 6, a recovery pipe 7 is fixedly connected to the bottom of the collection box 6, a recovery box 8 is fixedly connected to the bottom of the pasteurization tank 5 and the cooling tank 12, and a spare water tank 9 is fixedly connected to the corresponding surface of the pasteurization tank 5 and the cooling tank 12 respectively, with a water supply pipe fixedly connected to one side of the spare water tank 9. Pipe 10, with a water supply valve 11 rotatably connected to its surface; a water outlet pipe 14 is fixedly connected to the bottom of the spare water tank 9, with a water outlet valve 15 rotatably connected to its surface; the conveyor 2, water supply valve 11, and water outlet valve 15 are all electrically connected to the external control panel; the recycling box 8 is fixedly connected to one end of the recycling pipe 7 on both sides, and a connecting pipe 13 is fixedly connected to the bottom of the recycling box 8; the sterilization tank 5 and cooling tank 12 are both made of transparent material; the conveyor belt 3 has multiple holes on its surface, and multiple clamps 16 are fixedly connected to its surface; the sterilization box 4 has baffles made of flexible and high-temperature resistant material suspended at the material input end near the sterilization tank 5 and at the material output end near the sterilization tank 5 (the holes, baffles, and control panel are not the main design features, so...). (Not shown in the diagram) Hot water meeting sterilization requirements and cold water meeting combined cooling requirements are pre-filled into sterilization tank 5 and cooling tank 12. The baffle of sterilization tank 4 can reduce heat loss in sterilization tank 5 without affecting container transport. Then, the conveyor 2 and water supply valve 11 are started through the external control panel. The water supply valve opens, and water supply pipe 10 transports hot water meeting sterilization requirements from the heater connected to the outside to the standby water tank 9 connected to sterilization tank 5, and cold water meeting cooling requirements from the cooler connected to the outside to the standby water tank 9 connected to cooling tank 12 (the heater and cooler are existing technologies and will not be described in detail). The milk to be sterilized is placed into the container, and then the container is placed between the clamps 16 to clamp the container. Then, the container is placed at one end of the conveyor belt 3. The conveyor 2 drives the conveyor belt 3 to rotate, thereby moving the container until it enters the sterilization tank 5. As more and more containers move, water in the sterilization tank 5 will overflow. To prevent direct overflow to the outside and increase the workload of the staff, when water overflows, it overflows into the collection box 6 through the overflow hole, and then is collected into the collection box 8 through the recovery pipe 7 at the bottom of the collection box 6. The connecting pipe 13 at the bottom of the collection box 8 is connected to an external storage device to receive the overflowing water. When water overflows into the collection box 6, the water in the sterilization tank 5 will decrease. If it is not added in time, it will easily affect the sterilization effect. Therefore, after observing that a certain amount of water has overflowed, the water outlet valve 15 connected to the sterilization tank 5 is activated through the external control panel.The outlet pipe 14 transports hot water from the spare water tank 9 to the sterilization tank 5 to replenish the overflowing water. After sterilization, the container moves to the cooling tank 12 under the action of the conveyor belt 3 for cooling. The cooling process for the overflowing water is the same as that of the sterilization tank 5, and will not be described further. The container continues until it reaches the other end of the conveyor belt 2, at which point it is removed from the surface of the conveyor belt 3.

[0022] Working principle: When in use, hot water that meets the sterilization requirements and cold water that meets the composite cooling requirements are pre-filled into the sterilization tank 5 and the cooling tank 12. The baffle of the sterilization box 4 can reduce the heat loss in the sterilization tank 5, but will not affect the transport of containers.

[0023] Then, the conveyor 2 and the water supply valve 11 are started through the external control panel. The water supply valve is opened, and the water supply pipe 10 delivers the hot water that meets the sterilization requirements in the heater connected to the outside to the spare water tank 9 connected to the sterilization tank 5, and delivers the cold water that meets the cooling requirements in the cold zone connected to the outside to the spare water tank 9 connected to the cooling tank 12.

[0024] The milk to be sterilized is placed into a container, which is then placed between clamps 16 to clamp it. The container is then placed at one end of conveyor belt 3. Conveyor 2 drives conveyor belt 3 to rotate, thus moving the container until it enters sterilization tank 5. As more and more containers move, water in sterilization tank 5 will overflow. To prevent direct overflow and increased workload for staff, overflowing water is channeled through overflow holes into collection box 6, and then collected into collection box 8 through recycling pipe 7 at the bottom of collection box 6. The connecting pipe 13 at the bottom of collection box 8 connects to an external storage device to receive overflow. When water overflows into the collection box 6, the water in the sterilization tank 5 will decrease. If it is not added in time, it will easily affect the sterilization effect. Therefore, after observing that a certain amount of water has overflowed, the water outlet valve 15 connected to the sterilization tank 5 is activated through the external control panel. The water outlet pipe 14 then transports the hot water in the spare water tank 9 to the sterilization tank 5 to replenish the overflowing water. After sterilization, the container moves to the cooling tank 12 under the action of the conveyor belt 3 for cooling. The principle of cooling the overflowing water is the same as that of the sterilization tank 5, so it will not be described again. The container moves to the other end of the conveyor 2 and is then removed from the surface of the conveyor belt 3.

[0025] The above steps allow for the recovery of spilled water and timely replenishment.
