In the production process of milk bars, pasteurization is a key link to ensure the safety of raw milk, prevent microbial contamination, and extend the shelf life of the product. The pasteurization device is a sterilization equipment used in the food processing industry, especially when processing milk and dairy products. Its core principle is to heat the liquid to a certain temperature and keep it for a period of time to reduce or eliminate pathogens and harmful microorganisms in it, while trying to retain the nutritional value and flavor of the food.

The milk is heated unevenly. After the heating is stopped, some of the milk may not reach the specified temperature, and the temperature of some of the milk may be too high, which reduces the disinfection effect. A plurality of heat conducting plates 33 are fixedly connected to the branch pipe 32. The heat conducting plates 33 transfer the heat in the high-temperature hot water to the low-temperature milk, thereby improving the heating efficiency. Three stirring shafts 34 are rotatably connected in the barrel body 1. A plurality of stirring blades 35 are fixedly connected to the stirring shaft 34. Rotating the three stirring shafts 34 allows the stirring blades 35 to stir the milk, thereby further improving the uniformity of heating.

[0029] Reference Figure 1-3The barrel body 1 is provided with a circulation structure 4, which is mainly composed of a first water pump 41. The output end of the first water pump 41 is fixedly connected to the hot water pipe 31. The input end of the first water pump 41 is fixedly connected to a first connecting pipe 42. The first connecting pipe 42 is fixedly connected to a second connecting pipe 44. One end of the second connecting pipe 44 is fixedly connected to a hot water tank 45. The second connecting pipe 44 is connected to the hot water tank 45 through a valve. A second liquid pump 46 is fixedly connected to the barrel body 1. The output end of the second liquid pump 46 is fixedly connected to a third connecting pipe 47. The third connecting pipe 47 is connected to the hot water tank 45 through a valve. The input end is connected to the hot water pipe 31, and a heating pipe 49 is fixedly connected to the hot water tank 45. The heating pipe 49 heats the water in the hot water tank 45, and then the valve on the second connecting pipe 44 is opened, and the first water pump 41 is started to pump the hot water in the hot water tank 45 to the hot water pipe 31 to heat the milk. When the water temperature of the hot water pipe 31 decreases, the valve on the third connecting pipe 47 is opened, and the second liquid pump 46 is started to pump the water in the hot water pipe 31 to the hot water tank 45 for reheating. This cycle can save water resources. A temperature sensor 412 is fixedly connected to the barrel body 1, and one end of the first connecting pipe 42 is fixedly connected to the cold water tank 43. The first connecting pipe 42 is connected to the cold water tank 43 through a valve, and the third connecting pipe 47 is fixedly connected to the fourth connecting pipe 48, which is connected to the cold water tank 43 through a valve. The temperature of the milk in the barrel 1 is measured by the temperature sensor 412. When the temperature reaches the required temperature, the signal is transmitted to the controller, and the controller turns off the first water pump 41, and starts the second liquid pump 46 to pump the hot water in the hot water pipe 31 to the hot water tank 45, and stops the fourth connecting pipe 48, so that the milk in the barrel 1 maintains the temperature for a certain period of time. The cold water tank 43 is fixedly connected to a semiconductor refrigeration chip 410, and the semiconductor refrigeration chip 410 A plurality of heat conducting plates 411 are fixedly connected thereto, one end of the heat conducting plate 411 is fixedly inserted in the hot water tank 45, the semiconductor refrigeration sheet 410 is started, the side of the semiconductor refrigeration sheet 410 away from the hot water tank 45 absorbs heat, and the side close to the hot water tank 45 releases heat and transfers it to the hot water tank 45 through the heat conducting plate 411, so the water temperature in the cold water tank 43 decreases, and the water temperature in the hot water tank 45 increases. After the milk in the barrel body 1 is kept at a certain temperature for a period of time, the valve on the first connecting pipe 42 is opened, and the first water pump 41 is started. The first water pump 41 pumps the low-temperature water in the cold water tank 43 into the hot water pipe 31 to cool the milk.

[0030] Working principle: milk is injected into the barrel 1 through the liquid inlet pipe 2, and then hot water is injected into the hot water pipe 31. The hot water will flow into the branch pipe 32, thereby exchanging heat with the milk to heat the milk. The branch pipes 32 increase the contact area with the milk and improve the heating uniformity, thereby avoiding the situation where the milk is heated unevenly, and some milk may not reach the specified temperature after the heating is stopped, and the temperature of some milk is too high, which leads to reduced disinfection effect. The heat conducting sheet 33 transfers the heat in the high-temperature hot water to the low-temperature milk, thereby improving the heating efficiency. The rotating three stirring shafts 34 can make the stirring blades 35 stir the milk, further improving the heating efficiency. The output shaft of the motor 311 drives a stirring blade 35 to rotate, and the rotation of the stirring blade 35 drives a first pulley 36 and a second pulley 38 to rotate. Under the action of the first transmission belt 37 and the second transmission belt 39, the two first pulleys 36 and the two second pulleys 38 rotate synchronously, thereby making the three stirring blades 35 rotate synchronously, making the operation more convenient and saving energy. The rock wool board 313 can improve the thermal insulation performance of the barrel body 1 and prevent the heat loss in the barrel body 1. The heating pipe 49 heats the water in the hot water tank 45, and then the valve on the second connecting pipe 44 is opened to start the first The water pump 41 pumps the hot water in the hot water tank 45 to the hot water pipe 31 to heat the milk. When the water temperature of the hot water pipe 31 drops, the valve on the third connecting pipe 47 is opened, and the second liquid pump 46 is started to pump the water in the hot water pipe 31 to the hot water tank 45 for reheating. This cycle can save water resources. The temperature of the milk in the barrel 1 is measured by the temperature sensor 412 (the model of the temperature sensor 412 is BL-RTD-3537, which is an existing product, so it is not described in detail here). When the temperature reaches the requirement, the signal is transmitted to the controller, and the controller turns off the first water pump 41 and starts the second liquid pump 46 to pump the hot water in the hot water pipe 31 to the hot water tank 45. The milk in the barrel 1 is kept at this temperature for a certain period of time, and the semiconductor refrigeration sheet 410 is started. The side of the semiconductor refrigeration sheet 410 away from the hot water tank 45 absorbs heat, and the side close to the hot water tank 45 releases heat and transfers it to the hot water tank 45 through the heat conduction plate 411. Therefore, the water temperature in the cold water tank 43 decreases, and the water temperature in the hot water tank 45 increases. After the milk in the barrel 1 is kept at a certain temperature for a period of time, the valve on the first connecting pipe 42 is opened, and the first water pump 41 is started. The first water pump 41 pumps the low-temperature water in the cold water tank 43 into the hot water pipe 31 to cool the milk.
