A heating pipe is vertically installed at the center of the tank, with both ends passing through the tank and connecting to an external steam circulation pipe. When steam from the external steam pipe passes through the heating pipe, it heats the milk inside the tank, thus sterilizing the milk.

[0004] However, in the process of milk sterilization using related technologies, the contact between the milk and the heating element is relatively poor, which affects the heating effect of the milk and consequently the sterilization effect and efficiency, which needs to be improved. Utility Model Content

[0007] The sterilization tank is equipped with multiple heating tubes, which are arranged at equal intervals along the circumference of the sterilization tank. Each heating tube is curved, and the top of each heating tube is fixedly connected to the air inlet pipe and the bottom is fixedly connected to the exhaust pipe.

[0008] Optionally: the air intake pipe is rotatably connected to the sterilization tank and the corresponding connector via a first sealed bearing, the exhaust pipe is rotatably connected to the sterilization tank and the corresponding connector via a second sealed bearing, and the sterilization tank is provided with a drive mechanism for controlling the rotation of the air intake pipe.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 , Figure 2A milk sterilization device includes a sterilization tank 1. A feed pipe 2 is fixedly connected to the top of the sterilization tank 1, and a discharge pipe 3 is connected to the bottom. Control valves are respectively installed on the feed pipe 2 and the discharge pipe 3. Simultaneously, an air inlet pipe 4 is connected to the top of the sterilization tank 1, and an exhaust pipe 5 is connected to the bottom. The bottom of the air inlet pipe 4 and the top of the exhaust pipe 5 extend into the sterilization tank 1. Connectors 6 are respectively installed at the top of the air inlet pipe 4 and the bottom of the exhaust pipe 5, and the connectors 6 are used to connect to an external steam circulation pipe.

[0021] Reference Figure 1 , Figure 2 The sterilization tank 1 is internally equipped with multiple heating tubes 7, which are arranged at equal intervals along the circumference of the sterilization tank 1. Each heating tube 7 is curved, and its top is fixedly connected to an air inlet pipe 4, while its bottom is fixedly connected to an exhaust pipe 5. In this embodiment, if the inner diameter of the sterilization tank 1 is 1000 mm, the radial width of the heating tubes 7 along the sterilization tank 1 is approximately 400 mm, maximizing the contact area between the heating tubes 7 and the milk.

[0022] When hot steam enters the air inlet pipe 4 through the top connector 6, it enters multiple heating tubes 7 and heats them. At this time, the milk exchanges heat with the multiple heating tubes 7, thereby sterilizing the milk. Subsequently, the hot steam in the multiple heating tubes 7 enters the bottom connector 6 through the exhaust pipe 5 and is discharged into the external steam circulation pipe.

[0023] By setting multiple curved heating tubes 7, the contact opportunity between milk and heating tubes 7 is effectively increased, thereby improving the contact effect between milk and heating tubes 7, enhancing the uniformity of milk heating, and thus improving the sterilization effect and efficiency.

[0024] Reference Figure 1 , Figure 2 The air inlet pipe 4 is rotatably connected to the sterilization tank 1 and the corresponding connector 6 via a first sealed bearing 8, and the exhaust pipe 5 is rotatably connected to the sterilization tank 1 and the corresponding connector 6 via a second sealed bearing 9. A drive mechanism 10 for controlling the rotation of the air inlet pipe 4 is provided on the sterilization tank 1. Meanwhile, support frames 11 are fixedly connected to the top and bottom of the sterilization tank 1, and the two connectors 6 are fixedly connected to the corresponding support frames 11 to prevent the connectors 6 from rotating synchronously with the air inlet pipe 4 and the exhaust pipe 5.

[0025] The intake pipe 4 is controlled to rotate by the drive mechanism 10. At this time, the intake pipe 4 can drive multiple heating tubes 7 and exhaust pipe 5 to rotate synchronously. This design enables the heating tubes 7 to rotate, thereby achieving the effect of mixing and stirring the milk, further improving the uniformity of heating of the milk, and thus improving the sterilization effect.

[0026] Reference Figure 1 , Figure 2 The drive mechanism 10 includes a drive motor 101 fixed on the sterilization tank 1. A drive gear 102 is fixedly sleeved on the output shaft of the drive motor 101, and a driven gear 103 is fixedly sleeved on the air inlet pipe 4. The driven gear 103 meshes with the drive gear 102 so that the air inlet pipe 4 and other components can rotate smoothly.

[0027] Reference Figure 1 , Figure 2 Each heating tube 7 is fixedly connected with multiple stirring blades 12, and the multiple stirring blades 12 are arranged along the length of the heating tube 7, thereby improving the mixing and stirring effect of the milk. At the same time, the stirring blades 12 also have the ability to dissipate heat, thereby improving the heating effect of the milk.

[0028] Reference Figure 1 , Figure 2 Each stirring blade 12 has multiple stirring holes 13 that are arranged at equal intervals along the length of the stirring blade 12. When the stirring blade 12 moves, this design can break the movement pattern of the milk, improve the stirring effect, and thus improve the uniformity of the milk's heating.

[0029] Reference Figure 1 , Figure 2 An insulation sleeve 14 is provided on the sterilization tank 1 to improve the heat insulation and heat preservation effect of the sterilization tank 1, reduce the risk of heat loss, and improve energy utilization efficiency.
