[0032] Further, the stirring assembly further comprises stirring rods 7 arranged on the outer circumference of the stirring rod 4 at intervals with the connecting ring 6, and the stirring blades 8 are fixedly arranged at the end of the stirring rod 7 away from the stirring rod 4.

[0033] Further, the stirring rods 7 are arranged in at least two groups along the length direction of the stirring rod 4, and each group of stirring rods 7 is arranged in at least two along the circumferential direction of the outer wall of the stirring rod 4.

[0034] Further, the motor 9 is fixedly arranged on the upper end surface of the cover 3, the power output shaft of the motor 9 penetrates the lower end surface of the cover 3 and is fixedly connected with the upper end of the stirring rod 4.

[0035] Further, the liquid inlet pipe 10 is arranged on the upper end surface of the cover 3 at intervals with the motor 9, and the liquid inlet pipe 10 is in communication with the inner cavity of the inner container 1.

[0036] Further, the liquid outlet pipe 11 is arranged at the lower end of the inner container 1, and the liquid outlet pipe 11 is in communication with the inner cavity of the inner container 1.

[0037] Further, the outer shell 12 is fixedly sleeved outside the inner container 1, and the annular space for accommodating the electric heating pipe 2 is formed between the outer shell 12 and the inner container 1.

[0038] The inner layer of the outer shell 12 is a heat insulation layer.

[0039] Further, the inner container 1 is made of food-grade stainless steel or food-grade aluminum alloy.

[0040] The working principle of the above technical scheme is as follows:

[0041] The fresh milk pasteurization device can be used for pasteurization of fresh milk and liquid food such as fruit juice. In order to prevent the fresh milk or fruit juice from adhering to the inner wall of the inner container 1 during the pasteurization process and affecting the heat transfer effect, the connecting ring 6 is fixedly arranged on the upper and lower parts of the stirring rod 4, and the scraper 5 is arranged between the connecting rings 6. The shape of the outer wall of the scraper 5 is adapted to the shape of the inner container 1. During the rotation of the scraper 5, the outer wall of the scraper 5 contacts the side wall of the inner container 1 and stirs the liquid food in the inner container 1, which can prevent the liquid food from adhering to the inner wall of the inner container 1. Because the stirring assembly is used in the fresh milk pasteurization device, the liquid food in the inner container 1 can flow continuously, which improves the heat transfer efficiency, so the temperature of the electric heating pipe can be controlled between 100-140 degrees. Compared with hot water or steam heating, the heating time can be shortened and the sterilization efficiency can be improved.

[0042] The fresh milk pasteurization equipment includes an inner tank with heating elements 2 fixedly mounted on its outer circumference. The heating elements 2 are arranged in a spiral pattern. A cover 3 is detachably connected to the top of the inner tank 1. The cover 3 is connected to a flange on the upper surface of the inner tank 1 by bolts. A sealing gasket can be installed between the cover 3 and the inner tank. The sealing gasket is made of food-grade material, such as food-grade polytetrafluoroethylene. A motor 9 and an inlet pipe 10 are spaced apart on the upper part of the cover 3. An outlet pipe 11 is installed at the lower end of the inner tank 1. Both the inlet pipe 10 and the outlet pipe 11 communicate with the inner cavity of the inner tank 1 for injecting and discharging fresh milk. Valves can be detachably connected to both the inlet pipe 10 and the outlet pipe 11. The inner tank 1 can be made of food-grade stainless steel or food-grade aluminum alloy.

[0043] When fresh milk is injected into the inner tank 1 through the inlet pipe 10, the heating element 2 is energized. The heat from the heating element 2 heats the fresh milk through the side wall of the inner tank 1. A temperature sensor is installed inside the inner tank 1 or on the lower end face of the cover 3 to detect the internal temperature of the fresh milk. The internal temperature of the fresh milk is brought to the pasteurization temperature range and maintained for a corresponding time. Then, the fresh milk is released through the outlet pipe 11. By controlling the heating temperature of the heating element 2 and the flow rate of the fresh milk, pasteurization of the fresh milk can be carried out continuously. The wire of the heating element 2 is connected to the heating element 2 through the hole set on the outer shell 12. The upper and lower ends of the outer shell 12 are fixedly connected to the upper and lower ends of the inner tank 1, respectively. The connection can be made by welding or by bolting, which facilitates the disassembly of the outer shell 12 and the inner tank 1 for maintenance of the heating element.

[0044] The stirring assembly includes a stirring rod 4 fixedly connected to the power output shaft of a motor 9. Connecting rings 6 are fixedly mounted on the upper and lower parts of the stirring rod 4, respectively. The connecting rings 6 can be connected via... Figure 5 The spokes shown are connected to the stirring rod 4. The stirring rod 4 and the connecting ring 6 are coaxially arranged to improve the stability of rotation. At least two sets of stirring rods 7 are fixedly arranged between the two connecting rings 6 on the outer circumference of the stirring rod 4 along the length of the stirring rod 4. At least two stirring rods 7 are arranged in an array along the circumferential direction of the outer wall of the stirring rod 4. Stirring blades 8 are fixedly arranged at the end of the stirring rod 7 away from the stirring rod 4 to stir the fresh milk during the heating process, improve the heat transfer efficiency, and make the fresh milk heat evenly.

[0045] The inner layer of the outer shell 12 is a heat insulation layer, which can be made of polyurethane. The outer layer of the outer shell 12 serves as a protective and supportive layer, which can be made of stainless steel. Three support legs 13 arranged in a circular array are fixed at the bottom of the outer shell 12 to support the entire fresh milk pasteurization equipment. Flanges can be installed at the lower end of the support legs 13 to fix the support legs 13 to the ground with bolts.

[0046] The beneficial effects of the above technical solution are as follows:

[0047] The fresh milk pasteurization equipment, the stirring assembly on the lower end face of the cover body is located in the inner container, the arc-shaped scraper fixedly arranged on the stirring rod scrapes the fresh milk on the inner wall of the inner container when the stirring rod rotates, prevents the fresh milk from adhering to the inner wall of the inner container and affecting heat transfer of the inner container, and improves sterilization efficiency and sterilization effect.
