Description

Technical Field

[0001] The utility model relates to the field of milk product sterilization, in particular to a milk product sterilization device. Background Art

[0002] Dairy products are rich in nutrients, such as protein, fat and sugar, which can easily become a breeding ground for microbial growth and reproduction. If not sterilized, microorganisms in dairy products, including Escherichia coli, Staphylococcus aureus and zoonotic pathogens such as Brucella and Mycobacterium tuberculosis, may grow rapidly, causing food spoilage and even spreading diseases. Therefore, sterilization is an indispensable step in the processing of dairy products.

[0003] The working principle of ultra-high temperature instantaneous pasteurization is to heat the food to a high temperature of 135-150℃, maintain it for 3-6 seconds, and then quickly cool it to kill microorganisms while trying to maintain the original flavor and quality of the dairy products.

[0004] Current ultra-high temperature instantaneous sterilization devices mostly use heat pipes to heat the medium in the tank body. The feed pipe is set in the medium, and then the milk products are heated by heat exchange between the medium and the feed pipe. This heat exchange method requires relatively large energy, and the temperature of the medium in the tank body is affected by the heat pipe. It is often the case that the temperature of the medium far away from the heat pipe is low, and the temperature of the medium close to the heat pipe is high, resulting in poor sterilization effect and easily affecting the quality of dairy products. Utility Model Content

[0005] The utility model is based on the above technical problems and proposes a milk product sterilization device.

[0006] A milk product sterilization device comprises: a hot tank, a cold tank, a flow pipe, a heat pipe and a cold pipe, wherein the flow pipe enters into the hot tank from the upper part of the hot tank, then enters into the cold tank from the lower part of the hot tank, and finally extends outward from the lower part of the cold tank; the heat pipe is arranged inside the hot tank, the cold pipe is arranged inside the cold tank, the flow pipe passes through the inside of the hot pipe and the cold pipe, the upper part of the heat pipe and the lower part of the heat pipe are provided with a heat supply pipe and a heat return pipe respectively connected to a heater, and the upper part of the heat pipe and the lower part of the heat pipe are provided with a cold liquid pipe and a return liquid pipe respectively connected to a refrigerator.

[0007] Preferably, the flow pipe meanders downward in the hot tank and the cold tank.

[0008] Preferably, the hot tank and the cold tank are also connected to a vacuum pump via a negative pressure pipe.

[0009] Preferably, a heat insulation layer is provided on the outer walls of the cold pipe and the hot pipe.

[0010] Beneficial effects: The device allows the flow tube to flow through the hot pipe and the cold pipe, a heating medium flows in the hot pipe, and a cooling medium flows in the cold pipe. In this way, when the liquid dairy product flows through the hot pipe, it will be quickly heated by the heating medium, and then enter the cold pipe for rapid cooling. In this process, the medium flows in the hot pipe and the cold pipe, and is recycled by the heater and the refrigerator, which can greatly reduce energy consumption, and the circulation process is faster, the temperature difference between the upper and lower media is small, and the sterilization effect and taste of the dairy products can also be guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 The utility model is shown in the structural diagram. DETAILED DESCRIPTION

[0012] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0013] like Figure 1 The milk product sterilization device shown comprises: a hot tank 1, a cold tank 2, a flow tube 3, a heat tube 4, and a cold tube 10. The flow tube 3 enters the hot tank 1 from the upper part of the hot tank 1, then enters the cold tank 2 from the lower part of the hot tank 1 to the upper part of the cold tank 2, and finally extends outward from the lower part of the cold tank 2. The flow tube 3 bends downward in the hot tank 1 and the cold tank 2, the front part of the flow tube 3 is a feed tube 5, and the tail part of the flow tube 3 is a discharge tube 6.

[0014] The upper part of the flow tube 3 is fed into the hot tank 1 through the feed pipe 5. The heat pipe 4 is arranged inside the hot tank 1. The heat pipe 4 is arranged outside the flow tube 3. There is a heating medium in the heat pipe 4. The heating medium enters the heat pipe 4 from the heating pipe 8 of the heater, and returns to the heater from the heat return pipe 9 for reheating after circulating in the heat pipe 4. In order to reduce the heat dissipation of the heating medium from the heat pipe 4 to the outside, an insulation layer 7 can be arranged on the outer wall of the heat pipe 4. Similarly, an insulation layer 7 is also arranged on the outer wall of the cold pipe 10.

[0015] The cold pipe 10 is arranged inside the cold tank 2. The dairy products in the flow tube 3 are quickly heated by the heat pipe 4 and then enter the cold pipe 10. A cold liquid pipe 11 and a return liquid pipe 12 are arranged at both ends of the cold pipe 10. The cold pipe 10 is connected to the refrigerator through the cold liquid pipe 11 and the return liquid pipe 12. The refrigerant in the cold pipe 10 will quickly exchange heat with the high-temperature dairy products to reduce the temperature of the dairy products, and then enter the temporary storage tank from the discharge pipe 6 at the bottom of the cold tank 2.

[0016] In order to reduce the heat dissipation of the medium in the heat pipe 4 and the cold pipe 10, a negative pressure pipe 13 can be provided on the hot tank 1 and the cold tank 2, and connected to the vacuum device through the negative pressure pipe 13.
