Description

Technical Field

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

[0002] Milk, goat milk and other dairy products are rich in nutrients. High temperature sterilization will destroy their nutrients. If the high temperature is maintained for too long, the nutrients will be destroyed and even produce substances that are harmful to human health. Therefore, when high temperature sterilization is performed on milk, goat milk and other dairy products, the heating speed must be fast so that they can quickly reach the sterilization temperature, and then the temperature must be quickly lowered when the sterilization time is reached to maximize the retention of nutrients.

[0003] The existing Chinese patent CN214509155U discloses a high-temperature sterilization device for dairy products. After the sterilization temperature and time set by the controller, the heat dissipation valve will automatically open, and the sterilized dairy products will flow into the heat dissipation pipe. The water pump will pump the water in the water tank to the heat dissipation cavity, and the water will then return to the water tank from the heat dissipation cavity through the water outlet pipe, driving the water flow, and the water flow will take away the heat on the heat dissipation pipe to achieve the purpose of heat dissipation, so as to retain its nutrients to the maximum extent.

[0004] However, after the heat dissipation valve of the above-mentioned high-temperature sterilization device for dairy products is opened, although dairy products can flow into the heat dissipation pipe, it still takes a long time for the dairy products on the top layer in the sterilization chamber to enter the heat dissipation pipe, and rapid cooling of all dairy products cannot be achieved. Utility Model Content

[0005] The purpose of the utility model is to provide a dairy product sterilizing device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dairy product sterilization device, comprising a sterilization box, wherein a heat-insulating layered plate is fixedly installed inside the sterilization box, wherein the heat-insulating layered plate divides the interior of the sterilization box into a sterilization chamber and a cooling chamber, and a dairy product flow mechanism is arranged inside the sterilization box;

[0007] The dairy product flow mechanism includes a heating section pipeline, a cooling section pipeline, a peristaltic pump, and a preheating box. The preheating box is fixedly installed on the top of the sterilization box. A feed pipe is connected and arranged at the top of the preheating box. The heating section pipeline is arranged in the sterilization cavity, and the top end of the heating section pipeline is connected to the inside of the preheating box. The cooling section pipeline is arranged in the cooling cavity, and the top end of the cooling section pipeline is connected to the bottom end of the heating section pipeline. Both the heating section pipeline and the cooling section pipeline are continuously bent heat-conducting pipes. There are multiple heating section pipelines and cooling section pipelines, and they are equally spaced. The sterilization cavity is filled with hot water, and the cooling cavity is filled with cold water. The bottom end of the cooling section pipeline extends out of the cooling cavity. The liquid inlet end of the peristaltic pump is connected to the bottom end of the cooling section pipeline. The bottom of the peristaltic pump is fixedly installed with a mounting frame, and the mounting frame is fixedly installed on the outer wall of the sterilization box.

[0008] Further, a first heating pipe is fixedly installed inside the sterilization cavity, and temperature sensors are arranged in both the sterilization cavity and the cooling cavity.

[0009] Further, a water pump is arranged on the left side of the sterilization box. A water tank is fixedly installed on the left outer wall of the sterilization box. The water inlet end of the water pump is connected to the inside of the water tank through a pipeline. A refrigeration device is fixedly installed on the left outer wall of the sterilization box, and the heat exchange end of the refrigeration device extends into the water tank. The water outlet end of the water pump is connected to the cooling cavity through a pipeline.

[0010] Further, a connecting pipe is connected to the liquid outlet end of the peristaltic pump, and a filling head is connected and arranged at the bottom end of the connecting pipe.

[0011] Further, a heat exchange box is covered on the outer wall of the preheating box. The feed pipe extends out of the heat exchange box. A second heating pipe is fixedly installed inside the preheating box.

[0012] Further, a U-shaped pipe is connected and arranged on the right inner wall of the heat exchange box. The bottom end of the U-shaped pipe is connected to the inside of the cooling cavity. A one-way valve is arranged at the connection between the U-shaped pipe and the heat exchange box. The left inner wall of the heat exchange box is connected to the inside of the water tank through a pipeline.

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

[0014] Taking the peristaltic pump as the driving part, on the one hand, it is used to drive the flow of dairy products in the heating section pipeline and the cooling section pipeline, and on the other hand, it controls the flow rate of dairy products in the heating section pipeline and the cooling section pipeline. The heating section pipeline is heated by the hot water in the sterilization cavity, and then the dairy products are heated and sterilized. The cooling section pipeline is cooled by the cold water in the cooling cavity, and then the dairy products are cooled. Because the dairy products are always flowing, the problem that some dairy products can be cooled in time while some cannot be cooled in time can be avoided;

[0015] The water that has been heated after participating in heat exchange in the cooling cavity is passed into the heat exchange box through a U-shaped tube, and then the dairy products in the preheating box are preheated. A one-way valve is set to prevent the water in the heat exchange box from flowing back into the cooling cavity. Since the heat exchange box is connected to the water tank through a pipeline, the water participating in preheating in the heat exchange box can flow back into the water tank, realizing the recycling of heat.

The dairy product is preheated (not heated to the sterilization temperature) through the preheating box 505 to ensure that the dairy product can be quickly heated to the sterilization temperature in the sterilization chamber 3. Then the dairy product flows through the heating section pipe 501 and the cooling section pipe 502 in sequence. Among them, the peristaltic pump 503 is used as a driving part. On the one hand, it is used to drive the flow of the dairy product in the heating section pipe 501 and the cooling section pipe 502.

The left inner wall of the heat exchange box 6 is connected with the inside of the water tank 7 through a pipeline. The water that has been heated after heat exchange in the cooling cavity 4 is introduced into the heat exchange box 6 through the U-shaped pipe 14, and then the dairy products in the preheating box 505 are preheated. The one-way valve 15 is provided to prevent the water in the heat exchange box 6 from flowing back into the cooling cavity 4. Since the heat exchange box 6 is connected with the water tank 7 through a pipeline, the water participating in preheating in the heat exchange box 6 can flow back into the water tank 7, realizing the recycling of heat.

[0030] Working principle: When in use, the dairy products are introduced into the preheating box 505 through the feed pipe 506, and then enter the heating section pipe 501 and the cooling section pipe 502 from the preheating box 505. The peristaltic pump 503 is turned on to drive the flow of the dairy products in the heating section pipe 501 and the cooling section pipe 502. The hot water in the sterilization cavity 3 heats the heating section pipe 501, thereby heating and sterilizing the dairy products. The cold water in the cooling cavity 4 cools the cooling section pipe 502, thereby cooling the dairy products. Since the dairy products are flowing all the time, the problem that some dairy products can be cooled in time while some cannot be cooled in time can be avoided.
