Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a high-pressure homogenizing device for dairy products. Background Technology

[0002] High-pressure homogenizers are key equipment in dairy processing. If the large amount of heat generated during operation is not dissipated in a timely manner, it will seriously affect the equipment's lifespan and operational stability. To address this issue, existing technologies, such as the patent application number CN202223159960.1, propose a high-pressure homogenizer for fresh milk. This homogenizer incorporates circulating cooling water pipes outside the heat dissipation tanks of its main body, supplemented by a cooling fan, aiming to enhance heat exchange through forced air cooling.

[0003] However, this solution has fundamental flaws: First, its heat exchange path relies on a conduction chain of "heat sink → air → cooling water pipes." Air, being a poor conductor of heat, creates significant thermal resistance during heat transfer from the heat sink to the cooling water pipes, resulting in extremely low overall heat exchange efficiency. Second, the fan aims to quickly dissipate hot air, while the cooling water pipes require slow airflow to fully absorb heat. These two objectives conflict, meaning that heat cannot be effectively absorbed by the water pipes during rapid airflow, thus weakening the overall cooling effect. More seriously, exposed pipes, cooling tanks, and other components are highly susceptible to dust accumulation and bacterial growth, posing a serious food safety hazard and failing to meet the stringent hygiene requirements of modern food production.

[0004] Therefore, how to design a homogenizer cooling structure that can achieve efficient direct heat conduction and fully meet food-grade hygiene and safety requirements is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a high-pressure homogenizing device for dairy products, so as to solve the problems of low heat exchange efficiency caused by the use of external indirect heat exchange method in the prior art, and food safety hazards caused by the non-closed system.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure homogenizing device for dairy products includes a homogenizer body and a heat dissipation tank disposed on the homogenizer body. Crucially, it also includes heat exchange pipelines, a micro-pump, and a heat dissipation unit. The homogenizer body is divided into a hot zone and a cooling zone. The heat dissipation tank and the micro-pump are disposed in the hot zone, with the micro-pump driving the coolant circulation. The heat exchange pipelines are disposed on the inner wall of the heat dissipation tank and are tightly fitted to the inner wall. The heat dissipation unit is disposed in the cooling zone and is used to cool the coolant after it has absorbed heat. The heat exchange pipelines, the micro-pump, and the heat dissipation unit are connected by pipelines to form a completely closed coolant circulation system.

[0008] As a further embodiment of this utility model, the inner wall of the heat dissipation groove is provided with a groove that is compatible with the heat exchange pipeline, and the heat exchange pipeline is embedded in the groove and fixedly connected to the inner wall of the heat dissipation groove by brazing.

[0009] As a further embodiment of this utility model, the heat dissipation unit includes a radiator and an axial fan, the inlet of the radiator is connected to the outlet of the micro pump, and the axial fan is disposed on one side of the radiator.

[0010] As a further embodiment of this invention, the closed coolant circulation system is filled with a food-grade propylene glycol aqueous solution.

[0011] As a further embodiment of this utility model, the inner wall of the heat dissipation groove is also fixedly connected with a number of heat-conducting fins, which are in contact with or adjacent to the heat exchange pipeline.

[0012] As a further embodiment of this invention, the micro pump is a magnetically driven pump and is fixed to the internal base plate of the homogenizer body by a shock-absorbing bracket.

[0013] By adopting the above technical solution, this utility model will have the following beneficial effects:

[0014] By tightly fitting the heat exchange pipes to the inner wall of the heat dissipation tank, direct and efficient heat transfer from the shell to the coolant is achieved, resulting in a short heat exchange path and low resistance. The entire system employs a completely closed-loop design, with the coolant circulating internally, eliminating external contamination and ensuring the hygiene and safety of food processing. The interior of the device is clearly divided into hot and cooling zones, achieving physical isolation between heat absorption and dissipation processes, preventing interference and optimizing the heat dissipation path. A micro-pump provides stable power for coolant circulation, ensuring continuous heat transfer. Meanwhile, the heat dissipation unit located in the cooling zone provides concentrated and efficient cooling of the heat-carrying coolant.

[0015] Compared with existing technologies, this utility model has a compact structure, significantly improved heat dissipation efficiency, and meets the stringent requirements for hygiene and safety in food production, effectively ensuring the long-term stable operation of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 In one embodiment of the high-pressure homogenizing device for dairy products provided by this utility model, the high-pressure homogenizing device for dairy products includes a homogenizer body 1 and a heat dissipation tank 2. The homogenizer body 1 is divided into a hot zone 11 and a cooling zone 12. The heat dissipation tank 2 and the main heat-generating components of the homogenizer are both located in the hot zone 11. The cooling zone 12 is a ventilation compartment at the rear of the homogenizer body 1, which is isolated from the hot zone 11 to ensure a relatively independent working environment.

[0024] The core innovation of this embodiment lies in the integration of a highly efficient and hygienic built-in heat exchange system, which completely solves the problems of low efficiency and high hygiene risks associated with external cooling devices. The system mainly includes: heat exchange piping 3, a micro pump 4, and a heat dissipation unit 5. These three components are connected by piping to form a completely closed coolant circulation system. All key components are located inside the homogenizer body 1, eliminating contact with the external environment.

[0025] Specifically, the structure and function of each component are as follows:

[0026] The heat exchange pipe 3 is the core of heat absorption. It is made of food-grade 316L stainless steel and integrally bent into a serpentine coil. To achieve the most efficient heat conduction, the inner wall of the heat dissipation groove 2 is pre-machined with a semi-circular groove matching the outer diameter of the pipe. The heat exchange pipe 3 is embedded in this groove and permanently metallurgically bonded to the inner wall of the heat dissipation groove 2 using a high-frequency brazing process. This built-in, fitted design enables direct metal-to-metal conduction from the homogeneous casing to the coolant, resulting in extremely low thermal resistance and efficiency far exceeding that of external air cooling.

[0027] As a further optimization, several copper heat-conducting fins 21 are fixedly connected to the inner wall of the heat dissipation groove 2. These heat-conducting fins 21 are arranged in parallel in the gaps of the heat exchange pipe 3, in contact with or adjacent to the heat exchange pipe 3, and act as thermal bridges to quickly transfer heat from the shell to the heat exchange pipe 3, thereby further improving the heat absorption efficiency.

[0028] The heat dissipation unit 5 is the core of heat release. It is located in the cooling zone 12 of the homogenizer body 1 and includes a radiator 51 and an axial fan 52. The radiator 51 is an aluminum plate-fin structure, and its internal flow channel inlet is connected to the outlet of the micro pump 4; the axial fan 52 is installed on the outside of the radiator 51.

[0029] After the axial fan 52 starts, it forces in cool external air through the air inlet on the rear casing of the homogenizer body 1. This cool air does not come from the high-temperature area inside the homogenizer, but from the constant-temperature workshop environment. The cool air is blown directly and at high speed by the axial fan 52 over the fins of the radiator 51, where it undergoes efficient heat exchange with the high-temperature coolant in the pipes. The air that has absorbed heat is then forced out of the rear casing of the homogenizer body 1 by the exhaust fan 6 at the upper exhaust port, forming an independent and efficient convection airflow channel. This ensures that the radiator 51 is always exchanging heat with fresh cool air, rather than idling in the stuffy air inside the machine.

[0030] The micro pump 4 is the power source of the circulation system, preferably a magnetically driven centrifugal pump, whose design without dynamic seals fundamentally eliminates the risk of leakage. It is located in the hot zone 11 and fixed to the bottom plate inside the homogenizer body 1 by a shock-absorbing bracket 41, away from the main vibration source, to ensure stable operation.

[0031] It should be noted that the entire closed-loop system is filled with food-grade propylene glycol aqueous solution, which is non-toxic, non-corrosive, and fully meets the hygiene and safety requirements for food processing.

[0032] The complete workflow of this utility model is as follows:

[0033] When the homogenizer starts, the micro pump 4 and the axial fan 52 operate synchronously. The heat generated by the homogenizer is efficiently absorbed by the coolant in the heat exchange pipe 3 through direct conduction and with the assistance of the heat-conducting fins 21, via the inner wall of the heat dissipation slot 2. The coolant, after absorbing heat, is pumped by the micro pump 4 to the rear heat dissipation unit 5. In the dedicated air duct of the heat dissipation unit 5, external cold air forced in by the axial fan 52 flows through the radiator 51, efficiently carrying away the heat from the coolant and expelling it outside the machine through the exhaust fan 6. The cooled coolant then flows back to the heat exchange pipe 3, starting a new round of heat absorption cycle. In this way, this invention achieves continuous, efficient, and hygienic cooling of the core components of the homogenizer.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
