Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and specifically relates to a tank cooling device for deacidifying hot pot beef tallow. Background Art

[0002] With the development of technology and society, equipment in various fields has been greatly developed. Beef tallow is a kind of food in our life and can be used to make hot pots, hot pot bases, dairy products, etc. When producing, in order to ensure the taste of beef tallow and prevent equipment from being corroded, it is necessary to carry out deacidification treatment on beef tallow. And when deacidifying beef tallow, it needs to be carried out in a deacidification tank. However, the deacidification of beef tallow needs to be carried out at high temperature. Therefore, in order to protect the equipment, a cooling device is often needed to cool the deacidification tank. So, a tank cooling device is required.

[0003] However, the existing tank cooling devices for deacidifying hot pot beef tallow have the following deficiencies:

[0004] The existing tank cooling devices use a compression refrigerating machine as the core cold source, and convey a low-temperature medium to the tank jacket or coil through a refrigerant pipeline to reduce the tank temperature. This system includes core components such as a compressor, a condenser, an expansion valve, and an evaporator. When operating, the compressor consumes a large amount of electric energy as a power source, and a high-power refrigeration unit needs to be configured, resulting in a synchronous increase in the installed capacity and operating energy consumption. And the single-layer tank structure design leads to the problem of low cooling efficiency. Due to the lack of a layered cooling structure, when the refrigerant exchanges heat with the materials in the tank, it is impossible to achieve precise step-by-step control according to the temperature gradient, and the cooling capacity is difficult to be evenly distributed, easily resulting in local overcooling or insufficient cooling, leading to a significant reduction in the overall cooling efficiency.

[0005] Therefore, we propose a tank cooling device for deacidifying hot pot beef tallow to facilitate solving the problems mentioned above. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In the present invention, through the coordinated operation of the graphene heat-conducting layer, the phase-change interlayer and the honeycomb heat-exchange component, a gradient cooling effect with high efficiency and energy conservation is achieved. In the initial stage of the tank cooling, the high-temperature beef tallow directly contacts the phase-change interlayer. The phase-change point of this phase-change interlayer is set at 60°C. The graphene heat-conducting layer cooperating with it, relying on its ultra-high thermal conductivity characteristics, transfers the heat of the tank out at an extremely fast speed. When the temperature of the tank reaches 60°C, the phase-change material in the interlayer will undergo a phase-change process, changing from a solid state to a liquid state. During this process, a large amount of heat is absorbed and stored. This heat storage method can effectively buffer the heat release, greatly reducing the load of the external refrigeration unit and lowering its operating frequency and intensity, achieving energy conservation at the source. The honeycomb heat-exchange component is also started synchronously. This component adopts a special honeycomb structure design, and its internal flow channels have a very large specific surface area, significantly increasing the contact area between the refrigerant and the heat, and improving the heat-exchange efficiency. During the circulating flow of the refrigerant in the honeycomb heat-exchange component, it fully absorbs the heat conducted from the phase-change interlayer and further reduces the temperature from 60°C to 40°C. The heat cooled by the honeycomb heat-exchange component is finally intensively dissipated through the external heat-dissipating fins. In this system, each component has a clear division of labor and close cooperation, forming a complete cooling system. Finally, it is intensively dissipated through the external heat-dissipating fins. Throughout the cooling process, there is no need for the participation of a traditional external compressor cooling unit. Through the coordinated work of the graphene heat-conducting layer, the phase-change interlayer, the honeycomb heat-exchange component and the heat-dissipating fins, gradient cooling of the tank is achieved. While ensuring the cooling effect of the tank, the system energy consumption is greatly reduced, having significant energy-saving and environmental protection advantages and application values.

[0026] 2. In the present invention, by configuring the spray component and the infrared thermal imager to form an intelligent control unit, precise control of the cooling process is achieved. The infrared thermal imager monitors the surface temperature of the tank in real time. When it detects that the temperature of the tank drops below 25°C, the control system automatically issues an instruction. First, the honeycomb heat-exchange component is closed to stop the refrigerant circulation to terminate the active cooling process. At the same time, the spray component is started to form a water film covering the surface of the tank by evenly spraying. The spray component uses normal-temperature water as the medium, and its temperature is close to the ambient temperature. It can not only maintain the stability of the surface temperature of the tank through the sensible heat exchange of water, but also avoid the problem of excessive cooling caused by low-temperature refrigerant, and can effectively prevent the solidification of beef tallow.

[0027] 3. In the present invention, an intelligent regulation unit is constructed by setting up a magnetic field control component and an infrared thermal imager to achieve local precise cooling of the tank body surface. First, magnetite nanoparticles are uniformly dispersed in the refrigerant to form a magnetic fluid working medium with magnetic response characteristics. The infrared thermal imager scans the tank body surface in real time to construct a high-precision temperature field distribution model. When a local high-temperature area with a temperature greater than 65°C is identified, the system automatically marks the coordinates of this area and triggers the magnetic field control component at the corresponding position to enhance the magnetic induction intensity. Based on the magnetophoresis effect of the magnetic fluid, the change in the magnetic field gradient will generate a directional driving force on the nanoparticles suspended therein, thereby regulating the flow velocity of the magnetic fluid in the local flow channel. Through this dynamic magnetic field control mechanism, intelligent distribution of the refrigerant flow rate in different areas of the tank body surface can be achieved. The magnetic fluid flow rate in the high-temperature area is increased due to the enhanced magnetic field, strengthening the local heat transfer efficiency, while the basic flow rate is maintained in the low-temperature area to avoid overcooling, ultimately forming precise cooling regulation.

[0041] Such as Figures 3 - 5 And Figure 8 And Figure 11As shown: A tank cooling device for deacidifying hot pot beef tallow, including a cooling tank main body 100, a honeycomb heat exchange component 200, a graphene heat conduction layer 103, a phase change interlayer 105, a honeycomb heat exchange component 200, and a group of heat dissipation fins 109. The honeycomb heat exchange component 200, the graphene heat conduction layer 103, the phase change interlayer 105, and the honeycomb heat exchange component 200 are all located inside the cooling tank main body 100, and the heat dissipation fins 109 are located outside the cooling tank main body 100;

[0042] Example 1, as Figure 4 Shown is a cross-sectional view of the cooling tank main body 100. The cooling tank main body 100 includes an inner tank 101, an outer shell 102, and a cover 108. An oil delivery port 110 and a cold air port 112 are fixedly connected to the top of the cover 108. The output ends of the oil delivery port 110 and the cold air port 112 are respectively connected to a beef tallow atomizer 111 and a cold air atomizer 113. The inner parts of the inner tank 101 and the outer shell 102 are divided into a cooling interlayer 106 and a hollow interlayer 107, as Figure 5 , Figure 7 and Figure 8 shown. The cooling interlayer 106 is used to install the honeycomb heat exchange component 200 and the spray component 300. The cover 108 is installed on the top of the outer shell 102 by bolts. The graphene heat conduction layer 103 is arranged on the inner wall of the inner tank 101. A group of spiral diversion grooves 104 are opened on the inner wall of the graphene heat conduction layer 103 for guiding the beef tallow and conducting the heat of the beef tallow. The phase change interlayer 105 is sleeved on the outer wall of the inner tank 101 and is inside the cooling interlayer 106 for accurate temperature control by energy storage and energy release;

[0043] As Figure 8 and Figure 9 shown: It is a structural diagram of the honeycomb heat exchange component 200 and the refrigerant cooling component 2100. The honeycomb heat exchange component 200 includes a honeycomb microchannel 201, which is sleeved on the outer wall of the phase change interlayer 106 for rapid cooling. The top and bottom of the honeycomb microchannel 201 are respectively connected to a liquid inlet pipe 202 and a liquid outlet pipe 203. The liquid inlet pipe 202 and the liquid outlet pipe 203 are both fixedly connected to the refrigerant cooling component 2100 for cooling the refrigerant fluid in the honeycomb microchannel 201. The refrigerant cooling component 2100 includes a bracket 2101. A condenser tube 2102 is fixedly inserted inside the bracket 2101, and the input end of the condenser tube 2102 is connected to the liquid outlet pipe 203. A group of heat dissipation fins 2103 are fixedly sleeved on the outer wall of the condenser tube 2102. Two heat dissipation fans 2104 are installed on the top of the bracket 2101. The output end of the condenser tube 2102 is fixedly connected to a liquid storage tank 2105. The output end of the liquid storage tank 2105 is fixedly connected to a first pump 2106. The output end of the first pump 2106 is fixedly connected to the liquid inlet pipe 202, and the first pump 2106 is electrically connected to the PLC control unit 1101;

[0044] A set of heat dissipation fins 109 is arranged on the outer surface of the outer shell 102, which is used to enhance the heat dissipation performance of the outer shell 102 and can deform according to the surface temperature of the tank body.

[0045] The effects achieved by the entire Embodiment 1 are as follows: High-temperature butter (90°C - 100°C) enters the interior of the tank body through the oil delivery port 110. First, the butter atomizer 111 breaks it into micron-sized droplets. The atomized butter forms a large specific surface area, significantly enhancing the heat exchange efficiency with the tank body wall. The atomized droplets flow downward along the spiral diversion groove 104 in a spiral trajectory. This diversion structure further improves the heat transfer rate by extending the flow path and enhancing the turbulent effect. The graphene heat conduction layer 103 on the inner side of the tank body wall quickly conducts the heat of the butter to the outer phase change interlayer 105 (set phase change point of 60°C) due to its ultra-high heat conductivity. When the temperature of the tank body drops to 60°C, the PLC control unit 1101 starts the first pump 2106 to extract the ethylene glycol solution refrigerant in the liquid storage tank 2105. The refrigerant is injected into the honeycomb microchannel 201 through the liquid inlet pipe 202. The micron-sized flow channel design of the honeycomb structure provides a large specific surface area, enabling the refrigerant to efficiently exchange heat with the tank body wall and gradually reducing the temperature from 60°C to 40°C. The heat-absorbed refrigerant flows into the condenser tube 2102 through the liquid outlet pipe 203. At this time, the cooling fan 2104 starts, and the heat dissipation on the surface of the condenser tube 2102 is accelerated through forced convection. The cooled refrigerant returns to the liquid storage tank 2105 through the return pipeline, forming a closed-loop system. The heat dissipation fins 109 outside the tank body are made of nickel-titanium alloy memory metal and can automatically adjust the unfolding angle according to the surface temperature of the tank body. When the temperature is higher than 45°C, the fins automatically unfold to the maximum heat dissipation area (unfolding angle ≥ 90°), and when the surface of the tank body is lower than 35°C, they fold and fit the tank body (folding angle ≤ 30°), effectively reducing the floor area of the system while ensuring the heat dissipation efficiency.

[0046] Embodiment 2, as Figure 7As shown: a spray assembly 300 is installed inside the cooling interlayer 106, and the spray assembly 300 includes a set of fixed lining plates 301, and a water pipe 302 is fixed on one side of the outer surface of each set of fixed lining plates 301, and each water pipe 302 is connected to each other, and an atomizing nozzle 303 is arranged on one side of the outer wall of each water pipe 302, and a water inlet end 304 is fixedly connected to the top of one water pipe 302, and a water outlet end 305 is fixedly connected to the bottom of the cooling interlayer 106, and the water inlet end 304 and the water outlet end 305 are fixedly connected to the spray cooling assembly 3100, and the spray cooling assembly 3100 is used to spray the water inlet end 304 and the water outlet end 305. The cooling water in the cooling water pipe 302, the spray cooling component 3100 includes a water tank 3101, the inner wall of the water tank 3101 is provided with a cooling network 3102, the output end of the water tank 3101 is fixedly connected to the second pump 3103, the second pump 3103 is connected to the water inlet 304, the input end of the water tank 3101 is fixedly connected to the third pump 3104, and the input end of the third pump 3104 is connected to the water outlet 305, and the second pump 3103 and the third pump 3104 are both electrically connected to the PLC control unit 1101.

[0047] The effect achieved by the entire implementation 2 is that the second pump 3103 is started to extract the normal temperature water (water temperature 20-25°C) in the water storage tank 3101, and the water flows into the water pipe 302 through the water inlet end 304, and is evenly sprayed on the surface of the tank body through the atomizing nozzle 303 with a fine mist of 50-100μm particle size. This gas-liquid two-phase flow heat dissipation method uses the sensible heat exchange characteristics of water to achieve precise control of the tank surface temperature. Normal temperature water is close to the ambient temperature, which can not only take away residual heat through droplet evaporation and surface flow, but also avoid the risk of overcooling that may be caused by low-temperature refrigerant (butter solidification point 32-46°C). The water after spraying passes through the surface of the tank body. The diversion trough converges to the water outlet 305 and is transported by the third pump 3104 to the cooling network 3102 for heat exchange and cooling. The cooling network 3102 is woven with high-density polyethylene fibers and has a large specific surface area. The water temperature is reduced to the ambient temperature ±2°C by forced air cooling or natural convection. The cooled water flows back to the water storage tank 3101 to form a closed circulation system. The spray temperature control module works in conjunction with the front-end honeycomb heat exchange component 200 to achieve a smooth transition from active refrigerant cooling to passive water film temperature control, ensuring that the tank surface temperature is stably maintained in the range of 35-40°C, effectively preventing butter from solidifying and clogging due to excessive cooling.

[0048] Embodiment 3, as Figure 4 , Figure 6 as well as Figure 10As shown in the figure: A magnetic field control component 400 is fixedly installed on the inner surface wall of the hollow sandwich layer 107. The magnetic field control component 400 includes a set of fixed rings 401, and a set of electromagnetic windings 402 are installed inside each fixed ring 401. A silicon carbide drive module 403 is fixedly installed on the top of one of the fixed rings 401, and the silicon carbide drive module 403 is electrically connected to each group of electromagnetic windings 402. The output end of the silicon carbide drive module 403 is electrically connected to a PLC control unit 1101. A heat insulation plate 404 is fixedly installed at the bottom of the outer surface wall of the outer shell 102. An infrared thermal imager 405 is fixedly installed on the inner surface wall of the heat insulation plate 404, and the infrared thermal imager 405 is electrically connected to the PLC control unit 1101. A filtering component 500 is arranged at the bottom of the cooling tank body 100. The filtering component 500 includes a funnel 501. The funnel 501 is fixedly communicated with the bottom of the outer shell 102. The bottom of the funnel 501 is fixedly communicated with a sedimentation tank 502. A slag discharge end 503 is arranged at one end of the outer wall of the sedimentation tank 502. A motor 504 is fixedly installed on the top of the cover 108. The output end of the motor 504 is fixedly connected to a transmission rod 505. A connecting rod 506 is fixedly sleeved at the bottom of the transmission rod 505. A conical filter screen 507 is installed at the top of the connecting rod 506. A set of stirring rods 508 are fixedly sleeved on the outer surface wall of the transmission rod 505. An ultrasonic transducer 509 is arranged on one side of the outer wall of the funnel 501. The input end of the ultrasonic transducer 509 is electrically connected to an ultrasonic generator 510, and the ultrasonic generator 510 is electrically connected to the PLC control unit 1101. Each group of fixed liners 301 are installed on the inner surface wall of the cooling sandwich layer 105, and a set of fixed rings 401 are fixedly installed on the inner surface wall of the outer shell 102.

[0049] The effect achieved by the entire Embodiment 3 is that the infrared thermal imager 405 conducts real-time temperature monitoring on the surface of the tank body, constructs a temperature field distribution model with an accuracy of ±1°C through infrared thermal imaging technology. When the system identifies that the temperature in a local area exceeds 65°C, the PLC control unit 1101 immediately outputs a pulse signal to the electromagnetic windings 402 at the corresponding position through the silicon carbide drive module 403. Based on the magnetophoresis effect of the magnetite nanoparticles in the magnetofluid working medium, a gradient magnetic field is formed in the local flow channel. The directional driving force generated by this magnetic field can accurately regulate the flow rate of the magnetofluid, increasing the refrigerant flow rate in the high-temperature area by 30%-50%, significantly enhancing the local heat transfer efficiency. In the crystal separation module, after receiving the PLC instruction, the servo motor 504 drives the transmission rod 505 to rotate, driving the conical filter screen 507 to generate a centrifugal force field. Under the action of the centrifugal force, the precipitated crystals with a certain particle size are thrown towards the inner wall of the sedimentation tank 502 and slide down along the conical surface to gather at the bottom. At this time, the ultrasonic generator 510 applies a high-frequency ultrasonic vibration of 20-40 kHz to the conical filter screen 507 through the ultrasonic transducer 509, and the vibration amplitude is controlled within 5-10 μm, effectively destroying the crystal adhesion layer on the surface of the filter screen, preventing the micron-sized particles from blocking the filter holes, and ensuring the long-term stable operation of the separation system.

[0050] The working principle of the whole device is as follows: First, preliminary heat exchange is carried out. High-temperature beef tallow at 90°C - 100°C enters the interior of the tank through the oil delivery port 110, and then is broken into micron-sized droplets by the beef tallow atomizer 111. The atomization treatment greatly enhances the heat exchange efficiency between the beef tallow and the tank wall. These atomized droplets flow downward along the spiral diversion groove 104 in a spiral trajectory. The structure of the spiral diversion groove 104 increases the flow path length by 40% and induces a turbulent effect, resulting in an increase in the initial heat exchange rate by more than 25%. The graphene heat conduction layer 103 on the inner side of the tank wall can quickly conduct heat to the phase change interlayer 105 on the outside (the set phase change point is 60°C). When the infrared thermal imager 405 monitors that the temperature of the tank drops to 60°C, the phase change material changes from solid to liquid, absorbing the remaining heat during this process. At the same time, the PLC control unit 1101 starts the first pump 2106 to extract the ethylene glycol refrigerant in the liquid storage tank 2105. The refrigerant is injected into the honeycomb microchannel 201 through the liquid inlet pipe 202. The micron-sized flow channels of the honeycomb structure provide a large specific surface area, enabling the refrigerant to conduct efficient heat exchange with the tank wall and gradually reducing the temperature from 60°C to 40°C. The heat-absorbed refrigerant flows into the condenser tube 2102 through the liquid outlet pipe 203. At this time, the cooling fan 2104 starts, accelerating the heat dissipation on the surface of the condenser tube 2102 through forced convection. The cooled refrigerant returns to the liquid storage tank 2105 through the return pipeline, forming a closed-loop system. The heat dissipation fins 109 outside the tank are made of nickel-titanium alloy memory metal and can automatically adjust the deployment angle according to the surface temperature of the tank. When the temperature is higher than 45°C, the fins automatically deploy to the maximum heat dissipation area (the deployment angle ≥ 90°), and when the surface of the tank is lower than 35°C, they fold and fit the tank (the folding angle ≤ 30°), effectively reducing the floor area of the system while ensuring the heat dissipation efficiency;

[0051] Next, intelligent regulation and precise cooling are carried out. The infrared thermal imager 405 continuously scans the surface of the tank in real time to construct a temperature field distribution model of the tank. When it is identified that the local temperature exceeds 60 °C, the PLC control unit 1101 applies a gradient magnetic field to the electromagnetic winding 402 at the corresponding position through the silicon carbide drive module 403. Based on the magnetophoresis effect of the magnetite nanoparticles in the ferrofluid, this magnetic field generates a directional driving force, increasing the refrigerant flow rate in the high-temperature area by 30%-50%. Thus, the local heat transfer efficiency is enhanced. The refrigerant after absorbing heat flows into the condensing pipe 2102 through the liquid outlet pipe 203. At this time, the cooling fan 2104 accelerates the heat dissipation process through forced convection. The cooled refrigerant flows back to the liquid storage tank 2105, forming a closed-loop system. When the temperature of the tank approaches the freezing point of butter, the system automatically switches to the spray temperature control mode. The second pump 3103 extracts the normal temperature water at 20-25 °C in the water storage tank 3101. The normal temperature water passes through the water inlet end 304 and is sprayed onto the surface of the tank in the form of fine mist by the atomizing nozzle 303. Through the sensible heat exchange of water, the surface temperature of the tank is maintained at 35-45 °C, effectively preventing the butter from solidifying due to excessive cooling of the tank. The water after spraying is collected at the water outlet end 305 and transported to the high-density polyethylene cooling net 3102 by the third pump 3104. After cooling to the ambient temperature, it flows back to the water storage tank 3101, forming a closed-loop water circulation system;

[0052] Finally, in the crystal separation module, after receiving the PLC instruction, the servo motor 504 drives the transmission rod 505 to rotate, driving the conical filter screen 507 to generate a centrifugal force field. Under the action of centrifugal force, the precipitated crystals with a certain particle size are thrown towards the inner wall of the sedimentation tank 502 and slide down along the conical surface to gather at the bottom. At this time, the ultrasonic generator 510 applies a high-frequency ultrasonic vibration of 20-40 kHz to the conical filter screen 507 through the ultrasonic transducer 509, and the vibration amplitude is controlled within 5-10 μm, effectively destroying the crystal adhesion layer on the surface of the filter screen, preventing the micron-sized particles from blocking the filter holes, and ensuring the long-term stable operation of the separation system. During the entire cooling process, there is no need for a traditional external compressor cooling unit to participate. Through the collaborative work of the graphene heat conduction layer 103, the phase change interlayer 105, the honeycomb heat exchange component 200, and the heat dissipation fins 109, gradient cooling of the tank is achieved. While ensuring the cooling effect of the tank, the system energy consumption is greatly reduced, with significant energy conservation and environmental protection advantages and application value. In summary, the problems raised in the above background are solved.
