Description

Technical Field

[0001] This utility model relates to the field of dairy product cooling technology, and in particular to a dairy product cooling device. Background Technology

[0002] High-temperature sterilization is required during the production of dairy products. After sterilization, the dairy products are at a very high temperature and need to be cooled before further processing.

[0003] Currently, the cooling of high-temperature dairy products often involves directly transporting milk through pipes through a stream of room-temperature water, allowing the water to carry away the heat. However, high-temperature sterilized dairy products are very hot (100°C or even higher), and cooling them with only room-temperature water results in a slow cooling rate and insufficient cooling. Therefore, there is an urgent need to develop a dairy product cooling device that first uses airflow for primary cooling, then room-temperature water for secondary cooling, and finally low-temperature water for tertiary cooling, resulting in faster and more thorough cooling. This device would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a dairy product cooling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dairy product cooling device includes a support frame, a heat dissipation mechanism, fans, an ambient temperature water-cooled box, a low temperature water-cooled box, an industrial chiller, a water pump, a guide pipe, a first heat exchange pipe, a second heat exchange pipe, a connecting pipe, and a rotary drive mechanism. The heat dissipation mechanism is fixed on the support frame, and multiple fans are fixedly mounted on the support frame to blow air onto the heat dissipation mechanism. The heat dissipation mechanism includes: a branching annular pipe, a converging annular pipe, a milk inlet pipe, a milk outlet pipe, and spiral heat dissipation pipes. Multiple spiral heat dissipation pipes are fixedly connected between the branching annular pipe and the converging annular pipe. A milk inlet pipe is fixed on the branching annular pipe, and a milk outlet pipe inserted into the ambient temperature water-cooled box is fixed on the converging annular pipe. A first heat exchange tube is rotatably connected to the low-temperature water-cooled box, and a second heat exchange tube is fixed inside the low-temperature water-cooled box. The lower end of the first heat exchange tube is inserted into the milk outlet tube and rotatably connected thereto. The upper ends of the first and second heat exchange tubes are connected through a connecting pipe. The upper end of the first heat exchange tube is inserted into the connecting pipe and rotatably connected thereto. The upper end of the second heat exchange tube is fixed to the connecting pipe. The water inlet of the water pump is connected to a water pumping pipe inserted into the low-temperature water-cooled box, and the water outlet of the water pump is connected to a water supply pipe inserted into an industrial chiller. A guide pipe is connected between the low-temperature water-cooled box and the industrial chiller. A rotary drive mechanism for driving the first heat exchange tube to rotate is installed on the top of the room-temperature water-cooled box.

[0007] Preferably, a water inlet pipe is fixed to the top of the ambient temperature water-cooled box, and a drain pipe is fixed to the bottom of the ambient temperature water-cooled box.

[0008] Preferably, the first heat exchange tube has multiple heat-conducting fins fixed on it.

[0009] Preferably, the rotary drive mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed to the top of the ambient temperature water-cooled box. The first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it. The second gear is fixed to the upper end of the first heat exchange tube.

[0010] Preferably, the spiral heat dissipation tube, the first heat exchange tube, the heat-conducting fins, and the second heat exchange tube are all made of copper.

[0011] Preferably, the lower end of the second heat exchange tube is fixed with an output tube extending to the outside of the low-temperature water-cooled box.

[0012] The beneficial effects of this invention are as follows: In use, the high-temperature sterilized milk source is transported to a distribution ring pipe, which then disperses the milk into multiple spiral cooling pipes to reduce milk concentration and facilitate heat dissipation. A fan blows air onto the spiral cooling pipes, thereby lowering the temperature of the milk within them, achieving primary cooling. The milk is then transported from the outlet pipe to the first heat exchange pipe, while tap water enters the ambient temperature water-cooled tank through the inlet pipe and exits through the drain pipe. This water flow carries away heat from the first heat exchange pipe. Simultaneously, the heat-conducting fins increase the contact area between the first heat exchange pipe and the water flow. The device is then driven by a motor. The rotation of the first and second gears drives the rotation of the first heat exchange tube, thereby increasing the contact between the first heat exchange tube and the water flow, improving the cooling effect, and achieving secondary cooling of the milk. Then, the milk is transported from the connecting pipe to the second heat exchange tube. A water pump then transports the water from the low-temperature water-cooling box to an industrial chiller, which cools the water. The cooled water then flows back into the low-temperature water-cooling box through the guide pipe, maintaining a low-temperature water flow within the box. This low-temperature water flow further cools the milk in the second heat exchange tube, achieving tertiary cooling of the milk and significantly reducing its temperature. Finally, the cooled milk is discharged from the output pipe. In summary, this invention first uses airflow for primary cooling of the milk, then uses room-temperature water for secondary cooling, and finally uses low-temperature water for tertiary cooling, resulting in faster and more thorough cooling.

The heat dissipation mechanism 2 is fixed on the support 1, and multiple fans 3 are fixedly installed on the support 1 to blow air onto the heat dissipation mechanism 2. The heat dissipation mechanism 2 includes: a diversion annular pipe 201. The system comprises a collecting ring pipe 202, a milk inlet pipe 203, a milk outlet pipe 204, and a spiral heat dissipation pipe 205. Multiple spiral heat dissipation pipes 205 are fixedly connected between the diverting ring pipe 201 and the collecting ring pipe 202. A milk inlet pipe 203 is fixed to the diverting ring pipe 201 and connected to an external milk source via a pipe. A milk outlet pipe 204, inserted into a room-temperature water-cooled box 4, is fixed to the collecting ring pipe 202. A first heat exchange pipe 9 is rotatably connected inside the room-temperature water-cooled box 4. A second heat exchange pipe 10 is fixed inside a low-temperature water-cooled box 5. The lower end of the first heat exchange pipe 9 is inserted into the milk outlet pipe 204 and rotatably connected to it. The first heat exchange pipe 9 and the milk outlet pipe 204 are connected by a sealing ring (not shown in the figure) to prevent leakage. The upper ends of the first heat exchange pipe 9 and the second heat exchange pipe 10 are connected by a connecting pipe 11. The upper end of the first heat exchange pipe 9 is inserted into the connecting pipe 11 and rotatably connected to it. The upper end of the second heat exchange pipe 10 is fixed to the connecting pipe 11, and the lower end of the second heat exchange pipe 10 is fixed with an output pipe 1001 extending to the outside of the low-temperature water-cooled box 5. The cooled milk is finally discharged from the outlet pipe 204. The water is discharged through the outlet pipe 1001. The inlet end of the water pump 7 is connected to the water pump pipe 701 inserted into the low-temperature water-cooled box 5. The outlet end of the water pump 7 is connected to the water supply pipe 702 inserted into the industrial chiller 6. A guide pipe 8 is connected between the low-temperature water-cooled box 5 and the industrial chiller 6 (the industrial chiller 6 is an existing technology product used to cool and cool water flow). The low-temperature water-cooled box 5 is used to store cold water. The water flow in the low-temperature water-cooled box 5 is transported to the industrial chiller 6 through the water pump 7. The industrial chiller 6 cools the water flow. The cold water then flows back to the low-temperature water-cooled box 5 through the guide pipe 8, thereby maintaining the low-temperature water flow in the low-temperature water-cooled box 5.

[0023] A water inlet pipe 401 is fixed to the top of the ambient temperature water-cooled box 4. The water inlet pipe 401 is connected to an external tap water source through a pipe (not shown in the figure). A drain pipe 402 is fixed to the bottom of the ambient temperature water-cooled box 4. The drain pipe 402 is connected to a sewer through a pipe (not shown in the figure). Tap water enters the ambient temperature water-cooled box 4 from the water inlet pipe 401 and is discharged from the drain pipe 402, thereby carrying away the heat on the first heat exchange tube 9 through the water flow.

[0024] Multiple heat-conducting fins 901 are fixed on the first heat exchange tube 9. The heat-conducting fins 901 increase the contact area between the first heat exchange tube 9 and the water flow, thereby improving the cooling effect. A rotary drive mechanism 12 is installed on the top of the room temperature water-cooled box 4 to drive the first heat exchange tube 9 to rotate. The rotary drive mechanism 12 drives the first heat exchange tube 9 to rotate, thereby making the contact between the first heat exchange tube 9 and the water flow more sufficient.

[0025] The rotary drive mechanism 12 includes a drive motor 1201, a first gear 1202, and a second gear 1203. The drive motor 1201 is fixed to the top of the ambient temperature water-cooled box 4. The first gear 1202 is fixed on the output shaft of the drive motor 1201. A second gear 1203 is provided on one side of the first gear 1202 and meshes with it. The second gear 1203 is fixed to the upper end of the first heat exchange tube 9. In use, the drive motor 1201 drives the first gear 1202 and the second gear 1203 to rotate. The rotation of the second gear 1203 drives the first heat exchange tube 9 to rotate, thereby making the first heat exchange tube 9 more fully contacted with the water flow and improving the cooling effect.

[0026] The spiral heat sink 205, the first heat exchange tube 9, the heat-conducting fins 901, and the second heat exchange tube 10 are all made of copper, giving them good thermal conductivity.

[0027] All of the above-mentioned electrical components use external power grid electricity.

[0028] Working Principle: In operation, this dairy product cooling device delivers high-temperature sterilized milk to a distribution ring pipe 201. The ring pipe 201 then disperses the milk into multiple spiral cooling pipes 205 to reduce milk concentration and facilitate heat dissipation. A fan 3 blows air onto the spiral cooling pipes 205, lowering the milk temperature and achieving primary cooling. The milk then flows from the outlet pipe 204 to the first heat exchange pipe 9. Tap water enters the ambient temperature water-cooled tank 4 through the inlet pipe 401 and exits through the drain pipe 402, thus carrying away heat from the first heat exchange pipe 9. Simultaneously, the heat-conducting fins 901 increase the contact area between the first heat exchange pipe 9 and the water flow. The drive motor 1201 then drives the... The rotation of gear 1202 and gear 1203 drives the rotation of the first heat exchange tube 9, thereby increasing the contact between the first heat exchange tube 9 and the water flow, improving the cooling effect, and achieving secondary cooling of the milk. Then, the milk is transported from the connecting pipe 11 to the second heat exchange tube 10. The water pump 7 transports the water flow in the low-temperature water-cooled box 5 to the industrial chiller 6. The industrial chiller 6 cools the water flow, and the cooled water flows back to the low-temperature water-cooled box 5 from the guide pipe 8, thereby maintaining the low-temperature water flow in the low-temperature water-cooled box 5. The low-temperature water flow cools the milk in the second heat exchange tube 10 again, achieving tertiary cooling of the milk, thereby fully reducing the temperature of the milk. Finally, the cooled milk is discharged from the output pipe 1001.
