[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1As shown, the heat exchange device for sterilizing fermented bean curd juice includes a high-level feeding tank 1. A discharge pipe 2 is provided at the bottom of the high-level feeding tank 1, and a vibrating screen 3 is provided at one end of the discharge pipe 2. A small square bucket 4 is provided on one side of the vibrating screen 3, and a first feeding pipe 5 is fixedly connected to the bottom of the small square bucket 4. A conveying pump 6 is provided at one end of the first feeding pipe 5, and a fixed pipe 7 is provided at one end of the conveying pump 6. A second feeding pipe 8 is fixedly connected to the outer wall of the fixed pipe 7, and one end of the second feeding pipe 8 is connected to the cold inlet of the first plate heat exchanger 9. A third feeding pipe 10 is provided at the cold outlet of the first plate heat exchanger 9, and a slurry burner group 11 is provided at one end of the third feeding pipe 10. A first discharge pipe 12 is provided at the discharge end of the slurry burner group 11, and one end of the first discharge pipe 12 is connected to the hot inlet of the first plate heat exchanger 9.

[0017] Through the above technical solution, the temperature of the low-temperature material in the second feed pipe 8 and the temperature of the high-temperature material in the first discharge pipe 12 are exchanged through the first plate heat exchanger 9, which can greatly reduce energy consumption. The waste heat of the high-temperature material can be used to preheat the low-temperature material, reducing the need for additional energy and achieving efficient energy utilization. In the industrial process of fermented bean curd production, this heat exchange method can significantly reduce the energy consumption of heating and cooling. Compared with traditional production methods, it can achieve a significant energy saving effect. According to actual application tests, it saves the energy consumption required for cooling hot materials, achieving a 50% energy saving and a 30% increase in speed in the sterilization process. The plate heat exchanger has a high-efficiency heat exchange performance. Through a series of heat exchange plates inside, fluids of different temperatures can transfer heat on both sides of the plates. In the description, the low-temperature material in the second feed pipe 8 usually refers to the material with a relatively low temperature during the production process, which is the material that has not been heated. The high-temperature material in the first discharge pipe 12 usually refers to the material that has undergone a specific treatment process (such as heating, reaction, etc.) and has a higher temperature.

[0018] Specifically, the first plate heat exchanger 9 has a second discharge pipe 13 at its hot outlet, and a booster pump 14 is installed at one end of the second discharge pipe 13. A third discharge pipe 15 is installed at one end of the booster pump 14, and one end of the third discharge pipe 15 is connected to the hot inlet of the second plate heat exchanger 16. The cold inlet of the second plate heat exchanger 16 is connected to the cooling water pipe 17. The second plate heat exchanger 16 has a fourth discharge pipe 18 at its hot outlet, and a drain pipe 21 is installed at the bottom of the slurry burner group 11.

[0019] Through the above technical solution, the material that has been initially cooled in the first plate heat exchanger 9 is pressurized by the booster pump 14 and enters the second plate heat exchanger 16 through the third discharge pipe 15. Cooling water enters the second plate heat exchanger 16 through the cooling water pipe 17 to perform secondary cooling on the material in the third discharge pipe 15. The secondary cooling further reduces the temperature of the material, ensuring that the material can reach the optimal temperature conditions required for subsequent processes.

[0020] Specifically, the outer wall of the fourth discharge pipe 18 is connected to a valve via a pipe, and one end of the valve is equipped with a cleaning return pipe 19, one end of which extends into the small square bucket 4.

[0021] Through the above technical solution, by setting up a cleaning return pipe 19, some materials and impurities will inevitably remain inside the equipment during the production process, requiring cleaning. The cleaning return pipe 19 can return the cleaning liquid to the small square bucket 4, realizing the recycling of the cleaning liquid and reducing the waste of cleaning liquid. At the same time, the cleaning liquid can continuously flush various parts inside the equipment during the circulation process, ensuring that the equipment is thoroughly cleaned.

[0022] Specifically, the outer wall of the fixed pipe 7 is connected to a valve via a pipe, and one end of the valve is provided with a residual material pipe 20, one end of which is connected to the high-level feed tank 1.

[0023] Through the above technical solution, the residual material extraction pipe 20 can draw the residual material in the equipment back to the high-level feed hopper 1, avoiding material waste. During the production process, due to various reasons, some incompletely processed materials may remain inside the equipment. By setting up the residual material extraction pipe 20, these residual materials can be collected and reprocessed, improving the utilization rate of materials and reducing production costs.

[0024] In use, the raw material for fermented bean curd juice is first stored in a high-level feed tank 1. Under gravity, the raw material enters a vibrating screen 3 through a feed pipe 2. The vibrating screen 3 screens the raw material to remove impurities, ensuring the purity of the raw material entering subsequent processes. The screened raw material enters a small square tank 4 for temporary storage. The first feed pipe 5 at the bottom of the small square tank 4, under the action of a feed pump 6, transports the raw material to a fixed pipe 7. The raw material enters a second feed pipe 8 through the fixed pipe 7. The raw material enters the cold inlet of the first plate heat exchanger 9 through the second feed pipe 8. The raw material enters a third feed pipe 10 through the cold outlet of the first plate heat exchanger 9. The raw material enters the burner group 11 from the third feed pipe 10 for heating treatment. The material exits through the first discharge pipe 12. The high-temperature material entering the hot inlet of the first plate heat exchanger 9 through the first discharge pipe 12 from the discharge end of the burner group 11 exchanges heat with the low-temperature material in the second feed pipe 8 in the first plate heat exchanger 9. The heat of the high-temperature material is transferred to the low-temperature material, causing the temperature of the low-temperature material to rise, while the high-temperature material... The temperature of the warm material decreases, thus utilizing the waste heat of the high-temperature material to preheat the low-temperature material, reducing the energy demand in subsequent heating processes. After heat exchange, the material flows out from the hot outlet of the first plate heat exchanger 9 through the second discharge pipe 13. Under the pressure of the booster pump 14, the material in the second discharge pipe 13 enters the third discharge pipe 15, and then enters the hot inlet of the second plate heat exchanger 16. Cooling water enters the cold inlet of the second plate heat exchanger 16 through the cooling water pipe 17. Inside the second plate heat exchanger 16, the cooling water exchanges heat with the material in the third discharge pipe 15, performing secondary cooling on the material and further reducing its temperature to reach the optimal temperature conditions required for subsequent processes. The cooled material exits from the hot outlet of the second plate heat exchanger 16 into the fourth discharge pipe 18, ready to enter the next production stage. This completes all the work. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
