Technical Field

[0001] The utility model relates to the field of food processing, in particular to a circulating heat exchange system for food cooling and raw material thawing. Background Art

[0002] In the food processing industry, especially for products that require raw material thawing and rapid cooling, traditional cooling methods often have high energy consumption and low efficiency. Generally, after high-temperature sterilization, products need to be quickly cooled to ensure quality and safety. However, traditional air-cooling or natural cooling methods are not only slow, but also difficult to control the cooling rate, which may lead to changes in product texture or recontamination by microorganisms. In addition, the cooling process consumes a large amount of energy, increasing production costs.

[0003] More critically, in many food production lines, there are multiple processes that require water at different temperatures, such as raw material thawing. These processes usually operate independently and lack an effective energy integration and recycling mechanism, resulting in energy waste. How to effectively recover and utilize the waste heat in the production process, reduce energy consumption, and ensure the efficient operation of each production link has become a technical problem to be solved urgently. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a circulating heat exchange system for food cooling and raw material thawing, which solves the problems of high energy consumption in the cooling process, increased production costs, and lack of effective energy integration and recycling mechanism, resulting in energy waste.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a circulating heat exchange system for food cooling and raw material thawing, including a cooling pool and a thawing pool. The thawing pool is connected to the cooling pool through a first pump body. The cooling pool is connected to a heating pool through a third pump body. The heating pool is connected to the thawing pool through a second pump body to form a cycle.

[0006] Hanging frames are provided above both the cooling pool and the thawing pool. Storage nets are provided inside both the cooling pool and the thawing pool. The storage nets are connected to the cranes on the hanging frames.

[0007] In a preferred embodiment, a water inlet coil is provided on the inner wall of the thawing pool. The water inlet is arranged at the upper end of the water inlet coil, and the lower end of the water inlet coil is connected to a water spraying plate.

The just-taken-out bagged egg dumplings have a very high temperature and quickly exchange heat with the cold water in the cooling pool to cool down. The cold water that absorbs heat in the cooling pool becomes hot water and is then pumped by a circulating pump to the thawing pool of the frozen vegetables of the egg dumpling raw materials for thawing the frozen vegetables; during the thawing process, the hot water loses heat and becomes cold water and continues to circulate to the cooling pool of the egg dumplings to cool down the egg dumplings. Thus, the heat of the egg dumplings is provided to thaw the frozen vegetables through repeated circulation, and the egg dumplings are also cooled down.

The thawing pool 4 is connected to the cooling pool 2 through a first pump body 3. The cooling pool 2 is connected to a heating pool 6 through a third pump body 8. The heating pool 6 is connected to the thawing pool 4 through a second pump body 5 to form a cycle.

[0021] Hanging frames 1 are provided above both the cooling pool 2 and the thawing pool 4. Storage nets 10 are provided inside both the cooling pool 2 and the thawing pool 4. The storage nets 10 are connected to the cranes 102 on the hanging frames 1.

[0022] The cooling pool 2 is used to receive the egg dumplings after high-temperature sterilization and quickly exchange heat with cold water to cool down the egg dumplings. The thawing pool 4 is used to thaw raw materials such as frozen vegetables required for the egg dumplings. The first pump body 3 connects the thawing pool 4 and the cooling pool 2 and is responsible for sending the cold water in the thawing pool back to the cooling pool. The third pump body 8 connects the cooling pool 2 and the heating pool 6 and is responsible for sending the hot water in the cooling pool to the heating pool. The heating pool 6 is connected to the thawing pool 4 through the second pump body 5 and is used to heat the water in the thawing pool. The second pump body 5 connects the heating pool 6 and the thawing pool 4 and is responsible for sending the hot water in the heating pool into the thawing pool. The hanging frame 1 is provided above the cooling pool 2 and the thawing pool 4 and is used to hoist the storage net 10.

[0023] Implementation steps

[0024] Sterilization and preliminary cooling of egg dumplings: Put the vacuum-packed egg dumplings into a steamer for high-temperature sterilization treatment, and then take out the high-temperature egg dumplings from the steamer and put them into the cooling pool 2 for preliminary cooling. The cold water in the cooling pool 2 comes into contact with the high-temperature egg dumplings for rapid heat exchange, and the cold water absorbs heat and becomes hot water.

[0025] The hot water that has absorbed heat is pumped from the cooling pool 2 to the heating pool 6 through the third pump body 8. After the heating pool 6 reheats the water, it is transported to the thawing pool 4 for thawing frozen vegetables. The hot water loses heat in the thawing pool 4 to help thaw the frozen raw materials.

[0026] The thawed cold water circulates back to the cooling pool 2 through the first pump body 3 to continue cooling the new batch of egg dumplings.

[0027] The above steps are carried out in a cycle to effectively transfer the heat of the egg dumplings to the thawing process of the frozen vegetables, ultimately achieving the purpose of saving energy.

[0028] Through the circulating heat exchange system, rapid cooling of egg dumplings and efficient thawing of frozen vegetables are achieved, effectively saving energy. The circulation system simplifies the production process, speeds up the product processing speed, and improves the efficiency of the overall production line. The recycling of heat reduces the demand for additional energy, meeting the production concept of green environmental protection. Through rapid cooling, the taste and quality of egg dumplings are guaranteed, and at the same time, the nutrient loss of vegetables during the thawing process is avoided.

[0029] In the preferred embodiment, the inner wall of the thawing tank 4 is provided with a water inlet coil 9, the water inlet 901 is arranged at the upper end of the water inlet coil 9, and the lower end of the water inlet coil 9 is communicated with the water spraying plate 11.

The water heated by the heating tank 6 is delivered to the inside of the thawing tank 4 through the water inlet 901 of the thawing tank 4. After the hot water enters the thawing tank 4, it heats the water in the thawing tank 4 through the water inlet coil 9. The hot water flows from the lower end of the water inlet coil 9 to the water spraying plate 11 and is evenly sprayed on the food raw materials in the thawing tank 4 through the plurality of water spraying holes 1101 on the water spraying plate 11 to achieve large-area spray thawing.

[0035] The water outlet 401 at the lower end of the thawing tank 4 sends the water that has lost heat and become cold water back to the water inlet of the cooling tank 2 through the first pump body 3 to prepare for the next cycle.
