[0029] Please see Figures 1-5In this embodiment of the present invention, a cooling device for yogurt beverage production includes a refrigerator 1, a refrigerant tank 2, a heat exchanger 3, and an insulation tank 4. The heat exchanger 3 includes a first return pipe 31 and a second return pipe 32 for heat exchange. The refrigerant tank 2 is provided with a refrigerant output pipe 21 and a refrigerant input pipe 22. The refrigerant output pipe 21 is connected to the input end of the refrigerator 1. The output end of the refrigerator 1 is connected to one end of the first return pipe 31. The first return pipe 31 is provided with a first water pump 33. The other end of the first return pipe 31 is connected to the input end of the first water pump 33. The output end of the refrigerant tank 2 is connected to the refrigerant input pipe to form a first circulation loop. The insulated tank 4 is equipped with a second water pump 41, an insulated input pipe 42, and an insulated output pipe 43. The insulated output pipe 43 is connected to the input end of the second water pump 41. The second water pump 41 is connected to one end of the second return pipe 32, and the other end of the second return pipe 32 is connected to the second circulation loop of the insulated input pipe 42. The insulated tank 4 is equipped with a cooling conduit 44, which is installed on the surface of the insulated tank 4 near its lower end. One end of the cooling conduit 44 connects to the interior of the insulated tank 4, and the other end extends out of the surface of the insulated tank 4. The refrigeration unit 1 and the refrigerant tank 2 are connected via pipelines. Specifically, the refrigerant medium includes, but is not limited to, water and sodium chloride aqueous solution. The first water pump 33 can draw refrigerant from the refrigerant tank 2 and transfer it to the refrigeration unit 1 for cooling. After cooling by the refrigeration unit 1, the refrigerant is transferred through pipelines to the heat exchanger 3 and then back to the refrigerant tank 2. The chiller 1 can be of various types, including air-cooled chillers and centrifugal chillers. The second water pump 41 draws process water stored in the insulated tank 4 to the heat exchanger 3 for cooling. After heat exchange with the refrigerant in the heat exchanger 3, the process water returns to the insulated tank 4 for storage. The germicidal lamp 443 can be of various types, including but not limited to UV germicidal lamps, plasma germicidal lamps, and UVC ultraviolet lamps.

[0030] The working principle of this embodiment is as follows: By setting up a cooling device, the refrigerator 1 and the refrigerant tank 2 output low-temperature refrigerant. The low-temperature refrigerant exchanges heat with the process water flowing through the second return pipe 32 in the heat exchanger 3 via the first return pipe 31. This reduces the heat of the process water and keeps it in the heat exchanger 4. The process water is then output through the cooling pipe 44 for the production of lactic acid beverages. This ensures that the lactic acid beverages are in a suitable low-temperature state during production, which can effectively prevent the separation of lactic acid beverages.

[0031] In another embodiment of this utility model, such as Figure 1 As shown, during the production of lactic acid beverages, the process water in the insulated tank 4 is transported to the ingredient tank 6 used for beverage production via the cooling pipe 44, so that the beverage production process can maintain a low temperature and avoid stratification due to excessive temperature.

[0032] In another embodiment of this utility model, the process water can be cooled to a temperature between 0°C and 10°C. Selectable process water temperatures include 0°C, 3°C, 5°C, and 8°C. The cooled process water can be used in the acid spraying process of lactic acid beverage production. In the prior art, the acid spraying temperature is too high, which causes the product to separate after a long storage time. In this embodiment, the original addition of room temperature process water is replaced with the addition of ice process water, which can reduce the original acid spraying temperature. Lowering the acid spraying temperature can solve the product separation problem, improve the stability of yogurt beverage products, and extend the storage time.

[0033] Further as Figure 1 and Figures 5-6 As shown in this embodiment of the invention, the cooling conduit 44 is equipped with a valve 45, which is installed at the connection between the cooling conduit 44 and the insulation tank 4. The valve 45 can be a shut-off valve. The flow state of the process water in the cooling conduit 44 can be controlled by the valve 45. Opening the valve 45 allows the process water in the insulation tank 4 to flow out of the cooling conduit 44 and be used in beverage production. When the set output is reached, the valve 45 can be closed to prevent the process water from flowing out of the cooling conduit 44.

[0034] Further as Figures 1-2 and Figures 5-6 As shown in this embodiment of the invention, the cooling conduit 44 includes an outer tube 441, an inner tube 442, and a germicidal lamp 443. The outer tube 441 is fitted over the inner tube 442, forming an irradiation gap between the inner tube 442 and the outer tube 441. The outer tube 441 has at least two mounting grooves 444, which connect to the irradiation gap. The germicidal lamp 443 is detachably installed in the mounting grooves 444 for irradiating the inner tube 442. The inner tube 442 is made of a light-transmitting material. Specifically, the material of the inner tube 442 includes, but is not limited to, polytetrafluoroethylene (PTFE), polycarbonate (PC), polyethylene (PE), and polyvinyl chloride (PVC). The connection method between the germicidal lamp 443 and the outer tube includes, but is not limited to, snap-fit ​​connection and adhesive bonding. The working principle of this embodiment is as follows: By installing a germicidal lamp 443 inside the cooling conduit 44, the germicidal lamp 443 can effectively irradiate the process water flowing through the inner tube 442, thereby preventing the growth and excessive levels of microorganisms.

[0035] Further as Figures 1-2 As shown in this embodiment of the invention, the inner tube 442 is made of polyethylene. The inner tube 442, produced by injection molding using polyethylene as raw material, has good low-temperature resistance and is also translucent, allowing ultraviolet light or other bactericidal light to pass through.

[0036] Further as Figure 2As shown in this embodiment of the invention, the outer tube 441 has four circumferentially evenly spaced mounting slots 444, and four germicidal lamps 443 are correspondingly mounted on the outer tube 441, with each lamp installed in one of the mounting slots 444. The working principle of this embodiment is as follows: the four sets of germicidal lamps 443 can evenly irradiate the inner tube 442. Even if a single lamp malfunctions, it will not affect the overall effect. Furthermore, the multi-point irradiation ensures thorough sterilization and avoids sterilization dead zones.

[0037] Further as Figures 5-6 As shown in this embodiment of the invention, the insulated tank 4 includes an outer cover 46, an inner liner 47, and a sealing cap 48. The outer cover 46 has a mounting hole 461, and the inner liner 47 is disposed within the mounting hole 461. The outer surface of the inner liner 47 has at least two guide grooves 471, and the mounting hole 461 has at least two guide blocks 462. The guide blocks 462 are evenly distributed circumferentially on the inner wall of the mounting hole 461 and are respectively inserted into the guide grooves 471. The gap between the outer cover and the inner liner 47 is filled with insulation material. The sealing cap 48 is installed at the upper end of the outer cover 46 to seal the gap between the outer cover 46 and the inner liner 47. The inner liner 47 and the outer cover 46 are connected by mutual insertion and engagement through the guide blocks 462 and the guide grooves 471. The inner liner 47 and the outer cover 46 are detachable, facilitating disassembly and assembly and improving convenience. The insulation material can be polyurethane foam, which serves as the insulation layer of the insulated tank 4, reducing heat transfer and improving insulation performance.

[0038] Further as Figures 5-6 As shown in this embodiment of the invention, the insulated tank 4 is equipped with a temperature sensor 49 and a high / low level switch 50. The temperature sensor 49 is installed inside the inner liner 47, and the high / low level switch 50 is installed on the outer wall of the outer casing 46. Specifically, the high / low level switch 50 is equipped with a level sensor that can detect the water level of the process water in the insulated tank 4 in real time to prevent overflow. The temperature sensor can detect the temperature of the process water in real time and control the temperature to ensure no microbial quality risk.

[0039] Further as Figures 5-6 As shown in this embodiment of the invention, the heat preservation tank 4 further includes a mounting cover 51, which is hinged to the upper surface of the heat preservation tank 4. Specifically, a silicone sealing ring is provided at the joint between the mounting cover 51 and the heat preservation tank 4 to enhance the seal and improve the heat preservation effect.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
