The cooling step includes room temperature water cooling and ice water cooling. The blanched vegetables are first cooled with room temperature water, and then further cooled with ice water. This results in vegetables entering the freezing step at a lower temperature, saving energy consumed in the freezing process.

[0003] In the ice water cooling step, ice water needs to be prepared using a heat exchanger. However, the heat exchangers in the existing technology have low heat exchange efficiency and poor heat exchange effect. In addition, the pipes and other components in the existing heat exchangers are not easy to disassemble and are inconvenient to clean. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is implemented as follows: a chilled water heat exchanger for a vegetable production line, comprising: a heat exchange plate, a water tank, and a water distribution assembly;

[0006] The heat exchange plate is a rectangular plate structure with a honeycomb pattern on both sides and a honeycomb flow space inside. The heat exchange plate is vertically arranged, with an inlet communicating with the flow space at the top and an outlet communicating with the flow space at the bottom on one side wall of the heat exchange plate.

[0007] The top of the water tank has an open structure, and the opening of the water tank is located directly below the heat exchange plate;

[0008] The water distribution assembly is located on top of the heat exchange plate. The water distribution assembly includes a water distribution pipe, a U-shaped end, and a water inlet end. Two water distribution pipes are symmetrically arranged on both sides of the heat exchange plate. Multiple water distribution holes are inclined on the side of the water distribution pipe closest to the heat exchange plate, arranged at intervals along the length of the water distribution pipe.

The water inlet end is located at the other end of the two water distribution pipes and has one inlet end and two connecting ends, which are interconnected. The two connecting ends are connected to the other end of the water distribution pipe via detachable assemblies.

[0009] As a further technical solution, the two ports of the U-shaped end are respectively connected to one end of the two water distribution pipes to form a first connection part, and a gasket is provided between each port and the end of the water distribution pipe; the two connecting ends of the water inlet end are respectively connected to the other end of the two water distribution pipes to form a second connection part, and a gasket is provided between each connecting end and the other end of the water distribution pipe.

[0010] As a further technical solution, the detachable component includes two semi-circular retaining rings and a pin.

[0028] like Figures 1-6 As shown, this utility model proposes an ice-water heat exchanger for a vegetable production line, including: a heat exchange plate 1, a water tank 2, and a water distribution assembly 3.

[0029] The heat exchange plate 1 is a rectangular plate structure, such as... Figure 1 and Figure 2 As shown, both its front and back sides are honeycomb-shaped, and its interior has honeycomb-shaped flow spaces, such as... Figure 6 As shown. The heat exchange plate 1 is vertically arranged. The upper part of one side wall of the heat exchange plate 1 is provided with an inlet 11 communicating with the flow space, and the lower part is provided with an outlet 12 communicating with the flow space.

[0030] like Figure 2 As shown, the water distribution assembly 3 is located on top of the heat exchange plate 1; Figure 3 , Figure 4 As shown, the water distribution assembly 3 includes a water distribution pipe 30, a U-shaped end 31, and a water inlet end 32. Two water distribution pipes 30 are provided, symmetrically arranged on both sides of the heat exchange plate 1. Multiple water distribution holes 300 are inclinedly provided on the side of the water distribution pipe 30 closest to the heat exchange plate 1, and these holes are arranged at intervals along the length of the water distribution pipe 30. The U-shaped end 31 is located at one end of the two water distribution pipes 30 and has two interconnected ports 310. The two ports 310 are connected to the ends of the two water distribution pipes 30 via detachable components 4, and each port 310 is interconnected with the end of its corresponding water distribution pipe 30. The water inlet end 32 is located at the other end of the two water distribution pipes 30. The water inlet end 32 has a water inlet end 321 and two connecting ends 320. The water inlet end 321 and the two connecting ends 320 are interconnected. The two connecting ends 320 are respectively connected to the other end of the water distribution pipe 30 through the detachable component 4.

[0031] like Figure 1 As shown, the top of the water tank 2 in this application is an open structure, the opening of the water tank 2 is located directly below the heat exchange plate 1, and a water outlet 20 communicating with it is provided on one side of the water tank 2.

[0032] In practical use, this application, such as Figure 1As shown, a first water pump 5 can be installed at the outlet 20 of the water tank 2. The output end of the first water pump 5 is connected to an outlet pipe 6, and the other end of the outlet pipe 6 is connected to the vegetable cooling tank 9. In addition, the vegetable cooling tank 9 is provided with a suction port 90, and a second water pump 7 is installed at the suction port 90. The output end of the second water pump 7 is connected to a suction pipe 8, and the other end of the suction pipe 8 is connected to the inlet end 321 of the inlet end 32. This connection can also be made detachable using a detachable component 4.

[0033] In this application, the flow space in the heat exchange plate 1 is used for the flow of a refrigerant, which can be propylene glycol. The refrigerant enters from inlet 11 and flows downwards inside the heat exchange plate 1, filling the entire flow space, and finally flows out from outlet 12. The refrigerant continuously circulates. After flowing out from outlet 12, the refrigerant returns to the cooling device, which cools it down. The cooled refrigerant then re-enters the heat exchange plate 1 from inlet 11, thus continuing the circulation. The aforementioned cooling method and cooling device for the refrigerant are all prior art.

[0034] The purified water in the vegetable cooling tank 9 is drawn out by the second water pump 7 and sent into the water distribution pipe 30 through the water pumping pipe 8 and the water inlet 321. The water distribution holes 300 of the water distribution pipe 30 spray water out and onto the surface of the heat exchange plate 1. The water flows down along the surface of the heat exchange plate 1 and forms a water curtain. During the flow, the water and the refrigerant inside the heat exchange plate 1 transfer heat, which lowers the water temperature. The cooled water flows into the water tank 2, and then the first water pump 5 pumps the cooled purified water in the water tank 2 into the vegetable cooling tank 9 through the water outlet pipe 6, thus completing one heat exchange cycle.

[0035] Among them, such as Figure 3 As shown, the two ports 310 of the U-shaped end 31 are respectively connected to one end of the two water distribution pipes 30 to form a first connection part 33, and a gasket (not shown in the figure) is provided between each port 310 and the end of the water distribution pipe 30. The two connecting ends 320 of the water inlet end 32 are respectively connected to the other ends of the two water distribution pipes 30 to form a second connection part 34, and a gasket (not shown in the figure) is provided between each connecting end 320 and the other end of the water distribution pipe 30. This ensures the sealing of the connection. Additionally, as shown... Figure 4 and Figure 5As shown, the detachable component 4 in this application includes two semi-circular retaining rings 40 and a pin 41. The two retaining rings 40 are arranged opposite each other, with one end of each retaining ring 40 rotatably connected to the other. The other end of each retaining ring 40 is provided with a connector 42, and the connector 42 is provided with a connection hole 43. In actual use, the two retaining rings 40 are respectively fitted onto the outside of the first connecting part 33 or the second connecting part 34, and the connectors 42 of the two retaining rings 40 are arranged opposite each other. The pin 41 is inserted into the connection hole 43, thereby completing the clamping of the two retaining rings 40 onto the outer wall of the pipe at the connection point.

[0036] like Figure 2 As shown, multiple fixing plates 13 are welded to the top of the heat exchange plate 1. The fixing plates 13 are arranged at intervals along the top edge of the heat exchange plate 1. The fixing plates 13 are perpendicular to the plane of the heat exchange plate 1. There are mounting grooves 130 on both sides of the fixing plates 13, and the water distribution pipes 30 are placed in the mounting grooves 130.
