[0020] By adopting the above technical solution, the heat exchange plate is a pillow-type heat exchange plate, so that it is not easy to adhere to edible oil.
[0021] In some embodiments, the heat exchange assembly further includes a first header and a second header, the first header and the second header are spaced apart on both sides of the heat exchange barrel along the first direction, wherein the first header is communicated with the cooling medium inlet of the heat exchange plate, and the second header is communicated with the cooling medium outlet of the heat exchange plate.

Figure 1 .
[0039] In some embodiments, the edible oil heat exchanger includes: a heat exchange barrel 10 , a heat exchange component 20 and a foaming mechanism 30 .
[0040] The heat exchange barrel 10 has a heat exchange chamber 11, which can be filled with edible oil; the heat exchange component 20 includes a plurality of heat exchange plates 21 located in the heat exchange chamber 11, wherein the heat exchange plates 21 are hollow structures so that the heat exchange plates 21 can accommodate heat exchange medium; the bubbling mechanism 30 includes an air pipe 31 passing through the heat exchange chamber 11 along a first direction and an air inlet 32 located on one side of the heat exchange barrel 10 along the first direction, the air pipe 31 is connected to the air inlet 32, wherein the air pipe 31 is provided with a plurality of air holes 33 at intervals along the first direction.
[0041] In the embodiment of the present application, edible oil can be filled in the heat exchange chamber 11, so that the edible oil can fully contact the heat exchange plate 21 located in the heat exchange chamber 11, wherein the heat exchange plate 21 can accommodate the heat exchange medium, so that the heat exchange medium can exchange heat with the edible oil through the wall of the heat exchange plate 21.
[0042] Exemplarily, the air holes 33 are circumferentially arranged on the air pipe 31, wherein the air pipe 31 is located in the middle of the heat exchange chamber 11. The air pipe 31 is located at the center of the heat exchange chamber 11 so that the gas can be fully diffused into the heat exchange chamber 11 and fully contact with the edible oil. When the air pipe 31 is filled with gas through the air inlet 32, the gas will overflow along the air holes 33 distributed on the air pipe 31 and mix into the edible oil in the heat exchange chamber 11. When the amount of gas is large, the edible oil can be in a state similar to boiling, which accelerates the mixing of the edible oil and makes the heat distribution more uniform, thereby improving the heat exchange efficiency.
[0043] In some embodiments, the heat exchange barrel 10 further includes an edible oil inlet 12 and an edible oil outlet 13, which are in communication with the heat exchange chamber 11, wherein the edible oil inlet 12 is located at the top of the heat exchange barrel 10 along the first direction, and the edible oil outlet 13 is located at the bottom of the heat exchange barrel 10 along the first direction, so that the edible oil can effectively use gravity to assist its flow.

Preferably, nitrogen, which has a large reserve and low price, can also be used to effectively stir and mix the edible oil.
[0051] See also Figures 4 to 5 As shown, Figure 4 A schematic structural diagram of an embodiment of a heat exchange plate 21 of an edible oil heat exchanger provided by the present application is shown; Figure 5 The internal structure of an embodiment of an edible oil heat exchanger provided by the present application is shown in FIG. Figure 2 .

[0055] In the embodiment of the present application, the cooling medium (e.g., cooling water) is smoothly circulated by the pipeline design of distributing the cooling medium through the first header 22 and collecting the cooling medium through the second header 23. For example, the cooling medium enters the first header 22 along the cooling medium main inlet 14, flows into the heat exchange plate 21 through the cooling medium inlet 210 of the heat exchange plate 21, and fully exchanges heat with the edible oil through the wall of the heat exchange plate 21, and flows out from the cooling medium main outlet 15 along the cooling medium outlet 220 of the heat exchange plate 21 after being collected through the second header 23.
[0056] The heat exchange component 20 is also provided with an external driving pump body to drive the cooling medium to flow along the bottom of the heat exchange barrel 10 to the top of the heat exchange barrel 10, so as to control the flow rate of the cooling medium and improve the heat exchange effect.

[0058] In some embodiments, the heat exchange assembly 20 further includes a plurality of distance bars 24 spaced apart along a first direction, the distance bars 24 being located between the air pipe 31 and the heat exchange plate 21, wherein a groove 240 for clamping the heat exchange plate 21 is provided on the side of the distance bar 24 facing the heat exchange plate 21, wherein the air pipe 31 is located at the center of the distance bar 24.
[0059] In the embodiment of the present application, distance bars 24 are provided to fix and install a plurality of heat exchange plates 21. Since the heat exchange plates 21 extend along the first direction, the provision of a plurality of distance bars 24 can effectively improve the stability of the heat exchange plates 21, wherein the notches 240 of the distance bars 24 can clamp the heat exchange plates 21 and determine the distance between two adjacent heat exchange plates 21.
