The vacuum pump 10 is connected to the inner space of the frying box 3 through an air guide pipe 34, the vacuum pump 10 is used to form a vacuum state inside the frying box 3, and the oil tank 4 is used to provide oil.

[0024] A filter screen 41 is provided inside the oil tank 4, and the filter screen 41 is used to filter impurities in the oil. The frying box 3 is connected to the oil tank 4 through an oil outlet pipe 32 and an oil return pipe 33. One end of the oil outlet pipe 32 is connected to the top of the filter screen 41, and the other end of the oil outlet pipe 32 is connected to the bottom of the frying box 3. One end of the oil return pipe 33 is connected to the bottom of the filter screen 41, and one end of the oil return pipe 33 is connected to the side wall of the frying box 3. An oil pump is provided on the oil return pipe 33, and the oil inside the frying box 3 can enter the oil tank 4 through the oil outlet pipe 32, and after passing through the filter screen 41, enter the frying box 3 through the oil return pipe 33.

[0025] refer to Figure 1 An opening is arranged at the top of the frying box 3, and a cover plate 6 for sealing the opening is arranged at the opening. Connecting blocks 61 are arranged on both sides of the cover plate 6. The connecting blocks 61 are connected to the supporting frame 2 through a supporting cylinder 8 vertically arranged along the axis. The supporting cylinder 8 realizes the vertical movement of the cover plate 6 by telescoping, thereby completing the contact sealing and separation between the cover plate 6 and the frying box 3.

[0026] Furthermore, a connecting bracket 7 rotatably connected to the cover plate 6 is provided at the bottom of the cover plate 6, and a rotating motor 9 for driving the connecting bracket 7 to rotate is provided at the top of the cover plate 6, and the connecting bracket 7 is used to install the frying net trough 5. The frying net trough 5 is a mesh frame, and the inside of the frying net trough 5 is used to place bean products.

[0027] refer to Figure 2 Two connecting plates 71 are arranged at the lower part of the connecting bracket 7, and the two connecting plates 71 are arranged in parallel, and the frying net slot 5 can be installed between the two connecting plates 71. Specifically, the opposite surfaces of the two connecting plates 71 are respectively provided with slide grooves 72, and the opening of the frying net slot 5 is provided with a connecting frame 51, and the two sides of the connecting frame 51 match the slide grooves 72.
