[0040] The vacuum pump 7 in the present invention is an existing disclosed technology, and the selected model is CQB-412.

[0041] The working principle and use process of the present invention are as follows: first, the control box on one side of the sealed box 3 of the present invention is adjusted, and the control box controls the manipulator to drive the sealing cover 4 to move. After the sealing cover 4 moves, the food is added to the inside of the frying chamber 2 in the sealed box 3, and then the sealing cover 4 is closed again and the vacuum pump 7 is turned on. The vacuum pump 7 starts to extract the air in the sealed box 3 along the air guide pipe 6. During the vacuuming process, the condenser tube dissipates heat and cools the air guide pipe 6 to prevent damage to the equipment caused by excessive temperature. During the process of vacuuming the sealed box 3, the oil pipe 81 connected to its bottom end sucks the grease in the oil storage tank 87 into the inside of the sealed box 3 due to pressure changes. When the grease covers the top of the food in the frying chamber 2, the vacuum pump 7 and the oil pipe 81 are turned off, and then the heating wire 5 is started to heat the oil in the sealed box 3. After the grease is heated, the food is fried. During the frying process, the stepper motor is mobilized The frying chamber 2 rotates to heat the food evenly. After the frying of the food is completed, the sealing box 3 is first inflated to ensure that the pressure returns to normal, and then the oil pipe 81 is opened to allow the grease to flow into the oil storage tank 87. The food residue is blocked and collected by the impurity removal chamber 83 when it flows into the oil storage tank 87. The flow of grease drives the buffer spring 82 to vibrate, ensuring that the residue in the impurity removal chamber 83 can shake off the oil. After the grease has flowed out, the control box is started to control the manipulator to open the sealing cover 4, and then the frying chamber 2 is taken out by the manipulator and the food is poured into the storage chamber 14. When the food enters the storage chamber 14, the water pump 17 is started to pump out the water in the cooling water tank 16. The water flows along the circulating water pipe 15 into the heat dissipation chamber 12 and circulates to dissipate heat when it is full. The residual grease in the food is adsorbed by the oil absorption plate 19. After the food is cooled, the unloading baffle 11 can be opened along the hinge to unload the food.
