Detailed Implementation

[0026] like Figure 1 and Figure 2As shown, an intelligent frying temperature curve control system with adjustable flavor includes a temperature curve and a fryer 1. People create temperature curves corresponding to time and temperature according to different flavors of fried foods. The vertical axis of the temperature curve represents the temperature of the oil in the fryer 1, and the horizontal axis represents the time the food is immersed in the fryer 1. An induction coil 3 is fixed to the bottom surface of the fryer 1. A cooling layer 2 is also provided on the outer surface of the fryer 1. A return water pipe is connected to the upper part of the cooling layer 2, and a return water valve 7 is provided on the return water pipe. A water inlet pipe is connected to the lower part of the cooling layer 2, and a water inlet valve 8 is provided on the water inlet pipe. A temperature sensor 28 is provided in the middle of the fryer 1, and a liquid level sensor 27 is also provided at the bottom of the fryer 1.

[0027] The fryer 1 is equipped with an oil storage tank 9 at its bottom, and the fryer 1 and the oil storage tank 9 are connected by a pipe. A connecting valve 11 is installed on the pipe between the fryer 1 and the oil storage tank 9. The lower part of the oil storage tank 9 is connected to the upper part of the fryer 1 by a pipe. An oil pump 10 is also installed on the pipe between the oil storage tank 9 and the fryer 1. A medium-frequency current is passed through the induction coil 3 to heat the oil in the fryer 1. The temperature of the oil in the fryer 1 is detected by the temperature sensor 28, and the magnitude of the medium-frequency current passed through the induction coil 3 is controlled in real time. When it is necessary to cool down the oil in the fryer 1, the water inlet valve 8 and the water return valve 7 are activated simultaneously. When the valve is opened, cooling water enters the cooling layer 2 through the inlet valve 8 and then flows out of the cooling layer 2 through the return valve 7, cooling the oil in the fryer 1. At the same time, the oil pump 10 and the connecting valve 11 are opened, and the lower temperature oil in the oil storage tank 9 enters the fryer 1 through the oil pump 10, while the higher temperature oil in the fryer 1 enters the oil storage tank 9 through the connecting valve 11, which can quickly cool the oil in the fryer 1. The liquid level sensor 27 detects the liquid level of the oil in the fryer 1 and stabilizes the liquid level of the oil in the fryer 1 by controlling the opening and closing of the connecting valve 11.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fryer 1 is provided with a lid 4, which includes a movable part and a fixed part. The movable part and the fixed part of the lid 4 are hinged together. A lifting motor 6 is fixedly connected to the upper surface of the fixed part of the lid 4. A threaded column 21 is connected below the lifting motor 6. The threaded column 21 is located inside the fryer 1. A lifting screen 12 is provided on the surface of the threaded column 21. The threaded column 21 and the lifting screen 12 are engaged by threads. The lifting screen 12 has an opening at the top. A fixed screen cover 13 is fixedly connected to the opening of the lifting screen 12. The fixed screen cover 13 is semi-circular in shape. A protrusion 15 is fixedly connected to the upper surface of one end of the fixed screen cover 13. The protrusion 15 is arc-shaped. A connecting block 16 is fixedly connected to the upper surface of the other end of the fixed screen cover 13. A movable screen cover 14 is also provided above the fixed screen cover 13.

[0029] The lower surface of the movable screen cover 14 is provided with a groove, which is arc-shaped. The protrusion 15 is located in the groove on the lower surface of the movable screen cover 14. The end of the movable screen cover 14 has a notch, and an opening and closing rotating shaft 18 is provided in the notch. An opening and closing plate 19 is fixedly connected to the surface of the opening and closing rotating shaft 18. The opening and closing plate 19 is corner-shaped. Normally, the lower end of the corner of the opening and closing plate 19 abuts against the inner surface of the notch. An opening and closing column 20 is also fixedly connected to the side of the opening and closing plate 19. The end of the opening and closing column 20 is wedge-shaped, and a groove is opened on the surface of the opening and closing column 20. The groove on the surface of the opening and closing column 20 is annular.

[0030] The surface of the docking block 16 has a groove, and the inner wall of the groove has a corresponding recessed hole. The groove and recessed hole of the docking block 16 are provided with a locking post 29 and a spring 17.

[0031] A support plate 22 is fixed to the lower surface of the lifting screen 12. The support plates 22 are arranged in a cross pattern. The lower surface of the support plate 22 has a groove. The length of the groove of the support plate 22 is less than the diameter of the lifting screen 12. A slider 23 is provided in the groove of the support plate 22. A support rotation shaft 24 is provided on the lower surface of the slider 23. The lower surface of the threaded column 21 is also provided with a recess. A rotating cylinder 25 is provided in the recess of the threaded column 21. The rotating cylinder 25 can rotate in the recess of the threaded column 21. The rotating cylinder 25 is located below the lifting screen 12. A rotating cylinder rotation shaft 26 is also provided on the surface of the rotating cylinder 25. The rotating cylinder rotation shaft 26 is connected to the support rotation shaft 24 by a connecting rod.

[0032] The operator first opens the movable part of the pot lid 4, then places the food into the lifting screen 12. The support plate 22 supports the lifting screen 12 to prevent uneven weight distribution of the food, which could cause the lifting screen 12 to tilt. Then, the operator pushes the opening and closing plate 19 in the movable screen cover 14, causing the movable screen cover 14 to move in an arc along the protrusion 15 towards the docking block 16. Since the lower end of the corner of the opening and closing plate 19 abuts against the inner surface of the notch in the movable screen cover 14, the opening and closing plate 19 will not rotate around the opening and closing rotation axis 18. The opening and closing post 20 on the surface of the opening and closing plate 19 then enters... Within the groove of the connecting block 16, the locking post 29 within the recessed hole of the groove is squeezed by the opening and closing post 20. The compression spring 17 deforms and retracts into the recessed hole of the groove of the connecting block 16. When the annular groove on the surface of the opening and closing post 20 passes the surface of the locking post 29, the spring 17 returns to its original deformation, causing the locking post 29 to spring into the annular groove on the surface of the opening and closing post 20, locking the opening and closing post 20 and the movable screen cover 14. At this time, the movable screen cover 14 and the fixed screen cover 13 are in contact with each other, jointly sealing the opening above the lifting screen 12, thereby confining the food within the lifting screen 12.

[0033] Subsequently, the lifting motor 6 starts, the threaded column 21 rotates in a certain direction, the lifting screen 12 engages with the threaded column 21, the lifting screen 12 descends, and the slider 23 moves along the groove on the lower surface of the support plate 22 toward the edge of the lifting screen 12. When the slider 23 is at the end of the groove on the lower surface of the support plate 22, the slider 23 stops moving. At this time, the lifting screen 12 is completely submerged in the oil in the fryer 1, and the lifting screen 12 also stops descending. Since the slider 23 and the rotating shaft 26 of the rotating drum are connected by a connecting rod, after the lifting screen 12 stops descending, the lifting screen 12 will rotate with the threaded column 21, and the food in the lifting screen 12 will also rotate with the lifting screen 12. The lower end of the threaded column 21 is also fixed with a paddle 30, which rotates with the threaded column 21 and tumbles the oil in the fryer 1, making the oil in the fryer 1 heat up and cool down more evenly, and also making the food in the lifting screen 12 fry more evenly. The fryer 1 is also connected to a smoke exhaust pipe 5, which is used to exhaust the smoke emitted by the food in the lifting screen 12 during frying.

[0034] When the lifting motor 6 starts rotating in the opposite direction, the lifting screen 12 will rise through the threaded engagement of the threaded column 21. The slider 23 will move along the groove on the lower surface of the support plate 22 toward the center of the lifting screen 12. When the slider 23 moves to the surface of the threaded column 21, the slider 23 will stop moving, and the lifting screen 12 will also stop rising. The lifting motor 6 will be turned off. At this time, the lifting screen 12 is completely detached from the oil in the fryer 1. By driving the lifting screen 12 to rise and fall through the lifting motor 6, the frying time of the food in the lifting screen 12 can be controlled. According to the temperature curve of the corresponding food, fried foods with different flavors can be made.

[0035] When the food is fried, the lifting screen 12 rises to its highest point and stops rotating. The operator rotates the opening and closing plate 19, causing the opening and closing column 20 to rotate out from above the groove of the docking block 16. Then, the operator pushes the opening and closing plate 19 in the opposite direction, causing the movable screen cover 14 to move in the opposite arc along the protrusion 15, thereby opening the opening above the lifting screen 12. The operator then removes the fried food.
