[0020] like Figure 1 and Figure 2 As shown, the manual reversing valve 3 is a two-position three-way manual reversing valve.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the first electromagnetic reversing valve 4 and the second electromagnetic reversing valve 5 are both two-position five-way valves.

[0022] The working principle of the lifting control system of a plasma quick freezing machine described in the present invention is as follows:

[0023] When there is electricity, the control method is as follows: when the first solenoid reversing valve 4 is energized and the second solenoid reversing valve 5 is not energized, the first solenoid reversing valve inlet 4P and the first solenoid reversing valve outlet Ⅱ4B are connected, and the pressurized gas flows to the second solenoid reversing valve inlet 5P through the first solenoid reversing valve outlet Ⅱ4B. At this time, the second solenoid reversing valve inlet 5P is connected to the second solenoid reversing valve outlet Ⅰ5A, and the pressurized gas flows to the rodless chamber of the first cylinder 6 and the second cylinder 7 through the second solenoid reversing valve outlet Ⅰ5A, and the cylinder is pushed upward. At the same time, the gas in the rod chamber of the cylinder flows to the second solenoid reversing valve outlet Ⅱ5B, and then is discharged from the second solenoid reversing valve exhaust port Ⅱ5S. In addition, the rising speed can be controlled by the first manual speed regulating valve 10 and the second manual speed regulating valve 11; when the first solenoid reversing valve 4 and the second solenoid reversing valve 5 are energized at the same time, the first solenoid reversing valve 4 and the second solenoid reversing valve 5 are energized at the same time. An electromagnetic reversing valve inlet 4P is connected to a first electromagnetic reversing valve outlet Ⅱ4B, and pressurized gas flows to a second electromagnetic reversing valve inlet 5P through the first electromagnetic reversing valve outlet Ⅱ4B. At this time, the second electromagnetic reversing valve inlet 5P is connected to a second electromagnetic reversing valve outlet Ⅱ5B, and pressurized gas flows to the rod chambers of the first cylinder 6 and the second cylinder 7 through the second electromagnetic reversing valve outlet Ⅱ5B, and the cylinders retract downward. At the same time, the gas in the rodless chambers of the cylinders flows to the second electromagnetic reversing valve outlet Ⅰ5A, and then is discharged from the second electromagnetic reversing valve exhaust port Ⅰ5R. In addition, the descending speed can be controlled by the third manual speed regulating valve 12 and the fourth manual speed regulating valve 13; when the first electromagnetic reversing valve 4 and the second electromagnetic reversing valve 5 are not energized, under the action of the first one-way valve 8 and the second one-way valve 9, the gas in the cylinder cannot overflow, and the upper and lower cold plates remain stationary.

[0024] In case of power failure, the control method is: press the manual reversing valve 3 and keep it stationary, the manual reversing valve air inlet 3P and the manual reversing valve air outlet 3A are connected, and the pressurized gas in the gas storage tank 2 flows to the rodless chamber of the first cylinder 6 and the second cylinder 7 through the manual reversing valve air outlet 3A, and the cylinder is pushed upward, so the upper cold plate rises, and the manual reversing valve 3 is released, and the upper cold plate is locked.
