Its core principle is to utilize the high permeability and solubility of SC-CO2 to efficiently remove moisture or solvents in the material, while avoiding problems such as thermal damage, structural damage, or solvent residues that may be caused by traditional drying (such as hot air drying, vacuum drying); However, when the existing critical carbon dioxide drying device dries cells, the long drying time will cause the activity of the cells to decrease, and the short drying time will affect the drying effect; Therefore, a supercritical carbon dioxide drying equipment for protecting cytokine activity is proposed to solve the above problems.

[0026] The drying mechanism 10 includes a workbench 1001, a drying plate 1002, an air storage chamber 1003, a third solenoid valve 1004, and an air jet valve 1005. Among them, the drying plate 1002 is mounted on the surface of the workbench 1001, and a cavity is provided inside the workbench 1001. The bottom of the cavity is provided with an air storage chamber 1003. The third solenoid valve 1004 is mounted above the air storage chamber 1003, and the air jet valve 1005 is mounted on the third solenoid valve 1004. The drying plate 1002 is a honeycomb-shaped air-permeable structure, and the air storage chamber 1003 is connected to the air jet valve 1005 through the third solenoid valve 1004. During drying, the sealing cover 8 moves downward to cover the drying mechanism 10, and the spring 802 plays a role in shock absorption. The sealing cover 8 makes the cells form a relatively sealed space on the drying plate 1003. Carbon dioxide gas enters the spray head 904 through the second solenoid valve 902, and the carbon dioxide in the critical state is sprayed onto the surface of the cells to dry the surface of the cells.

[0028] The working process of this application is as follows: First, place the cells to be dried on the surface of the drying plate 1002. Both the first gas cylinder 2 and the second gas cylinder 3 store carbon dioxide. Open the ventilation valve 201, and the carbon dioxide gas inside the first gas cylinder 2 and the second gas cylinder 3 enters the booster pump 4 through the first air pipe 202 for pressurization. Then open the first solenoid valve 401, and the carbon dioxide enters the heating mechanism 5 for heating; When the carbon dioxide is heated in the heating mechanism 5, first, the carbon dioxide enters the inside of the heating pipe 503 through the first air inlet joint 504, and then the heating coil 502 is powered on, and the carbon dioxide gas is heated by electromagnetic heating. During the heating process, the first temperature sensor 506 senses the temperature of the carbon dioxide gas inside the heating pipe 503 in real time. After the heating is completed, the carbon dioxide gas is discharged from the first air outlet joint 505; Carbon dioxide gas enters the interior of the tee 507 through the first air outlet joint 505. A part of the carbon dioxide gas enters the spraying mechanism 9 through the first branch air pipe 508, and another part of the carbon dioxide gas enters the interior of the drying mechanism 10 through the second branch air pipe 509 and the second air inlet joint 510; First, the drying chamber 6 is a sealed space relative to the outside world to avoid the influence of external air on the drying effect. During drying, the sealing cover 8 moves up and down with the telescopic movement of the hydraulic telescopic rod 7. When drying, the sealing cover 8 moves down to cover the drying mechanism 10, and the spring 802 plays a role in shock absorption. The setting of the sealing cover 8 enables the cells to form a relatively sealed space on the drying plate 1003. Carbon dioxide gas enters the spray head 904 through the second solenoid valve 902, and the carbon dioxide in the critical state is sprayed onto the surface of the cells to dry the surface of the cells. At the same time, the carbon dioxide in the critical state passes through the gas storage chamber 1003 and the third solenoid valve 1004 and is sprayed from the bottom of the drying plate 1002 through the air jet valve 1005, so that the carbon dioxide in the critical state performs drying operations from the bottom of the cells. After drying, the carbon dioxide is recovered into the interior of the recovery bottle 12 through the second ventilation pipe 15 from the adsorption cover 11. At this time, the air pump 14 provides power for the adsorption cover 11. The above is the working principle of this cell factor activity protection type supercritical carbon dioxide drying equipment.
