Cytokine sterile freeze-drying preservation equipment

Abstract

The invention discloses cytokine sterile freeze-drying preservation equipment in the technical field of cytokine sterile freeze-drying preservation. The cytokine sterile freeze-drying preservation equipment comprises a motor, a refrigerator and a transparent cylindrical shell, the refrigerator is fixedly arranged on the inner wall of the bottom end of the shell, the side wall of the shell is provided with an inlet and outlet pipe orifice, and the edge of the inlet and outlet pipe orifice is hinged with two symmetrical rotating plates; and a storage mechanism, a rail mechanism and a lifting mechanism are included, the storage mechanism is rotatably arranged in the center of the shell, the rail mechanism is rotatably connected to the upper end of the storage mechanism, and the lifting mechanism is fixedly arranged on the lower end face of the rail mechanism. The problem that multiple cytokines are placed in a mixed manner, the interior of an incubator is directly operated with the hand,and the pollution among various cytokines is possibly caused while the cryopreservation effect of other freeze-drying bottles is easily influenced is solved.

Description

technical field [0001] The invention relates to the field of aseptic freeze-drying preservation of cytokines, in particular to a device for aseptic freeze-drying preservation of cytokines. Background technique [0002] Freeze-drying technology is to dry frozen products under low-temperature vacuum. After drying, the volume and shape of the product basically remain unchanged, and it is sponge-like without drying shrinkage; it can quickly return to its original shape when rehydrated. Freeze-drying technology can remove more than 90% of the moisture in the material, and the dried product has a long shelf life, and can be stored at room temperature in the dark or in a 4°C refrigerator for a long time during storage, without expensive low-temperature storage equipment and complex storage conditions; and during transportation because of its light weight, it is convenient for long-distance transportation. [0003] However, the currently dried cytokines need to be packed in air-per...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of aseptic freeze-drying storage equipment for cytokines, to solve the problem that the currently dried cytokines proposed in the above background technology need to be packed in a gas-permeable container, and then stored, but the existing cytokines have no In order to improve the work efficiency, the bacteria freeze-drying storage device will have multiple incubators in the storage device, and the incubators are folded vertically for storage, which will make it inconvenient to take the cytokines in the bottom incubator when it is taken. , has brought a lot of trouble to the experimenters; usually a variety of cytokines are mixed in an incubator, and the interior of the incubator is directly operated by hand, which is easy to affect the cryopreservation effect of other freeze-drying bottles and may cause Contamination problems between cytokines
