Abstract

The invention discloses a screw rod platform of a freezing and thawing machine clamping device. The screw rod platform comprises screw rod nut drive blocks, screw rods, screw rod bearing shafts, drive mechanism connecting assemblies, bevel gear pairs, couplings, a drive rod, freezing liquid fixing parts and screw rod fixing parts. The screw rod platform of the freezing and thawing machine clamping device is connected with drive equipment through the drive mechanism connecting assemblies, the drive equipment is used for driving gears, the couplings and the drive rod to drive up-down screw rod nuts to move back and forth on the screw rods, protein liquid compression is achieved, the moving stroke of the screw rods can be controlled according to the freezing time effect of protein liquid, and thus the problems of clamping thickness uniformity and thickness controllability in the freezing process of the protein liquid are effectively solved; and the freezing time is shortened, the size after freezing is decreased, storage is facilitated, and hence cell integrity after freezing of the protein liquid can be guaranteed more perfectly.

Description

technical field [0001] The invention relates to a pharmaceutical equipment, in particular to a screw platform for a clamping device of a freeze-thaw machine. Background technique [0002] Freeze-thawing of protein products in currently known biopharmaceuticals is to use refrigeration equipment to freeze products at low temperatures to -15°C to -20°C, and then utilize other heating equipment to thaw the products. The traditional freezing process is very easy to cause inhomogeneity of the product. The protein concentration of the product frozen at different stages varies greatly, which can reach more than 10 times. Irreversible polymerization or denaturation, resulting in reduced product purity. At present, there is no special device on the market that is specifically aimed at the technical requirements of the freezing process in freezing and thawing, can realize quantitative clamping and compression, and is convenient for automation. Contents of the invention [0003] The...
