Freezing and thawing machine for freezing and thawing process treatment of biopharmaceutical material

Abstract

The invention relates to a freezing and thawing machine for freezing and thawing process treatment of biopharmaceutical material and belongs to the technical field of bioengineering pharmaceutical equipment. The freezing and thawing machine comprises partition boards, a guide rod, a hanger rod, a support frame and a driving mechanism; the partition boards are horizontally arranged in the freezingand thawing machine layer by layer; heat conducting media are arranged in the partition boards; the guide rod is arranged on the side face of the partition boards; the hanger rod for limiting is arranged between the partition boards corresponding to each other up and down; the driving mechanism is arranged above the partition board on the uppermost layer and enables the upper and lower surfaces ofthe partition boards moving relatively to be in full contact with biological material to realize the purpose of fast freezing and thawing; the partition boards ensure uniform and consistent temperature during the freezing and thawing process, so that the problem that the existing biopharmaceutical material is not synchronous or uniform in temperature treatment during the freezing and thawing process is avoided, the problems that the existing biopharmaceutical material is not recorded during the freezing and thawing process, the uniformity is poor during the freezing or thawing process and theproduction efficiency is low are solved, and the retention period of the finished product of the biopharmaceutical material is prolonged.

Description

technical field [0001] The invention relates to a freeze-thaw machine used for freezing and thawing process of biopharmaceutical materials, belonging to the technical field of bioengineering pharmaceutical equipment. Background technique [0002] At present, most domestic biopharmaceutical companies and scientific research institutions use traditional low-temperature refrigerators and barrel freeze-thaw systems to freeze and thaw biopharmaceutical materials. Put the barrel-shaped container or regular container containing biopharmaceutical materials into a low-temperature refrigerator for freezing. The low-temperature refrigerator freezes to obtain low-temperature air by accelerating the heat exchange between air and refrigerant inside the refrigerator, and blows it through forced convection of low-temperature air. To achieve the purpose of rapid freezing of the working area; or to directly put biopharmaceutical materials into the barrel heat exchanger for freezing or thawing...
