Freezing and thawing method of freezing and thawing machine and freezing and thawing machine

Abstract

The invention discloses a freezing and thawing method of a freezing and thawing machine and the freezing and thawing machine. The freezing and thawing method comprises the steps of feeding, descending of a lifting plate layer, freezing or thawing and discharging. The freezing and thawing machine comprises a freezing and thawing cavity, a fixed plate layer, a lifting plate layer and a feeding and discharging trolley, the fixed plate layer is fixed in the freezing and thawing cavity, the lifting plate layer is arranged above the fixed plate layer and can ascend and descend relative to the fixed plate layer, the feeding and discharging trolley comprises a feeding and discharging frame, a push-pull mechanism, a clamping frame and an electromagnetic assembly, and the clamping frame is arranged on the feeding and discharging frame. The push-pull mechanism is used for driving the clamping frame to move back and forth on the feeding and discharging frame and the fixed plate layer, and an electromagnetic assembly is arranged between the push-pull mechanism and the clamping frame. According to the freezing and thawing method of the freezing and thawing machine and the freezing and thawing machine, automatic feeding, freezing, unfreezing, discharging and other processes of the freezing and thawing machine are achieved, the risk of low-temperature discharging to personnel is avoided, rapid connection and separation of the push-pull mechanism and the clamping frame are achieved through magnetic suction feeding and discharging, the overall production efficiency is improved, only the lifting plate layer needs to be operated to ascend and descend, the fixed plate layer does not need to ascend and descend, and the movement stroke of the plate layer is reduced.

Description

technical field [0001] The invention relates to freezing and thawing equipment, in particular to a freeze-thaw method for a freeze-thaw machine and the freeze-thaw machine. 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. The low-temperature refrigerator or barrel freeze-thaw system structure currently used has the following disadvantages: 1) The temperature uniformity of the material during the freeze-thaw process is poor; 2) The operation process requires more manual intervention; 3) The current process of freezing and thawing , unable to select the appropriate temperature according to the material, unable to monitor the data; 4) unable to accurately determine the relationship between the phase transition temperature of the biopharmaceutical material and the temperature change of...

Problems solved by technology

The low-temperature refrigerator or barrel freeze-thaw system structure currently used has the following disadvantages: 1) The temperature uniformity of the material during the freeze-thaw process is poor; 2) The operation process requires more manual intervention; 3) The current process of freezing and thawing , it is impossible to select the appropriate temperature according to the material, and it is impossible to monitor the data; 4) It is impossible to accurately determine the relationship between the phase transition temperature of biopharmaceutical materials and the temperature change of the surrounding environment, and there is no process record of the temperature curve, so the quality of the product cannot be guaranteed

Nowadays, there are also some freeze-thaw machines, but most of them are manually fed in and out, and the volume is large, which is inconvenient for mass production
