Plasma flat plate instant freezer

Abstract

The invention discloses a plasma flat plate instant freezer which comprises an upper cooling plate and a lower cooling plate. The lower cooling plate is fixed at the upper end of a body frame part. A lifting mechanism is fixed on the body frame part. An upper lifting frame of the lifting mechanism corresponds to the lower cooling plate. The upper cooling plate is hung on the bottom face of the upper lifting frame. A pressure adjustable mechanism is arranged between the upper cooling plate and the four corners of the upper lifting frame. The hung upper cooling plate structure is used, the pressure of the upper cooling plate structure has certain floating amount, so that during the process that the upper cooling plate goes down and presses a plasma bag with the lower cooling plate, when blood bags of the same specification have tiny difference, through a floating structure of an upper cooling plate component, even force is exerted between a lower cooling plate component and the upper cooling plate component, and the fact that each plasma bag is pressed reliably is guaranteed.

Description

technical field [0001] The invention belongs to the field of refrigerating equipment, and in particular relates to a plasma plate quick-freezing machine. Background technique [0002] At present, the opening and closing device of the cold plate of the flat-panel plasma quick-freezing machine adopts the upper cold plate to be fixed, and the lower cold plate to move vertically up and down, so that the lower cold plate and the upper cold plate clamp the plasma bag and directly contact the conduction surface. The rapid freezing method enables the plasma to be quickly frozen and formed in a short period of time, which minimizes the impact of too long freezing time on the quality of the plasma. The lower cold plate moves downward to form a space for placing and taking out the plasma bag with the upper cold plate, and the lower cold plate moves upward together with the upper cold plate to compress the plasma bag to achieve direct surface contact with the quick-frozen plasma. The d...

AI Technical Summary

Problems solved by technology

The device has the following defects (1) The plasma bag is placed on the lower cold plate, and the energy consumption of moving the lower cold plate is large; (2) The distance between the lower cold plate and the upper cold plate is fixed after the lower cold plate is moved, when the capacity of the same specification blood bag is different , the force on the plasma bag is uneven
