Contact Shock Freezer for Plasma

The bag is in contact with the surfaces of the wells and intense extraction of thermal energy is obtained in this manner, minimizing the freezing time: <45 minutes for 24 or 48 [450 ml.] standard bags, with a net content of plasma of at least 230 cc’s and an initial temperature between +25°C and +30°C [KW conducted tests with bags with a mass of 260 gr. each].

An advantage is gained by storing the bags vertically while maintaining the freezing advantage of the typical horizontal solution.  The surface of the wells is smooth inox steel with no edges preventing accidental breaks caused by bumping of the bags.  Furthermore should any leak from the bags or moisture from condensation create the need for drainage each well has an outlet leading to a single external tube.


The storage solution in vertical encounters, in fact, all the freezing advantages of the horizontal freezers, leaving the vertical placement of the plasma bags salvaged.

The surface of the wells is smooth and in inox steel, without edges, and therefore permit the safe storage against accidental breaks or bumps of the bags; permits furthermore the eventual download of liquids exiting due to breakage, from the bottom, or the successive condensation to a freezing and maintenance stop, be means of outlets [one for each well], all gathered and l eading to a single external tube.
