Abstract

861,082. Drying by freezing. LEYBOLDHOCHVAKUUM - ANLAGEN G.m.b.H. March 19, 1959 [March 19, 1958], No. 9571/59. Class 34(2) Apparatus for drying substances, e.g. blood plasma, by freezing and subsequent sublimation comprises a casing 30 housing a chamber 11 which rotatably mounts a circular hollow rack 1 and is adapted for subjection to a high degree of vacuum by a diffusion pump 20 and an auxiliary pump 21. The rack, which embodies receptacles 2 for the spring-held reception of plasma containers 3, is mounted on a hollow shaft 5 divided so that heat-exchange fluid may be introduced to and taken from the rack interior through the shaft via pipes 15, 16 and a stationary housing 14. The chamber 11 has a glass-fronted door 29 and in operation freezing is effected by a fluid between -20 and -30‹C. flowing through the rotating rack around the plasma via the pipes and the shaft. Subsequently, a vacuum is induced in the chamber, a valve leading to a condenser 23 is opened and a hotter fluid above -0‹C. is passed through the rack via the pipes and shaft until drying is effected.
