Document Type and Number:
Japanese Patent JPS62502058
Kind Code:
A
Abstract:
A method and apparatus for freeze drying heat sensitive aqueous products on a continuous basis, utilizing molecular sieves to sequester the sublimating water vapor, is described. At least two beds of sieve are used sequentially, one being heat regenerated while another is actively adsorbing condensable vapors. Exotherm is controlled during freeze drying, and bed regeneration may be accomplished without the use of a purge gas. The advantages of certain types and sizes of molecular sieves, in a continuous freeze drying procedure, is discussed.
