Abstract

1,032,967. Freeze drying. LEYBOLDHOCHVAKUUM-ANLAGEN G.m.b.H. April 3, 1964 [April 6, 1963], No. 13960/64. Heading F4G. [Also in Division A2] A method of freeze drying foodstuffs &c. comprises the steps of inserting open packaging receptacles 5 containing the foodstuffs 51 in a receiving chamber 4 having at least one wholly or partly open side, slidably mounting the chamber 4 on rails 2 in a vacuum drying chamber having radiation elements 3, in such a manner that foodstuff is screened from the effects of direct irradiation by said heating elements, and then sealing the dried foodstuff in the packaging receptacles. The chamber 4 may be provided with holes 43 of various shapes or an elongated opening (not shown) in a side thereof. The chamber 4 is divided into compartments by fixed or removable partitions. The walls of the receiving chamber and the partitions may be made of metal.
