Abstract

The insert container (1) for freeze-drying plants comprises a plurality of vertical ribs (4) subdividing the insert container (1) into parallel compartments (7). Vapor-pervious tubes (5) extend transversely of and traverse the ribs (4) preferably at about one-third of their height. The tubes (5) communicate with the ambient atmosphere through one or more vapor discharge channels (6) extending parallel to the ribs (4). The water vapor can also be discharged through channels (12) formed between the side walls (3) of adjacent insert containers (1).
