Abstract

A storage vessel includes a housing which has an inlet for introducing flowable particulate material into, and an outlet for withdrawing the same from the housing. At least one expandable cushion is located inside the housing and is operative for expanding and collapsing so as to agitate the material contained in the housing to thereby prevent agglomeration of the material. Air is introduced into the cushion to expand the same.
