Abstract

926,174. Preserving food; freeze drying. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 18, 1959 [Aug. 22, 1958], No. 27044/58. Class 49. [Also in Group XIII] Foodstuffs are dried, or pre-frozen foods freeze-dried, by being interposed, under reduced ambient pressure, between layers of hotexpanded metal A multi-sandwich system in a vacuum chamber 1 comprises heating plates 5 between which are removable trays 17, with lids 21, containing the foodstuff 18 sandwiched between expanded metal layers 19, 20 which allow withdrawal of water vapour, after which the food is maintained in an atmosphere of inert gas until packed in an oxygen- and moisture-proof container. The metal layers 19, 20 may be electrical heating elements and plates 5 dispensed with. Controlled pressure may be applied to the multi-sandwich system by an hydraulically-operated pressure plate 14 cooperating with a fixed plate 13.
