Abstract
1,030,814. Packaging. LEYBOLD HOCHVAKUUM-ANLAGEN G.m.b.H. April 3, 1964 [April 6, 1963], No. 13959/64. Heading B8C. [Also in Divisions A2 and F4] A method of freeze drying footstuffs or other material comprises passing the material in pockets provided on sheets made of foil material (e.g. aluminium) through a vacuum drying chamber and sealing the pockets after the material has been dried but before leaving the drying plant. As shown, material in pockets 5 in sheets 2 is passed between heating plates 7 from entry gas lock 9 through drying chamber 95 and outlet gas lock 91 and into sealing chamber 92. The drying chamber 95 may be separated from locks 9 and 91 by sliding partitions 8 and 81 respectively. When outlet lock 91 is fully charged with sheets 2, it is sealed from drying chamber 95. The sealing chamber 92 is reduced to atmospheric pressure by flushing with nitrogen and the pocketed sheets are closed by sealing thereon sheets 94 by sealing press 921. The closed pockets are stored in chamber 93 which also stores sheets 94. The sheets 2 may be perforated and conveyed through the plant by driving rollers, pinions or racks. In Fig. 5 (not shown), foil 23 is provided with pockets 5 having sealing flaps 941. The foils 23 are suspended from a conveyer and passed between vertical heating plates 7. The sheets may be provided with perforations to allow the sealed pockets to be easily separated.
