Abstract

1370683 Freeze drying ATLAS AS 23 Aug 1971 [25 Aug 1970] 39369/71 Heading F4G Trays 5 containing material to be dried are pushed by a cylinder 8 one at a time into a vacuum lock 7, carried on a support 12 into a vacuum chamber 1, raised by a lift 13 and bands 15 to form a stack, pushed by a cylinder device 16, 17 and then by successive stacks of trays 5 along rails 4 and between heater plates 3, lowered by further bands 15 and a further lift 13, carried on a further support 12 one at a time into a vacuum lock 18 and discharged by a cylinder 19. Each vacuum lock 7 and 18 comprises flaps 36 and 40 operable by hydraulic piston-andcylinders 37 and 41. Each vacuum lock 7 and 18 is connected to a vacuum pump independent of the vacuum pump for the chamber 1, and is connected by a valved conduit to the chamber 1 or the suction conduit thereof. Water vapour from the chamber 1 is condensed by one or the other of tubes 23 or 24 a heated tube 33 being provided to defrost the condenser tube not in use. A heating medium is circulated through ducts formed in the heater plates 3 under the control of a thermostatically-operated valve. The movements of the trays are controlled by contact thereof with switches, e.g. 64, 68 pressure-switches, and timers. The heater plates 3 are supported in separate sets which may be heated to different temperatures.
