THE FREEZE-DRIER: OPERATING SAFETY AND OPTIMIZATION OF ENERGY CONSUMPTION.

LYOPHILISATEUR : SECURITE DE FONCTIONNEMENT ET OPTIMISATION DE LA CONSOMMATION ENERGETIQUE.

Author(s) : LARRAT P.

Summary

AMONG THE CRITERIA WHICH A PRODUCTION-SCALE FREEZE-DRIER MUST SATISFY,OPERATING SAFETY AND LOW ENERGY CONSUMPTION MUST BE GIVEN PARTICULAR EMPHASIS. AS FAR AS SAFETY IS CONCERNED, IT APPEARS PREFERABLE TO HAVE A NUMBER OF PRINCIPAL COMPONENTS (COMPRESSORS, PUMPS, ETC), EACH ONE BEING USED IN A SPECIFIC CIRCUIT, INDEPENDENT OF OTHER CIRCUITS, RATHER THAN USING A SINGLE, HIGHER-POWERED COMPONENT. AS THESE COMPONENTS ARE CONTROLLED BY A MICROCOMPUTER, THE WAY EACH OF THESE COMPONENTS OPERATE CAN BE MONITORED AND CONTROLLED ON THE BASIS OF REAL NEEDS IN ORDER TO OPTIMISE ENERGY CONSUMPTION. THIS MEANS THAT A POWER RESERVE WOULD BE AVAILABLE ALMOST IMMEDIATELY, IF A PARTICULAR NEED ARISES, EITHER BECAUSE OF AN UNEXPECTED INCREASE IN DEMAND OR AS A RESULT OF FAULTY OPERATION BY ONE OF THE BASIC COMPONENTS. WITH THIS SAME SOFTWARE, PERFORMANCE TESTS ON THE MACHINE CAN BE CARRIED OUT, TO SUPPLY USEFUL INFORMATION ON THE STATE OF THE MACHINE AND ITS EVOLUTION.
