Abstract

An installation for dehydrating products, the installation having an enclosure, a member for sucking out the air contained in the enclosure, and a container for products that is received inside the enclosure and that is provided with a top opening having an air- and water-permeable bottom of a cassette extending in register therewith. The cassette contains zeolites. A sealing gasket extends between a perimeter of the bottom of the cassette and an edge of the container, defining the opening.

• F26B 13/30 - Arrangements of devices using drying processes not involving heating for applying suction, e.g. through perforated rollers
• F26B 25/18 - Chambers, containers, receptacles of simple construction mainly open, e.g. dish, tray, pan

Abstract

The invention relates to a method for controlling a dehydration plant that comprises a housing (1) provided with a means (2, 3) for generating a vacuum and receiving at least one tray (8) of products to be dehydrated and at least one cassette (9) containing zeolites, wherein the method comprises the step of adjusting the vacuum generation rate on the basis of a temperature of the zeolites in order to maintain the same in the vicinity of an optimal adsorption temperature.
