Abstract
Improvements in freeze-drying devices, characterized in that these apparatuses consist of a body autoclave of transparent material, of the type comprising the plexiglas (methyl methacrylate), lucite and other analogues, within which the articles to be treated are arranged for dehydration, this body being coupled to a freezing chamber provided with double facing within which a circulation of alcohol at a temperature of about -70ºC obtained in a cooler equipment takes effect, producing the vacuum in the autoclave by pneumatic machine and providing the calorific effect inside it by means of infrared emission produced by externally located lamp, which reaches the interior of the apparatus by the permeability of its body, a thermometer suitable to be read from the outside being disposed inside the autoclave, and being optional the incorporation of such a thermostat that, having fixed the val ores limits of the temperature of the regime, determines the start-up and cessation of the same equipment annexes the autoclave in order to maintain this temperature.
