ABSTRACT:
The machine of the invention comprises the following components interconnected through air conduits; a cage drum rotatably mounted in a housing, an air cleaner for intercepting mechanical impurities, an air cooler, an air heater with a steam heating element, an adsorber with respective inlet and outlet connections for steam admission and discharging a mixture of steam and adsorbed solvent. The machine comprises also a system of directional valves for changing the direction of air flow therethrough and a means for cooling and separating a mixture of condensates of steam and solvent, which is connected, through a device for condensate separation and discharge, to the outlet of the steam heating element of the air heater.
The inlet of steam heating element is connected to an outlet connection for discharging a mixture of steam and desorbed solvent vapors from the absorber. The amount of adsorbent contained in the adsorber and its adsorption capacity are so selected as to provide catching of the solvent vapors at the final stage of drying the textiles under process involving air circulation through the cage drum and the adsorber within one operating cycle of the machine.
