ABSTRACT:
Apparatus and method for reducing the concentration of solvent vapor in the drum of a drycleaning machine upon completion of a cleaning and drying operation, during which articles are cleaned in the drycleaning machine, the drycleaning machine being of the type having a drum, and a solvent recovery system communicating with the drum for recovering solvent from solvent-laden air circulated through the solvent recovery system and the drum during a drying and solvent recovery cycle, the apparatus and method including an arrangement for circulating solvent-laden air from the drum through the solvent recovery system during the drying and recovery cycle, and closing communication between the drum and the solvent recovery system during a post-recovery cycle, subsequent to the drying and recovery cycle, and then circulating solvent-laden air from the drum through an adsorption unit during the post-recovery cycle to reduce the concentration of solvent vapor in the drum to an acceptable level prior to accessing the drum for removal of the cleaned articles.
