Abstract: An improved dry cleaning machine is disclosed, which comprises a rotating drum, at least one storage tank for a cleaning solvent used in the drum, a pump for circulating the solvent from the tank to the drum through a feed line including a lint collector, a solvent filtration unit including at least one filter through which the solvent may be passed downstream the lint collector, a solvent decoloration unit including a bed of activated carbon through which the solvent may also be passed whenever necessary, and a solvent distillation unit comprising a still, a condenser and a separator. The improvement consists of a regeneration unit incorporated into the machine and comprising a regeneration chamber in which the carbon used in the decoloration unit may be introduced, preheated and reactivated with live steam, whenever desired.

Abstract: There is described an apparatus for drying and cooling dry cleaned items and for recovering cleaning solvents therefrom, including a cleaning drum for receiving and treating the items with cleaning solvent, a circulating fan for drawing air through the drum, a heater for heating the air drawn through the drum during the drying cycle of the dry cleaning machine, a condenser for condensing solvent vapors entrained in the heated air during the drying cycle and a gas compresser to supply the heater and condenser with hot gas during the drying cycle of the apparatus. The compresser also supplies cold refrigerant to the condenser during the drying cycle. The compresser then supplies cold refrigerant both to the heater and the condenser during the cooling cycle of the apparatus.
