Then, the on-off valve 31 of the exhaust pipe 30 communicating with the bottom of the washing and drying tank 1 is opened, and the vacuum pump is opened.
Drive 32. The cleaning and drying tank 1 is driven by the driving of the vacuum pump 32.
The vacuum inside is reduced to about 5 torr. As the degree of vacuum in the washing and drying tank 1 progresses, the residual solvent humidified by the hot air in the previous drying step is evaporated and vaporized, and the vaporized solvent is cooled by the cooler 27 to be condensed and liquefied. The liquid is collected in the cleaning solution tank 2 from the drain pipe 29 of the duct 25. By this vacuum drying process, in particular, the solvent remaining in the gap between the objects to be cleaned of the small articles stored in the stack,
Alternatively, the solvent remaining in the deep hole or the like of the object to be cleaned is recovered.
