Abstract
A method and a device for drying machine parts, e.g. balls or rolls for roller bearings, upon washing the parts in a washing liquid containing a solvent, especially a polluting solvent. Upon washing, the wet parts are fed into a chamber, and a dry, hot gas is injected into the chamber and evacuated therefrom. The evacuated humid gas is recirculated in a circuit and, upon being compressed and cooled, the gas is freed from its solvent contents in a liquid separator and is heated before re-injection into the chamber. A reduced gas pressure is maintained in the chamber by controlling the gas flow in the recirculation circuit, and the gas in the chamber is cooled, so that the partial pressure of the solvent in the chamber is substantially reduced.
