Abstract
Drying articles by displacement and/or solubilization of water with an organic solvent, by dipping the article into a body of solvent which is made effervescent, the said body of solvent being separated, except at the top and bottom thereof, from a non-effervescent body of solvent by means of a baffle wall which extends from a level above the bottom of the solvent container to substantially the surface level of solvent in the container, whereby a circulation of solvent is set up between the effervescent and non-effervescent bodies, and water is removed from the upper part of the non-effervescent body of solvent.
