NOVEL METHOD OF DEHYDRATION OF SUBSTANCES BY SOLVENT EXTRACTION AND NOVEL METHOD OF SOLVENT RECOVERY BY RADIO FREQUENCY / MICROWAVE ASSISTED HEATING

摘要

A process of dehydration of substrates by using volatile solvents. An object of this invention is to propose a new process for dehydration of substrates by solvent extraction. The residual solvent remaining in the substrate is then recovered using radiofrequency and microwave assisted heating mechanism. This invention helps recover the solvent without any loss of solvent and renders the substrate completely dry.
