ABSTRACT:
A colloidal substance is injected into a vacuum chamber to be dehydrated therein. The dehydrated substance is extracted from the vacuum chamber by a screw extruder disposed at a bottom of the vacuum chamber. A gas resulting from the dehydration is drawn from the vacuum chamber into a surface condenser to be cooled through an indirect heat exchange with cooling water. After the dehydration of the substance, the extraction of the dehydrated substance and the cooling of the gas are carried out in parallel.
