发明名称 Method of drying a material having a cohesive phase
摘要 A method for drying a material such as a polymer hydrogel which passes through a cohesive phase as it dries is disclosed. The method comprises agitating a composition while removing liquid until the solids content of the composition reaches a level at which the composition enters a cohesive phase, halting agitation, removing liquid from the composition in the absence of agitation, and resuming agitation. Practice of the present invention can eliminate the problems associated with adhesion of a material to itself and to process equipment during the cohesive phase.
