Method for drying polymer hydrogel

摘要

In a method for drying a hydrogel of polymers, the gel is extruded through a perforated plate with shearing forces applied traversely along a surface of the perforated plate. The polymer gel thus formed into aggregates, cut into series of globules and then stuck together into a plurality of masses of strand-like configuration which are then dried out by hot air under the application of shearing forces, so that the strand-like aggregates are separated into individual globules whereby further drying and grinding is made possible.
