Abstract
Method to condition water-swellable hydrocolloids for use in mechanical forming processes such as die molding or injection molding. To avoid long conditioning times at high temperature, the hydrocolloids are conditioned to the predetermined water content at ambient temperature and then rapidly heated, just before processing, in a gaseous stream loaded with water to the equilibrium conditions needed to maintain the predetermined water content of the hydrocolloids at the high process temperature of the mechanical forming.
