摘要： Process is provided for the preparation of pregelatinized starch and/or pregelatinized flour, comprising the steps of: providing an aqueous medium having a pH in the range of -1.0 to 7.5; mixing starch and/or flour with the aqueous medium to form a starch composition having a pH in the range of 2.0 to 7.9, wherein the starch composition has the aqueous medium as continuous phase and contains between 5 and 60 wt.%, expressed as percentage of dry matter on total weight of the starch composition, of particles of starch and/or flour; and pregelatinizing the starch composition, wherein said composition is heated using a drum dryer to form the pregelatinized starch and/or pregelatinized flour; wherein during the heating the starch composition is dried using the drum dryer.

摘要： The present invention relates to a process for forming cellulose fibers or film from dissolved cellulose. The process comprises the steps of: dissolving cellulose in an aqueous coagulation sodium salt solution to provide a cellulose spin dope; extruding the cellulose spin dope into a coagulation bath liquid comprising an aqueous coagulation sodium salt solution to provide cellulose fibers or film; withdrawing a portion of the coagulation bath comprising coagulation sodium salt and sodium hydroxide (NaOH); cooling the withdrawn portion of the coagulation bath to precipitate solid coagulation sodium salt to recover sodium hydroxide (NaOH) substantially free from the coagulation salt; and using at least a portion of the recovered sodium hydroxide (NaOH) in dissolving the cellulose to provide the cellulose spin dope.
