PROCESS FOR PREPARING STARCH MICROGEL PARTICLES FOR THE PAPER INDUSTRY AND USE OF A DEVICE FOR PRODUCING THE SAME

摘要

A process for making starch or polysaccharide particles in a micro fluidic reactor, comprising at least two immiscible liquid inlet streams, in which process the two liquid streams are forced through a plurality of adjacent micro channels of the micro fluidic reactor and joined together to form an outlet stream of a water- in-oil (w/o) emulsion system, where the discontinuous phase will be a mixture based on aqueous starch or polysaccharide and a continuous phase will be an oil/solvent based system and wherein a polyvinyl alcohol with a molecular weight of between 5.000 and 140.000, preferably between 5.000 and 30.000 is added to the mixture based on starch or polysaccharide. Furthermore the use of a micro fluidic reactor for producing starch particles and the use of starch perticles are provided.
