Method of converting raw amylaceous, raw transformed thus obtained and their uses, in particular in the manufacture of paper, or products which adhesives

摘要

The invention relates to a novel method of transformation of starchy materials comprising a step of chemical in the dry phase fluidification, which step is carried out continuously and in particular operating conditions. These conditions allow in particular a residence time of the starchy material within the reactor of fluidification, which is greater than 5 minutes and less than 30 minutes.la starchy material subjected to the fluidizing may be a native or modified chemically and physically and / or in particular be cationised, hydroxyalkylated or acetylated. The starchy material may also be subjected, after melting, to a subsequent step of modifying the physical and / or chemical, in particular a step of cationisation or hydroxyalkylation.les processed products obtained according to the invention can be used advantageously for surfacing and the coating of paper, the size and finishing textile, the preparation of adhesives for plaster boards and corrugated cardboard, the preparation of gums and products gelled to use in food, pharmaceutical and cosmetics.
