Zusammenfassung:A process for producing starch pastes, in particular for manufacturing corrugated paper or cardboard, of the type comprising the stage of preparing a primary paste cold from a gelatinized starch in the presence of an alkaline agent, is characterised by the fact that the primary paste is made from a first portion of an aqueous starch suspension which is subjected to the action of an alkaline agent in excess, that the primary paste is mixed with a second portion of the said suspension, and that at least part of the alkaline agent present in excess is neutralised with boric acid. A plant for operating the process is also described.
