Beschreibung
Zusammenfassung:	This invention relates to a process for the continuous production of vegetal protein concentrates by removing the soluble carbohydrates by an aqueous alcohol from a defatted vegetable material said process requiring no frequent production interruptions for cleaning operations. The innovative process includes the steps of removing at least a fraction of the soluble carbohydrates by solvent extraction, the solvent being aqueous alcohol, to obtain a solvent wet protein rich vegetable material and a miscella; removing the aqueous alcohol form the solvent wet protein rich vegetable material to obtain a vegetable protein concentrate; wherein the solvent extraction takes place in a moving screen solvent extractor equipped with a cleaning means of the moving screen on its return journey and for which no plugging takes place for extended period of time.
