Abstract (en)

The method of extracting natural hard wheat germ from a mass of grains containing a heterogeneous mixture of grains, germs and impurities comprises a first cleaning stage to eliminate a significant part of its waste and impurities having a similar size to that of the germs. From the cleaned mass a first mechanical separation stage consisting of passing the cleaned hard wheat over and through a grille is carried out to obtain a proportion of fine products containing germs mixed with grains and residual dust or waste. A second separation stage comprises a densimetric separation and is followed by a third stage of passing the fraction over a sieve to recover the graded fraction containing the germ. A final purification stage consists of passing the fraction over a purifier. An Independent claim is included for an extraction installation.

Abstract (fr)

L'invention concerne un procédé d'extraction dans son état naturel du germe de blé dur dans lequel, à partir d'une masse de céréales récoltées contenant un mélange hétérogène de grains, de germes et de déchets ou impuretés, on assure successivement et progressivement la séparation du germe pour le récupérer, ledit procédé étant réalisé par une suite d'étapes d'extraction exclusivement mécaniques et par voie sèche, sans apport extérieur de liquide. <IMAGE>
