CF raw meal silo
Layers of raw meal of varying chemical composition are fed to the silo. The variations in extraction rate/residence time mean that these layers are broken up as they proceed down through the silo. The resulting raw meal product, extracted from the silo during any stage of the extraction sequence, will there-fore be a mixture of raw meal compo-
