extraction du fourrage grossier

OBS: Ne pas confondre avec le blutage qui consiste à tamiser la mouture (généralement la farine) pour en extraire les particules non désirées comme le son et l'albumen non réduit.

CONT: Scalping: In this process, an airscreen cleaner is used immediately after harvest to remove large volumes of green material, which may cause heating. A scalper can also remove largevolumes of sticks, stems, hulls and other inert material. Scalping makes other cleaning operations more efficient.
OBS: Not to be confused with bolting which consists of sifting mill stocks (usually flour) to remove unwanted particles like bran and unreduced endosperm.
