Abstract

L'invention concerne un procédé de broyage de blé par coupe et mouture par extrusion à basse température et à haut rendement comprenant une procédure de mouture de balle, une procédure de mouture de résidu, une procédure de mouture de grain, une procédure de mouture de queue et une procédure de nettoyage. La procédure de mouture de balle présente quatre étapes de mouture de balle, la procédure de mouture de résidu présente deux étapes de mouture de résidu et la procédure de mouture de grain présente quatre étapes de mouture de grain. Une machine de coupe et de mouture par extrusion à grande vitesse est utilisée pour la troisième étape de mouture de balle, un jeu minimal de broche de rotor et de broche de stator de la machine de coupe et de mouture par extrusion à grande vitesse étant de 0,3 à 1 mm, une vitesse linéaire de la broche de rotor la plus à l'extérieur étant de 30m/s à 70 m/s. La machine de coupe et de meulage par extrusion à grande vitesse pour la troisième étape de mouture de balle traite un son sec produit lors de la deuxième étape de mouture de balle. L'invention concerne également un appareil de mouture de blé qui utilise le procédé de broyage de blé par coupe et mouture par extrusion à basse température et à haut rendement. La présente invention revoit la conception du procédé de mouture en utilisant la machine de coupe et de mouture par extrusion à grande vitesse pour la troisième étape de mouture de balle, la quatrième étape de mouture de balle et la première étape de mouture de résidu, en utilisant une machine de coupe et de mouture par extrusion à grande vitesse refroidie à l'eau pour un système de mouture de grain et en réalisant une extraction de germes dans la seconde étape de mouture de résidu de sorte qu'un taux d'extraction de germes de chaîne de production est au moins doublé, la précision et l'extraction totale de farine sont augmentées, l'investissement de chaîne de production est significativement réduit et une odeur de blé d'origine est conservée.
