Abstract

L’invention concerne un procédé d’élaboration d’un produit pulvérisé permettant, même en cas de pulvérisation de matières possédant une pellicule mince et souple, telles que des grains de céréales, de rompre efficacement la pellicule mince et souple pour pulvériser les matières grâce à un appareil et un processus simples et former ainsi un produit pulvérisé contenant de fines particules de taille uniforme. L’invention concerne également un appareil et un produit pulvérisé. Selon l’invention, une paire de planches de pulvérisation (2, 3) dont la partie centrale comporte des faces de mouture (2a, 3a) et dont la partie périphérique comporte des faces de pulvérisation (2b, 3b) sont disposées en regard l’une de l’autre pour former une partie de mouture (5) et une partie de pulvérisation (6) entre les faces opposées. Au moins une (2) des planches de pulvérisation est entraînée en rotation par un module d’entraînement (M), une matière (10) à pulvériser est introduite dans la partie de mouture à partir d’une partie d’alimentation en matière brute (4). La surface des grains de matière introduite est moulue dans la partie de mouture (5) et les grains sont soumis à un concassage grossier. Le produit grossièrement concassé est pulvérisé dans la partie de pulvérisation (6) et un produit pulvérisé (20) est évacué d’une partie d’évacuation (18) située dans la partie de pulvérisation.
