Abstract

Un mixeur (1a) comprenant un récipient (20), une pompe (28), une partie de coupe (41), une partie d'entraînement (26) et une unité de commande (29). Le contenant reçoit un matériau à pulvériser. La pompe évacue l'air de l'intérieur du récipient. La partie de coupe pulvérise le matériau à pulvériser. La partie d'entraînement amène la partie de coupe à tourner. L'unité de commande commande la pompe et la partie d'entraînement, et exécute une étape de dépressurisation et une étape de pulvérisation. Au cours de l'étape de dépressurisation, l'unité de commande commande la pompe et réduit la pression atmosphérique à l'intérieur du récipient pour atteindre 0,05 atm ou moins. Dans l'étape de pulvérisation, l'unité de commande commande la partie d'entraînement, amène la partie de coupe à tourner à une première vitesse de rotation dans une première période prescrite, et amène la partie de coupe à tourner à une seconde vitesse de rotation qui est supérieure à la première vitesse de rotation dans une seconde période prescrite qui suit la première période prescrite. Selon le présent mode de réalisation, il est possible de pulvériser la totalité d'un matériau à pulvériser qui comprend un solide et un liquide à l'intérieur d'un récipient à 0,05 atm ou moins.
