Abstract

L'invention vise à fournir une buse d'air qui sèche un produit par élimination par soufflage du liquide de nettoyage résiduel se trouvant sur le produit, à l'aide d'un jet d'air. La configuration de la buse d'air comprend : un corps de fixation (A1) ayant une enveloppe cylindrique (2) et une base fixe (1) qui est reliée à l'autre extrémité de ladite enveloppe cylindrique (2) ; et un corps rotatif (A2) ayant une base rotative (3) qui est logé en rotation et installé à l'intérieur de la base fixe (1) et qui a une pièce de surface avant (31) qui est perpendiculaire à une ligne de l'axe de rotation (L) et qui est en regard d'une ouverture à partir de la face interne de l'enveloppe (2), et ayant un tube unique (41) d'éjection du jet et un tube de commande unique (42) qui sont disposés respectivement sur une pièce de surface avant (31b) et qui sont reliés par l'intermédiaire d'un passage d'air (31s). Le tube d'éjection d'un jet (41) est configuré de façon à pouvoir être fixé et mis en oscillation, par rapport à une ligne tangente d'un cercle de déplacement d'une pièce terminale de base du tube d'éjection du jet, à l'intérieur d'une plage angulaire prescrite sur les deux côtés de la ligne tangente sur un plan rotatif. Le tube de commande (42) est configuré de façon à pouvoir être fixé et mis en oscillation, par rapport à une ligne normale du cercle de déplacement de la pièce terminale de base du tube de commande, à l'intérieur d'une plage angulaire prescrite dans une région allant de la ligne normale au côté opposé au sens de rotation du plan rotatif. Le tube de commande (42) est agencé de façon à avoir un diamètre intérieur supérieur ou égal à celui du tube (41) d'éjection du jet.
