Abstract

Machine de moussage de lait (100), comprenant un boîtier (10), un cylindre de lait, un dispositif de mesure de distance (11), un orifice d'alimentation en vapeur (12), un ensemble entraînement (20) et un tube d'insertion de vapeur (13). Le cylindre de lait destiné à contenir du lait est disposé de manière amovible sur le boîtier (10), le dispositif de mesure de distance (11) est conçu pour mesurer la hauteur d'une surface de liquide dans le cylindre de lait, l'orifice d'alimentation en vapeur (12) est conçu pour fournir de la vapeur et le tube d'insertion de vapeur (13) est en communication fluidique avec l'orifice d'alimentation en vapeur (12) et est conçu pour libérer de la vapeur. Le tube d'insertion de vapeur (13) est relié à l'ensemble entraînement (20) et est mobile verticalement sous l'entraînement de l'ensemble entraînement (20) entre une première position et une seconde position par rapport au boîtier (10). Lorsque le tube d'insertion de vapeur (13) est situé au niveau de la première position par rapport au boîtier (10), une extrémité du tube d'insertion de vapeur (13) est située au-dessous de la surface liquide du lait. De la vapeur peut ensuite être transportée à travers l'extrémité du tube d'insertion de vapeur (13), de façon à fouetter le lait. Lorsque le tube d'insertion de vapeur (13) est situé dans la seconde position par rapport au boîtier (10), le tube d'insertion de vapeur (13) quitte complètement la surface liquide du lait. Au moyen de la machine de moussage de lait (100), le lait dans le cylindre de lait peut être automatiquement fouetté, de telle sorte que l'efficacité de fouettage est plus élevée.
