Abstract

L'invention a pour but de proposer un dispositif d'agitation/de démoussage apte à diminuer une montée en température dans une matière pendant l'agitation et le démoussage, à réaliser une agitation et un démoussage de façon fiable et à empêcher un changement des propriétés de la matière. La solution consiste à proposer un dispositif d'agitation/de démoussage (1) comprenant des moyens de rotation et des moyens pour faire tourner un récipient (2). Dans ce dispositif d'agitation/de démoussage, la matière à l'intérieur du récipient (2) est au moins agitée ou démoussée par la rotation du récipient (2). Le dispositif comprend de plus : plusieurs supports de récipient (11) chacun maintenant un récipient (2) ; des moyens de rotation (12) disposés de façon à porter en rotation chaque support de récipient (11) et de façon à tourner autour d'un axe de rotation (12a), les moyens de rotation faisant tourner chaque support de récipient (11) autour de l'axe de rotation (12a) ; des moyens d'entraînement (3) pour entraîner en rotation les moyens de rotation (12) ; un générateur d'air froid (7) pour générer de l'air froid ; et une buse (8) communiquant avec le générateur d'air froid (7) pour décharger l'air froid vers la partie périphérique externe des récipients (2).
