Abstract

L'invention concerne un dispositif d'impression 3D par extrusion pour chocolat, lequel comprend une pompe à engrenage pourvue intérieurement d'un engrenage, un moteur électrique relié à la pompe à engrenage, un réservoir d'alimentation relié à la pompe à engrenage et en communication avec celle-ci, et une buse, la pompe à engrenage étant pourvue d'un orifice d'alimentation et d'un orifice de décharge, le réservoir d'alimentation étant monté au niveau de l'orifice d'alimentation, et la buse étant montée au niveau de l'orifice de décharge ; et le moteur électrique entraînant l'engrenage en rotation. Le moteur électrique entraîne la pompe à engrenage en fonctionnement afin d'aspirer le chocolat fondu contenu dans le réservoir d'alimentation vers la pompe à engrenage à partir de l'orifice d'alimentation, et celui-ci est ensuite extrudé hors de la buse le long de l'orifice de décharge. Une pompe à engrenage est utilisée comme source d'alimentation pour entraîner la décharge d'une matière première, remplaçant ainsi le procédé de décharge de produits similaires sur le marché impliquant un vérinage de tige filetée et une extrusion, et par conséquent, il n'est pas nécessaire de démonter et de monter un nouveau tube de matière, et la matière peut être fournie en continu.
