Abstract

L'invention concerne un dispositif de transformation d'aliments (10a; 10b; 10c), en particulier un dispositif de récipient de cuisson, comprenant au moins une unité d'agitation (12a; 12b; 12c) et au moins une unité d'entraînement (16a; 16b; 16c) disposée dans une zone supérieure (14a; 14b; 14c) de l'unité d'agitation (12a; 12b; 12c) pour entraîner l'unité d'agitation (12a; 12b; 12c). Afin de perfectionner avantageusement un dispositif générique, il est proposé que le dispositif de transformation d'aliments (10a; 10b; 10c) comprend une unité de couplage magnétique (18a; 18b; 18c) qui est conçue pour transmettre magnétiquement un couple d'entraînement de l'unité d'entraînement (16a; 16b; 16c) à l'unité d'agitation (12a; 12b; 12c) par le biais d'au moins un espace intermédiaire (20a; 20b; 20c)
