Machine for homogenising a food substance

Abstract

A machine () for homogenising a food substance has: a container () with a side wall () and a bottom wall () delimiting a cavity ('); an impeller () with an impelling member () forming an impelling surface (′) that is drivable in rotation (r) about a central axial direction (′) of the impelling surface (′″) for imparting a mechanical effect to the food substance; and a module () which has a housing means (′) that contains an inner chamber () and that delimits a seat () for the container (), the chamber () containing an electric motor (). The electric motor () has an output drive axis (′) with a driver device (″) configured to drive a follower device () of the impeller (). The driver device (″) and the follower device () are magnetically coupled through a sidewall () and/or bottom wall () of the container (). The driver device (″) comprises a ferromagnetic or magnetic field-generating element () that is arranged to be magnetically coupled to a corresponding ferromagnetic or magnetic field-generating element () of the follower device (). The follower device () extends over a predominant part of the bottom wall () of the container () or across a substantial part of the wall () along a diameter thereof. The driver device () extends over a predominant part of a bottom part of the seat () or across a substantial part of the bottom part of the seat () along a diameter thereof. The ferromagnetic and magnetic field generating elements () are positioned at extremal or peripheral parts of the follower device () and of the driver device (″).
