A machine () for processing a liquid food substance incorporates: a container () delimiting a cavity (') for containing said liquid food substance; an impeller () for driving the liquid food substance in the container (); a motor () for driving the impeller (); a motor chamber () for containing the motor (); and a means for evacuating heat from the motor chamber (). Such means comprises one or more movable members () that are driven by the motor () and that are configured to circulate air () in the motor chamber () to evacuate heat therefrom.

Heat management for food processor

The method prevents or inhibits, during a heating process, burning in a food heating device () of a flowable food substance against a heating surface () delimiting or contained in a device's cavity () that contains the food substance. The heating device comprises an agitator () movable in the cavity (). The method includes the steps of: introducing the flowable food substance into the cavity (); heating the heating surface () and moving the agitator () at an agitator speed () to generate in the cavity () a flow of the food substance over the heating surface () and in contact therewith; and disturbing the flow of the food substance to break and/or causing asymmetric flow of the food substance in the cavity (). At a first agitator speed () during the heating process, the food substance is caused to flow at different first relative local speeds over the heating surface () that includes a first minimum speed location () over which the food substance flows at a first minimum speed of the different first relative local speeds. The speed of the agitator () is changed during the heating process to a second speed (), the food substance being caused to flow at different second relative local speeds over the heating surface () that includes a second minimum speed location () over which the food flows at a second minimum speed of the different second relative local speeds. The second minimum speed location () is different to the first minimum speed location ().
