Abstract
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 ().
