1. A machine for processing a liquid food substance, the machine comprising:
a container delimiting a food cavity configured for containing the liquid food substance;
an impeller configured for driving the liquid food substance in the food cavity;
a housing delimiting a powered cavity adjacent the container, the housing containing:
a motor configured for driving the impeller;
a thermal conditioner configured for generating heat in the food cavity and/or for removing heat from the food cavity; and
a heat evacuation system configured to evacuate heat from the powered cavity to a space outside the machine, the heat evacuation system comprising a motorized ventilation arrangement and at least one flow path extending in the powered cavity from at least one air inlet opening in the housing to at least one air outlet opening in the housing via the thermal conditioner;
a control unit configured to control the motor and the motorized ventilation arrangement,
the motorized ventilation arrangement comprising a first ventilation device driven by the motor,
further to the first ventilation device and to the motor, the motorized ventilation arrangement comprises a second ventilation device and a further motor that is different than the motor, the further motor being controlled by the control unit to drive the second ventilation device, the first ventilation device and the second ventilation device configured to drive air along the at least one flow path;
wherein the heat evacuation system is configured to evacuate heat generated in the powered cavity predominantly via the at least one air outlet opening.
