Beschreibung
Zusammenfassung:	The invention relates to a motorized base (12) for a food preparation appliance of the type comprising, in an outer casing, an electric motor (30) which rotates a fan (40) that discharges an outgoing flow of air that is channeled along a downstream circuit (44) to an outlet opening (46). According to the invention, the downstream circuit (44) comprises, between a transfer conduit (50) and the outlet opening (46), a double vent (56) having an upstream tubular outer channel (58) which extends in a venting direction (A2) from an upstream end connected to the transfer duct (50) and which is fluidically connected, via a turnaround volume (60), to a downstream inner channel (62) extending inside the volume of the upstream tubular outer channel (58) in the venting direction (A2) as far as a downstream end that corresponds to the outlet opening (46).
