A homogenizer device for the production of whipped cream comprises an external sleeve (10) and an internal sleeve (11) between which is formed a labyrinth (13) in which the air-emulsified whipped cream is fed under pressure through an upstream conduit (25) and then delivered in a homogenized condition in a downstream position through a dispensing spout (22). The internal sleeve (11) features an axial bore (16) within which slides a stem (14) which is provided at its upstream extremity with an actuating piston (15) which also controls an aperture (24) providing communication between the delivery conduit (25) and the labyrinth (13). At its downstream extremity, the stem (14) acts on a separate valve (18) which is under tension from a spring (19) and which controls the outlet of the axial bore (16) communicating between the labyrinth (13) and the dispensing spout (22).
