Abstract: A dispenser product supply unit includes a pressurizable container for containing a product liquid and having an opening leading into one end of a conduit. Formed integrally in the conduit is a mixing chamber at which a gas may be added to the liquid followed by an elongated turbulence tube for causing turbulent flow of the mixed fluids. The opposite end of the conduit may be coupled to a distribution manifold that can distribute the aerated liquid issuing from the turbulence tube onto a surface as a relatively thin layer. Side branches from the conduit may also be present for introducing one or more additives into the fluid flowing through the conduit. The container conduit and side branches constitute an integral disposable structure. The unit is especially suitable for producing and distributing flavored ice cream and yogurt from associated dispensing apparatus.
