摘要： A milk frother/heater for a milk supply circuit in a beverage vending machine has a plastic hollow body made of one or more undismountably coupled parts and integrally has a first appendage defining a milk inlet to receive either smooth milk or a milk-air mixture, a second appendage defining a steam inlet to receive steam, and a third appendage defining a milk outlet to deliver cold or hot, smooth or frothed milk. The body internally defines a mixing chamber, and the milk inlet, the steam inlet and the milk outlet internally define a milk inlet passage, a steam inlet passage, and a milk outlet passage, respectively, in fluidic communication with the mixing chamber. The mixing chamber has an axis and includes a first closed axial end and a second axial end, opposite the first axial end, at which the steam inlet passage and the milk outlet passage end up. The milk inlet passage either ends up directly in the second axial end in the mixing chamber or merges with the steam inlet passage upstream from the mixing chamber.
