A coffee machine including a frother with an outlet channel for coffee and milk foam, and supply channels for milk, air, and steam respectively, and a nonreturn valve to prevent a fluid in one of the channels from flowing in an undesirable direction. The coffee machine also includes a clean water supply channel that connects to the milk supply channel with a T-junction distant from the frother. The T-junction further connects to a source channel for the milk.

A cleaning apparatus for a beverage preparation machine comprises at least one fluid processing device comprising a fluid processing body provided with an outflow portion for the outflow of a cleaning fluid. The fluid processing body comprises at least one of the following means: inlet means for introducing a fluid substance into a container for the preparation of a beverage product by mixing of the fluid substance with an ingredient contained in the container; outlet means for allowing the outflow of the beverage product from the container once the fluid substance is introduced into the container and is mixed with the ingredient. The cleaning apparatus further comprises a cleaning device comprising a cleaning body, which in turn comprises one or more movable elements defining a chamber for housing at least a portion of the fluid processing body, and movement means for moving the one or body are dimensioned and shaped such that, in the active position, the one or more movable elements enclose at least a portion of the fluid processing body in the chamber, such that the cleaning fluid can circulate in a space between the fluid processing body and the one or more movable elements when said cleaning fluid is ejected from the outflow portion of the fluid processing body. In the inactive position the one or more movable elements are moved away from the fluid processing body, such that the fluid processing body and the container can be functionally connected together for the preparation of the beverage product and/or the outflow of the beverage product.

The invention relates to a flow separation device (100), which may be provided in a beverage preparation device (1). The flow separation device (100) in particular effects an easier separation (redirection) of a flow. The flow separation device (100) comprises a first delivery line (30) to drain water from a buffer tank (2), a branching section (29) provided downstream the first delivery line (30), wherein the branching section (29) branches the first delivery line (30) into a second delivery line (28) and a third delivery line (23), each of the second and third delivery line (28, 23) leading to a respective discharge outlet (22; 24), and a flow rate control device (26) for delivering water through the flow separation device (100) and for adjusting the flow rate of the water. Each of the second delivery line (28) and third delivery line (23) comprises a respective section (281; 231), wherein said sections (281, 231) are arranged such that if water is delivered by the flow rate control device (26) at a flow rate below a defined threshold value the water is delivered beyond the section (281) of the second delivery line (28) but not beyond the section (231) of the third delivery line (23), thereby discharging the water via the discharge outlet (22) of the second delivery line (28), and if water is delivered by the flow rate control device (26) at a flow rate at or above the defined threshold value the water is at least partially delivered beyond the section (231) of the third delivery line (23), thereby discharging the water at least partially via the discharge outlet (24) of the third delivery line (23).
