ABSTRACT:
Apparatus for washing hydraulic circuits involved in the preparation of milk-based beverages in machines for automatically dispensing hot drinks and/or in machines for preparing and supplying espresso coffee, said circuits comprising at least one first hydraulic path which extends between a point for detachable connection to a milk storage vessel and the orifice of at least one pouring spout of a delivery device. A motor-driven pump is arranged along said first hydraulic path and valve means allow washing liquid, drawn from a source to reach said first hydraulic path. The apparatus envisages a hollow, detergent-containing, cartridge provided with unions which, when it is required to perform washing, allow connection of the orifice of said at least one pouring spout supplied by said first hydraulic path to the said connection point which can be detached from the milk source.
