Abstract: The present invention refers to systems of distribution and preparation of edible products, that include cartridges (1, 1?) adapted for collection of single portions (2) of edible substances devoid of single packages, and apparatus (10) for preparation of edible products, such as aromatic beverages, for example espresso type coffee, adapted for operating single portions (2) in product preparation devices (12), for example extraction devices, whereby these systems present retention means (7) and, optionally, a respective connection disposition (8), adapted so that provide a simpler and more reliable regulation of delivery of single portions (2) one-by-one to said product preparation device (12), as well as present a simpler construction and provider enhanced ergonomics. The present invention further refers to processes of operation of systems of the type of the present invention.

Abstract: Systems and processes for preparing beverages, in particular espresso coffee and similar aromatic beverages, having at least one type of drinking recipient, for example of glass type, cup or similar, and an apparatus having a beverage discharge disposition operatively associated with a beverage preparation device adapted so that can be driven by a motorized actuation device and collect an individual portion of beverage ingredients. The apparatus has a control mechanism configured so that can process data of several operative parameters of the apparatus, including data relating to the entry of the individual portion in the beverage preparation device and data relating to the position of the actuation device, and being further configured so that can automatically determine the start and end of fluid injection and beverage discharge in a more ergonomic manner.
