Beverage machine with a non-homogeneous ingredient extraction configuration

Abstract

A machine () for preparing a beverage () from an ingredient () has an extraction unit () with: an ingredient extraction seat (); an inlet arrangement () for guiding water into the seat (); and a dispensing arrangement () for guiding beverage () out of the seat (). The dispensing arrangement () has a face () delimiting a downstream part of the seat (). The face () is made of an upper portion () and a lower portion () that are delimited by a substantially horizontal physical or notional delimitation line () that is located between a top end and a bottom end of the face (). The upper portion () is nude of an upper outflow passage () and an upper impervious part delimiting the upper outflow passage. The upper portion () has an upper surface area ratio transverse to a direction () of downstream flow in the seat () of: a surface area of the upper outflow passage () over a surface area of the upper impervious part. The lower portion () is made of a lower outflow passage () and a lower impervious part delimiting the lower outflow passage. The lower portion () has a lower surface area ratio transverse to the downstream flow direction () of: a surface area of the lower outflow passage () over a surface area of the lower impervious part. The face () has an overall ratio of the upper surface area ratio over the lower surface area ratio that is greater or smaller than 1.
