Abstract
A machine for preparing aromatic beverages by extraction, such as espresso coffee and similar beverages. The machine comprises at least one optimized beverage discharge disposition, in particular presenting a first and second flow sections separated by a throttling section that configures a double deflection of the prevailing flow direction, so that it provides a streamlining of the discharge flow.
Claims15
A machine (1) adapted for the preparation of aromatic beverages comprising:
- a machine body (2),
- at least one extraction device (3) adapted for an extraction of a dose of a beverage ingredient,
- at least one beverage discharge (4) disposed downstream of said at least one extraction device (3), and
- a flow discharge disposition (5) providing a flow connection for a flow of a liquid between said at least one extraction device (3) and said at least one beverage discharge (4),
- whereby said flow discharge disposition (5) comprises first and second flow sections (51, 52) arranged horizontally along a horizontal flow direction and separated horizontally by a throttling section (53),
- wherein each of said first flow section, said second flow section and said throttling section has a horizontally oriented flow passage area,
- wherein said first flow section comprises an inclined plane that is ascending in a downstream section thereof,
- wherein said throttling section has a vertically extending throttling wall (55) with a distal end that extends downwardly toward a common wall which comprises a top surface of the first flow section (51) and a top surface of the second flow section (52) and presents a smaller horizontally oriented flow passage area between the distal end of the throttling wall (55) and said common wall than an area of said first and second flow sections (51, 52),
- wherein each of said first and second flow sections (51, 52) comprises at least one exhaustion opening (54) disposed vertically above said horizontal flow direction and adapted so that said at least one exhaustion opening can provide for air to exit from said flow discharge disposition (5), and
- wherein said throttling section (53) provides in succession a first deflection of the flow of liquid in a downward direction before the distal end of the throttling wall (55) and a second deflection of the flow of liquid in a lateral direction upon encountering the common wall at the distal end of the throttling wall (55).

- a flow discharge disposition (5) providing a flow connection for a liquid flow between said at least one extraction device (3) and said at least one beverage discharge (4),
- whereby said flow discharge disposition (5) has an enclosed top and comprises first and second flow sections (51, 52) arranged along a lateral flow direction from upstream to downstream and separated by a throttling section (53), having a throttling wall (55) extending downward from said top to a distal end, separating said first and second flow sections (51, 52), said distal end comprising a smaller flow passage area than said first and second flow sections (51, 52), and said first and second flow sections (51, 52) comprise at least one exhaustion opening (54) in said enclosed top that is adapted so that said at least one exhaustion opening can provide for air to exit from said flow discharge disposition (5),
- wherein said throttling section (53) configures a first deflection of the flow of liquid in a downward direction and a second deflection of the flow of liquid in a lateral direction, and
- wherein an interior surface of said first flow section (51) comprises a horizontal part in an upstream region and an ascending inclined part in a downstream region of said first flow section (51).
