摘要

Method of making beverage from sealed capsule powder material. In a coffee machine (1), sealed capsule (2) is fed with a certain amount of cup axial space (42) aligned along horizontal axis (9) with pressurized hot water spray (13) and is moved toward to the sprayer (13) to press the annular flank (4) of the sealed capsule (2) hermetically against the sprayer (13) to pierce the front sealing wall (6) of the sealed capsule (2) by means of the first piercing device (21), to feed pressurized hot water through the sealing wall (6) to expand the sealed capsule (2) axially and eliminate the axial space and place the back wall (5) of the sealed capsule (2) in airtight contact with the second device. (44) and pierce the back wall against the second piercing device (44) so that coffee flows out through the second piercing device (44).
