A capsule processing machine (1) for preparing a beverage from a capsule (5) having a body (50) containing an ingredient. The machine (1) has a holder (10) with a cavity (11) having an upwardly oriented mouth (12) and a cover (20) cooperating with the holder (10). The cover (20) and the holder (10) are relatively movable along a movement path (14) from: an open position for inserting the capsule (5) inbetween the holder (10) and cover (20) into the cavity (11) and/or for removing the capsule (5) therefrom; to a closed position for extracting the capsule (5) in the cavity (11). The machine (1) includes a capsule transfer device (30) having a capsule guide (31) for guiding the capsule (5) from the holder (10) to a used-capsule evacuation area (40). The capsule guide (31) extends along an evacuation direction (31′) and is configured to seize the capsule (5) and hold the capsule (5) above the holder (10) and to guide the capsule (5) towards the evacuation area (40) along the evacuation direction (31′). The movement path (14) and the evacuation direction (31′) are at an angle (α1,α2,α3,α4) favouring a movement of the capsule (5) under the effect of gravity along the capsule guide (31) towards the evacuation area (40). The capsule guide (31) is tillable during the relative movement of the holder (10) and the cover (20) from the closed position to the open position to reduce the angle (α1,α2,α3,α4) so as to increase the effect of gravity for moving the capsule (5).

A beverage preparation machine (1) has: a water circuit (12,13) for guiding water (2,2′,2″) from a source (11); and a mixing unit (20) fluidically connected to the water circuit (12,13) and to a beverage outlet (23) for dispensing to a consumer cup or mug (5) a beverage (3) formed in the mixing unit (20). The mixing unit (20) has a first module (21) and a second module (22) that are relatively movable from: a distant configuration for inserting an ingredient between the first and second modules (21,22); to a proximate position for combining such ingredient with water (2′) supplied by the water circuit (12,13) so as to form the beverage (3). The machine has: a further unit (30) fluidically connected to the water circuit (12,13) and to an outlet (33) for dispensing to a consumer cup or mug water (2″) supplied by the water circuit (12,13); and a water directing device (14) fluidically connected to the water circuit (12,13), to the mixing unit (20) and to the further unit (30). The directing device (14) has one or more valves (141,142;143,144) that is/are actuated by the relatively moving first and/or second modules (21,22) and that can be opened and closed for controlling a flow of water (2,2′,2″) from the water circuit (12,13) selectively to the mixing unit (20) or to the further unit (30).
