The machine (10) comprises a pod-carrying body (16) having a seat (24) for receiving the pod (12) and a supply head (18). The pod-carrying body (16) and the supply head (18) are movable relative to one another between a loading position, in which the pod-carrying body (16) and the supply head (18) are spaced from one another to allow the pod (12) to be loaded in the pod-carrying body (16), and a position of compaction, in which the pod- carrying body (16) and the supply head (18) seal an extraction chamber where the pod (12) is compacted to a given final volume. The supply head (18) includes a plunger (38) arranged to slide within the seat (24) along a direction of compaction so as to compact by drawing the pod (12) received in the seat (24). The machine further comprises first adjusting means (52, 60) for discretely adjusting the final volume of the extraction chamber between a minimum value and a maximum value, and second adjusting means (66) for continuously adjusting the minimum value of the final volume of the extraction chamber. |
