The system includes a machine for breaking dried leaves. The machine comprises an inlet for supplying the dried leaves, an outlet for releasing the broken leaves, and breaker devices including a first breaker member (6) and a second breaker member (8) removed relative to the first breaker member. The first and second breaker members bend the dried leaves until the leaves break. The machine further includes a neutral gas source configured to feed the environment in the machine in order to avoid an oxidation of the leaves at the time of braking until its insertion in a sealed capsule.

The machine further includes a neutral gas source configured to feed the environment in the machine in order to avoid an oxidation of the leaves at the time of braking until its insertion in a sealed capsule. The three breakers devices of different size are configured for breaking the dried leaves. The breaker devices are mounted one on the other in a direction of a force of gravity. The first breaker device is removable and includes rotatable rollers (16a-16c). The rollers include active lines with an upper surface interrupted by cavities, and are configured to take delivery of the leaves. The active lines are separated by grooves surrounding the rollers. The cavities have radial surfaces formed with the upper surface, and side surfaces formed with the radial surfaces. Depths of the cavities compared to the upper surface and/or widths of the cavities and widths of the grooves are different from one breaker device to the other breaker devices. The widths of the cavities and the grooves of the removable break
