1. A device for filling a recipient with at least one material in a form of a powder, the device comprising: a filling channel configured to bring the material from a reserve of material to an entry opening of the recipient; andmeans for evacuating a pneumatic fluid contained in the recipient, the means for evacuating including at least one first evacuation duct configured to connect an inside of the recipient to an environment outside of the recipient during a filling phase, the first evacuation duct being internal to the filling channel, and the means for evacuating further including a second evacuation duct configured to evacuate the pneumatic fluid before filling, the first evacuation duct including an end configured to face the opening of the recipient and the second evacuation duct including an end configured to face the opening of the recipient, the end of the first evacuation duct being distinct from the end of the second evacuation duct. 2. A filling device according to claim 1, wherein the second evacuation duct is connected to the first evacuation duct. 3. A filling device according to claim 1, further comprising an aspirator of air contained in the recipient and connected to the first and/or to the second evacuation ducts. 4. A filling device according to claim 2, further comprising an aspirator of air contained in the recipient and connected to the first and/or to the second evacuation ducts. 5. A filling device according to the claim 3, wherein the aspirator includes a pneumatic pump. 6. A filling device according to claim 4, wherein the aspirator includes a pneumatic pump. 7. A filling device according to claim 5, wherein the first evacuation duct is connected to the pneumatic pump by at least two or three secondary ducts, distributed angularly in a regular manner around the first evacuation duct. 8. A filling device according to claim 6, wherein the first evacuation duct is connected to the pneumatic pump by at least two or three secondary ducts, distributed angularly in a regular manner around the first evacuation duct. 9.
