Abstract (en)
[origin: EP4108578A1] The invention relates to a device (1) for extracting gas from the upper part of a bag (100) containing a powdered material, corresponding machine and method. The device (1) comprises cannulas (2) with gas driving means (4) at a distal end (6) and first clamps (10). The cannulas (2) are movable along a first direction (A) for being inserted into the opening (102) of a bag (100), and along a second direction (B), perpendicular to said first direction (A), for holding the opening of the bag (100) in a spaced position. The clamps (10) can be moved between an open position and a closed position in which the opening (102) is pressed between the first clamps (10). When the cannulas (2) are in said spaced position and the first clamps (10) are in said closed position of the first clamps, the first clamps (10) are movable along said first direction (A), in the direction moving away from the opening of the bag for extracting gas from said bag (100) .
