Abstract: A bagging apparatus, particularly for granular and/or powdery products, of the type adapted to vacuum-package granular and/or powdery products in bags, comprising at least one compaction chamber for the bag, in which at least one of the walls is movable and is adapted to apply a pressure to a surface of the bag, so as to expel therefrom the contained air and/or gases and compact the product, and at least one bell, which is provided with at least one filter probe, which is connected to air and/or gas suction elements and is adapted to produce vacuum inside the bag, the bell being associated with elements for bidirectional translational motion from an inactive retracted position to a suction position, in which the bell is at least partially inserted in a mouth of the bag so as to adhere perimetrically to an internal surface of the bag, elements being further provided for heat-sealing the mouth in the portion arranged in contact with the bell, the sealing elements being adapted to provide a final closure of the
