A bag filling machine comprising a supply hopper, a material flow control mechanism and a rotatable bag filling spout is herein disclosed. The rotating bag filling spout is constructed and arranged for rotation about a vertical axis and is connected to the supply hopper through the material flow control mechanism so as to convey bulk commodities stored in the supply hopper into a bag that is to be filled. After the bag has been filled, the rotatable bag filling spout rotates to close the bag. A sealing mechanism is also provided to seal the filled bags once they have been closed by the rotating bag filling spout.
