ABSTRACT:
A method for cleaning bulk bags which have been utilized to transport dry bulk, the method including the steps of providing a first bulk bag to be cleaned; mounting the bulk bag on a frame through its inlet and outlet spouts; providing a vertically inclined brush substantially the same length as the mounted bulk bag; introducing air in the mounted bulk bag from the frame to inflate the bulk bag to its filled configuration; rotating the brush against the wall of the bag which in turn causes the bag to rotate on its axis, thus cleaning the exterior wall of the bag, and shaking material off of its interior wall; suctioning off material removed from the brush; collecting the material from the interior of the bag in a collection compartment; and mounting a second bag on the frame while the first bag is being cleaned; following the cleaning of the first bag, rotating the frame to place the second bag in alignment with the brush; inflating the second bag; and rotating the brush against the wall of the second bag to clean the exterior and interior wall of the bag; deflating the first bag and removing it from the frame, and while the second bag is being cleaned, mounting another bag on the frame for cleaning.
