ABSTRACT:
A method and apparatus for assisting discharge flow in bins for flowable materials includes an elongated tubular, bag-shaped, inflatable membrane suspended from near the top of the bin and extending to just above a discharge opening in the bin. The membrane is inflated prior to filling the bin with material which has a tendency to cake or agglomerate. The material will set up around the inflated bag, and when the bag is deflated the material will flow out the opening of the bin, with an assist, if necessary, from a bin liner or the like.
