A pivotally mounted U-shaped bracket assembly is disposed beneath the bottom of a bag containing a quantity of bulk dry material and surrounding a pourspout in the bottom of the bag. An air cylinder comprising an inflatable bladder positioned opposite the pivotal mount of the bracket selectively pushes the bracket upwardly into the bottom of the bag to dislodge the dry material and separate it into its original granulated or powdered form and break up any agglomerations or solidifications thereof which would otherwise interfere with the free flow of dry material from within the bag and through the pourspout. A vibrator is vertically mounted on the outboard end of the bracket and introduces vibratory forces into the material as the bracket deflects the bag to further aid the free flow of material.
