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.

In a device for feeding bulk dry material from a bag containing same, the device including means for supporting the bag above a spout or the like, the bag having a pourspout or the like generally centrally located in the bottom thereof through which the dry material is desirably discharged at a controlled rate into the spout, the improvement comprising means for deflecting the bag with respect to the bag support means to thereby agitate the dry material within the bag to improve its flow characteristics, said deflecting means being a substantially U-shaped, pivotally mounted bracket member mounted beneath the bottom of the bag that surrounds less than the entire circumference of the pourspout to thereby provide unimpeded access to the pourspout and spout, and means for selectively pivotally deflecting said bracket member upwardly against the bag bottom.
