Abstract: Systems, methods, and devices for evenly disbursing granular products. A device includes a hopper comprising a hopper sidewall and a hopper exit hole, wherein the hopper exit hole is formed in the hopper sidewall. The device includes a flowrate adjustor plate, wherein a position of the flowrate adjustor plate relative to the hopper exit hole determines a flowrate of a product that exits the hopper. The device includes an exit tube comprising a tube sidewall and an exit hole disposed at a distal end of the exit tube, wherein the product passes through an exit interior space defined by the tube sidewall. The device includes a blower in airflow communication with the exit tube, wherein activation of the blower causes the product to be pushed through the exit tube and dispersed through the exit hole in the distal end of the exit tube.
