Feed Rite Automation Inc. offers a variety of bulk storage hoppers. These range in size from 0.5 to 6 cubic feet in capacity and are an excellent addition to any bowl feeder. These hoppers are equipped with either a mechanical Paddle Switch, or an Electronic Sensor. These devices turn the hopper ON or OFF to maintain the optimum amount of product in the bowl. Not only does this make the bowl more efficient, it also allows it to run longer without a product load operator.
