For this project, the Customer required specially designed, food-grade screw feeders located under hoppers to meter dry cereal. The hoppers served to store out-of-spec cereal generated during startup or upset conditions. The out-of-spec product was typically of irregular size or color. The screw feeders metered the product into a tubular drag conveyor that conveyed the product downstream for further processing. Since the cereal was meant for human consumption, KWS took care to specify, design, and manufacture the screw feeders to meet the sanitary requirements of the Customer.
