Peanut waste can be sluggish, with a high tendency to pack and difficult to convey. KWS designed an inclined conveyor with ease of maintenance while maintaining food grade quality surface finish. Breaker bars were located on the screw at inlet and discharge points to break up large chunks of peanut waste.

KWS provided a screw feeder to meter green coffee beans from a storage bin to the roasting process. The screw feeder was designed with a long open inlet to properly empty the entire length of the storage bin. Variable pitch flighting was used to evenly meter the coffee beans for a first-in, first-out sequence which is vital to keeping the coffee beans fresh.

NBE designed a custom box filling station for various cereals at 20 totes per hour. The Gaylord Fill Station was located in an area with a very low ceiling height. NBE designed around existing equipment with a fixed infeed tube. Light curtains and safety caging were integrated to eliminate operators from entering the processing area. The project included a Risk Assessment and Category 3 safety circuit control package.

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.

Today’s pet food manufacturers are constantly searching for methods to improve process efficiency, changeover times, and, of course, ensuring product safety. One of the key technologies which can help address and improve all of these factors is the method of pneumatic conveying used in each process step, whether it is for the raw ingredients (major and minors), for the pet food kibble or ingredient blends prior to their next process step or for the final product prior to packaging. Older methods of transferring finished products and even raw ingredients via mechanical means such as drag conveyors or spiral screw conveyors are quickly diminishing. Pneumatic conveying is often chosen as a clean and versatile method for pet food manufacturers to efficiently transfer finished products and raw ingredients from point A to point B in a completely contained manner. Pneumatic conveying offers a much cleaner and safe alternative. By properly selecting the best pneumatic conveying method for the application, a much more cost effective and reliable means of material handling can be achieved. This white paper will outline and define the methods of pneumatic conveying available, with an emphasis on the advantages of dense phase conveying types for a variety of unit operations in pet food processing.

A customer purchased a mobile, circular vibratory, bag dump screener from Kason Corp. that discharges into the feed hopper of a flexible screw conveyor. The screener is a VIBROSCREEN Low-Profile FLO-THRU model with a single-deck 30 in. (762 mm) diameter screen and built-in dust collector. A worker now dumps a full bag of dry ingredients onto the screen that reduces physical effort, while the dust-containment system improves safety and plant hygiene. The screener employs two imbalanced-weight gyratory motors, mounted externally on opposite sides of the screener, to impart multi-plane inertial vibration that maximizes the rate at which particles pass through or across the screen surface. Material clumps and foreign material discharge through an “overs” discharge spout at the screen’s periphery, while on-size particles (≤5.66 mm) gravity discharge at a rate of 50 lb/min (23 kg/min) into a flexible screw conveyor that is 6 in. (152.4 mm) in diameter, 6 ft (1.8 m) long and inclined at 45-degrees. Screened material is conveyed into mobile bins that are wheeled to the “processing” side of the plant for blending with proteins and cooking.
