The complete material handling system provided by Coperion K-Tron includes several pneumatic transfer lines for various stages of the peanut butter process. First, raw peanuts are vacuum conveyed direct to a peanut roaster. After the peanuts are roasted, a second line transfers them under vacuum to the blancher. Once the peanuts are blanched, they are then vacuum conveyed to yet another line. There, they are metered via a Coperion K-Tron weigh belt feeder to a screw conveyor, and both sugar and salt are added to the nuts via Coperion K-Tron loss-in-weight feeders.

Defining Feeder Accuracy For Continuous Processing
Processing Magazine
Continuous processing is a manufacturing practice that has been used in the plastics, chemical and food industries for decades. Although primarily used for liquid processing, the innovations made in dry powder feeder technologies have enabled the use of continuous dry ingredient feeding for a variety of applications.

Optimize Feeding to Make More Money in Twin-Screw Compounding
Plastics Technology
Every business want to increase profits. Companies can deploy many strategies to do so that can fall across various areas of the business, such as reducing inventory, negotiating lower prices from suppliers, or increasing marketing efforts, to name a few. When it comes to operations, the capital equipment is often already in place and is therefore a sunk cost. Increasing profitatbility in this case is usually depends on maximizing productivity of these assets. For twin-screw extrusion processes, this is most easily achieved by increasing throughput rate, thereby spreading operation costs over a greater amount of product produced in the same unit of time.

Three ways to improve continuous loss-in-weigh feeding accuracy
Powder Bulk Engineering
The weigh accuracy of individual recipe ingredients for a continuos blending, granulation, or extrusion process has a direct effect on product quality and bottom-line savings. This article explains how to optimize continuous loss-in-weight feeder accuracy by separating plant vibration noise from true weight loss, controlling motor speeds during feeder refill, and compensating for process pressure fluctuations.

Better Pelletization under Water
Kunststoffe International
Die Plate Wear Protection Doubles Service Life - A new development in wear prevention on underwater pelletizer die plates is opening up the way to significant reductions in production costs, in particular for the production of polyolefins. This new wear protection is now available for the first time for the die plate of an increased capacity underwater pelletizer for throughputs of up to 70 t/h.

Feeding in a Closed System
Kunststoffe International, 1-2/2016
In a gravimetric feeding system that is closed off and independent of environmental atmosphere, pressure variations inside the material feed hopper may lead to weighing errors. This has a negative impact on product quality as well as production costs. The newly developed electronic pressure compensation (EPC) system offers a reliable and cost-effective solution to solve this problem.

Compounding of Polycarbonate: Advantages of the Co-Rotating Fully Intermeshing Twin Screw Compounding Extruders Technology
Plastics Technology Magazine, 6/2015
The co-rotating, fully intermeshing twin-screw extruder is the primary production unit for compounding of polymer based materials. Coperion has delivered its first co-rotating, fully intermeshing twin-screw compounders type ZSK for compounding of Polycarbonate more than 30 years ago and has meanwhile the largest population of extruders for manufacturing polycarbonate as well as for compounding polycarbonate, e.g. alloys with ABS or filled with glass fibers, talc or pigments.

Black and Finely Dispersed - Compounding Carbon Black Masterbatches for Polyester Fibers
Kunststoffe International, 6-7/2015
A carbon black masterbatch used for coloring polyester fibers has to fulfill high standards, especially if the intended results are filmy spinning fibers for very soft and comfy textiles. Taking a Coperion twin-screw extruder as exemplary, it is shown how screw configuration and processing parameters affect the dispersability of carbon black and material degradation in the polyester matrix.

Food Processing Equipment Trends
Western Food Processor
Today’s food manufacturers are looking for ways to boost production runs, simplify cleanup and sanitation, control ingredient costs, reduce changeover times between runs and increase the ability to produce a variety of product types and sizes, all with an emphasis on cutting cost but improving overall food safety. Automation of the complete process is a key trend in food manufacture from raw ingredient receipt and transfer, including various pneumatic transfer options, batch weighing techniques, and continuous feeding methods, all the way to the extrusion, and packaging steps downstream.
