At Powtech 2019, Coperion and Coperion K-Tron will present their versatile bulk materials handling solutions for various process steps at their booth no. 4-290 in Hall 4. Along with the newly redesigned stainless steel WYK diverter valve for CIP cleaning and the ZV rotary valve, now also available in larger sizes, visitors will be impressed by the variety of components and products for safe and economical bulk materials handling that Coperion and Coperion K-Tron offer.

New WYK Bulk Material Diverter Valve

For parts used in manufacturing processes in many sectors of the food, pharmaceutical and chemical industries, the highest requirements in hygiene and purity apply. Moreover, frequent product changes and difficult product characteristics require regular wet cleaning. If cleaning expenditures can be minimized, companies can save significantly on time and costs.

Coperion addressed these issues more than ten years ago, developing the WYK for powder and pellets, which was awarded the Innovations Award by the Powtech exhibition in 2006. The diverter valve enables CIP applications to fulfill required criteria especially in the food sector that come down to one thing: The diverter valve must be absolutely clean and free of contamination after wet cleaning — with no additional disassembly or manual cleaning. This saves time, effort and costs since manual post cleaning is not necessary. In doing so, the WYK diverter valve can easily be installed even at points that are poorly accessible.

Throughout its inception, Coperion has continued to develop the WYK diverter valve based upon the collective experience of past years. Its innovative basic function has not changed: During bulk material conveying, the conical rotor seals the conveying pipes to each other. During CIP cleaning, the rotor is minimally pulled out of the housing and flushed by the cleaning fluid. Now, the diverter valve has been optimized according to current EHEDG guidelines (Class I EL certification is currently in process). Coperion redesigned and optimized the CIP-capable pipe sealing such that now operation with even the finest powders is possible. The pneumatic drives are separated — for turning and pulling the rotor, respectively — so that the rotor is supported on both sides. Along with its compact design, the diverter valve offers an improved cast design with increased surface quality. All materials conform to (EC) Regulation no.1935/2004 and the sealing materials are FDA-conform as well. Moreover, further flange connections, such as those per DIN 11864, can be realized simply on the housing.

The diverter valve is available in sizes DN 65, 80, 100 and 125. It is also available as a standard stainless steel diverter valve without the CIP cleaning function for non-wet cleaning applications. The diverter valve will be offered in Europe and Asia beginning of September 2019 and is expected to be offered in the USA by year end.

New ZV rotary valve housing for pellets and coarse-grained products

Coperion’s redesigned and optimized ZV rotary valve is now also available in sizes from 400 to 630. In comparison to its predecessor models, it excels above all with a lower granulate destruction during operation. Coperion enlarged the inlet cross section with additional pellet deflecting profiles. In doing so, an increase in throughput performance of up to 20% results.

Even noise emissions from leakage gas expansion, which constitute the primary source of noise in high-pressure rotary valves (up to 3.5 bar differential pressure), have been markedly reduced with a new expansion opening design. Additionally, Coperion integrated the transition of the elongated opening to a pipe connection within the cast. Beyond reducing the noise emission, an adapter is likewise no longer required. Moreover, the ZV rotary valve now has a standard-compliant pipe connection.

The “Battery Show Europe” in Stuttgart: Asahi Kasei Introduces Innovative Materials for the Battery of Tomorrow
Picture: Asahi Kasei

From 7 to 9 May, Asahi Kasei and its US subsidiary Celgard presented a wide range of high-performance materials for automotive batteries at the Battery Show Europe 2019 in Stuttgart, Germany.

A highlight at Asahi Kasei’s booth was the model of a lithium-ion battery, containing, among other things, high-performance plastics and separators. With this exhibit, the company demonstrates the range of its products for safe, efficient as well as compact structural parts and components for batteries.

This includes the high-performance plastic m-PPE (modified polyphenylene ether) as an innovative material solution for structural components of the battery housing. The m-PPE thermoplastic Xyron is electrically non-conductive and is characterized by its low density and resistance to electrolyte fluids. This makes it a suitable material for lightweight and compact battery housings.

With the m-PPE particle foam SunForce, Asahi Kasei offers a product that is distinguished by a high flame retardance (UL94 V-0), high formability and high thermal insulation properties. The engineering plastic thus contributes to the compact design of the battery housings and increases the safety and efficiency of the batteries. At the same time, the material is highly processable: The foam beads are manufactured with steam moulding. In contrast to other materials processed by injection moulding, tooling costs can thus be kept low.

In addition to m-PPE, the company – as one of only four fully integrated suppliers of polyamide 6.6 worldwide – presents the product grades SN and SG of the Leona PA 6.6 series as materials for battery components that contribute to reducing costs and weight.

Since Dr. Akira Yoshino, research associate at Asahi Kasei, developed the very first functional and safe prototype of a lithium-ion battery in the early 1980s, the company has been a pioneer in the field of lithium-ion battery research. As world market leader in lithium-ion battery separators, the Asahi Kasei Group is today considered as a substantial material supplier for the battery industry.

In order to meet the demand from the market for alternative packaging materials, the two companies Leipa Georg Leinfelder and Koehler Paper Group have developed in conjunction with Multivac a cardboard composite, which can be used for packing fresh food such as meat for example. This innovative solution based on paper fibre packaging material was presented at IFFA on the Multivacstand and run on a compact thermoforming packaging machine. The packs are designed in such a way, that the end user is able to separate the cardboard backing from the plastic barrier layer and then put it into the paper recycling.

Multilayer composite for skin packs

When developing this material, the challenge was to produce a cardboard composite with high barrier properties and a suitable sealing medium, which has the stiffness of a flat pre-cut card sheet but is also capable of being wound onto a roll, so that it can be run on a thermoforming packaging machine. The first results show that the Leipaflat multilayer composite is excellent at meeting all the requirements. This material can be used on a thermoforming packaging machine to produce skin packs, which not only package the product securely but also present it attractively to the consumer. As a strategic development partner in the board sector, Koehler provides Leipa with the material for manufacturing Leipaflat.

“Leipaflat is made of up to 90 percent renewable raw materials. Compared to the conventional packs used for these products, the features of this packaging material are its appearance and feel of a paper pack, and this contributes significantly to product differentiation in the chill cabinet,” explains Matthias Haux, Commercial Head of Flexible Packaging at Leipa. “This solution meets the high aspirations and demands of consumers, who are conscious of both quality and the environment. The cardboard offers not just the required stiffness, but it can also be run particularly well on thermoforming packaging machines thanks to its ease of winding on rolls. This solution can generally also be used on existing machines and dies. If requested, we are always willing to give customers advice on site about the optimum settings for their equipment.”

Danny Köppl, Product Manager for Films & Consumables at Multivac, adds: “This sustainable packaging solution, which was launched at FachPack 2018 and marketed under the Multivac PaperBoard range, has already received a very positive reception from professionals in the trade. Now we are receiving a large number of enquiries from the market, particularly against the background of the EU Plastics Strategy, and these are coming not only from Germany and Western Europe but also from many other regions such as Eastern Europe, North America and Oceania. We are currently carrying out a large number of sample productions for a wide range of customers.”

“We see great potential for this project, which has begun very successfully, and we are convinced that we can address the future of packaging in conjunction with our highly qualified partners, who embody the same collaborative ideas as we do,” says Dr. Markus Wildberger, Corporate Director of Technology at Koehler. “As part of our own ideas on sustainability, this project supports our aims of replacing plastics in packaging with paper-based materials, where it is sensible and practical to do so. This means that a product made from renewable raw materials is used, one for which closed-loop recycling has already been developed. We see in this and other collaborative projects the opportunity to develop and market further innovative solutions in the sector of flexible and rigid board packaging.” Dr. Wildberger also emphasizes that this could involve developments in the non-food as well as food sector.

“Based on today’s knowledge of the planned harmonisation of the EU regulations on plastic disposal, we assume that Leipaflat will lead to significant cost benefits in the context of the packaging fee for companies,” says Matthias Haux from Leipa. “And last but not least, the environment as well as consumers also benefit from this solution.”

PaperBoard

The PaperBoard portfolio comprises a wide range of solutions for producing MAP and vacuum skin packs from paper fibre-based materials. In conjunction with leading manufacturers, the company has developed suitable packaging materials, which can be run on standard machines. By using different functional layers, it is possible to produce packs from paper fibre-based materials, which also meet the barrier requirements of the most sensitive products. The packs can be designed in such a way, that the end user is able to separate the cardboard backing from the plastic barrier layer and then put it into the paper recycling.
