‘Silica filter optimizes filtration’

| June 3, 2013

Solvay Acetow has launched Rhodia FilterSorb, a silica filter solution for optimized filtration.

A unique silica-based granule in a cellulose acetate matrix, Rhodia FilterSorb adds a second filtration step to a standard filter to provide optimized filtration, without loss of flavor, according to Solvay Acetoy.

In a qualitative taste panel, comparing a standard cellulose acetate filter, a charcoal filter and a Rhodia FilterSorb filter, most panelists found that Rhodia FilterSorb preserved more real tobacco flavor while providing a softer and smoother taste.

A survey performed in Russia showed that around 35 percent of the participants would be prepared to pay a significant premium for cigarettes with an improved filtration capability.

Ferrary to manage Rhodia Acetow

| January 28, 2013

Olivier Ferrary is taking over from Gérard Collette as general manager of Rhodia Acetow, which in 2011 became part of the Solvay Group.

A former manager of SDU Special Chemicals, Ferrary has held various responsibilities relating to chemicals and plastics within the Solvay Group. Collette will take over the management of Solvay’s industrial function and move to the company’s headquarters in Brussels.

During his tenure, Collette initiated projects to improve efficiency and diversify the company’s portfolio, which contributed to growth. Ferrary intends to continue this course.

Coinciding with the Solvay Group’s 150th anniversary in 2013, the company also released a new logo. The logo symbolizes the integration process, aimed at merging the two companies into a global player in sustainable chemistry.

Solvay offers a broad range of products in a variety of industries. Headquartered in Brussels, the group employs about 31,000 people in 55 countries and generated net sales of €12.7 billion ($16.82 billion) in 2011.

Rhodia Acetow is the world’s third-largest producer of cellulose acetate tow for cigarette filters. It has four production sites on four continents.

New technology improves filter performance and functionality

| September 19, 2012

Celanese Corp. has developed a technology that enables cigarette manufacturers to deploy filter additives at significantly higher loading levels than was previously possible.

CelFX Matrix Technology creates a firm, porous matrix structure that can hold a broad range of additives in the filters of cigarettes. As a result, the matrix structure efficiently filters the smoke stream while effectively introducing the loaded additives in the process.

According to Todd Elliott, vice president and general manager of Celanese Acetate Products, CelFX Matrix Technology raises filtration to a new level of performance and functionality.

At the core of CelFX Matrix Technology is an ability to employ various additives at significantly higher loading levels directly in the filter. Holding these additives strongly in place with a specialized inert binder material, CelFX Matrix Technology allows better filtration efficiencies and helps to free up filter space that can be used by product designers for other innovation.

Trials conducted with CelFX technology-based rods demonstrate that it is a drop-in solution for commercial combiner equipment.

“With the launch of CelFX technology, manufacturers now have a highly versatile platform to develop innovative products,” says Elliott.

“As advanced filtration becomes a focus of product innovation, Celanese is redefining filtration performance with CelFX Matrix Technology, effectively expanding the horizons of filter capabilities. The cigarette-producing industry may now rethink how it looks at advanced filtration.”

Hauni filter system improves efficiency

| September 14, 2012

Hauni’s new high-bay storage system allows cigarette manufacturers to separate filter making from the cigarette production process.

Hauni Maschinenbau is introducing a new all-automatic high-bay storage system that allows cigarette makers to separate filter making from the cigarette production process.

Apart from maximizing machine utilization, the system’s space-saving storage unit keeps filters ready for use wherever and whenever required.

“This storage system keeps the filter and cigarette manufacturing processes separate, allowing filter and cigarette makers to achieve optimum utilization figures,” says Patrick Fricke, head of customer project management engineering at Hauni. “A hitch on one machine won’t automatically bring the entire production process to a halt as it soon would with makers in a fixed link-up.”

When connected to a high-bay storage system, filter makers can be kept running for as long as required. They can even manufacture filters for several shifts in advance, thereby omitting the need for night shifts. This not only improves machine utilization but also dispenses with the need to keep switching from one filter specification to another.

Having a variety of rod types on hand gives manufacturers the flexibility to make smaller batch sizes. The variety in brands and cigarette formats has risen sharply in recent years, and this trend is likely to continue.

Another benefit is that the filters stored in this system have time to cure adequately, ensuring smooth processing during cigarette making.

Storage systems of this type can also help minimize errors in the manufacturing process, particularly when producing multifilters.

Part of Hauni’s system-integration concept, the storage system is supplied by Dematic of Germany.

The system is designed to work smoothly with Hauni’s tray fillers and dischargers. “Manufacturing companies can continue using their existing equipment without needing to buy extra machines,” says Fricke. “Also, existing trays can continue to be used.”

According to Hauni, storage systems installed at two Chinese production facilities operate in perfect harmony with the machines linked to them. Another system is currently being set up in America.
