TEWS’ Take on Moisture Measurement and Weight Control

A look at some new offerings in the world of moisture- and density-meters to be presented at TABEXPO

A basic aspect of production quality, optimisation of energy consumption, and ecological digestibility is knowing the moisture content of the material.

For 20 years, TEWS-Elektronik has developed and produced modern moisture- and density-meters, utilizing the microwave method. Their special, patented measuring method, which delivers rapidly—and independent of product-density, tobacco-blends, color, and surface-variations—precise moisture signals.

The calibration of the system ensures stable, precise, and reproducible results both for process and laboratory applications. More than a thousand applications of this microwave moisture measuring technique in cigar-, cigarette-, filter tow- and filter rod factories throughout Europe, Africa, America, and Asia demonstrate the trust companies put in TEWS-Elektronik. Whether it be for the production of tobacco leaf, strips, stems, cut tobacco, gloves, cigarettes, cigars, filter tow, normal or multi- filterrods, a continuously high product quality can be improved with the help of this powerful measurement technique for the laboratory and production process.

The new Laboratory unit MW 4300 is especially suitable for the quality protection in the sense of the EU / ISO 9000 through extensive preparation, retention and print outs of statistical data.

Our smallest new device, the MW 1150 is applied for manual routine measurements at few products in a laboratory, because its functions are optimised on such tasks. Here a battery-option is possible for fast manual checks.

The cigarette test station MW 4420 measures the cigarette and filterrod- profile of density, moisture and cigarette-cut-position. The average-values can be correlated to lab oven for moisture determination of course, and also to any balance for tobacco weight. This unit typically is delivered pre-calibrated. A special version for Cigar-Profile Measurement for bigger diameters is available. Furthermore, another special version of the microwave resonator-technique can be applied together with a conventional filterrod- test station for mass-, pressure-drop and diameter-measurement, to determine the Plasticizers- Content (Triacetin) and Moisture of a fresh produced filterrods.

The process version MW 4260 with a planar sensor (see photo) is used for the inline moisture measurement at all positions in the primary. It can be built in between two conveyor belts (chute), directly in a vibration conveyor or in metering tubes. These units are applied behind bale-slicers, before and after DCC-Cylinders, dryers, conditioners or casing cylinders in pure or blended leaf- tobacco, stems or cut rag.

The online cigar- and cigarette- Microwave Weight Measuring Unit MW3010 is built in a cigar- or cigarette-maker instead of traditional nucleonic-mass measurement, to guarantee an long term stable tobacco rod mass. This weight signal is independent of moisture fluctuations or blend variations. In combination with an available weight-control system, every single- or double-rod maker can be equipped, without any restrictions and costs for handling of nucleonic material. Different rod-diameters between thin cigarettes up to thick cigars are possible. In combination with this sensor, an additional feature is possible with the non-tobacco Foreign Body Detecting System MW3020. Contaminated cigarettes can be detected online and rejected with this special extension of the microwave technique, with a high detection rate— at a position where no further contamination is possible.

Our brand-new Microwave Transmission Unit MW-T for tobacco- and filtertow- bales measures precisely and with high speed the average moisture of moving or static bales, with or without carton- or plastic- packaging. The main feature of this new moisture- measuring technique is the independence of the weight, density and dimension of the bale. Therefore an additional balance-measurement is not necessary. The calibration is easily performed by the operator himself, can be loaded from one device to the next.

All these devices are presented by TEWS-Elektronik at the TABEXPO 2007 (booth No A17 Hall 6) and furthermore at the presentation platform for exhibitors by André Tews, 27 Nov 11:00 a.m.


Sun Chemical to Unveil New Ink Range at TABEXPO

Sun Chemical is underlining its commitment to innovation and customer service within the tobacco industry with the launch of a new range of inks and varnishes at TABEXPO.

Due to the increasing number of global regulations that govern the marketing and packaging of tobacco products, manufacturers have to be more creative in order to maintain their market share. This has led to the growth of shorter-run, limited edition packs. This approach is more suited to the offset printing process, rather than the gravure process that has been used traditionally.

Urs Schlatter, Managing Director, Global Tobacco Centres of Excellence, Sun Chemical, said: “The global tobacco industry faces an increasing number of constraints to business globally. As more stringent guidelines relating to marketing and packaging come into force worldwide, tobacco companies face an increasing challenge to capitalize on their main asset: their brand.

“Sun Chemical’s new offset inks, which will be launched at TABEXPO, will allow printers to realize the benefits of shorter packaging runs. Their low-migration properties will help printers meet a higher number of global regulations, allowing brands to compete effectively in the international market.”

In addition, Sun Chemical will display a book of concept designs and special effects on its stand (Hall 6, Stand B100) that will encourage printers and end users to change the way they think about enforcing their brand integrity. The concepts use existing brands to show how their branding could be enhanced though the use of effects, such as texture, heat response, holograms, light response, etc.

As a single source supplier, Sun Chemical will also be showcasing its existing products and services. The company provides all types of ink requirements, from packaging to filter tips, as well as a range of services such as streamlining production processes to increase cost efficiency.

Further details about Sun Chemical’s new range of inks for the Tobacco industry will be announced at TABEXPO. Visit stand B100, Hall 6 for details.


ROFIN’s Multi-kW Lasers with Galvo Technology

More than 300 applications per year are processed in the application labs of ROFIN’s business unit CO2 systems. Nowhere else you will find more practical experience in laser processing of organic materials such as paper or polymers. The range of applications spans from classics as stripping cables or degating to innovative applications in the fields of packaging or forgery-safety.

CO2 laser sources like ROFIN’s StarShape series are particularly suited for laser processing of organic materials because of the good absorption properties. These laser sources cover a power range from 100 W to 2,500 W and are available with five wavelengths from 9.15 Ìm to 10.6 Ìm - a great advantage for optimization of processing different materials. These lasers are based on ROFIN’s proven CO2 slab technology and work without any gas circulation. They have a compact built-up and due to low-maintenance they excel in high reliability. All systems are available either with galvo technology or fixed optics. The combination of high power lasers in the kW range with galvo heads is still rare, although these laser systems have great advantages in flexibility and performance, compared to other methods like using plotter systems.


delfortgroup Offers New Cigarette Design Software, Presented at TABEXPO

At this year’s TABEXPO in Paris, delfortgroup will present the significantly enhanced 4.0 version of its software for cigarette design. A new feature is the ability to make predictions for smoking regimes other than the standardized ISO smoking regime. These can be defined with respect to puff volume and duration, and it is even possible to freely define the puff shape, so that the smoke yields for human puff profiles can be predicted.

ISO functionalities such as predicting tar and nicotine content as well as carbon monoxide output are retained, but they are enhanced by the possibility of making a puff-by-puff analysis—also for alternative smoking regimes. This provides detailed insights into the effects of various types of tipping paper perforation and cigarette paper composition.

Another new feature is a problem solver, which automatically chooses the right tipping and plug wrap papers or cigarette paper to achieve design goals with respect to ventilation and smoke yield. Several new parameters have also been added regarding the selection of cigarette and tipping papers, for example, the diffusion constant. Thus the software is not only useful for speeding up product development, but also serves as a research tool to predict the effects of various paper properties.

The new software can be downloaded at www.cigarettedesigner.com.
