Steel Yankee dryers have been operating since 2000, and in recent years, they have become the dominant trend in the tissue industry. At present, the estimated number of steel Yankee dryers in operation worldwide is almost 400 units.

However, to this day, there aren’t any official guidelines regulating their safe operation, proper inspection and maintenance. The National Board Inspection codes for pressure vessels (such as ASME, PED, CSEI, JIS etc.) regulate the design and construction of steel Yankees, but their domain ends with the delivery. End users often demand that SYD checks and services be performed according to TAPPI’s standards, pointing to the need for an internationally recognized set of guidelines.    

In 2015, Toscotec first put forth the idea of creating an official set of standard practices for steel Yankee’s operations. TAPPI has since entrusted the Yankee Dryer Safety and Reliability Committee - Steel Yankee Subcommittee with the task of creating a new TAPPI TIP (Technical Information Paper) dedicated to Steel Yankee Dryers. In parallel, Toscotec has played a key role in helping update the TAPPI reference book Guidelines for Safe Operation and Condition Assessment of Yankee Dryers, which includes both updated contents for cast iron Yankees and steel Yankees. These publications are expected to become available in 2019.

Toscotec North America’s Lead Technical Service Analyst, Troy Kapalczynski is Chairperson of TAPPI’s Steel Yankee Subcommittee. As he explained, “the subcommittee is composed of manufacturers and end users who collaborate to expand the knowledge of Yankee dryers and address key questions about what and how procedures should be done in order to safely operate, properly control and maintain one of the most important equipment of a tissue mill. We are working to give end users the answers they need to optimize their operations”.

Riccardo Pierini, Toscotec’s Customer Care & Yankee Dryer Service Manager, added, “The subcommittee runs a peer-reviewed, highly specialized and technical project. Specifically for steel Yankees, we addressed issues such as inspection guidelines and principles, non-destructive examinations, routine and non-routine inspections, warm-up and cool-down procedures, and boiler water chemistry. In addition, we also developed maintenance and repair practices among other operating and reliability guidelines. These are all fundamental questions for Yankee managers worldwide”.  

As the leading supplier of steel Yankee dryers worldwide, Toscotec is the leading provider of content for TAPPI’s Steel Yankee Subcommittee. In this respect, Toscotec North America’s Area Engineering Manager, Alessandro Rocchiccioli pointed out, “We have 18 years of experience in the design, manufacture, and operation monitoring and service of steel Yankee dryers. With over 200 references, we have TT SYD running across the globe under a wide range of different environmental, pressure and operating conditions. We want to share this experience with the entire tissue industry, because the market has confirmed that steel Yankees are the future and, as an industry, we need a clear regulatory framework, as cast iron Yankees had back in 1992”.

Celupaper S.A. successfully started up PM4, a new MODULO-PLUS tissue machine supplied by Toscotec, at its Papelera Nicaragua mill, Argentina. The tissue machine started producing sellable paper immediately after start-up and is scheduled to reach the target speed in the following weeks, after careful fine-tuning.

The new MODULO-PLUS produces 65 tpd and it features a single layer TT Headbox, TT SuctionPressRoll, TT SYD-3200MM, TT Milltech-MYH monosystem gas-fired hoods. The scope of supply also includes the approach flow system, the electrification & control system, training, erection supervision, commissioning and start-up assistance.

PM4 is part of a series of repeated orders awarded to Toscotec by the leading South American tissue producer. In 2015, the Italian manufacturer carried out the rebuilding of PM2, an existing Fourdrinier machine, and supplied a new steel Yankee dryer TT SYD-2500MM and the complete steam and condensate system. In 2016, Toscotec supplied PM3, a complete MODULO tissue line.

Mario Speranza, CEO of Celupaper S.A. says, “Thanks to the continued production increase implemented with Toscotec’s plants, we have grown significantly in the South American market. Since 2015, we boosted production by over 100 tpd. Tissue quality, machine efficiency and energy reduction are our key standards of investments in new equipment. Throughout 4 years of close partnership with Toscotec, we have achieved good results with respect to all of these aspects and have continuously improved such results”.

“PM4 project evinced once again the excellent cooperation we have with Celupaper. With every new project, we aim to improve their performances. We worked intensively together on the reduction of energy consumption, starting from the design, with our TT DOES solution (Drying Optimization for Energy Savings) all the way to the fine-tuning of the plants at the mill site. On PM4, we also optimized the layout of the electrical and auxiliary plants, to guarantee better access for the operators to the different areas of the machine" commented Toscotec’s Project Manager Pier Paolo Brunazzi.

Toscotec launched its latest innovations during iT’s Tissue 2018. The advanced technologies it presented at its NOWNEXT open house include: Toscotec’s S-Crescent Former and the new TADVISION^® machine. 

The S-Crescent is a high efficiency forming section, which significantly increases dryness before the pressing area, through optimized dewatering. The aim is to reduce the burden of water removal for the press and consequently the drying section, by boosting dewatering in the wet section of the tissue machine.

Drawing on the experience of its successful installation in the U.S. market in 2004, Toscotec entirely redesigned its TAD machine to achieve superior tissue properties, including bulk and absorbency, and outstanding results in energy consumption. The new TADVISION^® ensures improved runnability and machine efficiency thanks to its unique serpentine TAD section, composed of three TAD honeycomb coated drums. A detailed Computational Fluid Dynamic analysis ensures a highly optimized airflow in the air-system ducts leading to the TAD section and Yankee hoods. Overall, TADVISION^® ensures a more effective use of energy, bringing consumption down to 4.5-5.5 MWh/ton, a significant decrease compared to the consumption of current TAD machines, which is estimated in the range of 6.0-7.5 MWh/ton. Toscotec is continuing its energy reduction program and is committed to further reducing the overall consumption to less than 4.5 MWh/ton for a plant of the same production capability over the next few years.

The other advanced technologies presented at Toscotec’s NOWNEXT open house include new upgrades of Toscotec’s rewinding line, TT WIND-H and TT WIND-L, and an overview of Toscotec’s excellence in tissue drying, with TT SYD and the Yankee Hood and Air System plants. In particular, Toscotec’s rewinders feature improved performances through a newly perfected automatic web tension control, fast cycles, operator friendly automation and the automatic shaft handling system. The Energy and Environment department presented the most comprehensive range of drying configurations presently available in tissue making, designed to suit all needs and operating conditions, with state-of-the-art heat recovery technology, including up to six energy recovery stages in one single plant.

Finally, Toscotec’s YES (Your Expert Service) division launched its 24/7 service catering for customers round the clock all over the world, with a very special tool, YES – CONNECT-VISION, the new helmet enabling fully integrated communication and problem-shooting excellence.

This year visitors concluded their experience of NOWNEXT open house in the newly inaugurated canteen, a brand-new building within the expanded perimeter of Toscotec’s headquarters, which includes recreational space for employees, such as a fitness center and two lounges.

Toscotec fired up other two AHEAD-2.0L PRODERGY tissue machines at APP’s OKI mill, in South Sumatra, Indonesia.

Following the start-up of two AHEAD-2.0L PRODERGY at Perawang mill earlier this year, these two OKI machines started production in less than 3 months after the start-up of the first of a series of Toscotec’s PRODERGY machine ordered by Asia Pulp & Paper (APP) for its Perawang and OKI mills in Indonesia. In the next few months, other four machines will start up at the same site.

The AHEAD-2.0L PRODERGY is Toscotec’s top of the line tissue machine, featuring 5.6 m width, 2,000 m/min operating speed, a second-generation steel Yankee dryer of 22 feet diameter and steam-heated hoods. Toscotec’s TT SYD-22FT is the biggest steel Yankee dryer ever manufactured in the world for tissue application. Toscotec’s energy saving innovations consolidate OKI mill’s optimized green process: the paper mill is fully integrated with a massive pulp mill of 2.8 million ton/yr estimated output.

Equipped with the most advanced environmental technology presently available, OKI production base is very much green-oriented. The mill will be powered by clean and self-sufficient energy generated from the pulp production process and wood bark gasification. Tissue production guarantees the highest standards in terms of tissue machine’s efficiency and energy consumption reduction, thanks to PRODERGY’s technological advantages.

Toscotec’s Chief Customer Service Officer Valter Di Nardo commented, “The erection, commissioning and start-up of OKI tissue machines was completed in record time. Toscotec’s technical team on site installed the first foundation plate on January 4. After just over one hundred days, we fired up the first AHEAD-2.0L PRODERGY, and after one week, the second start-up followed suit. The mill expressed satisfaction for tissue quality starting from day one”.

Toscotec was selected to rebuild the dryer section of Papertech PM 1 at Tudela mill, Spain. The customer has recognized Toscotec is the right partner to provide the best technology available in the drying process and to accomplish the company targets.

The ambitious aim of the project is to improve the actual gross production, by overcoming several constraints by intelligently applying Toscotec’s Steel Dryer technology and its features. The base project goals were: increasing the production, by maintaining the same length of dryer section, and drying a wider paper sheet with the same dryer face length.

The scope of supply will be on a turnkey basis, confirming once more the consolidated skill of Toscotec to manage complex projects and coordinate all the involved parties.

With this achievement, Toscotec will strengthen its reputation for being an all-round partner for Paper and Board manufacturers.

A key factor of the dryer section modification is to replace completely the last four sections with TT SteelDryer technology, thus resulting in 20 new TT SteelDryers with increased diameter and drying face width. The scope of supply also includes TT AirTail, an advanced rope-less tail threading system, specifically designed for low speed and high basis weight.

Toscotec’s service specialists will provide erection, supervision, commissioning and start-up assistance.

Delivery is forecast within the end of 2018, with start-up at beginning of 2019.

The scope of supply also includes erection supervision, commissioning and start-up assistance, as well as onsite training programs on operation and maintenance.

With this new double reference, Toscotec enters the growing Philippine market and strengthens its undiscussed leadership as global manufacturer of steel Yankee dryers.

About Cartiera di Pietramelara

Located in the province of Caserta, Cartiera di Pietramelara mill belongs to the Italian tissue producer Paperdi srl. Since 1989, the mill has been producing tissue products such as industrial rolls, kitchen rolls, toilet jumbo rolls and towel tissue, with the household brand “Soavex” and the professional brand “paperdi”. The current annual production is 45,000 tonnes. Inspired by a strong ecological mission, Paperdi mainly utilizes recycled materials to reduce the environmental impact of the manufacturing process.

Since its inauguration in 2016, this fully integrated plant has been operating at full capacity, implementing the entire production cycle of Toscotec’s TT SYD, from metalworking, precision mechanical machining to thermal treatment and surface metallization, up to non-destructive tests and certifications.

The sixteen TT SYD that are presently under construction feature different sizes, with diameters ranging from 3,650 mm to 6,705 mm and width from 3,100 to 6,050 mm. Toscotec has been manufacturing the world’s largest diameter steel Yankee dryers and their demand has been steadily going up to this day: 50% of the TT SYD currently under construction have diameters from 18 to 22 ft. In view of this, the strategic choice of the Technology Lab’s location offers a clear logistical advantage, by ensuring that large diameter Yankees get easy access to the seaport for expedite shipping operations.

The market’s demand for medium and large diameter TT SYD is far-reaching around the globe. The orders for these sixteen Yankee cylinders come from paper mills situated across four continents: Asia, North and South America, Europe and Africa, with Asia and the Americas together taking the lion’s share.

Toscotec sustained operations in the manufacturing of TT SYD are testament to the success of Toscotec’s design, including large diameter Yankees. Feedback from the first installations of 18 ft Yankees and of 22 ft Yankees have been of substantial improvements in drying efficiency, attracting paper mills to the opportunity of cost savings. Toscotec’s global market share of steel Yankee dryers exceeds 60% and nearly all new steel Yankees currently installed in paper mills in Western Europe are Toscotec-supplied.

Parallel to the success of its manufacturing operations, Toscotec is relentlessly striving for new breakthroughs with its R&D division. Following the engineering of the second generation TT SYD in late 2013, with improved rib design and metallization, as well as increased thermal exchange, Toscotec’s steel Yankee dryers are now looking into the future with their third generation’s design, which will be presented later this year.

Toscotec’s steel Yankee dryer TT SYD-18FT was successfully fired up at Fujian Jinmin Reconstituted Tobacco Development Co., Ltd., a subsidiary of China National Tobacco Corporation, at its Luoyuan mill, Fujian, China. The TT SYD reached top performance immediately after start-up at the end of March.

The advantages of TT SYD can benefit all grades and types of paper, not least reconstituted tobacco paper. After Toscotec’s successful reconstituted tobacco application in the U.S., the Chinese reconstituted tobacco paper producer Fujian Jinmin is now operating a big diameter TT SYD, which guarantees top drying efficiency at the lowest possible consumption cost.

From the delivery of the first TT SYD in 2000 throughout 18 years of successful and safe applications and two generations of design, this achievement further reinforces Toscotec’s position as the number one supplier of steel Yankee dryers worldwide. The number of TT SYD sold in five continents around the globe has recently reached more than 200 units, way ahead of the competition. Based on its ever-growing experience, Toscotec has constantly been upgrading its design and it is currently in the process of honing the third generation of TT SYD.
