Reconstituted tobacco sheets have become an essential component in the tobacco industry, offering a sustainable and cost-effective solution to utilizing tobacco waste. This article will explore the manufacturing process of reconstituted tobacco sheets, the materials used, and their applications in the industry. This article was prepared in collaboration with professionals in the business (more about their process and plant: reconstituted tobacco process).

What is Reconstituted Tobacco?

Reconstituted tobacco is a product made from tobacco waste, such as dust, stems, and leaf scraps, which are combined to create a uniform sheet of tobacco material. These sheets can then be cut and used as filler in cigarettes and other smoking articles, providing a consistent and high-quality blend.
Reconstituted tobacco sheets are produced from recycled tobacco dust generated during the manufacturing process. A typical formulation for 1000g slurry includes 852g water, 128g tobacco dust, 20g cellulose ether, and an optional 5% humectant. The cellulose ether concentration is approximately 2-3% in slurry and 12-14% in reconstituted tobacco sheets. The presence of long cellulose fibers can increase the strength of the foil.

Benefits of Reconstituted Tobacco Sheets

Reconstituted tobacco sheets offer several advantages, including reduced waste, cost savings, and a more consistent product. By reclaiming remnants of virgin tobacco remaining after manufacture, the industry can minimize waste and make use of otherwise discarded materials.

Manufacturing Process

Preparing the Slurry
The first step in the manufacturing process involves preparing a slurry consisting of tobacco dust, water, and other additives. The tobacco dust should have a mean particle size in the range of about 60 mesh to ensure a uniform sheet. Cellulose ether, a binder, is also added to the slurry to help form the sheet.

Forming the Sheet

Once the slurry is prepared, it is used to form a sheet of reconstituted tobacco material. This can be done using various methods, such as casting or rolling. The sheet is then subjected to a moisture reduction process to achieve the desired consistency.

Drying the Sheet

After forming the sheet, it is dried to reduce its moisture content and improve its mechanical properties. This can be done using various drying techniques, such as air drying or oven drying.

Cutting and Packaging

Once the sheet is dried, it is cut into the desired size and packaged for use in cigarette production or other smoking articles.

Materials Used in the Process

Tobacco Dust
Tobacco dust is a byproduct of the tobacco processing industry and is the primary component of reconstituted tobacco sheets.

Cellulose Ether

Cellulose ether is used as a binder in the production of reconstituted tobacco sheets, helping to form a cohesive sheet.

Humectants

Humectants, such as glycerin, can be added to the slurry to improve the sheet’s moisture retention and overall quality.

Quality Criteria for Reconstituted Tobacco Sheets

Key quality criteria for reconstituted tobacco sheets include low shrinkage upon drying, uniform appearance, high tenacity (tearing strength), sheet elasticity, and taste during smoking.

Design Flexibility and Production Efficiencies

SWM’s manufacturing process for reconstituted tobacco sheets allows for design flexibility and production efficiencies, enabling the creation of a consistent and high-quality product.

Environmental Benefits

Reconstituted tobacco sheets offer environmental benefits by reducing waste and making use of otherwise discarded materials.

Applications of Reconstituted Tobacco Sheets

Reconstituted tobacco sheets can be used directly in the tobacco blend in combination with other tobacco leaf materials to form a consistent and high-quality cigarette blend.

Challenges in Manufacturing

Despite the various processes for the preparation of reconstituted tobacco sheets, many difficulties are encountered in manufacturing these sheets, such as achieving uniform thickness and increased survivability.

Innovations in the Manufacturing Process

Innovations in the manufacturing process, such as the use of steam boxes for pre-drying the sheets or the addition of various additives, have improved the quality and homogeneity of reconstituted tobacco sheets.

Reconstituted tobacco sheet making machines

Reconstituted tobacco sheet making machines use a paper-making process in which water is drained from a fibrous slurry of tobacco particles to form a sheet that is subsequently treated and dried (https://patents.google.com/patent/EP2134203B1/en
). Companies such as Garbuio, an Italian specialist in primary machinery and part of the Hauni Group, have developed alternative technologies for making reconstituted tobacco sheets. Garbuio has designed a recon plant that works with what it calls the tobacco dust amalgamation (TDA) process, an evolution of the slurry technology. The raw material is first ground to a powder and moist components are added to produce a dough. Cellulose microfibers are added to stabilize the tobacco foil. The dough is then taken into an extruder where it is pressed into pellets that are transferred into a rolling mill. Under high pressure, rollers flatten it into an even paste before it is dried (https://tobaccoreporter.com/2021/02/01/recon-reconsidered/
).

How does it compare with traditional methods?

The TDA process developed by Garbuio offers several advantages over traditional methods of making reconstituted tobacco sheets. In contrast to the paper-making and slurry technologies, which require a high water content in the raw material, the TDA technology needs little water. This results in a more efficient drying process and a reduction in energy consumption. The TDA process also allows for greater control over the thickness of the tobacco sheet, as the roller spacing can be adjusted exactly. This guarantees consistency in downstream processes and helps to ensure that important product specifications, such as nicotine content, are always within the specified range .

About the TDA process.

The TDA (tobacco dust amalgamation) process is an alternative technology for making reconstituted tobacco sheets developed by Garbuio, an Italian specialist in primary machinery and part of the Hauni Group. The process involves grinding the raw material, which can be tobacco, hemp or clove, into a powder. Moist components, including glycerin, water and binder, are then added to produce a dough. Cellulose microfibers are added to stabilize the tobacco foil. The dough is then taken into an extruder where it is pressed into pellets that are transferred into a rolling mill. Under high pressure, rollers flatten it into an even paste before it is dried. The TDA process offers several advantages over traditional methods of making reconstituted tobacco sheets, including greater control over the thickness of the tobacco sheet and a more efficient drying process due to the lower water content in the raw material.

Flavor additives for use in reconstituted tobacco sheets

Flavor additives are used in reconstituted tobacco sheets to improve the taste and aroma of tobacco products. These additives can help to reduce the harshness, bitterness, and astringency of the tobacco, making it more palatable to consumers. Some flavor additives that have been found useful in reconstituted tobacco sheets include potassium sorbate, citrus pectin, citric acid and lactic acid. These additives are usually used in small quantities to enhance the flavor of the tobacco without overpowering it. The use of flavor additives in tobacco products is subject to regulation in some countries.
