Introduction

When we talk about innovation and sustainability in the tobacco industry, one term that often comes up is reconstituted tobacco. This unique product has revolutionized the way tobacco is used and consumed, offering cost savings, flavor consistency, and more efficient usage of raw materials. But what exactly is reconstituted tobacco, and why has it become so important?

What is Reconstituted Tobacco?

Reconstituted tobacco, often referred to as “recon,” is a type of tobacco product made from the remnants of tobacco leaves. These remnants are combined, processed, and reformed into a sheet, hence the name “reconstituted tobacco sheet.” This process allows for a more efficient use of tobacco materials, ensuring that nothing goes to waste.

History and Evolution of Reconstituted Tobacco Sheets

The concept of reconstituted tobacco was invented in the 1950s. Its primary goal was to save valuable raw material by combining remnants of virgin tobacco during production. Over time, reconstituted tobacco has evolved, playing a crucial role in the tobacco blend design for products like cigarettes and cigars. It’s even been enriched with other components, such as cloves or hemp, allowing for the creation of entirely new products.

The Significance of Reconstituted Tobacco in the Tobacco Industry

Reconstituted tobacco has become a staple in the tobacco industry. This is not just due to its cost-effectiveness but also because of its versatility. It can be used to reduce the filling cost for cigarettes, cigars, pipe, and smoking tobacco blends. The advent of heated-tobacco products (HTPs) has given reconstituted tobacco leaf (RTL) a new lease of life. HTPs require a dedicated form of recon, custom-made from carefully blended tobacco leaves.

Advanced Production Techniques at RTF Russia

The tobacco industry has always been at the forefront of innovation, continuously seeking ways to enhance the quality and efficiency of its products. One such pioneer in this realm is the “RTF Russia”, a renowned plant in Russia.

Their state-of-the-art facility boasts an automated process for creating reconstituted tobacco, ensuring minimal operator intervention. This automation not only enhances the efficiency of the production line but also ensures the consistent quality of the final product. The meticulous procedure begins with the careful selection and filling of the dispenser with tobacco by-products. These raw materials undergo thorough sifting to prevent any clumping during the subsequent moisture application phase.

The fine grinding mill plays a pivotal role in breaking down the material, which is then directed to the calibration system. This system ensures that the tobacco by-products are of the desired consistency before they are stored. One of the standout features of RTF Russia's production line is the integration of a kitchen where liquid additives, such as propylene glycol and glycerin, are combined with water. This mixture is then blended with the dry components in a specialized mixing device. The proportion of each component is meticulously determined to achieve the desired characteristics of the final product.

Once the blending is complete, the mixture undergoes a drying process, resulting in a paste with a moisture content of 35-40%. This moisture level is optimal for conserving energy during the drying phase. The paste is then uniformly applied to a conveyor belt, forming an even layer, which is then transported to a multi-stage air-convection drying oven. The final product, reconstituted tobacco, is either shaped into 10x10 cm sheets or thin-cut fibers, depending on the desired format.

The packaging and weighing station is the final stop in this intricate process. The reconstituted tobacco is packaged according to industry standards, ensuring it's ready for shipment to customers worldwide.

Methods of Producing Reconstituted Tobacco Sheets

There are several methods employed in the production of reconstituted tobacco. Each of these methods has its advantages and unique characteristics.

Paper-Making Technique

This is one of the earliest methods used in the production of reconstituted tobacco. It follows a similar process to traditional paper-making, where tobacco remnants are blended into a pulp, spread out, and then dried to form sheets.

Nano Fiber Technology

This modern technique uses advanced technology to create nano fibers from tobacco remnants, resulting in a more refined and consistent product.

Band Cast or Slurry-Type Recon

This method involves creating a slurry from the tobacco remnants and spreading this thick mass onto a conveyor belt where it’s then dried. Despite its wide use, this method can present challenges in terms of space, energy, taste, drying, and tensile strength.

A Greener Future of Reconstituted Tobacco Sheets

In the quest to make tobacco use less harmful and more environmentally friendly, reconstituted tobacco sheets are gaining traction as a potential solution. The future of these sheets appears promising, with several advantages already evident. For instance, they contribute to a reduction in harmful chemicals released when smoked. This makes the product a healthier alternative compared to traditional tobacco leaf.

Embracing Technological Advancements

Tobacco companies are gradually turning towards technology to improve the quality of reconstituted tobacco sheets. By incorporating the latest technologies in the production process, these companies aim to increase the precision of nicotine delivery, hence enhancing the overall smoking experience.

Tobacco Leaves

Tobacco leaves are the main component of all tobacco products, including cigarettes, cigars, pipe tobacco, and chewing tobacco. These leaves are harvested from the tobacco plant and then cured, a process that involves drying and fermenting the leaves to develop their flavor.

There are many varieties of tobacco plants, and the leaves from these different varieties have distinct flavors and characteristics. Some of the most common types include:

  1. Virginia (or Flue-Cured) Tobacco: This type is the most commonly grown tobacco in the world. It is used in a variety of tobacco products, including cigarettes. It has a high sugar content and a light, sweet flavor.
  2. Burley Tobacco: This type is air-cured and has a lower sugar content, giving it a fuller, more robust flavor. It is commonly used in pipe tobacco and cigars.
  3. Oriental (or Turkish) Tobacco: This type is small-leaved and sun-cured. It has a distinctive spicy aroma and is often used in cigarettes, especially in blends.
  4. Perique Tobacco: This type is fermented in a unique process that results in a strong, powerful flavor. It is used primarily in pipe tobacco.
  5. Dark Air-Cured Tobacco: This type is used for cigars, dark cigarettes, and chewing tobacco. It has a strong, full-bodied flavor.

The quality of the tobacco leaves plays a significant role in the final product’s quality, affecting its flavor, aroma, and burn rate. The selection, curing, and blending of these leaves require a high degree of skill and knowledge.

Reconstituted tobacco sheets production

Raw Material Preparation

The first step in the production process is the preparation of the raw material. This can be tobacco, hemp, or clove, and it is first ground to a powder.

Creating the Dough

Moist components, including glycerin, water, and a binder, are added to the ground material to produce a dough. To stabilize the tobacco foil, cellulose microfibers are added. This is a differentiating step compared to the slurry process, which does not use cellulose microfibers.

Extrusion and Rolling

The dough is then taken into an extruder where it is pressed into pellets. These pellets are transferred into a rolling mill where under high pressure, rollers flatten it into an even paste before it is dried. This process ensures a uniform and controlled thickness, which is important for consistency and accuracy in the final product’s specifications, such as nicotine content.

Drying and Rolling

After being rolled, the tobacco sheet is dried. If used for heated tobacco products (HTPs) or wrapping cigars, the rolled recon sheet is wound on a bobbin. Optionally, it can be cut into flakes if intended as an add-back for the primary.

Further Processing

To further process the tobacco foil produced with this technology, a special cutting and rod-making process is recommended. It takes the recon sheet off the bobbin and cuts it into long, identical narrow strips. These strips can then be turned into rods for further combining of the final product.

Benefits of reconstituted tobacco sheets

Use of Remnants and Cost Efficiency

Reconstituted tobacco leaf (RTL) was initially invented to save valuable raw material by combining remnants of virgin tobacco during production. Today, it is primarily used to reduce the filling cost for cigarettes, cigars, or pipe and smoking tobacco blends.

Blend Design and New Product Creation

Reconstituted tobacco plays an essential role in cigarette blend design. It allows for the creation of completely new products when enriched with additives like cloves or hemp components.

Technological Advancements in Production

Technological advancements, such as the tobacco dust amalgamation (TDA) process, have improved the production of reconstituted tobacco sheets. The TDA process provides manufacturers with the option to produce reconstituted tobacco in-house instead of buying it from specialized suppliers, potentially leading to cost savings and greater control over production.

Enhanced Flavor Retention and Uniformity

The TDA process, in particular, allows for better retention of nicotine and flavor in the material. It also ensures a uniform and controlled thickness of the tobacco sheet, which guarantees consistency in downstream processes and helps to ensure that important product specifications, such as nicotine content, are always within the specified range.

Eco-friendliness and Energy Efficiency

Compared to other reconstituted tobacco production technologies, the TDA process uses significantly less water and energy, leading to reduced environmental impact. The drying process of the mass is significantly shorter, reducing energy consumption.
