what is stem tobacco and how is it different from other types of tobacco
Stem tobacco refers to the stem of the tobacco plant, which is used in various tobacco products. It has a similar chemical composition to tobacco leaves, but the content of different components is significantly different.
Stem tobacco differs from other types of tobacco in several ways. For instance, the processing and use of stem tobacco contrast with that of leaf tobacco used in cigarettes, cigars, and pipe tobacco. While leaf tobacco is often cured and finely cut for use in cigarettes, stem tobacco undergoes a different process.
The tobacco used in pipes and cigars also differs from stem tobacco. Pipe tobacco is generally more natural and less laden with chemicals compared to cigarette tobacco. It is usually sold in loose form or as pre-formed plugs or flakes. Cigars, on the other hand, are typically made by bunching together long-filler tobacco leaves, which are the interior leaves of the tobacco plant, and then rolling them in a binder and wrapper leaf .
In contrast, stem tobacco is typically used in a different manner. The stem of a tobacco pipe, for example, is a crucial part of the smoking apparatus. It defines the smoking experience in ways that are easy to overlook. The smoke will flow through the stummel and the stem before reaching your mouth, which is why the stem length has its importance..
what are the different methods of processing stem tobacco
Stem tobacco is processed through several methods, each with its unique steps and techniques. Here are some of the common methods used in processing stem tobacco:
- Moistening and Shredding: This method involves soaking the tobacco stems in water for a sufficient period to ensure the proper moisture content. The moistened stems are then shredded to a particle size suitable for use in cigarettes,
- Washing, Storing, Thinning, Cutting, and Steam Explosion: This process involves washing the stem, storing it, thinning, cutting the stem, and carrying out a steam explosion for the cut stem. The process is advantageous as it improves the color and shape of the cut stem and reduces the breakage rate in the cut stem process.
- Threshing: Threshing tobacco leaves forms a mixture of free lamina and clean stem pieces. This method is often used in the initial stages of tobacco processing.
- Pyrolysis: Pyrolysis is a technique used in processing organic waste into many beneficial materials. In the case of tobacco stems, they are cut into small pieces and put into closed pyrolysis equipment, and heated up to 450.C. The smoke is then distilled to obtain the tobacco bio oil.
- Curing: Curing is a process by which the harvested tobacco leaf is made ready for the market. It is a well-standardized process especially in FCV tobacco to achieve the desired quality.
- Conditioning: To make the leaves ready for the mechanical threshing process, harvested tobacco leaves are conditioned in cylinders to be more pliable using forced hot air and steam. The conditioned leaf passes through a series of mechanical threshers.
- High Temperature and High Pressure: One method to prepare the biomass material from stem granules utilizes high temperature and high pressure.
what are the main components of stem tobacco
Stem tobacco, which is the central stem of the tobacco plant, is composed of several key components. The major components of stem tobacco are cellulose, lignin, and hemicellulose.
Cellulose is a complex carbohydrate and the primary structural component of plant cell walls. The content of cellulose can be up to 40% for stem parts. Lignin is a class of complex organic polymers that form key structural materials in the support tissues of vascular plants. Hemicellulose is a type of plant material that, along with cellulose and lignin, contributes to the sturdiness of plants.
In addition to these, stem tobacco also contains other components such as nicotine and nicotine sulfate. Nicotine is a potent parasympathomimetic alkaloid found in the nightshade family of plants and is a stimulant drug. Nicotine sulfate is a potent insecticide derived from tobacco leaves.
Furthermore, the pyrolysis process of stem tobacco results in the production of various compounds such as CO, CO2, phenols, aldehydes, and ketones. Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. It involves the simultaneous change of chemical composition and physical phase, and is irreversible.
