Best air expansion tobacco stems
The best air expansion tobacco stems are those that have undergone a meticulous process to ensure quality and efficiency. The process involves turning green tobacco leaves into high-quality final products that meet industry standards. The tobacco leaves are hung in curing barns, where heated air is generated to dry the leaves.
Several varieties of tobacco are suitable for air expansion. For instance, the American 14 Tobacco is a Bright Leaf tobacco variety imported from Ukraine that is known for its drought tolerance and sunburn resistance. Each American 14 leaf can reach 30″ long and 15″ wide. Another variety, TN 86, is a medium-to-late-maturing cultivar that has more leaves and a more upright growth habit than other burley cultivars. It is the first burley tobacco variety with good resistance to TVMV and TEV diseases.
The quality of air-expanded tobacco stems can be influenced by several factors, including the size of the tobacco stems before and after air expansion, the moisture content of the tobacco stems, the quality of the tobacco leaves used, the efficiency of the air expansion process, the consistency of the final product, the shelf life of the air-expanded tobacco stems, and compliance with industry standards and regulations.
Air expansion process in tobacco stems
The process of air expansion in tobacco stems involves heating the stems under specific conditions to induce expansion. These stems, meticulously separated from the tobacco leaves, undergo heating under pressurized atmospheres with temperatures ranging from 150. to 300. C. This process is accompanied by the presence of superheated steam and lasts for a duration of 30 seconds or less. Subsequently, the pressure is rapidly released, resulting in the expansion of the stems. The resulting expanded stems can be shredded into cut tobacco stems or transformed into other tobacco products.
The process of air expansion encompasses a distinct set of processes involving the application of heat and pressure. Rapid release of pressure triggers stem expansion. By subjecting the stems to specified temperature and pressure conditions and subsequently releasing the pressure, tobacco stems possessing a truly exceptional smoking taste are born.
Air-expanded tobacco stems exhibit an improved filling capacity owing to their lower apparent density. This property allows for the augmentation of the volume of other tobacco materials without compromising the quality of the final product.
The science behind air expansion tobacco stems is based on the principles of thermodynamics. The pressure and temperature cause the tobacco stems to expand, resulting in a low-density, high-quality smoking material.
The high-temperature steam and venturi mechanism employed in the expansion process cause the stems to expand, thereby transforming the texture and flavor profile of the tobacco. The expanded stems are subsequently shredded and artfully combined with other tobacco products, ultimately delivering a smoking experience unparalleled in its uniqueness.
Quality of air expanded tobacco stems
The quality of air-expanded tobacco stems is determined by several factors, including the process of expansion, the moisture content, and the properties of the tobacco stems themselves.
The process of air expansion involves heating the stems under specific conditions to induce expansion. The stems are heated under pressurized atmospheres with temperatures ranging from 150. to 300. C, in the presence of superheated steam, for a duration of 30 seconds or less. The pressure is then rapidly released, resulting in the expansion of the stems. This process results in tobacco stems with an excellent smoking taste and improved filling capacity due to their lower apparent density.
The moisture content of the tobacco stems is also crucial for the quality of the final product. The stems typically have a moisture content of around 10% to 11% before the expansion process. The moisture content is then increased to at least 12% and more preferably to around 20% during the conditioning step. This step is carried out by contacting the stems with water steam, or a mixture of water and steam. The moisture content can be increased to 35% or less, more preferably 30% or less, to prevent damage to the stems during rolling.
The properties of the tobacco stems themselves also play a significant role in determining the quality of the final product. For instance, the strength of the tobacco leaf, which is dependent on calcium pectate, the cementing material in the cell wall, is an important factor in tobacco quality. Other quality parameters include total nitrogen content (1.0 – 3.0%), nicotine content (0.7 – 3.0%), total sugars content (10.0 – 26.0%), reducing sugars content (8.0 – 24.0%), and pH (4.6 – 5.5).
Thequality of air-expanded tobacco stems is determined by a combination of the expansion process, the moisture content of the stems, and the inherent properties of the tobacco stems themselves.
