Supercritical expansion processing method for drying cigarette

Abstract

The invention discloses a method for processing supercritical expansion of cigarettes dried in the air, which comprises the following steps: a. tobacco leaves are loosened and humidified to increase the water ratio and the temperature of the tobacco leaves so that the tobacco leaves are loosened and the moisture content is even, materials are added to humidify the tobacco leaves; b. the tobacco leaves are cut into leaf threads; c. the leaf threads are stored; d. the leaf threads are put into a dipping mangle to be dipped for 20 to 60 seconds; e. the loosening, storage and feeding are performed; f. the leaf threads are expanded; g. the cooling, resurgence and perfuming processes are performed; and h. the foreign matters in the expanded leaf threads are removed. The method can apparently reduce the tar content, meet the style feature of cured tobacco products, and increase the dried tobacco filing value, thereby reducing the usage amount of finished products of tobacco shreds, and reducing the formulation cost; moreover, the method sufficiently adopts the function of expanded tobacco shreds on the specific incense and the form of smoke gas; and the formulation structure has relatively high adjustability, thereby effectively adjusting indexes such as the incense, concentration, taste, comfort and the form of smoke gas, and improving the formulation usability.

Description

technical field [0001] The invention relates to tobacco leaf processing technology in the technical field of tobacco processing, in particular to a supercritical expansion treatment method for air-dried tobacco. Background technique [0002] Air-cured tobacco is an essential raw material for the development of blended cigarettes. For a long time, blended cigarettes have been the most popular type of cigarettes in the world. This is not only due to the wide range of use of mixed cigarette raw materials, which is convenient for expanding production, but also because a certain proportion of oriental tobacco, self-rib tobacco, etc. are added to the mixed cigarette raw materials, which can effectively reduce the tar content of cigarettes and reduce the mutagenicity of tar per unit dose Therefore, blended cigarettes are superior to flue-cured cigarettes in terms of safety, so that smokers can increase the safety of smoking while enjoying their unique fragrance. [0003] With the ...

Problems solved by technology

What this method adopts is the curing process method, and the air-dried tobacco obtained by the curing process method has a strong aroma intensity, which cannot meet the design requirements such as the style characteristics of flue-cured tobacco products, and the effect of reducing tar is not obvious at the same time, and the curing process method is adopted The filling value of air-cured tobacco is about 5.0cm3 / g, which increases the consumption of finished tobacco and increases the cost of formula

[0006] The traditional dry ice puffing treatment method is mainly suitable for middle and low-grade burley tobacco or domestic burley tobacco with dull aroma, rough smoke, strong strength, obvious pungent feeling, heavy Armonia miscellaneous gas and other quality characteristics. The types and grades of tobacco are limited, and the burley tobacco obtained at the same time has a relatively simple use function, and cannot better meet the development needs of Chinese-style cigarette products in terms of quality indicators such as aroma style and smoke shape.
