Embodiment 1

[0060] In a laboratory at 40°C in a water bath, a mixture of Virginia tobacco, Burley tobacco and Oriental tobacco leaves was brought into contact with water and manually stirred for 30 min. The water soluble components are separated from the fiber fraction by mechanical pressing. It has a dry matter concentration of about 5%. The water soluble fractions were concentrated under vacuum to a dry substance concentration of 47%. Glycerin is added to the tobacco water soluble components to obtain about 20% by weight in the final reconstituted tobacco.

[0061] Simultaneously, the Virginia stems were contacted with water for 30 minutes in a water bath at 80°C. The water soluble components are separated from the fibrous fraction by mechanical pressing and discarded.

[0062] Tobacco lamina fibers and tobacco stem fibers with added water and 10% lignocellulosic slurry expressed as wt% of the extracted tobacco blend were mixed and transferred to a refiner. The fibers were refined f...

Embodiment 2

[0067] In a laboratory at 85°C in a water bath, a mixture of Virginia tobacco, Burley tobacco and Oriental tobacco leaves was brought into contact with water and manually stirred for 30 min. The water soluble components are separated from the fiber fraction by mechanical pressing. It has a dry matter concentration of about 7%. The water soluble components were concentrated under vacuum. Glycerin is added to the tobacco water soluble components to obtain about 13%-18% by weight in the final reconstituted tobacco.

[0068] Tobacco fibers with added water and 8% lignocellulosic slurry expressed as % by weight of the extracted tobacco blend were mixed and transferred to a refiner. The fibers were refined for about 17 minutes.

[0069] Tobacco fiber sheets were formed on a laboratory paper machine. Glycerin is added to the concentrated water soluble ingredients. A concentrated tobacco water soluble ingredient comprising glycerin is added to the tobacco fiber sheet by dipping i...

Embodiment 3

[0075] The various Virginia leaves were contacted with water in a laboratory at 85°C in a water bath with manual agitation for 30 min. The water soluble components are separated from the fiber fraction by mechanical pressing. It has a dry matter concentration of about 8%. The water soluble components were concentrated under vacuum. Glycerin or glycerin and propylene glycol are added to the tobacco water soluble components to obtain 7.5% to 21.8% by weight in the final reconstituted tobacco.

[0076] Tobacco fibers with added water and 8% lignocellulosic slurry expressed as % by weight of the extracted tobacco blend were mixed and transferred to a refiner. The fibers were refined for about 20 minutes.

[0077] Tobacco fiber sheets were formed on a laboratory paper machine. Add glycerin or glycerin and propylene glycol to the concentrated water-soluble ingredients. Concentrated tobacco water soluble ingredients including humectants are added to the tobacco fiber sheet by di...

Abstract

The subject of the invention is a reconstituted tobacco specifically suitable for devices that heat tobacco without burning it. The reconstituted tobacco comprising tobacco fibres, a tobacco aqueous soluble fraction and a humectant, in which the tobacco aqueous soluble fraction represents between 10% and 35% by weight of the dry matter of the reconstituted tobacco and the humectant represents between 8% and 50% by weight of the dry matter of the reconstituted tobacco.

Description

technical field [0001] The subject of the invention is reconstituted tobacco for use in a device for heating tobacco without burning it. Background technique [0002] Combustion and pyrolysis of tobacco within cigarettes result in the formation of many harmful components in the smoke. To avoid its formation, numerous heating devices have been developed. By way of example, mention may be made of applications with publication numbers WO2013 / 178769 and EP2644043, which describe such devices. In these devices, the tobacco is heated without burning it, which leads to the formation of an aerosol. Thus, this enables the smoker to inhale tobacco aroma while significantly reducing his or her exposure to harmful components. [0003] For these devices, conventional tobacco is not suitable. In fact, it is necessary to add a large amount of humectants, such as glycerin or propylene glycol, to the tobacco to generate an aerosol when the tobacco is heated. It is this aerosol that repl...
