Embodiment Construction

[0055] Specifically, figure 1 A first embodiment of a device for obtaining a tobacco flavor extract is shown, generally indicated with the reference number 100 .

[0056] The apparatus 100 comprises a direct conditioning drum 10 suitable for conditioning a mixture of tobacco leaves, stems and blades in a tobacco primary manufacturing line.

[0057] In the direct conditioning drum 10, the dry mixture of tobacco leaves, stems and blades is exposed to heat and humidity to open and toughen its structure for further processing. For example, steam and hot water are sprayed in a counter-current fashion on a mixture of tobacco leaves, stems and leaves.

[0058] The direct conditioning drum 10 includes an exhaust pipe 20 . The exhaust pipe 20 is adapted to discharge emissions from the rehydrated mixture.

[0059] The device 100 also includes a condensation system 30 . A condensing system 30 is fluidly connected to the exhaust pipe 20 . The condensing system 30 is adapted to reduce...

Abstract

The present invention relates to a process to obtain tobacco flavor extracts, the process comprising: conditioning a mixture of tobaccos in a primary tobacco manufacture heating the mixture of tobaccoto a temperature comprised between about 30 degrees Celsius and about 90 degrees Celsius for a time interval comprised between about 30 seconds and about 1 hour; recovering emissions produced by themixture conditioning; and obtaining at least one flavor extract from the recovered emissions. The present invention also relates to an apparatus to obtain tobacco flavor extracts.

Description

technical field [0001] The present invention relates to methods and apparatus for obtaining flavor extracts, especially tobacco flavor extracts, for example for use in aerosol-forming articles. Background technique [0002] The sensory attributes of cigarette smoke can be modified by incorporating flavoring materials into different components of the cigarette. For example, capsules or beads may be incorporated in a component of a cigarette, such as a filter. Liquid flavorants are also known which may be sprayed or otherwise introduced into one or more components of the cigarette. In so-called electronic cigarettes, also known as e-cigarettes, flavorings are also known. Flavors can be liquid and added to the barrel of an e-cigarette. [0003] Tobacco flavors are one of the flavors that may be added to smoking articles. Tobacco flavors are used in particular in electronic cigarettes, for example to reproduce the smoking sensation of conventional cigarettes when using elect...
