METHOD OF PRODUCTION RECONSTITUTED TOBACCO Russian patent published in 2009 - IPC A24B3/14 

Abstract RU 2352203 C1

FIELD: tobacco industry.

SUBSTANCE: invention refers to the technology of tobacco refuse processing. The reconstituted tobacco production method includes eucalyptus extraction by nonpolar liquefied gas to obtain the specified extract. Tobacco materials are mixed with liquid carbon dioxide, extracted and blended together with periodical depressurising in the extraction mixture with pressure lower than of the moist steam of carbon dioxide at the extraction temperature. Miscella and oil meal are separated. The oil meal is slurred in the aqueous solution of the edible acid. Edible polyalcohol is introduced in the liquor, it is formed, dried till residual humidity of 13-15% and then cut. The cut material is steeped in gas-liquid eucalyptus extract and previously separated CO2 miscella with simultaneous pressure increase. Then the process of depressurising to atmospheric pressure with simultaneous freezing of soaked carbon dioxide and its distillation is carried out to obtain in the residue the target product.

EFFECT: improvement of reconstituted tobacco organoleptical properties, decrease of the duration of technological process.
