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

FIELD: tobacco industry.

SUBSTANCE: invention refers to the technology of tobacco refuse processing. The method cherry jelly extraction by nonpolar liquefied gas to obtain the specified extract. The tobacco material is mixed with liquid carbon dioxide. The processes of extraction and blending together with periodical depressurising in the extraction mixture with pressure lower than of the moist steam of carbon dioxide at the extraction temperature are carried out. 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. The liquor is formed, dried till residual humidity of 13-15%, cut, steeped in gas-liquid cherry jelly extract and 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.
