RECONSTITUTED TOBACCO PRODUCTION METHOD Russian patent published in 2009 - IPC A24B3/12 A24B15/24 A24D1/18 

FIELD: tobacco industry.

SUBSTANCE: invention relates to tobacco refuse processing technology. Implementation of the proposed reconstituted tobacco production method is as follows: girasol bloom is extracted with liquid carbon dioxide to produce the respective miscella. Tobacco material is mixed with liquid carbon dioxide and extracted. Then the tobacco material is crushed with the pressure in the extraction mixture bulk periodically relieved to be below the saturated carbon dioxide vapour pressure at extraction temperature. After that miscella and meal are separated. The obtained miscellae are mixed. The meal is suspended in water solution of an edible polybasic acid supersalt; potable polyatomic alcohol is added to the suspension. Then the suspension is moulded, dried for residual moisture content to be 13-15%, cut and imbued with the miscellae mixture under increasing pressure. After that depressurisation is done to the atmospheric pressure level combined with the absorbed CO₂ freezing. Finally, sublimation yields the target product.

EFFECT: invention enables improvement of reconstituted tobacco organoleptical properties combined with reduced duration of the technological process.
