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 includes peach jelly extraction by nonpolar liquefied gas to obtain the specified extract; mixing of the tobacco materials with liquid carbon dioxide; its 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; separation of miscella and oil meal; slurring the oil meal in the aqueous solution of edible acid; introducing of edible polyalcohol in the liquor; its forming, drying till residual humidity of 13-15%; cutting and steeping in gas-liquid peach jelly extract and separated CO₂ miscella with simultaneous pressure increase; depressurising to atmospheric pressure with simultaneous freezing of soaked carbon dioxide and its distillation to obtain in the residue the target product.

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