METHOD OF PRODUCING RECONSTITUTED TOBACCO Russian patent published in 2009 - IPC A24B3/14 A24B15/18 

FIELD: tobacco industry.

SUBSTANCE: invention refers to the technology of tobacco refuse processing. The method consists in extracting common buckwheat flowers with liquid carbon dioxide and separating a respective miscella. Then the tobacco material is mixed up with liquid carbon dioxide, extracted and shredded by relieving periodically the pressure in the extraction mixture below the pressure of carbon dioxide moist steam at extraction temperature. The miscella and meal are separated. The obtained miscellas are joined. The meal is suspended in an aqueous solution of an edible acid. An edible polyatomic alcohol is introduced into the suspension and the material is formed and dried to a residual humidity of 13-15%. Then the material is cut and treated with the miscella mixture by raising simultaneously the pressure. The pressure is relieved to atmospheric one by freezing simultaneously the soaked up carbon dioxide and the latter is sublimed to obtain a target product in the residue.

EFFECT: improved organoleptical properties of the reconstituted tobacco and shortened duration of the technological process.
