RECONSTITUTED LEAF TOBACCO AND ITS PRODUCTION METHOD (VERSIONS) Russian patent published in 2009 - IPC A24B3/14 A24B15/12 A24B15/14 A24B15/24 A24D1/02 

FIELD: tobacco products.

SUBSTANCE: methods proposed refer to reconstituted leaf tobacco production, as well as to production of modified reconstituted leaf tobacco. The methods are designed for cigarette manufacturing. One of the version refers to method of reconstituted leaf tobacco with binder production. The method implies production of suspension from tobacco and binder in given correlation. Preliminarily produced leaf of reconstituted tobacco, containing given quantity of wood paste, is enveloped with the suspension obtained. The suspension is complemented with a flavouring agent. The reconstituted leaf tobacco is supplemented with wetting reagent. A leaf of reconstituted tobacco is sliced into stripes. Several such stripes are placed into cigarette so that the stripes are adjacent to tobacco core. The other reconstituted leaf tobacco production version implies manufacturing of suspension from binder, wetting reagent, tobacco and flavouring agent, following defined proportions. The suspension is produced by sequential dispersion of tobacco, binder, wetting reagent and flavouring agent in water solvent. Then leaf production technological procedure is as described above. It also refers to cigarette, containing tobacco core, which is wrapped into outer envelopment, as well as to incomplete inner envelopment, presented by one or several stripes, made from reconstituted tobacco leaf. The inner envelopment is placed along the tobacco core, between the latter and outer envelopment. It also refers to reconstituted leaf tobacco, containing wood paste, binder and tobacco in defined proportion. The method of modified reconstituted leaf tobacco production includes the following operations. First, tobacco particle suspension is prepared in water solvent. The suspension obtained is then subjected to extraction processing at temperature of approximately 160°F for a period of approximately 30 minutes. Then the suspension is divided into extract with components, soluble in water, and solid fraction, which is mixed with wood paste and formed into leaf of reconstituted tobacco, using Fourdrinier machine. The extract is centrifugated, concentrated, supplemented with first binder and wetting reagent, applied to leaf of reconstituted tobacco and dried. Afterwards, the leaf is processed as described above.

EFFECT: decrease of ignitability for smoking products with one-layer envelopment.
