METHOD AND APPARATUS FOR MANUFACTURING RECONDITIONED TOBACCO MATERIAL Russian patent published in 2015 - IPC A24B15/24 

FIELD: tobacco industry.

SUBSTANCE: invention relates to a method for production of reconditioned tobacco material that includes extraction of natural tobacco material to produce sediment and liquid containing desirable components and undesirable components, fractionating treatment of the liquid by means of a reverse osmosis membrane to produce a fraction failing to penetrate through the membrane and containing desirable components and undesirable components and a fraction penetrating through the membrane and containing desirable components and undesirable components, liquid condition regulation during such fractionating treatment to maintain a temperature suitable for fractionating treatment, removal of residues from the liquid that precipitate in the liquid during fractioning treatment, preparation of reconditioned tobacco web and addition of the fraction failing to penetrate through the membrane into the reconditioned tobacco web; the liquid fractionating treatment fraction includes: repeated performance of fractionating treatment to obtain a concentrated fraction failing to penetrate through the membrane and a repeated cycle consisting of addition of process water into the concentrated fraction failing to penetrate through the membrane as well as fractionating treatment of the fraction failing to penetrate through the membrane with process water.

EFFECT: production of reconditioned tobacco material.
