The present invention relates to method for production of a slurry for homogenized tobacco material, said method comprising:

Method for the production of homogenized tobacco material

The invention relates to a method for the preparation of a homogenized tobacco material, said method comprising: &#x2014;pulping and refining cellulose fibres to obtain fibres having a mean size comprised between about 0.2 millimetres and about 4 millimetres; &#x2014;grinding a blend of tobacco of one or more tobacco types to a tobacco powder having a mean size comprised between about 0.03 millimetres and about 0.12 millimetres; &#x2014;combining the pulp with the tobacco powder blend of different tobacco types and with a binder in an amount comprised between about 1 percent and about 5 percent in dry weight basis of the total weight of the homogenized tobacco material, so as to form a slurry; &#x2014;homogenizing the slurry; and&#x2014;forming the homogenized tobacco material from the slurry.

Homogenized tobacco material and method of production of homogenized tobacco material

The present invention relates to method for production of a slurry for homogenized tobacco material, said method comprising: &#x2014;Selecting tobacco of one or more tobacco types; &#x2014;Coarse grinding said tobacco; &#x2014;Blending said tobacco of one or more tobacco types; and&#x2014;Fine grinding said tobacco of one or more tobacco types.

The present invention relates to a method to produce a homogenized tobacco material for use in a heat-not-burn aerosol-generating article, comprising the steps of: &#x2014;selecting a first target value for a first tobacco characteristic, said first tobacco characteristic being reducing sugars and the first target value being comprised between about (8) percent and about (18) percent in dry weight basis of a total amount of tobacco present within the homogenized tobacco material; &#x2014;selecting a second target value of a second tobacco characteristic, wherein the second tobacco characteristic is one of total ammonia and total alkaloids; &#x2014;blending graded tobacco types so as to form the tobacco blend, each graded tobacco type comprising a predetermined amount of the first and second tobacco characteristics, so that the first and second target values of said first and second tobacco characteristics are obtained in said blend within a predetermined tolerance range; &#x2014;grinding said tobacco blend into a blended tobacco powder; &#x2014;forming a slurry comprising the blended tobacco powder; and forming a web of homogenous tobacco web from the slurry.

Method for producing a homogenized tobacco material, and homogenized tobacco material

The present invention relates to a method of preparation of a slurry for the production of a homogenized tobacco material, said method comprising: &#x2014;suspending a binder in an aerosol-former to form a suspension; &#x2014;creating a cellulose pulp from cellulose fibers and water; &#x2014;providing a tobacco powder blend; and &#x2014;combining said suspension of binder in aerosol-former, said cellulose pulp and said tobacco powder blend to form said slurry.
