Problems solved by technology

In the case of casting leaves which preferably have a high content of tobacco, this waste material contains a high percentage of relatively "expensive" components, so this resulting waste not only represents a loss of production due to large amounts of unused material, And it also represents a non-negligible waste

Embodiment Construction

[0060] initial reference figure 1 , presents a method for producing a slurry according to the invention. The first step in the method of the invention is the selection of the tobacco type and tobacco grade 100 to be used in the tobacco blend used to produce homogenized tobacco material. Tobacco types and tobacco grades for use in the methods of the invention are, for example, flue-cured, sun-cured, oriental and filler tobaccos.

[0061] According to the following steps of the method of the invention, only selected tobacco types and tobacco grades intended to be produced for homogenized tobacco material are processed.

[0062] The method comprises a further step 101 of laying the selected tobacco. This step may include checking tobacco integrity, such as grade and quantity, which may be verified, for example, by barcode readers for product tracking and traceability. After harvesting and curing, tobacco leaves are assigned grades, which describe, for example, stem position, q...

Abstract

The present invention relates to a method for the preparation of a cast sheet of homogenized tobacco material, said method comprising: pulping (108) cellulose fibres (5) with water (6); grinding (102,106) a blend of tobacco of one or more tobacco types to tobacco particles (10); combining (107) the pulped cellulose fibres with the tobacco particles and with a binder (8) to form a slurry; homogenizing the slurry; casting (110) the slurry to form a cast sheet of homogenized tobacco material from the slurry; discarding (112) undesired portions of the cast sheet; and introducing (113) the discarded undesired portions (9) of the cast sheet into the slurry.

Description

technical field [0001] The present invention relates to a method of making a cast sheet of homogenized tobacco material. Background technique [0002] Homogenized tobacco material is also used today in the manufacture of tobacco products other than tobacco leaf. Such homogenized tobacco material is generally produced from parts of the tobacco plant, such as tobacco stems or tobacco dust, which are less suitable for the production of filler tobacco. Typically, tobacco dust is produced as a by-product during the processing of tobacco leaves during manufacture. [0003] The most commonly used forms of homogenized tobacco material are reconstituted tobacco sheet and cast leaf. The process of forming a sheet of homogenized tobacco material typically includes the step of mixing ground tobacco with a binder to form a slurry. The slurry is then used to produce a tobacco web, for example by casting the viscous slurry onto a moving metal belt to produce a so-called cast leaf. Alte...
