Method for producing a tobacco paste and reconstituted tobacco, tobacco-containing film, and system for producing reconstituted tobacco

Abstract

Method for producing a tobacco paste and reconstituted tobacco, a tobacco-containing film, film sections and films scraps, and a system for producing reconstituted tobacco. The method includes supplying a powdered material having a predefined particle size of less than 350 μm, wherein the powdered material comprises tobacco powder, supplying a highly viscous, water-based binder gel having a viscosity of at least 1000 cP, a water content of at least 50%, and at least one binder; and mixing the powdered material with the binder gel to form the tobacco paste that is substantially solid, wherein the tobacco paste has a water content or moisture content of at most 50%.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation of International Application No. PCT / EP2020 / 073702 filed Aug. 25, 2020, which claims priority to Italian Patent Application No. 10 2020 000000727 filed Jan. 16, 2020, the disclosures of which are expressly incorporated by reference herein in their entireties.BACKGROUND1. Field of the Invention[0002]The present invention relates to a method for producing a tobacco paste and reconstituted tobacco, to a tobacco-containing film, film sections and films scraps, and to a system for producing reconstituted tobacco.2. Discussion of Background Information[0003]In many alternative smoking products, in particular in so-called heat-not-burn products, the aerosol-forming substrate comprises reconstituted tobacco film. A particularly smooth and homogeneous tobacco film must be produced for use in the alternative smoking products. A known production method is disclosed, for example, in WO19086417. In a first production...

AI Technical Summary

Benefits of technology

This patent describes the use of additional powdered additives to improve the material properties of tobacco paste and tobacco film. The tobacco film has a width between 0.5 mm and 4 mm and a mass to surface area ratio between 0.08 mg / mm2 and 0.089 mg / mm2. The film has a homogeneous structure and good material properties for processing in the tobacco-processing industry. The patent also describes a gelling machine that generates a binder gel without water using binder, glycerin or propylene glycol, and a separating device for releasing a flat web of material with favorable material properties.

Problems solved by technology

This high moisture content results in high drying effort in downstream drying devices.

A disadvantage of this production method is the processing of a sludgy mass, which requires a large amount of energy in order to be dried.

If the tobacco paste is exposed to elevated pressures and / or elevated temperatures, the flavor and consistency of the tobacco paste are compromised.
