Problems solved by technology
Suboptimal casting conditions and equipment can lead to inhomogeneity and defects in the cast web of homogenized tobacco
[0006] The heterogeneity of the homogenized tobacco web can lead to difficulties in the subsequent processing of the homogenized tobacco web in the production of aerosol-generating articles
For example, inhomogeneity can lead to tearing of the web or even breakage of the web during its manufacture or further processing
This in turn can (for example) cause the machine to stop
Furthermore, non-homogenized tobacco webs can create undesirable differences in aerosol delivery from aerosol-generating articles produced from the same homogenized tobacco web

Embodiment Construction
[0046] initial reference figure 1 and figure 2 , an apparatus for producing a homogenized web of tobacco material according to the invention is indicated and indicated with reference numeral 1 .
[0047] The apparatus 1 for producing a homogenized tobacco material web comprises a casting apparatus 2 and also further comprises a drying apparatus 3 arranged downstream of the casting apparatus 2 in the direction of movement of the homogenized tobacco material web and a winding coil downstream of the drying apparatus 3 Station 10.
[0048] The casting apparatus 2 comprises a casting box 4 into which the slurry forming the web of homogenized tobacco material is introduced, a pump 5 , a casting blade 6 and a first movable support 7 . The casting box 4 may have any geometric shape, and in the depicted embodiment it is substantially prismatic. If necessary, the temperature of the casting box can be varied during the casting process by means of casting box control means (not shown ...

The invention relates to an apparatus (1) for producing a cast web of homogenized tobacco material, said casting system comprising a casting box (4) configured to receive a slurry of said homogenized tobacco material and A casting web from which the slurry is cast; a first drying section configured to dry the casting web; a movable support receiving the slurry from the casting box by casting said cast web formed from material and transported to said first drying section; - a drum (8) configured to move said movable support and configured to allow said drum to communicate with said movable heat exchange between the moving supports; and - first temperature control means cooling the drum such that the movable supports in the position where the cast web is received from the casting box onto the supports The temperature difference between the temperature of the material and the temperature of the slurry in the casting box is between about 0°C and about 30°C.
Description
technical field [0001] The present invention relates to an apparatus for producing cast webs of homogenized tobacco material. More specifically, the present invention relates to an apparatus for producing cast webs of homogenized tobacco material for use in aerosol-generating articles such as cigarettes or products containing tobacco of the "heat-not-burn" type. 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 typically 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 handling of tobacco leaves during manufacture. [0003] The most commonly used forms of homogenized tobacco material are reconstituted tobacco sheet and cast leaf. Methods of forming sheets of homogenized tobacco material ge...
