Embodiment Construction

[0032] The device for carrying out the present invention is in figure 1 shown in . The extruder 1 shown has a drive mechanism 2 for a conveying screw 6 housed in the housing, with which the tobacco material is conveyed and compressed, which enters the extruder 1 at the position indicated by 3 middle. The screw 6 conveys and compresses the tobacco material until the tobacco material reaches the forming tool 4 on the right, where the tobacco material is discharged, for example via a self-opening and closing shear gap (Scherspalt), and is then extruded as a fibrous extrudate (Extrudat) 5 Provided for use in the manufacture of smoking articles. According to the invention, roughly in the center of the device, a heated process fluid 7 is introduced into the extruder 1 , wherein the fluid 7 (for example heated water) has previously been heated in the heater 11.

[0033] In the embodiment shown here, therefore, the humidity-conditioning medium or fluid 7 (for example water, steam)...

Abstract

The invention relates to a method for producing a smoking product from a tobacco material, wherein the tobacco material is treated using at least one extrusion process, which comprises compaction with an increase in pressure and temperature and a mechanical treatment and sudden flash drying of the material at an outlet of an extruder (1), wherein a heated process fluid (7) is supplied as a heat transfer medium to the tobacco material in the extruder (1) to supply process heat. The invention further relates to a device for producing a smoking product from a tobacco material using an extruder (1) which performs a compaction of a tobacco material with an increase in pressure and temperature and a mechanical treatment and sudden flash drying of the material at the extruder outlet, wherein the extruder (1) is associated with a heater (11), which heats a process fluid (7) that is supplied to the extruder (1) for supplying process heat as a heat transfer medium.

Description

technical field [0001] The invention relates to a method for producing smoking articles from tobacco material, wherein the tobacco material is produced by at least one extrusion process, and to an apparatus with an extruder for producing smoking articles from tobacco material. The present invention relates generally to the technical field of processing tobacco material in extruders. Background technique [0002] Moisture conditioning is an important step for many extrusion press applications, especially when dealing with natural substances (foodstuffs) containing starch and cellulose. Humidity conditioning refers to the adjustment of processing humidity with water or steam. These required tasks are usually performed in the preceding process / crew. In this case the ability of natural substances to absorb steam or water quickly and well is utilized. In this case, these units operate at ambient pressure. [0003] In another standard method, pre-wet material is typically disp...
