The process of manufacturing RTS uses a paper-making machine in which water is drained from a fibrous slurry of tobacco particles . Once prepared, these sheets may be cut in a similar fashion as whole leaf tobacco to produce tobacco filler suitable for cigarettes and other smoking articles .

The production of RTS involves several steps. First, an aqueous slurry containing tobacco material is prepared. A sheet is then formed from the aqueous slurry, followed by reducing the moisture content of the sheet to less than about 50% by weight. An aerosol former is incorporated into the sheet at a temperature below about 40.C, followed by drying the sheet .

Recon Tobacco Sheet Production Line By Rolling is one complete group of equipment which makes full use of tobacco waste such as tobacco stems, powder, and dust etc. produced in the cigarette manufacturing process. It adopts a special technical recipe and flow to finally remake the waste into tobacco Sheet filament. This system mainly consists of a vibratory conveyer, drying & crimping cylinder, cooling cylinder, vibratory sieving conveyer, weighing scale etc. It completes the working procedures of second time drying, crimping, cooling, shape forming of recon tobacco, and scaling of finished product for packing .

In terms of quality control, the NDC Technologies TM9000 Tobacco Gauge is combined with an NDC Technologies Gamma Gauge to achieve key measurements in the process. This powerful combination enables the producer to achieve greater process insight while closed-loop integration of the NDC Technologies solutions achieves automated process control, for consistently within-spec product batch after batch .

Despite the various processes for the preparation of reconstituted tobacco sheets known in the art, many difficulties are encountered in manufacturing these sheets.
