Abstract: A wet blend containing tobacco particles and a binder is 
extruded under conditions such that steam is generated within 
the material upon extrusion and effects foaming. To minimize 
the amount of water used, which may subsequently have to be 
dried off, the binder is pre-hydrated by mixing with water be­
fore being mixed with the tobacco particles. To improve the 
consistency of the hydrated binder a small proportion of tobac­
co particles can be mixed with the binder before hydration or 
part of the binder can be mixed dry with the tobacco particles, 
leaving an excess of water for admixture with the rest of the 
binder.
