Abstract (en)
[origin: EP1033081A2] The expansion method has the foodstuff or tobacco material fed through an expansion zone containing a Laval jet (4), using a carrier stream (13) containing between 10 and 100 % steam, with the sound velocity obtained in the narrowest cross-section of the expansion zone. The carrier stream may be preheated to a temperature of between 100 and 300 degrees C. An Independent claim for an expansion device for a foodstuff or tobacco material is also included.
