The invention concerns a material (5) consisting at least partly of starch and/or starch-containing biomass and/or at least one starch derivative, and normally also including water (9) and/or alcohol. The material is homogenized and compressed in a feed and/or compression device (21), preferably a worm-gear (30). The paste-like material thus produced is forced into the hollow interior (39) of a gelling and/or mixing chamber (43) in which it is mixed with a cross-linking agent (51) and heated, melted and gelled by means of steam. This enables a highly homogeneous gelled mixture to be produced which can be further processed to give a wide variety of products, such as a transparent continuous strip (95) or a foam.
