A method for continuously producing a conversion product, in particular starch glue, fried starch, dissolved gelatin or protein glue, wherein a starch-containing and/or protein-containing, preferably powdery starting material, in particular flour, starch powder, cereal grains, coarse cereal meal, gelatin powder or gluten powder, is fed to a mixing chamber (2) and the starting material, preferably powder, descending in the mixing chamber (2) is subjected to a liquid heated to a processing temperature (TU) of at least 50° C. for converting the starting material into the conversion product, in particular to at least a gelatinization temperature of the starch-containing starting material, a protein-dissolving and/or denaturing temperature of the protein-containing starting material or a frying temperature, in the form of a pressure jet (7) and is thereby conveyed against a baffle (10) preferably formed by an inner wall of the mixing chamber or by an installation in the mixing chamber.
