Process of separating gluten from starch and other solids

Abstract

Abstract A PROCESS FOR SEPARATING GLUTEN FROM STARCH IN A PRETREATED DOUGH MADE FROM FLOUR AND WATER. A PUMP HAS AN INLET AND AN OUTLET AND A FIRST PIPE FOR LEADING THE PRETREATED DOUGH TO THE INLET. A SCREEN CONNECTED TO THE OUTLET BY A SECOND PIPE SEPARATES THE GLUTEN AND WATER. A THIRD PIPE LEADS THE WATER SEPARATED FROM THE GLUTEN FROM THE SCREEN AND A FOURTH PIPE LEADS THE GLUTEN SEPARATED FROM THE SCREEN. A PREFORATED PALTE LOCATED BETWEEN THE OUTLET FROM SAID PUMP AND THE INLET TO THE SCREEN IS PROVIDED THROUGH WHICH THE GLUTEN LUMPS ARE PRESSED BY THE AID OF THE WATER. A SECOND SERIES OF ELEMENTS AS ABOVE IS CONNECTED TO THE FOURTH PIPE AND ADDITIONAL SERIES AS DESIRED SIMILARLY CONNECTED. ADDITIONAL MEANS ARE PROVIDED TO SUPPLY WATER TO THE SECOND PIPES. THE GLUTEN WHEN PRESSES THROUGH THE RESPECTIVE PASSAGES IS FIRST GIVEN A SHAPE OF A THIN-WALLED TUBE OR BLISTER WHICH IS THEN TORN BY THE ACTION OF THE LIQUID UNDER PRESSURE INTO THIN THREADS OR BANDS WHICH AFTER THE GLUTEN HAS LEFT THE PASSAGES AGAIN COLLECT INTO LUMPS OF A POROUS SPONGE-LIKE STRUCTURE, SO THAT THE GLUTEN SHALL HAVE LARGE SURGBACES OF CONTACT WITH THE WATER, WHICH FACILITATES AND ACCELERATES REMOVAL OF THE STARCH GRANULES.
