TH34249A - The process for preparing foodstuffs by extrusion - Google Patents

Abstract

DC60 (18/09/40) The process for preparing food products by extrusion, where the first processed food is fed into the first section of the twin-screw extruder, the second food is fed into the second section of the twin-screw extruder, this section is dynamically separated from the first section. These materials are each processed independently in the section they belong to of the extruder. Both resulting masses are extruded, passing through at least one flange, and the extruded product or the finished product is cut. The process for preparing food products by extrusion, where the first processed food is fed into the first section of the twin-screw extruder, the second food is fed into the second section of the twin-screw extruder, this section is dynamically separated from the first section. These materials are each processed independently in the section they belong to of the extruder. Both resulting masses are extruded, passing through at least one flange, and the extruded product or the finished product is cut.

Claims (13)

1. The process for preparing consumables by extrusion involves the first nutrient being processed and fed into the first section of the twin-screw extruder; a second nutrient is then processed and fed into the second section of the twin-screw extruder, which is dynamically separated from the first section. These nutrient masses are each processed independently in their respective sections of the extruder. Both resulting masses are extruded through at least one flange, and the extruded product is cut. 2. A process consistent with claim 1 in which the first and/or second substance, containing 14 to 22% water, is further processed to obtain an expanded product. 3. A process consistent with claim 2 in which the cut expanded product is dewatered so that the water content is less than 5%. 4. A process consistent with Reserviment 1 in which a first and/or second substance containing 24 to 36% water is further treated to obtain an expanded or slightly expanded product. 5. A process consistent with claim 4 in which the slightly expanded or non-expanding cut product is transformed into shreds by rolling and twisting. 6. A process consistent with claim 1 in which the first and second substances are similar and are acted upon by each process in similar ways in which they belong. 7. A process consistent with claim 1 where the first and second substances are distinct and are acted upon by each process in different ways in which they belong. 8. A process consistent with claim 3 in which the masses of both substances in the process are made to pass through two similar flange faces or through similar holes of a common flange. 9. A process consistent with claim 4 where the masses of both process substances are forced through different holes of a common flange. 10. A process consistent with claim 4 in which the mass of the substance in the process is co-extruded. 11. The installation for process implementation compliant with Reservival 1 consists of a twin-screw extruder separated into two sections by a dynamic separation device, with at least one extrusion flange and at least one cutting device. 12. Installation compliant with claim 8 where the dynamic isolation device comprises a protective zone where the twin screw units are located in opposite directions. 13. Installation in accordance with claim 8 where the exit from the first section of the extruder straddles the protected area of the twin-screw unit (Clause 13, Figure 6).
