PURPOSE:To prepare noodles having low water-content and excellent preservability and quality, without using a preliminary drying process, by kneading cereal flour with water using a twin-screw extruder having a specific screw structure, and extruding the mixture. CONSTITUTION:The screw of a twin-screw extruder is composed of a forward screw section, a kneading screw section optionally furnished with a reverse screw zone, and a forward screw section. The cereal flour is supplied to the twin-screw extruder through the feeding port, 15-35wt% water is charged through the water-inlet near the feeding port, and the materials are transferred forward to the kneading screw section with the forward screw under compression, heated to 65-85 deg.C by the shearing force and the heat transmitted from the heating jacket, etc., and processed for 30sec-3min. The processed dough is sent to the subsequent forward screw section, deaerated under reduced pressure, extruded in the form of noodle strings, cut to proper length, and dried to obtain the objective noodle. |
