The invention relates to a household rice noodle
machine which comprises a base, a crushing, extruding and forming
system, a heating device and a driving
system, wherein the crushing, extruding and forming
system comprises an extruding and
grinding cavity, a screw rod and a forming die head; the heating device is used for heating the extruding and
grinding cavity; a feed inlet is formed in one end of the extruding and
grinding cavity while the forming die head is formed at the other end of the extruding and grinding cavity; the screw rod is located in the extruding and grinding cavity, and is sequentially provided with a material propelling section, a coarse crushing section, a fine crushing and grinding section and an extruding section along the direction from the feed inlet to the forming die head; the screw rod is integrally formed; grinding
helical teeth are uniformly distributed in the circumferential direction of the fine crushing and grinding section; grinding straight teeth corresponding to the grinding
helical teeth are formed in the extruding and grinding cavity; the grinding straight teeth are uniformly distributed on the inner surface of the extruding and grinding cavity; a grinding slot is formed between every two adjacent grinding straight teeth; and a grinding gap h1 is formed between each grinding straight tooth and the grinding
helical tooth. The household rice noodle
machine provided by the invention is provided with the screw rod and the extruding and grinding cavity which is matched with the screw rod, and rice noodles which are relatively good in taste and appearance are prepared.
