Description

Technical Field

[0002] At present, rice noodles are strip-shaped and thread-shaped rice products made from rice as raw material through processes such as soaking, steaming and pressing. There are many varieties of rice noodles, which can be divided into row rice noodles, square rice noodles, corrugated rice noodles, silver thread rice noodles, wet rice noodles and dry rice noodles, etc. The production processes are similar, generally including: rice, washing, soaking, grinding, steaming, extrusion, re-steaming, cooling, drying, packaging, and finished products.

[0003] The Chinese patent with the publication number CN114431394A discloses a forming device for rice noodle production, including a device body, an extrusion cylinder is provided on the device body, a plurality of connecting rods are connected between the extrusion cylinder and the device body, a discharging mechanism is connected to one side of the extrusion cylinder, and the discharging mechanism includes a mounting cylinder, the mounting cylinder is connected to one end of the extrusion cylinder, a push plate is provided in the mounting cylinder, a plurality of chutes are cut in the mounting cylinder, a slider is provided in the chutes, the slider is connected to the push plate, a connecting pipe is connected to the push plate, a plurality of forming holes are cut in the push plate, the connecting pipe is connected to the plurality of forming holes, and a plurality of sliding rods are provided in the chutes. The invention effectively reduces the occurrence of rice noodles sticking together during the extrusion process by setting the corresponding structure on the rice noodle forming device, effectively reduces the probability of blocking the discharging port when the rice noodles are extruded, effectively improves the forming effect of the rice noodle forming device, and effectively reduces the waste of rice noodle raw materials.

[0004] Although the above patent can extrude rice noodles, the temperature of the rice noodles raw materials will gradually decrease during the extrusion molding process due to continuous transportation, which will cause the rice noodles to stick to the inner wall of the conveying path, causing internal blockage for a long time, and the temperature balance of the rice noodles transportation cannot be guaranteed. At the same time, the device cannot adjust the extrusion amount of the rice noodles, and cannot ensure that the extruded rice noodles have the same content, resulting in defects in the rice noodles, affecting the quality of the rice noodles. It cannot automatically detect and adjust, and the transportation stability is poor. The molds used for rice noodle extrusion are prone to mutual interference during the extrusion process, resulting in knots and sticking between the rice noodles, and the independent transportation of the rice noodles cannot be guaranteed, which has a serious impact on the subsequent rice noodle processing.
