Description

Technical Field

[0001] This invention relates to the field of flour processing technology, and in particular to a double-headed noodle extrusion molding machine. Background Technology

[0002] Noodle extrusion molding is a noodle-making technique that involves placing flour in a specific extrusion device and applying pressure to shape it into noodles through a die. The core of noodle extrusion molding technology lies in using mechanical force to compress dough into noodles of a specific shape and size. The dough is subjected to uniform pressure in the die, forming a continuous stream of noodles as it passes through the die holes.

[0003] In practical applications, noodle extrusion molding technology is widely used in the production of various types of noodles. For example, corn noodles, due to the special properties of their raw material (coarse grains have poor stickiness), are difficult to shape using traditional hand-making methods. Therefore, they are often forcibly extruded under high pressure and rapid cooking conditions using large machines and special molds. These noodles are characterized by high density and a chewy texture, making them very popular with consumers.

[0004] Existing noodle extrusion technology typically has only a single channel, resulting in low extrusion efficiency. Furthermore, flour in the storage bin tends to stick to the inner wall, and prolonged lack of cleaning can easily obstruct equipment operation, requiring maintenance. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses a double-head noodle extrusion molding machine, which effectively solves the problems in the background art. During use, this invention employs a double-head extrusion discharge design, increasing the noodle processing capacity. Each head can operate independently, activating different numbers of extrusion channels to meet varying needs. The device's internal storage is equipped with a reciprocating stirring mechanism, enabling thorough stirring of all flour within a large space. A cleaning mechanism is also provided on the arc-shaped surface of the base plate, effectively preventing dough sticking to the arc surface. The device features a two-stage extrusion mechanism, with each extrusion mechanism having a different pitch of either a wide or narrow threaded rod, resulting in varying extrusion force and a different degree of dough fineness. The gradually changing thread spacing on the wide or narrow threaded rods allows the dough to experience progressively increasing extrusion force during the extrusion process, achieving a gradual and progressive effect, resulting in finer and more uniform dough at each stage of extrusion.

[0036] Working principle: When using this invention, the premixed flour is first poured into the feeding trough 1. The pouring position is determined by the number of channels actually activated. If all channels are activated, pour into the middle; if only one channel is activated, pour into the top of that channel. Then, the stepper motor I11 is activated, driving the transmission shaft I2 to rotate, thereby driving the mixer 4 to stir the flour. At the same time, the stepper motor II12 is activated, driving the lead screw 7 to rotate, thereby driving the square slider 6 to slide back and forth. This, in turn, drives the ring slider 3 to slide back and forth through the limit rod 5, so that the mixer 4 can move its position while stirring, thus making the stirring more uniform. When mixing, the stepper motor Ⅲ16 also starts and rotates. The threaded conveyor rod 9 can drive the bottom flour conveyor to carry the flour out. The flour falls into the upper cylinder 21 through the hopper 29. If there is a non-starting channel, the cylinder 32 on the non-starting channel will drive the hopper 29 to rotate, thereby blocking the hopper 29 and preventing dust from entering the upper cylinder 21. When flour enters the upper cylinder 21, stepper motor VI 26 starts, driving the wide threaded rod 27 to rotate, thus initially extruding the flour to form dough, which is then extruded from the discharge pipe 22 into the lower cylinder 23. Subsequently, stepper motor V 25 starts, driving the narrow threaded rod 28 to rotate, further extruding the dough, which is then extruded through the fine holes on the noodle discharge cover 24, ultimately forming noodles.
