Description

Technical Field

[0001] This utility model relates to the field of rice noodle screening technology, and in particular to a screening device for rice noodle production. Background Technology

[0002] Screening devices in rice noodle production are key equipment for ensuring product quality and production efficiency. They are mainly used to grade and screen rice noodle raw materials, semi-finished products, and finished products, removing impurities, unqualified particles, or foreign objects. If material clumps occur during rice noodle production, or if unevenly sized noodles are produced during the extrusion process, they can be separated by screening devices to avoid affecting the appearance and taste of the final product. The rational selection and configuration of screening devices is an important foundation for rice noodle enterprises to achieve industrialized and large-scale production.

[0003] However, existing technologies, such as Chinese Publication No. CN214718233U, "A Screening Device for Rice Noodle Production and Processing," provide a screening device for rice noodle production and processing, including a screening chamber, a sieve plate, and a feeding chamber. The sieve plate is installed at the bottom of the screening chamber, and a distribution plate is installed on one side of the movable rod and the sliding rod. This invention, by setting up a screening mechanism, starts a third servo motor, which drives the drive gear to rotate. Since the drive gear is threadedly connected to the movable rod, it moves the movable rod, causing the sliding rod to move as well, which in turn moves the distribution plate to the right for feeding. Then, a first servo motor is started, which drives the eccentric wheel to rotate, causing the sieve plate to move up and down to screen the rice noodles. Finally, a second servo motor is started, driving the stirring rod to stir the rice noodles, accelerating the screening efficiency and greatly improving the practicality of the device.

[0004] However, this device does not have an adjustable vibration amplitude structure, so it cannot adapt to the screening needs of different production stages and different material characteristics. It cannot achieve more accurate screening by flexibly adjusting the vibration intensity. It is not suitable for screening rice noodles that are hard and not easy to break. It cannot make rice noodles pass through the screen quickly, which increases the residue of fine powder. It cannot process rice noodles that are soft or fine in size, resulting in a low yield. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to adapt to the screening needs of different production stages and different material characteristics, the inability to achieve more accurate screening by flexibly adjusting the vibration intensity, the unsuitability for screening rice noodles with a hard texture and not easy to break, the inability to allow rice noodles to pass through the screen quickly, resulting in increased fine powder residue, the inability to process rice noodles with a soft texture or fine specifications, and the low yield.

Then, the rice flour to be screened is placed inside the primary screening shell 25. The external power supply of the drive motor 21 is turned on. The drive motor 21 is fixed to the bottom of the adjustment plate 6 via the second mounting sleeve 20. After the drive motor 21 is powered on, it drives the rotating rod 14 and the follower bar 15 to rotate.
