Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a rice noodle raw material screening mechanism. Background Technology

[0002] Legend has it that long ago, in the Changbai Mountain region, there was a type of baby food called "Milk Cloth" or "Rice Powder." It was made by grinding germinated rice into a paste, spreading it on a cloth, and drying it on a volcanic rock slab. The dried rice flakes were then peeled off and ground into rice flour, which was then mixed with boiling water and consumed immediately. During the Wanli era, while Nurhaci was leading his army eastward to conquer various tribes in the Changbai Mountains, he suddenly fell ill with a throat ailment in Liuhe County, Jilin Province, refusing to eat or speak for several days. His condition became extremely critical, and doctors... The official was at a loss when, just then, the wet nurse happened to pass by carrying a bowl of "rice porridge." The official's eyes lit up, and in a moment of desperation, he gave the "rice porridge" to Nurhaci. Not only did his health improve, but his digestive system was also nourished, leading to a great victory over the nine-tribe coalition. This laid the foundation for his unification of the country. After unifying the Jurchen tribes, Nurhaci never forgot the life-saving "rice porridge." He ordered his subordinates to requisition large quantities of "rice porridge" from Liuhe to distribute to his soldiers, bestowing upon it the name "Ababu Enbol" (Manchu for "tribute rice noodles") and calling the wet nurse "Mi Jie" (Mi Jie). Over time, this gave rise to the basis of Chinese-style nutritious fast food. To ensure the quality of the rice noodles, the production process often requires screening.

[0003] A high-efficiency infant rice cereal screening device is disclosed in patent publication number CN210230591U. This patent includes a screening device body, with a vibrator positioned at the center of the top surface of the body. A vibration connecting shaft is connected to the output end of the vibrator, vertically penetrating the top surface of the screening device body and extending into the inner side of the body. A vibrating screening screen is positioned on the inner side of the body, near the vibrating connecting shaft. A feed pipe is located on the right side of the top surface of the body, within the body of the screening device. The side section is circular, and a discharge pipe is located on the bottom surface of the screening device. A vibrating screen allows for the screening of large quantities of rice noodles at once, filtering out substandard noodles. Multiple discharge ports at the bottom of the inlet pipe ensure the rice noodles are evenly distributed on the vibrating screen, effectively increasing work efficiency. The device allows for easy separation of the two tanks using a lifting ring, facilitating the cleaning of the screened rice noodles. The device has a simple structure and low cost, making it suitable for widespread use. However, the following issues exist in this patent:

[0004] The aforementioned rice noodle raw material screening device directly feeds a large amount of rice noodle raw material into the screening device for screening. The screening process involves high-speed rotation of the screen plate, which can easily cause the rice noodles to fly around, making the screening operation difficult. The rice noodle raw material is also prone to clumping, which can easily block the feed inlet and screen holes. The clumped rice noodle raw material remains directly on the screen surface, which not only makes the screening of rice noodle raw material difficult but may also lead to waste of rice noodle raw material.

[0005] To address the above issues, a rice noodle raw material screening mechanism needs to be designed to overcome these problems. Utility Model Content
