Description

Technical Field

[0001] The present invention relates to the technical field of color sorters, and in particular to a multi-layer screening device for a mung bean color sorter. Background Art

[0002] Mung bean is a bean food consumed by people in daily life. It has rich nutritional value. People often consume mung bean in their daily diet, and mung bean can also be processed into a variety of snacks and drinks such as mung bean yogurt. After the mung bean is harvested, some mung beans are poorly grown during the growth process, and the mung beans are also moldy and defective during storage and transportation. Therefore, when the mung beans are processed into precise food, it is necessary to screen out the mung beans of poor quality mixed in a large number of mung beans. Usually, people use mung bean color sorters to screen a large number of mung beans. The working principle of the mung bean color sorter is based on the difference in the optical properties of the material. The photoelectric detection technology is used to automatically sort out the different-colored particles in the granular material. During the use of the mung bean color sorter, a large number of mung beans will flow downward in the feed channel. After the defective products mixed in a large number of mung beans are detected by the photoelectric detection equipment, the airflow blowing device is controlled to spray the fixed point of the airflow to screen out the defective mung beans mixed in the mung beans, and the screening operation of the mung beans is completed.

[0003] In order to ensure the efficiency of mung bean screening, the mung beans move downward at a faster speed in the mung bean color sorter. Therefore, after a single screening of a large number of mung beans, although most of the defective mung beans in the mung beans are screened out, some defective mung beans are inevitably mixed in the large number of mung beans after screening. Therefore, it is necessary to perform multiple screening operations on the mung beans to ensure that the defective mung beans in the mung beans are fully screened. It is inevitable that a small amount of high-quality mung beans will be mixed in the defective mung beans screened out multiple times. Therefore, when a large number of defective mung beans are accumulated, it is also necessary to screen out the high-quality mung beans mixed in the defective mung beans. Therefore, in the process of using the mung bean color sorter to screen a large number of mung beans, it is necessary to repeat the screening of the mung beans many times. However, if a large batch of mung beans is screened many times and then the mung beans are subjected to subsequent food finishing operations, it will cause other subsequent food processing equipment to be temporarily difficult to put into operation, affecting the overall processing efficiency of mung bean food.
