Description

Technical Field

[0001] The utility model relates to the technical field of sorting, in particular to a multi-level sorting device. Background Art

[0002] The sorting device is a mechanical device that uses the physical or chemical properties of materials to sort, separate, and automatically classify. It detects materials through sensors, uses advanced technology and algorithms to classify materials according to certain rules, and achieves the purpose of sorting and purification. It is widely used in food, chemical, metallurgy, mining, building materials and other fields. The sorting machine can greatly improve production efficiency and product quality and reduce production costs.

[0003] Grapefruit is a fruit that people like very much. It is fragrant, sweet and sour, cool and moist, rich in nutrition, and has high medicinal value. At present, after processing and cleaning, grapefruit needs to be sorted by sorting equipment for multi-level sorting.

[0004] Existing grapefruit sorting devices include screen drum type, round hole belt type and roller type. In actual use, grapefruits will fall into different areas due to their different sizes through the sorting device, thereby achieving the purpose of grading. However, the quality of grapefruits is often not distinguished by the appearance size, but mainly determined by the juice content. The larger the juice content, the better the quality of the grapefruit, rather than the larger the grapefruit, the better the quality. The larger the grapefruit, the flesh inside the grapefruit may also appear "dry and without moisture", and the same is true for small fruits. Therefore, it is difficult to ensure the quality of the grapefruits by grading them only by size. For this reason, a multi-grade sorting device is proposed. Utility Model Content
