[0002] Dehydrated vegetables refer to fresh vegetables that have been washed, dried, and processed to remove most of the water in the vegetables, while the original color and nutritional content of the vegetables remain basically unchanged. They are easy to store and transport, and can effectively regulate the off-season and peak season of vegetable production. When eating, they can be restored by soaking them in clean water, and the original color, nutrition and flavor of the vegetables are retained. During the processing of dehydrated vegetables, due to the transportation of different processes, some dried vegetables are crispy after dehydration, and their corners are easy to break, so they need to be screened out to improve the appearance of the finished dried vegetables and the convenience of packaging; The invention with the publication number CN211937743U discloses a dehydrated vegetable impurity removal conveyor crawler, the rotating shaft a and the rotating shaft b at the right end of the crawler are arranged on the bracket b, the bracket a is provided with a motor a and a motor b, the motor a is connected with the rotating shaft a to drive the outer crawler to rotate counterclockwise, the motor b is connected with the rotating shaft b to drive the inner crawler to rotate clockwise, and a plurality of impurity removal holes are arranged on the outer crawler. The invention has a simple and compact structure, is convenient for removing iron impurities in dehydrated vegetables, has a high impurity removal efficiency, and is very worthy of promotion and use in practical work; The invention with the publication number CN214487833U discloses a micro-vibration filter residue device for dehydrated dried vegetables. When the fan is running, the airflow is conveyed to the main body through the connecting pipe, the connecting cavity and the vents on the surface of the bottom cavity. The dried vegetables accumulated on the surface of the filter are screened by airflow from the bottom position of the filter. A part of the screened dried vegetables falls to the bottom of the main body, and a part is blown up by the airflow and falls on the conveyor belt to be transported and concentrated in the concentration cavity. The vents arranged in an "L" shape prevent the dried vegetables from blocking the vents. However, the above-mentioned debris recovery device for dehydrated dried vegetables still has the following problems during actual use: although the debris mixed inside the dried vegetables is screened and recovered by vibration, the dried vegetables are wrinkled and adhere to each other during the dehydration process, and some debris is mixed in them, making it difficult to screen out the mixed debris by vibration. At the same time, the sizes of dried vegetables vary, so it is difficult to effectively screen out the debris only by a unified sieve plate, which can easily cause omissions and low recovery efficiency.
