This work involves a system for screening, cutting and disintegrating fruits and vegetables, especially a recycling and processing system for fruits and vegetables that will be eliminated or cannot be sold.

The remaining vegetables and fruits that have been eliminated from the market due to various reasons such as poor quality or cannot be sold can still be recycled. Specifically, the remaining large pieces of vegetables and fruits will be cut and disintegrated into small particles. After completion, they will be transported by transportation vehicles to specific places for processing or use. The disintegrated vegetables and fruits can effectively use the transportation space of vehicles. , in order to improve the overall transportation volume, and the small granular fruits and vegetables can be used for other applications, so that a large number of discarded fruits and vegetables can be effectively reused and resource waste can be reduced.

Such surplus fruits and vegetables have been transported and sold, and the environment is complex. Plastic ropes for packaging or various other non-metallic or metal foreign objects are often mixed in the recycled surplus vegetables and fruits. Therefore, foreign objects need to be screened out before cutting and crushing. However, the current foreign matter screening work can only be handled manually, resulting in a slow recovery and processing speed of the remaining fruits and vegetables, and metal foreign matter is likely to remain.

Therefore, the prior art apparatus for recycling and processing surplus vegetables and fruits and the method thereof need to be improved.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a system for recycling and processing surplus vegetables and fruits and a method thereof to improve processing speed and automatically screen out foreign metal objects.
