With the improvement of technology, more and more farmers prefer to choose sorting fruit and vegetable with professional machine. There is no doubt that a suitable machine can save manpower, even take the place of manpower sometimes. But manual operation is still necessary for some parts on machine, especially the manual sorting for picking out bad fruit as below.

Take sweet potatoes for example, simple size sorting can surely not recognize the sweet potato with bad skin or weird shape. If don’t pick out these unqualified products in time and send them to the next step or to the market directly, may not only influence the quality but also the credit of a company. Thus an inspection table before size sorting is a good choice. 

With this function, workers can stand at 2 sides of the table, and put the bad sweet potatoes in the 4 holes. Then bad fruits are transferred to the conveyor belt below the inspection table and sent outside the processing line separately.

How to decide the length of inspection table? It depends on the quality of your original crops and the kind of crops you want to eliminate.
