If someone asks me what time is the best time to sort persimmons? I will say without hesitation: now.

Now is the stage at which persimmons can be picked after they are ripe: as the public is well-known, persimmons usually mature around October each fall. However, depending on the planted varieties, there may be some differences in the specific time. For example, yellow persimmons generally mature in late September, but another sweet persimmon only matures in mid-October.

The original intention of this persimmon sorting grading machine is based on the limited space used by the machine: as shown in the picture, about 6 workers can be used to pack the persimmons after weight sorting, and the most important thing is that we do it at the time of production. The diameter of this pattern tray has been produced as a standard configuration. That is to say, the diameter of the disc cannot be increased or decreased.
