Chestnut is usually harvested in September，thinking of chestnut, think of a bumper harvest, think of full fruits, the joy of autumn harvest.Chestnut has a high nutritional value, rich in a variety of trace elements, eating chestnut is helpful to strengthen the body, eliminate fatigue. Secondly, the vitamin C content of chestnut is higher than that of tomato, which is several times higher than that of apple. The carbohydrate content of chestnut is much higher than other nuts and dried fruits. It can effectively provide a lot of heat for the human body, help the metabolism of fat, and play a role in starvation tolerance and weight loss.But bad chestnuts that have been damaged by worms are difficult to sort out manually.Chestnut washing sorting machine produced by First Industry can classify the worm-damaged chestnuts automatically and quickly.

It is very important for producers and processors to determine the quality parameters of chestnut, especially in the chestnut post-harvest process . The quality of chestnuts sorted by chestnut classifier are higher than the unsorted products,so as to increase consumers' buying confidence.

One of the factors affecting the quality of chestnut is the existence of worms.The worms already exist in the growth stage of the chestnut, generally, worms leave the fruit by piercing the nuts after harvest in storage rooms or sale stands.Chestnuts with worm-damages and closed-holes are difficult to recognize without cutting or deforming the nut.So the human eye is very difficult to distinguish bad chestnuts.

Chestnut washing drying sorting machine can classify the worm-damaged chestnuts in the cleaning process. A special design is adopted for the cleaning pool of chestnut. Because the pulp of bad chestnut has been damaged by insects, its weight is lighter than ordinary chestnut, so it will float automatically during the cleaning process. In this way, the bad chestnut can be quickly sorted out without peeling it.Another bright spot of this chestnut classification machine is that it can grade the size of washed and dried chestnuts by size.

In general, chestnut cleaning and grading machine can quickly sort out the chestnut which is damaged by insects, and can also save labor costs. The most important thing is that the economic value of chestnut is further improved.
