After fresh chestnuts are dried in the sun, they are put into an altar-shaped container, and then an appropriate amount of dry yellow sand is poured in, and the ratio of yellow sand to chestnuts is about 3: 1. Sprinkle some water on the surface of the yellow sand to prevent the water in the fresh chestnut from completely evaporating. This can also better realize the function of storing chestnuts.

2, ventilation and preservation

Fresh chestnut is not easy to deteriorate in a relatively ventilated environment because of its growth habit. When preserving, we can first dry fresh chestnuts in a relatively ventilated environment. After two days, find a transparent and breathable cloth bag, put chestnuts in the bag, and then put the cloth bag in a cool place to achieve the function of storage. The storage time can reach about four or five months.

3, sand and gravel mixed preservation

This method is similar to mixed storage of sand and gravel. First, the sawdust and fresh chestnuts need to be mixed together and put into a suitable container. Spread a layer of sawdust on it without sealing, and then put it in a cool, ventilated and dark place. This method of storing chestnuts can extend the storage time of chestnuts to about two months.
