1, the original barbed robe is preserved. Chestnuts have a protective shell covered with thorns. When chestnuts do not fall off the shell, they can be kept flat and not piled up, and can be stored for about 30 days.

2, ventilated and cool preservation method. Chestnut hulling itself is still undergoing various life reactions. Chestnut can be laid flat on the cement floor or bamboo products and stored in a dark and ventilated place for more than 30 days.

3. Sand storage method. Chestnuts can be stored for a long time in linen bags, covered with straw and covered with sand about 20 cm thick.

4. Cold storage method. Putting fresh chestnuts in the sun for a day or so, peeling chestnuts, putting them in fresh-keeping bags, tying their mouths and putting them in the refrigerator can also improve the fresh-keeping time. Note that chestnuts must be taken out and stored in the refrigerator, otherwise chestnuts are easy to get moldy.

5, crock storage method. Air-dry chestnuts for one day and then put them into a crock, where the crock is padded with 5cm thick dry straw, and chestnuts are put into 80% of the jar mouth at most, and the rest space is filled with dry straw. Put the cylinder on a dry wood or a hanging shelf. It can also be preserved for a long time.
