China's export chestnut important storage methods, general refrigeration conditions require that the library temperature to maintain 0 ~ 5 ℃, as little as possible fluctuations in relative humidity should be more than 80%, the library carbon dioxide concentration is generally not higher than 3%.

Chestnuts are nuts, but also known as nuts in the "fresh fruit", due to nutrient-rich, high water, so the life activity is strong, keep up with four fear: fear of freezing, fear of heat, fear of dry and fear of water. Such as improper storage is very easy to cause water loss, germination and spoilage. Generally in the custody process, when the temperature in the sack exceeds 20 ℃, should immediately take the inverted stack, string bag ventilation and other cooling measures.

Sand storage method: chestnut producing areas commonly used temporary preservation methods, simple and easy to implement. Chestnut picking temporary concentration, immediately with wet sand (chestnut, sand ratio of 1:2), after mixing stored in the mat shed, buried, commonly known as "fake buried" (sand). Sand should be noted: the humidity of the sand mixing should generally be held in the hand into a ball, loose hand dispersal is appropriate.
