Although fresh chestnuts are nuts, they are also called "fresh fruits" in nuts. Because of their rich nutrition and high water content, they have strong vitality. They have four fears when they are stored: fear of freezing, heat, dryness, and water. Such as improper storage can easily cause dehydration, germination and decay. Generally, during storage, when the temperature in the sack exceeds 20 ° C, cooling measures such as inversion and bagging ventilation should be taken immediately.
There are two common chestnut storage methods:
(1) Sand hiding method: The temporary storage method commonly used in chestnut production areas is simple and easy to implement. After the chestnuts are temporarily collected, they are immediately wet with sand (the ratio of chestnut and sand is 1: 2), stirred and stored in a mat shed, buried, commonly known as "false burial" (sand hiding). Care should be taken when sand is stored: Generally, the humidity of the sand used for mixing should be held by hands and loosened.
(2) Refrigeration method: It is an important storage method for Chinese chestnuts for export. The general requirements for refrigerating conditions are that the temperature of the storehouse should be kept at 0 to 5 ° C with minimal fluctuations. The relative humidity should be above 80%. .
The chestnut stacking should be strictly managed in batches. The ventilation stack should be well stacked. The stacking distance should be more than 1m to facilitate the sampling and maintain air circulation.
