Cold Storage with chestnut chestnut is the best way, using cold storage of chestnut decay and less wear and tear, almost no germination phenomenon, can better maintain its original quality taste, storage of up to 1 year. Chestnut refrigerated cold storage is at a certain low temperature storage, now use more storage cold storage, cold storage cold storage for short, basically consists of holding two parts warehouse and refrigeration equipment. Treasury is assembled with insulation made of insulating material, refrigeration equipment, including refrigeration units, chillers and microcomputer temperature control system. Chestnut small refrigerator design and construction of structures to be professional refrigeration design, small single room of about 10 square meters, more than 50 square meters large to pass between can be. Insulation with polyurethane insulation library board, library board, easy accessibility, to meet the needs of chestnut cold storage insulation. Chestnut refrigerated cold storage design temperature of -2 ℃ ~ -1 ℃, suitable relative humidity of about 95%. Freshly picked chestnut should quickly reduce the temperature, usually with a string bag (ie, pour another bag from a bag) method to cool faster. Stacking methods: the first pad on the ground floor sleepers, one sack and one sleeper, so separated between the upper and lower sack for ventilation to prevent heat within the package. Stacking height of 3 to 6 bags appropriate. Humidification method: hang wet straw mat or ground sprinkler, the amount of water can be sprayed directly on the sacks. Chestnut Chestnut cold storage, the first to do the preparatory work before the Treasury reservoir. Mainly Treasury disinfection and pre-cooling. Before entering the reservoir 10 to 15 days with smoked sulfur Treasury disinfection method, per square meter with 10 to 20 grams of sulfur, sealed 24 hours after ignition. The new library without disinfection, but fruit boxes and other packing materials should be disinfected and sprayed fungicide carbendazim 500 times. Then the Treasury pre-cooling, which turned into a storage refrigerator before 7 to 10 days, start 6 to 8 hours a day, three to five days to make the cold temperature stabilized at about 0 ℃. But be sure to note that you must 3 to 5 days for the entire refrigeration equipment repair before turning to ensure the normal operation of the unit. Treasury ready, then the heat through sweating, sterilization, insecticide and other pretreatment chestnut packaging and warehousing storage. Chestnut refrigerated packaging commonly used outer and inner layers of packaging, the packaging with non-toxic PVC plastic, about 0.03 mm thick bags, packaging specifications according to the size of the container may be. Generally there is a large bag, pouch two kinds. Big bags of 70 cm × 90 cm, 20 to 25 kg loading fruit, pouch for 60 cm × 70 cm, 15 kg loading fruit. To advance with a big bag on the number of punches holes, to facilitate through wet gas. General packaging cartons or wooden boxes, rear chestnut packing, stacking storage to storage. Fruit boxes stacked in the library is not too high, and the wall between the crib, set aside between the stacks and stacks and boxes certain gap, to facilitate ventilation and cooling. Chestnut should be strictly controlled storage stages. After each batch of cool storage to timely, when the first batch of fruit storage temperature requirements are not reduced, the next batch of re-entry can not otherwise easily lead to difficult or prolonged cold cool down less than the required temperature, Chestnut refrigeration effect. After the main storage management is to adjust the temperature control within the library, humidity and gas composition. Among them, the most important of temperature management. Usually after all the fruit storage warehouse, should be reduced to around 0 ℃ in 7 days after making the storage temperature is maintained at between -1 ~ 1 ℃. Chestnut Storage temperature should be controlled at about 0 ℃, the lower limit of the fluctuation between ± 1 ℃ more appropriate. Recommended small refrigerator, usually automatic temperature control, if the hand-control system, control the switching time of a good machine, so that the temperature does not fluctuate too much. Cold storage relative humidity should be controlled at 85% to 90%. Liguo using plastic bags, can reduce water loss fruit itself, usually without special humidification. However, if the library is too dry, can be spray humidification. Within chestnut cold fruit through respiration continuously emit carbon dioxide and other gases detrimental to fruit storage, such as ethylene. The accumulation of carbon dioxide in the library can cause high concentrations of fruit physiological disorders and quality deterioration. Therefore, timely ventilation. Ventilation should be selected at a lower temperature in the morning were, open doors, while starting to slow refrigerator temperature.
