How are dates dried?
Air-drying method: \x0d\ Spread the fresh jujube in a cool, dry and ventilated place, and turn it 1 time every 1 ~ 3 days, so that the jujube gradually loses water and becomes dried jujube. This method is suitable for rainy areas and varieties with thin pulp and coarse texture during harvest. The jujube made by this method has bright color, full appearance, few and shallow wrinkles and beautiful appearance. \x0d\x0d\ Sun-drying method: \ x0d \ Set a threshing floor in a dry, flat and ventilated place, and spread sorghum stalks on the brick floor, about 20cm from the ground, as a jujube shop. Spread jujube in the shape of high and low tiles, spread it evenly on the jujube shop and expose it to the sun, with a thickness of 6 ~ 10 cm, spread it 30 ~ 50 kg per square meter, turn it every 1 hour/time, and dry it evenly up and down. Gather in the middle of the shop at night and cover it with a mat to prevent the rain. If the weather is fine, it can be dried in 10 days. \x0d\ x0d \ Baking method: \ x0d \ Generally, a special curing barn with coal as raw material should be built. Various forms of curing barn are composed of heating system, ventilation and dehumidification system and loading system. \x0d\\x0d\ Baking method: \x0d\ Classify fresh dates according to their size and maturity, sort out rotten dates, and put them on trays and shelves respectively, with a suitable thickness of two layers. After the tray is put on the shelf, close the door and exhaust pipe and start baking. The whole baking process is divided into three stages: heating, evaporating water and drying. In the heating stage, the temperature of the curing barn should be slowly and steadily raised to 55℃; In the evaporation stage, the temperature is increased from 55℃ to 65 ~ 68℃, but it should not exceed 70℃ and kept for 8 ~ 65 00 hours; In the drying stage, the temperature of the curing barn is reduced to 55℃ for 4-6 hours. The tidal discharge in the whole stage is 1 ~ 2 times. In the future, pay attention to selecting jujube trays that meet the drying requirements and leave home at any time. \x0d\x0d\ Dryer Drying method: \ x0d \ This is a kind of high-efficiency drying equipment, commonly used are tunnel dryer, drum dryer and belt drier.
