Put the fruit into the baking tray and send it to the sulfur fumigation room. Put the sulfur in a bowl, add wood chips to support combustion, close the door of the sulfur-fumigation chamber after lighting, and smoke it for about 1 hour. Generally, 2-3 kg of sulfur powder is used per ton of fruit.
2 Dry and soften
The 3P machine should be equipped in a drying room with about 15 cubic meters, the 6P machine should be equipped in a drying room with 25-30 meters, and the 12P machine should be equipped in a drying room with 40-45 meters. Spread the sulfurized cherries evenly on the baking tray and send them to the drying room for drying. At the beginning, the temperature is controlled at about 60°C, and continuous dehumidification is carried out. The air humidity is reduced to about 50%. When it becomes slighted dried, the temperature is raised to 75°C-80°C, and the air humidity is lowered to about 25%. After 8-12 hours, take it out, pick out the undried fruit, and put it on another baking tray to dry again. When the air humidity drops to 25%, the internal humidity content of the dried cherries should be 18%.
