The second stage: the temperature is gradually increased to evaporate the water, the humidity should be adjusted to realize automatic dehumidification. Afterwards, the water vapor is discharged. This stage shall last for 2-3 days, so that most of the water is discharged.
The third stage: cool down to 55℃-60℃, and continue to dry for 2 days, so that the weight of the fruit drops to 25-30% of the fresh fruit, which means it becomes the dried fruit. Turn off the air energy drying & dehumidification heat pump system to let the fruit cool down naturally, and take it out after cooling.
