1. The production process of dried dragon fruit

Raw material selection→cleaning and slicing→color protection, hardening and blanching→deoxidizing throat smell→vacuum candy→drying and softening→packaging of dried fruit

2. Dragon fruit drying reference process

When baking, the two passages in the drying room should pay attention to the material balance, so that the dragon fruit slices are heated evenly. Set the temperature, humidity, and other parameters of the dragon fruit dryer and the drying mode. Generally, the best effect is to bake at 55℃-75℃ for 15-20 hours, until the moisture content of the dried fruit is about 10%-15%.

3. The specific drying process of dragon fruit can be completed in four stages:

• The first stage: the temperature is set at 60°C, the humidity is set at 35%, the mode is drying + dehumidification, and the baking time is 2 hours;
• In the second stage: the temperature is 65 °C, the humidity is set to 25%, the mode is selected to dry + dehumidification, and the baking is about 8 hours;
• In the third stage: the temperature is raised to 70°C, the humidity is set to 15%, the mode is drying + dehumidification, and the baking time is 8 hours;
