It generally takes more than 20 hours to dry mangoes with a professional mango heat pump dryer. Mango drying needs to set the drying time and drying humidity by partition. The specific temperature and humidity settings for mango drying are as follows:

The temperature of the first zone is set to 70 °C, the humidity is adjusted to 60%, and the time is about 6 hours. This time is the color fixing stage of the mango, in order to have sufficient heating and a large amount of moisture removal effect;

The temperature of the second zone is controlled at 60°C, the humidity can be adjusted to 40%, and the time is 12h. At this time, the mangoes have already been fixed, and the temperature does not need to be so high, but the humidity is still relatively high, and a large amount of moisture should be removed;

The temperature of the three zones is set to 50°C, the humidity can be adjusted to 30%, and the time is 8 hours. Because mangoes must maintain a certain humidity at the end, and the taste must be soft, so the temperature should not be too high in the later stage, and the humidity in the drying room at this time is also It is not too heavy, and it needs to be dehumidified slowly to ensure that the mango does not crack, the quality is good, the color is beautiful, and the hand is not sticky.

After the mango is dried, the moisture content is generally about 15%-18%. The product can be placed in an airtight container and allowed to soften for 2-3 hours, so that the moisture content of each part is balanced and the texture is soft, which is convenient for packaging and eating.
