The traditional incense drying method is as follows: set up a shed through occupying large areas of land and put the incense on it for sun drying. If it is a cloudy or rainy day, the incense will go moldy so as to influence its color. the uncontrollable environmental condition have become a block for many incense producers. Therefore, the modern drying process should be brought in for incense mass production.
The heat pump drying process for your better reference:
1. The preliminary temperature should be controlled at 45℃, humidity at 60%RH and the drying time within 5-6 hours.
2. The temperature should be adjusted to 50℃ with 3 hours drying time in the middle period.
3. For the ending period, the temperature should be adjusted to 55℃ with unadjusted humidity.
Generally speaking, the whole incense drying process should be mainly controlled at low and medium temperature. As a result, the dried incense will have uniform color, full bodied and evocative smell.
