The main function of the wood single drum dryer machine is to dry the wet sawdust, and the hot air enters the wood single drum dryer machine to promote the moisture evaporation of the wet sawdust, and the evaporation of water vapor is taken away by the fan. When we configure the biomass pellet production line, the basis for configuring the wood single drum dryer machine is composed of the following points.

First: Through the moisture tester to test the moisture of the original wood sawdust, the production of biomass pellet requires that the moisture after drying is less than 15%. So we can calculate the amount of water vapor evaporation, we can configure the wood single drum dryer machine according to the amount of water vapor evaporation.
Second: Configure the wood single drum dryer machine according to the production of biomass pellets. For example: the yield is 2 tons of pellet per hour, the original moisture is 50%, and the moisture after drying is 15%. So his evaporation rate is 35%, and he evaporates 1.08 tons of water vapor per hour. We can configure the wood single drum dryer machine according to the steam evaporation rate of 1.08 tons per hour.
Third: According to the size of the material configuration of the wood single drum dryer machine, such as the size of the material 6-8mm, the evaporation speed of water vapor is relatively fast, the wood single drum dryer machine built-in guide plate design operating Angle is 45°, the material forward speed is relatively fast. For example, the size of the material is 1-3cm, the evaporation rate of water vapor is relatively slow, and the time needed to stay in the wood chip tumble dryer is relatively long, the built-in guide plate design operating Angle is 30°, and the forward speed of the material is relatively slow.
