In order to produce high quality wood pellets, the raw material must maintains a moisture content of 8% - 12%, so the raw material must be put into a dryer to reduce its moisture content. The most common dryer for large pellet plant is the rotary dryer, which is the most cost effective choice for large pellet plant.
