The drum dryer is the **key drying equipment** in wood chip charcoal production lines, used to reduce the moisture content of raw materials. Its primary function is to continuously lift and scatter wood chip particles—still containing high moisture after crusher processing—via the scraper blades inside the cylinder. This ensures thorough contact with high-temperature hot air, rapidly removing moisture to guarantee the final product’s moisture content remains uniformly stable within the 8%-12% range required for briquette production.

Featuring a large rotary drum structure, this equipment delivers high thermal efficiency, substantial processing capacity, and uniform drying results. By adjusting rotational speed and hot air temperature, it flexibly accommodates drying requirements for materials with varying moisture levels. As the intermediate link between crushing and briquetting, the stable operation of the drum dryer directly determines the quality and efficiency of subsequent briquette forming. It serves as the **core guarantee** for achieving continuous, large-scale operations in wood chip charcoal production lines.
