With the use of a flash dryer, moisture can be reduced from 35% to 10%, making it suitable for briquetting. Heat is produced by the furnace to help dry the material. Raw materials are moved into pneumatic convey lines by screw conveyors in the presence of hot air. A cyclone collects dried material.

It is used to suspend-dry materials that are powdered, pulverized, or granular, such as sawdust, coir pith, and bagasse pith, which typically have moisture contents of 35% or below.
