A rotary drum dryer was shipped to Madagascar in July 2024. It’s specially tailored for the dehydration of wood chips, sawdust, and shavings. Moisture control is very critical to the further briquetting process. The raw material moisture is 25-30%, and it needs to be dried to 12-14% which is the optimal moisture content for further briquetting.
 
Actually the client installed a dryer at the early stage of the wood briquette project in Madagascar. But the actual yield was well below demand. After thorough research and evaluation, the customer chose SIMEC technology to replace the existing dryer. To fulfill the project demand, SIMEC developed a streamlined single-pass rotary drying system that comprises a feeding silo for raw material introduction, a feed conveyor for ensuring smooth feeding, a hot air stove for the generation of clean hot air stream, a rotary drum where the dehydration occurs, an output conveyor for the efficient discharge of dried material, a cyclone system for dust recovery and wet scrubber for emission purification. The design capacity is 1 ton/hour of dried wood sawdust.
