For raw materials with heavy moisture content that above 12%, you need to install a drier, this drier reduces the moisture content below 12% before feeding them into Biomass / Charcoal Briquetting Screw Press.
Material for hot air stove: wood waste, wood briquette, coal, etc.
Principle:
In the dryer, high-speed hot air stream sustain raw material in the suspending state, then the material is dried. Since air stream speed is very high, and material is suspending in air stream, the heat transfer surface between air and solid is large, heat transfer rate is high. It¡¯s peculiarly suitable for drying heat sensitive material like sawdust, rice shell, milled stalks etc.
In drying process, clean cool air is heated by hot air stove, and mixed with wet material sent by spiral feeder. Wet sawdust is dried in few minutes. Dried material is discharged through centrifugal fan. Exhaust air is let out into atmosphere.
