A sawdust air flow dryer is a drying equipment used to dry wood sawdust, rice husk, crushed wood shavings, branches, wood chips and other biomass materials (diamater < 3mm, length < 5mm). It is widely used in the biomass energy industry, wood processing plants, and other industries that require drying of biomass materials.
Structure: This air flow dryer is composed of a fan, a heating source, a drying pipe, and a cyclone separator. The sawdust or wood chips are fed into the drying pipe, where they are exposed to the hot air. The moisture evaporates and is carried away by air, while the dry material is discharged from the other end of the pipe. The cyclone separator is used to separate the dry material from the air and collect the dust.
The dried sawdust can then be used for various purposes, such as fuel, animal bedding, or as a raw material for the production of biomass briquettes, particleboard and other wood-based products.
