Case of fermentation and drying wood chips for woody biomass power generation and for bedding production (Introduced to: Recycling facility for felled trees, pruned branches, etc.)
In this case, fermentation and drying technology was used to dry mostly raw wood and other woody matter with a high moisture content, such as felled trees, pruned branches, and wood mixed with weeds.
On the left is raw wood with a high moisture content, on the right is the wood after drying.
The heat of fermentation is used to evaporate moisture.
Drying is finished in just a few days.
It is basically not necessary to do turn over work while the wood is drying.
The distinguishing feature of this method is that takes only a fraction of the running cost of drying with fuel oil.
However, efficiency may decrease in regions with high humidity.
