Dry the fresh chipped material by a short time of fermentation
To get good results in drying the chipped material
, it is imperative to follow a procedure in wood harvesting.
It is very important to chip as sonn as possible after cutting. The best is to be able of cutting and chip in the same time.
It avoids tangle of branches, which would give a lot of difficulties during chipping.
By chipping as we cut, the workspace is well cleared, allowing an easier job and increasing safety.
In these contitions, fermentations starts quickly and strongly.
It is better to provide a storage on a height of 1 meter, during 1 month.
Fermentations increases the temperature, which will rise quickly 70 to 80 °C. If the heap is too big (too high), internal carbonization can occur an there will be loss of material.
After the first month of fermenting, the temperature falls and then it is possible to stock the chipper material in higher heaps.
The slower fermentation will continue to dry the chips, which will reach dryness less than 20% humidity on about three to five months.
