Method for drying coarse chips (hogged wood) of softwood, in particular of pinewood

摘要

The object of the invention is to carry out a natural drying process of the coarse chips by achieving a large difference between the water-vapour partial pressure at the surface of the wood and in the surrounding air. This is achieved in that, according to the invention, the coarse chips are dynamically stored and dried, in the state at the time of supply, in a continuous- and buffer-type arrangement which is deposited as a loose heap forming natural drainage systems and has a firm foundation, and the continuous- and buffer-type arrangement is operated in a manner limited in time as a function of the composition of the coarse chips, the water content, the outside temperatures and the amounts of precipitation. <IMAGE>
