METHOD OF DRYING WOODEN BIOMASS RAW MATERIAL, AND DRYING FACILITY OF WOODEN BIOMASS RAW MATERIAL FOR USE THEREFOR

摘要

To provide a drying method capable of drying a wooden biomass raw material using a facility, fuel and the like corresponding to a drying throughput at all times, by eliminating the influence of an air temperature change, and a drying facility that can be used therefor.SOLUTION: A wooden biomass raw material containing moisture is dried by warm air of a temperature at a boiling point of water or lower, obtained by using a drying facility comprising a first heat exchanger 5 that preheats introduced air 3 introduced from the atmosphere, by exchanging heat between the introduced air 3 and water 4 for preheating having a temperature higher than an outdoor temperature, and a second heat exchanger 9 that carries out primary heating of air by exchanging heat between preheated air 6 and a heat medium 7 having absorbed heat from a high temperature heat source.SELECTED DRAWING: Figure 1
