3-6-1　木質チップの乾燥特性

抄録

A drying test was performed by sending warm air at 70 ° C. from the bottom at 0.13 m / s with wood cutting chips deposited. Temperature and humidity were measured at every 0.1 m of deposition height, and it was found that wood chips dried in order from the bottom side. In the early stages of drying, the drying speed is high because the supersaturated exhaust air is discharged. The drying time can be shortened by turning the wood chips upside down once during drying.
