Populus deltoides lumber were dried using high temperature dehumidification and conventional methods under the same schedule.Energy consumption and drying quality during the two drying methods were monitored and compared.Results showed that the energy consumption was different during various drying stages.It was found that the most effective way to save energy was in the initial period and it could save up to 30.5%.The high-temperature dehumidification drying consumed 34.1% less energy than the conventional drying without compromising the drying quality.It was expected that high-temperature dehumidification would increase its popularity along with the conventional drying in the future.
