Effects. platen temperature. moisture state. Poplar Lumber during hot-press drying
Abstract
[Objective]. Order. provide basis. analyzing hot-press drying mechanism. Temperature, pressure. Poplar Lumber(Populus tomentosa). Monitored during hot-press drying, Effects. platen temperature. temperaturePressure and momentum state in the core layer of Poplar lumber were further investigated.[Method]Temperature and Pressure in the core layer of Poplar lumber were measured with the integrated probe and real-time recorded with a data logger at the same time in Hot-press Drying,And the effects of platform temperature on momentum state were further analyzed in accordance with the comparison of measured pressure and saturated pressure(Theoretical pressure)Of vapor calculated with measured temperature in Poplar Lumber.[REsult]With the increase of Platform
