    • A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure.Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets.
    • 用于干燥绿色薄板或部分干燥的单板的加热金属板干燥系统可以具有安装在框架上的多个模块化热压机。 在装载站处,将要干燥或重新干燥的各个薄板单元送入热压机中,并且在卸载站处,干燥的单板从系统中卸载。 在每个单独的模块化热压机中,发生直接接触干燥过程,其功能是将单板的水分含量降低到所需的均匀水平,例如在1至10%的范围内。 干燥过程接受不同种类,厚度和起始含水量的胶合板,受控过程变量包括接触时间,温度和压力。 每个单独的模块化印刷机可以是多开的,并具有打开和关闭命令的能力。 特别设计的加热金属板是每个压机的一部分,每个板在至少一个表面上具有基本平行的凹槽。 模块式压力机安装在框架上,使得它们可以在卸载站处倾斜以便于干燥的单板的卸载。
