ABSTRACT:
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. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings. The loading apparatus is pivotally mounted. Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded. The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.
