séchoir à rouleaux

OBS: These driers may run up to 100 ft. in length and ... may consist of two to six decks ... Methods of propulsion through the driers vary considerably: generally veneer is held flat between mesh belts or bottom rollers with idle rollers above. Steam piping carefully positioned supplies the requisite heat. The drier may be ventilated along, or at right angles to, the direction of travel, the hot air being diffused against the passing veneer. The heating chamber is enclosed in a heavily insulated framework which prevents loss of heat by diffusion or radiation.
