Procedure for drying an organic, most appropriately a xylogenic material, such as veneers for instance

Abstract From the Canadian patent

A procedure for drying organic materials including, xylogenic materials originating from wood such as veneers, by means of hot circulating air which circulates in a drying chamber from a blower to a heat exchanger passing by the, organic material, collecting the water vapour released therefrom, and continuing to the blower, whereafter part of the air/water vapour mixture is conducted through a vent throttled, by means of a damper, into the free atmosphere. In the drying chamber the temperature and pressure are monitored and the damper is used to control the quantity of the vented air so that there is a continuous predetermined vacuum in the drying chamber.
