<p>The system dries items of organic material such as wood, e.g. veneer sheets, by circulating hot air using a fan and heat exchanger in a drying chamber. The moisture extracted is discharged by fan via a throttle flap to atmosphere. Temperature in the drying chamber is measured, and the shutter is used to regulate the quantity of outflowing air, so as to maintain a predetermined depression in the chamber. It can also be used to maintain a moisture content of the air of between 250 and 400 g of water per kg.</p> |
