After the irradiation is turned on, the temperature rises rapidly to above 50 °C within 10 min. Due to the existence of the sampling interval, the temperature of the air in the drying chamber decreases slightly because of the heat exchange between the air inside and outside the drying chamber, but the temperature tends to be stable on the whole.

In wood cm (1 inch) thick, moisture is reduced from 20 to 6 percent in 215 days and from green condition to 6 percent in 250 days. The source of heat is usually steam circulating in pipe coils. Relative humidity is controlled by allowing steam to enter the chamber through a perforated pipe; such control regulates the exit of moisture ...

Similar to dry air purges, dry nitrogen purges pull moisture out of the air within a test chamber, but, instead of using a desiccant humidifier, rely on ultradry nitrogen (which has a dew point of 70 degrees Celsius). When injected into an enclosed workspace, nitrogen expands and adds pressure, forcing the remaining moisture out of the chamber.
