◆ The capacity of the air (gas) stream to absorb and carry away moisture determines the drying rate and establishes the duration of the drying cycle.
◆ In recirculating ovens only a portion of the air is removed and replaced with each passing.
◆ Single pass ovens do not recirculate air and are as a result more efficient.
◆ Drying cycles are usually faster, especially with solvents.
◆ With the right combination of heating temperature and humidity setpoint it is possible to achieve a lower residual solvent level mush faster.
