What is the dehumidification working principle of veneer dryer?
The products can also be used as other tunnel wood drying equipment, especially suitable for wood with an initial moisture content of about 28% and a moisture content of 10-8%, which can dry the wood in a short period of time, and can also dry the wood crafts, decorations and special standard wood.
The dehumidification working principle of the veneer dryer is to use the unsaturated wet air to dry the wood to absorb the moisture in it, and at the same time, in order to improve the moisture absorption of the wet air, the moisture is heated first. Wood drying equipment uses heating equipment to heat wet air under constant pressure, so that the wet air is heated externally, and the temperature of the wet air rises. The water vapor component in the wet air is not increased, and there is no condensation of steam to precipitate, so that the relative humidity is reduced to a certain level, thereby improving the moisture absorption capacity. Obviously, the heating process in the heating equipment is a constant temperature enthalpy increase as a constant specific humidity process. When the heated wet air enters the dryer to dry the wood, it mainly uses the wet air to dissipate heat (the enthalpy of the wet air vaporizes the water in the wet substance into the air, raising the enthalpy of the water vapor contained in the air. On this basis, the drying dehumidification technology can be approximately regarded as a constant enthalpy process in which the air temperature gradually decreases and the humidity gradually increases.
