Fresh wood contains a lot of moisture which will continue evaporating in a certain environment. If the water evaporates naturally, wood will shrink, crack, bend, deform, and even ferment, which will damage the quality of wood products. Therefore, wood has to be dried on a controllable basis before being made into wood products. The correct drying process can overcome the defects mentioned above, and enhance its mechanical strength and processability. It is an important technology-based measure to make reasonable use of wood and to add its values and a e primary and necessary procedure to produce wood products. Energy consumption of drying wood accounts for 40-70% of the total of producing wood products. The drying process wastes heat too much with an energy consumption of 30%. The energy cost in the drying process occupies more than 50% of the total drying cost. As the imbalance between the supply and demand of energy is increasing and the environmental problem caused by the atmospheric greenhouse effect is more and more severe, the wooden industry pays greater attention to the energy-saving wood-drying process. In the past twenty years, many drying technologies have been developed. Among them, the heat pump drying process has posted a better performance in saving energy. KINKAI wood dryer has the capability of drying varieties of wood such as logs, rosewood, and cabinet wood, and really solves the problems customers are faced with in the drying process.
Factors influencing the wood drying
Wood temperature: Measure and control the dry-bulb temperature to adjust the working status of the heating system so as to control the
the temperature in the cabinet.
Wood humanity: Measure the difference between dry-bulb temperature and wet-bulb temperature to adjust the dehumidification amount
and the working status of the spraying system to automatically control the humanity in the cabinet.
The moisture content of wood: Adopt the resistance-based moisture meter to prevent limitation and deviation arising from measurement and to provide an effective technology-based guarantee for the accurate performance of the moisture content baseline for wood.
The wood drying equipment that wants to dry wood on a controllable basis must have three basic functions: heating, adjustment of
humanity, and ventilation.
The heating speaks for itself. Adjustment of humanity is used to provide the high-humanity environment necessary for some phases to prevent the wood from cracking and deforming. The ventilation device must ensure that the wet and hot air goes through the pile of wood evenly so as to make the water in the dried wood well-distributed.In the early drying process, the performance coefficient (COP) of the heat pump unit is high due to the high relative humanity of the wood to be dried. As the drying process goes on, the COP will decline due to a decrease in the relative humanity, resulting in lower performance of the unit on a negative basis.
If the temperature is not high, for example, the low-temperature heat pump is below 54 ° C, moisture can’t be removed from the wood in case the moisture content is below 15%. Generally, it is necessary to raise the drying temperature to 71°C or above. The drying cabinet shall be thermal insulation and resistant to air loss. In terms of thermal insulation, the cabinet structure shall have a small thermal capacity to reduce heat loss, which is equal to or less than the mechanical equivalent of heat. No humidifying equipment is installed in the heat pump drying cabinet. If the water vapor overflows, it is definite that the drying condition is hard to change.
Therefore, the cabinet shall have good air impermeability. Keep the airflow in the cabinet stable. It is best if the airspeed is 1m/s.
Use electric energy to supply power, absorb the air in the surrounding environment through heat pump technology, convert the air source into a heat source, convert 1 kWh of electric energy into 4 parts of air heat energy, save 75% of electricity, and play a high-efficiency, energy-saving, and environmentally friendly role.
