Wood drying refers to the continuous removal of moisture from wood using appropriate drying techniques and equipment, including free water, inhaled water and mixed water, on the premise of ensuring the quality of wood.
1. Free water is present in the wood capillary system (this water is easily removed during wood drying and has the highest content）
2. Wood micro capillary adsorption of water, need a certain amount of energy and overcome the combination of micro capillary ability, water can be discharged from the wood is difficult to remove this moisture.
3. Chemical water is present in the chemical composition of wood and is about 1%. It cannot be removed by drying
As the wood dries, water can be removed from both ends of the board along the fiber direction, and from the surface and sides of the board along the fiber direction. Liquid water moves, steam or the mixture of steam and water is the main method.
Such as hot pressing veneer dryer, roller dryer or mesh belt dryer.
Roller dryer is composed of automatic feeding, heating chamber, cooling chamber and out-feeding, and can be matched with moisture and grade detector.
This model is straight-through horizontal circulation dryer. Its thermal circulation design draws on the technical advantages of advanced Dryer in Europe. It adopts vertical centrifugal fan with volute (flow rate up to 6.8
More than 10,000 ㎡/h).
Veneer warms up rapidly.Warm veneer dries up quickly and thoroughly. So veneer surface retains some moisture and does not crack.
Radial Fan:Circulation air blower and uniform flow rate.
Streamline airflow through tubes
High efficiency and energy savings
Round tubes creates high air turbulence, pressure loss and low heat transfer efficiency
Jumbo Radiators to maximize effective heating area
Radiator specific control valves for accurate
temperature control
Good corrosion protection through hot-dipped
