Stacking of wood drying kilnxingnan
In the process of wood drying kiln stacking, the same kiln dried lumber should plant species and initial moisture content is almost the same, the same thickness and generally does not allow mixed.
In the process of wood drying kiln stacking, wood lies between bar generally according to the thickness of the wood drying, section size between 3-5 cm width, thickness between 4-6 cm, specification should be consistent, the length is equal to the wood pile width.At straight texture, no knots, impact toughness and strength of skin defects such as good tree species, such as Korean pine, spruce, manchurian ash, meranti dried wood.Crosser spacing: soft wood pile, generally for the thickness of 18 to 20 times, broadleaf timber pile is generally 10 to 12 times the thickness, according to the thickness of dried lumber flexible control.Every article should be aligned, up and down in a vertical line, can’t stagger, otherwise the sawn timber easy to bending deformation.
In the process of wood drying kiln stacking, the longitudinal direction of the sawn timber and perpendicular to the direction of airflow crosser and air flow in the same direction, so that the material circulation flow smoothly through the pile of the horizontal airway.
In the process of wood drying kiln stacking, wood pile end of every article should clamp board, wood pile and the end of the wood pile close as far as possible, and as far as possible with the chamber wall alignment, in order to avoid end dry too fast, cause the crack.
In the process of wood drying kiln stacking, sawn timber should be single tile, close to each other, not double stacked together, pile material must be put into a regular hexahedron, not bad not oblique, if the length of the wood is not consistent, left the gap in pile as far as possible, keep the end flush.
In the process of wood drying kiln stacking, wood piles installed, necessary article at the top of the heap along every place heavy pressure, to prevent or mitigate lumber deformation, available section of 100 x 100 mm special reinforced concrete layering or waste wood pressure at the top.
In the process of wood drying kiln stacking, in a pile on both sides of the wood (not end side) should be about 50 cm distance from the wall of the vertical airway.
