Drying kiln use steps (2) the kiln stacking should pay attention to matters
Before the drying kiln is used, a comprehensive and detailed inspection of its shell and equipment must be carried out to ensure the normal operation of the drying process. The specific inspection contents are as follows:
Second, the kiln stacking should pay attention to matters.
Stacking is a simple and arduous work in wood drying production, and is an important part of the drying process. The specific matters that should be paid attention to are:
1. Selection of spacers: use 25mm*25mm spacers for plates with a thickness of less than 40mm, and 35mm*35mm spacers for plates with a thickness of more than 50mm.
2. The spacing of the spacers: the spacing of the hardwood spacers is 15-18 times the thickness of the board, and the spacing of the coniferous spacers is 20-22 times the thickness of the board. For boards with strict quality requirements, appropriate Reduce the spacer spacing.
3. When arranging the board, the spacer should be kept flush with the two ends of the board, and the upper and lower spacers should be kept vertical to prevent the moisture at the end of the board from being lost too quickly and uneven shrinkage leading to end cracks. The upper and lower spacers are kept vertical to prevent the plate from being balanced by gravity and to prevent warping.
4. For plates of different thicknesses, try to keep the same layer as the same thickness plate when arranging the plates, so as to avoid the drying deformation of the thinner plates caused by the plates of different thicknesses at the same layer, and at the same time ensure the stability of the stacking.
