Embodiment 1
[0029] Poplar, initial moisture content is 120%, thickness 5.0cm, adopts the rapid drying method of poplar plank of the present invention to carry out drying treatment.
[0030] 1) Palletizing
[0031] Make poplar stacks with a length of 3.0m, a width of 1.6m, and a height of 1.4m. Close the gate.
[0032] 2) poplar wood pretreatment
[0033] The heated humid air is fed into the pretreatment kiln through the circulating fan, and the steam spraying treatment starts when the temperature of the incoming material stack reaches 60°C. The temperature of the superheated steam at normal pressure is between 150°C and 160°C. At 90°C, heat preservation starts, and the heat preservation time is 1.5 hours / cm, that is, 7.5 hours. After the treatment, the poplar is taken out of the kiln for drying. When leaving the kiln, the moisture content can be reduced to 60% to 80%.
[0034] 3) poplar wood drying
[0035] The treated poplar is correctly stacked in the drying kiln according to the ...
Embodiment 2
[0041] Poplar, initial moisture content is 140%, thickness 7.0cm, adopts the rapid drying method of poplar plank of the present invention to carry out drying treatment.
[0042] 1) Palletizing
[0043] Make poplar stacks with a length of 3.0m, a width of 1.8m, and a height of 1.6m. Close the gate.
[0044] 2) poplar wood pretreatment
[0045] The heated humid air is introduced into the pretreatment kiln through the circulating fan, and the steam spraying treatment starts when the temperature of the incoming material pile reaches 60°C, the temperature of the superheated steam at normal pressure is between 140°C and 150°C, when the temperature of the wood core reaches 60°C At 90°C, heat preservation starts, and the heat preservation time is 2 hours / cm, that is, 14 hours. After the treatment, the poplar is taken out of the kiln for drying. When leaving the kiln, the moisture content can be reduced to 70% to 80%.
[0046] 3) poplar wood drying
[0047] The treated poplar is ...
