Abstract
A kind of drying means of artificial forest speed Feng An sawn timbers.It specifically includes：Sawn timber stacking, sawn timber gas are done, sawn timber spontaneously dries, sawn timber high-temperature pressurizing is dry, qualified sawn timber.By implementing the present invention, by the way that sawn timber is laid out stacking, sawn timber is done and spontaneously dried into promoting the circulation of qi by layout under suitable natural environment simultaneously, finally dried again by high-temperature pressurizing, so low energy consumption in the drying process for sawn timber, and pass through above-mentioned dried sawn timber flatness height and without cracking phenomena, effectively reduce drying cost, more effectively solve defect caused by traditional drying.Process is simple during present invention operation, and production cost is low, but acts on significantly, highly widelys popularize.
Description
Technical field
The invention belongs to a kind of drying means of timber, and in particular to a kind of drying side of artificial forest speed Feng An sawn timbers
Method.
Technical background
At present, the timber that China has been carried out turning to based on utilization wildwood timber based on utilization artificial forest wood provides
The fundamental shifts of source structure.
Guangxi fast-growing eucalyptus belongs to difficult seasoned wood, and speed Feng An dryings are global problems.Fast Feng An dryings of wood drying shrinkage
Rate is high, and diffusivity is low, easily the defects of the modification of generation surface warp cracking, shrinkage, implosion, interior empty (cellular cavity), uses
Traditional conventional kiln drying (kd) method is dried processing and is difficult to overcome problem above, results even in completely written-off situation and occurs.
The content of the invention
The purpose of the present invention is exactly to overcome the shortcomings of the prior art and provide a kind of brand-new artificial forest speed Feng An saws
The drying means of material.It specifically includes：Sawn timber stacking, sawn timber gas are done, sawn timber spontaneously dries, sawn timber high-temperature pressurizing is dry, qualified saw
Material.
The present invention is achieved through the following technical solutions：
A kind of drying means of artificial forest speed Feng An sawn timbers is to include the following steps in technical solution：
1st, stacking：Sawn timber is subjected to stacking by thickness, width dimensions respectively, with the parting bead of consistency of thickness between sawn timber during stacking
Separate, the distance between parting bead uniformly and more than 20cm, meanwhile, ensure parting bead be pressed on sawn timber length to both ends；
2nd, gas is done：When sawn timber moisture content is more than 40%, material pile is placed in the environment of no burning sun is exposed to the sun and is done into promoting the circulation of qi；
3rd, spontaneously dry：When sawn timber moisture content is down to 25%-30%, material pile is placed in the environment of sharp draft and is carried out certainly
It is so dry；
4th, high-temperature pressurizing is dried：When sawn timber moisture content is down to less than 18%, then sawn timber is laid in 90 to 130 DEG C of high temperature
High-pressure drying in hot plate, pressure are set in 1-3kg/cm according to sawn timber thickness2Between, between the time is when 0.5-2 is small；
5th, qualified sawn timber：Sawn timber passes through as qualified sawn timber when hot-pressing drying to moisture content is 6-8%.
The invention has the advantages that：
1st, drying means technology novelty, scientific and reasonable, the significant effect of speed Feng An sawn timbers proposed by the invention.
2nd, by applying the present invention, by the way that sawn timber is laid out stacking, while layout will under suitable natural environment
Sawn timber is done and is spontaneously dried into promoting the circulation of qi, is finally dried again by high-temperature pressurizing, so low energy consumption in the drying process for sawn timber, and passes through
It crosses above-mentioned dried sawn timber flatness height and without cracking phenomena, effectively reduces drying cost, more effectively solve
Defect caused by traditional drying.
3rd, process is simple during present invention operation, and production cost is low, but acts on significantly, highly widelys popularize.
