S5：Timber kiln discharge：After the moisture content deviation between monitoring point in dry kiln is less than 5%, terminates whole drying process, treat wood
Material temperature is cooled to and is no more than kiln discharge after 15 DEG C higher than outdoor environment temperature, and dried timber is placed in into progress in siccative canopy
Health is handled.
In this method, temperature is unique control parameter, and kiln temperature is up to 120 DEG C -160 DEG C, and the water for steaming component 4 steams
Thermal expansion make it that air pressure is slightly larger than atmospheric pressure in kiln, can be discharged by gas deflation assembly 6, realize kiln after gas is heated by heating component 3
The function that interior humid air is automatically drained out；Vapor is full of in kiln, makes the presence for not having oxygen in kiln, the danger caught fire, exploded is excluded
The problem of danger and timber are oxidized discoloration；Dried medium overheat gasification vapor has thermal capacity high, the characteristics of coefficient of heat transfer is big,
Volume drying speed is substantially accelerated；Dried medium and the mass exchange of extraneous air, heat is not present in the heat supply system of closed cycle
Small, more conventional drying means is lost, its energy consumption for drying can reduce by more than 40%, and drying uniformity is good, and lacked without obvious dry
Fall into；There is no dust and volatile materials to be discharged into air in drying process, the advantage with environmental protection is a kind of efficiently excellent
Matter, low energy, drying of wood new technology simple to operate.
In the present embodiment, in step sl, stacking processing is carried out to timber according to LY/T1068-2012 standards, material heap is high
Spend for 2-3m, material heap width is 2-2.4m, parting bead cross dimensions thickness is 25mm, and parting bead cross dimensions width is 30mm.So
Set, be easy to timber batch is orderly to be dried.
It is 2.0m by length, width is natural width, and thickness is so that first moisture content is 82% wet Lumber of Pinus Massoniana as an example
25mm, first moisture content is 82% wet Lumber of Pinus Massoniana, and Lumber of Pinus Massoniana is carried out at stacking according to LY/T1068-2012 standards
Reason, material stack height 2m, material heap width 2m, parting bead cross dimensions 25mm（Thickness）×30mm（Width）, length is 2.4m, and by will
Seek the placement Temperature Humidity Sensor 7 in material heap.Material heap is sent in the drying of wood area 11 of kiln body 1 using bottom rail 14, kiln is closed
Door 12, opens axial flow blower 21, heating component 3 and steams component 4, timber is dried processing using progressively temperature-raising method, first
50 DEG C are warming up to 15 DEG C/h heating rate, 1h is incubated, makes the abundant heat penetration of timber, then be warming up to 20 DEG C/h heating rate
100 DEG C, it is incubated in 1.5h, temperature-rise period, the humidity in kiln is maintained at more than 95%, when humidity is reached after 95%, closes and steam
Component 4.After insulation terminates, continue temperature rising to 140 DEG C, heating rate is controlled in 10 DEG C/h, and in this case, timber is done
The dry moisture content that arrives is 6%.After high temperature section drying terminates, heating component 3 is closed, condensate water circulatory component 5 is opened, makes kiln temperature
85 DEG C are reduced to, condensate water circulatory component 5 is closed, is again turned on heating component 3, kiln temperature is maintained 85 DEG C, and in this temperature
Under to timber carry out high humidity Balance Treatment, 2.7h is kept in this case, heating component 3 is then shut off, treat Wood temperature cool down
Kiln discharge after 15 DEG C is no more than to higher than outdoor environment temperature, timber end moisture content is 2.6%；Finally dried timber is placed in
Health processing is carried out in siccative canopy.In this example, using the energy-efficient drying means of minute-pressure self arrangement timber with device to first
Processing is dried for 82% Masson pine timber in moisture content, and drying time is 24 hours, and rate of drying is fast, and dry mass reaches
With the external world without air exchange in two grades of Drying quality of sawn timber standards, drying process, internal pressure realizes water vapour self-discharging.
Embodiment of the method 2：
It is 1.0m by length, width is 180mm, and thickness is 22mm so that first moisture content is 57% keteleeria fortunei sawn timber as an example, it is just aqueous
Rate be 57% keteleeria fortunei sawn timber, according to LY/T1068-2012 standards to keteleeria fortunei sawn timber carry out stacking processing, material stack height 2.2m,
Material heap width 2.4m, parting bead cross dimensions 25mm（Thickness）×30mm（Width）, length is 2.5m, and is pacified on request in material heap
Put Temperature Humidity Sensor 7.Material heap is sent in the drying of wood area 11 of kiln body 1 using bottom rail 14, wicket 12 is closed, axle stream is opened
Blower fan 21, heating component 3 and steam-injection component 4, timber are dried processing, first with 15 DEG C/h heating using progressively temperature-raising method
Speed is warming up to 50 DEG C, is incubated 2h, makes the abundant heat penetration of timber, then is warming up to 100 DEG C with 20 DEG C/h heating rate, is incubated 2h.
In temperature-rise period, the humidity in kiln is maintained at more than 95%, when humidity is reached after 95%, closes and steams component 4.Insulation terminates
Afterwards, 150 DEG C are warming up to 8 DEG C/h heating rate, are 5% by the drying of wood to moisture content under this temperature conditions.High temperature is done
After the completion of dry section, heating component 3 is closed, condensate water circulatory component 5 is opened, kiln temperature is reduced to 88 DEG C, condensed water is closed
Recirculation assembly 5, is again turned on heating component 3, kiln temperature is maintained 88 DEG C, and carried out at this temperature to timber at high humidity balance
Reason, keeps 3.2h, is then shut off heating component 3, treat that Wood temperature is cooled to and do not surpass higher than outdoor environment temperature in this case
Kiln discharge after 15 DEG C is crossed, timber end moisture content is 2.3%；Dried timber is finally placed in progress health processing in siccative canopy.
In this example, the energy-efficient drying means of minute-pressure self arrangement timber is used to enter with device to first moisture content for 57% keteleeria fortunei timber
Row drying process, drying time is 19 hours, and rate of drying is fast, and dry mass reaches two grades of Drying quality of sawn timber standards, is dried
During with the external world without air exchange, internal pressure realizes water vapour self-discharging.
