Abstract
The invention belongs to a kind of rapid-result drying process of full wet panel of fast-growing eucalyptus and drying shed is applied, be related to wood processing field, specifically, belong to a kind of Wood drying technique and equipment.It is an object of the invention to provide a kind of rapid-result drying process of full wet panel of fast-growing eucalyptus and drying shed is applied, in order to realize that the technique in the task, the present invention is：Drying process step one：Saw plate, it is sawed-off into several sections by length-specific just to cut down fast-growing eucalyptus less than seven days, then is sawn into the sheet material of specific thicknesses；Drying process step 2：Sawed complete wet fast-growing eucalyptus sheet material is sent into special drying shed to be dried, the temperature and humidity in drying shed is respectively：First stage：Temperature is between 70-90 degree, and humidity duration 2-3 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving 95% or so；There is the present invention Guangxi fast-growing eucalyptus to be applicable, and dry the advantage of short time limit.
Description
Technical field
The present invention relates to wood processing field, specifically, belong to a kind of Wood drying technique and equipment.
Background technology
The fast-growing eucalyptus aboundresources in Guangxi, processes the manufacturer of fast-growing eucalyptus in Guangxi, also fairly common especially in Nanning City.
The drying of wood room of existing various models is all generally applicable type, is substantially what the north was developed, is relatively adapted to the timber in the north, and its drying process is relatively applicable the timber in the north, or adapts to a variety of different timber simultaneously.
The special drying process of sheet material specifically designed for the south particularly fast-growing eucalyptus in Guangxi is not found, in order to more targetedly dry the fast-growing eucalyptus of Guangxi production, special drying process and special equipment is especially released.
The content of the invention
It is an object of the invention to provide a kind of rapid-result drying process of full wet panel of fast-growing eucalyptus and drying shed is applied, in order to realize the task, scheme of the present invention is illustrated as；
First, overall technological scheme
1st, the invention belongs to a kind of rapid-result drying process of the full wet panel of fast-growing eucalyptus, it is characterized in that：
Drying process step one：Saw plate, it is sawed-off into several sections by length-specific just to cut down fast-growing eucalyptus less than seven days, then is sawn into the sheet material of specific thicknesses；
Drying process step 2：Sawed complete wet fast-growing eucalyptus sheet material is sent into special drying shed to be dried, the temperature and humidity in drying shed is respectively：
First stage：Temperature is between 70-90 degree, and humidity duration 2-3 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving 95% or so；
Second stage：Temperature is reduced between 50-60 degree, and humidity is reduced to 85% or so, duration 3-4 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving；
Phase III：Temperature is reduced to 30 degree or so, and humidity is reduced to 75% or so, duration 3-4 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving；
Drying process step 3：Repeatedly in the three phases in step 2, and Timing measurement drying shed the fast-growing eucalyptus sheet material moisture content, when moisture content be less than 30% when dry finish.
2nd, a kind of application apparatus implemented described in claim 1, including lumber kiln, it is characterized in that：
Also include a microwave dryer.
From the above it can be seen that there is the present invention Guangxi fast-growing eucalyptus to be applicable, the advantage of short time limit is dried.
Embodiment
The invention discloses one embodiment, it is described below：
1st, the invention belongs to a kind of rapid-result drying process of the full wet panel of fast-growing eucalyptus, it is characterized in that：
Drying process step one：Saw plate, it is sawed-off into several sections by length-specific just to cut down fast-growing eucalyptus less than seven days, then is sawn into the sheet material of specific thicknesses；
Drying process step 2：Sawed complete wet fast-growing eucalyptus sheet material is sent into special drying shed to be dried, the temperature and humidity in drying shed is respectively：
First stage：Temperature is between 70-90 degree, and humidity duration 2-3 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving 95% or so；
Second stage：Temperature is reduced between 50-60 degree, and humidity is reduced to 85% or so, duration 3-4 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving；
Phase III：Temperature is reduced to 30 degree or so, and humidity is reduced to 75% or so, duration 3-4 hour, the wind speed of the ventilation in drying shed is controlled in the premise of heat and moisture preserving；
Drying process step 3：Repeatedly in the three phases in step 2, and Timing measurement drying shed the fast-growing eucalyptus sheet material moisture content, when moisture content be less than 30% when dry finish.
In order to carry out specially treated for some specific sheet material positions, the present embodiment also includes a microwave dryer.
