ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a method for accelerating dehydration of wooden material.
BACKGROUND OF THE INVENTION
A conventional process of dehydration for wooden material such as logs or bamboo is to collect the logs or bamboo in a cool and dry area to let the moisture in the wooden material release naturally. This conventional method takes a long time and requires a large area for the wooden material. During the process of dehydration, damage due to insects or nature disasters could happen and results lost to the wood merchants. The long waiting period cannot meet needs of markets and the wooden products could deform if the dehydration process is not completely proceeded. As shown in
FIG. 1
, when the cambium is transferred to xylem, the conduits
111
and fibers
112
of the wood become the main passages for the moisture
13
to release from the wood. Nevertheless, there is gluey particles
12
located in the conduits
111
and the gluey particles
12
stock the conduits
111
so that moisture
13
cannot release. Therefore, the waiting period will be prolonged.
The present invention intends to provide a method that effectively shortens the period for dehydrating the wooden material.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a method for dehydrating wooden material and including step
1
to cut wooden material into sections; step
2
to soak the wooden material in oil and to heat the oil; step
3
to soak the wooden material in step
2
in boiling water to resolve the gluey material in the wooden material; step
4
to cool the wooden material in step
3
; step
5
to remove gluey particles on surface of the wooden material, and step
6
to dry the wooden material in step
5
.
The primary object of the present invention is to provide a method that shortens the period for dehydrating wooden material.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
