3.What´s thepurposewe need wood drying machine?
Most of the waste of wood resources is due to the fact that wet
wood has not been dried or improperly treated, resulting in the
degradation of wood and even loss of use value.
The purpose of wood drying treatment is:
(1) to prevent the deformation and cracking of wood
(2) to improve the mechanical strength and physical properties of
(3) to prevent wood decay and moth
(4) to reduce the weight of wood
4. Present situation of wood drying technology
1)Wood drying industry has great potential for development.
The drying capacity of middle developed countries can reach 30% of
the required drying capacity, while that of the United States is as
high as 60%.
2) High energy consumption in drying and environmental pollution
Steam drying accounts for more than 80% of the existing wood drying
equipment. Furnace gas and direct-fired flue gas drying are more
common in small enterprises. Boiler is used as heating equipment in
steam drying. The average thermal efficiency of industrial boilers
and their pipe networks in China is only 60%. At the same time, the
heat loss of steam drying´s inlet and exhaust accounts for about
40% of the steam heat energy. In addition, there are heat loss of
wall gates and so on. Therefore, the primary energy utilization
rate of steam drying is generally less than 30%. The high energy
consumption of drying not only increases the cost of products, but
also increases the smoke and exhaust gas discharged from boilers
and drying chambers, thus increasing the pollution of these harmful
substances to the atmosphere.
3) Principle of Microwave Drying of Wood
Wood microwave drying is a new technology, which has the advantages
ofuniform heating, fast drying speed, non-deformity, good quality,
and is conducive to continuous and automated production.
Wood microwave drying is different from traditional wood drying
equipment, it is a frequency of 300 MHZ to 300 GMHZ, its
corresponding wavelength is MM to DM (10-10M) order of magnitude,
than light wave, infrared wave length, belongs to high-frequency
Microwave heating is carried out at the same time inside and
outside the material, which has the characteristics of instant
heating and no thermal inertia, so it is easy to control in the
drying process, and there is no noise and harmful gas emissions. It
belongs toenvironmental protection drying technology. Simply speaking, microwave is directly heated through the
moisture contained in the material and absorbed by the wood itself.
Because of the evaporation of moisture on the surface of the
material, the temperature inside the material is higher than that
on the surface. The pressure difference inside the material forms
outward, which accelerates the surface migration of water.
Therefore, the drying speed of wood by microwave is much faster
than that by convective drying by 20 - 30 times. Compared with far
infrared and steam drying,the energy consumption is reduced by more than 25%.
Microwave drying of materials can make the temperature inside wood
higher than 60degree.The parasitic eggs in materials can be quickly killed to prevent
borers and mildews. The best benefit can be obtained for all kinds
of wood conditions with different properties.
