The moisture migration of wood mainly contains two aspects: surface water evaporation and internal moisture migrates from the inner to the surface. Three factors will be considered in the conventional drying, they are air temperature, air humidity and circulation velocity. The ambient air pressure is one of the most important factors that may greatly affect the moisture migration speed in wood. The migration speed increased as air pressed decreased when other factors keep the same. Therefore, the vacuum drying has good quick drying effect.
Technical features :
-
Provide drying technologies that match different wood species according to customer requirements.
-
It is applicable to different kinds of woods, has good drying effect on softwood and broad leaf wood. Regarding wood easily cracked and collapsed, especially for the precious wood, this series dryer could obviously shorten drying time and improve drying result. So it becomes the first selected dryer for small wood processing factory.
-
This series dryer has features of high efficiency and energy saving, low drying cost. The drying speed has increased by 4 to 9 times compared with normal dryer, and the comprehensive energy consumption has decreased by 50%. It has advantages of good drying quality, good uniformity of moisture content, no deformation and no color difference.
-
It is safe and reliable, easy to operate. It is equipped with high quality control components, and several different detection points had been set for monitoring moisture content, medium temperature and vacuum degree.
-
There are 2 systems for selection, one is conventional process control and the other one is Microcomputer control system.
-
Steel structure, beautiful and compact, convenient for transportation and small occupation area.
-
It has reasonable internal structure, adopted total aluminum fan blades cable of positive and negative rotation with the advantages of uniform airflow and low resistance.The internal parts are made of stainless material, the inner surface of dryer has been treated with anticorrosion method.
-
The radiator is produced by using steel-aluminum composite material, which is less prone to corrosion. So this kind of radiator has relatively high coefficient of heat transfer and longer service life.
-
It has light weight, good effect of heat insulation, less heat loss.
-
It is equipped with two stage vacuum pump, extract air stage by stage with uniform pumping rate.
-
The dryer will be designed, manufactured, accepted and installed according to ISO9001.
-
Our company can also supply relative wood burning boiler and waste wood burning boiler to match GS series wood vacuum dryer.
