This is a very interesting questions when we are trying to get better turnover and healthier cash flow in the wood drying field.
What we need make clear firstly is that the wood drying is an indispensable process in the usage of wood sources, when you get the raw materials from the forest, the water content in these wood are as high as 60% or even 100% more, they are easy to deformation and prone to pests and fungi, And the cost to transport these wood will be much higher than the dried one because the transportation is priced by weight.
And Then comes the question of how to dry the wood? There are many existing ways, like air drying, kiln drying , vacuum drying, high frequency drying etc., they are all of different features and are applicable for different cases, different people will choose different methods for their purposes, but one thing that is always a big concern and easy to compare is the drying speed, just like the other products, the best production mechanism is that you could get the finish product quickly, sell it and get back the investment & interests.
What is the fastest way to dry wood? And how fast is it?
As of the nowadays technology, the high frequency drying or Microwave Drying is the fastest way to dry the wood,the working process will be like that High frequency generator generates electromagnetic fields between two electrodes through three phase alternating current where the wood are loaded, In this field, water molecules are polarized – rotated – heated by friction. The heated water then will be vaporized and comes out of the wood.
It is totally different from the traditional kilns, for which you need first heat the air or the metal plates and then conduct the heat to the wood, it is a direct heating methods which works on the water inside the wood.
Such heating method will greatly shorten the drying process, and it will only take 3-10 days to dry the green wood to wood with below 10% water content. When we are talking higher temperature and higher airspeed in the traditional kilns to faster the drying speed, this kind of high frequency drying already totally redefine the drying fast to days, which may takes weeks before.
Anyway, there maybe different need of wood drying, like for furniture and fences , the MC results needed are different, for woodwoking and firewood, the quality requirement are not the same, but in every aspect and work conditions, High frequency drying are the fastest wood drying methods, It’s an innate advantage.
