Timbers/Theory 3
Air drying-
Air drying is a simple method where the various types of timber are stacked on top of eachother but are separated by something called stickers, this allows the air to circulate around it speeding up the process. The process requires a place where it is clean, cool, and dry. The process can take months and even years depending on the climate, so therefore it is a very slow process.
Kiln drying-
Kiln drying is where the timber is basically introduced to heat, this can be directly using natural gas and/or electricity or indirectly through steam heated heat exchangers. Bear in mind solar energy is possible. The timber is stacked in chambers, called wood drying kilns, the process takes place here which is an enclosed area where the temperature is deliberatly regulated.
