There are many ways to dry wood. According to the way of moisture discharge in wood, it can be divided into three types: thermal drying, mechanical drying and chemical drying.
 
 
 
Thermal drying is a method of destroying the binding force between water molecules and wood by molecular vibration, and making water molecules evaporate or boil out of wood.
 
 
 
Mechanical drying is the way to discharge moisture from wood by centrifugal force or squeezing.
 
 
 
Chemical drying is the use of absorbent chemicals (such as sodium chloride) to absorb moisture in wood.
 
 
 
Among them, mechanical drying and chemical drying due to serious shortcomings, in addition to occasionally used as an auxiliary drying method, rarely used. The actual wood drying process adopts the thermal drying method.
