Explanation: 

Detailed explanation-1: -The kiln process involves the drying of wood in a chamber where air circulation, relative humidity and temperature can be controlled so that the moisture content of wood can be reduced to a target point without having any drying defects.

Detailed explanation-2: -The process of drying out the water from “wet” or “green” timber is termed “seasoning", or more simply “drying". Water is just as essential to the life of a tree as it is for all living matter.

Detailed explanation-3: -Most of the moisture in green timber is what we call ‘free water’ meaning it simply occupies the wood cells and voids between them. As timber begins to dry out the free water is drawn to surface and evaporates leaving only the water that is bound into the cell walls. This stage is called the Fibre Saturation Point.
