Also, moisture content is divided into “critical moisture content” and “equilibrium moisture content”.“critical moisture content” is the moisture content during a transition from constant rate period to falling rate period which are mentioned in the article “About drying process” issued on 13 th June.It suggests moisture content when drying of outer material is done and drying of inner material starts.
Also, “equilibrium moisture content” suggests moisture contents at which material does not lose its moisture any more.This can be said that water inside a material is balanced in surrounding air with constant humidity and temperature, in other words, it is a moisture content with the same humidity as surrounding air.
