Sequentially arrange the steps involved in a drying curve:
A. Product reaches thermal equilibrium, evaporation rate rises as surface heats and free water mobilises.
B. Surface dries, rate drop, moisture diffusion from interior limits.
C. Linear moisture drop, but surface stay wet, evaporation rate will be constant until it reaches critical moisture constant.
D. Rate approaches zero when EMC matching air humidity, bound water remains.
E. Maximum drying rate achieved, unbound water evaporates steadily.
