|
Divided into 3 periods according to the drying rate.

|
|
Study at the condition of constant temperature and relative humidity in drying.
|
|
|
Study at the condition of heat transfer by hot air
|
|
|
Study at the condition of thermal conductive heat transfer
|
Explanation:
Detailed explanation-1: -Drying is an energy intensive process involving simultaneous heat and mass transfer [3]. Additionally, during this process, there is a movement of heat by convection from the drying medium to the material which permeates the material by conduction.
Detailed explanation-2: -Thermal conductivity values are numerical values that are determined by experiment. The higher that the value is for a particular material, the more rapidly that heat will be transferred through that material. Materials with relatively high thermal conductivities are referred to as thermal conductors.
