what is difference between dehydration and drying?
Answers
Answer:
Drying means to get rid of the free water in a given compound. ... A drying process requires simple method of moisture removal like sun-drying whereas dehydration is a controlled method of removing moisture (controlled temperature and humidity) , commonly using sophisticated equipment.
Answer:
The key difference between drying and dehydration is that the drying refers to the removal of solvent from a solid, semi-solid or a liquid whereas dehydration refers to the removal of water from the water-containing compound.
Both terms drying and dehydration refers to the removal of solvent from a solution, thereby leaving only the solute. Therefore, both these processes are mass transfer processes. Moreover, these processes will leave a solid residue at the end.

What is Drying?
Drying is the process of removal of solvent from a solid, semi-solid or a liquid. Hence, it is a mass transfer process because the solvent mass in the solution moves from the solution to the atmosphere via drying. Here, the solvent can be water or any other solvent such as organic solvents. Also, this mass transfer occurs via evaporation. Often, we use this process as the final step before the packaging of some products. The final product of the drying process is always solid. It can be in continuous sheet form, in long pieces, particles or as a powder.
