Difference between drying evaporation and dehydration
"Dehydrating agents remove water which is chemically bound to a substance for e.g water of crystallization. While on the other hand a drying agent simply removes excess water present in a substance which is not chemically bound to it. #pmgengineering #foodprocessing #foodindustry #foodtechnology #foodscience #engineering #science"
DIFFERENCE BETWEEN DRYING EVAPORATION & DEHYDRATION Definition of DRYING, EVAPORATION & DEHYDRATION DRYING - It is the process of removing water or other solvent from a solid, liquid, or gas. It is a physical change that occurs when moisture is lost from a substance. - is a process of It DEHYDRATION reducing moisture of food to low levels for improved shelf life. Dehydration is one food the oldest methods of of preservation. - is a form of It EVAPORATION vaporisation that usually happens on the surface of liquids and it involves the transition of the liquid particles into the gaseous phase. Difference between DRYING, EVAPORATION & DEHYDRATION DRYING DEHYDRATION EVAPORATION INITIAL COMPOUND A solid, semi solid or a liquid. A water- containing compound such as aqueous solutions. A solid, semi solid or a liquid. BY-PRODUCT Water or any other solvent. Water as an essential by product. Water as an essential by product. PROCESS Can use mild condition such as the application of hot air, sun drying etc. Need more controlled temperature and humidity conditions with sophisticated equipment. Can use mild condition such as the application of direct heat & basic equipment.
