Drying agents absorb the moisture contents from a substance, where as dehydration removes the water molecules, hence totally a new product is formed
Karl Fisher Titration measures only the water content in a product sample. Loss on drying measures the total loss in weight of a material as a result of drying.?æ
In evaporation water boils until it reaches it boiling point while drying just passage of heat until the substance get dried EVAPORATION IS PARTIAL REMOVAL OF WATER FROM THE COMMODITY .WHILE DRYING IS THE COMPLETE REMOVAL OF MOISTURE FROM THE COMMODITY..
In the laboratory, it may be used as a milddrying agent where other drying agents, such as calcium chloride and magnesium sulfate, may be incompatible. It is not suitable for acidic compounds, but can be useful for drying an organic phase if one has a small amount of acidic impurity.
Freeze-drying (also known as lyophilization or cryodesiccation) is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure and adding enough heat to allow the frozen water in the material to sublime directly from the solid phase to gas.
assay on as is basis includes the weight of water, residual solvents, moisture absorbed, if any. but assay on dried basis will remove all athe above by drying the sample under analysis.
we can control conditions in dehydration where as in case of drying we can't.
Answer:Sun-drying, tunnel dehydration, vacuum-drying, and osmotic dehydration.
Dehydration is removing water from food- drying it.

A dessicant
because carbohydrates(sugars) are hydrates of carbon.
drying agent absorbs the water content while dehydrating agent lost the water content.
Drying is a method of food preservation that works by removing water from the food
Karl Fisher Titration measures only the water content in a product sample. Loss on drying measures the total loss in weight of a material as a result of drying.?æ
Drying continues until the dehydration is complete.
it is a certain products require a porous structures to facilitate dehydration , otherwise they may suffer heat or oxidation damage during drying even at room temperature ..
Drying agents are chemicals or substances which aid the removal of moisture. They are used in a variety of applications like the manufacture of medications and chemical compounds.
