A Vaccum Dryer is used for the mass transfer operation in which the moisture present in a substance (usually wet solid) is removed by means of creating vacuum. In chemical process industries like food, pharmaceutical, agricultural, textile, paper & pulp etc. drying is an essential unit operation to remove moisture.

Vacuum drying is generally used for the drying of those substances which are hygroscopic and heat sensitive and is based on the principle of creating a vacuum to decrease the pressure below the vapor pressure of the water. With the help of vacuum pumps, the pressure is reduced around the substance to be dried. This decreases the boiling point of water inside that product and, thus, increases the rate of evaporation significantly. The result is a significantly increased drying rate of the product.

In the pharmaceutical industry, the vacuum dryer is known by a common name called vacuum oven. The oven is divided into hollow trays which increases the surface area for heat conduction .The oven door is locked air tight by a high grade silicone seal and is connected to vacuum pump to reduce the pressure.
