What Is Freeze Drying?

Freeze drying is also known as lyophilization. When you freeze dry something you are basically getting rid of all the water and liquids to be able to preserve it. This process is known as dehydration. In order to freeze the skin you have to lower the pressure to allow the heat to convert a solid into a gas.

Freeze Drying Process

There are three basic steps to freeze drying. The first step is freezing, followed by primary drying and lastly there’s the secondary drying stage. Freezing which is the most important step can be achieved with liquid nitrogen or in a bath of dry ice and methanol (CH3OH). Methanol has a tetrahedral shape and is part of the organic groups of alcohol. The primary and secondary drying involves sublimation and adsorption.
