The main principle involved in freeze drying is a phenomenon called sublimation, where water passes directly from the solid state (ice) to the vapour state without passing through the liquid state.
Lyophilization drying is a method of extracting the water from Biological samples, foods and other products so that foods or products remain stable and are easier to store and preserved at room temperature.
