Lyophilization

The fundamental principle in freeze-drying (also known as lyophilization), is sublimation, the shift from a solid directly into a gas. Just like evaporation, sublimation occurs when a molecule gains enough energy to break free from the molecules around it. Water will sublime from a solid (ice) to a gas (vapor) when the molecules have enough energy to break free but the conditions aren’t right for a liquid to form.
