Freeze drying - Wikipedia
WebFreeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process [1] that involves freezing the product and lowering pressure, thereby removing the ice by sublimation. [2] . This is in contrast to dehydration by most conventional methods that evaporate water using heat. [3]
What is Lyophilization? - Millrock Technology, Inc
WebLyophilization is a water removal process typically used to preserve perishable materials, to extend shelf life or make the material more convenient for transport. Lyophilization works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to sublimate. Lyophilization’s 3 Primary Stages.
What is lyophilization? - Its Process and Application
WebJul 28, 2023 · Lyophilization is a sophisticated dehydration procedure that involves eliminating water or solvent from a material by changing it from a frozen to a gaseous state without going through the liquid phase. This is accomplished by sublimation, which occurs when ice or a solvent transforms from a solid to a vapor without becoming a liquid.
