While freeze drying can accomplish many things, its primary goal is to protect the biological and chemical structure of a sample through the process of sublimation. Once complete, the sample can be used for testing, long term preservation, or in the case of food, eaten. In the laboratory, the applications of freeze drying are limitless.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Stages of Freeze Drying<\/strong><\/p>

There are three stages in the freezedrying\u00a0 process: Pre-freezing, primary drying, and secondary drying.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Pre-freezing<\/h6>

The pre-freezing stage is the most important stage of the freeze-drying process. In this stage, sample material will need to be cooled to at least the temperature of the melting point for that sample. This ensures the sample will be completely frozen and can then undergo sublimation. If the sample isn\u2019t frozen solid, evaporation will occur and the sample will not achieve the same preservation properties that occur with sublimation.\nThe rate at which sample freezes will affect the size of the ice crystals that form. If not done properly, it can impact the speed of reconstitution, length of the freeze-drying process and integrity and stability of your sample.\nLarger ice crystals facilitate faster and more efficient lyophilization because water molecules are able to move more freely out of the sample during sublimation. For samples like food or tissues, large crystals can break the cell walls and damage sample. In these situations, it is best for freezing to be done quickly through flash freezing, creating smaller ice crystals.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Primary Drying<\/h6>

With the low pressure environment, evaporative cooling of the sample begins, allowing for energy in the form of heat to speed the freeze-drying process. At the end of primary drying, roughly 93% of the water in the sample is sublimated out. For long term preservation of the sample, the run would continue on to secondary drying.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Secondary Drying<\/h6>

In the secondary drying phase, water molecules that are bound to the sample are released. Additional heat is added in this stage to drive off excess moisture, leaving behind a moisture content of about 2%. Secondary drying used for being prepared for long term preservation and storage.\nWhile freeze drying can accomplish many things, its primary goal is to protect the biological and chemical structure of a sample through the process of sublimation. Once complete, the sample can be used for testing, long term preservation, or in the case of food, eaten.
