Lyophilization, more commonly known as a freeze-drying process that removes water from a product after it is frozen and placed under high pressure is beneficial in many ways. The lyophilization process typically consists of three phases: freezing phase, primary drying phase, and secondary drying phase. At the freezing phase, a product is frozen, either in a dedicated freeze dryer or in a freezer at very low temperatures. Products in a dedicated freeze dryer or a freezer are frozen gradually to form large ice crystals. To prevent damaging materials that are structurally sensitive, such as cells, the freezing phase also employs a rapid cooling process to reduce ice crystal size. The primary drying phase includes reducing the pressure and application of a small amount of heat. At this phase, ice crystals undergo sublimation, a process of water transition directly from a solid to a gaseous state, without an intermediate liquid state. In this phase, about 95% of the water is removed from the frieeze-dried product. After this phase, the product results in a dry powder state. The secondary drying phase removes any remaining unfrozen water molecules adsorbed to the product by slightly increasing temperature. Products that undergo the freeze-drying process have many advantages that include the following: lighter mass and smaller volume compared with the original product; longer shelf life; easy reconstitution by adding water or buffer; high quality compared with products dried by other methods; convenient transportation and shifting due to lither weight and long shelf life.
