What is Freeze Dry, What are its Application Areas? | Freeze Dry March

Lyophilization or freeze-drying is a low-temperature dehydration process that involves freezing the product, reducing the pressure, and then removing the frozen water from the product by sublimation. Freeze drying is in contrast to most conventional drying methods, which remove water from the product using heat.

Due to the low temperature used during freeze drying, the process results in a high quality product and the original shape of the product is preserved. Primary application areas of freeze-drying include biological (e.g. bacteria and yeasts), biomedical (e.g. surgical transplants), food processing (e.g. coffee), food preservation areas and museum recovery (e.g. books, wood, archaeological products, etc.) preservation of its content by dropping it).

Lyophilization is derived from the Greek term lyophile, “Solvent-Loving and Liquid-Absorbent,” and refers to the ability of a dry product to rehydrate at a high level.
