Top 6 Things You May Not Know About Freeze Dryers
1. Some zoos use freeze dryers to increase the concentration of tranquilizers so that they work for larger animals such as bears or even elephants.
2. Andean civilizations preserved potatoes using a freeze drying (also known as lyophilization) process. This food was called chuño.
3. During the Second World War, serum being sent from the US to Europe for treating wounded soldiers needed to be refrigerated, but because refrigeration technology did not exist in transport vehicles at the time, many serum supplies were spoiling before getting to hospitals. This led to the freeze-drying process being developed for commercial use in order to make serum chemically stable so that, even without refrigeration, it could be transported without going bad.
4. Freeze drying has been used to restore documents that have been damaged by water.
5. Freeze dryers have also been utilized to prepare river-bottom sludge for hydrocarbon analysis and in producing synthetic skin.
6. The restoration of historic/reclaimed boat hulls is another process that uses freeze dryers.
