pakkasjäädytysjärjestelmiin
Pakkasjäädytys, also known as freeze-drying or lyophilization, is a dehydration process commonly used for preserving perishable materials or making them more convenient for transport. The process involves freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.
This method is particularly useful for preserving delicate biological samples, pharmaceuticals, and food products. Unlike other
The freeze-drying process typically involves three main stages: freezing, primary drying (sublimation), and secondary drying (desorption).
The resulting product is lightweight, has a long shelf life, and can be easily rehydrated by adding
