frysetørksyklus
Frysetørksyklus, also known as freeze-drying or lyophilization, is a dehydration process commonly used to preserve perishable materials or make 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 is in contrast to a conventional dehydration method, where the material is dried by evaporation.
The typical freeze-drying cycle involves three main stages: freezing, primary drying, and secondary drying. Freezing is
Freeze-drying results in a stable, dry product that retains much of its original structure, flavor, and nutritional
