Freeze Dryer

Description

Freeze-drying, freeze-drying or dehydration, is a dehydration process generally used to preserve a perishable food or make the material more suitable for transportation.
Freeze-drying works by 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, without passing through the liquid state. To speed up the process, freeze-sublimation cycles are used, which eliminate virtually all of the free water contained in the original product, while preserving the molecular structure of the freeze-dried substance.
This technique is mainly used in the food and pharmaceutical industries for the preservation of food and medicines. It is an expensive technique compared to traditional drying methods, but it results in higher quality products, since it fully preserves all the nutritional and organoleptic characteristics of the original product (aroma, flavour and medicinal properties).
For cryo-drying of up to 4.5 kilos per cycle.
