The process of freeze drying is otherwise called lyophilization, cryodesiccation or lyophilisation. It can be a process of dehydration that may be ordinarily utilized inside the preservation of products that happen to be perishable, as it tends to make it considerably more transportable. How it functions is by means of the freezing of the product, after which there is a reduction on the pressure that surrounds it.

There is a significant cavity where the freezing of the product is done, also as a vacuum pump that is certainly used to take away the water/moisture form the product. Just after this really is accomplished, then there's the application of heat that serves to speed up the sublimation process. There is then condensation, wherein the vaporized solvent is removed from the chamber with the vacuum using the conversion on the solvent to a strong state. When this can be done, the separation from the water/moisture from the product has been completed.



Because the 1960s there have been greater than four hundred finds of freeze-dried foods which have developed on a commercial level.
