HARVEST RIGHT - FREEZE DRYER MEDIUM

Freeze-drying, dehydration or cryo-drying, is a dehydration process generally used to preserve a perishable foodstuff or make the material more convenient for transport.

Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the water frozen 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 whereby practically all the free water contained in the original product can be removed, but preserving the molecular structure of the freeze-dried substance.

This technique is mainly used in the food and pharmaceutical industry for food preservation. It is an expensive technique compared to traditional drying methods, but results in higher quality products, as it completely preserves all the nutritional and organoleptic characteristics of the original product (aroma, flavour and medicinal properties).

FREEZE-DRYING PROCESS

1. The products are placed in the freeze-dryer and frozen at -40°C.

2. Once frozen, the freeze dryer creates a vacuum around the product and the ice turns to steam and evaporates (vacuum pump included).

3. The freeze-dried product should be placed in an aluminised container or storage bag with an oxygen absorber (such as Air Out Oxigen) to ensure freshness until the day you wish to consume it.
