What is Freeze-Drying Technology?
We produce in our state-of-the-art facility via employing a unique and innovative technology which is called freezedrying. Fundamental principles in freeze-drying comes from the sublimation process. Sublimation is a phase transition process from a solid to a gas without ever entering an intermediate liquid phase.
In our freeze dryers, moisture is removed from the product
up to 99% under low vacuum and low temperature. Vacuum environment that is created by our freeze dryers to lower the air pressure in their chambers and initiates the phase change of water from ice crystals to gaseous without melting which has a significant impact to prevent the mushy and shrivelled appearance in finished products. That is why freeze-dried products still looks like a fresh product, instead of a mushy shape.
Since vacuum makes sublimation possible under low temperature, freeze-dried products preserve its shape, aroma, flavour, colour, vitamin retention and nutrient content. Thus, freeze-drying is known as the best drying technique for heat-sensitive foods.
