The Airontek Freeze Dryers are the ideal solution for those looking for a reliable, efficient, and versatile cold-drying system. Thanks to lyophilization, it is possible to preserve the nutritional values, color, aroma, and active ingredients of materials intact, ensuring long-term storage without the use of chemical additives.

What is a Freeze Dryer used for

A freeze dryer removes water from food and raw materials through a process of freezing and sublimation. This method allows the original characteristics of the product to be maintained, making it light, stable, and ready to be rehydrated in just a few seconds.

  • Food industry: preservation of fruit, vegetables, meat, dairy, ready meals.
  • Pharmaceutical: maintaining the stability of sensitive active ingredients.
  • Herbal and cosmetics: gentle drying of plants, flowers, and raw materials.

How it works

  1. Freezing: the product is cooled down to -45 °C.
  2. Sublimation: under vacuum conditions (15 Pa), water passes from ice to vapor.
  3. Final drying: the material is stabilized with minimal residual moisture.

The result is a crunchy, lightweight, stable and easily rehydratable product, ideal for industrial and professional applications.

Advantages of freeze drying

  • Extended shelf life without additives.
  • Preservation of nutritional and organoleptic value.
  • Up to 90% weight reduction for transport and storage.
  • Instant rehydration.
  • Versatility of use in different sectors.
