Freeze-drying is a process in which moisture is removed from products in an especially gentle way. At first the material is going to be frozen and then dried under vacuum – the ice sublimates directly. This means it doesn't thaw, but instead turns directly into vapor. The result: color, taste, shape, and nutrients are almost completely preserved. If water is added later, the product shows excellent rehydration properties.

How it works

• Freezing to approximately -30 to -50 °C
• Setting-up a vacuum
• Sublimation – the frozen water turns directly from ice into vapor, leaving the product  the dried product

More elaborate than conventional drying, but significantly gentler and with better results.

Versatile applications

Freeze-drying is used in more fields than you might think:

⦁ Food: instant coffee, ready meals, outdoor snacks, fruit, baby food

⦁ Pharmaceutical industry: medications and vaccines that need to remain stable for long periods without cooling or at least without deep temperatures

⦁ Laboratories and biotechnology: bacterial cultures, enzymes, and samples are regularly freeze-dried to keep them stable and storable for years – an absolute standard process in many research and diagnostic labs

⦁ Pet food: nutrient-rich treats without artificial preservatives

⦁ Flowers: bridal bouquets and flowers, preserved permanently

⦁ Restoration: rescuing water-damaged books, documents, or archaeological findings

Advantages at a glance

Long shelf life – often several years, sometimes without cooling at all

Low weight due to moisture removal

Nutrients, color, and taste are preserved in best possible way

Easy rehydration – just add water
