In short

Freeze-drying (lyophilisation) removes water from food by turning ice directly into vapour. The product is not heated, so it keeps its nutrients, taste, colour and structure and lasts a long time without preservatives. We sell Utily-FD freeze dryers under our own brand in five sizes from 20 to 200 m² of drying area.

Benefits

Why freeze-dry

Preserves nutrients

Vitamins, minerals and enzymes are preserved because the product is not heated as in conventional drying.

Taste, aroma and shape

The product keeps its original structure, colour, taste and aroma.

Long shelf life

Without water, microorganisms cannot grow and oxidation stops. No preservatives.

Low weight

Removing water cuts weight by up to 90 %. Cheaper transport and storage.

Easy rehydration

Add water and the product quickly returns to its original form.

Wide range of uses

Fruit, vegetables, meat, fish, dairy products, herbs, pet food.

How it works

The freeze-drying process

  1. 1

    Freezing

    Raw material contains 80–95 % water. It is first deep-frozen so the water turns into ice crystals.

  2. 2

    Primary drying (sublimation)

    At very low pressure, ice turns directly into vapour with no liquid phase. Controlled temperature protects the product's structure.

  3. 3

    Secondary drying (desorption)

    The remaining bound water is removed down to the required moisture content.

  4. 4

    Packaging

    The finished product is packed in airtight packaging that protects it from moisture.
