Lyophilisation

Lyophilisation, or freeze-drying, is a dehydration process at low temperatures under vacuum conditions.

In the lyophilization process, the raw material is rapidly frozen, followed by a pressure reduction in the lyophilization chamber to a vacuum below 1 mbar, initiating the sublimation process. During this process, the water in the product transitions directly from a solid (frozen) to a gaseous state through sublimation. The ice present in the frozen product is transformed into a gaseous state and directed to a condenser, effectively removing moisture in vapor form from the raw material.

Advantages of the Technology

The key advantage of lyophilisation technology lies in preserving up to 98% of the biologically active compounds present in the material being dried. síbiotech employs lyophilisation to dry microalgae, fungi, berries, fruits, medicinal plants, and their processed products. This approach allows for retaining the material’s favourable properties and biological functionality, distinguishing it from conventional drying technologies.

síbiotech primarily utilises lyophilisation technology to prepare raw materials for supercritical fluid extraction to obtain biologically active compounds.

For extraction to be effective and standardised, high-quality raw materials with a high concentration of biologically active compounds and minimal moisture content are essential.
