Project Description
An innovative process consisting of two stages: «spray congealing» and dynamic freeze drying that enables dynamic drying of the bulk material and the generation of freeze-dried microspheres. In the dynamic freeze drying process the frozen fluid is freeze-dried in a rotary freeze dryer under constant gentle mixing. Sublimation energy is transferred by radiation and temperature-controlled surfaces. This process eliminates the typical limitations of conventionally freeze-dried products, such as poor flowability and poor dosing properties, inhomogeneity and dust emissions during handling. The drying conditions are extremely uniform thanks to constant gentle mixing of the product.
