The technology
Freeze-drying is a drying process at low temperature and low pressure, allowing sensitive products to be preserved. The solvent contained in the product is dried by sublimation (direct change from frozen to gaseous state) and the vapors are trapped on a condenser. This operation is normally carried out statically in cabinets with several shelves where trays containing the products are stored.
Our patented technology consists of first of all separating the freezing and drying stages. First, the product is frozen using liquid nitrogen. Then, the frozen product is agitated during its sublimation, which very quickly increases heat and material transfer. The product is agitated by a pendulum movement inside the sublimator and the condensation of the steam is carried out by another tank connected by flexible hoses.
Very low power consumption
Nitrogen freezing
Simplified and reduced air treatment
Flash freezing
Better survival rate for products from living organisms (viruses, cells, bacteria)
No oxidation/contact with oxygen
Limitation of product contamination risks
Limitation of human operations: loading and unloading made easy and automatable
Cleaning and sterilization (CIP)
Operator protection
Confinable complete system
Products confined in the freeze-drying tank
Possible automation of loading and unloading
Advantages
Dynamic freeze-drying
Reliability
Thanks to several families of proprietary patents and several years of development, our machines are adapted to the pharmaceutical field in terms of Good Manufacturing Practice.
High production quality
Mixing the frozen balls in the freeze dryer allows perfect homogeneity of the batch:
the heat is applied evenly thanks to the rotation of the machine, and the separation of freezing allows a better yield of living products.
Security
Production and staff. Operators are not exposed because the products are already “contained”:
- when freezing
- during freeze-drying
- when unloading
