Dynamic freeze-drying
The technology
Freeze-drying is a low-temperature and low-pressure drying process which maintains all the qualities of sensitive products. The product’s wet matter is dried by sublimation (passing directly from the solid to the vapor state) and the vapors are trapped in a condenser.
The standard process is static, with products laid on trays.
The idea of Lyophitech is to agitate the product to improve and speed up the lyophilization by increasing all transfer operations.
Our dynamic patented technology consists in separating the freezing and the drying steps
Step 1: The liquid is pumped through nozzles to form fine drops into liquid nitrogen. . Pellets from 3 to 5 mm diameter are obtained.
Step 2: The pellets are loaded into the cylindrical shape sublimator for drying. Then the vacuum is pulled.

Benefits of the process
The process is more economical as the energy consumption is reduced by 20 to 40%, the time is reduced and the work is much less labor intensive (products are bulk loaded and unloaded).
La consommation énergétique est réduite de 20 à 40%
Besoin en main d'œuvre réduit
Procédé moins couteux qu'en lyophilisation statique
