Freeze-drying device

A freeze drying device comprising:

• an evaporation chamber comprising means for heating said evaporation chamber configured to perform a sublimation of the solvent contained in the frozen products intended to be disposed in said evaporation chamber, said evaporation chamber being mounted so as to be rotated on a shaft;
• at least one condensation chamber in communication with said evaporation chamber, and comprising means for cooling said condensation chamber configured to transform the vapour coming from said evaporation chamber into ice;
• a product inlet and a product outlet connected to said evaporation chamber by first flexible connectors, the product inlet and product outlet being fixedly mounted relative to the evaporation chamber, and
• a motor which drives said shaft back and forth on itself according to:
• a first movement driving said shaft in a first direction of rotation with an angle of rotation of between 5° and 90°;
• and
• a second movement driving said shaft in a second direction of rotation, opposite the first angle of rotation, with an angle of rotation of between −5° and −90°;
• wherein said at least one condensation chamber is fixedly mounted relative to said evaporation chamber, said evaporation chamber and said at least one condensation chamber being connected by second flexible connectors.
