Working Principle
The freeze dryer utilizes the principle of vacuum sublimation. Materials are first pre-frozen at low temperatures; subsequently, a vacuum is applied, causing the ice to sublimate directly into water vapor. This vapor is then captured by a cold trap, resulting in dehydration at low temperatures while perfectly preserving the material's structure and biological activity.
