The integrated freeze-drying chamber is a complete freeze-drying equipment that integrates pre-freezing, sublimation drying (freezing, vacuum, heating), and control systems. It freezes the material at low temperatures and directly sublimates the ice crystals in a high vacuum environment, thereby removing moisture and achieving low-temperature and highly efficient drying. This equipment features a compact structure and a high degree of automation. It can retain the original properties, active ingredients, and nutritional components of materials to the greatest extent and is widely used in fields such as biopharmaceuticals, food processing, and materials science.
