The Efficient Freeze Dry Machine is an innovative marvel designed for the optimal drying of materials. This state-of-the-art freeze dry machine begins by freezing materials containing water at low temperatures. It then directly sublimates the water in a vacuum, expertly removing water vapor through condensation, ensuring the material is meticulously dried. The freeze dry machine is perfectly suited for the development and production of a variety of heat-sensitive biological products, including vaccines and medicines. It is also ideal for preserving the natural essence of fruits and vegetables through advanced vacuum packing techniques, and more. The dry machine boasts a compact structure, complete with fully automatic controls. It is easy to maintain and operate, offering several key benefits such as: 1. Operating in a vacuum state, it ensures the dried material retains the quality of its frozen counterpart. 2. Equipped with PLC controls and a touchable human-computer interface, it allows for real-time multi-channel temperature data recording during the drying process, with observations available in a detailed curve form. 3. The capability to preset the shelf temperature control curve facilitates seamless automatic sublimation.
