The freeze dry machine represents an innovative and cutting-edge method for drying materials. This state-of-the-art technology freeze dry machine begins by freezing materials containing water at low temperatures. It then proceeds to sublimate the water directly in a vacuum state, effectively condensing and removing water vapor to achieve optimal drying of the material. The physical, chemical, and biological properties of the material remain largely unchanged. Minimal damage occurs to volatile components and nutritional elements that might otherwise degrade under heat. The processed material retains a porous structure and nearly the same volume as before, allowing large contact area; thus, when rehydrated, the material quickly returns to its original form and boasts an extended shelf life when stored in a sealed container. The freeze dry machine is ideally suited for the development and production of a wide array of heat-sensitive biological products, including vaccines, pharmaceuticals, fruits, and vegetables, with applications extending to vacuum packing and more.
The dry machine features a compact design, fully automated controls, and user-friendly maintenance and operation, offering several key advantages: 1. In a vacuum state, the quality of dried materials closely matches that of their frozen counterparts. 2. The PLC control system includes a touch-sensitive human-computer interface, enabling real-time monitoring and recording of multi-channel temperature data during the drying process, with data available for viewing in a curve format. 3. The shelf temperature control curve can be preset, allowing for the automatic sublimation process to proceed seamlessly.
