The freeze dry machine represents a cutting-edge technology for the efficient drying of various materials. This remarkable freeze dry machine ingeniously begins by freezing materials with water at low temperatures, then it directly sublimates the water in a vacuum state, effectively removing water vapor through condensation to leave the materials perfectly dried. This method ensures that the physical, chemical, and biological properties of the materials remain unchanged. Compared to traditional heating methods, it significantly reduces the risk of damaging volatile compounds and denaturing nutritional elements. The processed material becomes porous, retaining nearly the same volume as before. Due to its large surface area, it rehydrates swiftly when water is added, and boasts an extended shelf life when stored in sealed containers. This versatile freeze dry machine is ideal for a wide range of applications, particularly in the development and production of heat-sensitive biological products including vaccines, pharmaceuticals, and naturally preserved fruit and vegetable vacuum packaging.
The state-of-the-art dry machine is designed with a compact structure, offering full automation, easy maintenance, and simple operation. It boasts several key advantages: 1. Operating under a vacuum state, it ensures the quality of dried materials is comparable to that of frozen ones. 2. Equipped with PLC control and an intuitive touch-screen interface, it provides real-time recording of multi-channel temperature data during the drying process, with the ability to view it in a curve format. 3. The shelf temperature control curve can be preset to facilitate automatic sublimation, ensuring optimal drying results.
