freeze-dryingThe vacuum freeze-drying technology, which originated in the 1820s, experienced decades of ups and downs and made significant progress in the following 20 years. In the 21st century, vacuum freeze-drying technology has become increasingly popular due to the advantages of other drying methods. In addition to being widely used in the fields of medicine, biological products, food, blood products, and active substances, its application scale and fields are still expanding. Therefore, vacuum freeze-drying will inevitably become an important application technology in the 21st century.
freeze-dryingFreeze drying (hereinafter referred to as freeze-drying) is a method of preserving a substance by first freezing it into a solid state, and then sublimating the water from the solid state to a gaseous state, in order to remove the water and preserve the substance.
In the process of compressed air drying, freeze-drying is achieved by reducing the temperature of the compressed air to remove moisture from it. The working principle of a freeze dryer (refrigerated dryer) is the same as that of a refrigerator. After the compressed air passes through the frozen compressed air pipeline, the temperature of the compressed air drops to the required temperature to meet the drying requirements.
freeze-dryingKey Features:
Pre freeze-drying is carried out in situ, reducing the tedious operation of the drying process and achieving automation of the freeze-drying process;
Silicone oil, as a circulating medium, has high temperature control accuracy, shelf temperature difference ≤ 1 ℃, and uniform drying effect;
The shelf temperature can be adjusted, controlled, explored, tested, and produced using advanced technology;
L can store 32 programs, each with 36 segments. The freeze dryer can modify program parameters during operation and record the drying curve after operation;
Touch screen operation, PID control, display drying curve;
The square tray is not easily deformed, easy to operate, and easy to clean;
Configure an inflation valve that can be filled with dry inert gas;
The drying room adopts high transparency, colorless and transparent organic glass doors, which can clearly observe the process of material changes during operation;
Optional cooperation with eutectic point testing device.
