Principle of vacuum freeze-drying
1. Definition and advantages of vacuum freeze-drying The product is completely frozen and the ice crystals are sublimated under certain vacuum conditions, thus achieving the purpose of low-temperature dehydration. This process is called freeze-drying The freeze-dried solid material exhibits a porous structure due to the sublimation of tiny ice crystals and maintains its original frozen volume. Upon addition of water, it easily dissolves and reverts to its original state.
The reasons for the leakage rate of the vacuum freeze dryer.
There are two indicators that can measure the sealing performance of a container in a vacuum freeze dryer: "rise rate" and "leakage rate". The pressure rise rate refers to the pressure change of a "vacuum" container over a certain period of time. The unit is usually mbar/s or mTorr/min. The calculation formula is as follows:
Key equipment for the preparation of freeze dryer
The freeze dryer is the core equipment for the preparation of functional materials, and the freeze dryer integrates a number of technologies such as low-temperature freezing, vacuum drying and precision control, which provides technical support for the development of new materials.
