Introduction to the drying principle of bench-top type Freeze Dryer
The bench-top type Freeze Dryer is no stranger to everyone. Such a machine that integrates freezing and drying has been favored by most experiments. The principle of freeze drying of the bench-top type Freeze Dryer is actually not complicated. Freezing and drying are divided into two These two processes are freezing and drying respectively. Freezing is to freeze the processed substance containing moisture, we first freeze it into a solid. Then we perform the drying process, which is to convert the moisture in the frozen material from our solid to gaseous state. We call this a sublimation process. Such a process is actually a drying process.
Through such a method, we can easily remove the water in the processed substance. In this way, the processed substance can be easily stored by us, and such preservation will take a long time.
In the process of compressed air of bench-top type Freeze Dryer, by lowering the freeze-drying temperature of compressed air, when the temperature continues to decrease, we can let out all the moisture in the compressed air. In fact, the freeze-drying principle of the bench-top type Freeze Dryer is almost the same as the source flow of the domestic refrigerator. When compressed air passes through the compressed air pipe, the compressed air drops, thereby meeting our drying requirements.
Several important parameters of bench-top type Freeze Dryers should be paid special attention to. Some of them are still the focus of great attention. Daily use of bench-top type Freeze Dryers must be checked from the following important parameters:
1. The number of partitions in the drying room of the bench-top type Freeze Dryer. The temperature of the partitions and whether there is any debris in the drying room should be checked in time.
2. Whether the gland function of the bench-top type Freeze Dryer is good, and whether the manual and automatic functions are good.
3. Are there any changes in the material of the condenser of the bench-top type Freeze Dryer?
4. Is the compressor of the cooling system functioning properly?
5. Whether the parameter setting of the monitor is normal.
The design and use of bench-top type Freeze Dryers as well as the inspection are important aspects of our use of bench-top type Freeze Dryers. We can strengthen the use and maintenance of bench-top type Freeze Dryers from multiple aspects.
