The small freeze dryer believes that everyone is familiar with it. Such a machine that integrates freezing and drying has always been favored by most experiments. The freeze drying principle of small freeze dryers is actually not complicated. Freezing and drying are divided into two processes The two processes are freezing and drying. Freezing is to process the material containing water, we first freeze it into a solid state. Then we perform the drying process, which is to convert the water in the frozen material from our solid state to the 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 moisture in the processed material, so that the processed material can be easily stored by us, and such storage will take a long time.
In the process of compressed air of the small freeze dryer, by reducing the temperature of the freeze drying of the compressed air, when the temperature continues to decrease, we can let all the moisture in the compressed air precipitate. In fact, the freeze-drying principle of a small freeze dryer is almost the same as the source flow of a domestic refrigerator. When compressed air passes through the compressed air pipe, the compressed air drops, thus meeting our drying requirements.
Several important parameters of the small freeze dryer should be paid special attention, and some of them are still the focus of attention. The daily use of the small freeze dryer must be checked from the following important parameters:
1. The number of partitions in the drying room The temperature of the partitions and whether there are debris in the drying room should be checked in time.
2. The gland function is good, and the manual and automatic functions are good.
3. Is there any change in the material of the condenser?
4. Whether the function of the compressor of the cooling system is normal.
5. Whether the parameter setting of the monitor is normal.
The design and use of small freeze dryers and inspections are important links for our use of small freeze dryers. We can strengthen the use and maintenance of small freeze dryers in many ways.
