I began to hear that when I was lyophilized, I was puzzled by hot drying, but it seems a little impossible to freeze-dry. Let us look at how freeze drying is applied to the technology of vacuum dryers. After reading it, I must be able to lift the doubts in everyone's mind....
For the freeze dryer, everyone is familiar, but the freezing principle is certainly not very familiar, today Xiaobian will explain the principle of freeze-drying curve of freeze dryer, let's learn together!...
There are two traditional methods for the treatment of moisture in the gas source. One is that the adsorbent absorbs the water in the gas source, and the resulting equipment is an adsorption dryer; the other is by lowering the gas temperature to below the dew point temperature. The water in the air is condensed into a liquid and then separated to reduce the water content in the gas source, and the resulting equipment is a freeze dryer....
After the quick-frozen raw materials are selected, rinsed, shaped, and placed in the previous process, they can enter the freeze-drying stage. The first step of lyophilization is to freeze the lyophilized material, and place the material tray in the lyophilizer for quick freezing (some lyophilizers do not have a quick-freezing function, and a quick-freezer is required)....
The freeze dryer is one of the drying methods for the purpose of storing articles. The reason why the article will be damaged, rotted and deteriorated is mainly due to the external factors and internal factors, the external factors, the role of air, water, temperature, and biology; the internal cause is mainly the metabolism of the biological material itself....
