Advantages of four-ring lyophilization experimental lyophilizer to maintain substances

Now a lot of lyophilized products are being produced, thanks to the role of
lyophilizers.
The four-ring lyophilization experimental freeze dryer is a kind of refrigeration drying equipment
that can first freeze some water-containing substances into a solid state, and then sublimate the water in it from the solid state to a gaseous state to remove water and preserve the substance.
Freeze drying is a technology that uses the principle of sublimation for drying, which is a process
in which the dried substance is quickly frozen at low temperature, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor escape.
Advantages of
four-ring lyophilization experimental type lyophilizer.
1.
Low temperature drying is achieved at ultra-low temperature, so it is especially suitable for many heat-sensitive chemicals
.
Lyophilizers have been widely used in biomedicine, such as proteins, microbial strains, etc
.
2.
The volume hardly changes, and the original structure is maintained without extraction
due to dryness in the locked situation.
3
.
The loose porous structure of the chemical after drying in the refrigeration dryer is honeycomb and melts quickly after water release, and it is completely repaired almost immediately.
4.
Some chemicals that are convenient for air oxidation are maintained, because the lyophilizer dries very little
O2 under the vacuum pump.
5.
The lyophilizer has little damage when the freeze-drying ingredients dry at a lower temperature, and is suitable for the dryness
of some chemical raw materials, drugs and food.
6.
In the whole process of low-temperature drying, the growth and development of microbial strains and the role of enzymes cannot be carried out, so as to maintain the original characteristics
.
7.
The freeze dryer can remove more than 95-99% of the water, so that the goods can be stored for a long time after drying without easy quality change
.
8.
Carbonate melting chemicals originally melted in water, because the water in the raw materials is stored in the form of frost after pre-freezing, and is evenly distributed in the raw materials; 9.
After drying, the chemical substances are loose and porous, which is honeycomb-shaped, and quickly melts and completely after releasing water, and repairs the original almost immediately; 10.
Some dry irritability that is easily oxidized chemicals suffers from maintenance, and O2 is very small
due to dry irritability carried out under the vacuum pump.
