What Factors Affect The Load Of The Freeze Dryer
- Jul 12, 2017 -

Freeze drying of Freeze Dryer technology in the biological engineering, pharmaceutical industry, food industry, materials science and deep processing of agricultural and sideline products and other fields have a wide range of applications. In the Freeze Dryer process, the growth of microorganisms and the role of enzymes can not be carried out, so to maintain the original sexual equipment. Since the drying is carried out in a frozen state, the volume is almost constant, and the original structure is maintained, and the concentration does not occur. After drying the material loose porous, sponge-like, dissolved after the water quickly and completely, almost immediately restore the original traits.

The freeze dryer is carried out at low temperatures and is therefore particularly suitable for many heat-sensitive substances. Such as protein, microorganisms and the like will not be degeneration or loss of biological vitality. So it is widely used in medicine.

The load of the freeze dryer depends on the amount of water to be treated, and the higher the water content, the higher the load. Therefore, the working load of the freeze dryer is directly related to the flow rate of the compressed air being treated, and the most influential parameters for the Freeze Dryer machine load are:

1. Intake temperature: the higher the temperature, the more water the water, the higher the freeze dryer load;

2. Working pressure: Under the same temperature conditions, the lower the saturated air pressure, the more water content, the higher the freeze dryer load.

In addition, the relative humidity of the air compressor under the inspiratory environment is also related to the saturated water content of the compressed air, and therefore also affect the freeze dryer load: the greater the relative humidity, saturated water contains more water, the higher the load The
