Four determinants of drying efficiency of desiccant dryers
An outstanding dehumidification dryer has the following 4 factors to determine the drying power: drying temperature DryTemperatur, drying time Residtime, airflow, and temperature Dewpoint. These four elements are interlocked, and any change in conditions will affect the drying effect.
Residtime refers to the time when the material is pre-dried before it is formed. If the drying time is too long, it will cause material decay or agglomeration or waste power. If the dry time is too short, it will cause excessive moisture content.
Dry Temperature (DryTemperatur) refers to the temperature of the air entering the drying barrel. Due to its physical properties, such as molecular structure, specific gravity, specific heat, and moisture content, each material has certain constraints during drying. If the temperature is too high, it will The quality guessed that the local additives evaporate and decay or agglomerate. If they are too low, some crystalline materials will not reach the required drying conditions. In addition, insulation and heat preservation are required in the selection of dry barrels to prevent the loss of drying temperature, resulting in lack of drying temperature or waste of power.
Temperature (Dewpoint) refers to the temperature at which the moisture contained in the gas is condensed into droplets when the gas is cooled, a unit for measuring the dryness level of the gas. The less moisture in the gas, the lower the temperature.
Airflow is the only medium that takes away the moisture of the quality guess. The size of the airflow will affect the dehumidification effect. If the air volume is too high, the return air temperature will be too high and overheating will affect the stability of the desiccant dryer. If the air volume is too small, it will not be able to completely take away the moisture in the quality. The air volume also represents the dehumidification capacity of the desiccant dryer.
