The main factors affecting the drying efficiency of dehumidifying dryers
The drying power of an outstanding dehumidifier dryer determines the factors: drying temperature, drying time, air volume, and dew point. These four factors are interlinked, and any change in any condition will affect the drying effect.
1. Drying temperature refers to the temperature of the air entering the drying barrel. Due to its physical properties, such as molecular structure, specific gravity, specific heat, moisture content and other elements, the drying temperature has certain restrictions. When the temperature is too high, it will cause Some of the additives in the quality guess will evaporate and degenerate or agglomerate. Too low will make some crystalline materials unable to reach the required drying conditions, such as: PC/120℃, ABS/80～95℃. In addition, insulation and heat preservation are required in the selection of dry barrels to avoid loss of drying temperature, resulting in lack of drying temperature or power consumption.
2. The drying time refers to the time when the material is pre-dried before it is formed. Too long drying time will cause the material to decay or agglomerate or destroy power, and too short a drying time will result in excessive moisture content. For example: PC/3-4 hours, ABS/3-4 hours.
3. The air volume is the only medium that takes away the moisture in the quality guess. The air volume will affect the dehumidification effect. If the air volume is too high, the return air temperature will be too high, which will cause overheating and affect the stability of the dew point. If the air volume is too small, it will not be able to completely take away the expected moisture. The air volume also represents the dehumidification ability of the dehumidifier dryer.
4. The dew point temperature refers to the temperature at which the moisture contained in the gas is condensed into droplets when the gas is cooled. It is a unit for measuring the degree of dryness (moistness) of the gas. The less moisture in the gas, the lower the dew point temperature.
