SCD-ES

SCD-ES "All-In-One" Energy Saving Compact Dryers integrate plastics dehumidifying, drying and conveying into one unit, and especially suitable for processing hygroscopic engineering plastic materials, such as PA, PC, PBT, PET etc. All models adopt silica gel honeycomb-rotor which can provide dry air with dew-point below -40℃.

Working Principle

The hot and moist air returning from the drying hopper blows into the honeycomb-rotor. The moisture contained in the air is absorbed by the rotor, and then be desorbed by the regenerated hot air. The two air streams take effect on the rotor. With rotation of the rotor, the moisture in the air will be absorbed anddesorbed by the regenerated air and drains out continuously, forming air with stable low dew-point. And the air will be heated to the drying temperature of plastics, and blows into the drying hopper to form a closed loop.

Features：

• Adopts silica gel honeycomb-rotor. The regeneration temperature is 150℃, and regeneration power consumption is 30% less than that of molecular sieve dehumidifier. It avoids the problem that silts resulting from aging of barrel or rotary molecular sieve blows into the storage tank which may contaminate plastics. (The double-cooler design has now patent protection).

• Panel-type heat exchanger reduces total power consumption by 20~25%.

• The function of dew-point temperature setting is available. The dew-point temperature is set at -40~+10℃according to the desired temperature of materials which can save power consumption by 0~10%. (Using regeneration temperature to control dew point of the drying air being applied for a patent).

• The function of drying capacity control. Set the name of material and hourly consumption, then the system will adjust drying air flow and power consumption automatically. When hourly material consumption accounts for 20~100% of rated drying power, the total power consumption of the machine will be reduced by 0~40% to reach an optimal allocation of energy. It also prevents over-drying which may influence physical and mechanical properties of materials.
