    • Honeycomb Rotor & Drying/regenerated Electric Heat

      As the key part of the machine, honeycomb rotor plays functions of dehumidifying and lowering the dew-point temperature of air; it’s made of whole molecular sieve, which enable the air dew-point to lower to -40℃ after dehumidifying. Working together with drying/regenerated electric heat, it can achieve continuous operation of dehumidifying and drying.

    • Drying/regenerated Blower

      The drying blower blows the dehumidified air to the drying electric heat for heating and then sends it to material tank to be the power source for dehumidifying air in the drying circuit. The circulating blower sends the air to the regenerated electric heat for heating and then blows it to the honeycomb rotor to get the moisture absorbed by the honeycomb rotor evaporated, which will make the honeycomb rotor capable of moisture absorption again.

    • Control Panel

      Used for setting the drying temperature; adopt microcomputer control panel with P.I.D temperature control technology and LED display to precisely control temperature.

    • Cooler

      After the return air going through the cooler, its temperature will decrease, which is helpful for honeycomb rotor to better absorb moisture. Generally, it’s required that the temperature of return air be lower than 35℃.
    SDD dehumidifying dryers integrate dehumidifying and drying into one unit, which mainly process high efficient drying for hygroscopic plastics, such as PET, PA and PC. The floor mounted SDD collocated with loader and suction box beside the IMM can realize auto dehumidifying and drying. Besides, this machine can also be placed at the central material area to work with central material system for centralized drying processing. In addition, there’re multiple options and accessories to meet various demands. If some dry materials are volatile, it must use the EOF filter.

    Features

    • Adopt molecular sieve structure honeycomb, which provides low dew-point dry air.The honeycomb rotor structure is superior to double-barrel dehumidifier that will contaminate raw material due to damaged molecular sieve.
    • Dehumidifying and drying function are integrated to ensure high efficiency.
    • Insulated drying hopper features dry air down-blowing and cyclone exhaust design. This improves drying efficiency and reduces heat loss, saving energy.
    • The dehumidifying section of the SDD series adopts cooler to ensure a low return air temperature and low dew-point.
    • Microprocessor is the standard equipment,with a temperature controlling accuracy of ±1℃.
    • Equipped with weekly timer, machine can automatically operate.
