DDM SERIES Desiccant Dryer Mobile Drying of free-flowing granular plastic materials

Desiccant Dryer Mobile - DDM Introduction Labotek’s series of mobile desiccant dryers, DDM, is designed for the continuous drying of free-flowing plastic raw materials in granulate form. The DDM is available as a complete desiccant drying and integrated dry air conveying system to processing machine, based on proven, reliable & energy saving design. The standard temperature range is 60 to 140ºC with a preset deviation of +/- 2ºC. A HT (High Temperature) model is also available with a temperature range of 60 to 180ºC. Owing to the extremely accurate temperature control and a dew point of...

Drying The desiccant air blower (7) circulates the drying air in a closed system. The air is dried in one of the two desiccant beds (8) or (9), and the dew-point temperature is lowered to approx. -35°C. The dry air heating element (10) is used to heat the drying air to the required temperature before, via the air separator (6), it is distributed in the drying hopper DH (1). After the drying air has heated the raw material and transformed the moisture to water vapour, it is led back through the dust filter (11) to the blower (7). The humid air is cooled in the structural frame (12) of the...
