1-2 Equipment Function
SDAP Series portable drying and conveying systems are used for automatic pneumatic handling
and drying of most free-flowing, dry, pelletized, or granular materials.
Sterling dehumidifying dryers are designed to generate heated, dehumidified air at carefully
controlled temperatures for use in closed-loop plastic drying systems. Moisture removal from
hygroscopic (moisture attracting) plastic pellets is an essential step in the manufacture of high-
quality plastic products. Sterling dehumidifying dryers are used to generate very low dew point
air heated to a controlled temperature for drying plastic pellets and regrind.
Sterling Mass Flow Series drying hoppers are engineered to be used with the dehumidifying
dryers. The dryer circulates hot air through the column of plastic resin in the drying hopper. The
resin in the hopper is discharged through a slide gate in a “first in, first out” manner. Material
conveying systems convey dry material from the drying hopper to a sight glass loader. The
optional drying hopper loader conveys material from a gaylord to the drying hopper.
SDAP Series Portable Drying and Conveying systems are sized to meet the specific requirements
stated by the purchaser at the time of purchase.
