    A contamination-free drying environment. • Drying temperatures of 100° to 375°F (66° to 191°C). • Throughput rates of 15 to 100 lbs (6.8 to 37.3 kg) per hour (some materials can be run at a higher rate). • Dew points of -40°F (-40°C).

  • Page 113: How Conveying Works

    H o w C o n v e y i n g Wo r k s When the conveying function is turned on, the MDC uses dry air to move material from the drying hopper to the process machine as it is needed. Material enters the vacuum receiver and falls into the receiver and viewing chamber.
