The LD-82 dehumidifier process dryer consists of a motor-compressor unit, a
refrigerant condenser, air circulating fans, a refrigerated surface, and a means
of collecting and disposing the condensed moisture and a cabinet to house
these components.
The fan draws air through the refrigerated surface and cools it below its dew
point, removing moisture which is collected and led away. The cool air then
passes the hot condenser, where it is reheated (with the same energy
removed during the cooling phase). With the addition of other radiated heat
and extra heat (if required), from an electrical heater bank, the air is
discharged into the chamber at a higher temperature but lower relative
humidity than when the air first entered the process drying unit. Continuous
circulation of the chamber air through the LD-82 dehumidifier process dryer
gradually (under controlled conditions), reduces the relative humidity, thereby
drying the product.
