System Overview
Air is drawn into the dryer where the moisture is extracted from it. Moisture is
extracted when the air is passed through the evaporator coil. The coil is
cooled to a temperature lower than dew point temperature of the air and
hence condensation forms on it.
The dryer consists of 7 parts:
1. Fan motor draws the air through the unit.
2. Compressor which drives the refrigeration circuit.
3. Evaporator coil – cold section of the refrigeration circuit.
4. Condenser Coil – hot section of the refrigeration circuit.
5. Capillary tube – separates the hot and cold section of the refrigeration
circuit with regard to gas flow.
6. Auxiliary heater.
The STC1 Controller controls the power to the dryer and controls the amount
of water to be extracted by operating the compressor in accordance with the
drying control setting, i.e. : a 25% setting will run the compressor for 15
minutes in each hour. The fan runs continuously regardless of the drying
control setting. The auxiliary heater runs only when the thermostat setting is
greater than the kiln temperature, once the desired temperature is achieved,
the heater shuts off.
