    摘要: A dryer system comprising a particle counter that measures the level of particulates in the dryer is disclosed. The dryer system is particularly adapted for drying garments to be worn in clean room environments. The dryer system preferably comprises an enclosure having a rotatable drum for receiving and tumbling garments or other clothing, a fan and motor assembly for providing airflow through the drum, an exhaust duct near the drum and in communication with the drum, a sampling tube in the exhaust duct, and a particle counter for measuring the concentration of particles withdrawn through the sampling tube from the drum. A sampling line may optionally be incorporated in the dryer inlet for withdrawing one or more samples of inlet air and transferring to the particle counter. A check may then be made to ensure that the incoming air is sufficiently clean. The present invention also provides methods of controlling the dryer by a control unit utilizing a signal from the particle counter representative of the measured concentration of particulates in the dryer exhaust.

    摘要: Disclosed is a dryer device and a drying control system utilizing an infrared sensor that measures the temperature of garments or items being dried in a drying device. The invention provides significant improvement over conventional techniques using temperature sensors, or such sensors in combination with moisture or humidity sensors. Also disclosed are methods for controlling drying temperatures and methods for determining drying cycle completion.
