  • Patent number: 8978269
    Abstract: Disclosed is a hybrid drying system where a cold-air drier and a desiccant drier are combined to increase drying efficiency (extent of dehumidification/power consumption), thereby shortening drying time and significantly reducing operation costs. The hybrid drying system includes a desiccant drier installed between an evaporator and a condenser and having an absorbing part configured to produce dry air from the cold-air dried air which has passed through the evaporator and a detaching part configured to supply recycled air heated by the condensation heat of the condenser as a recycling heat source; a heat exchanger configured to heat-exchange exterior air with recycled exhaust air with the recycled air to retrieve exhaust heat; and a control unit configured to simultaneously control a cold-air drying operation and a desiccant drying operation according to the humidity and temperature of the drying chamber.
