  • Patent number: 9200840
    Abstract: Disclosed herein are a clothes dryer and a control method thereof in which a drying time is adjusted according to wool content during a drying cycle of a wool course. Wool content of woolen textiles is judged by sensing a dryness of the woolen textiles during a drying cycle of a wool course, and a drying time is adjusted according to the wool content, thereby minimizing contraction or deformation of the woolen textiles while satisfying the range of a target dryness set by wool mark standards. Further, only a high-capacity heater is driven during the drying cycle of the wool course, thereby allowing an internal temperature of a rotary drum to keep the optimum temperature without contraction or deformation of the woolen textiles.

  • Patent number: 6640462
    Abstract: Disclosed is a method of drying timbers loaded in a drying chamber, which comprises the steps of heating the drying chamber by a heating system up to a temperature of 80 to 100° C., subjecting the timbers to vacuum blowing by connecting the inside of the drying chamber with a vacuum chamber (receiver) evacuated by a rotary pump until the inside pressure of the drying chamber drops to 1 to 10 mmHg, disconnecting the inside of the drying chamber from the vacuum chamber, connecting the drying chamber with the atmosphere. When the inside of the drying chamber is connected with the vacuum chamber, the moisture content of the timbers is sharply reduced, so that their temperature sharply drops. Thereafter, when it is disconnected from the vacuum chamber, and connected with the atmosphere, the inside temperature of the drying chamber is again increased. Meanwhile, the heating system is worked during the whole process.

The drying zone is supplied with super heat from the super heat exchanger, and the condenser is supplied with working medium from a super heat exchanger, thereby increasing the temperature in the drying zone.

  • Patent number: 5343633
    Abstract: A process and apparatus are described for rapidly drying a wet, porous gel monolith of glass or ceramic, at subcritical temperatures without inducing any cracking of the gel. The wet gel is immersed in a liquid solvent in a chamber, and the liquid solvent is then heated and expelled from the chamber. Further heating, with or without the presence of a flowing inert gas, fully dries the wet gel. When an inert gas is used, the gas is delivered to the chamber with a controlled solvent partial vapor pressure, to correspondingly control the driving force for drying the gel.
