  • Patent number: 8869420
    Abstract: This invention presents a versatile and continuous drying technology that utilizes controlled heat combined with forced air supply for drying a feedstock. The dryer virtually divided top-down into different zones, each having definite heated air distribution rate to secure desired condition for drying of the feedstock. The heat source of the dryer is waste heat, either provided by the feedstock itself through exothermic heat generated by the feedstock or reclaimed waste heat or solar heat. The discharge system of the dryer is a fail-safe discharge system, which ensures equal residence time for the feedstock through all the zones.

  • Patent number: 7882647
    Abstract: One type of dryer, namely a laundry dryer (1), comprises a water tank (20) and a drum (30). At the time of drying laundry, the interior of the drum (30) functions as a hermetically closed drying chamber (170). The air in the closed drying chamber (170) is sucked into a circulation duct (171) and heated by means of a heater (173) to a hot air before being blown into the closed drying chamber (170). The hot air having absorbed moisture from the laundry comes into contact with dehumidification water in a cooling chamber (174) within the circulation duct (171), thereby being dehumidified. The dehumidification water is sprayed by a mist generator (180). In the drying process, the mist generator (180) generates mist of metal ion water which has passed through an ion dissolving unit (100) and sprays the mist to the laundry.

  • Publication number: 20110016743
    Abstract: A dryer control method includes: a first dry step of drying a dry item with strong hot wind while tumbling a drum in which the dry item is placed; and a second dry step of drying the dry item with mild hot wind while tumbling the drum. Because the dry process is repeatedly performed on the dry item according to a proposed dry algorithm, the dry item made of wool fiber can be prevented from being shrunken or creased in the dry process.

  • Publication number: 20110010961
    Abstract: A drying device has been developed having a single electric motor configured to drive a drum and directly drive an air blower. The single electric motor is a non-line frequency electric motor. The drum is coupled to a support frame to enable rotation of the drum relative the support frame. The drum has an interior space for holding a load of articles, such as clothing. The motor includes a controller configured to increase gradually the angular velocity of the drum to provide a “soft start” for the dryer.

  • Publication number: 20100319213
    Abstract: The present invention relates to a hot air generating apparatus and a dryer having the same. The hot air generating apparatus comprises a temperature sensing unit, and a gas supply unit controlling a flowing amount of gas to be supplied according to a temperature of hot air sensed by the temperature sensing unit, wherein when the temperature of the hot air sensed by the temperature sensing unit approaches a pre-set threshold value, the flowing amount of gas to be supplied is gradually reduced, thereby being capable of continuously supplying hot air without being frequently turned on/off.

  • Publication number: 20100170101
    Abstract: A cloth dryer includes heat-pump (30), rotary tub (5) for accommodating clothes (4) to be dried, blower (12) for supplying air heated by heat radiator (23) to rotary tub (5), and heat-exchange air flow paths (22, 24) for circulating the air stayed in rotary tub (5) through heat radiator (23) via heat absorber (21). Fins striding over heat absorber (21) and heat radiator (23) allow integrating absorber (21) and radiator (23) into one body which can be thus placed within air-flow paths (22, 24). Heat-transfer reducing section (32) is formed on the fins between heat absorber (21) and heat radiator (23) for reducing the heat transfer via the fins between heat absorber (21) and heat radiator (23). The foregoing structure can prevent frost and ice produced on heat absorber (21) from growing, so that a compact cloth dryer excellent in drying performance is obtainable.
