  • Patent number: 9518749
    Abstract: Provided is a forced evaporative humidifier using nano-vapor, which includes: a housing having an exhaust port formed in an upper surface thereof and a suction port formed at one side of a front surface thereof; a water tank located below the suction port to store water; an injection unit having an injection nozzle located above the suction port, a pump for pulling up the water in the water tank to the injection nozzle, and a transfer tube for transferring the water pulled by the pump; a blowing fan located above the injection nozzle to carry air toward the exhaust port of the housing; a humidifying unit located below the injection nozzle so that films, each having a body surface formed to allow the water injected from the injection nozzle to flow and a plurality of tube-type spacers protruding on the body surface, are stacked in a lateral direction therein; and an eliminator located between the blowing fan and the injection nozzle to prevent water drops included in a humid air humidified by the humidifying u

  • Patent number: 9016564
    Abstract: A product quality monitoring system includes: an RFID tag which is attached to a first packing container in which a product is packed, and transmits atmospheric history information and an identifier for a product distribution history; a QR code which is attached to a second packing container and stores the identifier and address information of a product quality predicting server; a product distribution history DB which stores the atmospheric history information and the identifier which are received from the RFID tag; a user terminal which connects with the product quality predicting server corresponding to the address information stored in the captured QR code, and requests a quality index of the product; and the product quality predicting server which calculates the quality index of the product or a time when the product has a specific quality index, from the atmospheric history information.
