Title:
紫外線によるエチレンガスの改質方法並びにその方法を実施するためのエチレンガスの改質装置及びその装置を用いた生鮮農産物の鮮度保持装置
Document Type and Number:
Japanese Patent JP4332107
Kind Code:
B2
Abstract:
To provide a method for irradiating ultra-violet rays a water retention member added with water droplets, generating OH radical in the water droplets and modifying ethylene gas into ethane and water through the OH radical. Water is supplied to the aeration water retention member 2a formed with a water retention surface capable of holding water in its particle shape in such a way that the water is held on it under particle shape to cause the water retention surface to be kept in a state where the water retention surface is wetted with water droplets. Then, ultra-violet rays S with a wavelength of 254 nm are irradiated water held on the water retention surface from a near distance within 10 mm while controlling a location near the ultra-violet rays emitting tube 3 to a temperature range of about 10 DEG C to 40 DEG C and then the OH radicals R are generated in the water droplets M with energy of irradiated ultra-violet rays. Further, gas containing ethylene gas is aerated the water retention surface holding water containing the OH radicals and the ethylene gas E contacted under an action of the OH radicals is modified into ethane (e) and water (w).
