  • Patent number: 12313544
    Abstract: A method and device for identifying the washing quality of a feather material are applied to a feather material washing apparatus and essentially entail: a sampling unit that takes an appropriate amount of the water discharged from the feather material washing apparatus as a water sample, an impurity removing module that removes feather fiber and impurities that may compromise inspection accuracy, and a laser sensing device that senses, while the water sample is static, a transparency value of a portion of the water sample that extends across a predetermined distance, in order to identify the washing quality of a washed feather material. The method and device for identifying the washing quality of a feather material exercise intelligent judgment to enable a consistent standard, to ensure the efficiency and quality of a feather material washing procedure, and to reduce the associated costs.
