  • Evaluation method and evaluation device
    Patent number: 11154626
    Abstract: An evaluation device includes: a processing container that has an intake port and an exhaust port; a microorganism supply device that floats microorganisms in the air inside the processing container; a light source that irradiates the microorganisms floating in the air inside the processing container with ultraviolet rays while the intake port and the exhaust port are in a state of being closed; and a microorganism recovery device that is connected to the exhaust port. The microorganism recovery device discharges air that has a volume larger than the capacity of the inside of the processing container through the exhaust port while introducing air that does not contain microorganisms to be evaluated into the inside of the processing container through the intake port after the irradiation with the ultraviolet rays and recovers the microorganisms contained in the air that is discharged.
