Abstract

An apparatus for measuring the particle size and dryness/wetness of a raw material according to one embodiment of the present invention may comprise: a visible-light illumination unit for irradiating visible light to a raw material being transferred; an infrared illumination unit for irradiating infrared light to the raw material; a camera for acquiring an image of the raw material irradiated with visible light and infrared light, in a direction different from the irradiation direction of the visible-light illumination unit; and an image processing unit for generating particle size information and dryness/wetness information of the raw material by analyzing the acquired image.
