Abstract: It is an object of the present invention is to obtain a solid-liquid distribution detecting apparatus that detects solid-liquid distribution in a solid-liquid separation column. A solid-liquid distribution detecting apparatus (20) of the present invention detects solid-liquid distribution of a content in a solid-liquid separation column (10) of a freeze concentration device and includes a sound source (21) that emits a sound wave to the column surface of the solid-liquid separation column (10), a measuring device (22) that measures a resonance waveform on the surface of the column, and an analysis device (24) that analyzes the resonance waveform measured by the measuring device (22) and determines a solid-liquid distribution state of the content in the solid-liquid separation column based on the analysis result.

Abstract: A method and a device, for detecting a solid-liquid distribution in a solid-liquid separation column of a freeze concentration device, that are used when a freeze concentration method is performed is suggested. The device for detecting the solid-liquid distribution in the solid-liquid separation column of a solid-liquid separation device includes a light irradiation means for irradiating the inside of the solid-liquid separation column of the freeze concentration device with visible light, a photographing means for picking up an image of the inside of the solid-liquid separation column irradiated with the visible light by the light irradiation means, a movement means for moving the photographing means in an up-and-down direction of the solid-liquid separation column, an image analysis means for analyzing a data piece of an image picked up by the photographing means and a determination means for determining a solid-liquid distribution state in the solid-liquid separation column based on a result of an analysis made by the image analysis means.
