Solid-liquid distribution detecting apparatus

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.
