Title:
SOLID-LIQUID DISTRIBUTION DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/093406
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a solid-liquid distribution detection apparatus that detects a solid-liquid distribution in a solid-liquid separation column. A solid-liquid distribution detection apparatus (20) according to the present invention is for detecting a solid-liquid distribution of a content in a solid-liquid separation column (10) of a freeze concentration apparatus, and is provided with: a sound source (21) that emits a sound wave toward the column surface of the solid-liquid separation column (10); a measuring instrument (22) that measures a resonance waveform on the column surface; and an analysis device (24) that analyzes the resonance waveform measured by the measuring instrument (22), and determines the solid-liquid distribution state of the content in the solid-liquid separation column on the basis of the analysis result.
