Method of measuring moisture content of lignocellulosic biomass and sample compressor for measuring same

Abstract

Disclosed are a method of measuring moisture content of lignocellulosic biomass and sample compressor for measuring the same. The method of measuring the moisture content of lignocellulosic biomass comprises: (a) supplying a sample containing a lignocellulosic biomass; (b) acquiring the near-infrared spectrum of the sample; (c) mathematical preprocessing of the near-infrared spectrum; (d) Regression analysis (PLSR) of the mathematically pretreated near-infrared line spectrum by partial least squares method to construct a moisture content prediction model; and (e) obtaining the moisture content of the sample using the moisture content prediction model. According to the present disclosure, there is no data variation according to the density of the sample, the amount of the sample is not reduced because there is no sample collection for density measurement, and it is non-destructive and has the effect of quickly measuring the moisture content.
