A possible rapid method of determining the moisture content of high‐moisture grain

摘要

AbstractA linear relationship was shown to exist between the moisture content of barley and of tick beans and the temperature rise obtained when a quantity of concentrated sulphuric acid was added to the grain. This relationship can be used to determine the moisture content of grain, particularly at the higher moisture levels which are often outside the upper limit of many existing rapid methods of moisture measurement.The ‘acid’ method is reasonably rapid, taking about 15 minutes, and gives a reproducibility of approximately 1.0 moisture content. If the initial temperature of the grain differs widely from the calibration temperature, a temperature correction must be appl
