| | | This graph shows results of measurement on coffee beans. Moisture content rate curve (red) does not stabilize into a planarized line. Derivative curve (green) increases and decreases after commencement of heating, re-increasing when heated above 180c. With such samples, continuous vaporization of other ingredients or carbonization is assumed to follow water vaporization. Such samples are not suitable for measurement with heat and dry method moisture analyzer. However, it is possible to measure and evaluate moisture content of such samples by measuring under same conditions (sample quantity, heating temperature, measurement termination condition), with previously set heating temperature and measurement termination condition (terminates measurement when moisture loss value is less than certain conditions). Meanwhile, carbonization of sample surface could be avoided by placing a glass fiber sheet on top of the sample, which enables heating under high temperature, therefore shortening measurement time and improving measurement accuracy. Such samples include coffee beans and green tea. | | |
