METHOD FOR TORREFACTION WITH HYPERSPECTRAL ANALYSIS OF THE TORREFIED MATERIAL DURING OR AFTER TORREFACTION

摘要

The invention relates to a method for on-site analysis of at least one quality parameter of a material in or from a torrefaction process. In said method, a NIR-camera is used to generate a data set which is processed in a computer using a multivariate statistical method.The invention also relates to a method for online control of the torrefaction process. In said method the absorbance of the torrefied material is analyzed by a NIR-camera to generate a data set which is processed in a computer using a multivariate statistical method.
