METHOD AND ARRANGEMENT FOR DETERMINING THE MOISTURE CONTENT OF WOOD CHIPS

摘要

The invention relates to a method and arrangement for measuring the moisture content of a flow of wood chips (2), through which collimated gamma radiatio n is directed (4) attenuation of which in the flow of wood chips (2) is measured. The flow of wood chips (2) is shaped according to the invention by transporting it on a through-shaped conveyor (1) in such a way that the leng th of a ray can be determined. The moisture content can be calculated (8) on th e basis of the proportion of gamma radiation passing through the flow of wood chips (2) and the flow's thickness, as well as on the basis of the previousl y determined air content of the flow of wood chips (2).
