DEHYDRATOR

PURPOSE:To improve a capacity of dehydrating treatment and to make an equipment small in size by adding a simple construction, by supplying flocculants to treating matters to be supplied to a gravity dehydrating part and supplying moisture absorbing agent to the treating matters to be supplied to a forcedly dehydrating part. CONSTITUTION:Dehydrating performance in a gravity dehydrating part A is improved by providing a supplying device 11 of flocculant to a supplying tank 9 of treating matters. A receiving tank 12 for the treating matters treated previously by gravity dehydration is provided to the under side of a tension roller 4 at the end side of said part A to provide a supplying device 13 of moisture absorbing agent and a device 14 for kneading the agent and the treating matters after dehydration, and then the matters after gravity dehydration is fed to a forcedly dehydrating part B in a state of the treating matters to have small water content and low flowability. As a result, significant improvements of the capacity of dehydrating treatment and a compact dehydrating equipment are obtained by adding an extremely simple construction.
