Title:
HIGH DEHYDRATION TYPE ROTATION PRESSURIZATION DEHYDRATOR
Document Type and Number:
WIPO Patent Application WO/2005/105263
Kind Code:
A1
Abstract:
A rotation pressurization dehydrator adapted to locally increase the compressive force on moving dehydrated cake so as to efficiently reduce the liquid content of its region for which dehydration has not been sufficient by a conventional rotation pressurization dehydrator, whereby in discharged, dehydrated cake, the difference in liquid content among regions is made small. In a rotation pressurization dehydrator (3) which, as a raw material advances in an annular filter chamber (41) formed around a rotary shaft (32), gradually applies a pressure to the material to change the liquid material into cake, thereby dehydrating the material, projections (51) are disposed on the inner peripheral surface (34c) of an outer ring spacer (34) so as to further reduce the liquid content of the dehydrated cake.
