Title:
STEAM STRIPPING DEVICE AND STEAM-STRIPPING FINISHING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/080969
Kind Code:
A1
Abstract:
A steam stripping device that is capable of operating for long periods of time and can prevent crumb from getting stuck to the inside walls of a crumbing tank, piping from getting blocked by reaggregated large-diameter crumb, a screen from getting clogged by small-diameter crumb, and an extruder from slipping. The aforementioned crumbing tank is provided with the following: an agitation shaft; an agitation blade that has a knife blade; and a baffle plate on an inside wall. The cross-section of the baffle plate in the transverse direction of the cylindrical crumbing tank has an upstream side surface and a downstream side surface with respect to the flow of a fluid, and said side surfaces coincide to form a vertex of a substantially triangular cross-section. In the cross-section of the baffle plate in the transverse direction of the cylindrical crumbing tank, the line segment representing the upstream side surface forms an angle of 30-75° with a line segment connecting the center of the agitation shaft to the abovementioned vertex, as does the line segment representing the downstream side surface.
