| 摘要 |
The invention relates generally to an improved system for treating material proceeding continuously through a processing barrel B having at least twin interconnected cylinders. Rotating parallel mixer shafts 10a, coaxially mounted in the cylinders, have radially interwiping screw or paddle elements between a material charging inlet O and a material discharging outlet which are configured to wipe the cylinders. Sets of paddle elements 42, 43 each of which includes a cylinder blocking paddle 42, are provided on the shafts at a flow control station U between the inlet and outlet, and a movable flow-controlling saddle or valve element V is mounted with relation to the cylinder blocking paddle sets in a position such that it can be moved from an opened position to a position to restrict or block flow past the sets of paddle elements. There is a degassing vent 100 downstream of the location where the saddle or valve element V begins to back up the flow of material and the saddle or valve element V directs the flow away from the vent 100. <IMAGE>
