ABSTRACT:
The present invention relates to an apparatus for processing materials, a process for mixing, finishing and de-volatizing polyamide to make 66 nylon and the 66 nylon made by this process. The apparatus comprises an agitator section having an outlet adjacent the bottom thereof; a transfer screw disposed adjacent the outlet of the agitator section; a spiral ribbon extending upwardly from the transfer screw; a ring disposed vertically above the spiral ribbon, at least one baffle disposed vertically above the spiral ribbon and connected to the ring and a wall-wiping spur connected to the ring. Preferably, the apparatus has two baffles--an upper one for pumping the material downwardly and a lower one for pumping the material upwardly. The diameter of each baffle is preferably about 80% of the diameter of the agitator section.
