Abstract:
1. A device for the continuous degassing and production of polymeric pre-condensates to produce a higher ratio of surface area to volume of the product during processing, comprising: a heated enclosure; a plurality of modules stacked one above the other in said enclosure, each said module having a base; an inlet of vapor through said enclosure to the uppermost module of said plurality of modules in which said vapors are collected; at least one conduit in the base of each module to provide vapor flow communication to the module below it with the conduit at the base of the lowest module in the stack providing an outlet; wherein at least one said module intermediate said uppermost module and said lowest module provides space for expansion of the vapor flowing through said at least one conduit, the base of each said module of said plurality of modules is concave, and each said concave base starts from a flat peripheral edge portion extending from the interior of said enclosure.
