Title: Innovations by Stephen D Allen
Introduction
Stephen D Allen is a notable inventor based in Eagle, ID (US), recognized for his contributions to the field of filtration technology. With a total of 13 patents to his name, Allen has made significant advancements in methods for separating solids from liquids, particularly in the context of ethanol fermentation.
Latest Patents
Among his latest innovations are two key patents related to rotary drum screen systems for thin stillage filtration. The first patent describes a rotating drum screen method that effectively separates solids from thin stillage obtained during ethanol fermentation. This method involves chemically treating the thin stillage with an anionic polymer to form stable particles, which are then introduced into a rotating drum screen system. The drum screen features a filter that retains solids while allowing liquid effluent to be discharged. The retained solids can be removed through a solid discharge end, enhancing the efficiency of the filtration process.
The second patent outlines a similar rotary drum screen system designed for separating solids from an influent material stream. This system includes a housing with an influent inlet and a solid discharge end, where a hollow portion of the drum screen receives the influent. The filter screen retains solids, producing a liquid effluent that is discharged from the outer surface of the drum screen. A head box within the drum directs the influent stream against the screen, optimizing the separation process.
