Current practice in designing bottom-entering fermentor drives.
Top entering drives have become almost traditional for fermentor applications, however bottom entering drives have distinct features that merit consideration. The principal advantages of bottom drives are delineated and design criteria discussed. Illustrations based on experience with several hundred fermentors ranging in power from fractional to 100 HP and in scale from 10 to 30,000 gallons are presented. Specific areas dealt with include configuration, alignment, seals, and shaft design.
