Trucent - Model COSS-SL -Ethanol Corn Oil Centrifuge
Too many ethanol plants are extracting just a fraction of their available corn oil. We want to help you get more. So we’ve expanded our proprietary emulsion breaking chemistry, our process analytics, and our centrifuge offerings with that specific goal in mind: best-in-class DCO recovery and extraction.
Trucent’s COSS-SL is a centrifugal separator designed to achieve high-efficiency removal of corn oil from stillage or syrup. It produces high-centrifugal acceleration for the recovery of free corn oil without any negative side effects to the ethanol or DDG production process.
The syrup enters the centrifuge bowl and is distributed within a vertical disc stack, which increases the surface area of separation and, therefore, efficiency. The disc’s thickness, spacing, and angle; the location of the rising channels; and the number of discs in the COSS-SL disc stack were all designed specifically for DCO extraction.

With over 70 installations, Trucent’s COSS technology has proven its extraction efficiency and reliability. Building upon previous successes and our understanding of separation science, we have continued to evolve the COSS system to respond to changes in ethanol plant technology. The COSS-SL utilizes a skid-mounted disc stack centrifuge at its core and performs the industry’s most efficient mechanical extraction of DCO from stillage.
At Trucent, we’re dedicated to a process-oriented approach. We’ve spent decades building a team composed of more than equipment experts and engineers. We bring together people who understand centrifuges and separators and people who understand fluid separation at a fundamental level, in addition to being familiar with your fluids, processes, and industry. We’ll work together with you to match the right solution to your ethanol and corn oil centrifugation needs.
Every solution begins with a conversation. Contact us today to start a conversation or schedule a no-obligation on-site consultation.
