Distillers Corn Oil Recovery

We Can Help You Increase Your Corn Oil Yield Today

Distillers corn oil is, by far, the most profitable coproduct in any dry grind corn ethanol plant. On average, most ethanol producers are only extracting about one-third of the available distillers’ corn oil (DCO). More troubling: That yield varies wildly, leaving behind between one-third and three-quarters of the DCO.

At current prices, just smoothing out DCO yield could translate to hundreds of thousands of dollars of revenue each month. With the right technology, it’s not unusual for a plant to add millions of dollars in annual revenue by merely improving DCO extraction (without detracting from your ethanol production or degrading the value of your DDGS as animal feed). We are eager to help get you there.

Increasing Your DCO Yields

Roughly 40 percent of the DCO produced in North America is extracted using Trucent technology and solutions. Over the past several years, Trucent has built a proprietary analytical method and platform to stabilize and maximize DCO extraction.

This extraction analysis platform is built on benchmarking studies tracking more than 40 ethanol plants, monitoring 250 DCO-related factors across thousands of samples. In the process, we isolated 50 key factors that help pinpoint the changes in chemistry and flow management needed to increase your DCO yield. As a result, we can fine-tune oil extraction to maximize a specific plant’s operation. Today, we can regularly extract DCO with between 75 percent and 95 percent efficiency.

Industrial Fluid Separation Three Stage Centrifuge

Some of these gains come back to equipment: We’ve modified our high-speed disc centrifuges and syrup conditioning system to more efficiently extract more corn oil while protecting downstream equipment. These systems are optimized to cope with the inherently unpredictable fluctuations in stillage solids content. They also integrate improved clean-in-place (CIP) procedures that mitigate fouling and clogging. Trucent Oil Tracker Programs include detailed weekly reports noting sample variations and recommending actions to improve oil recovery.


Guided by Process, Dedicated to Service

We embrace a process-oriented approach to corn oil extraction. This has meant spending decades investing in a team composed of more than centrifuge specialists and decanter technicians. We bring together people who understand equipment, people doing original and fundamental research in fluid separation, and people who understand the complex interdependence of ethanol, biodiesel, corn oil, and feedstock. Our team works with your team to deeply understand your production process, uncover the right intervention, determine the right technology, and match it to the proper application.

Every solution begins with a conversation. Contact us today to begin that conversation, or schedule a free, no-obligation on-site consultation. Let’s find a better way to maximize your distillers’ corn oil recovery.


Comprehensive Corn Oil Extraction Solutions & Services

Trucent provides comprehensive solutions to your corn oil and ethanol challenges. We don’t just sell and service equipment—a Trucent team can design an entirely new oil extraction solution for your process. We can install one piece of equipment or an entire team to manage all of your corn oil extraction needs. The goals remain the same: Consistently capturing the most DCO out of your ethanol production, every day.

Third COSS Module Adds $1.2M in DCO Annually


Adding a third Corn Oil Separation System (COSS-SL) module helps Midwestern ethanol producer generate $1.2M annually and decrease additive costs by $300K.


Within weeks, the third COSS installation and integration was compatible and produced 24% more DCO (limited by feed fat feed tag requirements). In addition, a 70% reduction in chemical usage was achieved.
