Distillers corn oil(DCO)/Crude Corn Oil separation system
The Ethanol/Distillery industry depends more than ever on their coproducts. DDGS (distiller’s dried grains with solubles) are essential, but what can make or break an ethanol plant is their corn oil, vital both as feedstock for biodiesel production and as a supplement to animal feed. DCO unit provides an additional revenue stream for grain-based distilleries with annual revenues in the range of 10Cr to 75Cr depending on plant capacity!
- Thick syrup, collected from concentrating thin slope in evaporation section, will be fed to static mixer where de-emulsifier will be mixed in required proportion.
- The syrup will be heated by using low pressure steam and then fed to tri-canter.
- This mixture will feed to the tri-canter, where the crude oil separation from thick syrup will be done.
- Two more streams will be separated from tri-canter - sludge and thick syrup, after removal of oil. Both these streams will be recycled back to the wet cake for the further drying in DDGS dryer.
- The crude oil separated from tri-canter will be further cooled down to normal temperature and stored in crude oil live storage tank & transferred to crude oil storage tank for issue purpose.
- DDGS quality improves as fat % gets reduced, protein % (weight/weight) improves thereby leading to a higher rate per kg.
Key points for distilleries!
- Corn oil recovery around 12-23 kg/ton of corn depending on grain composition
- Purity guarantee > 97 %
- Area requirement: broadly 20 mt x 20 mt
- Helps improve DDGS quality due to lesser fats and increased proteins % (weight/weight)
- Helps improve profit margins for the distillery by adding a new revenue stream
- Minimal capex investment and quick installation(can be designed as a skid-based system)
- Quick payback on capex investment
- End uses: For production of biodiesel, Mixing in Animal feed - Not fit for human consumption
