MOR has recently introduced a new, innovative milling solution for corn based ethanol plants that promises to be a system beyond all others. The patent-pending MOR-Frac™ Plus+ Milling System combines the product purity and product yields of corn wet milling with the product quality (i.e., less degradation and exposure to chemicals) of dry milling, and with energy efficiency, environmental impact, and capital and operating costs much closer to those of dry milling.
How does it work?
The system begins by utilizing the best parts of the MOR-Frac™ Dry Milling System at the front of the process, and then uses short but effective wet milling steps to further refine and separate the products. The new system combines positive attributes of both dry and wet milling technology in an integrated system.
Features and Benefits
The MOR-Frac™ Plus+ Milling System truly stands in class by itself with the following features:
- Demonstrated fermentables loss below 2%
- Increased germ oil content - above 42%
- Compared to dry fractionation:
- High-value, food-grade market for germ
- Lower starch loss
- Near-zero sugar loss*

- Returns nutrients back to fermentation, requiring fewer additional nutrients
- No additional water use (water used is simply makeup water in slurry tank)
- Potential to recovery higher-value food-grade fiber
- Compared to “modified wet” fractionation:
- Higher quality germ
- Lower energy use
- Lower water use (same water saving benefits as dry fractionation)
- Lower capital requirement
Capturing the Value of Food-Grade Corn Oil
The MOR-Frac™ Plus+ system solves a major concern with dry fractionation systems - “what to do with the germ?” Dry fractionation systems often have to sell their lower quality germ to the animal feed market, getting a value less than conventional DDGS price, which defeats much of the purpose of a fractionation system.
MOR’s system produces germ that exceeds wet-milled germ specifications, allowing it to be sold to existing solvent extraction companies. MOR also provides off-take and marketing services for the germ product through their partner, Quality Technology International, Inc.
See the Co-Products section for more information on QTI’s germ marketing services.
Decreased Starch and Sugar Loss
The MOR-FracTM Plus+ system also recovers valuable starches and sugars for the ethanol process, thereby increasing yields and decreasing nutrient costs. Read more here about the importance of sugar loss and recovery.
