A water-free protein enhancement process for distillers grains

Dry Distillers Grains (DDG) and Dry Distillers Grains and Solubles (DDGS) are a nutrient-rich co-product of the ethanol production process. Both are also a valuable food source for the livestock industry, especially beef cattle. And while both have been used as a supplemental feed for several decades, they are becoming a more prominent commodity for a couple of reasons:

    • First, as ethanol production increases, more and more DDG and DDGS is becoming available, making it economical for farmers to buy to use as a supplement with whole grains such as corn for feed.
    • Second, it is higher source of protein for cattle than raw-material counterparts. Using corn as an example, two-thirds of raw corn is made up of starch, which is why it is a perfect source for the dry fermentation process that eventually produces ethanol. The co-product also has a relatively high fat content, which is perfect for adding bulk to cattle naturally, without steroids.

So, it’s a win/win situation for both sides. But as previously mentioned, as the supply of DDG and DDGS increases, the unit price may drop due to greater competition from various distillation sources. The good news is that ST Equipment & Technology (STET) is helping producers reap better profits from the same source material by extracting more of the valuable protein material away from the fiber content by using a revolutionary and proprietary triboelectrostatic separation process.

The benefits of the process don’t stop there. No water or chemicals are needed to produce a premium-grade DDGS product, which means no fresh water source is necessary and no holding ponds are needed to deactivate harmful chemicals. In addition, the STET separator can operate continuously at a high rate (approximately 15 tons of input per hour), while consuming very little energy in the process. So, it’s environmentally friendly, one heck of a workhorse, and there are no additional overhead costs needed to produce a premium product and more of it from your current feed streams.
