Gbẹ, Wet, and Electrostatics laipe, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: awọn ti o ṣepọ pẹlu ilana iṣelọpọ ethanol ati ṣiṣẹ lori awọn ṣiṣan ilana tutu. And those that occur after the ethanol production process and operate on dry process streams. The wet technologies often utilize combination of separation methods that rely on particle size modification such as grinding, ipin ipin patiku gẹgẹ bi iyọ tabi ibojuwo, ati ipinya iwuwo gẹgẹbi ipinya cyclone lati ya iwukara kuro ni okun ọgbin. These systems may be before or after the fermentation stage. sibẹsibẹ, the separation of protein from fiber occurs before distillers grains are dried. These wet systems are integrated into ethanol process and therefore operate simultaneously with ethanol plant.
Nipa itansan, dry processing methods are independent of the ethanol production process ati dipo ṣiṣẹ lori ṣiṣan DDGS taara. Iru awọn ọna bẹẹ nigbagbogbo lo lilọ, air classification, or dry sieving.

Ninu ọran ti DDGS, protein and fiber acquire opposite electrical charges upon contact with each other, allowing them to be separated from each other in a high-strength electric field.
Electrostatics is not a new phenomenon and has a large number of real-world and industrial applications. Iyapa Electrostatic has been used by selected industries for many years. In mineral processing and recycling applications, ipinya electrostatic ti wa ni lilo iṣowo fun o kere ju 50 ọdun.

In truth, ọjà DDGS ati ọja eeru eṣinṣin pin iye iyalẹnu ti awọn afijq.

Their value is highly dependent on processing and transporting large volumes at low costs.
Both DDGS and fly ash ultimately derive their value from displacing other higher-cost materials. Fidi awọn aropo eeru fun simenti, the most expensive component in ready-mix concrete. DDGS dije pẹlu awọn orisun amuaradagba miiran bii soy, canola, and sunflower meal, lara awon nkan miran.
DDGS and fly ash have to make the journey from low-value waste stream to value-added coproduct. Fly ash was long considered a waste product. To be landfilled until low-cost technologies enabled it to be recycled as a value-added component in ready-mix concrete. DDGS ti ṣe iru itankalẹ kan, from being considered a low-value feed material to becoming a manufactured feed ingredient. It is globally exported and increasingly sold under trademarked names with an emphasis on quality and consistency.
