Ka oke dị na ethanol na ngwaahịa sie ike ma ọ bụ pụọ n'anya, ọtụtụ ndị na-emepụta ethanol na-ahọrọ ilekwasị anya na okike bara uru site na mkpụrụ akwụkwọ. Mịrị distillers grains na solubles (DDGS) have long been an undervalued coproduct. Ma na 28 ka 32 pasent protein, O nwere protein bara ụba iji ghọta uru ya bara ụba, ebe n'otu oge dị ala na protein a ga-eji ya na nnukwu ihe eji eme ihe maka oke nri anụ na - eme nri ka ahịhịa., swine, and poultry.
This is a common challenge across the animal feed industry and represents a huge opportunity in the field of precision animal nutrition, akọwapụtara dị ka inye ụmụ anụmanụ nri ga-ezuru ya nri chọrọ ya. Ohere ndị ọzọ, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, sikwuo ike ahịa a.
Akọrọ, Wet, and Electrostatics na nso nso, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: ndị ahụ ejikọtara na usoro mmepụta nke ethanol ma rụọ ọrụ na mmiri iyi mmiri. 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, urughuru nkewa oke dị ka filtration ma ọ bụ echetakwa, na njupụta nkewa dị ka nkewa cyclone iji kewaa yist na eriri osisi. These systems may be before or after the fermentation stage. Otú ọ dị, 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.
Site na iche, dry processing methods are independent of the ethanol production process ma rụọ ọrụ na mmiri DDGS ozugbo. Dị otú ahụ na usoro mgbe ahu nagide-egweri, air classification, or dry sieving. Otu akwụkwọ ọhụụ na-eji nkewa nke electrostatic iji mepụta DDGS protein dị elu site na iwepu eriri na mmiri na-enweghị mmiri, Usoro njedebe-azụ nke na-adabereghị na usoro mmepụta ethanol.
Electrostatics bụ ihe ọhụụ na ọ fọrọ nke nta ka onye ọ bụla nwee ahụmahụ mbụ na ndụ kwa ụbọchị, ma ole na ole ezutewo na ụlọ ọrụ mmepụta ihe. It is the effect of rubbing a balloon on a person’s hair. Dika balloon roba na-abanye na ntutu mmadụ, ọ na-ewepu elektrọn na ntutu. Nke a bụ n'ihi na roba na ọtụtụ polymer nwere nnukwu electronegativity (mmekọrita maka elektrọn). A na-ahapụ balloon ahụ na ụgwọ na-adịghị mma, ọ chịkọbaala elektrọn ndị ọzọ, na ntutu isi nke isiokwu ahụ nwere ụgwọ dị mma. Electrical charges repel each other, ya mere, ntutu isi nke isiokwu ahụ na-eguzo na njedebe iji mee ka ebe dị anya n'etiti eriri ntutu ndị ọzọ ebubo nke ọma.
N'ihe banyere 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. Electrostatic nkewa has been used by selected industries for many years. In mineral processing and recycling applications, electrostatic nkewa anọwo na azụmahịa were dịkarịa ala 50 afọ. Electrostatic nkewa nke osisi dabeere ihe e nyochara ihe karịrị 140 afọ, na nke mbụ patent maka electrostatic nkewa nke ọka wit ntụ ọka middlings gbara akwụkwọ dị ka n'oge dị ka 1880.
na nso nso, nhazi oru electrostatic anatawo otutu ihe nlebara anya dika usoro iji tinye uche na ndi na-edozi protein. Na mmepe ya ngwa ngwa na ihe ndị gara aga 10 ka 20 afọ, na ọtụtụ mahadum nyocha na Europe na US. itinye electrostatic nkewa usoro na a dịgasị iche iche nke ihe gụnyere DDGS, oilseed nri, na agwa na usu protein. Site na nke a research, oputara ihe na electrostatic ụzọ nwere ike n'ịwa ọhụrụ, elu-uru osisi protein Efrata na ngwaahịa, ma nye uzo ozo maka usoro nhazi mmiri.
Ofzọ nke electrostatic nkewa na-enye uru n'elu mmiri nkewa ụzọ, gụnyere mgbanwe ego na arụmọrụ site na usoro mmepụta ethanol. Electrostatic nkewa ụzọ na-enyekwa uru nke na-achọ ọ dịghị Chemicals ma ọ bụ mmiri. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. Na nkewa electrostatic dị nwayọọ, na ọ naghị agbanwe ọrụ nke protein ala nna ya.
ST Equipment & Technology a na-eji electrostatic nkewa na ulo oru ngwa ebe 1995. It is used to process fly ash from coal power plants. N'ime 20 nde tọn ngwaahịa ada uyi e esichara site STET separators arụnyere na U.S.. naanị.
Ọ bụ ezie na ụfọdụ, repurposing technology to process fly ash (a enyo aluminosilicate ịnweta fọdụrụ site na-ere ọkụ ọkụ maka ike) itinye uche na protein nke osisi site na DDGS nwere ike iyi ihe iju. In truth, ahịa DDGS na ahịa uyi na-ekerịta oke ihe ijuanya. Maka ndị mbido, both products are generated in large volumes in the U.S. With an estimated 36 million metric tons of distillers grains produced by the U.S. ụlọ ọrụ ethanol na 2019. Site n'iji ya tụnyere, ndị US. ụlọ ọrụ na-ere ọkụ na-emepụta gburugburu 35 nde metrik tọn ada uyi na 2017. A na-ere ngwaahịa abụọ na oke ala. 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. Ofufe ash nọchiri nke ciment, the most expensive component in ready-mix concrete. DDGS soro na protein ndi ozo di ka soy, canola, and sunflower meal, n'etiti ndị ọzọ.
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 mekwara ụdị ihe ahụ, 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.
Mee elu mee ala, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, tinyere distillers grains, ga-aga n'ihu. Teknụzụ na-arụ ọrụ ga-anọgide na-adị oke mkpa iji bulie arụmọrụ teknụzụ nke protein coproducts. Ọzọkwa, shaping their value-creation potential for the ethanol industry.
