Maaddaama dariiqyada ku yaal alaabada ethanol ay adkeynayaan ama baaba'ayaan, inbadan oo soosaarayaasha ethanol waxay doortaan inay diirada saaraan abuuritaanka qiimaha laga soo saaro soosaarka. Qalalan mudalacayaasha qalalan oo leh milanno (DDGS) have long been an undervalued coproduct. Laakiin at 28 si ay u 32 borotiinka boqolkiiba, Waxay ka kooban tahay borotiin aad u badan si ay u xaqiijiso qiimaheeda buuxa sida quudinta, halka isla mar ahaantaana ay ku yar tahay borotiinka in loo adeegsado saamiyada beddelka sare ee loogu talagalay quudinta monogastric-ka sida aquaculture, 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, Waxaa lagu qeexay bixinta xayawaan siiya si ku habboon buuxinta baahiyaha nafaqada. Fursadaha kale, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, xoojiya isbeddelladan suuqa.
Qalalan, Wet, and Electrostatics Recently, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: kuwa ku dhex jira habka wax soo saarka ethanol kuna shaqeeya durdurrada socodka qoyan. 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, kala soocida cabirka walxaha sida sifeynta ama baaritaanka, iyo cufnaanta kala soocida sida kala soocida duufaanka si loo kala saaro khamiirka iyo fiber-ka dhirta. These systems may be before or after the fermentation stage. Si kastaba ha ahaatee, 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.
Taas bedelkeeda, dry processing methods are independent of the ethanol production process oo taa badalkeeda ku shaqeeya durdurka DDGS si toos ah. Nidaamyada noocan oo kale ah waxay badanaa isticmaalaan shiidi, air classification, or dry sieving. Mid ka mid ah habka cusubi wuxuu adeegsadaa kala-soocidda korantada si loo abuuro borotiin sare oo leh DDGS adoo ka saaraya fiber-ka gabi ahaanba biyo-la'aan, geedi socodka gadaal-dhamaadka oo ka madax banaan hanaanka wax soo saarka ethanol.
Electrostatics waa dhacdo in ku dhow qof walba soo maray gacanta koowaad ee nolol maalmeedka, laakiin in yar baa la kulantay goob warshadeed. It is the effect of rubbing a balloon on a person’s hair. Maaddaama buufinka cinjirka ahi uu taabanayo timaha dadka, wuxuu ka saaraa timo elektaroono. Tani waa sababta oo ah cinjirka iyo polymer-ka badankood waxay leeyihiin koronto sare (isku xirnaanta elektaroonigga). Buufinka waxaa looga tagayaa lacag saafi ah oo saafi ah, isagoo ururiyey korantada dheeraadka ah, iyo mawduuca timuhu wuxuu leeyahay kharash wanaagsan. Electrical charges repel each other, markaa mawduuca timuhu wuxuu istaagayaa dhamaadka iyadoo la isku dayayo in la weyneeyo masaafada u dhexeysa qaybaha kale ee timaha ee sida wanaagsan u eedeeyay.
Xaga 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. Kala saarista electrostatic has been used by selected industries for many years. In mineral processing and recycling applications, kala-soocidda korantada ee loo yaqaan 'electrostatic' ayaa ugu yaraan loo adeegsaday ganacsi 50 sano. Kala-soocidda korantada ee qalabka dhirta ku saleysan ayaa la baaray in ka badan 140 sano, oo leh rukhsaddii ugu horreysay ee kala-soocidda electrostatic ee middlings bur burka oo la xareeyay sida ugu dhakhsaha badan 1880.
Recently, processing electrostatic ayaa helay heshiis weyn oo fiiro gaar ah sida habka in ay xoogga saaraan borotiinka dhirta. horumarinta Tani ayaa la dedejiyey ee la soo dhaafay 10 si ay u 20 sano, oo leh jaamacado badan oo cilmi baaris ah oo ku yaal Yurub iyo Mareykanka. codsanaya farsamooyinka kala-electrostatic kala nooc oo kala duwan oo ay ka mid yihiin DDGS, cuntada oilseed, iyo digir iyo garaaca wadnaha. From cilmi, waxaa iska cad in hababka electrostatic leeyihiin awood u leh in ay curiyaan cusub, maaddooyinka iyo alaabada borotiinka ee qiimaha sare leh, waxayna ku siinayaan bedel hababka wax soo saarka qoyan.
Hababka kala-soocidda electrostatic waxay bixiyaan faa'iidooyin ka badan hababka kala-soocidda qoyan, oo ay ku jiraan kharashka iyo dabacsanaanta hawlgalka ee habka wax soo saarka ethanol. Hababka kala-soocidda Electrostatic sidoo kale waxay bixiyaan faa'iidada aan u baahnayn kiimiko ama biyo. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. Kala soocista electrostatic waa mid fudud, taasna ma beddeleyso waxqabadka borotiinka asalka ah.
ST Qalabka & Teknolojiyaddu waxay u adeegsaneysaa kala-soocidda korantada ee codsiyada warshadaha tan iyo 1995. It is used to process fly ash from coal power plants. In ka badan 20 milyan oo tan oo ash ash dhoob ah ay ka baaraandegeen by STET kala lagu rakibay Maraykanka. kaligaa.
In kastoo qaarkood, repurposing technology to process fly ash (macdan aluminosilicate ah oo dhalo ah oo ka hartay gubida dhuxul si awood loogu helo) si loo xoojiyo borotiinka dhirta ee ka timid DDGS waxay umuuqan kartaa wax lala yaabo. In truth, suuqa DDGS iyo suuqa dambaska ayaa wadaaga qadar layaab leh oo ay iskaga mid yihiin. Kuwa bilowga ah, 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. warshadaha ethanol ee 2019. Isbarbar dhig, Mareykanka. warshadaha dhuxusha-laga soo saaro 35 milyan oo metrik ton oo dambas ah 2017. Labada sheyba waxaa lagu iibiyaa qadar yar. 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. Bedelka dambaska sibidhka, the most expensive component in ready-mix concrete. DDGS waxay la tartantaa ilaha kale ee borotiinka sida soy, canola, and sunflower meal, iyo kuwo kale.
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 waxay sameysay horumar la mid ah, 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.
Ugu dambeyntii, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, oo ay ku jiraan miraha masaxa, wuu socon doonaa. Farsamaynta farsamooyinka ayaa sii wadi doonta inay muhiim u tahay kordhinta waxqabadka farsamada ee soosaarka borotiinka. Sidoo kale, shaping their value-creation potential for the ethanol industry.
Teknoolojiyadaani waxay u baahan doonaan inay muujiyaan waxqabad joogto ah, isku halaynta sare, low cost, and rapid return of capital to end users. Nala soo xiriir now for more information.
