Yayinda iyakoki akan kayayyakin ethanol suke ƙara ƙarfi ko ɓacewa, yawancin masu samar da ethanol sun zaɓi mayar da hankali ga ƙimar kirkirar abubuwa daga kayan masarufi. Dry distillers hatsi tare da solubles (DDGS) have long been an undervalued coproduct. Amma a 28 to 32 kashi furotin, ya ƙunshi furotin da yawa sosai don gane cikakken kimar sa, yayin da a lokaci guda suna yin karancin furotin da za'a iya amfani dasu a cikin manyan abubuwan da za'a iya amfani dasu don ciyar da abinci mai narkewa kamar kifin kifi, 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, an ayyana shi azaman ciyar da dabba da ya yi daidai da abubuwan da ake buƙata ta abinci. Sauran dama, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, ƙarfafa wannan yanayin kasuwa.
Bushe, Wet, and Electrostatics kwanan nan, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: waɗanda aka haɗa su tare da aikin samar da ethanol kuma suna aiki a kan rafuka masu gudana. 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, rarrabuwa girman yanki kamar tacewa ko nunawa, da kuma rarrabuwa mai yawa kamar rabuwa da mahaukata don raba yisti daga fiber tsire-tsire. These systems may be before or after the fermentation stage. Duk da haka, 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.
Da bambanci, dry processing methods are independent of the ethanol production process kuma a maimakon haka suyi aiki akan rafin DDGS kai tsaye. Irin waɗannan tsarin sau da yawa suna amfani da niƙa, air classification, or dry sieving. Hanya ɗaya ta sabon labari tana amfani da rabuwa ta lantarki don samar da furotin mai yawan DDGS ta cire fiber a cikin cikakken ruwa, tsarin ƙarshen-baya wanda ke zaman kansa ga tsarin samar da ethanol.
Electrostatics wani lamari ne wanda kusan kowa ya sami kansa a rayuwar yau da kullun, amma kaɗan sun ci karo a cikin yanayin masana'antu. It is the effect of rubbing a balloon on a person’s hair. Yayinda balan-balan din roba take haduwa da gashin mutum, yana cire wutar lantarki daga cikin gashi. Wannan saboda roba da yawancin polymer suna da ƙarfin lantarki (dangantaka ga electrons). An bar balan-balan ɗin tare da caji mara kyau, bayan tara ƙarin electron, kuma batun batun yana da caji mai kyau. Electrical charges repel each other, don haka gashin batun yana tsaye a ƙarshe a ƙoƙarin ƙara girman tazara tsakanin wasu tufafin da aka yiwa daɗi da kyau.
Game da 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. Rabin electrostatic has been used by selected industries for many years. In mineral processing and recycling applications, electrostatic rabuwa ya kasance a kasuwanci amfani ga akalla 50 shekaru. Electrostatic rabuwa da shuka-tushen kayan da aka bincika for kan 140 shekaru, tare da patent na farko don raba electrostatic na alkama garin middlings da aka shigar da wuri-wuri 1880.
kwanan nan, sarrafa wutar lantarki ya sami kulawa da yawa a matsayin hanyar tattara sunadaran shuka. Wannan ci gaban da ya kara a baya 10 to 20 shekaru, tare da yawancin jami'o'in bincike a Turai da Amurka. da ake ji electrostatic rabuwa dabaru zuwa m iri-iri na kayan ciki har da DDGS, oilseed abinci, fis da ƙwayoyin cuta. Daga wannan bincike, Tabbatacce ne, cewa electrostatic hanyoyin da damar samar da sabon, mafi girman darajar sinadaran furotin da samfuran, da bayar da madadin hanyoyin sarrafa ruwa.
Hanyoyin rabuwa da lantarki suna da fa'ida akan hanyoyin rabuwa, gami da tsada da sassaucin aiki daga tsarin samar da ethanol. Hanyoyin rabuwa na Electrostatic suma suna ba da fa'idar buƙatar babu kemikal ko ruwa. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. Kuma rabuwa ta lantarki yana da sauki, a cikin hakan ba ya canza aikin furotin na asali.
ST Boats & Technology da aka amfani da electrostatic rabuwa a masana'antu aikace-aikace tun 1995. It is used to process fly ash from coal power plants. Fiye 20 miliyan tan na samfurin gardama ash aka sarrafa ta STET separators shigar a Amurka. kadai.
Kodayake ga wasu, repurposing technology to process fly ash (wani gilashin aluminosilicate mai gilashi wanda ya rage daga ƙona kwal don ƙarfi) don tattara furotin shuka daga DDGS na iya zama baƙon abu. In truth, kasuwar DDGS da kasuwar kuda sun ba da kamanceceniya mai ban mamaki. Don masu farawa, 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. masana'antar ethanol a 2019. Ta hanyar kwatantawa, Amurka. masana'antar wutar-kwal ta samar da kusa 35 miliyan metric tan na ƙuda tashi a 2017. Ana sayar da samfuran biyu a ƙananan ribato. 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. Tashi masu maye gurbin suminti, the most expensive component in ready-mix concrete. DDGS yayi gasa tare da sauran tushen sunadarai kamar su waken soya, canola, and sunflower meal, da sauransu.
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 yayi irin wannan juyin, 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.
Daga qarshe, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, ciki har da distillers hatsi, zai ci gaba. Fasahar sarrafa abubuwa za ta ci gaba da zama mai mahimmanci don haɓaka aikin fasaha na haɓakar furotin. Har ila yau,, shaping their value-creation potential for the ethanol industry.
