Monga m'mphepete mwazinthu zamagetsi zimalimbitsa kapena kutha, opanga ambiri amtundu wa ethanol amasankha kuyang'ana kwambiri pakupanga kwamtengo kuchokera kumaopanga. Zouma zoumba mbewu ndi zosungunulira (DDGS) have long been an undervalued coproduct. Koma pa 28 kuti 32 peresenti ya mapuloteni, ili ndi mapuloteni ochulukirapo kuti azindikire phindu lake lonse ngati chakudya chokocha, nthawi yomweyo kukhala yotsika kwambiri m'mapuloteni kuti asagwiritsidwe ntchito kwambiri m'malo olimapo ochepa ngati chakudya cham'madzi, 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, Kutanthauziridwa kuti kupatsa nyama chakudya chomwe chimakwaniritsa zofunikira pauperewu. Mwayi wina, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, limbikitsani msika uwu.
Youma, Wet, and Electrostatics posachedwapa, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: zomwe zimaphatikizidwa ndikupanga ethanol ndikugwira ntchito pamitsinje yonyowa. 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, tinthu kukula tsankho monga kusefera kapena mosamala, Kulekana kwakachulukidwe monga kupatula kwamkuntho kupatula yisiti ku fiber. These systems may be before or after the fermentation stage. Komabe, 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.
Mosiyana, dry processing methods are independent of the ethanol production process ndipo m'malo mwake gwiritsani ntchito mtsinje wa DDGS molunjika. Machitidwe otere nthawi zambiri amagwiritsa ntchito akupera, air classification, or dry sieving. Njira imodzi yatsopano imagwiritsa ntchito kupatula kwamagetsi kuti ipange mapuloteni apamwamba a DDGS pochotsa CHIKWANGWANI chopanda madzi, njira zakumbuyo zomwe sizimayenderana ndi kupanga kwa ethanol.
Electrostatics ndichinthu chodabwitsa chomwe pafupifupi aliyense adakumana nacho m'moyo watsiku ndi tsiku, koma ndi ochepa omwe adakumana nawo m'mafakitale. It is the effect of rubbing a balloon on a person’s hair. Monga buluni labala limakumana ndi tsitsi la munthu, amachotsa ma electron kumutu. Izi ndichifukwa choti ma labala komanso ma polima ambiri amakhala ndi ma electronegativity apamwamba (kuyandikana kwa ma elekitironi). Baluniyo imasiyidwa ndi chiwongola dzanja chonse, atapeza ma elekitironi owonjezera, ndipo tsitsi la mutuwo lili ndi chiphaso chabwino. Electrical charges repel each other, kotero tsitsi la mutuwo limayima kumapeto pofuna kuyesa kutalika pakati pazingwe zina zabwino kwambiri.
Pankhani ya 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 kulekana has been used by selected industries for many years. In mineral processing and recycling applications, kulekana electrostatic wakhala ntchito malonda kwa osachepera 50 zaka. Kupatukana kwa Electrostatic kwa zinthu zopangira mbewu kwakhala kukufufuzidwa kwazaka zambiri 140 zaka, ndi setifiketi woyamba wa kulekana electrostatic ufa wa tirigu middlings ada mangala kumayambiriro 1880.
posachedwapa, processing electrostatic walandira kwambiri chidwi monga njira kuganizira mapuloteni chomera. Zimenezi ali inapita patsogolo m'mbuyomu 10 kuti 20 zaka, ndi mayunivesite ambiri ofufuza ku Europe ndi US. kugwiritsa ntchito njira zopatulira zamagetsi pazinthu zosiyanasiyana kuphatikiza DDGS, chakudya oilseed, ndi mtola ndi zimachitika mapuloteni. Kuyambira kafukufuku, zikuonekeratu kuti njira electrostatic timatha kupanga latsopano, Mapuloteni azipatso zamtengo wapatali, ndikupereka njira ina yothandizira.
Njira kulekana electrostatic kupereka ubwino pa njira yonyowa kulekana, kuphatikiza kusinthasintha kwa mtengo ndi magwiridwe antchito kuchokera pakupanga kwa ethanol. Njira zopatukana ndi Electrostatic zimaperekanso mwayi wosowa mankhwala kapena madzi. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. Ndipo kulekana kwamagetsi ndikofatsa, popeza sasintha magwiridwe antchito a mapuloteni amtunduwu.
cha ku Switzerland Zida & Technology wakhala akugwiritsa electrostatic kulekana mu ntchito mafakitale kuyambira 1995. It is used to process fly ash from coal power plants. pa 20 matani miliyoni a mankhwala ntchentche phulusa kukonzedwa ndi olekanitsa STET anaika mu U.S. yekha.
Ngakhale kwa ena, repurposing technology to process fly ash (mchere wonyezimira wonyezimira womwe udatsalira chifukwa choyaka moto wamakala) Kuika mapuloteni azomera ku DDGS kumawoneka ngati achilendo. In truth, msika DDGS ndi msika ntchentche phulusa nawo kuchuluka zodabwitsa zofanana. Pongoyambira, 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. mafakitale a ethanol mu 2019. Poyerekeza, U.S.. malasha-mphamvu makampani kwaiye mozungulira 35 miliyoni mamilioni matani a ntchentche phulusa mkati 2017. Zogulitsa zonsezi zimagulitsidwa m'malire ochepa. 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. Kuuluka phulusa m'malo simenti, the most expensive component in ready-mix concrete. DDGS imapikisana ndi zina zama protein monga soya, canola, and sunflower meal, mwa ena.
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 yasinthanso chimodzimodzi, 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.
Pamapeto pake, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, kuphatikizapo mbewu za distiller, adzapitiliza. Kusintha matekinoloje apitiliza kukhala kofunikira pakukweza magwiridwe antchito a mapuloteni. komanso, shaping their value-creation potential for the ethanol industry.
Njira zamakonozi zidzafunika kuwonetsa magwiridwe antchito, kudalilika kwakukulu, low cost, and rapid return of capital to end users. Lumikizanani nafe now for more information.
