Hei tawhā i ngā hua ethanol whakakikīa, nunumi rānei, he maha ngā ethanol producers kōwhiria hei arotahi i te uara i waihanga mai i coproducts. Distillers maroke tātaikore me solubles (DDGS) have long been an undervalued coproduct. Engari i 28 ki 32 pūmua ōrau, he nui rawa te pūmua hei mōhio ki tōna uara katoa hei whāngai ruminant, ahakoa i te wā kotahi he iti rawa te pūmua hei whakamahi i roto i ngā ōwehenga whakakapinga tiketike mō ngā whāngai taetahi pēnei i te kikorangi, 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, kua tautuhia hei whakarato kararehe ki te whāngai e tutuki tonu ana i ōna whakaritenga kai. Ētahi atu huarahi, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, whakapakari i tēnei ia mākete.
Dry, Wet, and Electrostatics Aita i maoro a'e, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: ērā e whakakotahitia ana ki te tukanga whakanao ethanol, ā, ka mahi i runga i ngā roma tukanga mākū. 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, rahi korakora pēnei i te whakakotahitanga, te whakamātautau rānei, me te wehenga kiato pēnei i te wehenga huripari ki te wehe i te yeast i te tāka tipu. These systems may be before or after the fermentation stage. Heoi, 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.
Mā te pūrata, dry processing methods are independent of the ethanol production process ā, ka mahi hāngai kē ki te roma DDGS. I te nuinga o te wā e whakamahi ana aua pūnaha i te hurihuri, air classification, or dry sieving. One novel approach uses electrostatic separation to generate high-protein DDGS by removing fiber in an entirely water-free, tukanga whakamutunga-muri ehara i te tukanga whakanao ethanol.
He tītohunga te pateko, tata tonu ki te katoa kua pā ki te ringa tuatahi i roto i te oranga o ia rā, engari he takitahi kua tūtaki i roto i tētahi tautuhinga mahi. It is the effect of rubbing a balloon on a person’s hair. I te whakapā mai o te pūangi inarapa ki ngā makawe tangata, ka tangohia e ia ngā irahiko i nga makawe. Nā te mea he nui te irahiko o te inarapa me te nuinga o nga waerau (affinity mo nga irahiko). Ka waiho te pūangi ki tētahi utu tōraro kupenga, kua whakaemi i nga irahiko tāpiri, ā, he utu tōrunga te makawe o te kaupapa. Electrical charges repel each other, nā reira ko nga makawe o te kaupapa e tū ana i te mutunga o te whakamōrahi i te tawhiti i waenganui i ētahi atu aho makawe i whakahikotia tikatia.
I te take o 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. wehenga hiko has been used by selected industries for many years. In mineral processing and recycling applications, Kua whakamahia arumonitia te wehenga hiko mō te itinga rawa 50 tau. Kua uiuitia te wehenga hiko o ngā rauemi pūtake tipu mō tua atu i 140 tau, me te ārai tuatahi mo te wehenga hiko o te parāoa witi i kōnaetia i te wā tata tonu o te 1880.
Aita i maoro a'e, Kua whiwhi te tukanga patehiko i te nui o te aro atu hei tikanga kia āta whakaaro ai ki ngā pūmua tipu. Kua whakatere tēnei whanaketanga i mua 10 ki 20 tau, me te maha o ngā whare wānanga rangahau i Uropi me te U.S. hoatu ana i ngā pūkenga wehenga hiko ki ngā rauemi maha tae atu ki DDGS, kai oilseed, me ngā pūmua pī me te patupatu. Mai i tēnei rangahau, Ko reira kitea e tikanga hiko i te pūmanawa ki te whakaputa hou, ngā mea pūmua me ngā hua o te pūmua tipu uara tiketike, me te tuku i tētahi atu whiringa ki ngā aratuka tukatuka mākū.
Ko ngā tikanga o te wehenga hiko e tuku ana i ngā painga i runga i ngā tikanga wehenga mākū, tae atu ki te utu me te ngāwari ake i te tukanga whakanao ethanol. Ka tukuna hoki e ngā tikanga wehenga hiko te painga o te hiahia kāore he matū, he wai rānei. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. A, he māmā te wehenga hiko, ki te kore e huri i te taumahinga o te pūmua māori.
ST Taputapu & Kua whakamahia e te hangarau te wehenga hiko i roto i ngā taupānga mahi mai i 1995. It is used to process fly ash from coal power plants. Neke atu i te 20 E hia miriona ngā tāne rere hua kua tukatukatia e ngā whakawehe STET kua tāutatia ki te U.S. ko ia anake.
Ahakoa ki ētahi, repurposing technology to process fly ash (he kohuke karaehe e toe ana i te waro wera mo te hiko) he rerekē pea te āhua o te pūmua tipu mai i DDGS. In truth, ko te mākete DDGS me te mākete rehu rere e tiritiri ana i te nui o ngā ritenga whakamīharo. Mō ngā tīmata, 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. mahi ethanol i roto i 2019. Mā te whakataurite, te U.S. mahi hiko waro i puta noa 35 miriona ngahuru o te rere rere i roto i 2017. Ka hokona ngā hua e rua ki ngā tawhē iti. 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. Ngā whakakapi rere ash mō te raima, the most expensive component in ready-mix concrete. E whakataetae ana te DDGS ki ētahi atu pūtake pūmua pēnei i te soy, awa, and sunflower meal, i waenganui i ētahi atu.
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. He ōrite te kunenga o DDGS, 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.
Mutunga, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, tae atu ki ngā kākano rongoā, ka haere tonu. Ka tino nui tonu te tukatuka hangarau ki te whakamōrahi i te mahinga hangarau o ngā pūmua pūmua. hoki, shaping their value-creation potential for the ethanol industry.
Me whakaatu ēnei hangarau i te mahinga ōrite, whaikikotanga tiketike, low cost, and rapid return of capital to end users. Whakapā mai now for more information.
