De réir mar a bhíonn corrlaigh ar tháirgí eatánóil níos doichte nó ag imeacht, roghnaíonn go leor táirgeoirí eatánóil díriú ar chruthú luacha ó chomh-tháirgí. Gráin driogairí triomaithe le intuaslagtha (DDGS) have long been an undervalued coproduct. Ach ag 28 chun 32 próitéin faoin gcéad, tá an iomarca próitéine ann chun a luach iomlán mar bheatha athchogantach a bhaint amach, agus ag an am céanna a bheith ró-íseal i bpróitéin le húsáid i gcóimheasa ard ionadaíochta do fhothaí monafastracha cosúil le dobharshaothrú, 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, sainmhínítear é mar bheatha a sholáthar d’ainmhí a chomhlíonann a riachtanais chothaithe go beacht. Deiseanna eile, such as the rapid growth of aquaculture and the high cost and limited availability of fish meals, treocht an mhargaidh seo a threisiú.
Tirim, Wet, and Electrostatics Le déanaí, multiple technologies have entered the market to address the need to generate high-protein coproducts. These technologies can be classified into two segments: iad siúd atá comhtháite leis an bpróiseas táirgthe eatánóil agus a oibríonn ar shruthanna próisis fliucha. 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, deighilt mhéid na gcáithníní mar scagachán nó scagadh, agus scaradh dlúis amhail scaradh cioclón chun giosta a scaradh ó shnáithín plandaí. These systems may be before or after the fermentation stage. ach, 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.
I gcodarsnacht leis sin, dry processing methods are independent of the ethanol production process agus ina ionad sin oibriú go díreach ar shruth DDGS. Is minic a úsáideann córais den sórt sin meilt, air classification, or dry sieving. Úsáideann cur chuige úrscéal amháin scaradh leictreastatach chun DDGS ardphróitéine a ghiniúint trí shnáithín a bhaint i réimse atá go hiomlán saor ó uisce, próiseas deiridh atá neamhspleách ar an bpróiseas táirgthe eatánóil.
Is feiniméan é leictreastatach a bhfuil taithí phearsanta ag beagnach gach duine air sa saol laethúil, ach is beag duine a tháinig i suíomh tionsclaíoch. It is the effect of rubbing a balloon on a person’s hair. De réir mar a thagann an balún rubair i dteagmháil le gruaig dhaonna, baintear leictreoin as an ghruaig. Tá sé seo toisc go bhfuil leictridhiúltacht ard ag rubar agus ag an gcuid is mó de pholaiméirí (cleamhnas le haghaidh leictreon). Fágtar glanmhuirear diúltach ar an mbalún, tar éis na leictreoin bhreise a charnadh, agus tá muirear dearfach ar ghruaig an ábhair. Electrical charges repel each other, mar sin seasann gruaig an ábhair ar deireadh mar iarracht an fad idir snáitheanna gruaige luchtaithe go dearfach a uasmhéadú.
I gcás 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. Scaradh leictreastatach has been used by selected industries for many years. In mineral processing and recycling applications, tá scaradh leictreastatach in úsáid go tráchtála ar a laghad 50 blianta. Tá imscrúdú déanta ar scaradh leictreastatach ábhar plandaí-bhunaithe 140 blianta, leis an gcéad phaitinn maidir le scaradh leictreastatach middlings plúr cruithneachta a comhdaíodh chomh luath le 1880.
Le déanaí, tugadh an-aird ar phróiseáil leictreastatach mar mhodh chun próitéiní plandaí a dhíriú. Tá sé seo forbairt luathaithe san am atá thart 10 chun 20 blianta, le go leor ollscoileanna taighde san Eoraip agus sna Stáit Aontaithe. teicnící deighilte leictreastatacha a chur i bhfeidhm ar réimse leathan ábhar lena n-áirítear DDGS, béilí síl ola, agus próitéiní pea agus cuisle. Ón taighde, is léir go bhfuil modhanna leictreastatach an cumas a ghiniúint nua, comhábhair agus táirgí próitéine plandaí ar luach níos airde, agus rogha eile a thairiscint ar mhodhanna próiseála fliuch.
Tugann modhanna deighilte leictreastatacha buntáistí thar mhodhanna scaradh fliuch, lena n-áirítear costas agus solúbthacht oibríochta ón bpróiseas táirgthe eatánóil. Tugann modhanna deighilte leictreastatacha an buntáiste freisin gan aon cheimiceáin ná uisce a cheangal. That makes cleaning easier since the rate of bacterial growth is reduced in dry products. Agus tá scaradh leictreastatach éadrom, sa mhéid is nach n-athraíonn sé feidhmiúlacht an phróitéin dhúchais.
ST Trealamh & Tá an teicneolaíocht ag úsáid scaradh leictreastatach in fheidhmeanna tionsclaíocha ó shin 1995. It is used to process fly ash from coal power plants. Thar 20 Tá na milliúin tonna fuinseoige eitilte táirge próiseáilte ag na deighilteoirí STET atá suiteáilte sna Stáit Aontaithe. ina n-aonar.
Cé go roinnt, repurposing technology to process fly ash (mianra aluminosilicate gloineach atá fágtha ó ghual a dhó le haghaidh cumhachta) is cosúil go bhfuil sé aisteach próitéin plandaí a dhíriú ó DDGS. In truth, tá an-chosúlacht idir an margadh DDGS agus an margadh fuinseog eitilt. Chun tosaigh, 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. tionscal eatánóil i 2019. I gcomparáid leis sin, na Stáit Aontaithe. tionscal cumhachta guail ginte timpeall 35 milliún tonna méadrach de luaithreach eitilte i 2017. Díoltar an dá tháirge ag corrlaigh ísle. 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. Cuir fuinseog in ionad stroighin, the most expensive component in ready-mix concrete. Tá DDGS in iomaíocht le foinsí próitéine eile cosúil le soy, canola, and sunflower meal, i measc daoine eile.
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. Tá éabhlóid den chineál céanna déanta ag 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.
I ndeireadh na dála, it looks likely that the long-term trend of maximizing the value of ethanol coproducts, gráin driogairí san áireamh, leanfaidh. Leanfaidh teicneolaíochtaí próiseála de bheith ríthábhachtach chun feidhmíocht theicniúil coproducts próitéine a uasmhéadú. chomh maith leis sin, shaping their value-creation potential for the ethanol industry.
Caithfidh na teicneolaíochtaí seo feidhmíocht chomhsheasmhach a thaispeáint, iontaofacht ard, low cost, and rapid return of capital to end users. Glaoigh orainn now for more information.
