Craft breweries inoshandisa CO2 muhuwandu hunoshamisa hwekushandisa mukubika, kurongedza uye kushumira maitiro: kufambisa doro kana chigadzirwa kubva kune tangi kuenda kune tangi, carbonizing chigadzirwa, kuchenesa okisijeni isati yarongedza, kurongedza doro mukuita, pre-flushing brit matangi mushure mekuchenesa. uye sanitizing, kubhodha doro rekudhirowa muresitorendi kana mubhawa.Izvi ndezvekutanga chete.
"Tinoshandisa CO2 mukati mekutengesa uye bar," anodaro Max McKenna, mutariri mukuru wekutengesa kuBoston-based Dorchester Brewing Co. Kushumira doro - pamatanho ose ekugadzirisa.”
Kufanana nevakawanda vanogadzira doro, Dorchester Brewing inotarisana nekushomeka kwehutano hwekutengesa CO2 inoda kushanda (verenga pamusoro pezvikonzero zvose zvekushaya uku pano).
"Nekuda kwezvibvumirano zvedu, vatengesi vedu veCO2 vemazuva ano havana kukwidza mitengo yavo pasinei nekuwedzera kwemitengo mune dzimwe nzvimbo dzemusika," akadaro McKenna."Parizvino, kukanganisa kwave kuri pakugovera kushoma."
Kubhadhara kushayikwa kwe CO2, Dorchester Brewing inoshandisa nitrogen panzvimbo ye CO2 mune dzimwe nguva.
"Takakwanisa kufambisa maoparesheni akawanda kune nitrogen," McKenna akaenderera mberi.“Zvimwe zvainyanya kukosha kwaiva kuchenesa magaba uye kuvhara gasi panguva yekuisa mumagaba uye kuvhara.Uku ndiko kuwedzera kukuru kwatiri nekuti maitiro aya anoda yakawanda CO2.Kwenguva refu takanga tine chirimwa chenitro chakakosha.Isu tinoshandisa yakakosha jenareta yenitrogen kugadzira iyo nitrogen yese yebhawa - kune yakatsaurirwa nitro mutsetse uye musanganiswa wedoro redu. "
N2 ndiyo yakanyanya hupfumi inert gasi kugadzira uye inogona kushandiswa mukugadzira doro repasi, zvitoro zvemabhodhoro nemabhawa.N2 yakachipa kupfuura CO2 yezvinwiwa uye kazhinji inowanikwa, zvichienderana nekuwanikwa kwaunogara.
N2 inogona kutengwa segasi mumasilinda ekumanikidza kana semvura muDewars kana matangi makuru ekuchengetedza.Nitrogen inogonawo kugadzirwa panzvimbo uchishandisa jenareta renitrogen.Majenareta eNitrogen anoshanda nekubvisa mamorekuru eokisijeni kubva mumhepo.
Nitrogen ndicho chinhu chakanyanya kuwanda (78%) mumhepo yePasi, chasara iokisijeni uye kutsvaga magasi.Inoitawo kuti ive nehushamwari hwezvakatipoteredza sezvaunoburitsa CO2 shoma.
Mukubika nekurongedza, N2 inogona kushandiswa kuchengetedza oxygen kubva mudoro.Kana yakashandiswa zvakanaka (vanhu vazhinji vanosanganisa CO2 neN2 pavanenge vachishanda ne carbonated beer) N2 inogona kushandiswa kuchenesa matangi, kutamisa doro kubva kune tangi kuenda kune tangi, kudzvinyirira kegs vasati vachengetedzwa, vachifambisa pasi pemakepisi.ingredient yekuravira uye muromo.Mumabhawa, nitro inoshandiswa mumitsetse yemvura yemupombi yenitropiv pamwe nepamusoro-soro/kureba kwekushandisa uko nitrogen inosanganiswa neimwe percent yeCO2 kudzivirira doro kuti risapupuke papombi.N2 inogona kutoshandiswa sebiira kubva gasi rekubvisa mvura kana ichi chiri chikamu chemaitiro ako.
Zvino, sezvatakambotaura munyaya yedu yapfuura pamusoro pekushomeka kweCO2, nitrogen haisi iyo chaiyo inotsiva CO2 mune zvese zvekubikisa doro.Magasi aya anoita zvakasiyana.Vane zviremu zvakasiyana-siyana zvema molecular uye zvakasiyana-siyana.
Semuenzaniso, CO2 inonyanya kunyungudika muzvinwiwa kupfuura N2.Ichi ndicho chikonzero nitrogen ichipa mabhuru madiki uye muromo wakasiyana mudoro.Ichi ndicho chikonzero vanobika doro vachishandisa mvura ine nitrogen madonhwe panzvimbo pegaseous nitrogen kuita doro re nitrate.Carbon dioxide inowedzerawo kuvava kana kuvava kusingaite nitrogen, izvo zvinogona kushandura flavour profile, vanhu vanodaro.Kuchinjira kunitrogen hakuzogadzirise matambudziko ese ecarbon dioxide.
“Kune bviro,” anodaro Chuck Skepek, mutungamiriri wezvirongwa zvokubika doro muunyanzvi paBrewers Institute, “asi nitrogen haisi mushonga kana kuti kugadzirisa nokukurumidza.CO2 uye nitrogen inoita zvakasiyana chaizvo.Iwe uchawana yakawanda nitrogen yakasanganiswa nemhepo mutangi kupfuura kana iwe ukachenesa CO2.Saka zvinoda nitrogen yakawanda.Izvi ndinonzwa kasingaperi.
“Mumwe mubiki wedoro wandinoziva akanga akachenjera zvikuru uye akatanga kutsiva carbon dioxide nenitrogen, uye doro ravo raiva neoxygen yakawanda mariri, saka zvino vava kushandisa musanganiswa wenitrogen necarbon dioxide, vaine rombo rakanaka.kwete kungoti, “Hei, tichatanga kushandisa nitrogen kugadzirisa matambudziko edu ese.Zvakanaka kuona zvakawanda pamusoro peizvi mumabhuku, tave kutanga kuona vanhu vazhinji vachinyatsoita tsvagiridzo, uye, munoziva, kuti vauye nemaitiro akanakisa ekutsiva uku.
Kuendeswa kwemagasi aya kuchave kwakasiyana sezvo aine madhindindi akasiyana izvo zvinogona kukonzera shanduko yeinjiniya kana kuchengetedza.Inzwa Jason Perkins, tenzi anobika doro paAllagash Brewing Co., kurukura nezvekusimudzira mutsara wake webhodhoro uye gasi manifold kuti ashandise CO2 yekumanikidza mbiya yekuzadza uye N2 ye sealant uye bubble breaker.Kuchengeta kunogona kusiyana.
"Zvechokwadi kune mimwe misiyano, zvimwe nekuda kwekuwana kwatinoita nitrogen," McKenna akadaro."Tinowana yakachena mvura nitrogen mudewars, saka kuichengeta kwakasiyana kwazvo nematangi edu eCO2: madiki, pama roller uye anochengetwa mufiriji.Takazviendesa kunext level.carbon dioxide to nitrogen, asi zvakare, takangwarira zvikuru pamusoro pekuita shanduko nemazvo uye zvine hungwaru kuti tive nechokwadi chekuti doro riri padanho rayo repamusoro nhanho dzese dzenzira.kiyi, mune dzimwe nguva yaive iri nyore plug uye yekutamba kutsiva, nepo mune dzimwe nguva yaida kuvandudzwa kwakakosha mumidziyo, zvivakwa, kugadzira, nezvimwe.

Zvinoenderana nechinyorwa ichi chakanakisa kubva kuThe Titus Co. (mutengesi wemhepo compressor, air compressor, uye air compressor masevhisi kunze kwePennsylvania), majenareta enitrogen anoshanda mune imwe yenzira mbiri:
Pressure swing adsorption: Pressure swing adsorption (PSA) inoshanda uchishandisa kabhoni molecular sieves kuparadzanisa mamorekuru.Sieve ine pores saizi yakafanana neyeokisijeni mamorekuru, ichiteya iwo mamorekuru paanopfuura nekubvumidza iwo mamorekuru enitrogen kupinda.Jenareta rinobva raburitsa oxygen neimwe kamuri.Mhedzisiro yeiyi nzira ndeyekuti kuchena kwe nitrogen kunogona kusvika 99.999%.
Membrane kugadzirwa kwenitrogen.Membrane nitrogen generation inoshanda nekuparadzanisa mamorekuru achishandisa polymer fibers.Mafayibha aya ane mhango, ane maburi epamusoro madiki anokwana kuti okisijeni ipfuure, asi idiki kwazvo kuti mamorekuru enitrogen abvise oxygen kubva murukova rwegasi.Majenareta anoshandisa nzira iyi anogona kugadzira nitrogen kusvika 99.5% yakachena.
Zvakanaka, iyo PSA nitrogen jenareta inogadzira nitrogen yakanyanyisa-pure muhuwandu hombe uye nekuyerera kwakanyanya, iyo yakachena fomu yenitrogen inodiwa nevakawanda vanogadzira doro.Ultrapure zvinoreva 99.9995% kusvika 99%.Majenareta enitrogen eMembrane akanakira mabikirwo edoro madiki anoda vhoriyamu yakaderera, inoyerera yakaderera apo 99% kusvika 99.9% kuchena kunogamuchirwa.
Uchishandisa tekinoroji yazvino, iyo Atlas Copco nitrogen jenareta ndeye compact maindasitiri emhepo compressor ine yakakosha diaphragm inoparadzanisa iyo nitrogen kubva kumhepo yakamanikidzwa.Craft breweries ihombe inotarirwa vateereri veAtlas Copo.Zvinoenderana nebepa jena reAtlas Copco, vanobika doro vanowanzobhadhara pakati pemadhora 0.10 nemadhora 0.15 pacubic tsoka kugadzira nitrogen panzvimbo.Izvi zvinofananidzwa sei nemitengo yako yeCO2?
"Tinopa mapakeji matanhatu akajairwa anovhara 80% yezvese mabikirwo - kubva kuzviuru zvishoma kusvika kumazana ezviuru zvemadhiramu pagore," anodaro Peter Askini, maneja webhizinesi rekusimudzira magasi emaindasitiri kuAtlas Copco.“Chigadzirwa chedoro chinogona kuwedzera huwandu hwemajenareta ayo enitrogen kuti akwanise kukura asi achichengetedza kushanda zvakanaka.Pamusoro pezvo, modular dhizaini inobvumira kuti jenareta rechipiri riwedzerwe kana mashandiro ebhiwa akawedzera zvakanyanya. "
"Kushandisa nitrogen hakurevi kutsiva zvachose CO2," anotsanangura Asquini, "asi isu tinofunga kuti vanogadzira winemaker vanogona kuderedza kushandiswa kwavo ne70%.Chinhu chikuru chinotyaira ndiko kuenderera mberi.Zviri nyore kwazvo kune chero winemaker kugadzira nitrogen ivo pachavo.Musashandise mamwe magasi egreenhouse.”izvo zviri nani kune zvakatipoteredza Ichabhadhara kubva pamwedzi wekutanga, iyo inobata zvakananga pasi, kana isingaratidzi usati watenga, usatenga.Heino mitemo yedu iri nyore.Kudiwa kwe CO2 iri kukwira mudenga kugadzira zvigadzirwa zvakadai sechando chakaoma, chinoshandisa CO2 yakawanda uye inodiwa kutakura mishonga yekudzivirira.Breweries muUS vari kuratidza kushushikana pamusoro pehuwandu hwekupihwa uye kushamisika kana vachikwanisa kuchengetedza mutengo unoenderana nezvinodiwa nebiki. "
Sezvambotaurwa, kuchena kwenitrogen kuchava kunetseka kukuru kune vanogadzira doro.Kungofanana neCO2, nitrogen inopindirana nedoro kana wort uye inotakura tsvina pamwe chete nayo.Ichi ndicho chikonzero majenareta enitrogen akawanda echikafu nechinwiwa achizoshambadzirwa sezvikamu zvisina mafuta (dzidza nezverucheno rwemacompressor asina mafuta mumutsara wekupedzisira mudivi repazasi).
"Patinogamuchira CO2, tinoongorora kunaka kwayo uye kusvibiswa, icho chimwe chikamu chakakosha chekushanda nemupi akanaka," akadaro McKenna.“Nitrogen yakati siyanei, ndosaka tichiri kutenga pure liquid nitrogen.Chimwe chinhu chatiri kutarisa kutsvaga nemitengo yemukati nitrogen jenareta - zvakare, nekutarisa kune iyo nitrogen yainogadzira nePurity kudzikamisa kutorwa kweokisijeni.Isu tinoona izvi sezvingangoita mari, saka maitiro ega ega mubiki anoenderana zvachose ne CO2 ichava doro carbonation uye pombi yekugadzirisa mvura.
"Asi chimwe chinhu chakakosha kuchengeta mupfungwa - zvakare, chimwe chinhu chinoita sechisingatarisirwe asi chakakosha kuchengetedza mhando yedoro - ndechekuti chero jenareta renitrogen rinoda kuburitsa nitrogen kunzvimbo yechipiri yegumi [kureva 99.99% kuchena] kudzikamisa okisijeni. kutora uye njodzi ye oxidation.Iyi nhanho yehuchokwadi uye kuchena inoda mari yakawanda yejenareta yenitrogen, asi inovimbisa kunaka kwenitrogen uye nekudaro kunaka kwedoro.

Vanogadzira doro vanoda data rakawanda uye kutonga kwemhando kana uchishandisa nitrogen.Semuenzaniso, kana mubiki wedoro akashandisa N2 kufambisa doro pakati pematangi, kugadzikana kweCO2 mutangi uye mutangi kana bhodhoro kunofanirwa kuongororwa mukati mekuita.Mune zvimwe zviitiko, N2 yakachena inogona kusashanda nemazvo (semuenzaniso, pakuzadza midziyo) nekuti N2 yakachena inobvisa CO2 kubva mumhinduro.Nekuda kweizvozvo, vamwe vanobika doro vachashandisa 50/50 musanganiswa we CO2 neN2 kuzadza ndiro, nepo vamwe vachiidzivirira zvachose.
N2 Pro Tip: Ngatitaurei kugadzirisa.Majenareta eNitrogen ari padyo ne "kuiisa uye kuikanganwa" sezvaunogona kuwana, asi zvimwe zvinoshandiswa, senge mafirita, zvinoda semi-nguva dzose kutsiva.Kazhinji, sevhisi iyi inodiwa angangoita maawa 4000 ega ega.Chikwata chimwe chete icho chinotarisira yako mhepo compressor ichatarisirawo jenareta yako.Mazhinji majenareta anouya neine nyore controller yakafanana ne iPhone yako uye inopa yakazara app kure yekutarisa kugona.
Tank purge inosiyana nenitrogen purge nekuda kwezvikonzero zvakati.N2 inosanganiswa zvakanaka nemhepo, saka haidyidzane neO2 sezvinoita CO2.N2 zvakare yakareruka kupfuura mhepo, saka inozadza tangi kubva kumusoro kusvika pasi, nepo CO2 ichizadza kubva pasi kuenda kumusoro.Zvinotora yakawanda N2 kupfuura CO2 kuchenesa tangi rekuchengetedza uye kazhinji inoda kuputika kwepfuti.Uchiri kuchengeta mari here?
Nyaya dzekuchengetedza nyowani dzinomukawo negasi idzva remumaindasitiri.Biro rinofanirwa kuisa maO2 sensors kuitira kuti vashandi vagone kuona mukati memukati mhando yemhepo - senge iwe une N2 dewars yakachengetwa mumafiriji mazuva ano.
Asi purofiti inogona kupfuura zviri nyore CO2 kudzoreredza zvidyarwa.Mune iyi webinar, Dion Quinn weFoth Production Solutions (injiniya femu) inotaura kuti kugadzirwa kweN2 kunodhura pakati pemadhora masere nemadhora makumi maviri patani, ukuwo kubata CO2 nechirimwa chekudzoreredza kunodhura pakati pemadhora makumi mashanu nemadhora mazana maviri patani.
Zvakanakira majenareta enitrogen anosanganisira kubvisa kana kudzikisa kutsamira pazvibvumirano uye zvekushandisa zve CO2 nenitrogen.Izvi zvinochengetedza nzvimbo yekuchengetera sezvo mabikirwo edoro anogona kugadzira uye kuchengeta zvakawanda sezvavanoda, kubvisa kudiwa kwekuchengeta uye kutakura mabhodhoro enitrogen.Sezvakaita CO2, kutumira uye kubata kwenitrogen kunobhadharwa nemutengi.Ne nitrogenerator, iyi haisisiri dambudziko.
Majenareta eNitrogen anowanzo kuve nyore kubatanidza munzvimbo yekubikira doro.Majenareta madiki enitrogen anogona kuvharirwa madziro kuitira kuti asatore nzvimbo yepasi uye ashande chinyararire.Aya mabhegi anobata kuchinjika tembiricha zvakanaka uye anoshingirira zvakanyanya kushanduka kwetembiricha.Inogona kuiswa kunze, asi isingakurudzirwe kune yakanyanyisa yakakwirira uye yakaderera mamiriro ekunze.
Kune vakawanda vanogadzira majenareta enitrogen anosanganisira Atlas Copco, Parker Hannifin, South-Tek Systems, Milcarb uye Holtec Gas Systems.Jenareta diki yenitrogen inogona kuita madhora mazana masere pamwedzi pasi pechirongwa chemakore mashanu ekurenda-kune-chake, Asquini akadaro.
"Pakupera kwezuva, kana nitrogen yakakunakira iwe, une zvakasiyana-siyana zvevatengesi uye matekinoroji ekusarudza kubva," akadaro Asquini.“Tsvaga kuti ndeipi yakakunakira uye ita shuwa kuti une nzwisiso yakanaka yemutengo wakakwana wevaridzi [mutengo wose wevaridzi] uye enzanisa simba nemitengo yekugadzirisa pakati pemidziyo.Kazhinji uchaona kuti kutenga zvakachipa hazvina kukodzera basa rako .”
Nitrogen jenareta masisitimu anoshandisa air compressor, uye mazhinji ekugadzira mabikirwo atove ane imwe, iyo inoshanda.
Ndeapi air compressor anoshandiswa mukugadzira doro?Inosairira mvura nemumapombi nematangi.Simba rekufambisa kwepneumatic uye kutonga.Aeration ye wort, mbiriso kana mvura.control valve.Bvisa gasi kumanikidza dhaka kubva mumatangi panguva yekuchenesa uye kubatsira mukutsvaira gomba.
Mazhinji madhiri ekushandisa anoda kushandiswa kwakakosha kwe100% oiri-isina air compressors.Kana mafuta akasangana nedoro, anouraya mbiriso uye anoita kuti furo riyerere, iro rinokanganisa chinwiwa uye rinoita kuti doro rive rakaipa.
Izvo zvakare njodzi yekuchengetedza.Nekuti iyo indasitiri yechikafu nechinwiwa inonetseka zvakanyanya, kune yakasimba mhando uye kuchena zviyero munzvimbo, uye nenzira kwayo.Muenzaniso: Sullair SRL yakatevedzana mafuta-isina mweya compressors kubva gumi kusvika gumi nemashanu hp.(kubva pa7.5 kusvika ku11 kW) akanyatsokodzera mabhii ekubika.Vanobika doro vanonakidzwa nekunyarara kwemhando idzi dzemichina.Iyo SRL nhevedzano inopa yakaderera ruzha mazinga kusvika ku48dBA, ichiita iyo compressor yakakodzera kushandiswa kwemukati pasina yakasarudzika kamuri inonzwika.
