Craft breweries siv CO2 nyob rau hauv ib tug xav tsis thoob ntawm daim ntaub ntawv nyob rau hauv lub brewing, ntim thiab ua hauj lwm txheej txheem: tsiv npias los yog cov khoom los ntawm lub tank mus rau lub tank, carbonizing ib yam khoom, purifying oxygen ua ntej ntim, ntim npias nyob rau hauv tus txheej txheem, pre-flushing brit tank tom qab ntxuav. thiab ntxuav, bottling npias hauv tsev noj mov lossis bar.Qhov no tsuas yog rau cov pib xwb.
"Peb siv CO2 thoob plaws hauv brewery thiab bar," hais tias Max McKenna, tus thawj coj loj ntawm kev lag luam ntawm Boston-based Dorchester Brewing Co. Pab npias - ntawm txhua theem ntawm cov txheej txheem.”
Zoo li ntau cov khoom siv tes ua breweries, Dorchester Brewing tab tom ntsib qhov tsis txaus ntawm kev lag luam zoo CO2 nws yuav tsum tau ua haujlwm (nyeem txog txhua qhov laj thawj ntawm qhov tsis txaus no ntawm no).
"Vim peb cov ntawv cog lus, peb cov neeg muab khoom CO2 tam sim no tsis tau nce lawv cov nqi txawm tias tus nqi nce hauv lwm qhov ntawm lub khw," McKenna tau hais."Txog tam sim no, qhov cuam tshuam tau feem ntau ntawm kev faib tawm tsawg."
Txhawm rau them nyiaj rau qhov tsis muaj CO2, Dorchester Brewing siv nitrogen hloov CO2 hauv qee kis.
McKenna hais ntxiv tias "Peb muaj peev xwm txav tau ntau yam haujlwm mus rau nitrogen.""Qee qhov tseem ceeb tshaj plaws tau ntxuav cov kaus poom thiab npog cov roj thaum lub sijhawm ua cov kaus poom thiab ntim cov txheej txheem.Qhov no yog qhov sib ntxiv loj tshaj plaws rau peb vim tias cov txheej txheem no xav tau CO2 ntau.Rau ib ntev lub sij hawm peb muaj ib tug tshwj xeeb nitro nroj tsuag.Peb siv lub tshuab hluav taws xob tshwj xeeb nitrogen los tsim tag nrho cov nitrogen rau lub bar - rau cov kab mob nitro thiab peb cov npias sib xyaw. "
N2 yog cov roj inert uas pheej yig tshaj plaws los tsim thiab tuaj yeem siv rau hauv cov khoom siv hauv tsev hauv qab daus, lub raj mis khw thiab tuav.N2 yog pheej yig dua CO2 rau cov dej qab zib thiab feem ntau muaj ntau dua, nyob ntawm qhov muaj nyob hauv koj cheeb tsam.
N2 tuaj yeem yuav los ua cov roj hauv lub tog raj kheej siab lossis ua kua hauv Dewars lossis cov tso tsheb hlau luam loj.Nitrogen kuj tuaj yeem tsim tawm ntawm qhov chaw siv lub tshuab hluav taws xob nitrogen.Nitrogen generators ua haujlwm los ntawm kev tshem tawm cov pa oxygen molecules los ntawm huab cua.
Nitrogen yog cov khoom uas muaj ntau tshaj plaws (78%) hauv lub ntiaj teb huab cua, qhov seem yog cov pa oxygen thiab cov pa roj.Nws kuj ua rau nws tus phooj ywg zoo dua qub thaum koj tso CO2 tsawg dua.
Hauv brewing thiab ntim, N2 tuaj yeem siv los khaws cov pa tawm ntawm npias.Thaum siv kom zoo (feem ntau cov neeg sib xyaw CO2 nrog N2 thaum ua haujlwm nrog carbonated npias) N2 tuaj yeem siv los ntxuav cov tso tsheb hlau luam, hloov npias los ntawm lub tank mus rau lub tank, pressurize kegs ua ntej cia, thaum aerating hauv qab hau.cov khoom xyaw rau saj thiab mouthfeel.Nyob rau hauv cov tuav, nitro yog siv nyob rau hauv kais dej kab rau nitropiv raws li zoo raws li kev kub siab / ntev daim ntaub ntawv uas nitrogen yog tov nrog ib tug tej feem pua ntawm CO2 los tiv thaiv npias los ntawm foaming rau kais.N2 tuaj yeem siv tau los ua cov roj boils rau dej degassing yog tias qhov no yog ib feem ntawm koj cov txheej txheem.
Tam sim no, raws li peb tau hais hauv peb tsab xov xwm dhau los ntawm CO2 tsis txaus, nitrogen tsis yog qhov hloov pauv rau CO2 hauv txhua daim ntawv thov brewing.Cov pa roj no coj txawv txawv.Lawv muaj qhov sib txawv molecular hnyav thiab sib txawv ntom.
Piv txwv li, CO2 soluble hauv cov kua ntau dua N2.Qhov no yog vim li cas nitrogen muab cov npuas me thiab sib txawv qhov ncauj hauv npias.Qhov no yog vim li cas brewers siv kua nitrogen tee es tsis txhob gaseous nitrogen rau nitrate npias.Cov pa roj carbon dioxide kuj ntxiv cov ntsiab lus ntawm iab lossis qaub uas tsis muaj nitrogen, uas tuaj yeem hloov qhov tsw profile, tib neeg hais.Hloov mus rau nitrogen yuav tsis daws txhua yam teeb meem carbon dioxide.
"Muaj peev xwm," hais tias Chuck Skepek, tus thawj coj ntawm cov kev pabcuam brewing ntawm Brewers Institute, "tab sis nitrogen tsis yog panacea lossis kho sai.CO2 thiab nitrogen coj txawv txawv.Koj yuav tau txais nitrogen ntau nrog cov huab cua hauv lub tank dua yog tias koj ntxuav cov CO2.Yog li nws yuav xav tau nitrogen ntau dua.Kuv hnov qhov no ntau zaus.
"Ib tug brewer kuv paub yog tiag tiag ntse thiab pib hloov carbon dioxide nrog nitrogen, thiab lawv cov npias muaj oxygen ntau nyob rau hauv nws, yog li tam sim no lawv siv ib tug sib tov ntawm nitrogen thiab carbon dioxide, muaj hmoo me ntsis.tsis yog, "Hav, peb yuav pib siv nitrogen los daws txhua yam ntawm peb cov teeb meem.Nws yog qhov zoo kom pom ntau ntxiv txog qhov no hauv cov ntaub ntawv, peb tab tom pib pom ntau tus neeg ua qee qhov kev tshawb fawb, thiab koj paub, los nrog cov kev coj ua zoo tshaj plaws rau kev hloov pauv no.
Kev xa tawm ntawm cov pa roj no yuav txawv raws li lawv muaj qhov sib txawv uas yuav ua rau qee qhov kev tsim khoom lossis kev hloov pauv.Hnov Jason Perkins, tus tswv brewer ntawm Allagash Brewing Co., sib tham txog kev txhim kho nws lub raj mis kab thiab roj manifold siv CO2 rau lub tais ntim ntim thiab N2 rau sealant thiab npuas tawg.Kev khaws cia yuav txawv.
"Muaj qee qhov sib txawv, ib feem yog vim li cas peb tau txais nitrogen," McKenna tau hais."Peb tau txais cov kua nitrogen ntshiab hauv dewars, yog li khaws cia nws txawv ntawm peb cov CO2 tso tsheb hlau luam: lawv me dua, ntawm cov chais thiab khaws cia hauv lub tub yees.Peb tau coj nws mus rau qib tom ntej.carbon dioxide rau nitrogen, tab sis dua, peb tau ceev faj heev txog yuav ua li cas hloov pauv tau zoo thiab muaj lub luag haujlwm kom paub tseeb tias lub npias nyob ntawm nws qib siab tshaj txhua kauj ruam ntawm txoj kev.qhov tseem ceeb, qee zaum nws yog qhov hloov pauv yooj yim heev thiab ua si, thaum lwm qhov nws xav tau kev txhim kho tseem ceeb hauv cov ntaub ntawv, infrastructure, kev tsim khoom, thiab lwm yam. "
Raws li tsab xov xwm no zoo heev los ntawm The Titus Co. (tus xa khoom ntawm cov tshuab cua compressors, cua tshuab ziab khaub ncaws, thiab cov kev pabcuam cua compressor sab nraum Pennsylvania), cov tshuab hluav taws xob nitrogen ua haujlwm hauv ib qho ntawm ob txoj hauv kev:
Siab viav vias adsorption: Siab viav vias adsorption (PSA) ua haujlwm siv cov pa roj carbon molecular sieves cais cov molecules.Lub sieve muaj qhov pores loj tib yam li cov pa oxygen molecules, ntxiab cov molecules thaum lawv hla thiab tso cai rau cov nitrogen loj dua los ntawm.Lub tshuab hluav taws xob ces tso pa oxygen los ntawm lwm chav.Qhov tshwm sim ntawm cov txheej txheem no yog tias nitrogen purity tuaj yeem ncav cuag 99.999%.
Membrane tiam ntawm nitrogen.Membrane nitrogen tiam ua haujlwm los ntawm kev sib cais molecules siv polymer fibers.Cov fibers no hollow, nrog rau qhov pores me me txaus kom cov pa oxygen dhau mus, tab sis me me heev rau nitrogen molecules kom tshem tawm cov pa tawm ntawm cov pa roj.Cov tshuab hluav taws xob siv txoj kev no tuaj yeem tsim cov nitrogen mus txog 99.5% ntshiab.
Zoo, PSA nitrogen generator tsim ultra-ntshiab nitrogen nyob rau hauv loj ntim thiab nyob rau hauv siab txaus tus nqi, lub purest daim ntawv ntawm nitrogen uas ntau breweries xav tau.Ultrapure txhais tau tias 99.9995% rau 99%.Membrane nitrogen generators yog zoo tagnrho rau me me breweries uas yuav tsum tau ib tug tsawg ntim, tsawg txaus lwm txoj kev uas 99% mus rau 99.9% purity yog tau.
Siv cov thev naus laus zis tshiab, Atlas Copco nitrogen generator yog lub tshuab cua compressor compact nrog lub diaphragm tshwj xeeb uas cais cov nitrogen los ntawm cov cua compressed.Craft breweries yog lub hom phiaj loj rau Atlas Copo.Raws li Atlas Copco daim ntawv dawb, brewers feem ntau them ntawm $ 0.10 thiab $ 0.15 ib cubic feet los tsim nitrogen ntawm qhov chaw.Qhov no piv rau koj cov nqi CO2 li cas?
Peter Askini, tus thawj coj txhim kho kev lag luam rau kev lag luam gases ntawm Atlas Copco hais tias "Peb muab rau 6 pob khoom siv uas npog 80% ntawm tag nrho cov breweries - los ntawm ob peb txhiab mus rau ntau pua txhiab lub thoob hauv ib xyoos."Lub brewery tuaj yeem ua kom muaj peev xwm ntawm nws cov tshuab hluav taws xob nitrogen kom muaj kev loj hlob thaum tswj kev ua haujlwm.Tsis tas li ntawd, tus qauv tsim qauv tso cai rau lub tshuab hluav taws xob thib ob ntxiv yog tias lub chaw ua haujlwm brewery nthuav dav heev. "
"Siv nitrogen tsis yog los hloov CO2 kiag li," piav qhia Asquini, "tab sis peb xav tias cov neeg tsim khoom lag luam tuaj yeem txo lawv cov kev noj haus li ntawm 70%.Lub zog tsav tsheb tseem ceeb yog sustainability.Nws yooj yim heev rau txhua tus winemaker los tsim nitrogen ntawm lawv tus kheej.Tsis txhob siv ntau lub tsev cog khoom gases. "uas yog qhov zoo dua rau ib puag ncig Nws yuav them tawm ntawm thawj lub hlis, uas yuav cuam tshuam ncaj qha rau hauv qab kab, yog tias nws tsis tshwm sim ua ntej koj yuav, tsis txhob yuav nws.Ntawm no yog peb txoj cai yooj yim.Qhov kev thov rau CO2 yog skyrocketing los tsim cov khoom zoo li no, xws li cov dej khov qhuav, uas siv CO2 ntau thiab xav tau los thauj cov tshuaj tiv thaiv.Breweries hauv Asmeskas tau qhia txog kev txhawj xeeb txog qib ntawm cov khoom siv thiab xav tsis thoob yog tias lawv tuaj yeem ua kom tus nqi sib txawv raws li qhov xav tau ntawm lub brewery. "
Raws li tau hais ua ntej, nitrogen purity yuav yog ib qho kev txhawj xeeb loj rau cov khoom siv tes ua brewers.Ib yam li CO2, nitrogen yuav cuam tshuam nrog npias lossis wort thiab nqa impurities nrog rau nws.Qhov no yog vim li cas ntau cov khoom noj thiab dej haus nitrogen generators yuav raug tshaj tawm raws li cov roj-dawb units (kawm txog cov txiaj ntsig kev huv ntawm cov roj tsis muaj roj compressors nyob rau kab lus kawg hauv kab lus hauv qab no).
McKenna hais tias "Thaum peb tau txais CO2, peb xyuas nws qhov zoo thiab kev sib kis, uas yog lwm qhov tseem ceeb ntawm kev ua haujlwm nrog tus neeg xa khoom zoo," McKenna hais."Nitrogen txawv me ntsis, uas yog vim li cas peb tseem yuav cov kua nitrogen ntshiab.Lwm qhov uas peb tab tom saib yog nrhiav thiab nqi ib lub tshuab hluav taws xob sab hauv nitrogen - dua, nrog rau kev tsom mus rau nitrogen nws tsim nrog Purity los txwv cov pa oxygen.Peb pom qhov no yog qhov peev txheej peev, yog li tsuas yog cov txheej txheem hauv brewery uas nyob ntawm CO2 tag nrho yuav yog npias carbonation thiab kais dej tu.
"Tab sis ib qho tseem ceeb heev uas yuav tsum nco ntsoov - dua, ib yam dab tsi zoo li yuav tsis saib xyuas tab sis tseem ceeb heev rau kev tswj hwm npias zoo - yog tias txhua lub tshuab hluav taws xob nitrogen yuav tsum tsim cov nitrogen rau qhov thib ob qhov chaw [piv txwv li 99.99% purity] kom txwv cov pa oxygen. uptake thiab kev pheej hmoo ntawm oxidation.Qhov no theem ntawm qhov tseeb thiab purity yuav tsum tau ntau nitrogen generator nqi, tab sis xyuas kom meej cov nitrogen zoo thiab yog li ntawd lub npias zoo. "
Brewers xav tau ntau cov ntaub ntawv thiab kev tswj kom zoo thaum siv nitrogen.Piv txwv li, yog tias tus brewer siv N2 txav npias ntawm cov tso tsheb hlau luam, kev ruaj ntseg ntawm CO2 hauv lub tank thiab hauv lub tank lossis lub raj mis yuav tsum tau saib xyuas thoob plaws hauv cov txheej txheem.Qee zaum, N2 ntshiab yuav tsis ua haujlwm zoo (piv txwv li, thaum ntim ntim) vim tias N2 ntshiab yuav tshem CO2 los ntawm kev daws.Raws li qhov tshwm sim, qee tus brewers yuav siv 50/50 sib xyaw ntawm CO2 thiab N2 los sau lub tais, thaum lwm tus yuav zam nws tag nrho.
N2 Pro Lub Tswv Yim: Cia peb tham txog kev saib xyuas.Nitrogen generators tiag tiag yog ze rau "teeb nws thiab tsis nco qab nws" raws li koj tuaj yeem tau txais, tab sis qee qhov khoom siv, xws li lim, yuav tsum tau hloov ib nrab.Feem ntau, qhov kev pabcuam no yuav tsum muaj kwv yees li 4000 teev.Tib pab neeg uas saib xyuas koj lub tshuab cua compressor kuj yuav saib xyuas koj lub tshuab hluav taws xob.Feem ntau lub tshuab hluav taws xob tuaj nrog tus maub los yooj yim zoo ib yam li koj lub iPhone thiab muaj peev xwm saib xyuas cov chaw taws teeb tag nrho.
Tank tshem tawm txawv ntawm nitrogen ntxuav rau ntau yam.N2 sib tov zoo nrog huab cua, yog li nws tsis cuam tshuam nrog O2 zoo li CO2 ua.N2 tseem sib zog dua huab cua, yog li nws puv lub tank los ntawm sab saum toj mus rau hauv qab, thaum CO2 puv nws los ntawm qab mus rau saum.Nws yuav siv ntau N2 tshaj CO2 los ntxuav lub tank cia thiab feem ntau yuav tsum tau txhaj tshuaj ntau dua.Koj puas tseem txuag nyiaj?
Cov teeb meem kev nyab xeeb tshiab kuj tshwm sim nrog cov roj av tshiab.Lub brewery yuav tsum tau teeb tsa O2 sensors kom cov neeg ua haujlwm pom cov huab cua zoo hauv tsev - ib yam li koj muaj N2 dewars khaws cia hauv tub yees hnub no.
Tab sis profitability tau yooj yim tshaj CO2 rov qab cov nroj tsuag.Hauv qhov webinar no, Dion Quinn ntawm Foth Production Solutions (ib lub tuam txhab engineering) hais tias N2 cov nqi tsim tawm ntawm $ 8 thiab $ 20 ib tuj, thaum ntes CO2 nrog cov nroj tsuag rov qab los ntawm $ 50 thiab $ 200 ib tuj.
Cov txiaj ntsig ntawm cov tshuab hluav taws xob nitrogen suav nrog kev tshem tawm lossis tsawg kawg txo kev cia siab ntawm kev cog lus thiab khoom siv ntawm CO2 thiab nitrogen.Qhov no txuag chaw cia li breweries tuaj yeem tsim thiab khaws ntau npaum li lawv xav tau, tshem tawm qhov xav tau khaws cia thiab thauj cov fwj nitrogen.Raws li nrog CO2, shipping thiab tuav ntawm nitrogen yog them los ntawm cov neeg siv khoom.Nrog nitrogenerators, qhov no tsis yog teeb meem lawm.
Nitrogen generators feem ntau yooj yim rau kev koom ua ke rau hauv ib puag ncig brewery.Cov tshuab hluav taws xob me me tuaj yeem ua rau phab ntsa kom lawv tsis txhob siv qhov chaw hauv pem teb thiab ua haujlwm ntsiag to.Cov hnab no hloov pauv qhov kub thiab txias zoo heev thiab tiv taus qhov kub thiab txias.Nws tuaj yeem ntsia tau rau sab nraum zoov, tab sis tsis pom zoo rau huab cua siab thiab qis.
Muaj ntau lub tuam txhab tsim hluav taws xob nitrogen xws li Atlas Copco, Parker Hannifin, South-Tek Systems, Milcarb thiab Holtec Gas Systems.Ib lub tshuab hluav taws xob me me tuaj yeem raug nqi txog $ 800 ib hlis raws li kev xauj tsev tsib xyoos rau tus kheej, Asquini tau hais.
Asquini tau hais tias "Thaum hnub kawg, yog tias nitrogen haum rau koj, koj muaj ntau tus neeg muab khoom thiab thev naus laus zis xaiv los ntawm," Asquini tau hais."Nrhiav qhov twg yog qhov tsim nyog rau koj thiab xyuas kom koj muaj kev nkag siab zoo ntawm tag nrho cov nqi ntawm cov tswv cuab [tag nrho cov nqi ntawm cov tswv] thiab sib piv cov nqi hluav taws xob thiab kev saib xyuas ntawm cov khoom siv.Feem ntau koj yuav pom tias yuav qhov pheej yig tshaj tsis yog rau koj txoj haujlwm. "
Nitrogen generator tshuab siv lub tshuab cua compressor, thiab feem ntau cov khoom siv tes ua breweries twb muaj ib qho, uas yog ke.
Dab tsi yog cov cua compressors siv hauv cov khoom siv tes ua breweries?Pushs cov kua los ntawm cov kav dej thiab cov tank.Lub zog rau pneumatic conveying thiab tswj.Aeration ntawm wort, poov xab los yog dej.tswj valve.Tshem tawm cov pa roj kom yuam cov av nkos tawm ntawm lub tank thaum ntxuav thiab pab hauv qhov ntxuav.
Ntau daim ntawv thov brewery xav tau kev siv tshwj xeeb ntawm 100% roj-dawb cua compressors.Yog hais tias cov roj tuaj rau hauv kev sib cuag nrog npias, nws tua cov poov xab thiab flattens ua npuas ncauj, uas spoils cov dej haus thiab ua rau npias phem.
Nws kuj yog ib qho kev nyab xeeb.Vim tias kev lag luam khoom noj khoom haus thiab dej haus yog rhiab heev, muaj cov qauv nruj thiab purity nyob rau hauv qhov chaw, thiab yog li ntawd.Piv txwv li: Sullair SRL series roj-dawb cua compressors los ntawm 10 mus rau 15 hp.(los ntawm 7.5 mus rau 11 kW) yog zoo haum rau craft breweries.Breweries txaus siab rau qhov ntsiag to ntawm cov tshuab no.SRL series muaj suab nrov qis qis mus rau 48dBA, ua rau lub compressor haum rau kev siv sab hauv tsev yam tsis muaj chav cais suab.
Thaum huab cua huv yog qhov tseem ceeb, xws li hauv breweries thiab craft breweries, roj tsis muaj huab cua yog qhov tseem ceeb.Cov roj hauv cov cua compressed tuaj yeem paug cov txheej txheem hauv qab thiab ntau lawm.Txij li thaum muaj ntau lub breweries tsim ntau txhiab chim los yog ntau zaus ntawm npias ib xyoos, tsis muaj leej twg muaj peev xwm them taus qhov kev pheej hmoo ntawd.Roj-dawb compressors yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv uas cov huab cua nyob rau hauv kev sib cuag ncaj qha nrog feedstock.Txawm tias nyob rau hauv cov ntawv thov uas tsis muaj kev sib cuag ncaj qha ntawm cov khoom xyaw thiab huab cua, xws li hauv cov kab ntim khoom, cov roj tsis muaj roj compressor pab ua kom cov khoom kawg huv si kom muaj kev thaj yeeb nyab xeeb.
