Cishe ucindezele leyo ngxenye encane esikhwameni sakho sekhofi ukuze unuke ubhontshisi. Kodwa leyo mbobo ayikho lapho yokuhogela khona. Ikhona lapho ngoba ngaphandle kwayo, isikhwama sakho sizoqhuma.
Izikhwama zekhofi zinezivikelo zokukhipha igesi eziya ohlangothini olulodwa ezikhipha i-carbon dioxide ngenkathi zivimba umoya-mpilo. Ubhontshisi othosiwe ukhipha inani elikhulu le-CO2 amahora angama-24-72 ngemva kokuthosa—ukukhululwa okuphezulu kwenzeka lapho izinhlobo eziningi zivala izikhwama zazo. Ivalvu ivimbela ukulimala kwesikhwama phakathi nalesi sikhathi esibucayi, kodwa kuphela uma imininingwane yevalvu ifana neshejuli yakho eqondile yokuthosa nokupakisha kanye nesisindo sokugcwalisa.
Izingxoxo eziningi zokupakisha zigxile ezinhlotsheni zama-valve nezinto zokwakha. Kodwa ngibone ama-valve asezingeni eliphezulu ehluleka ngoba ama-roaster agcwalisa izikhwama emahoreni ayisithupha ngemva kokuwosa esikhundleni seshumi nambili. Umbuzo awukhona ukuthi iyiphi i-valve okufanele isetshenziswe, kodwa ukuthi kufanele ivalwe nini ngemva kokuphola. Qhubeka ufunda ukuze ufunde ukuthi kungani isikhathi sihlala sibaluleke kakhulu kunezincazelo.
Kwenzekani ngempela ngaphakathi kwesikhwama sekhofi esivaliwe?
Ukuthosa kuguqula ubhontshisi wekhofi oluhlaza ngokusebenzisa ukusabela okukhulu kwamakhemikhali. Ukushisa kuphula ama-carbohydrate namaprotheni ayinkimbinkimbi, kukhiqize amakhulu ezinto eziguquguqukayo.
Umkhiqizo oyinhloko olandelanayo yi-carbon dioxide. Ngesikhathi sokubhaka, ubhontshisi ubamba i-CO2 ngaphakathi kwesakhiwo samangqamuzana awo. Uma usususiwe ekushiseni, ubhontshisi uqala ukukhulula le gesi ngokushesha. Izinga lokukhululwa lincike ezingeni lokubhaka kanye nokushisa okuzungezile. Ama-roast amnyama akhipha igesi ngokushesha kune-roast elula, njengoba izinga lokushisa eliphakeme lidala isakhiwo sobhontshisi esinezimbobo eziningi.
Indawo Eyingozi: Amahora angu-24–72
Ubhontshisi osanda kubhakwa ukhipha u-60-80% we-CO2 yawo yonke zingakapheli izinsuku ezintathu. Ukukhishwa komoya ongcolile kufinyelela ezingeni eliphezulu emahoreni okuqala angu-24. Isikhwama esijwayelekile sama-350g sobhontshisi ophelele singadala ingcindezi eyanele yokudabula imithungo noma ukuhlukanisa ifilimu.
Ngibone abarosi belahlekelwa yimikhiqizo yonke ngokunganaki lesi sikhathi. Iklayenti elilodwa livale izikhwama eziyi-1,000 emahoreni amane ngemva korosi, okwaholela ekutheni ama-30% ezikhwama onakale zingakapheli amahora angu-48.
Umthamo wegesi uyahlukahluka kakhulu kuye ngephrofayili yokubhaka:
- •Ukubhaka okulula: ukukhishwa kancane ezinsukwini ezingu-5-7
- •Ukubhaka okuphakathi nendawo: ukukhishwa okuphakathi ezinsukwini ezingu-3-5
- •I-Dark roast: ukukhishwa okuqhumayo emahoreni angama-24-48
Ivalvu yakho kumele ikwazi ukusingatha amazinga okugeleza aphezulu ahambisana nezinga lakho lokubhaka. "Amavalvu ekhofi" ajwayelekile awabaluleki ngalo mehluko.
Kungani umoya-mpilo ulimaza ikhwalithi yekhofi
I-oksijini ibangela ukusabela kwe-oxidation okuphula amakhemikhali anuka kamnandi. Ama-lipids kumafutha ekhofi ayaba bomvu uma evezwa emoyeni. Le nqubo ishesha kakhulu ekushiseni kwegumbi.
Ukweba kuqala zingakapheli amahora ambalwa ngemva kokuchayeka ku-oxygen. Uzobona ukulahlekelwa ukunambitheka ngisho nangaphambi kokuba kuvele isikhunta esibonakalayo. I-valve ayiklanyelwe nje kuphela ukukhulula i-CO2 kodwa futhi nokudala isithiyo esingaseceleni esivimba umoya ozungezile ukuthi ungangeni, kuyilapho ingcindezi yangaphakathi iphoqa igesi ukuthi iphume.
Ukupakishwa kwendabuko okungenamavalvu kuyakuphoqa ukuthi ukhethe: ukuvala ngokushesha bese ubeka engcupheni yokuqhuma, noma ulinde izinsuku ezingu-5-7 ukuze ukhiphe igesi ngokuphelele futhi ulahlekelwe ubusha. Akukho nketho efanele ukusetshenziswa kwezentengiselwano.
Ama-valve okususa igesi ngendlela eyodwa asebenza kanjani?
Indlela yokusebenza yevalvu isebenzisa idiski encane ye-elastomer ecindezelwe esisekelweni esinezimbobo. Ingcindezi yangaphakathi esilinda, ebangelwa ukwakheka kwe-CO2, iphakamisa kancane idiski. Igesi iphuma ezimbobo. Lapho ingcindezi yangaphakathi yehla, idiski ibuyela endaweni yayo yokuqala, ivimba umoya ukuthi ungangeni.
Amavalvu ajwayelekile avuleka ngengcindezi yangaphakathi engu-0.5–1.5 psi. Zivala ngokushesha ngemva kokuba ingcindezi ilingana. Izinto ze-elastomer kumele zihlale ziguquguquka emazingeni okushisa asukela ku--20°F kuya ku-120°F ukuqinisekisa ukuzinza ngesikhathi sokuthuthwa nokugcinwa.
Ukubekwa kwevalvu kubaluleke kakhulu kunalokho ocabanga.
Izinhlobo eziningi zibeka ama-valve noma kuphi ngaphambili kwesikhwama. Kodwa-ke, ukubekwa kwawo kuthinta kakhulu ukusebenza kwawo. Ngihlala ngincoma ukubekwa kwama-valve ngokusekelwe esisindweni sokugcwalisa kanye nokuma kwesikhwama.
Kuma-pouch amile ane-gussets engezansi, i-valve kufanele ibekwe ngaphansi komthungo okungu-2.5-5 cm, okuhlinzeka isikhala esiphezulu sokuqongelela igesi. Izikhwama ezine-gussets eceleni zidinga ama-valve ukuba abekwe phakathi kwephaneli engaphambili ukuze kuvinjelwe ukuguqulwa kobuhle ngenxa yokukhishwa kwe-CO2.
Ukusebenzisana nomkhiqizi wemikhiqizo okhethekile, owasusa ama-valve ngo-7.5 cm ngaphansi kwezikhwama ezinephansi eliyisicaba, kunciphisa izikhalazo zamakhasimende mayelana "nezikhwama ezikhukhumele" ngo-85%.
Ivalvu kumele inikeze izinga lokugeleza elifanele isisindo sokugcwalisa:
- Izikhwama ezingu-8-12 oz: ububanzi bevalvu ejwayelekile bungu-8 mm
- Izikhwama ezingama-1-2 lb: ivalvu engu-10 mm yomthamo omkhulu
- Izikhwama zobhontshisi ezingama-5 lb: uhlelo lwama-valve amabili noma ububanzi obungu-15 mm
Ukusebenzisa amavalvu amancane kudala ingcindezi yangemuva, okwenza kube nzima ukuvala. Amavalvu amakhulu abiza kakhulu kodwa awanikezi ukusebenza okwengeziwe.
Izinkinga Zokuhambisana Nezinto Okungekho Okhuluma Ngazo
Amavalvu anamathiselwa efilimini yokupakisha kusetshenziswa izivalo zokushisa noma isibopho sokunamathela. Isakhiwo sefilimu kumele siqinisekise ukuthi ivalvu iyanamathela ngaphandle kokuhlukanisa. Ngibone amaflaphu ekhipha izikhwama ngoba abakhiqizi basebenzisa izinamathiselo ezingahambisani namafilimu okuvimbela.
Kuma-coffee bag afakwa umquba, ukukhetha ama-valve kubalulekile. Ama-valve endabuko asekelwe ku-PET awawohloki ezindaweni zokwenza umquba. Udinga ama-valve enziwe ngama-polymer afakwa umquba ahlangabezana nezidingo zokusebenzisa kabusha ifilimu yakho.
Imiklamo engasetshenziswa kabusha ibhekene nezinye izinselele. Ivalvu kumele isuswe kalula ngesikhathi sokusetshenziswa kabusha, kungenjalo izongcolisa lonke iqembu. Ngakho-ke, ngincoma ukubeka ivalvu ngendlela yokuthi kube lula kumthengi ukuyisusa ngaphambi kokusetshenziswa kabusha.
Kunini lapho udinga khona ngempela i-valve yokususa igesi?
Ama-capsule asetshenziswa kanye kanye namaphakeji amancane asetshenziswa kanye avame ukungabi nama-valve. Ingqondo icacile: abathengi bapheka le mikhiqizo ngokushesha ngemva kokuvulwa. Isikhathi sokuphila seshelufu silinganiswa ngezinsuku, hhayi amasonto.
Ama-valve ayadingeka uma kuhlangatshezwana nezimo ezintathu: umkhiqizo ubhontshisi ophelele (hhayi oqoshiwe), usayizi wephakheji ungaphezu kwama-ounces angu-8 (230 ml), kanti isikhathi sokuphelelwa yisikhathi esilindelekile singaphezu kwamasonto amabili. Ikhofi eliqoshiwe likhipha ugesi ngokushesha ngo-50% kunobhontshisi ophelele, kodwa ivolumu yegesi iyonke iphansi ngoba inqubo yokugaya ikhipha i-CO2 ebambekile ngaphambi kokupakisha.
Ukunquma Isikhathi Sokuthosa Nokupakisha
Yilapho iningi labarosi lenza khona amaphutha abizayo. Babuza, "Ngingayisebenzisa yiphi ivalvu?" ngaphambi kokuphendula, "Ngingavala nini izikhwama ngemva korosa?"
Uma ungalinda amahora angu-12-24 ngaphambi kokuvala, amavalvu amancane, angabizi kakhulu angasetshenziswa ngoba ukucindezela okuphezulu sekuvele kukhishwe ngokwemvelo. Kodwa-ke, uma udinga ukuvala izikhwama zingakapheli amahora angu-4-6 (okuvamile ekukhiqizweni okukhulu), udinga amavalvu amakhulu aklanyelwe amazinga aphezulu okugeleza.
Ngihlala ngibuza amaklayenti, "Iyini isimiso sakho sangempela sokukhiqiza?" Umrosi ocubungula amaqoqo njalo emahoreni angu-8 udinga isu elihlukile le-valve kunomuntu orosa ikhofi kusukela ngoMsombuluko kuya ngoLwesithathu ukuze lithengiswe emakethe yabalimi ngempelasonto.
Ukubonisana nomuntu othosa i-roaster onciphise izindleko zamavalvu ngo-40% ngokumane alungise izikhathi ze-rack yokupholisa ukuze avumele isikhathi sokuphumula samahora angu-18 ngaphambi kokupakisha.
Izici zezwe kanye nesimo sezulu
Ukuphakama kuthinta izinga lokukhipha igesi. Ubhontshisi obhakiwe endaweni ephakeme ngamamitha ayi-1,500 ukhipha i-CO2 ngokushesha kunalowo obhakiwe endaweni ephansi yolwandle, njengoba ingcindezi ephansi yomoya idala umehluko omkhulu wengcindezi.
Ukushintshashintsha kwezinga lokushisa ngesikhathi sokuthuthwa kuthinta kabi ukuvalwa kwamavalvu. Lapho amaphakheji ethuthwa esuka ezitsheni eziqandisiwe aye ezindaweni zokugcina izinto ezishisayo, kuvela umehluko wokucindezela ongonakalisa ubuqotho bamavalvu. Ngincoma ukuhlola amasampula apakishiwe ngaphansi kwezimo zokujikeleza kwezinga lokushisa ngaphambi kokuqala ukukhiqizwa okukhulu.
Umswakama awuthinti ngqo ukukhishwa kwe-CO2, kodwa uthinta izakhiwo zokuvimbela ifilimu. Umswakama ophezulu ungaholela ekuhlulekeni kokuvala emajoyintini e-valve uma usebenzisa izinamathiseli ezisekelwe emanzini esikhundleni sokuvala ukushisa.
Yimaphi amaphutha amakhulu awenziwa yizinkampani lapho zisebenzisa ama-valve ekhofi?
Iphutha elivame kakhulu ukuphatha wonke ama-valve njengemikhiqizo engashintshaniswayo. Ngibone imikhiqizo ishintsha abaphakeli bama-valve ukuze yonge u-$0.02 ngeyunithi ngayinye, kodwa ilahlekelwe izinkulungwane zamaRandi ngenxa yokuphazamiseka kokupakisha.
Ukusebenza kwevalvu kuncike ezintweni eziyisithupha eziguquguqukayo: iphrofayili yokosa, ubuningi bebhontshisi, isisindo sokugcwalisa, isikhathi sokuvala, izinga lokushisa lokugcina, kanye nesikhathi esilindelekile seshelufu. Ukushintsha noma yikuphi okuguquguqukayo kudinga ukuhlolwa kabusha kokusebenza kwevalvu.
Inganekwane "Yesikhwama Sokuphefumula"
Abanye abarosi benza "izikhwama zokuphefumula" zibe mnandi ngaphandle kokuqonda umthamo wangempela wegesi abawukhiphayo. Ba-oda ama-valve enzelwe itiye noma izinongo—imikhiqizo ekhipha igesi encane—bese bezibuza ukuthi kungani izikhwama zabo zekhofi zisaqhuma.
Ikhofi ikhipha i-CO2 ephindwe ka-5-10 kunekhofi eyomile evamile. Ivalvu yakho kumele imelane nomthamo wangempela olinganisiwe, hhayi izimangalo zokumaketha zokuthi "ikhofi idinga ukuphefumula."
Ngincoma isivivinyo esilula: vala ibhetshi lokuhlola, kala izikhwama lapho upakisha, bese uzikala kabusha ngemva kwamahora angu-24, 48, kanye no-72. Ukwehla kwesisindo kubonisa umthamo we-CO2 okhishwayo. Le datha inquma ngokunembile izinga lokugeleza okufanele ivalvu yakho ibhekane nalo.
Ukungazinaki Izinguquko Emnothweni Wokubhalisa
Imakethe iyahlukana, isuka ekuthengeni ngobuningi iye ekulethweni kokubhalisa okuncane nokuvama kakhulu. Lokhu kushintsha ngokuphelele ukwakheka kokupakisha okuhle kakhulu.
Ama-roaster e-micro-batch manje adinga izinhlelo zama-valve ezingavalwa kabusha ngoba abathengi bafuna izikhwama ezingama-ounces angu-8 abangadla zingakapheli izinsuku ezingu-5-7, hhayi izikhwama ezingama-pound angu-2 ezihlala zivuliwe amasonto. Kodwa-ke, abakhiqizi abaningi basasebenzisa ama-valve endabuko aqondene nemodeli endala yokuthengisa.
Ukuthuthukisa izikhwama ezivuselelwa ngokwezifiso ngesistimu yokukhipha igesi eyakhelwe ngaphakathi yezinkampani ezibhaliselayo kuvumela amakhasimende ukuthi alondoloze ubusha ngemva kokuvulwa okuphindaphindiwe ngenkathi elawula ukukhishwa kwe-CO2 okuvela ezikhwameni ezisetshenziswe kancane.
Indlela Yokukhetha I-Valve Efanele Yokupakisha Ikhofi
Qala ngokunquma isikhathi kusukela ekuthoseni kuya ekupakisheni. Linganisa kahle—hhayi uma ufuna ukuvala ikhofi, kodwa uma ulivala ngempela ngaphansi kwezimo ezijwayelekile zokukhiqiza.
Uma kudingeka ukuvala zingakapheli amahora ayi-6 kusukela ekuthoseni, chaza ama-valve ageleza kakhulu (ububanzi obuyi-10 mm noma ngaphezulu) alinganiswe ngokwehluka kokucindezela okungu-2 psi noma ngaphezulu. Uma kudingeka ukuvala zingakapheli amahora ayi-12-24, ama-valve ajwayelekile angu-8 mm ububanzi azofaneleka ezinhlelweni eziningi. Uma kudingeka ukuvala amahora angama-48 noma ngaphezulu, cabanga ukuthi uyayidinga yini i-valve yamaphakheji angaphansi kwama-ounces ayi-12.
