Kuki ingano yikawa ari ngombwa?

Ku bijyanye no gupakira ikawa, isake yihariye igomba gusuzuma ibintu bitandukanye, uhereye kumabara, imiterere kugeza kubikoresho nibindi bikoresho.Ariko, ikintu kimwe rimwe na rimwe kitubahirizwa ni ubunini.

Ingano yipakira irashobora kugira ingaruka zikomeye ntabwo ari nziza yikawa gusa, ahubwo no mubiranga umwihariko nk'impumuro nziza n'inoti.Ingano yumwanya ukikije ikawa iyo ipakiwe, izwi kandi nka "umutwe wumutwe," ni ingenzi kuri ibi.

Hugh Kelly, Umuyobozi ushinzwe Amahugurwa muri ONA Coffee ikorera muri Ositaraliya ndetse n’umukinnyi wanyuma wa Shampiyona y’isi ya Barista 2017, yambwiye akamaro k’ubunini bwa kawa.

Umwanya w'umutwe ni iki kandi bigira izihe ngaruka ku gushya?

Usibye ikawa yuzuye vacuum, ubwinshi mubipakira byoroshye bifite ahantu huzuye umwuka wuzuye hejuru yibicuruzwa bizwi nka "umutwe wumutwe."

Umwanya wumutwe ningirakamaro mukubungabunga agashya no kugumana imiterere yikawa, ndetse no kurinda ikawa mukora umusego uzengurutse ibishyimbo.Hugh Kelly, Nyampinga wa Barista inshuro eshatu muri Ositaraliya, agira ati: "Roaster igomba kumenya buri gihe umwanya uri hejuru yikawa iri mu gikapu."

Ibi biterwa no kurekura karuboni (CO2).Iyo ikawa ikaranze, CO2 irundanya mumiterere yibishyimbo mbere yo guhunga buhoro buhoro muminsi mike nibyumweru biri imbere.Ingano ya CO2 muri kawa irashobora guhindura ibintu byose kuva impumuro nziza kugeza inoti.

Iyo ikawa ipakiwe, bisaba icyumba runaka kugirango CO2 yarekuwe ikemuke kandi itange umwuka ukungahaye kuri karubone.Ibi bifasha kugumya umuvuduko uri hagati yibishyimbo numwuka uri mumufuka uhagaze neza, birinda gukwirakwizwa kwinshi.

Niba CO2 yose iramutse ihunze gitunguranye mumufuka, ikawa yangirika vuba kandi ubuzima bwayo bukagabanuka cyane.

Ariko, hari ahantu heza.Hugh araganira kuri zimwe mu mpinduka zishobora kugaragara mu miterere ya kawa mugihe umwanya wa kontineri ari muto cyane: “Niba umutwe w’umutwe ukabije kandi gaze iva mu ikawa ikomatanyirijwe cyane ku bishyimbo, birashobora kugira ingaruka mbi ku bwiza bwa ikawa, ”abisobanura.

“Irashobora gutuma ikawa iryoshe kandi rimwe na rimwe ikagira umwotsi muke.”Icyakora, bimwe muribi bishobora guterwa numwirondoro ukaranze, kuko urumuri rworoshye kandi rwihuse rushobora kubyitwaramo ukundi. ”

Igipimo cyo gutesha agaciro nacyo gishobora guterwa numuvuduko wo kotsa.Ikawa yatetse vuba ikunda kugumana CO2 nyinshi kuko ifite igihe gito cyo guhunga mugihe cyose cyo gutwika.

Niki gihinduka uko umutwe wagutse?

Mubisanzwe, umwanya wumutwe mubipfunyika uzaguka mugihe abakiriya banywa ikawa yabo.Iyo ibi bibaye, gaze yinyongera iva mubishyimbo ireka gukwirakwira mu kirere gikikije.

Hugh agira inama abantu kugabanya umutwe mugihe banywa ikawa yabo kugirango babungabunge agashya.

Avuga ati: “Abaguzi bakeneye gutekereza ku mutwe.Ati: "Bakeneye kugabanya umwanya wumutwe kugirango birinde gukomeza gukwirakwira, keretse ikawa ari shyashya kandi ikarema CO2 nyinshi.Kugirango ubigereho, shyira umufuka kandi urinde umutekano ukoresheje kaseti.

Ku rundi ruhande, niba ikawa ari shyashya cyane, nibyiza kwirinda kugabanya cyane umufuka mugihe abayikoresha bayifunze kuko gaze imwe iracyasaba umwanya wo kujyamo iyo irekuwe mubishyimbo.

Byongeye kandi, kugabanya umwanya wumutwe bifasha kugabanya urugero rwa ogisijeni mumufuka.Umwuka wa ogisijeni winjira mu gikapu igihe cyose ufunguye ushobora gutera ikawa gutakaza impumuro nziza n'imyaka.Igabanya amahirwe ya okiside mukanda igikapu no kugabanya umwuka ukikije ikawa.

Guhitamo ingano yububiko bwa kawa yawe

Nibyingenzi kubakoresha umwihariko kugirango bamenye neza ko umwanya wibipfunyika byombi ari bito bihagije kugirango bigumane gushya kandi binini bihagije kugirango wirinde guhindura ibiranga ikawa.

Mu gihe nta mabwiriza akomeye kandi yihuse y’umwanya wa kawa igomba kuba ifite, nk'uko Hugh abitangaza, roaster ishinzwe gukora ibizamini kugira ngo hamenyekane icyakorwa kuri buri bicuruzwa byabo.

Uburyo bwonyine bwo kotsa kugirango bamenye niba ingano yumutwe ikwiranye nikawa yabo ni ugukora uburyohe ku rundi, nkuko abivuga.Buri roaster yihatira kubyara ikawa ifite umwirondoro udasanzwe, gukuramo, nimbaraga.

Mu gusoza, uburemere bwibishyimbo bufashwe imbere bugena ingano yipakira.Ibipaki binini, nkibice byo hasi cyangwa kuruhande gusset pouches, birashobora gukenerwa kubwinshi bwibishyimbo kubaguzi benshi.

Gucuruza ibishyimbo bya kawa mubisanzwe bipima 250g kubakoresha urugo, kubwibyo guhagarara cyangwa ibikapu bya kashe birashobora kuba byiza.

Hugh atanga inama ko kongeramo umwanya munini “bishobora… kuba [ingirakamaro] kuko bizorohereza [ikawa] niba ufite ikawa iremereye [ifite umwijima].”

Umwanya munini w’umutwe, urashobora kwangiza mugihe upakiye urumuri cyangwa urumuri ruciriritse, nkuko Hugh abivuga, "Bishobora gutuma [ikawa] isaza… vuba."

Impanuka zo kumanura zigomba kongerwaho kumasawa nayo.Umuyaga umwe-umwe witwa degassing valves urashobora kongerwaho muburyo ubwo aribwo bwose bwo gupakira mugihe cyangwa nyuma yumusaruro.Zirinda ogisijeni kwinjira mu gikapu mu gihe zemerera CO2 zegeranijwe guhunga.

Nubwo ari ibintu bikunze kwirengagizwa, ingano yipakira ningirakamaro mugukomeza gushya hamwe nimico idasanzwe yikawa.Ikawa izahinduka niba hari umwanya munini cyangwa muto cyane hagati yibishyimbo no gupakira, bishobora no kuvamo uburyohe "buremereye".

Kuri Cyan Pak, tuzi ko ari ngombwa ko abatekamutwe badasanzwe baha abakiriya babo ikawa nziza.Turashobora kugufasha kubaka igipimo cyiza-cyiza cya kawa yawe, yaba ibishyimbo cyangwa ubutaka bwose, tubifashijwemo na serivise zacu zubuhanga zubuhanga hamwe nubundi buryo bushobora guhinduka.Dutanga kandi BPA-yubusa, isubirwamo rwose ya degassing ya valve ikwiranye neza imbere mumifuka.

Twandikire kugirango umenye byinshi kubyerekeye gupakira ikawa yangiza ibidukikije.
