Ikawa irashobora gupakirwa idafite indangagaciro?

Kubungabunga agashya kawa yabo ikaranze nikibazo gikomeye kubikawa.Indangantego ya degassing nigikoresho cyingenzi mugukora ibi.

Umuyoboro wangiza, watanzwe mu 1960, ni umushinga umwe utuma ibishyimbo bya kawa birekura buhoro buhoro imyuka nka gaze karuboni (CO2) idahuye na ogisijeni.

Imyanda itesha agaciro, isa nkibikoresho byoroshye bya pulasitike, ni ibicuruzwa bishimwa cyane bituma ikawa ikaranze ikora urugendo rurerure itiriwe yangirika.

Ariko, kwinjizwa mu gupakira ikawa irambye birashobora kuba ikibazo kuko bigomba kuvaho kenshi mbere yo kujugunywa.Nkigisubizo, abatekamutwe bamwe bashobora gukoresha imifuka idafite agaciro keza niba ikawa yabo izatangwa nyuma yo kotsa.

Komeza usome kugirango umenye byinshi kubyerekeranye na devassing valve nibindi bisobanuro bigera kuri roaster.

Niyihe ntego ya valve itesha agaciro?

Ikawa yerekana impinduka nini zumubiri iyo zokejwe, hamwe nubunini bwazo bwiyongera kugera kuri 80%.

Byongeye kandi, gutwika birekura imyuka ifashe mu bishyimbo, hafi 78% muri yo ni dioxyde de carbone (CO2).

Gutesha agaciro bibaho mugihe cyo gupakira, gusya, no kunywa ikawa.Kubunini buke, buringaniye, kandi bwiza bwo gusya, urugero, 26% na 59% bya CO2 muri kawa irekurwa nyuma yo gusya.

Mugihe kuba CO2 isanzwe yerekana gushya, irashobora kugira ingaruka mbi kuburyohe n'impumuro ya kawa.Kurugero, ikawa itahawe umwanya uhagije kuri degas irashobora kubyara ibibyimba mugihe cyo guteka, bikavamo gukuramo bidahuye.

Gutesha agaciro bigomba gucungwa neza kuko ibyinshi muri byo bishobora gutera ikawa guhagarara.Nyamara, degassing idahagije irashobora kugira ingaruka kuburyo ikawa ikuramo kandi ikora crema.

Roaster yavumbuye ingamba nyinshi zo kugenzura inzira yo gutesha agaciro mugihe ukoresheje ikosa namakosa.

Gukoresha ibipfunyika bikomeye bishobora kwihanganira umuvuduko wo gukusanya CO2 cyangwa kwemerera ikawa degas mbere yo gupakira byombi byakoreshejwe nkibisubizo byashize.Bagerageje kandi ikawa ifunga vacuum mugihe yari ikiri muri kontineri yayo.

Ariko, buri buryo bwari bufite ingaruka.Kurugero, byafashe igihe kinini kugirango ikawa igabanuke, yerekanaga ibishyimbo okiside.Gupakira ibintu bikomeye, byari bihenze kandi bigoye kwimuka.

Ibice byinshi byimpumuro nziza yikawa byavanyweho mugihe cyo gufunga vacuum, byagize ingaruka mbi kumiterere yacyo.

Umuyoboro wa degassing wavumbuwe mu myaka ya za 1960 na sosiyete itunganya ibicuruzwa byo mu Butaliyani Goglio, ari naho byahindutse.

Umuyoboro wangirika uracyari umwe muri iki gihe kandi ugizwe na diafragm ya reberi imbere yatewe inshinge.Ubusumbane bwubuso burwanya umubiri wa valve bugumishwa nigice cyamazi kiri imbere imbere ya valve.

Amazi aranyerera kandi yimura diaphragm mugihe itandukaniro ryumuvuduko rigeze kumurongo.Ibi bituma bishoboka ko gaze ishobora guhunga mugihe ogisijeni itabitswe.

Gutesha agaciro indangantego

Hariho impamvu nyinshi zituma abatekamutwe bashobora gufata icyemezo cyo kwirinda gukoresha indangagaciro zangiza, nubwo bahinduye uburyo ikawa ipakirwa.

Ingaruka igaragara cyane nuko izamura igiciro cyo gupakira.Roaster zimwe na zimwe zifite impungenge ko valve yihutisha gutakaza aromatics.Bavumbuye ko gufunga umufuka udafite valve bishobora gutera kubyuka no kwaguka ariko ntibitere guturika.

Kubera iyo mpamvu, aba roaster bakunze gufata icyemezo cyo guhagarika ikawa yabo aho.

Kutamenya neza niba indangagaciro za degassing zishobora gukoreshwa ni ikindi kibazo nabo.

Hano hari amakuru make aboneka kubutandukane bukwiye no gutunganya ibyangiritse.Bitewe no gucapisha gake amabwiriza ya recycling amabwiriza yo gupakira ikawa, igice kinini cyubwumvikane buke bwimuriwe kubakiriya.

Abaguzi bagenda barushaho kumenya uburyo ibyo bagura bigira ingaruka kubidukikije.Nkigisubizo, barashobora guhitamo ikawa itandukanye niba paki idafite amakuru yo gutunganya.

Roaster irashobora guhitamo indangagaciro zishobora gukoreshwa kumifuka yikawa nkigisubizo.Ibi birashobora kwinjizwa byihuse kandi neza mubipfunyika, kandi bimwe muribi birashobora gukoresha plastike nkeya 90%.

Nkubundi buryo, indangagaciro zimwe zangiza zakozwe muri bioplastique nka acide polylactique, zihendutse cyane kuri roaster kandi zangiza ibidukikije.

Itumanaho ryamabwiriza yo kujugunya valve, nkuburyo ishobora gukurwaho kugirango itunganyirizwe, kubipakira ikawa ningirakamaro mugihe ukoresheje aya mahitamo.

Birakenewe gushyiramo indangagaciro za degassing kuri buri gapaki kawa?

Ibintu byinshi bishobora guhindura amahitamo ya roaster kugirango akoreshe valve itesha agaciro.Ibi birimo ibiranga kotsa kandi niba ikawa igurishwa ibishyimbo cyangwa ubutaka.

Icyotsa cyijimye, kurugero, gikunda kwangirika vuba kuruta kotsa yoroheje, mugihe ufite gaze nini.Ibi biterwa nuko imiterere yibishyimbo igenda iba myinshi kuko bamara igihe kinini muri roaster.

Roaster igomba kubanza kwiga abakiriya babo akamenyero ko gukoresha.Ibi bizafasha mukugereranya ingano ya kawa ipakiye kimwe nubunini bukenewe.

Iyo ikawa igurishijwe ku rugero ruto, mubisanzwe ntabwo iba ifite umwanya uhagije wo gutera ingorane zo gupakira mugihe habuze valve yangiza.Abakiriya bazarya ikawa byihuse kuruta uko bari bafite byinshi, nk'imifuka 1kg.

Mu bihe nk'ibi, abatekamutwe barashobora guhitamo kugurisha abakiriya ba kawa nkeya.

Hariho uburyo bwo kwirinda okiside ya roaster idakoresha indangagaciro za degassing.Kuzunguza azote, kurugero, bikoreshwa na roaster zimwe, mugihe izindi zirimo ogisijeni na CO2 zinjiza amasaketi mubipfunyika.

Roaster irashobora kandi kwemeza ko uburyo bwo gufunga ibipfunyika ari umuyaga mwinshi bishoboka.Gufunga zip, kurugero, birashobora kuba byiza kuruta karuvati yo kubuza ogisijeni kwinjira mumifuka yikawa.

Kimwe mu bikoresho bitandukanye biboneka kuri roaster kugirango umenye neza ko ikawa yabo igezwa kubakiriya bameze neza ni ugutesha agaciro.

Niba abatekamutwe bahisemo gukoresha valve itesha agaciro, gukorana ninzobere mu gupakira ibintu bishobora gufasha kugumana imiterere yikawa kandi bigatuma abaguzi bagaruka kubindi byinshi.

Imyanda itesha agaciro ishobora gukoreshwa rwose kandi idafite BPA iraboneka muri Cyan Pak kandi irashobora gutunganywa hamwe nibindi bipakira ikawa.Igifuniko, disiki ya elastike, igicucu cyiza, isahani ya polyethylene, hamwe nayunguruzo rwimpapuro nibintu bisanzwe bigize iyi mibande.

Ntabwo zifasha gusa gukora ibicuruzwa abaguzi bashobora gukoresha byoroshye, ariko kandi bigabanya ingaruka mbi ibyo gupakira ikawa bigira kubidukikije.

Kugirango tuguhe ubundi buryo bwo gukomeza ikawa yawe nshya, dushyiramo kandi ziplock, velcro zippers, amabati, hamwe na rip.

Abakiriya barashobora kuba bazi neza ko paki yawe idafite tamper kandi nkibishya bishobotse ukoresheje rip not na velcro zippers, zitanga ibyiringiro byo kumva gufunga byimazeyo.Ibipapuro byacu byo hasi birashobora gukora neza hamwe namabati kugirango tugumane uburinganire bwimiterere yipakira.
