Umuyoboro umwe wo guhanahana gaze, wavumbuwe mu myaka ya za 1960, wahinduye burundu gupakira ikawa.
Mbere yo kurema, byari bigoye kubika ikawa mubipfunyika byoroshye.Impanuka zo kumanura zabonye izina ryintwari itamenyekanye mubijyanye no gupakira ikawa.
Imyanda itesha agaciro yatumye bishoboka ko abatekamutwe batwara ibicuruzwa byabo kure kuruta mbere mu gihe bifasha abaguzi gukomeza ikawa yabo igihe kirekire.
Inzobere nyinshi zidasanzwe zahujije ibishushanyo mbonera bya kawa kugirango bishyiremo ipaki yikawa yoroheje hamwe na valve ya degassing ihuriweho, kandi bimaze kuba ihame.
Tumaze kuvuga ko, indangagaciro zitesha agaciro zigomba gushyirwaho hejuru yikawawa kugirango ikoreshwe?
Nigute imifuka yikawa ya 'degassing valves ikora?
Gutesha agaciro indangagaciro zikora nkuburyo bumwe bwo kureka imyuka ikava aho bahoze.
Imyuka iva mubicuruzwa bipfunyitse ikenera inzira yo guhungira ahantu hafunzwe hatabangamiye ubusugire bwumufuka.
Ijambo "out-gassing" na "off-gassing" rikoreshwa kenshi muburyo bumwe bwo gutesha agaciro ubucuruzi bwa kawa.
Gutesha agaciro ni uburyo ikawa ikaranze ikaranze irekura karuboni ya dioxyde yari yarinjijwe mbere.
Ariko, hariho itandukaniro rinini hagati yo gusohora no gutesha agaciro mumagambo afatika ya chimie, cyane cyane geochemie.
Gusohora gaze nijambo rikoreshwa mugusobanura kwirukana gaze kwizana kandi karemano mumazu yabanje gukomera cyangwa mumazi aho leta ihinduka.
Nubwo gutesha agaciro byerekana uruhare rwabantu mugutandukanya imyuka yasohotse, ntabwo buri gihe aribyo.
Imyanda isohora imyuka hamwe na valise itesha agaciro akenshi bifite igishushanyo kimwe, ikagura iri jambo risobanura itandukaniro ryikawa.
Ibi ni ukugira ngo guhanahana gaze bishobora kubaho mugihe igikapu cya kawa gikubiswe kugirango biteze imbere guhanahana gaze cyangwa mubisanzwe bibaho hamwe nibidukikije byo hanze.
Igifuniko, disiki ya elastike, igicucu cyinshi, isahani ya polyethylene, hamwe nayunguruzo rwimpapuro nibintu bisanzwe bigize imyanda.
Umuyoboro urimo diaphragm ya reberi ifite ibara ryinshi ryamazi ya kashe imbere, cyangwa ikawa ireba ikawa.Ibi bikomeza guhagarika ubuso burwanya valve ihoraho.
Ikawa irekura CO2 uko igabanuka, ikongera umuvuduko.Amazi azasunika diafragma ahantu hatariho umuvuduko uri mumifuka yikawa ikaranze irenze hejuru yubuso, bigatuma CO2 yinyongera ihunga.
Ese indangagaciro za degassing zirakenewe mugupakira ikawa?
Impanuka zo kumanura nikintu cyingenzi cyimifuka yikawa ifite igishushanyo cyiza.
Imyuka irashobora kwirundanyiriza mumwanya wumuvuduko niba itashyizwe mubipfunyika bigenewe ikawa ikaranze.
Byongeye kandi, ibipfunyika birashobora gushwanyagurika cyangwa kubangamira ubusugire bwikofi yikawa bitewe nubwoko nibiranga ibikoresho.
Carbohydrates igoye igabanyijemo mo molekile ntoya, yoroshye mugihe cyo gutwika ikawa yicyatsi, kandi amazi na karuboni byombi biremwa.
Mubyukuri, kurekura byihuse bimwe muribi byuka nubushuhe nibyo bitera "icyambere cyambere" kizwi cyane ba roaster benshi bakoresha mukugenzura no gucunga ibiranga bikaranze.
Nyamara, nyuma yo guturika kwambere, imyuka ikomeza gukora kandi ntigisohoka rwose kugeza muminsi mike nyuma yo gutwika.Iyi gaze isaba aho ijya kuko ihora isohoka mubishyimbo bya kawa ikaranze.
Ikawa ikaranze neza ntishobora kwemerwa kumufuka wa kawa ufunze udafite valve kugirango uhunge gaze neza.
Iyo ikawa iri hasi kandi igitonyanga cyambere cyamazi kongewe mumasafuriya yo guteka, zimwe muri dioxyde de carbone yakozwe mugihe cyo kotsa zizaba zikiri mubishyimbo kandi zizirukanwa.
Iri shurwe, riboneka mu binyobwa bisukuye, akenshi ni ikimenyetso cyizewe cyerekana uburyo ikawa iherutse gutekwa.
Kimwe n’imifuka yikawa, dioxyde de carbone nkeya mumutwe irashobora gufasha mukwongerera igihe cyo guhagarika umwuka wa ogisijeni wangiza mukirere gikikije.Nyamara, kwiyongera kwa gaze birashobora gutuma ibipfunyika biturika.
Nibyingenzi kubakariso kuzirikana igihe valve ikoreshwa mugupakira ikawa izamara.Amahitamo yo kurangiza ubuzima-nyuma yumukoresha arangije gukoresha ibicuruzwa bishobora guterwa nibintu bitandukanye.
Byaba byiza impanvu zimeze kimwe niba, nkurugero, imifuka yikawa ya kawa ikozwe mu nganda.
Ubundi buryo ni ugukoresha valve itesha agaciro ishobora gukoreshwa.Ni ngombwa kumenya ko hamwe naya mahitamo, abakoresha basabwa kuvanaho valve mumapaki hanyuma bakayijugunya ukwayo.
Niba ibikoresho byo gupakira bishobora gutabwa hamwe nimbaraga nke zumuguzi kandi, nibyiza, nkigice kimwe, akenshi usanga bafite amahirwe menshi yo kuba ingaruzwamuheto.
Hano hari amahitamo menshi kubidukikije byangiza ibidukikije.Imyanda ishobora kwangirika itanga ibintu bimwe na plastiki bitagira ingaruka mbi ku bidukikije kuva byakozwe hakoreshejwe bioplastique yatewe inshinge ikomoka ku mutungo ushobora kuvugururwa, nk'ibihingwa.
Kugirango wizere ko gupakira bigera mubikoresho bikwiye, abatekamutwe bagomba kwibuka kwibutsa abakiriya uburyo bwo guta imifuka yikawa yataye.
Nihehe mubipfunyika ikawa bigomba gushyirwaho indangagaciro?
Yaba pouches ihagaze cyangwa imifuka kuruhande-gusseted, gupakira byoroshye byagaragaye nkisoko ryahisemo isoko yo gupakira ikawa.
Kugabanura indangagaciro biragaragara ko ari ngombwa kugirango ubungabunge uburinganire bwibishyimbo bya kawa bishya bikaranze nkuko babikora.
Ahantu nyaburanga, ariko, hagomba kwitabwaho.
Roaster irashobora guhitamo gushiraho valve muburyo butagaragara cyangwa ahantu huzuza isura yibirango byabo, ukurikije ibyiza byabo.
Nubwo gushyira valve bishobora guhinduka, ibibanza byose byaremwe bingana?
Umuyoboro wa degassing ugomba kuba uri mumutwe wumufuka kugirango ukore neza kuko hano niho imyuka myinshi yasohotse izakusanyiriza.
Imiterere yimifuka yikawa nayo igomba kwitabwaho.Ikibanza cyo hagati nicyiza kuva gishyize valve hafi yicyuma gishobora guca intege gupakira.
Nubwo bimeze bityo ariko, hari ibyo uhindura ukurikije aho abatekamutwe bashobora gushyira valve itesha agaciro, cyane cyane kumurongo wo hagati, hafi yipakira.
Nubwo ibikoresho byo gupakira bikora byumvikana ko bifite intego yihariye kubakoresha ibidukikije byiki gihe, igishushanyo mbonera kiracyafite uruhare runini mugugura ibyemezo.
Nubwo bishobora kugorana, indangagaciro zitesha agaciro ntizigomba kwirengagizwa mugushushanya ibihangano kumifuka yikawa.
Kuri Cyan Pak, duha abatekamutwe guhitamo hagati ya classique ya classique imwe yo kwangirika hamwe na 100% byongeye gukoreshwa, BPA idafite agaciro ka BPA kumifuka yabo yikawa.
Indangantego zacu zirahinduka, zoroheje, kandi zihendutse, kandi zirashobora gukoreshwa hamwe nuburyo bwo guhitamo ikawa yangiza ibidukikije.
Roaster irashobora guhitamo mubikoresho bitandukanye byongera gukoreshwa bigabanya imyanda kandi bigashyigikira ubukungu bwizunguruka, harimo impapuro zubukorikori, impapuro z'umuceri, hamwe nububiko bwa LDPE butandukanye hamwe nibidukikije byangiza ibidukikije imbere muri PLA.
Byongeye kandi, kubera ko dukoresha ikoranabuhanga rigezweho ryo gucapa ibyuma bya digitale, umurongo wose wapakira ikawa birashoboka rwose.Ibi bidushoboza kuguha umwanya wihuse wamasaha 40 nigihe cyo kohereza amasaha 24.
