Ese ibishyimbo bya kawa bikaranze bishobora gutekwa ako kanya? Yego, ariko ntabwo ari ngombwa ko biryoha. Ibishyimbo bya kawa bikaranze bishya bizagira igihe cyo gukura ibishyimbo, ari cyo gusohora dioxyde de carbone no kugera ku gihe cyiza cy'uburyohe bwa kawa. None se tubika gute ikawa? Kugira ngo tubike ibishyimbo bya kawa, dutekereza gukoresha imifuka ya kawa ku nshuro ya mbere, ariko se wigeze witegereza neza imifuka ya kawa? Wigeze ubona valve y'umweru cyangwa isobanutse inyuma cyangwa imbere mu mufuka wa kawa? Cyangwa warabibonye ntubyiteho? Ntugatekereze ko iyi valve ikoreshwa iyo ubonye valve ari nto. Mu by'ukuri, valve nto ni ibanga ry' "ubuzima cyangwa urupfu" rw'ibishyimbo bya kawa.
Iyi valve niyo twita "valve isohora umwuka wa kawa", kandi yitwa valve isohora umwuka wa rimwe. Valve isohora umwuka wa rimwe igira uruhare runini mu gufasha ikawa yawe nshya kuguma ari nshya igihe kirekire. Valve isohora umwuka wa rimwe iri mu gikapu cy'ibishyimbo bya kawa ni ikintu gifasha mu gikapu gukumira umwuka usubira inyuma. Incamake y'iyi valve isohora umwuka wa rimwe ifite imirimo ibiri, imwe ni ugusohora umwuka uri mu gikapu, indi ni ugutandukanya umwuka uri hanze y'igikapu cyo gupakira winjire. Hanyuma, valve ifata ya Wo izagaragaza iyi mirimo ibiri n'uko ikora.
1. Imoshi isohora umwuka,
Ibishyimbo bya kawa kibisi birimo aside, poroteyine, esters, karubohidrati, amazi na kafeyine. Nyuma y’uko ibishyimbo bya kawa kibisi bikaranze ku bushyuhe bwinshi, karubohidrati ikorwa binyuze mu buryo butandukanye bw’ibinyabutabire nka Maillard reaction. Muri rusange, karubohidrati n’indi myuka ihinduka iva mu bishyimbo bya kawa bikaranze bigira 2% by’uburemere bw’ibishyimbo byose bya kawa. Kandi 2% bya kawa irekurwa buhoro buhoro mu miterere ya fibre y’ibishyimbo, kandi igihe cyo kubisohora kizaterwa n’uburyo bwo kubiteka. Kubera ko ibishyimbo bya kawa bisohora karubohidrati ubwabyo, tuzabona ibishyimbo bya kawa bikaranze mu gikapu gifunze kizabyimba uko igihe kigenda gihita. Iki ni cyo cyitwa "igikapu cyuzuye". Hamwe n’agakoresho ko gusohora umwuka k’inzira imwe, bizafasha gukuraho iyi myuka idakora mu gikapu ku gihe, kugira ngo iyi myuka idakora ku bishyimbo bya kawa kandi ikomeze kuba mishya ku bishyimbo bya kawa.
2.tandukanya umwuka,
Ni gute watandukanya umwuka mu gihe uwukoresha? Valve y'icyerekezo kimwe itandukanye na valve isanzwe y'umwuka. Iyo hakoreshejwe valve isanzwe y'umwuka, mu gihe gazi iri mu gikapu cyo gupakira isohoka, bizatuma umwuka uri hanze y'umukandara wo gupakira ujya mu gikapu, ibyo bikangiza imikorere yo gufunga umufuka wo gupakira kandi bigatuma ikawa ikomeza gushonga. Oxidation y'ibishyimbo bya kawa itera impumuro mbi no kwangirika kw'imiterere. Valve y'icyerekezo kimwe ntikora, isohora dioxyde de carbone mu gikapu ku gihe, kandi ntiyemerera umwuka wo hanze kwinjira mu gikapu. None se, ni gute ishobora kubuza umwuka wo hanze kwinjira mu gikapu? Valve yo kwinjira ya Wo ikubwira ihame ryayo: iyo umuvuduko w'umwuka mu gikapu ugeze ku rugero runaka, valve ya valve yo gusohora umwuka y'icyerekezo kimwe irakinguka kugira ngo irekure umwuka mu gikapu; kugeza igihe umuvuduko w'umwuka umanuka munsi y'urwego rwa valve yo mu cyerekezo kimwe. Valve y'icyerekezo kimwe irafungwa, kandi agakapu ko gupakira gasubira mu buryo bufunze.
Kubwibyo, twasanze ko uburyo bwo gushyira imyuka ya kawa mu cyerekezo kimwe ari bwo bukenewe cyane, kandi ni nabwo bukenewe cyane. Iyo ibishyimbo bya kawa bikaranze cyane, ingaruka z'imyuka zizaba zikomeye, kandi dioxyde de carbone izarekurwa vuba.
