Ukugcinwa kokutsha kwekofu yabo egcadiweyo ngumba obalulekileyo kwabo barosa ikofu.Ivalve yokukhupha umoya sisixhobo esibalulekileyo ekwenzeni oku.
Ivalve yokukhupha amanzi, eyayinelungelo elilodwa lomenzi ngo-1960, yindlela enye evumela iimbotyi zekofu ukuba zikhuphe ngobunono iigesi ezifana nekhabhon diokside (CO2) ngaphandle kokudibana neoksijini.
Iivalvu zokukhupha amanzi, ezibonakala ziyimilomo yeplastiki elula, zizinto ezixatyiswa kakhulu ezivumela ikofu egcadiweyo ukuba ihambe imigama emide ngaphandle kokwenzakala.
Nangona kunjalo, ukufakwa kwabo kwipakethe yekofu ezinzileyo kunokuba yingxaki kuba kufuneka basuswe rhoqo ngaphambi kokulahlwa.Ngenxa yoko, abanye abatshisi banokusebenzisa iibhegi ngaphandle kweevalve zokukhupha i-degassing ukuba ikofu yabo iya kunikwa kungekudala emva kokugcadwa.
Qhubeka ufunda ukuze ufunde ngakumbi malunga neevalvu zokukhupha igesi kunye nezinye iindlela ezifikelelekayo kwii-roasters.
Yintoni injongo yesivalo sokukhupha umoya?
Ikofu ibonisa utshintsho olukhulu emzimbeni xa yosiwe, nomthamo wayo unyuka ukuya kuthi ga kwi-80%.
Ngaphaya koko, ukuqhotsa kukhupha iigesi ezigcinwe kwimbotyi, malunga ne-78% yazo yicarbon dioxide (CO2).
I-degassing iyenzeka ngexesha lokupakishwa, ukugaya, kunye nokusela ikofu.Ubukhulu be-coarse, medium, and fine grind sizes, umzekelo, i-26% kunye ne-59% ye-CO2 kwikofu ikhutshwe emva kokugaya, ngokulandelanayo.
Ngelixa ubukho be-CO2 buhlala bubonisa ubutsha, bunokuba nefuthe elibi kwincasa kunye nevumba lekofu.Ngokomzekelo, ikofu engakhange inikwe ixesha elaneleyo kwi-degas inokuvelisa ama-bubbles ngexesha lokusela, okukhokelela ekutsalweni okungaguqukiyo.
I-Degassing kufuneka ilawulwe ngononophelo kuba uninzi lwayo lunokubangela ukuba ikofu iphelelwe lixesha.Nangona kunjalo, i-degassing engonelanga inokuchaphazela indlela i-coffee extracts kunye ne-crema ngayo.
Iiroasters zifumene iindlela ezininzi zokulawula inkqubo yokukhupha igesi ngokuhamba kwexesha ngolingo nangempazamo.
Ukusetyenziswa kweepakethe eziqinileyo ezinokumelana noxinzelelo lwe-CO2 yokuqokelela okanye ukuvumela ikhofi ukuba i-degas ngaphambi kokupakisha zombini isetyenziswe njengezisombululo kwixesha elidlulileyo.Baphinde bavavanya ikofu evacuum-vacuum ngelixa ikwisikhongozeli sayo.
Noko ke, indlela nganye yokufundisa yayineengxaki.Ngokomzekelo, kuthathe ixesha elide ukuba ikofu ibe yi-degas, ebeka iimbotyi kwi-oxidation.Ukupakisha okuqinileyo, kwelinye icala, kwakubiza kwaye kunzima ukuhamba.
Amacandelo amaninzi evumba eliguquguqukayo ekofu apheliswa ngexesha lokutywinwa kwe-vacuum, eyaba nefuthe elibi kwiimpawu zayo zokuva.
Ivalve yokukhupha amanzi yaqanjwa ngoo-1960 yinkampani yase-Italiya yokupakisha iGoglio, eyayiyeyona nto yatshintshayo.
Ivalve yokukhupha igesi isefana nanamhlanje kwaye iquka irabha diaphragm ngaphakathi kwesitofu esibunjiweyo.Uxinzelelo lomphezulu ngokuchasene nomzimba wevalve lugcinwa ngumaleko olwelo kumaleko angaphakathi wevalvu.
Ulwelo lutyibilika luze luhambise i-diaphragm xa umahluko woxinzelelo ufikelela kuxinzelelo lomphezulu.Oku kwenza kube lula ukuba irhasi ibaleke ngelixa igcina ioksijini ngaphandle kwepakethe.
I-drawback yeevalvu zokukhupha amanzi
Kukho izizathu ezininzi zokuba abantu abarokhayo banokugqiba ekubeni bangasebenzisi iivalvu zokukhupha umoya, nangona beyitshintshile indlela epakishwa ngayo ikofu.
Impembelelo ecacileyo kukuba iphakamisa ixabiso lokupakisha.Ezinye iirosaji zikwanexhala lokuba iivalvu zikhawulezisa ilahleko yearomatics.Bafumanise ukuba ukuvala ibhegi ngaphandle kwesivalo kunokubangela ukuba ikhukhumale kwaye yande kodwa ayibangeli ukuba iqhume.
Ngenxa yoku, aba baroki bahlala bethatha isigqibo sokucofa-tywina ikofu yabo endaweni yoko.
Ukungaqiniseki malunga nokuba iivalvu zokukhupha umoya ziyaphinda zisetyenziswe ngomnye umba kubo.
Kuhlala kukho ulwazi oluncinci olufumanekayo malunga nokwahlulwa okufanelekileyo kunye nokuhlaziywa kwakhona kweevalvu zokukhupha umoya.Ngenxa yokuprintwa okungaqhelekanga kwemiyalelo yokuphinda isetyenziswe kwi-valve kwi-coffee package, inxalenye enkulu yokungaqondi kakuhle idluliselwa kumthengi.
Abathengi baya beyiqonda ngakumbi indlela ukuthenga kwabo okuchaphazela ngayo okusingqongileyo.Ngenxa yoko, banokukhetha uhlobo olwahlukileyo lwekofu ukuba iphakheji ayinalo ulwazi lokurisayikilishwa.
Iiroatha zisenokukhetha iivalvu zokususa igasi eziphinda zisetyenziswe kwiingxowa zabo zekofu njengesisombululo.Ezi zinokudityaniswa ngokukhawuleza nangempumelelo kwipakethe, kwaye ezinye zazo zinokusebenzisa ukuya kuthi ga kwi-90% yeplastiki encinci.
Njengenye indlela, iivalvu ezithile zokukhupha igesi zenziwe kwi-bioplastics efana ne-polylactic acid, efikelelekayo kakhulu kwi-roasters kunye nokusingqongileyo.
Unxibelelwano lwemiyalelo yokulahlwa kwevalve, efana nokuba ingasuswa njani ukuze isetyenziswe ngokutsha, kwipakethe yekofu ibalulekile xa usebenzisa olu khetho.
Ngaba kuyimfuneko ukubandakanya iivalve zokukhupha amanzi kuzo zonke iipakethe zekofu?
Izinto ezininzi zinokuphembelela ukhetho lomtshisi wokusebenzisa ivalve yokukhupha umoya.Ezi ziquka iimpawu zokuqhola nokuba ikofu ithengiswa iimbotyi ezipheleleyo okanye umhlaba.
Iirosti ezimnyama, umzekelo, zikholisa ukukhupha i-degas ngokukhawuleza kunezorosti ezikhaphukhaphu, ngelixa zinokuqokelelana kwerhasi enkulu.Oku kubangelwa yinto yokuba indlela ezimile ngayo iimbotyi ziba neentunjana njengoko zichitha ixesha elininzi kwi-roaster.
Abo baqhotsayo kufuneka baqale bafunde indlela abathengi babo abasebenzisa ngayo ukutya.Oku kuya kunceda ekumiseleni ubungakanani obuyi-avareji bekofu epakishiweyo kunye nemithamo yeodolo eyimfuneko.
Xa ikofu ithengiswa ngamanani amancinci, ngokuqhelekileyo ayinalo ixesha elaneleyo lokubeka ubunzima ngokupakisha ngokungabikho kwevalve ye-degassing.Abathengi baya kusela ikofu ngokukhawuleza kunokuba bebenokwenza ngezixa ezikhulu, ezinje ngeengxowa ezi-1kg.
Kwiimeko ezinjalo, abaroki basenokukhetha ukuthengisa izixa ezisezantsi zekofu abathengi.
Kukho iindlela zokuthintela i-oxidation yee-roasters ezingasebenzisi izivalo zokukhupha igesi.Ukugungxulwa kwe-nitrogen, umzekelo, kusetyenziswa ziiroatha ezithile, ngelixa ezinye ziquka i-oksijini kunye neengxowa ezifunxayo ze-CO2 kwiipakethe zazo.
Ii-roasters zinokuqinisekisa ukuba indlela yokuvala yokupakisha ayinamoya kangangoko kunokwenzeka.Ukuvalwa kwe-zip, umzekelo, kunokuphumelela ngakumbi kunethayi ye-tin ekugcineni i-oxygen ingangeni kwiingxowa zekofu.
Esinye sezixhobo ezahlukeneyo ezifumanekayo kwii-roasters ukuqinisekisa ukuba ikofu yabo ihanjiswa kubathengi bekwimeko egqibeleleyo yi-valve yokukhupha amanzi.
Nokuba ngaba aba roatha bathatha isigqibo sokusebenzisa ivalve yokukhupha amanzi, ukusebenza nengcali yokupakisha kunokunceda ukugcina iimpawu zekofu kwaye ugcine abathengi bebuyela ngaphezulu.
Iivalvu zokukhupha amanzi ezikwazi ukurisayiklishwa ngokupheleleyo kunye ne-BPA-free ziyafumaneka kwi-Cyan Pak kwaye zinokuphinda zisetyenziswe kunye nayo yonke ipakethe yekofu.I-cap, i-elastic disc, i-viscous layer, ipleyiti ye-polyethylene, kunye nesihluzo sephepha zizinto eziqhelekileyo zezi valve.
Abancedi kuphela ukwenza imveliso enokusetyenziswa ngabathengi ngokulula, kodwa banciphisa nemiphumo eyingozi yokuba i-coffee packaging ihambelana nokusingqongileyo.
Ukukunika ezinye iindlela ezizezinye zokugcina ikofu yakho isentsha, sikwabandakanya iizipkhi, iiziphu zevelcro, amaqhina, kunye neenotshi zokukrazula.
Abathengi banokuqiniseka ukuba ipakethe yakho ayinaziphazamisi kwaye intsha ngokusemandleni ngokukrazula iinotshi kunye neziphu ze-velcro, ezibonelela ngesiqinisekiso sokuvalelwa kokuvalwa okuqinileyo.Izingxobo zethu ezisezantsi ezithe tyaba zinokusebenza kakuhle ngamaqhina eenkcenkce ukugcina ingqibelelo yesakhiwo sokupakishwa.
