Zisebenza njani iivalvu zokukhupha umoya?

Yonke i-roaster ifuna abathengi babo bafumane okuninzi kwikofu yabo.

Ukuze uvelise ezona mpawu zibalaseleyo zekofu eluhlaza ekumgangatho ophezulu, abaroyi bachitha umzamo omkhulu bekhetha iprofayile eyosiweyo.

Ngaphandle kwawo wonke lo msebenzi kunye nolawulo olungqongqo lwekhwalithi, ukuba ikofu ipakishwe ngokungafanelekanga, amava omthengi amabi anokwenzeka.Ikofu eyosiweyo iya konakala ngokukhawuleza ukuba ayipakishwanga ukugcina ubutsha kunye nomgangatho wayo.

Umthengi usenokuphulukana nethuba lokungcamla kwa ezo ncasa zifana nezo zazisenziwa yirosti xa kusenziwa iikomityi.

Ukufaka iivalvu zokukhupha amanzi kwiingxowa zekofu yenye yezona ndlela zilungileyo zoomatshini bokutshisa ukunqanda ukonakaliswa kwekofu eyosiweyo.

Enye yezona ndlela zidumileyo nezisebenzayo zokugcina iimpawu zokuziva kunye nokuthembeka kwekofu kukusebenzisa iivalve zokukhupha amanzi.

Qhubeka ufunda ukuze ufumanise ukuba zisebenza njani iivalvu zokukhupha amanzi kunye nokuba ungaziphinda uzisebenzise ngeengxowa zekofu.

Kutheni iibhegi zekofu ezineevalve zokukhupha amanzi zivela kwiiroatha?

Ikharbhon dayoksayidi (CO2) iqokelelana kakhulu ngaphakathi kweembotyi zekofu ngexesha lokugcadwa.

Ngenxa yale mpendulo, imbotyi yekofu ikhulisa malunga ne-40% ukuya kwi-60%, enempembelelo ebonakalayo ebonakalayo.

Njengoko ixesha lekofu, i-CO2 efanayo eyayiqokelelwe ngexesha lokutshisa ikhutshwa ngokuthe ngcembe.Ukugcinwa okungonelanga kwekofu eyosiweyo kubangela ukuba i-CO2 ithathelwe indawo yi-oxygen, ethoba incasa.

Inkqubo yokudubula kweentyantyambo ngumfanekiso obangela umdla womthamo werhasi egcinwe kwiimbotyi zekofu.

Ukugalela amanzi phezu kwekofu ephantsi ngexesha lenkqubo yokuqhakaza kubangela ukukhululwa kwe-CO2, ekhawuleza inkqubo yokukhutshwa.

Kufuneka kubekho amaqamza amaninzi abonakalayo xa kusenziwa ikofu esandula kugcadwa.Ngenxa yokuba i-CO2 mhlawumbi ithathelwe indawo yioksijini, iimbotyi ezindala zinokuvelisa "iintyatyambo" ezincinci.

Ukuze kuqwalaselwe lo mba, ivalve yendlela enye yokukhupha umoya yayiyilungelo elilodwa lomenzi ngo-1960.

Iivalve ze-Degassing zenza ukuba i-CO2 iphume kwiphakheji ngaphandle kokuvumela i-oksijini ukuba ingene xa ifakwe kwiingxowa zekhofi.

Ukwenza izinto zibe zibi nakakhulu, kwezinye iimeko, ikofu inokuthi i-degas ngokukhawuleza, ifake isikhwama sekhofi.Iivalve ze-degassing zivumela irhasi evalelekileyo ukuba ibaleke, ikhusela ibhegi ukuba ingaphumi.

Iivalve zokukhupha amanzi kufuneka zifakwe kwipakethe yekofu ngelixa kuthathelwa ingqalelo inani lezinto.

Ngokomzekelo, i-roasters kufuneka ithathele ingqalelo inqanaba lokugcoba ngenxa yokuba i-roast emnyama idla ngokukhawuleza i-degas kunokuba i-roast elula.

Ngenxa yokuba imbotyi iye yehla ngakumbi, i-roast emnyama iyayikhawulezisa inkqubo yokukhupha umoya.Iifissures ezininzi ezincinci zikhona, ezivumela ukuba i-CO2 ikhululwe, kwaye iiswekile zinexesha elininzi lokutshintsha.

Iirosti ezikhanyayo zishiya ngaphezulu kwembotyi yomelele, nto leyo enokuthetha ukuba kuthatha ixesha elide ukuba idegas.

Ubungakanani yenye into onokucinga ngayo.I-roaster iya kuba nexhala elincinci malunga nebhegi yekofu ephumayo ukuba ipakisha imiqulu emincinci, iisampulu ezinjalo zokungcamla.

Umthamo weembotyi engxoweni uhambelana ngqo nomthamo we-CO2 okhutshwe.Kucetyiswa ukuba i-roasters epakisha iingxowa zekhofi ezinobunzima obungaphezu kwe-1 kg yokuthunyelwa kweenqanawa zithatha imiphumo ye-degassing kwi-akhawunti.

Iivalvu zokukhupha umoya: Zisebenza njani?

Ngeminyaka yoo-1960 kwaveliswa iivalve zokukhupha umoya nguGoglio woshishino waseItali.

Baye bajongana nomba obalulekileyo amashishini amaninzi ekofu ayenayo ngokukhupha igesi, i-oxidation, kunye nokugcina ubutsha.

Uyilo lwevalvu ye-Degassing luye lwatshintsha ngokuhamba kwexesha njengoko luye lwahlala luhlala luhlala kwaye lunendleko.

Iivalvu zanamhlanje zokukhupha umoya azilungelelani kuphela ngaphakathi kweengxowa zekofu, kodwa zifuna i-90% yeplastiki encinci.

Isihluzi sephepha, i-cap, i-elastic disc, i-viscous layer, ipleyiti ye-polyethylene, kunye ne-valve ye-degassing zizinto ezisisiseko.

Umaleko we-viscous wolwelo olutywiniweyo ugubungela ngaphakathi, okanye indawo ejonge ikofu, ye-diaphragm yerabha evalelwe kwivalvu, egcina ukuxinezeleka komphezulu ngokuchasene nevalve.

Njengoko ikofu ikhupha i-CO2, uxinzelelo luyanda.Ulwelo luya kuhambisa i-diaphragm xa uxinzelelo luwela ukunyanzeliswa komhlaba, ukuvumela ukuba i-CO2 eyongezelelweyo ibaleke.

Ivalve ivula kuphela xa uxinzelelo ngaphakathi kwebhegi yekofu inkulu kunoxinzelelo olungaphandle, ukuyibeka ngokulula.

Ukusebenza kweevalvu zokukhupha umoya

Ii-roasters kufuneka zicinge malunga nendlela i-valve ye-degassing, ehlala ifakwe kwiingxowa zekhofi, iya kuchithwa ngokupakishwa okuchithiweyo.

Ngokucacileyo, i-bioplastics ifumene ukuthandwa njengenye indlela kwiiplastiki ezenziwe ngepetroleum.

Ii-Bioplastics zineempawu ezifanayo nezeplastiki eziqhelekileyo kodwa zinempembelelo ephantsi kakhulu kokusingqongileyo njengoko ziveliswa ngokubilisa iikhabhohayidrethi ezivela kwimithombo ehlaziyekayo equka umoba, isitatshi sombona, nombona.

Iivalvu zokukhupha amanzi ezakhiwe ngezi zixhobo zilungele ukuphilisana kwendalo ngoku kulula ukuzifumana kwaye zinexabiso elincomekayo.

Iivalve zokukhupha amanzi ezenziwe ngezinto ezinokuphinda zisetyenziswe zinokunceda abatshisi bagcine amafutha efosili, banciphise impembelelo yekhabhoni, kwaye babonise inkxaso yabo yokuzinza.

Ukongeza, benza ukuba abathengi bakwazi ukulahla ngokufanelekileyo nangokucacileyo ukupakishwa kwekofu.

Abathengi banokuthenga isikhwama sekofu esizinzileyo xa iivalve ezizinzileyo zokukhupha amanzi zidityaniswa nezinto zokupakisha ezinokuphinda zisetyenziswe okanye ezixutywayo, njengephepha le-kraft eline-polylactic acid (PLA) laminate.

Oku kunokonyusa intembeko yophawu phakathi kwabathengi bangoku abanokuthi ngenye indlela batshintshe intembeko yabo kubakhuphisana abanobungani bendalo ukongezelela ekubeninika ukhetho olunomtsalane.

Kwi-CYANPAK, sibonelela ngee-roasters zekofu ukhetho lokongeza i-recyclable ngokupheleleyo, i-BPA-free degassing valves kwiingxowa zabo zekhofi.

Iivalvu zethu ziyaguquguquka, zikhaphukhaphu, kwaye zinexabiso elifanelekileyo, kwaye zinokusetyenziswa kunye naluphi na ukhetho lwethu lokupakisha ikofu oluhambelana nokusingqongileyo.

Ii-roasters zinokukhetha kwizinto ezahlukeneyo ezinokuphinda zisetyenziswe ezinciphisa inkunkuma kwaye zixhase uqoqosho olujikelezayo, kubandakanywa nephepha le-kraft, iphepha lerayisi, kunye ne-multilayer LDPE ukupakishwa kunye ne-eco-friendly PLA yangaphakathi.

Ngaphaya koko, sinikezela ngenkululeko yethu epheleleyo yokuyila abo baqhotsayo ngokubavumela ukuba bazenzele ezabo iibhegi zekofu.

Ungafumana uncedo kubasebenzi bethu boyilo ekuze nepakethe efanelekileyo yekofu.

Ukongezelela, sinika iingxowa zekofu eziprintiweyo kunye nexesha elifutshane lokuguqula iiyure ze-40 kunye neeyure ze-24 zokuthumela ixesha usebenzisa iteknoloji yokushicilela idijithali.

Ukongeza, i-CYANPAK ibonelela ngemilinganiselo ephantsi ye-odolo (MOQs) kwii-micro-roasters ezifuna ukugcina ukuguquguquka ngelixa bebonisa uphawu lwabo kunye nokuzinikela kokusingqongileyo.
