Iyo imwe-nzira yegasi yekutsinhana vharafu, iyo yakagadzirwa muma1960s, yakachinja zvachose kurongedza kofi.
Isati yasikwa, zvaive zvakaoma kuchengeta kofi mune inochinjika, isina mhepo yekurongedza.Degassing mavharuvhu zvakazoita kuti awane zita regamba risingazivikanwe munzvimbo yekurongedza kofi.
Mavharuvhu ekubvisa gasi akaita kuti zvikwanisike kuti vanogocha vatakure zvinhu zvavo kure kupfuura kare vachibatsirawo vatengi kuchengetedza kofi yavo yakachena kwenguva refu.
Multiple specialty roasters akabatanidza magadzirirwo ebhegi rekofi kuti asanganise inochinjika kurongedza kofi ine yakasanganiswa degassing valve, uye zvave zvakajairika.
Tataura izvozvo, mavharuvhu ekubvisa gasi anoda kuiswa pamusoro pekofi yekurongedza kuti ishandiswe?
Ko mabhegi ekubvisa gasi mavharuvhu anoshanda sei?
Degassing valves inoshanda senzira imwe chete inoita kuti magasi abve kwaaigara.
Magasi anobva kuzvinhu zvakaputirwa anoda nzira yekutiza munzvimbo yakavharwa pasina kukuvadza kutendeka kwebhegi.
Mazwi okuti "out-gassing" uye "off-gassing" anowanzoshandiswa zvakasiyana-siyana nekuita degassing mubhizinesi rekofi.
Degassing ndiyo nzira iyo bhinzi yekofi yakagochwa inoburitsa kabhoni dhayokisaidhi iyo yakambotorwa.
Nekudaro, pane musiyano mukuru pakati pekubuda-gassing uye degassing mune inoshanda mazwi echemistry, kunyanya geochemistry.
Out-gassing ndiro izwi rinoshandiswa kutsanangura kudzingwa kwegasi kwega uye kwechisikigo kubva mudzimba dzawo dzakasimba kana dzemvura panguva yekuchinja kwenyika.
Nepo degassing ingangoratidza kumwe kubatanidzwa kwevanhu mukuparadzaniswa kwemagasi anoburitswa, izvi hazvisi nguva dzose.
Kunze-gassing mavharuvhu uye degassing mavharuvhu kazhinji ane dhizaini yakafanana, achiwedzera iyi terminological semantic musiyano kune kofi kurongedza.
Izvi zvinodaro kuti kuchinjana kwegasi kugone kuitika kana bhegi rekofi rakasvinwa kukurudzira kuchinjana kwegasi kana kuti zvinongoitika neambient yekunze nharaunda.
Chivharo, elastic disc, viscous layer, polyethylene plate, uye pepa sefa ndizvo zvakajairika zvikamu zve degassing valves.
Vhuru ine rabha diaphragm ine viscous layer ye sealant fluid mukati, kana kofi-yakatarisana, parutivi rwe diaphragm.Izvi zvinoita kuti tension yepasi irambe ichipikisana nevharuvhu.
Kofi inoburitsa CO2 sezvainobvisa, ichiwedzera kudzvanywa.Iyo mvura inosundira diaphragm kubva panzvimbo kana kudzvanywa mukati mehomwe yakakangwa yekofi kwakapfuura kushushikana kwepamusoro, zvichibvumira iyo yakawedzera CO2 kutiza.
Mavharuvhu ekubvisa gasi anodiwa here pakurongedza kofi?
Degassing mavharuvhu chinhu chakakosha chemabhegi ekofi ane dhizaini yakanaka.
Magasi anogona kuungana munzvimbo yakamanikidzwa kana asina kuverengerwa mupakeji akagadzirirwa kofi ichangobva kugochwa.
Uyezve, iyo yekuputira inogona kubvarura kana zvimwe kukanganisa kuvimbika kwebhegi rekofi zvichienderana nerudzi uye maitiro ezvigadzirwa.
Makabohaidhiretsi akaomeswa akatsemurwa kuita madiki, mamorekuru ari nyore panguva yekugochwa kwekofi yakasvibira, uye zvese mvura nekabhoni dhayokisaidhi zvinogadzirwa.
Muchokwadi, kukurumidza kuburitswa kwemamwe magasi aya nehunyoro ndiko kunokonzeresa "kutanga kutsemuka" kunoshandiswa nevazhinji vanogocha kudzora uye kugadzirisa maitiro avo ekugocha.
Zvisinei, mushure mekutsemuka kwekutanga, magasi anoramba achiumba uye haaparadzi zvachose kusvikira mazuva mashomanana mushure mekugocha.Iri gasi rinoda kwekuenda sezvo richiramba richiburitswa kubva kubhinzi yekofi yakakangwa.
Kofi ichangobva kugochwa haingagamuchirwi bhegi rekofi rakavharwa risina vharafu kuitira kutiza gasi.
Kana kofi yakuyiwa uye donhwe rekutanga remvura rawedzerwa mupoto yekubikisa, imwe carbon dioxide inogadzirwa panguva yekugochwa icharamba iripo mubhinzi uye ichadzingwa.
Kutumbuka uku, kunoonekwa mukudururwa-pamusoro, kazhinji chiratidzo chechokwadi chekuti kofi yakagochwa ichangobva kugochwa.
Zvakafanana nemabhegi ekofi, shoma shoma yekabhoni dioxide mumusoro inogona kubatsira mukuwedzera hupenyu hwesherufu nekuvhara okisijeni inokuvadza kubva kumhepo yakatenderedza.Zvisinei, kuwanda kwegasi kunowedzera kunogona kukonzera kuputsika kwepakeji.
Izvo zvakakosha kuti vanogocha vafunge kuti mavharuvhu anoshandiswa mukurongedza kofi achagara kwenguva yakareba sei.Sarudzo dzekupedzisira-kwe-hupenyu kurasa kana mushandisi apedza kushandisa chigadzirwa anogona kukanganiswa nekusiyana kwezvinhu.
Zvingave zvine musoro kuti mavharuvhu ave akafanana kana, semuenzaniso, mabhegi ekofi emugocha akagadzirwa kuti agadziriswe muindasitiri.
Imwe nzira ndeyekushandisa degassing valve inogona kushandiswa zvakare.Izvo zvakakosha kuti uzive kuti neiyi sarudzo, vashandisi vaizodikanwa kubvisa mavharuvhu kubva pakurongedza uye kurasira zvakasiyana.
Kana zvinhu zvekurongedza zvichigona kuraswa nehushoma hwekuedza kwevatengi uye, zvine hungwaru, sechikamu chimwe chete, ivo vanowanzove nekwaniso yakanakisa yekuve cradle-to-grave inogoneka.
Pane zvakawanda zvingasarudzwa zvezvakatipoteredza zvine hushamwari degassing mavharuvhu.Recyclable degassing mavharuvhu anopa zvakafanana zvivakwa semapurasitiki pasina kuipa kwezvakatipoteredza mhedzisiro sezvo anogadzirwa achishandisa jekiseni-akaumbwa bioplastics inotorwa kubva kune zvinogonekazve zviwanikwa, sezvirimwa.
Kuti ive nechokwadi chekuti kurongedza kunosvika panzvimbo chaiyo, vanogocha vanofanira kurangarira kuyeuchidza vatengi nzira yekurasa mabhegi ekofi akaraswa.
Ndekupi pakuvhara kwekofi kunofanira kuiswa mavharuvhu ekubvisa?
Angave mabhegi ekumira kana mabhegi akaiswa parutivi, kurongedza kunochinjika kwabuda sesarudzo inosarurwa nemusika yekurongedza kofi.
Degassing mavharuvhu ari pachena akakosha kuchengetedza pasuru kutendeseka kwezvichangobva kugochwa bhinzi dzekofi sezvavanoita kudaro.
Nzvimbo chaiyo yevhavha, zvisinei, inofanira kurangarirwa.
Vanogocha vanogona kusarudza kuisa mavharuvhu zvisingatarisike kana munzvimbo inoenderana nechitarisiko chechiratidzo chavo, zvinoenderana nezvavanoda.
Kunyangwe kuiswa kwevharuvhu kunogona kuchinjwa, mavara ese akagadzirwa akaenzana?
Iyo degassing valve inofanirwa kunge iri mumusoro webhegi kuti iite zvakanakisa sezvo pano ndipo panounganidzwa ruzhinji rwemagasi akaburitswa.
Iko kunzwika kwemaitiro emabhegi ekofi kunofanirwawo kuverengerwa.Nzvimbo yepakati ndiyo yakanaka sezvo kuisa vharafu padhuze nepadhuze kunogona kunetesa kurongedza.
Nekudaro, kune kumwe kuchinjika maererano nenzvimbo iyo vanogocha vanogona kuisa vharafu yekubvisa, kunyanya pamwe nepakati mutsara, padhuze nepamusoro pekurongedza.
Kunyange zvazvo zvikamu zvekurongedza zvinoshanda zvinonzwisiswa kuti zvine chinangwa chaicho nevatengi vemazuva ano vane hanya nezvezvakatipoteredza, dhizaini yebhegi ichiri kuita basa rakakura mukutenga sarudzo.
Kunyangwe zvingave zvakaoma, mavharuvhu ekudzikisa haafanire kufuratirwa kana uchigadzira mifananidzo yemabhegi ekofi.
PaCyan Pak, tinopa vanogocha sarudzo pakati pekare-imwe nzira yekubvisa gasi mavharuvhu uye 100% anogona kushandiswazve, BPA-isina mavharuvhu ekubvisa gasi emabhegi avo ekofi.
Mavharuvhu edu anochinjika, akareruka, uye ane mutengo wakafanira, uye anogona kushandiswa nechero sarudzo yedu yekurongedza kofi ine hushamwari.
Vanogocha vanogona kusarudza kubva kwakasiyana-siyana kudzokororwa zvinhu zvinoderedza marara uye kutsigira hupfumi hwakatenderera, kusanganisira kraft bepa, bepa remupunga, uye multilayer LDPE kurongedza ine eco-inoshamwaridzika PLA yemukati.
Pamusoro pezvo, nekuti isu tinoshandisa yekucheka-kumucheto dhijitari yekudhinda tekinoroji, yedu yese mutsara wekofi yekurongedza inogoneka zvachose.Izvi zvinotigonesa kukupa iwe nekukurumidza kutendeuka nguva ye40 maawa uye 24-awa yekutumira nguva.
