Kuchengetedzwa kwekutsva kwekofi yavo yakakangwa inyaya yakakosha kune vanogocha kofi.The degassing valve chinhu chakakosha pakuita izvi.
Iyo degassing valve, iyo yaive patented muna 1960, inzira imwe chete inobvumira bhinzi dzekofi kuburitsa zvinyoro nyoro magasi akadai secarbon dioxide (CO2) pasina kusangana neokisijeni.
Mavharuvhu ekubvisa gasi, anoita seakareruka epurasitiki nozzles, zvinhu zvinokosheswa zvikuru zvinobvumira kofi yakagochwa kufamba madaro marefu pasina kukuvadzwa.
Nekudaro, kusanganisirwa kwavo mukuchengetedza kofi kurongedza kunogona kunetsa nekuti kazhinji kunofanirwa kubviswa kusati kwaraswa.Nekuda kweizvozvo, vamwe vanogocha vanogona kushandisa mabhegi asina mavharuvhu ekubvisa kana kofi yavo ichizopihwa nekukurumidza mushure mekugocha.
Ramba uchiverenga kuti udzidze zvakawanda nezve degassing valves uye dzimwe nzira dzinowanikwa kune vanogocha.
Chii chinangwa chevhavha yekubvisa gasi?
Kofi inoratidza shanduko huru dzemuviri kana yakagochwa, nehuwandu hwayo hunowedzera kusvika 80%.
Uyezve, kugocha kunoburitsa magasi akabatwa mubhinzi, angangoita 78% ayo ari carbon dioxide (CO2).
Degassing inoitika panguva yekurongedza, kukuya, uye kunwa kwekofi.Kune akaomarara, epakati, uye akakwenenzverwa saizi, semuenzaniso, 26% uye 59% yeCO2 mukofi inoburitswa mushure mekukuya, zvichiteerana.
Nepo kuvepo kwe CO2 kuchiwanzo chiratidzo chekutsva, kunogona kuve nekukanganisa kunhuhwirira uye hwema hwekofi.Semuenzaniso, kofi isina kupihwa nguva yakakwana ye degas inogona kuburitsa mabhubhu panguva yekubika, zvichikonzera kudhirowa kusingaenderane.
Degassing inofanirwa kutariswa nekuchenjera sezvo yakawandisa inogona kukonzera kuti kofi ive yakarebesa.Nekudaro, kusakwana degassing kunogona kukanganisa mabudiro ekofi uye kugadzira crema.
Roasters vakawana nzira dzinoverengeka dzekudzora degassing maitiro nekufamba kwenguva kuburikidza nekuyedza uye kukanganisa.
Kushandiswa kwepakeji yakaoma iyo inogona kumira kumanikidzwa kwe CO2 kuunganidza kana kubvumira kofi kuti degas isati yarongedza zvose zvakashandiswa semhinduro munguva yakapfuura.Vakaiedzawo kofi inovhara vacuum-sealing ichiri mugaba rayo.
Zvisinei, nzira imwe neimwe yakanga ine zvayakaipira.Semuenzaniso, zvakatora nguva yakareba kuti kofi iite degas, iyo yakafumura bhinzi kune oxidation.Kurongedza kwakaoma, kune rumwe rutivi, kwaidhura uye kwakaoma kufamba.
Kunyanya kunhuhwirira kunhuhwirira kwekofi kwakabviswa panguva yekuvhara vacuum, izvo zvaive nemhedzisiro yakaipa pahunhu hwayo hwekunzwa.
Iyo degassing valve yakagadzirwa mu1960s neItaly yekurongedza kambani Goglio, iyo yaive nguva yekuchinja.
Iyo degassing valve ichiri yakangofanana nhasi uye inoumbwa nerabha diaphragm mukati mejekiseni rakaumbwa vharafu.Kudzvinyirirwa kwepamusoro kunopesana nemuviri wevharuvhu kunochengetedzwa nechikamu chemvura muchikamu chemukati chevharuvhu.
Mvura inotsvedza ichienda uye inofambisa diaphragm apo mutsauko wekumanikidzika unosvika pakurwisana kwepamusoro.Izvi zvinoita kuti gasi rikwanise kupukunyuka uku uchichengeta oxygen kunze kwepasuru.
Degassing mavharuvhu 'drawback
Pane zvikonzero zvakati kuti nei vanogocha vanogona kusarudza kusashandisa mavharuvhu ekubvisa, zvisinei nekuti ivo vakashandura nzira iyo kofi inorongedzerwa.
Mhedzisiro yakanyatsojeka ndeyekuti inosimudza mutengo wekurongedza.Vamwe vanogocha vari kunetsekawo kuti mavharuvhu anokurumidzira kurasikirwa nearomatics.Vakaona kuti kuvhara bhegi risina vharuvhu kunogona kuita kuti rizvitutumadze uye rikure asi hazviiti kuti riputika.
Nekuda kweizvi, ava vanogocha vanowanzo funga kuvhara-kusimbisa kofi yavo panzvimbo.
Kusavimbika pamusoro pekuti degassing mavharuvhu anogona kushandiswazve imwe nyaya navo.
Pane kazhinji kacho ruzivo rudiki runowanikwa pakupatsanurwa kwakakodzera uye kudzokororwa kwemavharuvhu ekubvisa.Nekuda kwekusadhindwa kudhindwa kwemirairo yekudzokorodza vharafu pakubika kwekofi, chikamu chikuru chekusanzwisisa uku chinoendeswa kune mutengi.
Vatengi vari kuwedzera kuziva kuti kutenga kwavo kunokanganisa sei nharaunda.Nekuda kweizvozvo, vanogona kusarudza imwe mhando yekofi kana pasuru yacho isina ruzivo rwekudzokorodza.
Vanogocha vangasarudze mavharuvhu ekubvisazve gasi kumabhegi avo ekofi semhinduro.Izvi zvinogona kukurumidza uye zvinobudirira kubatanidzwa mukurongedza, uye mamwe acho anogona kushandisa anosvika makumi mapfumbamwe muzana epurasitiki mashoma.
Seimwe nzira, mamwe mavharuvhu ekubvisa anogadzirwa kubva kubioplastics akadai polylactic asidhi, iyo inodhura zvakanyanya kune vanogocha uye inoshamwaridzana nenharaunda.
Kukurukurirana kwemirairo yekurasa yevharuvhu, senge mabvisirwe ayo kuti idzokororwe, pamikombe yekofi yakakosha pakushandisa sarudzo idzi.
Izvo zvinodikanwa here kusanganisa mavharuvhu e degassing pane yega kofi kurongedza?
Zvinhu zvakawanda zvinogona kupesvedzera sarudzo yemugocha kushandisa vharafu yekubvisa gasi.Izvi zvinosanganisira hunhu hwekugocha uye kana kofi inotengeswa bhinzi yese kana pasi.
Kugocha kwakasviba, semuenzaniso, kunowanzoita degas nekukurumidza kupfuura kugocha kwakareruka, nepo kuine gasi rakakura.Izvi zvinokonzerwa nekuti maumbirwo ebhinzi anowedzera kuva neburi sezvo achipedza nguva yakawanda achigocha.
Vanogocha vanofanira kutanga vadzidza madyiro evatengi vavo.Izvi zvichabatsira mukuona avhareji saizi yekofi yakapetwa pamwe nemavhoriyamu eodha anodiwa.
Kana kofi inotengeswa muhuwandu hushoma, kazhinji haina nguva yakakwana yekuunza matambudziko nekurongedza mukushaikwa kwevhavha ye degassing.Vatengi vanozonwa kofi nekukurumidza kupfuura zvavangaite neakawanda, senge mabhegi e1kg.
Mumamiriro ezvinhu akadaro, vanogocha vanogona kusarudza kutengesa vatengi zvishoma zvekofi.
Pane nzira dzekudzivirira oxidation kune vanogocha vasingashandisi mavharuvhu ekubvisa.Nitrogen flushing, semuenzaniso, inoshandiswa nevamwe vanogocha, nepo vamwe vachisanganisira okisijeni uye CO2 inonyudza masaga mupakeji yavo.
Vanogocha vanogona zvakare kuve nechokwadi chekuti dhizaini yekuvhara yekurongedza haina mhepo inopinza sezvinobvira.Kuvharwa zipi, semuenzaniso, kunogona kubudirira kupfuura tai yekuchengeta oxygen kuti isapinda mumabhegi ekofi.
Chimwe chezviridzwa zvakasiyana-siyana zviripo kune vanogocha kuti vaone kuti kofi yavo inounzwa kune vatengi vari mumamiriro ezvinhu akakwana ndeye degassing valves.
Vangave vanogocha vakasarudza kushandisa vharafu yekubvisa gasi, kushanda nenyanzvi yekurongedza kunogona kubatsira kuchengetedza hunhu hwekofi uye kuchengetedza vatengi kudzoka kune zvimwe.
Degassing mavharuvhu anonyatso kudzokororwa uye BPA-isina anowanikwa kubva kuCyan Pak uye anogona kudzokororwa pamwe nekumwe kurongedza kwekofi.Chivharo, elastic disc, viscous layer, polyethylene plate, uye pepa sefa ndizvo zvinozivikanwa zvikamu zvemavharuvhu aya.
Ivo havangobatsiri kugadzira chigadzirwa icho vatengi vanogona kushandisa nyore, asi ivo zvakare vanoderedza zvinokuvadza izvo zvinokonzeresa kofi packaging pane zvakatipoteredza.
Kuti tikupe dzimwe dzimwe nzira dzekuchengeta kofi yako iri nyowani, isu tinosanganisirawo maziplock, velcro zipi, matai, uye rip notches.
Vatengi vanogona kuve nechokwadi chekuti pasuru yako haina tamper-yemahara uye nyowani sezvinobvira nekubvarura notches uye velcro zippers, izvo zvinopa vimbiso yekunzwa yekuvhara kwakasimba.Homwe dzedu dzepazasi dzakati sandara dzinogona kushanda zvakanyanya nemarata kuitira kuchengetedza chimiro chekurongedza.
