Unoziva here? Nyemba dzekofi dzinotanga kuora nekuora kana dzangobikwa! Mukati memaawa angangoita gumi nemaviri ekugocha, kuora kunoita kuti nyemba dzekofi dzichembere uye kunaka kwadzo kunoderera. Saka, zvakakosha kuchengeta nyemba dzakaibva, uye kurongedza kwakazara nenitrogen uye kwakamanikidzwa ndiyo nzira inoshanda kwazvo yekurongedza.
Heano mamwe maitiro ekuchengetedza bhinzi dzakaibva, uye ndakapawo zvakanakira nezvadzinoipira:
Kurongedza kusina kuvharwa
Nyemba dzekofi dzinochengetwa mumapakeji asina kuvharwa kana mune zvimwe zvirongo zvakazara nemhepo (senge madhiramu akafukidzwa), uye nyemba dzakaibva dzichakurumidza kukura. Zvakanaka, zvakanaka kuravira nyemba dzakaibva dzakaputirwa nenzira iyi mukati memazuva 2-3 mushure mekubikwa.
Bhegi revharuvhu remhepo
Bhegi revharuvhu rinotenderera rimwe chete ndiro rinopakwa zvakanyanya muindasitiri yekofi yepamusoro. Rudzi urwu rwekurongedza runobvumira gasi kubuda kunze kwebhegi uku richidzivirira mhepo yakachena kupinda. Bhinzi dzakakura dzakachengetwa mumhando iyi yekurongedza dzinogona kuramba dziri nyowani kwemavhiki akati wandei. Mushure memavhiki mashoma, shanduko inonyanya kuoneka muvharuvhu rekurongedza bhinzi kurasikirwa necarbon dioxide nekunhuhwirira. Kurasikirwa necarbon dioxide kunonyanya kuoneka panguva yekuburitsa kofi yakawanda, Nekuti rudzi urwu rwekofi rucharasikirwa nekrimu yakawanda.
Bhegi revharuvhu remhepo rakavharwa neVacuum
Kuvhara vacuum kunoderedza zvakanyanya kuoxidation yebhinzi dzakabikwa mubhegi remhepo, zvichinonotsa kurasikirwa nekunaka.
Bhegi revharuvhu rekuzadza nitrojeni
Kuzadza bhegi revharuvhu remhepo nenitrogen kunogona kuderedza mukana wekuoxidation kusvika pazero. Kunyangwe bhegi revharuvhu remhepo richigona kuderedza oxidation yebhinzi dzakabikwa, kurasikirwa negasi nekumanikidzwa kwemhepo mukati mebhinzi kunogona kukuvadza zvishoma. Kuvhura bhegi revharuvhu remhepo rakazara nenitrogen rine bhinzi dzakabikwa mushure memazuva kana mavhiki akati wandei ekubika kuchaita kuti kuchembera kukurumidze kupfuura bhinzi dzakabikwa itsva, sezvo bhinzi dzakabikwa panguva ino dzine kumanikidzwa kushoma kwemhepo yemukati kudzivirira okisijeni kupinda. Semuenzaniso, Kofi inochengetwa mubhegi revharuvhu kwevhiki ichiri kutsva, asi kana chisimbiso chikasiyiwa chakavhurika kwezuva rese, kuchembera kwayo kuchaenzana nebhinzi dzakachengetwa mumapakeji asina kuvharwa kwevhiki rapfuura.
Bhegi rekudzvanya reVacuum
Mazuva ano, vanhu vashoma chete vanogocha bhinzi vachiri kushandisa mabhegi ekumanikidza vacuum. Kunyangwe mhando iyi yekurongedza ichigona kuderedza oxidation, gasi rinobuda kubva mubhinzi rinogona kukonzera kuti mabhegi ekurongedza awedzere, zvichiita kuti kuchengetwa nekutarisira zvisashande.
Kurongedza kwakazara nenitrogen uye kwakamanikidzwa
Iyi ndiyo nzira inoshanda zvikuru yekurongedza. Kuzadza nenitrogen kunogona kudzivirira oxidation; Kuisa simba pakuisa (kazhinji kacho mubhodhoro) kunogona kudzivirira gasi kuti risabude kubva mubhinzi. Pamusoro pezvo, kuisa bhinzi dzekofi mukuisa iyi munzvimbo inodziya zvishoma (kana dzichitonhora zviri nani) kunogonawo kunonotsa kukwegura kwebhinzi dzakaibva, zvichiita kuti dzirambe dziri itsva mushure memwedzi yakati wandei yekubikwa.
paketi yakaomeswa nechando
Kunyange hazvo vamwe vanhu vachiri kusava nechokwadi nezvenzira iyi yekurongedza, kurongedza kwakaomeswa nechando kunoshanda zvikuru pakuchengetwa kwenguva refu. Kurongedza kwakaomeswa nechando kunogona kuderedza mwero weoxidation neinopfuura 90% uye kunononoka kushanduka kwemhepo.
Kutaura zvazviri, haufanirwe kunetseka nezvekunyorova kwemukati kwebhinzi dzakakangwa dzichinyatsooma, nekuti hunyoro uhwu huchabatanidzwa nefiber matrix iri mukati mebhinzi, saka haigone kusvika pachando. Nzira yakanakisa yekuisa bhinzi dzekofi muchando ndeyekuisa chikamu chimwe (poto imwe kana kapu imwe) yebhinzi mubhegi rekumanikidza vacuum, wozodziisa muchando. Kana uchida kudzishandisa gare gare, usati wavhura paki uye wowedzera kukuya bhinzi, bvisa paki yacho mufiriji woisiya patembiricha yemukamuri.
Ok Packaging yave ichinyanya kugadzira mabhegi ekofi akagadzirwa nevanhu kwemakore makumi maviri. Kana muchida kudzidza zvakawanda, ndapota shanyirai webhusaiti yedu:
