Thekurongedza kwebhinzi yekofi yakabikwainonyanya kurebesa kunaka uye kunaka kwebhinzi dzekofi.Parizvino, nzira dzedu dzakajairika dzekuchengetedza bhinzi yekofi ndeidzi: uncompressed air packaging, vacuum packaging, inert gasi packaging, uye high-pressure packaging.
unpressurized air packaging
Kurongedza-isina kurongedza ndiko kurongedza kwakajairika kwatakamboona.Kuti ive chaiyo, inofanirwa kunzi air packaging.Bhegi rekurongedza rakazara nemhepo.Zvechokwadi, bhegi kana kuti mudziyo hauna mhepo.
Rudzi urwu rwekurongedza runogona kungoparadzanisa mhedzisiro yehunyoro, kurashikirwa uye chiedza pabhinzi yekofi, asi nekuda kwekusangana kwenguva refu nemhepo mubhegi kana mugaba, bhinzi dzekofi dziri mukati dzakashongedzwa oxidized, zvichikonzera nguva pfupi yekuravira. .mhedzisiro.
Iri rudzi rwekofi bhinzi yakaputirwa yakanakisa kuiswa mushure mekunge bhinzi yekofi yapera, kana zvikasadaro bhinzi yekofi inokonzera kuputika kana kuputika mushure mekunge bhinzi dzekofi dzapera muhombodo.Iye zvino, imwe-nzira yekupedza valve yakaiswa pahomwe kuti ive nechokwadi chekuti bhinzi yekofi haizoputika nebhegi rebhinzi nekuda kwekuneta.
vacuum packaging
Pane mamiriro maviri ekugadzirwa kwevacuum packaging: 1. Vhura mweya.2. Chinhu chinoshanduka uye chakapfava.
Zvechokwadi, teknolojia iyi inogonawo kushandiswa kune zvimwe zvinhu zvakaoma, asi zvinowanzojairika kushandisa zvimwe zvinyoro zvinyoro kuti zvive chigadzirwa chakaoma se "brick".
Iyi nzira yekuputira ichaita kuti kofi uye zvinhu zvekuputira zvinyatsoenderana, asi munharaunda iyi, bhinzi dzekofi dzinofanira kunge dzakapera zvachose, kana zvisina kudaro kusimba kwekuputira kwese kuchaderedzwa nekuda kwekuneta kwebhinzi dzekofi pachadzo.Inova yakapfava uye yakazvimba.Ndosaka zvakawanda zve “zvidhinha” zvaunoona muzvitoro zvikuru zviri kofi yakakuyiwa, kwete bhinzi.
Uye kurongedza kwakadaro kunowanzoshandiswa pamvura yakanyoroveswa bhinzi yekofi, iyo inogona kungounza hupenyu hupfupi hwesherufu uye kunhuhwirira kwakashata.Uye kana chigadziko chacho chakazara nezvinhu zvakaoma, mushure mokutsvaira, pane mutsauko wekumanikidzika pakati pebhinzi dzekofi pachadzo negaba.Kuburitswa kwegasi kubva kubhinzi dzekofi kunozadza nharaunda yese, nekudaro kuvharira kuvhurika kwekunhuhwirira.Kazhinji, kutsvaira kwezvinhu zvakaoma hakuna kunyatsoita sekunge kwezvinyoro zvinyoro.
Inert gasi kurongedza
Inert gasi kurongedza zvinoreva kuti inert gasi inotsiva mweya uri mubhegi, uye inert gasi inowedzerwa kuburikidza ne vacuum compensation tekinoroji.Mukushandiswa kwekutanga, mudziyo wakaburitswa mushure mekuzadza bhinzi yekofi, uyezve inert gasi yakaiswa mairi kuti ienzanise musiyano wekumanikidza mutangi.
Tekinoroji yemazuva ano ndeyekuzadza pasi pebhegi neine liquefied inert gasi uye kusvina mweya kunze kuburikidza nekubuda kwegasi inert.Kuita uku kunowanzoitwa pachishandiswa nitrogen kana kabhoni dhayokisaidhi - kunyangwe aya asingaonekwi semagasi akanaka.
Kofi bhinzi dzakarongedzerwa kuburikidza neinert gasi kazhinji dzine hupenyu hwesherufu hwekatatu nguva refu pane idzo dzakabviswa.Ehezve, chirevo ndechekuti ivo vanofanirwa kushandisa iyo imwechete yekurongedza zvinhu uye vane iyo yakafanana permeability yeokisijeni nemvura, uye kudzvanywa mupakiti kuchazara nekumanikidza mushure mekunge bhinzi dzekofi dzapera mushure mekuvharwa.
Nokugadzirisa mamiriro egasi inert zvinokwanisika kuchinja uye kudzora mararamiro evhavha yekofi uye kukanganisa kunaka kwavo.Zvechokwadi, zvakafanana nemhepo yepakiti, kuitira kudzivirira kumanikidzwa kwepakiti kubva pakakwirira, bhinzi yekofi inofanira kubudiswa isati yatakurwa, kana purogiramu ine imwe-phase vent valve inoshandiswa.
Kubva pakuona kwemutemo, kuwedzerwa kwegasi inert ibasa rekugadzirisa, kwete rekuwedzera, nokuti "inopukunyuka" nokukurumidza kana purogiramu yavhurwa.
Pressurized packaging
Kuputirwa kurongedza kwakangofanana nekuwedzera gasi inert, kunze kwekunge kusungirirwa kurongedza kunoisa kudzvanywa mukati memudziyo wekofi pamusoro pekumanikidza kwemhepo.Kana kofi ichizoiswa pasuru pakarepo mushure mekugochwa uye kutonhodzwa nemhepo, dzvinyiriro iri mukati memudziyo inowanzowedzera sezvo bhinzi dzinobuda.
Iyi tekinoroji yekurongedza yakafanana neyevacuum compensation tekinoroji, asi kuti utsungirire kudzvinyirirwa uku, zvimwe zvinhu zvakaoma zvinoshandiswa pakusarudza zvinhu, uye mavharuvhu ekuchengetedza anowedzerwawo kuve nechokwadi chekuchengetedza.
Kuputirwa nekumanikidzwa kunogona kunonoka "kuibva" kwekofi uye kugadzirisa kunaka.Chokwadi, kuchembera kwekofi kunogona kuita kuti kofi ive nekunhuhwirira kuri nani uye kuita kwemuviri, uye kuchembera kunogona kuvhara kunhuhwirira nemafuta ebhinzi dzekofi muchitokisi.
Kana yaburitswa, kuwedzera kwekumanikidza mumudziyo kunoderedza mutsauko wekumanikidza pakati pemukati webhinzi chimiro uye nharaunda yekurongedza.Nekuda kwekumanikidzwa kuchengetedza, kumanikidza kunokanganisawo bhinzi yekofi, iyo inogona kubvumira zvirinani kuti mafuta aite "nhoo" pamusoro pemadziro emadziro kuti aparadzanise mweya oxidation.
Nekuda kwekudzvanyirira musiyano pakati pemukati nekunze kwebhinzi dzekofi, chikamu checarbon dioxide chicharamba chichiburitswa kana bhegi rekofi ravhurwa.Sezvo maitiro eiyo oxidation yebhinzi yekofi ichanonoka mushure mekudzvanywa, iyo yakamanikidzwa kurongedza inofananidzwa nedzimwe nzira dzekurongedza.Zvinonzi zvicharebesa kunaka kwebhinzi dzekofi zvakanyanya.
