1. Nezvebhodhoro risina mweya

Zviri mukati mebhodhoro risina mweya zvinogona kuvharwa zvachose kubva kumhepo kudzivirira chigadzirwa kubva kune oxidizing uye kuchinja nekuda kwekubata mhepo, uye kubereka mabhakitiriya.Iyo yepamusoro-tech pfungwa inosimudzira chiyero chechigadzirwa.Vacuum mabhodhoro anopfuura nepamall anoumbwa necylindrical ellipsoidal mudziyo uye piston pazasi peseti.Nheyo yayo yekuronga ndeye kushandisa kupfupisa simba rekunetsekana chitubu, uye kusatendera mweya kupinda mubhodhoro, zvichikonzera vacuum mamiriro, uye kushandisa mhepo yekumanikidza kusundira piston pazasi pebhodhoro mberi.Zvisinei, nokuti simba rechitubu uye mhepo yemhepo haigoni kupa simba rakakwana, piston haigoni kusungirirwa zvakasimba kumadziro ebhodhoro, kana zvisina kudaro piston haizokwanisi kuenderera mberi nekuda kwekupikisa kwakanyanya;kana zvisina kudaro, kana piston iri kufambira mberi zviri nyore, ichave yakada kudonha Naizvozvo, bhodhoro revacuum rine zvakanyanya zvinodiwa pahunyanzvi hwemugadziri.

Kuunzwa kwemabhodhoro evacuum kunoenderana neazvino budiriro yezvigadzirwa zvekuchengetedza ganda, uye inogona kunyatso chengetedza hutsva hwemhando yezvigadzirwa.Nekudaro, nekuda kwechimiro chakaomesesa uye kudhura kwakanyanya kwemabhodhoro evacuum, kushandiswa kwevacuum bhodhoro kurongedza kunogumira kune yakaganhurwa nhamba yezvigadzirwa uye haigone kupedzwa zvizere mumall kuti isangane nezvinodiwa zvemazinga akasiyana eganda rekuchengetedza chigadzirwa kurongedza.

Mugadziri anoteerera kudzivirira uye kushongedzwa kwekutarisira ganda uye ganda rekuchengetedza chigadzirwa kurongedza, uye anotanga kukudziridza kushanda kweganda rekuchengetedza chigadzirwa kurongedza kuita pfungwa ye "mutsva", "yakasikwa" uye "inochengetedza-isina" yakanyatsokodzera.

2. Vacuum kurongedza unyanzvi

Vacuum kurongedza hunyanzvi ipfungwa nyowani ine mabhenefiti akakwana.Iyi hunyanzvi hwekurongedza yakabatsira akawanda mabhureki matsva uye mafomula matsva kufamba zvakanaka.Kana iyo vacuum packaging yaunganidzwa, kubva pakuzadza kwepakiti kusvika pakushandiswa kwemutengi, mweya mudiki unogona kupinda mumudziyo uye kusvibisa kana kusiyanisa zviri mukati.Iri isimba rekuputira vacuum-inopa yakachengeteka yekurongedza mudziyo wechigadzirwa kudzivirira kusangana nemhepo, mukana wekuchinja uye oxidation inogona kuitika panguva yekudzika, kunyanya izvo zvechisikigo zvinongedzo zviri kuda kuchengetedzwa nekukurumidza. .Nezwi rekufona, vacuum packaging inonyanya kukosha pakuwedzera hupenyu hwesherufu yezvigadzirwa.

Zvigadzirwa zvekurongedza zvevacuum zvakasiyana kubva kune zvakajairwa mashanga emhando yemapombi akajairwa kana pombi yekupfapfaidza.Vacuum packaging inoshandisa musimboti wekupatsanura mukati memukati kukanya nekuburitsa zviri mukati.Kana iyo diaphragm yemukati inofamba ichienda mukati mebhodhoro, kumanikidzwa kunoumbwa, uye zvinyorwa zviripo pane vacuum condition iri pedyo ne100%.Imwe nzira yevacuum ndeye kushandisa vacuum nyoro bhegi, yakaiswa mukati memudziyo wakaoma, pfungwa yezviviri inenge yakafanana.Iyo yekare inoshandiswa zvakanyanya uye inzvimbo yakakosha yekutengesa yemhando, nekuti inoshandisa zvishoma zviwanikwa uye inogona zvakare kutorwa se "girinhi".

Vacuum packaging inopawo chaiyo dosage control.Kana iyo gomba rekuburitsa uye chaiyo vacuum pressure yakaiswa, zvisinei nechimiro cheindenter, imwe neimwe dosi ndeyechokwadi uye yakawanda.Nokudaro, muyero unogona kugadziriswa nekushandura chikamu, kubva kune mashoma microliters kana mashoma milliliters, zvose zvinogadziriswa maererano nezvinodiwa zvechigadzirwa.

Kuchengetedzwa kwechigadzirwa uye hutsanana ndiwo akakosha kukosha kwevacuum kurongedza.Kana zviri mukati zvaburitswa kunze, hapana nzira yekuzvidzosera mune yekutanga vacuum packaging.Nekuti musimboti wekuronga ndeye kuona kuti chese chekushandisa chiri chitsva, chakachengeteka, uye chisina hanya.Sangano remukati rezvigadzirwa zvedu harina kupokana nezve ngura yechirimo, uye haizosvibisa zviri mukati.

Maonero emutengi anosimbisa kukosha kwevacuum zvigadzirwa zvisingaonekwe.Kuenzaniswa neyakajairwa pombi, maspray, mashanga, uye zvimwe zvinhu zvekurongedza, kushandiswa kwevacuum kurongedza kwakatsetseka, dosi yakagadziriswa, uye chitarisiko chakakwira, zvichiita kuti igare muchitoro chikuru chezvigadzirwa zveumbozha.
