Gupakira Vacuum Niki

Gupakira Vacuum, bizwi kandi nka decompression packaging, nugukuramo umwuka wose mubikoresho bipakira hanyuma ukabifunga kugirango bigumane urugero rwo hejuru rwa decompression mumufuka. Ubuke bw'umwuka bungana n'ingaruka za ogisijeni nkeya, ku buryo ibinyabuzima bitagira ubuzima, kugira ngo bigere ku biryo bishya kandi nta ndwara. intego yo kubaho. Mubisabwa harimo gupakira vacuum mumifuka ya pulasitike, ipaki ya aluminiyumu, ibikoresho byibirahure, plastike hamwe nibikoresho bipakira, nibindi. Ibikoresho byo gupakira birashobora gutoranywa ukurikije ubwoko bwibintu. Kubera ko imbuto ari ibiryo bishya, biracyahumeka, kandi hypoxia nyinshi izatera indwara zifata umubiri. Kubwibyo, gupakira vacuum ntibikoreshwa cyane ku mbuto.

Igitekerezo n'imikorere

Gupakira Vacuum ni paki irinda ibicuruzwa kwanduza ibidukikije kandi ikongerera igihe cyibiribwa, bishobora kuzamura agaciro nubwiza bwibicuruzwa. Ubuhanga bwo gupakira Vacuum bwatangiye muri 1940. Kuva firime ya polyester na polyethylene ikoreshwa neza mugupakira ibicuruzwa mu 1950, imashini zipakira vacuum zateye imbere byihuse.

Mu rwego rwubuzima bwabantu nakazi kabo, ubwoko bwose bwapakiye vacuum bushobora kuboneka ahantu hose. Ibipfunyika byoroheje, umuyaga mwinshi, kubika neza, kurwanya ruswa, hamwe no gupakira ibintu bya pulasitike ya pulasitike irwanya ingese bikubiyemo imirima myinshi kuva ibiryo kugeza ubuvuzi, imyenda yo kuboha, kuva mu bicuruzwa bitunganijwe neza kugeza ku nganda zitunganya ibyuma na laboratoire. Kwiyongera kwinshi mubikoresho bipfunyika bya pulasitiki byateje imbere iterambere ryimashini zipakira plastike kandi zishyiraho ibisabwa hejuru.

Uburyo bwo gupakira vacuum: ikigamijwe ni ukugabanya umwuka wa ogisijeni uri muri paki, ukirinda kubora no kwangirika kwibiryo byapakiwe, gukomeza ibara nimpumuro nziza yibyo kurya, no kongera igihe cyo kubaho.

Igikorwa nyamukuru cyo gupakira vacuum ni ugukuraho ogisijeni kugirango ifashe kwirinda ibiryo kwangirika. Ihame riroroshye cyane, kubera ko kwangirika kwibiryo biterwa ahanini nibikorwa bya mikorobe, kandi kubaho kwa mikorobe myinshi (nk'ibumba n'umusemburo) bisaba ogisijeni. Nibyo, kandi gupakira vacuum ikoresha iri hame kugirango ikure ogisijeni muri Umufuka n'utugingo ngengabuzima, kugirango micro-ibintu bitakaza "ibidukikije byo kubaho". Ubushakashatsi bwerekanye ko: iyo umwuka wa ogisijeni uri mu mufuka wapakiye ari ≤1%, imikurire n’imyororokere ya mikorobe izagabanuka cyane, kandi iyo umwuka wa ogisijeni ari ≤ 0.5%, mikorobe nyinshi zizahagarikwa kandi zihagarike korora. .

Usibye kubuza gukura no kubyara mikorobe, vacuum deoxygenation ifite ikindi gikorwa cyingenzi cyo gukumira okiside y'ibiryo. Kuberako ibiryo byamavuta birimo aside irike idahagije, iba oxyde na ogisijeni, bigatuma ibiryo biryoha kandi bikangirika. Byongeye kandi, okiside itera kandi ibiryo Gutakaza vitamine A na C, ibintu bitajegajega mu ibara ryibiryo bigira ingaruka kuri ogisijeni, bigatuma ibara ryijimye. Kubwibyo, gukuramo ogisijeni birashobora kubuza neza ibiryo kwangirika no kugumana ibara ryabyo, impumuro nziza, uburyohe nagaciro kintungamubiri.

Igikorwa nyamukuru cyo gupakira umwuka wuzuye umwuka ntabwo ari umurimo wo kubungabunga ogisijeni gusa, ahubwo ni n'umurimo wo kurwanya umuvuduko, guhagarika umwuka no kubika neza. Irashobora kugumana neza ibara ryumwimerere, impumuro nziza, uburyohe, imiterere nubwiza bwibiryo igihe kirekire. agaciro k'imirire. Byongeye kandi, ibiryo byinshi ntibikwiriye gupakira vacuum ariko bigomba kuba byuzuyemo ifaranga rya vacuum. Nkibiryo byoroshye kandi byoroshye, ibiryo byoroshye guhuriza hamwe, ibiryo byoroshye guhinduka no gutakaza amavuta, ibiryo bifite impande zisharira cyangwa ubukana bwinshi buzacumita umufuka wapakiye, nibindi. Nyuma yibyo biryo byuzuyemo icyuho, umuvuduko wifaranga uri mumufuka wapakiye urakomera kuruta umuvuduko wikirere uri hanze yumufuka wapakiye kandi ntugire icyo uhindura mubitereko byapakiye.

Gupakira umwuka wuzuye umwuka wuzuye azote, dioxyde de carbone, gaze imwe ya ogisijeni cyangwa imvange ya gaze ebyiri cyangwa eshatu nyuma ya vacuum. Gazi ya azote ni gaze ya inert, ikora nk'iyuzuza kugirango igumane umuvuduko mwiza imbere mu gikapu kugirango wirinde umwuka uri hanze yumufuka kwinjira mu gikapu no kurinda ibiryo. Dioxyde ya azote irashobora gushonga byoroshye mu binure cyangwa mu mazi, kandi aside aside ya karubone yoroheje yazanwe no gushonga ibuza mircobial zimwe na zimwe nka bagiteri zidafite imbaraga. Umwuka wa ogisijeni urashobora kubuza gukura no kubyara kwa bagiteri za anaerobic, kugumana imbuto n'imboga bishya kandi bifite amabara, kandi umwuka wa ogisijeni mwinshi urashobora gutuma inyama nshya zitukura. Gushyashya kwimbuto n'imboga ntibitakaza imirire.

Igipimo cyo gusaba

1. Ibicuruzwa byakize: isosi, ham, bacon, inkongoro yumunyu, nibindi.

2.

3. Ibicuruzwa bya soya: tofu yumye, inkoko y'ibimera, paste y'ibishyimbo, nibindi.

4. Ibiribwa bitetse: inkoko ikaranze, inkongoro ikaranze, inyama zinka hamwe na sosi, ibiryo bikaranze, nibindi.

5. Ibyokurya byoroshye: umuceri, isafuriya itose ako kanya, imboga zitetse, nibindi.

6. Amabati yoroshye: imigano irasa mumazi meza, imbuto muri sirupe, igikoma-ubutunzi umunani, nibindi.
