Yintoni iVacuum Packaging

Ukupakishwa kweVacuum, okwabizwa ngokuba yi-decompression packaging, kukukhupha wonke umoya kwisingxobo sokupakisha kwaye uyitywine ukugcina inqanaba eliphezulu loxinzelelo engxoweni. Ukunqongophala komoya kufana nomphumo we-oksijini ephantsi, ukwenzela ukuba i-microorganisms ingabi neemeko zokuphila, ukuze kuzuze ukutya okutsha kwaye akukho sifo. injongo yokwenzeka. Izicelo zibandakanya ukupakishwa kwe-vacuum kwiingxowa zeplastiki, i-aluminium foil packaging, i-glassware, iplastiki kunye ne-composite material packaging, njl. Izinto zokupakisha zingakhethwa ngokohlobo lwezinto. Ekubeni isiqhamo kukutya okutsha, sisaphefumla, kwaye iqondo eliphezulu le-hypoxia liya kubangela izifo ze-physiological. Ke ngoko, ukupakishwa kwevacuum akusetyenziswa kancinci kwiziqhamo.

Ingcamango kunye nomsebenzi

Ukupakishwa kweVacuum yiphakheji ekhusela iimveliso ekungcolisekeni kwendalo kunye nokwandisa ixesha leshelufu lokutya, elinokuphucula ixabiso kunye nomgangatho weemveliso. Itekhnoloji yokupakisha iVacuum yaqala ngeminyaka yoo-1940s. Ekubeni iifilimu zeplastiki ze-polyester kunye ne-polyethylene zasetyenziswa ngempumelelo kwi-package yempahla ngo-1950, oomatshini bokupakisha be-vacuum baphuhliswe ngokukhawuleza.

Kwintsimi yobomi kunye nomsebenzi wabantu, zonke iintlobo zokupakishwa kweplastiki ye-vacuum zifumaneka kuyo yonke indawo. Ikhaphukhaphu, ingena moya, igcina ukutsha, ichasene nomhlwa, kunye nokupakishwa kweplastiki yokuvala umhlwa igubungela iindawo ezininzi ukusuka ekutyeni ukuya kwiyeza, iimpahla ezinithiweyo, ukusuka kwimveliso yemveliso echanekileyo ukuya kwizityalo ezisebenza ngesinyithi kunye neelebhu. Ukusetyenziswa okukhulayo kokupakishwa kweplastiki yokucoca iplastiki kukhuthaze ukuphuhliswa koomatshini bokupakisha beplastiki kwaye kubeka phambili iimfuno eziphezulu kubo.

Indlela yokupakisha i-vacuum: injongo kukunciphisa umxholo we-oksijeni kwiphakheji, ukuthintela ukubunjwa kunye nokuwohloka kokutya okupakishweyo, ukugcina umbala kunye nevumba lokutya, kunye nokwandisa ubomi beshelufu.

Umsebenzi ophambili wokupakishwa kwevacuum kukususa ioksijini ukunceda ukuthintela ukuwohloka kokutya. Umgaqo ulula, kuba ukubola kokutya kubangelwa ikakhulu yimisebenzi ye-microorganisms, kwaye ukusinda kwee-microorganisms ezininzi (ezifana nokungunda kunye negwele) kufuna i-oksijini. Ewe, kwaye ukupakishwa kwevacuum kusebenzisa lo mgaqo ukukhupha ioksijini kwindawo Ingxowa yokuPakisha kunye neeseli zokutya, ukwenzela ukuba i-micro-izinto zilahlekelwe "indawo yokuhlala" yazo. Iimvavanyo ziye zabonisa ukuba: xa i-oksijeni yoxinaniso kwi-packaging bag i-≤1%, ukukhula kunye nesantya sokuvelisa i-microorganisms kuya kuhla ngokukhawuleza, kwaye xa i-oxygen concentration i-≤0.5%, ezininzi ze-microorganisms ziya kuvinjelwa kwaye ziyeke ukuzala. (Qaphela: ukupakishwa kweVacuum akukwazi kuthintela ukukhula kwebhaktheriya ye-anaerobic kunye nokuwohloka kokutya kunye nokuguquka kombala okubangelwa kukutshintsha kwe-enzyme, ngoko ke kufuneka kudityaniswe nezinye iindlela ezincedisayo, ezifana nefriji, ukukhenkceza ngokukhawuleza, ukuphelelwa ngamanzi emzimbeni, ubushushu obuphezulu, inzalo ye-radiation, sterilization ye-microwave, ityuwa ekhethiweyo njl.

Ukongeza ekuvimbeleni ukukhula kunye nokuveliswa kwe-microorganisms, i-vacuum deoxygenation inomnye umsebenzi obalulekileyo wokukhusela i-oxidation yokutya. Ngenxa yokuba ukutya okunamafutha kuqulethe isixa esikhulu se-unsaturated fatty acids, i-oxidized yi-oksijini, yenza incasa yokutya kunye nokuwohloka. Ukongezelela, i-oxidation nayo yenza ukutya Ukulahleka kwevithamini A kunye no-C, izinto ezingazinzanga kumbala wokutya zichaphazelekayo yi-oksijini, okwenza umbala ube mnyama. Ke ngoko, ukususwa kweoksijini kunokuthintela ngokufanelekileyo ukutya ekuwohlokeni kwaye kugcinwe umbala, ivumba, incasa kunye nexabiso lesondlo.

Umsebenzi oyintloko we-vacuum-filled packaging ayikona nje kuphela umsebenzi wokugcinwa kwe-oksijini, kodwa kunye nomsebenzi wokuchasana noxinzelelo, ukuvimbela umoya kunye nokugcinwa ngokutsha. Inokugcina ngokufanelekileyo umbala wokuqala, ivumba, incasa, imilo kunye nomgangatho wokutya ixesha elide. ixabiso lesondlo. Ukongeza, ukutya okuninzi akufanelanga ukupakishwa kwevacuum kodwa kufuneka kufakwe i-vacuum inflation. Okufana crispy kunye ukutya eethe-ethe, ukutya lula agglomerate, ukutya lula deform kunye nokulahlekelwa ioli, ukutya kunye imiphetho ebukhali okanye ubulukhuni obuphezulu oya kugqobhoza ibhegi yokupakisha, njl. Emva kokuba ukutya kufakwe i-vacuum-packed, uxinzelelo lokunyuka kwamaxabiso ngaphakathi kwengxowa yokupakisha yomelele ngaphezu koxinzelelo lomoya ocoliweyo onokuthi uthintele ngaphandle kwengxowa yokutya, enokuthi ithintele isikhwama sokutya ngaphandle kwe-packform. phantsi koxinzelelo ngaphandle kokuchaphazela ukubonakala kunye nomhlobiso wokushicilela wesikhwama sokupakisha.

I-vacuum ezaliswe yi-vacuum yokupakisha igcwele i-nitrogen, i-carbon dioxide, i-oxygen igesi enye okanye umxube weegesi ezimbini okanye ezintathu emva kokucoca. Igesi ye-nitrogen igesi ye-inert, esebenza njengokuzaliswa kokugcina uxinzelelo oluhle ngaphakathi kwesikhwama ukukhusela umoya ongaphandle kwesikhwama ukuba ungene kwisikhwama kunye nokukhusela ukutya. I-nitrogen dioxide inokunyibilika lula emafutheni okanye emanzini, kwaye i-asidi yekhabhoni ekhaphukhaphu eveliswa koku kunyibilika ithintela ezinye ii-mircobials ezifana nokungunda kunye neebhaktheriya ezibolileyo. Ioksijini yayo inokuthintela ukukhula kunye nokuzala kwakhona kwebhaktheriya ye-anaerobic, igcine iziqhamo kunye nemifuno zintsha kwaye zinemibala, kwaye ukuxinana okuphezulu kweoksijini kunokugcina inyama entsha ibomvu. Ukutsha kweziqhamo kunye nemifuno akuphulukani nesondlo.
