Kana tichitaura nezve co-extrude firimu zvatiri kureva?Firimu ratinoshandisa rinogadzirwa sei?
Chikafu chekuisa firimuinogadzirwa nemaitiro maviri: Co-extrude uye Lamination.Nhasi isu tinonyanya kutaura nezve co-extruded firimu.Kune matatu akasiyana maitiro e-co-extrusion: kuvhuvhuta kuumba, kutonhora kwemvura uye kukandwa.
Saka, ndedzipi nzira dzekugadzirafirimu rekurongedza chikafu?
1. Blow nzira
Kuburikidza nemhepo inotonhorera kuita firimu pamusoro kutonhora, saka inogona kukurumidza kutonhora, yakapfava, yakatenderera yakatambanudzwa, kujeka kwayo kuri kushoma kutonhora kwemvura nekukandwa, asi kupfava nemafirimu zviri nani kugadzira pouches, nepo spherical kutambanudza kwemvura. kugadzirwa kwehigh-barrier food stretch filmductility ine go impact.
2. Mvura Inotonhorera
Kuburikidza nekubatana kwakananga kwemvura uye firimu pamusoro kutonhora, saka inogona kukurumidza kutonhora, spherical kutambanudza, kupfava kwayo kuri kushoma kunzira yekuyerera, asi kuve pachena kuri nani, nepo kutenderera kutenderera kwekugadzirwa kwe.high-barrier food stretch filmductility ine go impact.
3. Cast nzira
Kuburikidza nekutonhodza roller kutonhora, chikafu chakakwirira chipingamupinyi chakatambanudzwa firimu chakagadzirwa kwenguva yakareba chine chakananga kutambanudza, kuchinjika hakuna kutambanudza, iyo yakazara flatness yakanaka, kujeka ndeyechipiri kune nzira yekufuridza, asi kutambanudza ductility kuri nani.
Eleven-layer kuyerera co-extruded firimu uchishandisa kuyerera kunonoka maitiro, gumi nerimwe-layer firimu chimiro 1 nguva co-extrusion kuumba, kuumba semvura inopopoma mushure mekuyerera kunonoka kuyerera kudzika, mushure mekunge mvura inotonhorera inotonhora ichiita mupurasitiki firimu, nekuti iyo firimu yekurongedza chikafu pachayo haina kutambanudzwa, yakanaka ductility kuita, ndiyo yakanakira kutambanudza muchina wekugadzira firimu rakatambanudzwa, rinoiswa pabatch chikafu kurongedza, pane yechinyakare mhando yemuchina wevacuum, chengetedza manpower, yakanyanya kushanda.
Sechinhu chikuru chekushandiswa kwefirimu rekurongedza chikafu, zvakasiyana-siyana zvakasiyana-siyana zvinodiwa, zviri mukati zviri kurongedzerwa kubva zvakabikwa kusvika zvakabikwa, kubva pasi kusvika pakupisa kwepamusoro, kubva kune nyore kusvika kune uori muchero mutsva kusvika kunzungu dzakaoma, kubva kumabhegi ekuputira vacuum kusvika kumabhegi ekuputira inflatable, inovhara huwandu hwemabhegi ekurongedza. .
1. Zvido zvekuzviparadzanisa nevamwe:Mazhinji echikamu chekudya akapfuma mumafuta nemafuta, mafuta nemafuta zvinotarirwa kuoxidation uye kuderera, saka izvo zvinodikanwa zvakanyanya zveokisijeni barriers, iyofirimu rekurongedza chikafumukati mwando kuwedzera kana kuderera zvinodiwa zvakare zvikuru kwazvo.
2. Kuita mwando:chikafu zvese zvine hunyoro chaihwo, kana iyo yekurongedza yasarudzwa, kana iri mamiriro ekugadzirisa chikafu, fomura inoramba isingachinji, hunyoro hwechikafu hunochinja zvishoma.Kana mamiriro acho achinge achinja, zvinokanganisa zvakananga kukosha kwehunyoro hwechikafu, uye hunyoro ndechimwe chezvinhu zvakakosha zvinokonzeresa kudzikira kwechikafu, chero paine humwe hunyoro hwemukati, hutachiona hunogona kukura.Pakudya kwakasiyana kwehunyoro, zvinhu zvakasiyana uye nzira dzinofanirwa kushandiswa.
a.Unyoro hushoma hwekuita chikafu.Utachiona hahukwanisi kurarama mukunyorova kwechikafu chisingasviki 0.65, nekuda kwekunyorova kwechikafu chisingasviki 0.60 chakaoma, chero bedzi chinogona kuchengetwa chakaoma kwenguva yakareba chinogona kunge chisina kuparara kwechikafu kunokonzerwa nebhakitiriya.
b.Chikafu chine hunyoro hwepakati.Zvekuita mwando mu 0.60-0.90 yepakati mwando chikafu, kuchengetedza mhando yekudya nzira ndedzinotevera,vacuum packaging, nitrogen packaging, deoxidizer packaging, nezvimwewo, yakaiswa mumafuta echikafu oxidative deterioration, kupera kwechikafu, nezvimwe.
c.Unyoro hwepamusoro hwekuita chikafu.Kune hunyoro hwekuita mu 0.9-1.0 yakawanda-unyoro system chikafu, nzira dzekuchengetedza mhando: 100 ℃ kana kupfuura kudziyisa sterilization, kushandiswa kwehydrogen peroxide, mwaranzi uye kumwe kuvharisa kweaseptic packaging.
3. Chikafu kurongedza firimu inflatable yekurongedza basa:Basa re inflatable packaging nderokuwedzera hupenyu hwesherufu, rudzi rwe inflatablemabhegi ekurongedzanezvinodikanwa zvakasiyana.
4. Cereal kurongedza bhegi zvinodiwa:Zviyo zvine simba rekufema, tsanga dzakasiyana paiyo okisijeni adsorption inosiyana zvakanyanya, mumasaga ezviyo ekurongedza, inogona kushandiswa mune yakanakisa yekuparadzanisa yekudya yekurongedza firimu izere neokisijeni kuchengetedza zvirinani zvechikafu inflatable masaga ekurongedza.
5. Vacuum zvinodiwa:Yakasimudzwa yakarongedza yakasarudzika okisijeni, hunyoro-humbowo, zvese kuchengetedza kunaka kwezvinhu uye kuita kuti kutaridzika kwezvinhu kuve kwakanaka, nerupo.
