Retort resistance packaging, inonziwo soft can, ndiyo inoveli yekurongedza mhando iyo yakawana kukurumidza kukura mukati memakore maviri apfuura.Iri nyore kushandisa ndiro rinotonhora uye rinopisa rinobikwa chikafu.Kuchengetedza kwenguva yakareba pasi pekushisa kwekamuri pasina kuparara ndiyo maitiro ayo akatanhamara.Uku kurongedza kunoshandiswa zvakanyanya kune chikafu, delicatessen, nezvimwewo, uye zvakare inoshandiswa muzvinwiwa, mashed mbatatisi, zviyo uye zvichingodaro muWestern Europe.

Kuti uchengetedze zvirinani zviri mukati, iyo yakajairwa retort kuramba kurongedza mumusika inogamuchirwa yakanyanya tembiricha (121 ℃) sterilization kazhinji, kuitira kuti ive nechokwadi chesherufu mumwedzi mitanhatu.Nekuvandudzwa kwemararamiro evanhu, zvinodikanwa zvekuchengetedzwa kwemapaketi ezvekudya zvinokwira nekukwira.Nzira yekuwedzera sei hupenyu hwesherufu uye kuwedzera kunaka uye kuravira kwezviri mukati kwave kutarisisa kunopisa.

Iye zvino mafekitori mazhinji anochinjika ekurongedza anowanzo kutora nzira dzinotevera kuti aone hupenyu hurefu hwesherufu.

1. Kuwedzera retort tembiricha.Zviri mukati zvinowedzerwa sterilized pasi pe135 ℃.
2. Kuvandudza kushanda kwepamusoro barriers.Yakakwira chipingamupinyi haisi kungodzikisa kurasikirwa kwezviri mukati flavour, asi zvakare inogona kudzivirira kuparara.

Nekudaro, nekuzivikanwa kwemaovheni emicrowave, iyo yakakwira chipingamupinyi & yakanyanya tembiricha microwavable packaging yakagadzira nekukurumidza.Zvimwe zviri nyore uye nekukurumidza nzira dzekubikisa dzinoda zvekurongedza zvinhu kuti zviite mamwe mabasa.Kudziya kwakananga muovheni yemicrowave harisi chete basa rerudzi urwu rwekuvharira yakakwira & yakakwira tembiricha yekurongedza zvinhu, asiwo maitiro asingadzivisike ekusimudzira.

Izvo zvechinyakare zvipingamupinyi zvinhu PVDC, EVOH, aluminium foil uye simbi firimu.Sechinhu chakakwira chipingamupinyi chekurongedza, PVDC inoshandiswa zvakanyanya.Asi marara ayo achakonzera kusvibiswa kwezvakatipoteredza panguva yekupisa kurapwa.Iko kuvharidzira kuita kweEVOH kunorambidzwa zvakanyanya nenharaunda.Kana hunyoro huri> 60%, iyo yekuvharira kuita inoderera zvakanyanya.Aluminium foil ine opaque, kushandiswa kwezviwanikwa kwakakura, kuri nyore kuunyana uye kuvharira microwave kutapurirana.Iyo firimu yesimbi yakaoma kudzoreredza, opaque, yakashata microwave permeability, uye iri nyore kupepeta kana uchibika pakupisa kwakanyanya.

Zvichienderana nenyaya dziri pamusoro, indasitiri yekugadzira chikafu inosimudza zvinodikanwa zvekutakura zvinhu, iyo microwavable yekurongedza inofanirwa kunge iine yakanakisa chipingamupinyi kuita, pachena uye inogona kudzoserwa pasi pe135 ℃.
