Itreyi yemephu

Yintoni itreyi yemephu?

Itreyi yemephu ibhekisa kwitreyi yokupakisha eguqulweyo esetyenziselwa ukwandisa ubomi beshelufa yokutya okutshabalala.
Ezi transy zenzelwe ukubamba iimveliso kwimeko etywiniweyo apho umoya ngaphakathi utshintshwe khona umxube wegesi-ioksijini, i-carbon diokside, kunye nenitrogen.
Le ndlela yokupakisha isetyenziselwa inyama entsha, ukutya kwaselwandle, iinkukhu, kunye nokuyila ukutya.

Isebenza njani imephu yetreyi?

Imephu isebenza ngokugcina ubume obuthile begesi ejikeleze imveliso yokutya.
Le moya eguqulweyo icothisa ukukhula intsholongwane kunye ne-oxidation, igcina ukutsha, umbala, kunye nokuthathwa kokutya.
Itreyi itywinwe itywinwe ngefilimu ephezulu yokugcina indawo yangaphakathi iye yavula ngumthengi.

Zeziphi izixhobo ezisetyenziswa kwii-trays zemephu?

Iitreyi zemephu zenziwa kwizinto eziphezulu ezifana ne-Pet, i-PP, okanye i-PS, zihlala zingamacandelo omninzi okanye iingubo zokuthintela ukungqubana kwegesi.
Ezinye iitreyi zibandakanya i-EvOH (i-Ethylene vinyl yotywala) ye-biny yegesi enkulu.
Ezi zixhobo zikhethwe ukuqinisekisa ukhuseleko lwemveliso, ukuqina, kunye nokuhambelana koomatshini bokutywina.

Zeziphi iintlobo zokutya eziqhele ukupakishwa kwimephu?

Iitreyi zemephu zisetyenziselwa inyama entsha, iinkukhu, iintlanzi, ukutya kwaselwandle, iisoseji, itshizi, izinto ezifunekileyo, kunye nokutya okutsha.
Banceda abathengisi bodwa banikezela ngobomi beshelufa engaphezulu ngaphandle kokusetyenziswa kwezinto ezizizo, zenza ukuba zilungele ukupakishwa kokutya.

Ngaba imephu yemephu ihlaziywa?

Iindlela ezininzi zemephu azinakuphinda zisetyenziselwe ngokuyinxalenye, kuxhomekeke kubume bezinto ezibonakalayo kunye namaziko okuphinda asebenze kwakhona.
Itreyitha yezinto ezizodwa ezinje nge-mono-pet okanye i-mono-pp inee-eco-friend kwaye iphinde isetyenziselwe ukuthelekiswa kweetreyi ze-rays ezininzi.
Iitreyi zemephu ezinokuphinda zisebenze zisiba yimfuneko njengenxalenye yezisombululo zokutya ezinzileyo zokutya.

Zeziphi iifilimu zokutywina ezisetyenziswa ngeetreyi zemephu?

I-imeyili yemephu itywinwe kunye nefilimu ephezulu yokuqhekeza iifilimu ezixhaphaza-ukunyangwa kunye negesi-qinisa.
Ezi filimu zinokubonisa iipropathi ze-Anti-FOG, ukusebenza ngokulula, okanye uphawu oluprintiweyo.
Ukukhetha ifilimu ngokufanelekileyo kubalulekile ukugcina imeko eguqukayo kunye nokuqinisekisa ukubonakala kwemveliso kunye nokulula.

Ngaba iitreyi zemephu zingasetyenziswa ngoomatshini bokupakisha ezenzekelayo?

Ewe, iitreyi zemephu ziyahambelana noomatshini bokutywina ngokuzenzekelayo kunye neenkqubo zokugungxula igesi.
Ziinjineli zemigca yokupakisha ephezulu, iqinisekisa inkqubo engaguqukiyo neyococeko.
Oku kwenza ukuba ukutya kwemaphu kulandelela ukhetho oluphambili kwiiprosesa zokutya kunye neepali ezikhulu zenyama.

Ngaba iitreyi zemephu zilungele ukugcinwa kwe-frozen?

Ngelixa iitreyi zemephu ziyilelwe ngokuyintloko zokugcina ifriji, iintlobo ezininzi zikhuselekile.
Iitreyidi ze-freezer zenziwa kwizinto ezifana ne-cgner okanye i-PP ekhethekileyo ekwakukuko ukuqhekeza amaqondo obushushu asezantsi.
Soloko uqinisekisa iinkcukacha ezibonakalayo ngaphambi kokusebenzisa i-imeyili yemephu yepakethi yokutya eqaqambileyo.

Yeyiphi ubungakanani kunye neemilo ezikhoyo zokuqhuba ii-imephu?

Iitreyi zemephu ziza ngoluhlu olubanzi lwe-SEPERORY, ubungakanani besiko, kubandakanya uxande, isikwere, kunye neetreyitha zendawo.
I-SARIT zihlala zikhethwe ngokusekwe kubunzima beSahlulo, uhlobo lwemveliso, kunye neemfuno ze-Shellate.
Ipakisi yesiko lemephu inokulungelelaniswa ukuhlangabezana nokuhlanganisa uphawu okanye iinjongo zomsebenzi, ezinje ngeempawu okanye ezibonakalayo.

Ngaba ii-imeyili zemephu zihlangabezana nemigangatho yokhuseleko yokutya?

Ewe, zonke iitreyi zemephu ezisetyenziswa kwizicelo zokutya kufuneka zihambelane neMigaqo yeBanga lokutya efana ne-FDA, i-EU 10/2011, okanye eminye imigangatho yesizwe.
Benziwa kwiindawo ezicocekileyo kwaye bakhuselekile ekunxibelelaneni ngokuthe ngqo.
Abavelisi abaninzi bakwabonelela ngamaxwebhu okulandela kunye nokwakhiwa komgangatho xa bekufuneka.
