Muzochita zamakono, mawu akuti IQF amaimira "mwachangu mwachangu."
Zakudya za IQF zimadziwika kuti chakudya chilichonse chimakhala chozizira mosiyana ndi ena onse. Kotero, mwachitsanzo, thumba la nandolo za IQF sizimangokhala ndi nandolo yowonongeka, komabe, nthanga iliyonse yowonongeka imatuluka mkati mwa thumba. Mwachiwonekere, izi zimapangitsa zakudya za IQF kukhala zosavuta kugwira ntchito.
Mawu ena a IQF ndi "kuwala-mazira."
Zitsanzo za zakudya za IQF ndi zipatso monga blueberries, strawberries, ndi yamapichesi; masamba monga chimanga, nandolo, ndi nyemba zobiriwira ; Nsomba monga shrimp ndi scallops ; kapena nkhuku, monga mawere a nkhuku .
Ngakhale nkhuku zonse, monga turkeys ozizira , zimagwiritsidwa ntchito pogwiritsa ntchito njira ya IQF.
Momwe chakudya chimakhalira mu njira ya IQF kumaphatikizapo kutumiza zakudya zamtundu uliwonse pamtundu wa bult conveyor mu friji yozizira yomwe imatulutsa chinthucho mofulumira kwambiri. Chifukwa chakuti zakudya zimakhala zosiyana akamalowa, zimakhala zosiyana akatha kuzizira.
Kodi IQF Ikugwira Ntchito Bwanji?
Ndondomekoyi inayambitsidwa ndi katswiri wa sayansi ya zamoyo amene, pamene kupha nsomba ku Canada pa madigiri 40-pansi-zero-tsiku, anaona kuti nsomba yomwe anaichotsa m'madzi pansi pa ayezi ikanawombera mwamphamvu pamene iye anawaponya pa chisanu. Chodabwitsa kwambiri, komabe, chinali chakuti zina mwa nsombazi zikanakhalabe zamoyo pambuyo poti zidzulidwa.
Zotsatira zodabwitsa izi zikugwirizana ndi mfundo yakuti pamene chinachake chimathamanga msangamsanga, chimapanga makina ang'onoang'ono a madzi oundana kusiyana ndi pamene imazizira pang'onopang'ono. Makristalu akuluakulu a ayezi amawononga maselo ndi makoswe. Pamene nsombazi zinkazizira kwambiri m'madzi makumi anayi pansipa, zitolirozi zinali zazing'ono kwambiri kuti zisawononge makoma, kotero nsomba zina zidapulumuka.
Mfundo yomweyi ikugwira ntchito ndi IQF kapena zakudya zozizira. Chifukwa chake zakudya zimanyoza pamene zidazizira chifukwa chakuti makulu akuluakulu a ayezi amawononga makutu a chakudya, kotero kuti imakhala yowuma komanso yowuma, chifukwa makwinya a ayezi aphwanyidwa, ndikukakamiza kuti madzi a chakudya achoke m'makoma.
Kuzizira mofulumira zakudya kumapanga makina osungunuka a ayezi, ndipo motero sawononge mafinya a chakudyacho.
IQF Imachepetsa Ice Crystallization
Mwapadera, izi ndi chifukwa mazira a ayisikili okha ndi mawonekedwe pakati pa 31 ndi 25 madigiri Fahrenheit. Ndipo patapita nthawi chakudya chimatha mu kutentha kwapakati, mitsuko yowonjezera yowonjezera idzapanga.
Chinsinsi cha IQF chikufulumizitsa chakudya kupyolera mu 31 mpaka 25 F kutentha komweko mwamsanga.
Mwachitsanzo, zingatenge maola khumi kuti awononge nsomba pamadzi ozizira (mwachitsanzo, kuziyika mufiriji kunyumba). Koma pogwiritsa ntchito luso la IQF, lingatenge mphindi 90 zokha. Koma mopambanitsa, mmalo mokhala maola asanu ndi limodzi (khumi mwa khumi) pa malo okwana 31 mpaka 25 mu njira yowonongeka, imangokhala mphindi 25 pamenepo pogwiritsa ntchito IQF.
Mwa njirayi, dzina la sayansi ya sayansi ya usodzi ya ayezi amene anapeza ndikugwiritsa ntchito njirayi ku zakudya zamkati zogulitsidwa: Clarence Birdseye.
