Pamene kuzizira zakudya, zone kuchokera pafupifupi.0 C mpaka -5 C amatchedwa pazipita ice crystal generation zone.Kaya kutentha kumeneku kumayenera kudutsa mwachangu kapena pang'onopang'ono kumakhudza kukula ndi mtundu wa makristasi oundana ndipo zimatsimikizira kapangidwe ka zakudya zowundana.
Kuzizira pang'onopang'ono kumatulutsa makristasi ocheperako komanso akulu;Zomwe zimapangidwa pakati pa ma cell zimawononga kapangidwe kake, ndikuwonjezera kachulukidwe kakang'ono pakuzizira.M'malo mwake, kuzizira kofulumira kumapanga makristasi abwino ambiri ndipo sikuwononga maselo.(Onani Frozen Foods Handbook lofalitsidwa ndi Korin Shoin).

● Nayitrojeni wamadzimadzi(liquefied carbon dioxide) ndi mpweya wotentha kwambiri pa -196 C(-78C).
● Zakudya zimatha kuziunda nthawi yomweyo popopera mankhwala a nitrogen (liquefied carbon dioxide).
● Kuzizira kofulumira sikuwononga maselo a chakudya.
● Kuzizira kofulumira kwambiri sikuwononga kukoma kwa zakudya kapena kuzisintha, kumasungabe khalidwe lake.
● Kukoma kwake kumasungidwa kwa nthawi yaitali.
● Drip outflow ndi kuyanika kuwonongeka kungapewedwe, kulola kutaya pang'ono kwa mankhwala.
Komanso
● Kutsika mtengo kwa makinawo poyerekezera ndi kuphulika kwa mpweya wamba.
● Makina osavuta komanso osavuta kukonza.
● Mufiriji wa bokosi ndi mufiriji wamtundu wa batch kuti aziziziritsa/kuziundana mwachangu zakudya.
● Pogwiritsira ntchito liquefied carbon dioxide kapena liquid nitrogen monga refrigerant, mufiriji wa bokosi amaundana msanga mkati mwa mufiriji kutentha kwa mkati mwa -60 C mpaka-100 C.
● Zonse zamkati ndi kunja kwa mufiriji wa bokosi zimapangidwa ndi zitsulo zosapanga dzimbiri, zomwe zimapangitsa kuti zisawonongeke komanso kuzizira.
● Chokupiza chokakamiza chimazizira mwachangu mkati mwafiriji kuti chitsimikizire kuti kutentha kuli kofanana.
● Yokhoza kuyika/kutsitsa zogwiriziza za alumali pamodzi ndi chimango.(Njira)
