Introduction to Individual Quick Freezing (IQF)

ʻO ka wehewehe pōkole:

ʻO ka Individual Quick Freezing (IQF) kahi ʻenehana cryogenic holomua e hoʻokuʻu koke i nā meaʻai i kēlā me kēia, e pale ana i ka hoʻokumu ʻana o ka hau aniani a mālama i ke ʻano, ka ʻono, a me ka pono o ka meaʻai. ʻAʻole like me nā ʻano hoʻoheheʻe nui, hoʻopaʻa ʻo IQF i kēlā me kēia ʻāpana (e laʻa, ka hua, ka ʻōpae, a i ʻole ka ʻāpana ʻai meaʻai) e noho kaʻawale, e loaʻa ana nā mahana kumu o -18°C i loko o 3-20 mau minuke ma muli o ka geometry huahana.

Nā ʻano ʻōnaehana IQF kumu mua

wehewehe kikoʻī

1.Fluidized moena pahu hau:

● Hoʻohana i ka ea anu i luna (-35°C) no ka hoʻokuʻu ʻana i nā huahana liʻiliʻi like ʻole (e laʻa, ka pī, kāloti ʻoki ʻia).
● Laki hau hau: 5–10 minuke no 10–15 mm mau ʻāpana.

2. ʻO nā mea hoʻoheheʻe liʻiliʻi:

● Pūnaehana kāʻei kāʻei no nā mea maʻalahi/nui (e laʻa, iʻa iʻa, nā huaʻai i ʻoki ʻia).
● Hoʻohana ma -40°C me ka wikiwiki o ke kāʻei hiki ke hoʻololi ʻia (10-60 mins cycle).

3. Tunnel Freezers:

● Hoʻolālā laina no ka hana kiʻekiʻe (2-5 tons / hola).
● He kūpono no ka ʻai moa i hoʻomoʻa mua ʻia.

4. Impingement Freezers:

● Hoʻokomo ʻia nā mokulele mokulele kiʻekiʻe (15–30 m/s) i nā ʻili o nā huahana.
● Ho'emi i ka manawa maloo e 30% no na mea palahalaha (e la'a, patties, fillets).

● iʻa kai:ʻO ka ʻōpae, ka ʻili, a me nā ʻāpana iʻa he 95% o ka wai.
● Nā Huaʻai/Laʻai:ʻO nā huaʻai, nā ʻāpana mango, a me nā lau ʻōmaʻomaʻo e mālama i ke ʻano o ke kelepona (ʻoi aku ka huaora C <8%).
● Nā meaʻai i hoʻomākaukau ʻia:Hiki i ka IQF pizza toppings, nā mea kanu, a me nā mea paʻi paʻi ʻia e hiki ai ke hana pono i ka manawa.
● Pāʻai:ʻO nā ʻāpana palaoa maloʻo paʻakiki e pale i ka pipili ʻana i ka wā e hōʻoia ai.

Hoʻohui nā ʻōnaehana IQF o kēia manawa i ka hoʻonui ʻana i ka ea a me ka hoʻolaʻa ʻana i ka ikehu modula AI, e loaʻa ana i ka 25-40% ka mālama ʻana i ka ikehu ma mua o nā pahu manuahi maʻamau. ʻO ka hoʻokō me ka HACCP a me FDA 21 CFR Māhele 113 e hōʻoia i ka palekana o ka meaʻai, ʻoiai ka wikiwiki o ka hau (-1°C/min rate) ke keʻakeʻa nei i ka ulu microbial (TPC <10⁴ CFU/g). Ke ulu nei ka makemake o ka honua no nā meaʻai maʻalahi, hoʻomau ka IQF i ke kaupaona ʻana i ka mālama ʻana i ka maikaʻi me ka scalability ʻoihana.
