Isingeniso Sesithombe Esifakiwe Somuntu Siqu Sokubanda Okusheshayo (IQF).

Isingeniso se-Individual Quick Freezing (IQF)

Incazelo emfushane:

I-Individual Quick Freezing (IQF) ubuchwepheshe obuthuthukisiwe be-cryogenic obuqandisa ukudla ngakunye ngokushesha, buvimbele ukwakheka kwekristalu yeqhwa nokugcina ukuthungwa, ukunambitheka, nobuqotho bokudla okunempilo. Ngokungafani nezindlela zokuqandisa ngobuningi, i-IQF iqinisekisa ukuthi iyunithi ngayinye (isb., amajikijolo, izimfanzi, noma ucezu lwemifino) ihlala ihlukene, ifinyelela izinga lokushisa elingu--18°C phakathi kwemizuzu engu-3–20 kuye ngejometri yomkhiqizo.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izinhlobo Zesistimu ye-IQF Eyisisekelo

Incazelo yemininingwane

1. Iziqandisi Zombhede Ezinamanzi:

● Isebenzisa umoya obandayo oya phezulu (-35°C) ukumisa imikhiqizo emincane efana neyunifomu (isb., uphizi, izaqathi ezisikiwe).
● Izinga lokuqandisa: 5–10 imizuzu yezinhlayiya ezingu-10–15 mm.

2.Spiral Freezers:

● Amasistimu aqhutshwa ngamabhande ezinto ezithambile/ezinkulu (isb, ukudla kwasolwandle, izithelo ezisikiwe).
● Isebenza ku -40°C ngezivinini zebhande ezilungisekayo (10–60 mins cycle).

3. Iziqandisi zeTunnel:

● Idizayini ewumugqa wokucubungula umthamo omkhulu (amathani angu-2–5/ihora).
● Ilungele izinkukhu ze-IQF noma ukudla okuphekwe ngaphambilini.

4. Iziqandisi Zokuvimba:

● Amajethi omoya anesivinini esikhulu (15–30 m/s) angena endaweni yomkhiqizo.
● Yehlisa isikhathi sokuqandisa ngo-30% ezintweni eziyisicaba (isb., ama-patties, ama-fillet).

Ububanzi bohlelo lokusebenza

Incazelo yemininingwane

● Ukudla kwasolwandle:Ama-shrimp, ama-scallops, nezingxenye zezinhlanzi zigcina umswakama ongu-95%.
● Izithelo/Imifino:Amajikijolo, izingcezu zikamango, nemifino enamahlamvu igcina ukwakheka kwamangqamuzana (ukulahlekelwa kwevithamini C <8%).
● Ukudla Okulungisiwe:I-IQF pizza toppings, amakhambi, nezinto ezithosiwe zinika amandla ukukhiqizwa okufika ngesikhathi.
● Indawo yokubhaka:Izingcezu zenhlama eqandisiwe ngazinye zivimbela ukunqwabelana ngesikhathi sokuhlolwa.

Izinhlelo zesimanje ze-IQF zihlanganisa ukusebenza kahle kokugeleza komoya okuqhutshwa yi-AI kanye namamojula okubuyisela amandla, kuzuzwe ukonga amandla okungama-25-40% uma kuqhathaniswa neziqandisi ezivamile. Ukuthobelana ne-HACCP kanye ne-FDA 21 CFR Ingxenye 113 kuqinisekisa ukuphepha kokudla, kuyilapho ukubanda okusheshayo (-1°C/min rate) kuvimbela ukukhula kwe-microbial (TPC <10⁴ CFU/g). Njengoba isidingo somhlaba wonke sokudla okulula sikhula, i-IQF isalokhu ibalulekile ekulinganiseni ukulondolozwa kwekhwalithi nokwehla kwezimboni.
