Umugqa Wokukhiqiza Ukufinyezwa Kwemifino
Ukufinyeza kwemifino kunamafutha aqinile kancane enziwe ngamafutha emifino ngezinqubo ezifana ne-hydrogenation, ukuxuba, kanye ne-crystallization. Kusetshenziswa kabanzi ekubhakeni, ekuthoseni, nasekucubunguleni ukudla ngenxa yokuqina kwayo okuphezulu kanye nokuthungwa okubushelelezi. Umugqa wokukhiqiza ukufinyeza kwemifino uhilela izigaba eziningana ezibalulekile ukuqinisekisa ikhwalithi, ukuhambisana, kanye nokuphepha kokudla.
1. Izinqubo Eziyinhloko Zokukhiqiza Ukufinyezwa Kwemifino
(1) Ukulungiswa Nokuhlanganiswa Kwamafutha
- Amafutha Emifino Acwengisisiwe:Amafutha ayisisekelo (ubhontshisi, isundu, imbewu yekotini, noma i-canola) ayahlungwa ukuze kususwe ukungcola.
- Ukuhlanganisa:Amafutha ahlukene axutshwa ukuze kufezwe ukuthungwa okufiselekayo, iphuzu lokuncibilika, kanye nokuqina.
(2) I-Hydrogenation (Ongakukhetha)
- I-hydrogenation engaphelele ingasetshenziswa ukwandisa ukuzinza kanye nokuqukethwe kwamafutha aqinile (yize abakhiqizi abaningi manje besebenzisa izindlela ezingezona i-hydrogenated ngenxa yokukhathazeka ngamafutha e-trans).
- Igesi ye-Catalyst ne-Hydrogen:Uwoyela uphathwa nge-nickel catalyst kanye negesi ye-hydrogen ngaphansi kokushisa okulawulwayo kanye nengcindezi.
(3) Ukuxubana Kwe-Emulsification Nezithasiselo
- Ama-emulsifier (isb., i-lecithin, i-mono- kanye ne-diglycerides) ayengezwa ukuze kuthuthukiswe ukuthungwa.
- Izithako zokuvikela, ama-antioxidants (isib. i-TBHQ, i-BHA), kanye nezinongo zingafakwa.
(4) Ukupholisa Nokwenza Ikristalu (Ukushisa)
- Ingxube yamafutha ipholiswa ngokushesha ku-i-scraped surface heat exchanger (SSHE)ukwakha amakristalu amafutha aqinile.
- Izitsha Zokwenza Amakristalu:Umkhiqizo ugcinwa ngaphansi kwezimo ezilawulwayo ukuze kuthuthukiswe ukuhambisana okufanele.
(5) Ukupakisha
- Ukufinyeza kugcwele ngaphakathiamabhakede epulasitiki, amabhakede, noma izitsha zokufaka izinto ezinkulu zezimboni.
- Ukuhlanza nge-nitrogen kungasetshenziswa ukwandisa isikhathi sokuphila kweshalofu.
2. Imishini Eyinhloko Emugqeni Wokukhiqiza Imifino Efushane
| Imishini | Umsebenzi |
| Amathangi Okugcina Uwoyela | Gcina amafutha emifino acwengisisiwe. |
| Uhlelo Lokuhlanganisa | Hlanganisa amafutha ahlukene ngokwezilinganiso ozifunayo. |
| I-Hydrogenation Reactor | Iguqula amafutha aketshezi abe amafutha aqinile kancane (uma kudingeka). |
| Isixubi Esinoboya Obuningi | Ihlanganisa ama-emulsifiers kanye nezithasiselo ngokufanayo. |
| Isishintshi Sokushisa Esingaphezulu Esikhuhliwe (SSHE) | Ukupholisa okusheshayo kanye nokwakheka kwekristalu. |
| Amathangi Okwenza Ikristale | Ivumela ukwakheka kwamakristalu amafutha ngendlela efanele. |
| Uhlelo Lokuphampa Nokubhoboza | Idlulisela umkhiqizo phakathi kwezigaba. |
| Umshini Wokupakisha | Igcwalisa futhi ivale izitsha (amabhavu, izigubhu, noma izikhwama ezinkulu). |
3. Izinhlobo Zokufushanisa Imifino
- Ukufinyezwa Kwenhloso Yonke– Yokubhaka, ukuthosa, kanye nokupheka okuvamile.
- Ukufinyezwa Kokuzinza Okuphezulu– Yemikhiqizo yokuthosa kakhulu kanye neyokuhlala isikhathi eside.
- Ukufinyezwa Okungenayo i-Hydrogenated– Ayinawo amafutha adluliselwa ngokushintshashintshayo, kusetshenziswa ukuhlukaniswa kwesithakazelo noma ukuhlukaniswa.
- Ukufinyezwa Okuhlanganisiwe– Iqukethe ama-emulsifier engeziwe amakhekhe nama-icing.
4. Ukulawulwa Kwekhwalithi kanye Nezindinganiso
- I-Melting Point kanye ne-Solid Fat Index (SFI)– Kuqinisekisa ukuthungwa okufanele.
- Inani le-Peroxide (PV)- Kukala amazinga okuxinana kwe-oxidation.
- Okuqukethwe Kwamahhala Kwe-Acid Yamafutha (i-FFA)– Kubonisa ikhwalithi kawoyela.
- Ukuphepha Kwezinto Eziphilayo– Kuqinisekisa ukulandelwa kwemithethonqubo yokuphepha kokudla (FDA, EU, njll.).
5. Izicelo
- Imikhiqizo Yebhikawozi(amakhekhe, amakhukhi, amakhekhe)
- Ukuthosa Okuphakathi(ukudla okulula, ukudla okusheshayo)
- Indawo Yokudlela Amaswidi(izingubo zokugcoba ngoshokoledi, ukugcwalisa)
- Ezinye Izindlela Zobisi(abakhilimu bobisi abangebona abobisi)
Isiphetho
Umugqa wokukhiqiza imifino emfushane udinga ukulawula okunembile kokuxuba, ukwakheka kwekristalu, kanye nokupakishwa ukuqinisekisa umkhiqizo osezingeni eliphezulu. Imigqa yesimanje igxile kakhuluokungenayo i-hydrogenated, okungenawo amafutha e-transizixazululo ngenkathi kugcinwa ukusebenza kwezinhlelo ezahlukene zokudla.
