Amathangi Ensimbu Okugcina Amafutha Esundu: Ubunjiniyela, Ukufudumeza Nokugcina Ikhwalithi
Ithangi lensimbi lokugcina amafutha esundu liyisitsha esikhethekile esisindayo sezimboni sokugcina uketshezi, esakhelwe ukugcina i-Crude Palm Oil (CPO), i-RBD palm oil, i-palm olein, ne-palm stearin ngaphansi kwezilawuli eziqinile zokushisa nomoya.
Lisebenza ezimbonini zamafutha esundu, ezindaweni zokucwenga, nasezikhumulweni zasolwandle zokuthumela ngobuningi, lawa mathangi ensimbi amile aqondile avimbela amafutha esundu ukuba aqine emazingeni okushisa avamile, ngenkathi evikela uketshezi ekushisweni okushisayo, ukugqwala, kanye nokubola okubangelwa umswakama.
Izidingo Ezibalulekile Zobunjiniyela Zokugcina Amafutha Esundu
I-oli ye-palm inezici ezikhethekile zomzimba: ihlala iwuketshezi ngaphezu kuka-35C - 40C, kodwa iyacwebezela futhi iqine ibe wuketshezi olusindayo emazingeni okushisa aphansi. Ukugcina izinkulungwane zamathani wemethrikhi kudinga izinhlelo eziyimishini ezikhethekile:
1. Izinhlelo Zokuphatha Ukushisa Nokufudumeza
Ukuze i-oli ye-palm ihlale iphampuphu ngaphandle kokulimaza ukwakheka kwayo kwamakhemikhali, amathangi okugcina afakwa izinhlelo zokufudumeza zangaphakathi:
● Amakhoyili Esitimu Nezifunda Zamanzi Ashisayo: Amakhoyili okufudumeza ensimbi engagqwali abekwe phansi ethangini agcina izinga lokushisa le-oli elingaguquki lika-50°C - 55°C le-Crude Palm Oil (CPO) kanye no-60°C - 65°C we-palm stearin encibilika kakhulu.
● Ukufudumeza Okunamandla Aphansi: Kuvimbela ukushisa ngokweqile endaweni ethile. Amazinga okushisa aphezulu angaphezu kuka-70°C ayishisa i-oli, ayenze ibe mnyama futhi asheshise ukuhlangana kwayo nomoya-mpilo.
● Ukugqwayiza Ukushisa Kwangaphandle: Kuhlanganiswe ne-rockwool noma i-polyurethane foam enezingubo ze-aluminium ukuze kugcinwe ukushisa futhi kuncishiswe ukusetshenziswa kukaphethiloli ebhayilerini.
2. Ukulawulwa Kwe-Oxidation & Ikhwalithi
Ukuveza uwoyela ophekiwe ofudumele emoyeni kubangela ukugcwala komoya okusheshayo, kwenyusa i-Peroxide Value (PV) futhi konakalise ukunambitheka:
● Ukumboza ngeNitrogen: Kususa umoya-mpilo ongaphakathi kwesikhala esingenalutho ngesembozo se-nitrogen engenzi lutho.
● Ukugcwalisa nge-Bottom-Inlet: Ukupompa uwoyela ngeminyango engaphansi ecwiliswayo kugwema ukuchithakala nokungena komoya ngesikhathi sokugcwalisa ithangi.
Izinhlobo Zamathangi Ensimbili Asetshenziselwa Ukugcina Uwoyela Wesundu
Ukukhetha ingxubevange yensimbi efanele kanye nendlela yokwakha kuncike ekutheni ithangi lihlala kuphi ochungechungeni lokuhlinzeka:
1. Amathangi Ensimbili ye-Carbon ane-Food-Grade Epoxy Linings
Ukukhetha okujwayelekile kokugcina i-Crude Palm Oil (CPO) emazingeni amakhulu ezimboni nasezikhumulweni zemikhumbi ezinkulu (1,000 m3 kuya ku-20,000+ m3). Insimbi ye-carbon inamandla amakhulu esakhiwo ngezindleko eziphansi zokwakha. Ingaphakathi limbozwa nge-resin ekhethekile ye-epoxy engangenwa ukushisa, esezingeni lokudla, ukuvimbela ukungcoliswa yinsimbi, okwenza kube yimbangela yokugqwala.
2. Amathangi Ensimbi Engagqwali (AISI 304 / 316L)
Izinga legolide lamafutha okupheka acwengisiwe, ane-purity ephezulu njenge-RBD Palm Olein, amafutha okupheka, namafutha akhethekile. Insimbi engagqwali inikeza ukungasebenzi kwamakhemikhali okuphelele, ukungabi nokuchithwa kwe-iron, ukuhlanza okulula kwe-CIP (Clean-In-Place), kanye nempilo yokuklama engaphezu kweminyaka engu-30-50.
3. Amathangi e-Glass-Fused-to-Steel (GFS) / Amathangi Ensimbu Abhontshiwe
Amaphaneli abhontshiwe enziwe efemini afakwe uglasi ohlanganisiwe. Amathangi e-GFS aqeda ukushisela endaweni, asheshisa ukufakwa ezindaweni ezikude zezitshalo zasemahlathini, futhi anikeza ukumelana nokugqwala okuphezulu emanzini amuncu e-palm oil mill effluent (POME) kanye nokugeleza kukawoyela ongahluziwe.

Imibuzo Evame Ukubuzwa (FAQ)
Q1: Iyiphi izinga lokushisa elifanele lokugcina i-Crude Palm Oil (CPO)?
Impendulo: I-Crude Palm Oil kufanele igcinwe ezingeni lokushisa elizinzile phakathi kuka-50C no-55C (122F - 131F). Ukugcina ngaphansi kuka-40C kuholela ekwakhekeni kwamakristalu nokuhlukaniswa, kuyilapho ukushisisa ngaphezu kuka-60C isikhathi eside kwenyusa amazinga e-Free Fatty Acid (FFA) futhi kubangele ukonakala ngenxa yokushisa.
Q2: Kungani i-copper noma i-brass inqatshelwe emathangeni okugcina uwoyela wesundu?
Impendulo: I-Copper, i-brass, ne-bronze zisebenza njengezinto ezinamandla ezikhuthaza ukugqwala kwamafutha, okusheshisa ukonakala kukawoyela wesundu ngisho noma kunamazinga aphansi (<0.05 ppm). Zonke izingxenye zangaphakathi zethangi, ama-valve, amaphampu, nezintambo zokushisisa kufanele zenziwe ngensimbi engagqwali noma ngezinto ezingezona ezensimbi ezigunyaziwe.
Q3: Izintambo zokushisisa zivimbela kanjani uwoyela wesundu ukuthi ungashisi ngaphakathi ethangini?
Impendulo: Izintambo zokushisisa zisebenzisa umhwamuko onomfutho ophansi noma amanzi ashisayo adlula emapayipini ensimbi engagqwali anendawo enkulu. Ngokugcina amazinga okushisa esikhumbeni sezintambo ephansi (ngokuvamile ngaphansi kuka-105°C), uwoyela ushiswa kancane ngokuhamba komoya ngaphandle kokushiswa noma ukuguquka kombala endaweni ethile.
Umbuzo 4: Kungani kusetshenziswa i-nitrogen blanketing emathangini kawoyela wesundu?
Impendulo: I-nitrogen blanketing ingena esikhundleni somoya-mpilo osemoyeni osendaweni engaphezulu yethangi ngegesi ye-nitrogen engasebenzi. Lokhu kuvimbela ukuthintana komoya-mpilo nendawo ewuketshezi eshisayo, kumisa ukugqwala, kulondoloze umbala, futhi kunciphisa ukunqwabelana kwama-Free Fatty Acids (FFA).
