Mohala oa Tlhahiso ea Vegetable Shortening
Ho khutsufatsa meroho ke mafura a semi-solid a entsoeng ka oli ea meroho ka mekhoa e kang hydrogenation, blending, le crystallization. E sebelisoa haholo ho baka, ho halika le ho lokisa lijo ka lebaka la botsitso ba eona bo phahameng le boreleli ba eona. Mohala oa ho khutsufatsa meroho o kenyelletsa mehato e 'maloa ea bohlokoa ho netefatsa boleng, botsitso le polokeho ea lijo.
1. Mekhoa e ka Sehloohong ea ho Khutsufatsa Meroho
(1) Ho Lokisetsa Oli & Ho Kopanya
- Oli ea meroho e hloekisitsoeng:Oli ea motheo (soybean, palema, cottonseed, kapa canola) e hloekisoa ho tlosa litšila.
- Ho kopanya:Lioli tse fapaneng li tsoakoa ho fihlela sebopeho se lakatsehang, ntlha ea ho qhibiliha le botsitso.
(2) Hydrogenation (Ka boikhethelo)
- Karolo ea hydrogenation e ka sebelisoa ho eketsa botsitso le mafura a tiileng (le hoja bahlahisi ba bangata hona joale ba sebelisa mekhoa e seng ea hydrogenated ka lebaka la ho ameha ka mafura a trans).
- Catalyst & Hydrogen Gas:Oli e hloekisoa ka mochine oa nickel le khase ea hydrogen tlas'a mocheso o laoloang le khatello.
(3) Emulsification & Additives Mixing
- Li-emulsifiers (mohlala, lecithin, mono- le diglycerides) lia eketsoa bakeng sa ntlafatso ea sebopeho.
- Li-preservative, li-antioxidants (mohlala, TBHQ, BHA), le litlolo li ka kenyelletsoa.
(4) Ho pholisa le Crystallization (Ho futhumatsa)
- Motsoako oa oli o pholile ka potlako ho amochini o futhumatsang mocheso o qhibilihisitsoeng (SSHE)ho etsa dikristale tse tsitsitseng tsa mafura.
- Lijana tsa Crystallization:Sehlahisoa se tšoaroa tlas'a maemo a laoloang ho hlahisa ho lumellana ho nepahetseng.
(5) Sephutheloana
- Khutsufatso e tletselibate tsa polasetiki, linkho, kapa lijana tse ngata tsa indasteri.
- Ho ntša naetrojene ho ka sebelisoa ho lelefatsa nako ea bophelo.
2. Lisebelisoa tsa Bohlokoa Moleng oa Tlhahiso ea ho Khutsufatsa meroho
| Thepa | Mosebetsi |
| Litanka tsa polokelo ea oli | Boloka oli ea meroho e hloekisitsoeng. |
| Sistimi ea ho kopanya | Kopanya oli e fapaneng ho ea ho tse lakatsehang. |
| Hydrogenation Reactor | E fetolela oli ea metsi ho ba mafura a semi-solid (haeba ho hlokahala). |
| Motsoako oa High-Shear | E kenyelletsa li-emulsifiers le li-additives ka mokhoa o ts'oanang. |
| Scraped Surface Heat Exchanger (SSHE) | Pholiso e potlakileng & kristale. |
| Litanka tsa Crystallization | E lumella sebopeho se nepahetseng sa kristale ea mafura. |
| Sistimi ea Pump & Piping | E fetisetsa sehlahisoa pakeng tsa mekhahlelo. |
| Mochini oa ho paka | E tlatsa le ho koala lijana (lijana, meropa kapa mekotla e mengata). |
3. Mefuta ea ho khutsufatsa meroho
- Khutsufatso ea Morero Oohle- Bakeng sa ho baka, ho halika, le ho pheha ka kakaretso.
- Ho Khutsufatsoa ka Botsitso bo Phahameng- Bakeng sa ho halika ho tebileng le lihlahisoa tse telele tsa bophelo.
- Ho Khutsufatsoa ka Non-Hydrogenated- Ha e na mafura, e sebelisa thahasello kapa karohano.
- Emulsified Shortening- E na le li-emulsifiers tse ekelitsoeng bakeng sa likuku le li-icings.
4. Taolo ea Boleng & Maemo
- Melting Point & Solid Fat Index (SFI)- E netefatsa sebopeho se nepahetseng.
- Boleng ba Peroxide (PV)- E lekanya maemo a oxidation.
- Likahare tsa Mafura a Mafura a Mahala (FFA).- E bontša boleng ba oli.
- Tšireletso ea Microbiological- E netefatsa ho latela melao ea polokeho ea lijo (FDA, EU, joalo-joalo).
5. Likopo
- Lihlahisoa tsa Bakery(likuku, likuku, likuku)
- Ho Frying Medium(li-snacks, lijo tse potlakileng)
- Confectionery(liaparo tsa chokolete, ho tlatsa)
- Mefuta e meng ea lebese(li-cream tse seng tsa lebese)
Qetello
Mohala oa tlhahiso ea meroho o khutsufatsang o hloka taolo e nepahetseng holim'a ho kopanya, crystallization, le ho paka ho netefatsa sehlahisoa sa boleng bo holimo. Mela ea kajeno e lebisa tlhokomelo hoe senang haedrojene, e senang mafuratharollo ha u ntse u boloka ts'ebetso ea lisebelisoa tse fapaneng tsa lijo.
