Kupanga mafuta a nsomba ndi ufa wa nsomba

Ufa wa nsomba ndi mafuta a nsomba amapangidwa pokonza zinthu monga kuphika, kukonza, kuchotsa, ndi kuyanika. Chokhacho chomwe chimapangidwa panthawi yopanga nsomba ndi mafuta a nsomba ndi nthunzi. M'malo mwake, mankhwalawa amapangidwa ndi zosakaniza zonse zosaphika, ngakhale zambiri zimakhala zonyowa. Pofuna kutsimikizira kuti zinthu zomaliza zimatsata miyezo yazakudya komanso zowononga, kukonza kumachitika motsatira njira zowongolera bwino. Zakudya zopatsa thanzi ziyenera kusungidwa momwe zingathere kuti njirayo isamutsire bwino mafuta a nsomba ndi mafuta a nsomba.

Makina okazinga mafuta a nsombaamapangira nsomba zatsopano pa kutentha kwa 85 ° C mpaka 90 ° C kuti agwirizane ndi mapuloteni ndikulekanitsa ena mwa mafuta. Tizilombo ting'onoting'ono timapangidwa nthawi imodzi kuti tisagwire ntchito ndi makinawa. Kusagwira ntchito kwa mabakiteriya kumatha kuonjezedwa ndikuwonongeka kupewedwa pogwiritsa ntchito zida zopatsirana zoyera ndi zosungirako, nthawi yayitali yosungirako, komanso kutentha kochepa. Kutentha kochepa kwambiri kumalepheretsanso kugwira ntchito kwa ma enzymes a nsomba, ndikuletsa kuwola mwanjira ina. Pambuyo pake, nsomba yophika imatumizidwa ku ascrew press, kumene madzi amachotsedwa ndipo nsombayo amaphwanyidwa kukhala makeke isanasunthidwe mu chowumitsira.

Pambuyo pofinyidwa, madziwo amadutsa mu decanter kuti achotse zolimba zotsalira, ndikutsatiridwa ndi centrifuge kuti alekanitse mafuta ndi kupanga madzi a nsomba zakuda. Pambuyo pake, madzi a nsomba amawunikidwa ndipo amasanduka nthunzi. Keke ya nsomba ndi madzi a nsomba wokhuthala amaziphatikiza mu chowumitsira. Ma coil amawoneka mkati mwa zowumitsira, pomwe nthunzi yotentha imayambitsidwa. Pofuna kusunga chinyezi cha keke yowuma ya nsomba ku 10% yokha, makolawa amatha kuwongolera kutentha mpaka 90 ° C (kutentha kwa nthunzi kumayendetsedwa ndi kayendedwe kake). Zowumitsira kutentha pang'ono zimagwira ntchito potentha kwambiri, mongazowumitsira nthunzi zosalunjika kapena zowumitsira vacuum.

Sefa yapadera idzagwiritsidwa ntchito kuchotsa zonyansa zosungunuka mafuta ku mafuta a nsomba pambuyo pa kuyeretsedwa ndi njira zina zolekanitsa zonyansa zolimba. Amapanga mafuta a nsomba owoneka bwino, opanda fungo opangira mankhwala kapena zakudya, monga makapisozi amafuta a nsomba, kutsatira njira zina zovuta kukonza.
