Njira ya Margarine

Kupanga margarine kumaphatikizapo njira zingapo zopangira chinthu chofalikira komanso chokhazikika chomwe chimafanana ndi batala koma chimapangidwa kuchokera kumafuta amasamba kapena kuphatikiza mafuta amasamba ndi mafuta anyama. Makina akuluakulu amaphatikiza thanki ya emulsification, voti, chosinthira kutentha kwapamtunda, makina a pini rotor, pampu yothamanga kwambiri, pasteurizer, chubu chopumira, makina onyamula ndi zina.

Nayi chithunzithunzi chazomwe zimachitika popanga margarine:

Kusakaniza Mafuta (kusakaniza thanki): Mitundu yosiyanasiyana ya mafuta a masamba (monga kanjedza, soya, canola, kapena mafuta a mpendadzuwa) amaphatikizidwa pamodzi kuti akwaniritse mafuta omwe amafunidwa. Kusankhidwa kwa mafuta kumakhudza mawonekedwe omaliza, kukoma, ndi thanzi la margarine.

Hydrogenation: Pa sitepe iyi, mafuta osatha m'mafuta amakhala ndi hydrogenated pang'ono kapena mokwanira kuti asandutse mafuta olimba kwambiri. Hydrogenation imawonjezera kusungunuka kwamafuta ndikuwongolera kukhazikika kwa chinthu chomaliza. Njirayi ingapangitsenso kupanga mafuta a trans, omwe amatha kuchepetsedwa kapena kuthetsedwa pogwiritsa ntchito njira zamakono zamakono.

Emulsification (emulsification tank): Mafuta osakanikirana ndi a hydrogenated amasakanizidwa ndi madzi, emulsifiers, ndi zina zowonjezera. Ma emulsifiers amathandizira kukhazikika kwa chisakanizocho poletsa mafuta ndi madzi kulekana. Ma emulsifiers wamba amaphatikiza lecithin, mono- ndi diglycerides, ndi ma polysorbates.

Pasteurization (pasteurizer): Emulsion imatenthedwa ndi kutentha kwina kuti iwononge, kupha mabakiteriya aliwonse oyipa ndikukulitsa moyo wa alumali wa mankhwalawa.

Kuziziritsa ndi Crystallization (Votator kapena scraped pamwamba kutentha exchager): The pasteurized emulsion utakhazikika ndi kuloledwa crystalline. Izi zimakhudza kapangidwe ka margarine ndi kusasinthika kwake. Kuzizira koyendetsedwa ndi crystallization kumathandizira kupanga chomaliza chosalala komanso chofalikira.

Kuonjezera Kukoma ndi Mtundu: Zokometsera zachilengedwe kapena zopangira, mitundu, ndi mchere zimawonjezeredwa ku emulsion yoziziritsa kuti iwonjezere kukoma ndi maonekedwe a margarine.

Kupaka: Margarine amaponyedwa m'mitsuko monga machubu kapena ndodo, kutengera zomwe wogula akufuna. Zotengerazo zimasindikizidwa kuti zisaipitsidwe komanso kuti zikhale zatsopano.

Kuwongolera Ubwino: Panthawi yonse yopangira, kuwunika kwaubwino kumachitidwa kuti margarine akwaniritse kukoma, kapangidwe, ndi chitetezo chomwe akufuna. Izi zikuphatikiza kuyesa kusasinthasintha, kukoma, mtundu, ndi chitetezo cha tizilombo.

Njira zamakono zopangira margarine nthawi zambiri zimayang'ana kwambiri kuchepetsa kugwiritsa ntchito hydrogenation ndikuchepetsa mafuta a trans. Opanga angagwiritse ntchito njira zina, monga zokondweretsa, zomwe zimasinthanso mafuta acids mumafuta kuti akwaniritse zomwe akufuna popanda kupanga mafuta osinthika.

Ndikofunika kuzindikira kuti ndondomeko yeniyeniyo imatha kusiyana pakati pa opanga ndi zigawo, ndipo zatsopano zaukadaulo wazakudya zikupitilizabe kukhudza momwe margarine amapangidwira. Kuphatikiza apo, kufunikira kwa zinthu zathanzi komanso zokhazikika kwadzetsa kupanga ma margarine okhala ndi mafuta ochepa komanso otsika, komanso omwe amapangidwa kuchokera kuzinthu zopangira mbewu.
