Kukohwa kwemafuta kunoreva huwandu hwemafuta anotorwa kubva kune yega yega chirimwa chemafuta (seye rapeseed, soya bean, nezvimwewo) panguva yekubvisa mafuta. Kuburitswa kwemafuta ezvirimwa zveoiri kunotemwa neanotevera zvinhu:
1. Raw materials. Hunhu hwezvishandiso ndiyo kiyi yekuona goho remafuta (kuzara, huwandu hwetsvina, dzakasiyana, hunyoro, nezvimwewo)
2. Midziyo. Ndeipi midziyo inosarudzwa kune zvipi zvemafuta? Izvi zvakakosha zvikuru. Teerera pane anotevera mapoinzi matatu paunosarudza oiri yekutsikisa michina:
a. Kumanikidza kwekushanda kwemuchina: iyo yakakwira kudzvanywa kwekushanda, iyo yakakwirira mwero wemafuta;
b. Iyo slag content: iyo yakaderera iyo slag content, iyo yakakwirira yemafuta mwero;
c. Dry cake residual oil rate: iyo yakadzikira yasara mwero wemafuta, ndiyo inokwidza goho remafuta.
3. Kubvisa mafuta. Kune akasiyana mbizha zvigadzirwa, akasiyana ekutsikirira maitiro anofanirwa kusarudzwa:
a. Musiyano wemamiriro ekunze: Nzvimbo yezvakagadzirwa zvakasiyana, iyo oiri yekutsikirira maitiro akasiyana zvakare.
b. Zvigadzirwa zvakasiyana-siyana zvine maitiro akasiyana. Tora mhodzi yechibharo nenzungu semuenzaniso. Rapeseed chirimwa chemafuta chine medium-viscosity, medium-hard-shell uye medium-oil-rate, iyo inoburitsa kupikisa kukuru panguva yekutsikirira. Nzungu inonamira, yakapfava-goko, iri pakati nepakati-oiri-iri-mafuta, iyo inoburitsa diki diki panguva yekudzvanya. Naizvozvo, kana uchidzvanya mhodzi, tembiricha yemuchina wekutsikisa mafuta inofanirwa kudzikiswa, uye tembiricha nehunyoro hwemhodzi dzakasvibira dzinofanira kunge dzakaderera zvakare. Kazhinji, tembiricha yemuchina wekutsikisa mafuta embesa dzinofanirwa kunge inosvika 130 centi-degrees, tembiricha yembeu dzakasvibira dzinofanira kunge dziri 130 centi-degrees uye hunyoro hwemhodzi dzakasvibira dzinofanira kunge dziri 1.5-2.5%. Tembiricha yemuchina wekutsikisa mafuta enzungu inofanira kusetwa yakatenderedza 140-160 madhigirii, tembiricha yenzungu mbishi inofanira kunge iri pakati pe140-160 centi-degrees, uye hunyoro hunofanira kunge huri 2.5-3.5%.
