Dambudziko rekusachinja firita repeturu kwenguva yakareba nderei?
Mafuta emafuta achasanganiswa nezvimwe zvinhu zvisina kuchena panguva yekugadzira, kutakurwa uye kuwedzerwa mafuta. Kusachena mumafuta kuchavhara muromo wekuisa mafuta, uye tsvina ichanamirwa pamadziro ekupinda, sirinda nezvimwe zvikamu, zvichikonzera kuiswa kwekabhoni, zvichikonzera mamiriro asina kunaka ekushanda kweinjini. Chinhu chinosefa mafuta chinoshandiswa kusefa tsvina mumafuta, uye chinofanira kutsiviwa mushure menguva yekushandiswa kuti chive nechokwadi chekuti mafuta anoshandiswa zviri nani. Mhando dzakasiyana dzekuchinja mafirita emafuta emotokari dzichasiyanawo zvishoma. Kazhinji, firita yekunze yemhepo inogona kutsiviwa kana mota ichifamba makiromita angangoita zviuru makumi maviri nguva dzese. Firita yemhepo yakavakirwa mukati inowanzotsiviwa kamwe chete pamakiromita zviuru makumi mana.
