Zipangizo zopangira Chitsulo Chotentha kapena Chozizira zitha kupangidwa ndi njira iliyonse.
Chitsulo Chotenthedwa: Pakupanga, chitsulo chotenthedwa ndi moto chimatenthedwa poyamba kutentha kwambiri, zomwe zimapangitsa kuti chitsulocho chizunguliridwe ngati pulasitiki, zomwe zimapangitsa kuti zikhale zosavuta kusintha mawonekedwe ndi kukula kwa chitsulocho. Pamapeto pa ndondomeko yotenthedwa, zinthuzo nthawi zambiri zimadulidwa ndikuwonongeka.
Chitsulo Chozizira Chozungulira: Chitsulo chozizira chimakulungidwa kwambiri zinthuzo zitazizira kuti zifike pa kukula ndi mawonekedwe omwe mukufuna. Njirayi nthawi zambiri imachitika kutentha kwa chipinda ndipo imapangitsa kuti chitsulo chikhale ndi mawonekedwe abwino komanso kukula kolondola.
