M'mayiko ndi zigawo zina nsomba zosaphika zimakhala zazikulu, zomwe zimabweretsa mavuto, monga ⑴. Pangani mayendedwe kukhala ovuta komanso kudya kosagwirizana. ⑵. Chepetsani Kuphika bwino komwe sikungatsimikizire kuti nsomba yaiwisi yophikidwa, ndipo mphamvu ya Cooker imachepetsedwa.
Pofuna kupewa vuto pamwamba, tikhoza kukhazikitsa ndiWophwanyakudula nsomba zazitali kuposa 20cm kukhala tizidutswa tating'ono ting'ono, kuti titsimikize kuti yunifolomu ndi kudyetsa mofanana.
Chophwanyiracho chimapangidwa ndi rotor yokhala ndi masamba okhazikika nthawi zonse komanso chimango chokhala ndi masamba osakhazikika. Rotor imayendetsedwa mwachindunji ndi mota kudzera pagulu kuti izungulira. Pamene nsomba yaiwisi yokhala ndi mawonekedwe akuluakulu imalowa kuchokera kumalo olowera, nsombayo imadulidwa kukhala yunifolomu yaying'ono komanso zidutswa zomwe zimadulidwa pakati pa masamba osuntha pa rotor ndi masamba okhazikika pa chimango chokhazikika, ndikutulutsidwa mosalekeza kuchokera kumtunda.
