Zoumitsidwa zimayikidwa pamalo okwera-amagetsi obwera pafupipafupi, ndipo kasinthasintha-pamalo amagetsi amatenthetsa chinthucho kuti chiwumitsidwe. Chodziwika kwambiri cha njira yotenthetsera iyi ndikuti madera omwe ali ndi chinyezi chambiri amalandira kutentha kwambiri. Chifukwa chakuti chinyezi chamkati mwazinthuzo ndi chapamwamba kuposa pamwamba pake, mphamvu zambiri zimapeza mkati mwazinthu, zomwe zimapangitsa kutentha kwapakati kuposa kutentha kwapamwamba. Izi zimagwirizanitsa kutentha kwa kutentha ndi komwe kumachokera ku chinyezi, kufulumizitsa vaporization ya madzi ndi kufupikitsa nthawi yowumitsa. Chowumitsa chamtunduwu chimakhala choyenera makamaka pazinthu zomwe zimapanga kutumphuka mosavuta panthawi yowuma kapena zipangizo zomwe chinyezi chamkati chimakhala chovuta kuchotsa kwathunthu (monga chikopa). Kuyanika kwa dielectric kumagwiritsa ntchito mphamvu zambiri zamagetsi ndipo kumagwiritsidwa ntchito makamaka popanga zakudya komanso kupanga mafakitale opepuka. Mapangidwe ndi kuwerengera kwa chowumitsira kuyenera kuyamba ndi kusankha chowumitsira choyenera.
Kusankhidwa kwa chowumitsira kumatengera zomwe zachitika, ndipo izi ziyenera kuganiziridwa:
① Makhalidwe azinthu ndi zinthu, monga mawonekedwe a zinthu (mwachitsanzo, slurry, phala, ufa, granules, flakes), kukula kwa tinthu ndi mphamvu ya tinthu tating'onoting'ono tolimba, chinyezi choyambirira ndi mawonekedwe a chinyezi, kaya ndi poizoni, choyaka, kapena oxidized mosavuta, chinyezi chofunikira chomaliza cha chinthucho, kaya ndi choipitsidwa ndi kusintha pang'ono, ngakhale kuipitsidwa pang'ono, kuipitsidwa kwapang'ono. zovomerezeka, kutentha kwakukulu kovomerezeka kwa chinthucho, ndi mtengo wake.
② Mikhalidwe yokhudzana ndi kapangidwe kake, monga kuchuluka kwa zinthu zomwe zidakonzedwa, zisanachitike- ndi-zikhalidwe zachipatala, zosungunulira zosasinthika, komanso ngati zikufunika kubwezeredwa.
③ Kugwira ntchito kwa chowumitsira ndi zizindikiro zachuma. Pambuyo poganizira mozama zomwe zili pamwambazi ndikuyerekeza ndikuwunika zowumitsa zosiyanasiyana, ndi mitundu yochepa chabe ya zowumitsa zomwe zimatsalira. Mayeso ang'onoang'ono-amachitidwa kuti apeze njira zoyendetsera ntchito ndi kamangidwe koyenera. Pomaliza, kutengera mtengo wa zida ndi zotsatira za mayeso ang'onoang'ono-, kusankha chowumitsira kumatsimikiziridwa.
