Izinto ezithwala uwoyela ezinamagobolondo anjengamantongomane, imbewu kabhekilanga, imbewu kakotini, nezimbewu zetiye, kufanele zidluliselwe kumshini wokukhipha uwoyela ukuze kukhishwe igobolondo futhi kuhlukaniswe namakhoba angaphandle ngaphambi kwenqubo yokukhipha uwoyela, amagobolondo nezikhwebu kufanele zicindezelwe ngokwehlukana. .Ama-Hulls azonciphisa isamba sesivuno sikawoyela ngokumunca noma ngokugcina uwoyela kumakhekhe kawoyela acindezelwe.Ngaphezu kwalokho, i-wax nenhlanganisela yemibala ekhona esikhumbeni igcina emafutheni akhishiwe, angafuneki emafutheni adliwayo futhi adinga ukususwa ngesikhathi sokucwengwa.I-Dehulling ingabizwa nangokuthi i-shelling noma ukuhlobisa.Inqubo ye-dehulling iyadingeka futhi inezinzuzo zochungechunge, yandisa ukusebenza kahle kokukhiqizwa kukawoyela, umthamo wemishini yokukhipha futhi inciphisa ukuguga komxosha, inciphisa i-fiber futhi ikhulise okuqukethwe kwamaprotheni ekudleni.
