Izinto ezithwala ioyile ezinamaqokobhe anje ngamandongomane, imbewu kajongilanga, imbewu yomqhaphu, kunye ne teaseeds, kufuneka zidluliselwe kwi-seed dehuller ukuze ikhutshelwe kwaye yahlulwe kwi-husk yabo yangaphandle ngaphambi kwenkqubo yokukhutshwa kwe-oyile, amaqokobhe kunye neenkozo kufuneka zicinezelwe ngokwahlukileyo. .IiHulls ziya kunciphisa isivuno se-oyile sisonke ngokufunxa okanye ngokugcina i-oyile kwiikeyiki ze-oyile ezicinezelweyo.Ngaphezu koko, i-wax kunye neekhompawundi zombala ezikhoyo kwii-hulls ziphela kwi-oyile ekhutshiweyo, engathandekiyo kwiioli ezidliwayo kwaye kufuneka zisuswe ngexesha lokucoca.I-dehulling ingabizwa ngokuba yi-shelling okanye ukuhombisa.Inkqubo yokukhupha i-dehulling iyimfuneko kwaye ineenzuzo ezilandelelanayo, yonyusa ukusebenza kakuhle kwemveliso yeoli, umthamo wezixhobo zokukhutshwa kunye nokunciphisa ukunxiba kwi-expeller, inciphisa ifayibha kwaye inyusa umxholo weprotheyini yesidlo.
