Ngokuvamile, isethi ephelele yesitshalo sokugaya irayisi ihlanganisa ukuhlanzwa kwerayisi, ukususwa kothuli namatshe, ukugaya nokupholisha, ukugreda nokuhlunga, ukukala nokupakisha, njll. Kunamamodeli ahlukene esitshalo sokugaya irayisi esiphelele esinezinhlobo ezahlukene zokukhipha amandla okuthekelisa Imakethe yase-Afrika, ukusho ukukhiqizwa kwansuku zonke njengamathani angama-20-30, amathani angama-30-40, amathani angama-40-50, amathani angama-50-60, angama-80 ton, 100 ton, 120ton, 150 ton, 200 ton nokunye. Ifomu lokufakwa lale migqa yokucubungula irayisi ihlanganisa ukufakwa okuyisicaba (ungqimba olulodwa) nokufakwa kombhoshongo (izendlalelo eziningi).
Iningi lalayisi emakethe yase-Afrika livela ekutshalweni komlimi ngamunye. Izinhlobonhlobo ziyinkimbinkimbi, izimo zokomisa zimbi lapho kuvunwa, okuletha ubunzima obukhulu ekucutshungulweni kwerayisi. Ukuphendula lesi simo, ukuklanywa kwenqubo yokuhlanza i-paddy kudinga ukuhlanzwa kwamashaneli amaningi kanye nokususwa kwamatshe, futhi kuqinisa ukwela ukuze kuqinisekiswe ikhwalithi ye-paddy ehlanzekile. Ngeke ithembele kuphela kusihlungi sombala ukuze sihlele esigabeni somkhiqizo oqediwe. Ngokukhetha imishini yokuhlanza enengqondo, izinhlayiya zobukhulu obuhlukahlukene zihlungwa phakathi nenqubo yokuhlanza, bese zihlukaniswa ukugoqa kanye nokwelashwa okumhlophe, ukunciphisa irayisi ephukile nokuthuthukisa inani lempahla yerayisi eliphelile.
Ukwengeza, uma irayisi elinsundu ngemva kokukhipha ihusking libuyiselwa ku-huller ukuze ligoqeke, kulula ukuliphuka. Kunconywa ukuthi wengeze isihlukanisi se-paddy phakathi kwe-husker kanye ne-rice polisher, engahlukanisa irayisi elinsundu eligoqiwe nelayisi elingagoqiwe, bese uthumela irayisi elingagoqiwe emuva esikhumbeni ukuze likhishwe, kuyilapho irayisi elinsundu eligoqiwe liyangena. isinyathelo esilandelayo sokwenza mhlophe. Ukulungiswa okunengqondo kwamandla okugoqa kanye nomehluko wesivinini esiqondile, akugcini nje ukunciphisa izinga lelayisi eliphukile, kodwa futhi kunciphisa ukusetshenziswa kwamandla, okulula ekusebenzeni nasekuphatheni.
Umswakama ofanelekile wokucubungula irayisi ngu-13.5% -15.0%. Uma umswakama uphansi kakhulu, izinga lerayisi eliphukile phakathi nenqubo yokukhiqiza lizokhula. I-atomization yamanzi ingengezwa esigabeni serayisi elinsundu ukuze kwandiswe i-coefficient ye-friction ye-brown rice surface, evumela ukugaywa nokupholishwa kwe-rice bran, ukunciphisa ingcindezi yokugaya irayisi futhi kwehlise izinga lerayisi eliphukile ngesikhathi sokugaya, ingaphezulu lelayisi eliqediwe. izoba iyunifomu futhi icwebezele.
