Ngokubanzi, iseti epheleleyo yesityalo sokusila irayisi sidibanisa ukucocwa kwerayisi, ukususwa kothuli kunye nokususa amatye, ukuguba nokupolisha, ukuhlela nokuhlelwa, umlinganiselo kunye nokupakishwa, njl. Imarike yaseAfrika, ukutsho imveliso yemihla ngemihla njengeetoni ezingama-20-30, iitoni ezingama-30-40, iitoni ezingama-40-50, iitoni ezingama-50-60, ezingama-80. ton, 100 ton, 120ton, 150 ton, 200 ton and etc. Ifom yofakelo yale line processing irayisi ibandakanya ufakelo tyaba (enye umaleko) kunye nofakelo inqaba (multi- umaleko).
Uninzi lwerayisi kwimarike yaseAfrika iphuma ekulinyweni komlimi ngamnye. Udidi luntsonkothile, iimeko zokomisa zimbi xa kuvunwa, nto leyo izisa ubunzima obukhulu ekulungiseni irayisi. Ekuphenduleni le nto, ukuyila inkqubo yokucoca i-paddy kufuna ukucocwa kwee-channel ezininzi kunye nokususwa kwamatye, kunye nokuqinisa i-winnowing ukuqinisekisa umgangatho we-paddy ecocekileyo. Ayinakuthembela kuphela kwisilungisi sombala sokuhlenga-hlengisa kwinqanaba lemveliso egqityiweyo. Ngokukhetha izixhobo zokucoca ezifanelekileyo, iinqununu zobukhulu obuhlukeneyo zihlelwa ngexesha lokucoca, kwaye emva koko zihlulwe kwi-shelling kunye nokunyanga okumhlophe, ukunciphisa irayisi ephukile kunye nokuphucula ixabiso lempahla yerayisi egqityiweyo.
Ukongeza, ukuba irayisi emdaka emva kokuba i-husking ibuyiselwe kwi-huller ukuze iqhube, kulula ukuphulwa. Kuyacetyiswa ukuba ungeze isahluli se-paddy phakathi kwe-husker kunye ne-rice polisher, ekwazi ukwahlula irayisi emdaka kwi-rayisi engaxutywanga, kwaye uthumele irayisi engaxutywanga kwakhona kwi-husker ukuze i-husker, ngelixa irayisi emdaka eboshiweyo ingena kwi-husker. inyathelo elilandelayo lokwenza mhlophe. Ulungelelwaniso olunengqiqo kumandla okuqengqeleka kunye nokwahluka kwesantya somgca, akunciphisi nje kuphela ireyithi eyaphukileyo yerayisi, kodwa nokunciphisa ukusetyenziswa kwamandla, kulula ekusebenzeni nasekulawuleni.
Ubumanzi obufanelekileyo bokulungiswa kwerayisi yi-13.5% -15.0%. Ukuba ukufuma kuphantsi kakhulu, izinga lerayisi elaphukileyo ngexesha lenkqubo yemveliso liya kwanda. I-atomization yamanzi inokongezwa kwinqanaba lerayisi emdaka ukunyusa umlinganiso wokukhuhlana komphezulu werayisi omdaka, onceda ekusileni kunye nokupholiswa kwebran yerayisi, ukunciphisa uxinzelelo lokugaya irayisi kunye nokunciphisa izinga lerayisi elaphukileyo ngexesha lokusila, umphezulu werayisi ogqityiweyo. iya kuba yinto efanayo kwaye ibengezelelekileyo.
