Mu kiseera kino, ebyuma ebisinga okuliisa emmere mu nsi yaffe bikozesa obuwunga obulimu empeta okukola emmere y’omu mazzi. Ebikuta ebikalu ebiva mu kuzimba obukuta obulimu empeta wansi okumala eddakiika 10-20 n’oluvannyuma ne bisasika, nga tebirina kye biyinza kuliisa, ate ebimu bisigala mu mbeera y’amazzi, ekiyonoona nnyo omutindo gw’amazzi; Wadde nga emmere efulumiziddwa efuna ebbugumu eringi ne puleesa enkulu, kika kya bucaafu obutono , emmere ekuuma obutonde bw’ensi nga kasasiro mutono ate ng’akyusa nnyo. N’olwekyo, ebintu ebifulumizibwa mu mazzi bikyusizza mpolampola obukuta obukalu ne bufuuka emmere enkulu ey’emmere y’omu mazzi. Enkola y’okukola emmere efulumizibwa mu mazzi okutwalira awamu erimu ebigimusa okumenyaamenya, okutabula, okufulumya micronization ey’okubiri, okufulumya, okukala, okunyogoza n’enkola endala. Mu byo, okufulumya kulina ekifo ekikulu ennyo mu nkola yonna era kikola kinene ku mutindo gw’emmere n’obulungi bw’okufulumya. Obunene. Olw’ensonga eno, ekiwandiiko kino kyogera ku mpisa z’emirimu n’okulonda okutuufu okw’ebifulumya eby’omu mazzi eby’omu mazzi ebimu n’ebibiri ebifulumya emmere ey’omu mazzi, era kiwa ebijuliziddwa eri abakola ebyuma ebikozesebwa mu kufulumya emmere ey’omu mazzi mu ngeri entuufu, tekinologiya ow’okufulumya asobole ddala okuzannya ekifo mu kukola. Okutuukiriza ekigendererwa eky’okwongera ku kukola, okukendeeza ku nkozesa, n’okulongoosa mu kugaaya ebiriisa n’okukozesa amaanyi mu kiseera ky’okuliisa.
The twin-screw extruder erina ebirungi eby’okukyusakyusa ennyo, okutambuza okusereba n’okweyonja, naye ensengeka yaayo nzibu, ssente z’okuteeka ssente nnyingi nnyo, era n’ebisale by’okuddaabiriza n’okukola ebikwatagana nabyo biri waggulu. N’olwekyo, okutwalira awamu ekyuma ekiyitibwa twin-screw extruder kikozesebwa mu kukola ebintu eby’omu mazzi eby’omuwendo omungi n’emmere y’ebisolo by’omu nnyumba, gamba ng’okukola emmere ey’ekika kya eel, turtle ne juvenile feed, kubanga ebbeeyi y’ebintu bino ku katale emala okusasula tekinologiya wa twin-screw. ssente ezisaasaanyizibwa mu kukola ebintu; Ebirungo ebirala eby’enjawulo eby’omu mazzi, gamba ng’emmere ennungi ey’omu mazzi (0.8-1.5mm mu buwanvu), emmere y’omu mazzi erimu amasavu amangi, n’emmere erimu obuzito obutono naye emirundi mingi ekyukakyuka mu nkola zetaaga okukolebwa n’ebifulumya ebibiri ebibiri.
Enkulaakulana ya twin-screw extruder ekeeredde nnyo mu China. Ku kifulumya eky’obunene obwa wakati, olw’engeri nnyingi ez’ebintu ebisookerwako, sipiidi ya sikulaapu yeetaaga okutereezebwa mu bbanga eddene, kubanga enkola yaayo ey’okukola ya njawulo ku ya sinema emu efulumya sikulaapu erina enjawulo nnene mu nsengeka eyeetongodde naddala enteekateeka y’ebipipa, sikulaapu, thrust bbeeri ne ggiya bizibu nnyo, ekivaako okweyongera kw’omuwendo gw’ensimbi z’ebyuma.
