Nyuma yo gusembura, icyayi cyirabura gikenera aIcyayi cyumye. Fermentation nicyiciro cyihariye cyo gutanga icyayi cyirabura. Nyuma yo gusembura, ibara ryamababi rihinduka kuva icyatsi kibisi gitukura, bikora ubuziranenge bwicyayi cyirabura, amababi atukura nisupu itukura. Nyuma yo gusembura, icyayi cyirabura kigomba gukama vuba cyangwa cyumye. Bitabaye ibyo, niba irundanyije igihe kirekire, izabyara impumuro mbi. Uburyo bwo kumisha bugabanijwemo ibyiciro bibiri: kubanza gukama hamwe numuriro ukabije no gutukura hamwe numuriro wuzuye.

Kuma icyayi cy'umukara ni inzira aho icyayi gisembuye gitetse ku bushyuhe bwo hejuru kugira ngo amazi ahumuke vuba kandi agere ku cyuma kibungabunga ubuziranenge. Intego yacyo ni eshatu: gukoresha ubushyuhe bwo hejuru kugirango uhite ukora ibikorwa bya enzyme no guhagarika fermentation; guhumeka amazi, kugabanya amajwi, gutunganya imiterere, no gukomeza gukama kugirango wirinde indwara; gusohora ibyinshi mubyatsi bito-bitetse ibyatsi bihumura, kongera imbaraga no kugumana ingingo zitetse cyane ibintu bihumura neza, no kubona impumuro nziza idasanzwe yicyayi cyirabura.

Mugihe ukora icyayi cy'umukara, banza uhitemo amababi n'amababi akwiranye ukurikije umusaruro w'icyayi cy'umukara, hanyuma wumishe amababi mashya kugeza yumye. Ibi bituma amababi mashya ahumeka amazi uko bikwiye kugirango yongere ubukana kandi yorohereze imiterere. Noneho amababi yicyayi ashyirwa muri aImashini yicyayikuri 200 ° C hanyuma ukaranze-ukaranze kugirango wangize selile yamababi hanyuma usohore umutobe wicyayi, bigatuma amababi yicyayi akora imigozi igororotse kandi byongera ubwinshi bwisupu yicyayi. Amababi yicyayi ashyirwa muburyo budasanzweImashini yicyayicyangwa icyumba cya fermentation kugirango ferment, kugirango amababi yicyayi akureho ibiranga amababi atukura nisupu itukura.

Intambwe yanyuma iruma. Koresha aImashini yumisha icyayigukama kabiri. Igihe cya mbere ni umuriro ukabije, naho ubwa kabiri ni umuriro wuzuye. Ibi bituma icyayi cy'umukara gihumeka amazi, gukaza inkoni z'icyayi, gutunganya imiterere, kugumya gukama, no gukwirakwiza icyayi cy'umukara. Icyatsi kibisi ku cyayi kigumana impumuro nziza yicyayi cyirabura.
