1. Imashini y’ifi y’ifi izimye ikorwa mu gufatanya ingaruka z’amazi, umuvuduko, ubushuhe n’ugukemura kw’ubuhinga. Mu gihe co gukira, ubushuhe buri mu mashini burashobora gushika kuri 90 ~ 200%, kandi igihe co gusohoka kiri hagati y’amasegonda 2 ~ 30. Ico kintu gisohotse kirahinduka urutonde rw’ihinduka ry’umubiri n’iry’imiti, nk’uguhindura gelatinization y’imitsi, ukwaguka kwa poroteyine, enzymes, ibihimba vy’ubumara n’ukudakora kw’imigera. Gutegura ibifungurwa vy’amafi vy’umukara bisaba gutera umuriro n’amazi, kandi ibikoresho vyavyo bikwiye kuba birimwo n’imiburiburi 20% vy’imiti, ivyo bikaba ahanini bifise uruhara rw’ibintu bifatanya n’inguvu. Ubushuhe bw’ico kintu cakuwemwo bukwiye kuba 125 gushika kuri 138 imbere y’uko usohoka iyo mpeta pfa, ikirere 34 gushika kuri 37 (33 gushika ku 36 kg / cm2), 25 gushika kuri 27% vy’ubukonje; inyuma yo gusohoka, uburemere bw’ibintu vyinshi bukwiye kuba 320 gushika kuri 400 g / L, n’ubukonje 21 ~ 24. Iyo igisasu gitakaje 3 gushika ku 4 kw’ijana c’amazi iyo kivuye mu gitereko, umukazo urarekurwa bukwi na bukwi mu gihe igitero gisohoka kivuye mu gipfukisho, kugira ngo amazi ashushe ahinduke umuyagankuba maze ubukonje bw’ico kinyabiziga bukaba bugabanutse. Ivyuma vyinshi bitobito biraterwa kugira ngo bigabanye uburemere. Guhindura ibifungurwa kugira ngo ureremba. Kunywa ifi zigaburira kure cane (kenshi na kenshi munsi ya 10% y’ubukonje) birashobora kandi gutuma ubushobozi bwo kureremba butera imbere. Uburemere bwinshi bwa 480g / L bubonwa ko ari bwo buhinduka bw’uguterera ibifungurwa vy’ibitoke. Iyo uburemere bw’ibintu vyinshi buri hasi y’ivyo, ruzoreremba, kandi iyo ruri hejuru y’ubu buremere bw’ibintu vyinshi, ruzorohama.
2. Ubwoko n'Imirongo y'Imashini yo gutunganya amafi
Hari ubwoko bwinshi bw’ibisohoka kw’isoko. Mu bisanzwe, zishobora guca mu bice vy’inyuma vy’ibarabara rimwe n’ivy’amahasa y’amahasa. Igikoresho kimwe co gukuraho ivyuma bishobora guca mu bice vy’umubiri bishobora gukira, gukira kwumye n’ugusohoka kw’ibihimba vy’umubiri bikonje. Ico gikoresho muri rusangi gifise ibice bine, harimwo n’uburyo bwo kugaburira, igikoresho co guhindura ibintu, igikoresho co gukata n’ico gukata c’ivyo bikoresho. Igikoresho co kugaburira mu buryo buhinduka mu buryo bwo kugaburira ibikoresho vya mbere mu gitereko c’imbere. Uwukoresha arashobora gukurikirana no gukurikirana uko ivyo bifungurwa vyifashe biciye ku bimenyetso vy’urugero rwo hejuru n’ivyo hasi n’amadirisho y’ibirahuri. Ico gikoresho cuzuye amazi n’ubushuhe mu buryo bw’umwotsi. Ivyo vyose bihindura 40-50%. Extruder irambiranye harimwo umutwe n’umugozi. Igikorwa c’ivyo bikoresho ni uguteza imbere ibikoresho no kugenzura uburyo bwo gukiza mu musozo. Igipfukisho kiri mu gice c’ibifungurwa kiratera imbere ivyo bintu, kenshi na kenshi igikapu kiraba kiri kure cane; igice co hagati kirazingirako ibintu n’ibipfukisho; igice ca nyuma kirazimya buhoro buhoro, kugira ngo ivyo bintu bibe bibumbabumbwe mu gicuruzwa ca nyuma.
