Iyo uruganda rushasha rwo gutunganya ibifungurwa canke uruganda rwa kera rukoreshwa mu gusanura umurongo w’intango wo guhingura ibifungurwa, igihe uhitamwo igikoresho co gukoresha amahasa, banza uzirikane ubwoko bwaco n’ivyo isobanura, maze ukamenya ibikoresho bihuye hakurikijwe ubushobozi bwo gukora; cane cane iyo uruganda rwa kera rusubiye kwubaka, birakenewe kandi ko twiyumvira nimba ubushobozi bwo gukora bw’insyo y’intango, umumezi, n’umukozi wo gukonjesha bishobora gushigikira ibikorwa bisanzwe vy’imashini nshasha .
Ku bijanye no gutunganya ibifungurwa, ingaruka nziza yo kwagura y’ugusohoka kw’amahasa igira ingaruka zitaziguye ku rugero rw’imiterere y’igipande rurenga 99%. Muri rusangi bifatwa nk’uko ibisabwa kugira ngo umuntu ashobore kwaguka neza bivuye ku nzira y’ugusohoka kw’amahasa ni: igipimo co gutera ibice kiri munsi ya 1%, igipimo c’ibihimba bireremba (igipimo co kuzunguruka) kigera kuri 100%, ibihimba vy’umubiri bikozwe mu buryo bumwe kandi bifise ubushobozi bwo guhangana n’amazi; ibifungurwa bireremba bigumizwa mu mazi amasaha 10, kandi ubwoko bw’ugukorora buguma mu mazi amasaha 3 ata gusenyuka kw’isenyuka{8}}
Ivyo bikoresho vy’amahasa vy’abahinguzi batandukanye bifise ubuzima butandukanye kubera ibiranga imiterere itandukanye n’ibikoresho vyakoreshejwe . Ni co gituma, igihe uhitamwo extruder y’amahasa, umuntu akwiye kwitwararika cane nimba umugambi w’imiterere ubereye, kandi ikintu nyamukuru ni ukwambara ibihimba vyambara be n’uko imyambaro y’ivyuma ishobora kugabanywa.
