Mukugadzirwa kwemapepa emazuva ano, anonyanya kushandiswa mapeji emarara uye mhandara pulp, asi dzimwe nguva marara bepa uye mhandara pulp hazviwanikwe mune imwe nzvimbo, zvakaoma kuwana kana kudhura zvakanyanya kutenga, muchiitiko ichi, mugadziri anogona kufunga nezvekushandisa mashanga egorosi seyakabikwa kugadzira bepa, uswa hwegorosi chinhu chakajairika ne-chigadzirwa mune zvekurima, iyo yakawanda isingadhuri.
Kuenzaniswa nehuni faibha, huswa hwegorosi hwakanyanya crispy uye husina kusimba, hazvisi nyore kuchena chena, saka kazhinji, huswa hwegorosi hunowanzo shandiswa kugadzira bepa rinopfachuka kana marata, imwe chigayo chakavhenganiswa gorosi nehuswa nehusina mhandara kana marara kuti ibudise yakaderera mhando yepepa kana bepa rehofisi rinotariswa kuti kugadzirwa kwepepuru. maitiro ari nyore uye mutengo wekugadzira wakaderera.
Kuti ibudise mapepa, uswa hwegorosi hunofanira kutanga kutemwa, kureba kwe20-40mm kunosarudzwa, zviri nyore kuti uswa huendeswe kana kusanganiswa nemakemikari ekubika, muchina wekucheka uswa wegorosi unokumbirwa kuita basa racho, asi nekuchinja kweindasitiri yezvekurima yemazuva ano, gorosi rinowanzokohwewa nemichina, munyaya iyi, muchina wekucheka haufungidzirwe zvakakodzera. Mushure mekucheka, uswa hwegorosi huchaendeswa kuti husanganise nemakemikari ekubikisa, caustic soda yekubika nzira inowanzoshandiswa mukuita uku, kudzikamisa mari yekubika, mvura yedombo reraimu inogonawo kutariswa. Mushure mokunge mashanga egorosi akanyatsosanganiswa nemishonga yekubikira, ichaendeswa kune spherical digester kana pasi pevhu yekubikira dziva, nokuda kwekubika diki mbishi, pasi pevhu yekubikira dziva rinokurudzirwa, kuvakwa kwebasa rehurumende, mari shoma, asi yakaderera. Kune yakakwirira yekugadzira kugona, unofanirwa kufunga nezve kushandisa spherical digester kana contiguous yekubika mudziyo, mukana wekubika kubika, asi hongu, mutengo wemidziyo ungakwira zvakare. Iyo yepasi pevhu yekubikira dziva kana spherical digester yakabatana nemhepo inopisa, nekuwedzera kwekushisa mumudziyo kana tangi uye kusanganiswa kwekubika mumiriri, lignin uye fiber zvichaparadzaniswa. Mushure mekubika, uswa hwegorosi huchaburutswa kubva mumudziyo wekubikira kana tangi yekubikira kuenda kubhini rekuputira kana sediment tank yakagadzirira kuburitsa faibha, muchina unowanzo shandiswa kuchenesa muchina, muchina wekugezesa mbichana kana bivis extruder, kusvika panguva iyoyo gorosi remashanga richanyatsoburitswa, mushure memaitiro ekunatsa uye kuongorora, ichashandiswa kugadzira bepa. Kunze kwekugadzira mapepa, gorosi mashanga faibha inogona zvakare kushandiswa kugadzira tireyi yehuni kana kuumba tirayi yezai.
