Makina a jumbo bag un-loader (ton bag un-loader) ndi chida chothyola chikwama chodziwikiratu chomwe chimapangidwira kuthyola thumba lopanda fumbi la zida za tani zomwe zimakhala ndi ufa wapamwamba kwambiri komanso ufa woyenga kwambiri womwe ndi wosavuta kupanga fumbi.Sichidzatulutsa fumbi panthawi yonse ya opaleshoni kapena kuipitsidwa ndi zochitika zina zosafunika, ntchito yonseyi ndi yosavuta, ndipo ndiyosavuta kuwongolera.Chifukwa cha mawonekedwe a modular, palibe mbali yakufa pakuyika, ndipo kuyeretsa ndikosavuta komanso mwachangu.
Chikwama cha jumbo chosanyamula makina chimapangidwa ndi chimango, thumba lakuthyola thumba, chowotcha magetsi, chosonkhanitsa fumbi, valavu yodyetsera yozungulira (valavu imayikidwa malinga ndi zofunikira za ndondomeko yotsatira), ndi zina zotero. imayikidwa pamtengo wa chimango chapamwamba, kapena ikhoza kukhazikitsidwa pansi;Thumba la tani limakwezedwa ndi chokweza chamagetsi pamwamba pa hopper, ndipo thumba pakamwa limafikira ku doko lodyera la hopper, kenako kutseka thumba lachikwama, kumasula chingwe chomangira thumba, tsegulani pang'onopang'ono valavu yotseketsa thumba, ndi zinthu zomwe zili m'thumba zimalowa mu hopper bwino.Chophimbacho chimatulutsa zinthuzo ku valavu yozungulira pansi ndikulowa pansi.Mpweya woponderezedwa wochokera ku fakitale ukhoza kunyamula zinthuzo kupita kumalo komwe ukupita kukamaliza kutumiza zinthu m'thumba la tani (ngati palibe mpweya wofunikira, valavu iyi ikhoza kuchotsedwa).Pakuti processing wa zipangizo zabwino ufa, makinawa akhoza anamanga-mkati kapena kunja olumikizidwa kwa wotolera fumbi, kuti zosefera fumbi kwaiye potaya ndondomeko, ndi kutulutsa mpweya utsi woyera mu mlengalenga, kuti ogwira ntchito gwirani ntchito mosavuta pamalo aukhondo.Ngati ikugwira ntchito ndi zida zoyera za granular ndipo fumbi liri lochepa, cholinga chochotsa fumbi chikhoza kutheka mwa kuyika chinthu chosefera cha poliyesitala pa doko lotulutsa mpweya, popanda kufunikira kwa wotolera fumbi.
