Imashini ya jumbo idapakurura (ton bag un-loader) ni ibikoresho byangiza imifuka byikora bigenewe umufuka utagira ivumbi kumena ibikoresho bya toni birimo ifu ya ultra-nziza nifu y-isuku byoroshye kubyara umukungugu.Ntabwo izimena umukungugu mugihe cyibikorwa byose cyangwa kwambuka kwanduza nibindi bintu bitifuzwa, ibikorwa rusange biroroshye, kandi biroroshye kubigenzura.Kuberako igishushanyo mbonera, nta mpande zapfuye mugushiraho, kandi gusukura biroroshye cyane kandi byihuse.
Imashini ya jumbo idapakurura igizwe n'ikadiri, umufuka umena umufuka, kuzamura amashanyarazi, gukusanya umukungugu, kugaburira umukungugu wo kuzunguruka (valve yashyizweho ukurikije ibisabwa mubikorwa bizakurikiraho), nibindi. Bishyizwe kumurongo wurwego rwo hejuru, cyangwa birashobora gushirwa hasi;Umufuka wa toni uzamurwa no kuzamura amashanyarazi hejuru ya hopper, maze umunwa wumufuka ugera ku cyambu cyo kugaburira cya hopper, hanyuma ufunge igikapu gifata igikapu, uhambure umugozi wa karuvati, ufungure buhoro buhoro umufuka ufata valve, ibikoresho biri mu gikapu bitemba muri hopper neza.Hopper isohora ibikoresho kumurongo uzenguruka hepfo hanyuma ikinjira mumuyoboro wo hasi.Umwuka ucanye uva mu ruganda urashobora guhita utwara ibintu aho ujya kugirango urangize gutanga ibikoresho mumifuka ya toni (niba nta kirere gikenewe, iyi valve irashobora kuvaho).Mugutunganya ibikoresho byifu yifu, iyi mashini irashobora kuba yubatswe cyangwa igahuzwa n’ikusanyirizo ryumukungugu, kugirango iyungurure umukungugu waturutse mugihe cyo kujugunya, hanyuma usohokemo gaze yuzuye isukuye mukirere, kugirango abakozi babashe kora byoroshye ahantu hasukuye.Niba ikorana nibikoresho bya granula bisukuye kandi ivumbi riba rito, intego yo gukuraho ivumbi irashobora kugerwaho mugushiraho ikintu cya filteri ya filteri kumurongo wicyuka, bitabaye ngombwa ko hakusanya umukungugu.
