Muchina wepaketi akarongedza anogadzirwa nesimbi isina tsvina, nechitarisiko chakanaka, chimiro chine musoro uye kakawanda tekinoroji yeudiki. Chishandiso chekutambanudza zvinhu zvekupa chikafu panguva yekurongedza. Iyo firimu yepurasitiki inoumbwa muhubhu mune yefirimu cylinder, nepo kusungwa kwekushambadzira kwekupisa uye kwakarongedzwa muhomwe, kuchinjika kwekuputika kunoenderana nemavara kodhi yemidhodhi yemifananidzo.

Iyo yekushanda musimboti wekutarisa muchina ndeyekuti iyo firimu ichaiswa muchina chekutakura Nedura redziviriro yekupisa inosimbisa Chishandiso cheto chinoita kuti chinhu chacho chobva chazadza bhegi rekuzadza tube, ichiteverwa nemusungwa kupisa chisimbiso uye kucheka pakati pekupisa chishandiso chekugadzira chikamu chekuisa, uku uchigadzira inotevera barrel barl sel.
Vertical kurongedza michina inoshandiswa zvakanyanya muhupenyu hwezuva nezuva. Inokodzera kurongedza kweiyo dzakasiyana-siyana powders, granules, mahwendefa nezvimwe zvigadzirwa. Vertical kurongedza michina uye mamwe michina anoonekwa nenyaya yekuti pombi yekuburitsa zvinhu zvinoiswa mukati mehomwe kugadzira muchina, iyo bhegi iri kuita, uye zvinyorwa zvekutakura kubva kumusoro kusvika kumusoro munzira yakatwasuka.

Iyo yekuisa mapepa ekurapa inonyanya kuumbwa neyekuyera mudziyo, kutumira system, yakatwasuka uye yakatwasuka chishandiso chishandiso, kuzadza tube uye kudhonza firimu uye kupa mechanism. Iyo yekugadzira maitiro emuchina wepaketi ekurongedza: Iyo yakatwasuka kurongedza muchina pamwe pamwe nemachina uye kuzadza muchina mumugwagwa. Hunhu hwayo ndehwekuti iyo yekudyisa cylinder yezvinyorwa zvakarongedzwa zvakagadzirwa mukati mehomwe yemugadziri, uye bhegi kugadzira uye kuzadza zvinyorwa zvinoitwa kumusoro kusvika kumusoro kusvika pasi.
