Zida angagwiritsidwe ntchito mankhwala, chakudya, makampani mankhwala ndi mafakitale ena kwa ndende ndi distillation yaing'ono mtanda wa zinthu zamadzimadzi ndi kuchira zosungunulira organic, komanso evaporation kuchira kupanga madzi zinyalala. Imagwiritsidwa ntchito makamaka pakupanga oyendetsa kapena labotale Test Research yamabizinesi omwe ali ndi mphamvu zochepa zopanga. Zipangizozi zimatha kugwiritsidwa ntchito movutikira kapena kupanikizika kwamlengalenga, ndipo zitha kugwiritsidwanso ntchito popanga mosalekeza kapena pakanthawi kochepa. Ikhoza kugwiritsidwa ntchito pazinthu zosiyanasiyana ndipo imakhala ndi mphamvu zambiri.Thanki ya ndende yozungulira imakhala ndi thupi lalikulu, condenser, separator ya nthunzi yamadzimadzi ndi mbiya yolandira madzi. Angagwiritsidwe ntchito ndende ndi distillation wa chakudya madzi ndi kuchira zosungunulira organic mu mankhwala, chakudya ndi mankhwala mafakitale. Chifukwa cha kugwiritsidwa ntchito kwa vacuum ndende, nthawi yoyikirapo ndi yaifupi ndipo zida zogwira mtima zazinthu zokhudzidwa ndi kutentha sizidzawonongeka. Zida ndi zida zolumikizirana zidapangidwa ndi chitsulo chosapanga dzimbiri, zokhala ndi kukana kwa dzimbiri komanso kulimba.
