I-vacuum concentrator enempembelelo ephindwe kabini yinto egcina amandla endalo yokufudumeza ukujikeleza kwe-evaporation kunye nezixhobo zoxinaniso, ezinokukhupha ngokukhawuleza kwaye zigxininise kwizinto ezahlukeneyo zolwelo kwiqondo lokushisa eliphantsi phantsi kwe-vacuum yoxinzelelo olubi, ngokufanelekileyo ukwandisa ukuxinwa kwezinto zolwelo. Esi sixhobo silungele ukugxininiswa kobushushu obuphantsi kwezinye izinto ezithintela ukushisa kunye nokubuyiswa kwee-solvents eziphilayo ezifana notywala. Ineempawu ezicacileyo ezifana nokonga amandla, ukusebenza kakuhle okuphezulu kunye nokusetyenziswa okubanzi. Isetyenziswe kwiinkalo ezininzi ezifana ne-biopharmaceutical, ukutya kunye nesiselo, ishishini lemichiza emihle, ubunjineli bokukhusela indalo, njl.
Ukubuyiswa kwe-Ethanol: Umthamo wokubuyisela ulungelelaniswa, kwaye ugxininiso lwe-vacuum luyasetyenziswa. Ukusebenza kwemveliso kumaxesha angama-5-10 aphezulu kunezixhobo ezindala zohlobo olufanayo, kwaye ukusetyenziswa kwamandla kuncitshiswa ngama-30%. Ineempawu zeendleko eziphantsi zotyalo-mali kunye nezinga eliphezulu lokubuyisela.
