Molecular distillationndi luso lapadera lamadzimadzi-lamadzi olekanitsa, lomwe ndi losiyana ndi distillation yachikhalidwe yomwe imadalira pa mfundo yolekanitsa kusiyana kwa mfundo yowira. Iyi ndi njira ya distillation ndi kuyeretsedwa kwa kutentha tcheru zinthu kapena mkulu otentha mfundo zakuthupi ntchito kusiyana kwa njira yaulere ya maselo kuyenda pansi pa vacuum mkulu. Amagwiritsidwa ntchito makamaka mu mankhwala, mankhwala, petrochemical, zonunkhira, mapulasitiki ndi mafuta ndi minda ina mafakitale.
Zinthuzo zimasamutsidwa kuchokera ku chotengera chodyera kupita ku distillation yayikulu yokhala ndi evaporator. Kupyolera mu kuzungulira kwa rotor ndi kutentha kosalekeza, madzi amadzimadzi amapangidwa kukhala filimu yamadzimadzi yopyapyala kwambiri, ndi chipwirikiti, ndikukankhira pansi mozungulira. Pakutsika, zinthu zopepuka (zokhala ndi malo otsika otentha) m'madzi amadzimadzi zimayamba kusungunuka, kupita ku condenser yamkati, ndikukhala madzi otsikira ku botolo lowala. Zida zolemera (monga chlorophyll, mchere, shuga, waxy, ndi zina zotero) sizimasungunuka, m'malo mwake, zimayenda m'kati mwa khoma la evaporator kupita ku botolo lolemera lomwe limalandira.
