Distillation yog tshuaj txheej txheem qhov twg muaj kev sib xyaw ua ke ntawm ob lossis ntau dua cov kua (hu ua "cov khoom siv") nrog cov ntsiab lus kub sib txawv tuaj yeem sib cais los ntawm ib leeg. Tom qab ntawd lub vapor yog nkag mus rau hauv lub condenser, uas ua rau lub vapor txias thiab hloov nws rov qab mus rau hauv cov kua uas hu ua distillate '.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov txheej txheem ntawm distillation?

Cov txheej txheem ntawm distillation pib nrog cua sov cov kua rau boiling point. Cov kua evaporates, tsim ib vapor. Cov vapor yog tom qab ntawd txias, feem ntau dhau los ntawm cov kav dej lossis cov raj ntawm qhov kub qis dua. Yog tias cov tebchaw no muaj cov ntsiab lus kub sib txawv, koj tuaj yeem cais lawv siv distillation.

Qhov thib ob, dab tsi yog ob txheej txheem hauv distillation? Distillation refining muaj ob txheej txheem ntawm distilling thiab condensation reflux. Distillation feem ntau yog nqa tawm hauv distillation kem, gas-kua ob -phase ntws los ntawm kev sib cuag countercurrent, theem kub thiab huab hwm coj hloov.

Tsis tas li ntawd, 3 kauj ruam ntawm distillation yog dab tsi?

Zuag qhia tag nrho txheej txheem ntawm cawv distillation tuaj yeem suav nrog 3 qhov chaw: fermentation, Distillation , thiab Ua tiav.
