Molecular distillation ua haujlwm ntawm lub hauv paus ntsiab lus ntawm qhov sib txawv txhais tau tias tsis muaj txoj hauv kev ntawm vapor molecules. Ntawm qhov tsis tshua muaj siab, qhov txhais tau tias txoj kev pub dawb ntawm vapor molecules nce ntxiv, cia lawv taug kev ntev dua yam tsis muaj kev sib tsoo nrog lwm cov molecules.
Qhov no tshwm sim yog siv nyob rau hauv molecular distillation los ntawm tsim ib tug nyias zaj duab xis ntawm cov khoom yuav tsum tau distilled rau ib tug rhuab nto. Raws li cov khoom evaporates, lub sib dua, ceev-tsav molecules mus ntxiv tshaj qhov hnyav, qeeb-tsav sawv daws yuav, ua rau lawv sib cais raws li lawv molecular luj thiab vapor velocities. |

Cov txheej txheem molecular distillation feem ntau suav nrog cov kauj ruam hauv qab no
● Kev Taw Qhia Pub:Cov khoom siv raw yog nkag mus rau hauv lub evaporator, qhov chaw uas nws kis tau mus rau hauv ib zaj duab xis nyias ntawm qhov chaw rhuab.
● Evaporation: Cov rhuab saum npoo ua rau cov khoom evaporate, tsim cov vapor uas muaj cov sib xyaw ntawm cov khoom sib txawv.
● Kev sib cais: Lub vapor mus los ntawm qhov luv luv ("txoj kev luv") mus rau lub condenser, qhov chaw sib dua, nrawm dua-tsav molecules condense ua ntej, thaum hnyav dua, qeeb-tsav molecules txuas ntxiv mus. Qhov no ua rau kev sib cais ntawm cov khoom raws li lawv qhov hnyav molecular thiab vapor velocities.
● Sau:Cov condensed lighter Cheebtsam yog sau, thaum lub hnyav Cheebtsam, nrog rau tej unevaporated residue, raug tshem tawm ntawm lub system.
Qhov zoo ntawm Molecular Distillation
Molecular distillation muaj ntau qhov zoo dua li cov txheej txheem distillation, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev sib cais thiab kev ua kom huv ntawm cov cua kub-rhiab, kub kub, thiab muaj txiaj ntsig zoo. Qee qhov txiaj ntsig tseem ceeb ntawm nws muaj xws li:
● Tsawg Kev Ua Haujlwm Siab:Molecular distillation ua haujlwm ntawm qhov tsis tshua muaj siab, uas txo qhov kev pheej hmoo ntawm thermal degradation ntawm cov khoom ua tiav. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov khoom siv hluav taws xob, xws li cov roj yam tseem ceeb, cov tshuaj tsw qab, thiab cov vitamins.
● Cov txheej txheem ua haujlwm maj mam:Lub sijhawm nyob luv luv ntawm cov khoom siv hauv cov evaporator thiab qhov kub tsis tshua muaj qhov xav tau rau evaporation ua kom cov txheej txheem ua haujlwm maj mam khaws cia qhov kev ncaj ncees thiab zoo ntawm cov khoom kawg.
● High Separation Efficiency:Cov txheej txheem sib cais tshwj xeeb raws li qhov sib txawv txhais tau tias tsis muaj txoj hauv kev ntawm vapor molecules ua rau muaj kev sib cais siab, txawm tias cov tebchaw nrog cov ntsiab lus kub kub.
● Kev Siv Hluav Taws Xob:Qhov luv luv taug kev los ntawm cov vapor molecules thiab tsis muaj kev ntxhov siab loj lossis sib xyaw hauv cov evaporator ua rau lub zog ua haujlwm ntawm molecular distillation.
Versatility: Molecular distillation tuaj yeem siv rau ntau yam khoom siv, suav nrog cov ntsiab lus kub kub, tsis tshua muaj vapor pressures, thiab viscosity siab.
