Arotary evaporator(rotary evaporator lossis / rotary evaporator) yog ib qho cuab yeej siv hauv cov chaw soj nstuam chemistry rau kev tshem tawm cov kuab tshuaj los ntawm cov qauv los ntawm kev ua kom zoo thiab maj mam tshem tawm.
Lub hom phiaj ntawm distillation yog cais ib qho kev sib tov rau hauv nws cov khoom raws li lawv cov kev hloov pauv hauv cov txheej txheem ntawm evaporation thiab condensation (kua-vapor-kua).
Peb siv rotary evaporators rau ob lub hom phiaj tseem ceeb: 1) kom mloog zoo cov khoom xyaw uas tsis yog-volatile nyob rau hauv ib tug sib tov (piv txwv li, kom concentrate lub purest thiab freshest tsw nyob rau hauv cov ntshav txiv kab ntxwv los ntawm kev tshem tawm dej), thiab 2) kom extract volatile aroma thiab Flavor maj mam muab rho tawm. molecules los ntawm kev sib tov ntawm qhov kub thiab txias (piv txwv li, rho tawm qhov xav tau tsw los ntawm kev sib xyaw ntawm cawv, tshuaj ntsuab, thiab txiv hmab txiv ntoo yam tsis muaj cua sov sib xyaw).
Tus yuam sij rau kev nkag siab txhua qhov distillation yog nco ntsoov tias nws yog kev sib cais. Qab Zib, acid, colorings thiab feem ntau iab tebchaw yog cais los ntawm aroma, cawv, dej thiab me me molecule flavors thiab lwm yam. Qhov zoo tshaj plaws txog rotary evaporation distillation, as opposed to standard distillation, yog tias nws cais cov khoom noj sib txuas ntawm ib leeg yam tsis hloov lawv.
Ob lub ntsiab lus tseem ceeb ntawm cov evaporator rotary tso cai rau kev maj mam, meej thiab ua tau zoo distillation tsis pom nyob rau hauv cov khoom siv distillation: 1) tshem tawm cov kuab tshuaj nyob rau hauv lub tshuab nqus tsev, uas txo nws cov boiling point, tshem tawm qhov yuav tsum tau rau high-kub distillation; 2) evaporation flask Spinning (immersing nyob rau hauv ib da dej kub da dej) tsub kom qhov chaw ntawm cov khoom, zoo heev speeding distillation, thiab sib tov sib xyaw thiab heats cov sib tov los ntawm yuam convection los txhawb kev ruaj khov, txawm evaporation.
Lwm qhov txiaj ntsig ntawm chav kuaj-hom tseem yog qhov chaw kuaj condenser yog kaw thiab ua los ntawm iav, ua rau nws yooj yim rau kev pom thiab kho. Yog li, peb tuaj yeem rov ua dua yuav luag 100% ntawm cov kuab tshuaj.
