Ntxiv me me ntawm lwm cov kuab tshuaj rau lub tshuab nqus tsev concentration tuaj yeem hloov nws lub peev xwm los yaj cov kuab tshuaj

Ntxiv me me ntawm lwm cov kuab tshuaj rau lub tshuab nqus tsev concentration tuaj yeem hloov nws lub peev xwm los yaj cov kuab tshuaj

Ntxiv rau qhov siab thiab qhov kub thiab txias, qhov sib ntxiv me me ntawm lwm cov kuab tshuaj rau cov kua dej supercritical kuj tuaj yeem hloov nws lub peev xwm los yaj cov kuab tshuaj. Nws cov mechanism ntawm kev txiav txim tseem tsis tau elucidated tag nrho. Feem ntau cov nyiaj ntxiv tsis ntau tshaj 10 feem pua, thiab cov kuab tshuaj polar xws li methanol thiab isopropanol feem ntau yog siv. Ntxiv ib qho me me ntawm cov kuab tshuaj polar tuaj yeem nthuav dav ntxiv ntawm daim ntawv thov ntawm supercritical extraction thev naus laus zis rau ntau lub teb chaws polar.

Nta ntawm ib qho nyhuv concentrator

1. Kev haus cawv rov qab: Lub peev xwm rov qab yog qhov loj, thiab cov txheej txheem nqus dej tau txais yuav. Piv nrog rau cov khoom qub ntawm tib hom, cov khoom tsim tau nce los ntawm 5-10 zaug, thiab kev siv hluav taws xob tau txo los ntawm 30 feem pua. Nws muaj cov yam ntxwv ntawm kev nqis peev me me thiab kev rov ua haujlwm siab.

2. Cov khoom siv ua kua: Cov cuab yeej siv no tau txais kev sib xyaw ua ke ntawm cov cua sov sab nraud thiab lub tshuab nqus tsev tsis zoo evaporation. Lub evaporation ceev ceev, thiab qhov concentration ratio tuaj yeem ncav cuag 1.3. Cov khoom ua kua yog concentrated yam tsis muaj npuas nyob rau hauv lub xeev kaw tag nrho. Nws muaj cov yam ntxwv ntawm tsis muaj kuab paug thiab muaj zog tshuaj tsw qab, thiab nws yog ib qho yooj yim los ntxuav (qhib lub sab sauv thiab sab npog ntawm lub rhaub kom huv si). Cov cuab yeej siv tau yooj yim rau kev khiav lag luam thiab nyob hauv ib cheeb tsam me me. Lub tshuab rhaub thiab evaporator yog ua los ntawm stainless hlau thermal rwb thaiv tsev qauv, lub plhaub sab nrauv ntawm lub thermal rwb thaiv tsev txheej yog ua los ntawm stainless hlau ntawv, thiab saum npoo yog kho nrog daim iav los yog matt.

Vacuum concentration khoom Supercritical extraction nta:

Tsis tshua muaj kub tseem ceeb, haum rau extraction thiab purification ntawm tshav kub-sensitive tebchaw

Nws tuaj yeem muab qhov chaw tsis muaj zog kom tsis txhob muaj cov khoom oxidation thiab tsis cuam tshuam rau cov khoom xyaw nquag ntawm cov extract

Kev tshem tawm ceev ceev, tsis muaj tshuaj lom, tsis muaj hluav taws kub, nyab xeeb siv, thiab tsis ua paug ib puag ncig

Tsis muaj cov kuab tshuaj residue, tsis muaj nitrate thiab hnyav hlau ions

Technical indicators, As supercritical CO2 kua extraction device

Cov cuab yeej yog tsim los ntawm kev rho tawm hluav taws xob, hluav taws xob sib cais, kem kho, CO2 lub twj tso kua mis siab, lub twj tso kua mis, tub yees system, CO2 cia tank, cua kub hloov pauv, purifier, flow meter, kub tswj qhov system, siab tswj thiab kev tiv thaiv kev nyab xeeb ( electrode taw tes tswj, kev ruaj ntseg valve tswj) system muaj pes tsawg leeg.
