Cov roj residual nyob rau hauv soybean pluas mov yog qhov tseem ceeb cuam tshuam rau cov roj yield hauvsoybean roj hnyav extraction kab. Yam tseem ceeb uas cuam tshuam rau cov roj seem noj zaub mov suav nrog cov cuab yeej siv, thev naus laus zis, ua ntej- kev kho mob thiab kev ua haujlwm ntawm cov neeg ua haujlwm. Nov yog ib qho kev txheeb xyuas luv luv ntawm qee yam cuam tshuam rau cov zaub mov residual roj:
1. Lub sijhawm ua haujlwm
Thaum cov roj thiab cov kuab tshuaj tuaj rau hauv kev sib cuag, raws li lub hauv paus ntsiab lus ntawm cov miscibility zoo sib xws, roj thiab cov kuab tshuaj yaj mus rau hauv ib leeg. Hauv cov txheej txheem no, cov roj molecules raug xa mus rau cov kuab tshuaj, thiab cov kuab tshuaj molecules tseem raug xa mus rau cov roj kom txog thaum cov concentrations ntawm cov kuab tshuaj nyob rau hauv ob-thev cov kuab tshuaj yog tib yam thiab muaj qhov sib npaug sib npaug. Nyob rau hauv cov txheej txheem leaching ntau lawm, peb feem ntau siv cov countercurrent leaching txoj kev, uas yog, nyob rau hauv cov khoom siv leaching, tsis tu ncua nkag mus rau cov roj yog maj mam leached nrog cov roj sib xyaw ntawm maj dilute concentration, thiab thaum kawg, cov kuab tshuaj tshiab yog siv los leaching cov roj uas tsis tshua muaj residual roj, thiab yuav luag tag nrho cov roj nyob rau hauv cov roj yog leached tawm. Raws li txoj cai, nws yog qhov zoo tshaj plaws rau txhua qhov leaching kom ncav cuag lub dynamic equilibrium. Txawm li cas los xij, vim muaj kev txwv cov cuab yeej siv, txhua qhov leaching tsuas yog tuaj yeem mus txog tab sis tsis ncav cuag qhov sib npaug sib npaug. Yog li ntawd, qhov ntev ntawm leaching lub sij hawm yog qhov tseem ceeb ntawm no. Hauv kev tsim khoom tiag tiag, peb tuaj yeem txo cov roj seem hauv cov pluas noj rau qee qhov los ntawm kev txo qis kev khiav hauj lwm ceev ntawm cov khoom siv leaching, ua kom qhov siab ntawm cov khoom txheej, thiab ncua sij hawm leaching.
2. Solvent ratio
Qhov hnyav piv yog hais txog qhov sib piv ntawm qhov hnyav rau cov khoom siv thaum muab cov roj los ntawm cov khoom leached.
Thaum cov kuab tshuaj sib piv loj, cov concentration ntawm cov roj sib xyaw uas tsim tawm thaum lub sij hawm leaching yog tsawg, qhov sib txawv ntawm cov kuab tshuaj thiab cov roj nyob rau hauv kev sib nrig sib hloov txheej txheem yog loj, thiab loj hloov ceev ceev, yog li lub sij hawm yuav tsum tau rau leaching nyob rau hauv tib lub sij hawm luv luv. Ntawm qhov tsis sib xws, thaum qhov hnyav piv me me, qhov loj hloov ceev ntawm cov kuab tshuaj thiab cov roj yuav txo qis, thiab lub sijhawm rho tawm yuav ntev dua nyob rau hauv tib lub sijhawm. Hauv cov txheej txheem tsim khoom tiag tiag, vim muaj kev cuam tshuam ntawm ntau yam xws li khoom siv, kev tiv thaiv ib puag ncig, thiab cov txiaj ntsig kev lag luam, qhov hnyav piv tsis tuaj yeem nce infinitely. Yog li ntawd, qhov sib piv ntawm cov kuab tshuaj yuav tsum tau tswj nyob rau hauv ib tug tsim nyog ntau yam, uas yuav tsis tau tsuas yog ua tau raws li cov kev xav tau ntawm kev tsim khoom thiab kev tiv thaiv ib puag ncig, tab sis kuj txo cov nqi tsim khoom. Yog tias muaj kev tso cai, tsim nyog nce cov tshuaj hnyav tshiab tuaj yeem txo cov roj seem ntawm cov pluas noj rau qee yam.
3. Leaching kub
Qhov kub ntawm cov txheej txheem leaching yog txiav txim siab los ntawm cov khoom siv kub, hnyav kub thiab qhov sib piv ntawm lawv qhov ntau. Qhov kub ntawm cov txheej txheem leaching muaj qhov cuam tshuam zoo rau kev ceev thiab cuam tshuam ntawm leaching. Thaum qhov kub thiab txias, qhov tsis sib haum xeeb ntawm cov molecules muaj zog, qhov viscosity ntawm cov kuab tshuaj thiab cov roj txo qis, kev ua haujlwm ntawm cov roj molecules thiab cov kuab tshuaj molecules txo qis, kev hloov ceev ntawm cov molecules yog nce, lub sij hawm yuav tsum tau ua kom tiav dynamic tshuav nyiaj li cas yuav txo tau, thiab theoretically cov ntsiab lus ntawm residual roj nyob rau hauv cov zaub mov yuav txo tau. Txawm li cas los xij, qhov kub thiab txias yog txwv los ntawm qhov pib boiling point ntawm cov kuab tshuaj thiab qhov pib boiling point ntawm cov roj sib xyaw thiab tsis tuaj yeem nce arbitrarily. Ntawd yog, qhov kub ntawm cov txheej txheem leaching yuav tsum tsis txhob tshaj qhov kub ntawm cov kuab tshuaj thiab cov roj sib xyaw. Txwv tsis pub, ntau cov kuab tshuaj yuav vaporize, uas yuav txo tau cov leaching hnyav piv thiab ua rau kom lub siab nyob rau hauv cov khoom leaching. Hauv kev ua haujlwm tiag tiag, lub extractor tsuas yog xav tau lub xeev siab me ntsis. Raws li kev thauj khoom ntawm cov pa hluav taws xob kho thiab lwm yam kev mob, nce qhov kub thiab txias nyob rau hauv qee qhov ntau kuj tuaj yeem txo cov roj seem hauv cov pluas noj rau qee yam.
Cov saum toj no yog ob peb yam tseem ceeb uas cuam tshuam cov roj seem hauv cov pluas noj thaum lub sij hawm ua haujlwm leaching txhua hnub. Tsis tas li ntawd, yam xws li hom khoom siv leaching, cov khoom siv ua ntej - cov txheej txheem kho, cov ntsiab lus noo noo thiab hmoov piv kuj tseem ceeb heev rau kev cuam tshuam ntawm cov khoom noj uas muaj roj. Yog tias koj xav paub ntau ntxiv txog cov txheej txheem roj leaching thiab cov khoom siv, thov hu rau peb sai sai!
