Subcritical extraction technology ntawm hnub noob roj
Nyob rau hauv qee qhov siab, cov khoom siv yog countercurrent extraction nrog liquefied sub-critical hnyav, thiab cov kuab tshuaj nyob rau hauv cov kua extraction mus los ntawm cov txheej txheem evaporation, kom cov kuab tshuaj vaporizes thiab cov extracted lub hom phiaj yog sib cais kom tau cov khoom; Cov khoom rho tawm evaporates tawm ntawm qhov adsorbed hnyav, thiab lwm yam khoom tau txais. Cov kuab tshuaj vaporized yog liquefied tom qab compression tshav kub hloov thiab rov siv dua.
Cov txheej txheem rho tawm
1, Ua ntej txheej txheem
Hnub tim noob → Crusher Extraction
2, Kev rho tawm
3, Ua kom tiav
Cov roj Crude → Deacidification → Dehydration + decolorization + deodorization + dewaxing → Cov khoom siv roj tiav
Extraction hnyav: Butane
Lub sijhawm noj mov: 6h / batch
Nta
- Kev rho tawm qhov kub thiab txias, tsis kub dissolving, tsis rhuav tshem cov cua kub rhiab heev hauv cov khoom, tshwj xeeb tshaj yog tsim rau kev rho tawm thiab ua cov ntaub ntawv kub, cov roj tau txais yog cov khoom zoo thiab cov khoom noj muaj txiaj ntsig zoo; Cov tshuaj nquag hauv cov pluas noj tseem nyob ruaj khov, thiab cov khoom lag luam hauv qab tuaj yeem tsim kho ntxiv.
- Cov thev naus laus zis tau paub tab thiab kev ua qauv tsim cov kab tsim tau nyob rau hauv ntau lawm rau 30 xyoo.
- Cov khoom siv yog cov txheej txheem ua haujlwm dav dav, uas tuaj yeem rho tawm cov roj-soluble Cheebtsam hauv ntau yam ntaub ntawv, xws li cov roj ua haujlwm, cov khoom siv tshuaj hauv Suav teb, cov txuj lom, roj-soluble pigments thiab lwm yam.
