Organic acids yog dav nyob rau hauv nplooj, cov hauv paus hniav thiab tshwj xeeb tshaj yog txiv hmab txiv ntoo ntawm Suav tshuaj ntsuab tshuaj.Cov kua qaub tshaj plaws yog carboxylic acids, cov kua qaub uas yog los ntawm pawg carboxyl (-COOH).Ntau cov organic acids yog ib qho tseem ceeb ntawm cov khoom siv raw, xws li citric acid, dibasic acid, lactic acid, itaconic acid thiab lwm yam.Nrog rau qhov kev thov ntau ntxiv rau cov organic acids, yuav ua li cas txo cov nqi tsim khoom, txhim kho cov khoom zoo, thiab txuag lub zog thiab txo cov emissions tau dhau los ua qhov tseem ceeb ntawm cov lag luam.Yog li ntawd, optimizing cov txheej txheem rho tawm ntawm cov organic acids tau dhau los ua ib qho kev sib tw tseem ceeb rau cov tuam txhab organic acid.Niaj hnub no, tus editor ntawm Shandong Bona Group yuav qhia txog daim ntawv thov ntawm daim nyias nyias nyias tshuab hauv kev tsim cov organic acids.
Raws li ib qho ntawm cov thev naus laus zis ua ntej rau kev sib cais thiab tshem tawm ntawm citric acid, ultrafiltration technology yog ib txoj hauv kev tshiab uas tsuas yog tshwm sim hauv xyoo tas los no.Nws yog ib txoj kev kuaj lub cev yooj yim.Nws tuaj yeem siv los tshem tawm thiab cais cov impurities xws li cov protein, suab thaj, thiab pigments hauv cov lim.Tus yuam sij rau txoj kev no yog xaiv ultrafiltration daim nyias nyias nrog zoo oxidation tsis kam thiab acid tsis kam.Membrane sib cais thiab pom cov organic acid fermentation broth kom tshem tawm macromolecular proteins, colloids, kab mob, polysaccharides thiab lwm yam impurities nyob rau hauv lub fermentation broth ntawm molecular theem.Lub filtrate muaj siab clarity thiab siab purity ntawm cov organic acids.Nws yog qhov tsim nyog rau kev tswj cov dej phwj tuaj tom ntej thiab txhim kho cov khoom zoo thiab tawm los.
Cov txheej txheem ntawm extracting organic acid los ntawm ultrafiltration txoj kev:
Organic acid fermentation broth pretreatment → ultrafiltration → crystallization → centrifuged niam cawv → ziab → khoom tiav
Qhov zoo ntawm cov organic acid membrane sib cais tshuab:
1. Membrane sib cais tshuab hloov cov txheej txheem phaj-thiab-thav duab filtration, qhia meej txog fermentation broth, txhim kho qhov zoo ntawm cov filtrate, thiab txo cov pa phem nyob rau hauv lub tom ntej;
2. Cov khoom siv membrane ua haujlwm ntawm chav tsev kub, txuag lub zog yam tsis muaj kev puas tsuaj rau cov khoom siv hauv cov khoom;
3. Tsis tas yuav ntxiv cov tshuaj, cov kuab tshuaj, thiab cov pa phem thib ob hauv cov txheej txheem pom;
4. Membrane system cov ntaub ntawv yog tag nrho ua los ntawm cov zaub mov huv qib stainless hlau, tag nrho cov kav raj xa dej ua haujlwm, thiab ua tau raws li qhov yuav tsum tau ua ntawm GMP ntau lawm specifications.Lub kaw lus tau txais kev tsim qauv tsim, uas nyob hauv pem teb tsawg dua thiab muaj qhov tsim nyog;
5. Cov ntaub ntawv membrane thiab cov khoom siv pabcuam yog cov khoom tsis muaj kuab paug, raws li QS thiab GMP cov cai.
Bona Bio yog cov chaw tsim khoom tshwj xeeb hauv kev tsim cov khoom siv sib cais membrane.Nws muaj ntau xyoo ntawm kev tsim khoom thiab kev paub dhau los, tsom mus rau kev daws qhov teeb meem ntawm kev pom thiab kev mloog zoo hauv cov txheej txheem ntawm cov khoom siv roj ntsha fermentation / dej haus / tshuaj suav tshuaj / tsiaj txhu thiab cov nroj tsuag extraction.Txoj kev tsim cov voj voog tuaj yeem pab cov neeg siv khoom txhim kho kev tsim khoom thiab ua tiav cov khoom siv huv.Yog tias koj ntsib teeb meem hauv daim nyias nyias, thov koj xav tiv tauj peb, peb yuav muaj cov kws tshaj lij los teb rau koj.
