Organic zidulo ambiri exe mu masamba, mizu makamaka zipatso za Chinese mankhwala azitsamba.Ma acid omwe amapezeka kwambiri ndi ma carboxylic acid, acidity omwe amachokera ku gulu la carboxyl (-COOH).Ambiri organic zidulo zofunika zofunika mankhwala zopangira, monga citric acid, dibasic acid, lactic acid, asidi itaconic ndi zina zotero.Pakuchulukirachulukira kwa ma organic acid, momwe mungachepetsere ndalama zopangira, kukonza zinthu, ndikupulumutsa mphamvu ndikuchepetsa kutulutsa mpweya kwakhala cholinga chachikulu m'mabizinesi.Chifukwa chake, kukhathamiritsa kachulukidwe ka ma organic acid kwakhala njira imodzi yopikisana nawo opanga ma organic acid.Masiku ano, mkonzi wa Shandong Bona Group ayambitsa kugwiritsa ntchito ukadaulo wolekanitsa wa membrane pakupanga ma organic acid.
Monga imodzi mwaumisiri pretreatment kwa kulekana ndi m'zigawo za citric asidi, ultrafiltration luso ndi njira yatsopano kuti anaonekera m'zaka zaposachedwapa.Ndi njira yosavuta yowonera thupi.Itha kugwiritsidwa ntchito kuchotsa ndikulekanitsa zodetsa monga mapuloteni, shuga, ndi ma inki mu kusefera.Chinsinsi cha njirayi ndikusankha ma membrane a ultrafiltration okhala ndi kukana kwa okosijeni bwino komanso kukana kwa asidi.Kupatukana kwa membrane ndi kusefera kwa organic acid nayonso mphamvu msuzi kuchotsa kwathunthu macromolecular mapuloteni, colloids, mabakiteriya, polysaccharides ndi zonyansa zina mu nayonso mphamvu msuzi pa maselo msinkhu.Filtrate imakhala yomveka bwino komanso yoyera kwambiri ya organic acid.Zimathandizira kuwongolera zimbudzi zotsatira ndikuwongolera mtundu wazinthu ndi zokolola.
Njira yochotsera organic acid ndi njira ya ultrafiltration:
Organic acid fermentation msuzi pretreatment→ultrafiltration→crystallization→mowa wa mayi wapakati→kuyanika→chinthu chomaliza
Ubwino waukadaulo wolekanitsa wa organic acid membrane:
1. Ukadaulo wolekanitsa ma membrane m'malo mwa njira yachikhalidwe yosefera mbale-ndi-frame, kumamveketsa bwino msuzi wa fermentation, kumapangitsa kuti sefeyi ikhale yabwino, komanso imachepetsa kuipitsidwa kwa utomoni muzotsatira zotsatizana;
2. Zida za membrane zimagwira ntchito kutentha kutentha, kupulumutsa mphamvu popanda kuwononga zinthu zomwe zimagwira ntchito;
3. Palibe chifukwa chowonjezera mankhwala, zosungunulira, ndi zowonongeka zachiwiri muzosefera;
4. Zida zamakina onse amapangidwa ndi chitsulo chosapanga dzimbiri chaukhondo wa chakudya, ntchito yamapaipi yotsekeredwa bwino, ndikukwaniritsa zofunikira za kupanga kwa GMP.Dongosololi limagwiritsa ntchito mapangidwe ophatikizika, omwe amakhala ndi malo ocheperapo pansi ndipo amakhala ndi masanjidwe oyenera;
5. Zipangizo zamakina ndi zida zothandizira ndizopanda zowononga, zogwirizana ndi zofunikira za QS ndi GMP.
Bona Bio ndi wopanga okhazikika pakupanga zida zolekanitsa za membrane.Ili ndi zaka zambiri zakupanga komanso luso laukadaulo, ikuyang'ana kwambiri kuthana ndi vuto la kusefera ndi kukhazikika pakupanga kwa biological fermentation / chakumwa / mankhwala achi China / nyama ndi mbewu.Njira zopangira zozungulira zimatha kuthandiza makasitomala kuwongolera magwiridwe antchito komanso kupanga zoyeretsa.Ngati munakumana ndi vuto pakusefera kwa membrane, chonde omasuka kutilankhula, tidzakhala ndi akatswiri oti akuyankheni.
