Li-asiti tsa Organic li fumaneha ka bongata makhasi, metso, haholo-holo litholoana tsa meriana ea litlama ea Sechaena.Li-acid tse atileng haholo ke li-carboxylic acid, acidity ea eona e tsoang sehlopheng sa carboxyl (-COOH).Li-acid tse ngata tsa manyolo ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse tala, tse kang citric acid, dibasic acid, lactic acid, itaconic acid joalo-joalo.Ka tlhokahalo e ntseng e eketseha ea li-organic acid, mokhoa oa ho fokotsa litšenyehelo tsa tlhahiso, ho ntlafatsa boleng ba sehlahisoa, le ho boloka matla le ho fokotsa likhase e se e le sepheo sa likhoebo.Ka hona, ho ntlafatsa ts'ebetso ea ho ntšoa ha li-organic acid e se e le e 'ngoe ea mekhoa e ka sehloohong ea tlholisano bakeng sa baetsi ba asiti ea manyolo.Kajeno, mohlophisi oa Shandong Bona Group o tla hlahisa ts'ebeliso ea theknoloji ea karohano ea membrane tlhahiso ea li-organic acid.
Joalo ka e 'ngoe ea mahlale a pele a kalafo bakeng sa karohano le ho ntšoa ha citric acid, theknoloji ea ultrafiltration ke mokhoa o mocha o hlahileng lilemong tsa morao tjena.Ke mokhoa o bonolo oa ho hlahloba 'mele.E ka sebelisoa ho tlosa le ho arola litšila tse kang liprotheine, tsoekere le li-pigments ka har'a filtrate.Senotlolo sa mokhoa ona ke ho khetha li-membrane tsa ultrafiltration tse nang le khanyetso e ntle ea oxidation le ho hanyetsa acid.Membrane karohano le filtration ea manyolo acid belisoa moro ho tlosa ka ho feletseng liprotheine macromolecular, colloids, libaktheria, polysaccharides le litšila tse ling ka belisoa moro boemong ba molek'hule.Filtrate e na le ho hlaka ho phahameng le bohloeki bo phahameng ba li-organic acid.E thusa taolong ea likhoerekhoere tse latelang le ho ntlafatsa boleng ba sehlahisoa le chai.
Mokhoa oa ho ntša organic acid ka mokhoa oa ultrafiltration:
Organic acid fermentation broth pretreatment → ultrafiltration →crystallization → centrifuged joala ea 'm → ho omisa → sehlahisoa se felileng
Melemo ea theknoloji ea karohano ea membrane ea organic acid:
1. Theknoloji ea karohano ea li-membrane e nkela sebaka sa mokhoa o tloaelehileng oa ho hloekisa poleiti le foreimi, e hlakisa moro oa ho belisoa, e ntlafatsa boleng ba filtrate, le ho fokotsa tšilafalo ea resin ka tatellano e latelang;
2. Thepa ea membrane e sebetsa mocheso oa kamore, e boloka matla ntle le ho senya metsoako e sebetsang ea sehlahisoa;
3. Ha ho hlokahale ho eketsa lik'hemik'hale, lihlapolli, le litšila tsa bobeli nakong ea ho hloekisa;
4. Lisebelisoa tsa tsamaiso ea "membrane" kaofela li entsoe ka tšepe ea boleng bo botle ba lijo, ts'ebetso ea liphaephe e koetsoeng ka botlalo, 'me e finyella litlhoko tsa tlhahiso ea tlhahiso ea GMP.Sistimi e amohela moralo o kopaneng oa ts'ebetso, o nkang sebaka se senyenyane sa fatše mme o na le sebopeho se loketseng;
5. Lisebelisoa tsa "membrane" le lisebelisoa tse thusang ke lisebelisoa tse sa silafatsang, tse lumellanang le litlhoko tsa QS le GMP.
Bona Bio ke moetsi ea ikhethileng ka tlhahiso ea lisebelisoa tsa karohano ea membrane.E na le lilemo tse ngata tsa tlhahiso le boiphihlelo ba tekheniki, e shebane le ho rarolla bothata ba ho sefa le ho tsepamisa mohopolo ts'ebetsong ea tlhahiso ea biological fermentation / seno / meriana ea setso ea Machaena / liphoofolo le limela.Mekhoa ea ho hlahisa selikalikoe e ka thusa bareki ka katleho ho ntlafatsa katleho ea tlhahiso le ho finyella tlhahiso e hloekileng.Haeba u ile ua tobana le mathata afe kapa afe a ho sefa membrane, ka kopo ikutloe u lokolohile ho ikopanya le rona, re tla ba le litsebi tsa litsebi ho u araba.
