Vacuum concentration: ho ntlafatsa ts'ebetso ea ts'ebetso ea indasteri

Vacuum concentration ke mokhoa o sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri ho tlosa mokelikeli o feteletseng kapa solvent ho lisampole kapa tharollo. Mokhoa ona o boetse o tsejoa e le vacuum evaporation, 'me o sebetsa tlas'a khatello e fokotsehileng, e leng ho etsang hore mouoane o sebetse hantle le ka potlako ho feta mekhoa e tloaelehileng. Sehloohong sena, re tla hlahloba melao-motheo ea ts'ebeliso ea vacuum le ts'ebeliso ea eona liindastering tse fapaneng.

Mokhoa oa khatello ea vacuum:

Molao-motheo oa vacuum concentration ke ho theola ntlha e belang ea mokelikeli ka khatello e tlase. Ka ho fokotsa khatello tsamaisong e koetsoeng, ntlha e belang ea tharollo e theoleloa 'me mokelikeli o fetoha mouoane habonolo. Vacuum concentrator e na le pompo ea vacuum e hlahisang le ho boloka khatello e hlokahalang, mohloli oa mocheso o laoloang o fanang ka matla a ho fetoha mouoane, le condenser e bokellang le ho khutlisetsa solvent e mouoane.

Melemo le ts'ebeliso ea khatello ea vacuum:

1. Mouoane o sebetsang hantle le o potlakileng: Tlhophiso ea vacuum e potlakisa haholo ts'ebetso ea mouoane, e lumellang ho tlosoa ha solvent ka potlako ha ho bapisoa le mekhoa e tloaelehileng. Ts'ebetso ena e eketsehileng e boloka nako le matla, e etsa hore e be theknoloji e loketseng liindasteri tse fapaneng.

2. Motsoako oa maro a baballang mocheso: Mekelikeli e meng e khona ho utloa mocheso o phahameng 'me e tla bola kapa e lahleheloe ke thepa ea eona e hlokahalang ha ho sebelisoa mekhoa e tloaelehileng ea ho futhumatsa. Vacuum concentration e sebetsa maemong a mocheso a tlase, e fokotsa kotsi ea ho senyeha le ho netefatsa hore boleng bo lakatsehang boa bolokoa.

3. Solvent recovery: Vacuum concentration (vacuum) e ka hlaphoheloa habonolo le ho e sebelisa hape. Sehlapi sa mouoane se ka koaheloa le ho bokelloa bakeng sa ho sebelisoa hape, ho boloka litšenyehelo le ho fokotsa tšusumetso ea tikoloho.

4. Indasteri ea meriana: Vacuum concentration e phetha karolo ea bohlokoa tlhahisong ea meriana hobane e thusa ho tlosoa ha li-solvents litokisetsong tsa meriana le ho potlakisa ho omisoa ha li-intermediate tsa meriana. Theknoloji ena e tiisa polokeho, bohloeki le boleng ba sehlahisoa sa ho qetela.

5. Ts'ebetso ea lijo: Vacuum concentration e sebelisoa haholo indastering ea lijo ho tlosa mongobo o feteletseng ho tsoa lijong tse metsi kapa tse tiileng. Ts'ebetso ena e thusa ho tsepamisa maikutlo ho lero, li-syrups le li-sauces, ho ntlafatsa tatso ea tsona le ho lelefatsa bophelo ba tsona.

6. Lisebelisoa tsa tikoloho: Litsi tsa ho hloekisa metsi a litšila li sebelisa "vacuum concentration" ho tlosa metsi a mangata ho tsoa metsing a litšila a indasteri, ka hona ho fokotsa bongata ba litšila. Mokhoa ona ha o thuse feela ho fokotsa tšilafalo ea tikoloho empa o boetse o fumana lisebelisoa tsa bohlokoa tse tsoang moketjaneng oa litšila.

7. Ho etsa lik'hemik'hale: Ho kenngoa ha vacuum ho sebelisoa haholo ts'ebetsong ea tlhahiso ea lik'hemik'hale. E thusa ho tlosa li-solvents ho tsoa mefuteng e fapaneng ea lik'hemik'hale, e hlahisang metsoako e hloekileng le e tsitsitseng. Theknoloji ena e bohlokoa ka ho khetheha bakeng sa lintho tse thibelang mocheso kapa tse senyang.

Ka kakaretso, khatello ea vacuum ke mokhoa o sebetsang oa ho tlosa mokelikeli o mongata kapa mokelikeli linthong tse fapaneng 'me o sebelisoa haholo liindastering tse kang tsa meriana, ho lokisa lijo, ho etsa lik'hemik'hale le ho hloekisa metsi a litšila. Bokhoni ba eona ba ho potlakisa mouoane, ho fokotsa ho pepeseha ha mocheso le ho thusa ho hlaphoheloa ha solvent ho etsa hore e be letlotlo la bohlokoa bakeng sa ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo le ho netefatsa boleng ba sehlahisoa sa ho qetela. Ka tsoelo-pele e tsoelang pele le lintlafatso, khatello ea vacuum e tla lula e le thekenoloji ea bohlokoa lits'ebetsong tse ngata tsa indasteri lilemong tse tlang.
