Kuvandudza uye kushandiswa kwemavara echisikigo kwave kunetsa kune vese vashandi vesainzi uye tekinoroji mumaindasitiri akasiyana.Vanhu vanoedza kuwana mavara echisikigo kubva kune akasiyana siyana mhuka nezvirimwa zviwanikwa uye kuongorora zviitiko zvavo zvemuviri kudzikisa uye kugadzirisa matambudziko akasiyana anokonzerwa nekugadzira pigment.Iyo yekubvisa maitiro echisikigo pigment zvakare yakagadziridzwa nekukurumidza, uye ikozvino membrane yekuparadzanisa tekinoroji yave imwe yenzira huru dzekubvisa pigment yechisikigo.
Membrane kupatsanurwa kunosanganisira mana makuru ekuyambuka-kuyerera membrane maitiro: microfiltration MF, ultrafiltration UF, nanofiltration NF, uye reverse osmosis RO.Kupatsanura uye kuchengetedza kuita kweakasiyana membranes kunosiyaniswa nehukuru hwepore uye molecular uremu kucheka-kubvisa membrane.Membrane filtration tekinoroji yakashandiswa zvakanyanya mumishonga, dhayi, chikafu uye maindasitiri ekugadzira muto munyika dzekumadokero dzakabudirira.Iko kushandiswa kwe membrane filtration tekinoroji mukugadzirwa kwemavara echisikigo kunogona kuvandudza goho rekugadzirwa kwemavara echisikigo, kubvisa dhayi dzechipiri uye kusvibiswa kudiki kwema molecular, uye kuderedza mitengo yekugadzira.Pasina kupokana, tekinoroji yemembrane yakaita basa rakakosha mukubatanidza chimiro chemabhizinesi aya muindasitiri yepigment yechisikigo, uye yakashandiswa zvinobudirira mune rimwe bhizinesi rekugadzira pigment.
Mukugadzira pigment maitiro, kunyanya kumvura yekudyisa ine yakaderera yakasimba, kana ichienzaniswa neiyo yakazara filtration nzira, iyo membrane yekuparadzanisa mudziyo uchishandisa iyo cross-flow filtration nzira inoderedza zvakanyanya kuvharika kwemembrane pamusoro nekuda kwekuyambuka-kuyerera kweiyo. zvinhu uye mvura, izvo zvinogona kuvandudza filtration rate.rate.Uye zvakare, iyo membrane mudziyo inogona kuvharirwa panguva imwe chete, uye hapana chikonzero chekumisikidza imwe sterilization uye kusefa maitiro, kuitira kuti uwane chinangwa chekurerutsa maitiro uye kuderedza mutengo.
1. Microfiltration tekinoroji inogona kusefa zvinhu zvisinganyunguriki muzvinyorwa zvepigment zvakasikwa uye tsvina ine huremu hwemamorekuru hunodarika mazana ezviuru, senge starch, cellulose, muriwo gum, macromolecular tannins, macromolecular proteins nezvimwe zvitsvina.
2. Ultrafiltration inoshandiswa pakujekeswa kwemavara anogadzirwa nekuvirisa, panzvimbo yetsika yekujekesa nzira, inogona kunyatsogadzirisa macromolecular suspensions uye mapuroteni, uye inobvumira kujekesa kwepigment kunopinda mukati me membrane uye kupinda mukati me permeate side.
3. Nanofiltration inoshandiswa pakugadzirisa / kuderedza pigment pamhepo yekushisa, kazhinji pamwe chete kana kuti panzvimbo ye evaporators.Munguva yekusefa, mvura uye kumwe kusvibiswa kudiki-morekuru (senge citrinin mumonascus) zvinopfuura nemukati memembrane nepo pigment zvikamu zvinochengetwa uye zvakanangana.
Mumakore achangopfuura, kuvandudza uye kushandiswa kwemavara echisikigo kwakakura nekukurumidza.Zvisinei, kutsvakurudza uye kukura kwemavara echisikigo kuchiri kutarisana nematambudziko akawanda: chiyero chekuchera chemavara echisikigo chakaderera, uye mari yakakwirira;iyo pigment kugadzikana kwakashata, uye inonzwa kune mamiriro ekunze akadai sechiedza uye kupisa;kune marudzi akawanda, uye tsvakurudzo nebudiriro zvakapararira.Nekuvandudzwa nekuvandudzwa kwetekinoroji yekuparadzanisa tekinoroji, zvinotendwa kuti ichaita basa rakakosha mukubviswa kwemavara echisikigo.Mune ramangwana, musanganiswa wemvura membrane yekuparadzanisa tekinoroji uye akasiyana matekinoroji matsva achawedzera kubuda kwemavara echisikigo uye kugadzirisa mhando yechigadzirwa, kuderedza mutengo wekugadzira.
