Elintarvikelaatuisten hartsien esik\u00e4sittely- ja regenerointimenetelm\u00e4.<\/span><\/span><\/span><\/h2>\n

Ioninvaihtohartsien tuotantoprosessissa mukana tulee aina pieni m\u00e4\u00e4r\u00e4 orgaanisia matalapolymeerej\u00e4 ja ep\u00e4orgaanisia ep\u00e4puhtauksia. Lis\u00e4ksi <\/span><\/span><\/span>kuljetuksen ja t\u00e4yt\u00f6n aikana tuotteisiin voi tulla ep\u00e4puhtauksia. N\u00e4m\u00e4 ep\u00e4puhtaudet vapautuvat k\u00e4yt\u00f6n alussa ja vaikuttavat sitten tuotetun veden ja tuotteiden laatuun. Siksi kaikki uudet hartsit on esik\u00e4sitelt\u00e4v\u00e4 ennen k\u00e4ytt\u00f6\u00e4. <\/span><\/span>Ioninvaihtohartsit<\/span><\/span><\/a> on esik\u00e4sitelt\u00e4v\u00e4 ep\u00e4puhtauksien poistamiseksi ennen k\u00e4ytt\u00f6\u00e4 sokeriliemen vakaan laadun varmistamiseksi. Ennen hartsien t\u00e4ytt\u00e4mist\u00e4 laitteisiin <\/span><\/span><\/span>kaikki ioninvaihtohartsikolonnit, putket ja venttiilit on pest\u00e4v\u00e4 vedell\u00e4, kunnes ulostuleva vesi on puhdasta. Varmista, ettei vuotoja ole, ja t\u00e4yt\u00e4 sitten vaihtokolonni vedell\u00e4 1\/4 korkeuteen asti. T\u00e4yt\u00e4 sitten hartsit kolonniin, sy\u00f6t\u00e4 vesi sis\u00e4\u00e4n alhaalta ja poista vesi ylh\u00e4\u00e4lt\u00e4 hartsien vastavirtahuuhteluun. Huuhtele, kunnes vesi on puhdasta ja siin\u00e4 ei ole en\u00e4\u00e4 pieni\u00e4 hiukkasia. (Jotta v\u00e4ltet\u00e4\u00e4n suurten hiukkasten kokoisen hartsin ulostulo, kiinnit\u00e4 huomiota virtausnopeuden s\u00e4\u00e4t\u00f6\u00f6n) <\/span><\/span><\/span>

\n. Lis\u00e4\u00e4 hartsi vaihtokolonniin ja huuhtele hartsi pehmennysvedell\u00e4, kunnes ulostuleva vesi on puhdasta. Liota hartsia 4\u20138 tuntia 8\u201310 % NaCL:lla, joka on kaksinkertainen hartsitilavuus, ja pese sitten pehmennysvedell\u00e4, kunnes ulostuleva vesi on puhdasta. <\/span><\/span><\/span>

Hartsin kontaminaation syyt ja talteenottomenetelm\u00e4<\/span><\/span><\/b><\/span><\/span><\/p>\n

(1) Saastumisen syyt<\/span><\/span><\/span><\/span><\/p>\n

Koska k\u00e4sitelty liuos sis\u00e4lt\u00e4\u00e4 orgaanisia aineita, rautaa, piit\u00e4, mikro-organismeja, kolloideja jne., n\u00e4it\u00e4 aineita ei voida poistaa kokonaan aktiivihiilen suodatusprosessin aikana. Ioninvaihdon prosessissa n\u00e4m\u00e4 aineet adsorboituvat anionihartsin matriisiin vetysidosten, ionisidosten, kovalenttisten sidosten ja VDW:n vaikutuksesta. Yleens\u00e4 15\u201330 k\u00e4ytt\u00f6jakson j\u00e4lkeen orgaanisten aineiden kertyminen vaikuttaa hartsien vaihtokykyyn, heikent\u00e4\u00e4 sokerin laatua ja lis\u00e4\u00e4 pesuveden tarvetta. T\u00e4t\u00e4 kutsutaan orgaaniseksi kontaminaatioksi.<\/span><\/span><\/span><\/span><\/p>\n

(2) Palautusmenetelm\u00e4<\/span><\/span><\/span><\/span><\/p>\n

(2.1) Huuhtele kontaminoituneita hartseja vastavirtahuuhteella, kunnes ulostuleva vesi on puhdasta.<\/span><\/span><\/span><\/span><\/p>\n

(2.2) Kationihartsi, jossa on yleens\u00e4 rautakontaminaatiota, liota hartsia 4\u20138 tuntia 10\u201315 %:n HCl-liuoksella, joka on kaksinkertainen hartsin tilavuuteen verrattuna, ja pese sitten vedell\u00e4.<\/span><\/span><\/span><\/span><\/p>\n

(2.3) Anionihartsi, jossa on yleens\u00e4 orgaanista kontaminaatiota, liota hartsia 4\u20135 %:n HCl-liuoksella, joka vastaa kahta hartsitilavuutta, 2\u20134 tuntia ja pese sitten vedell\u00e4. Liota hartsia 10 %:n NaCl-liuoksella, joka vastaa kolmea hartsitilavuutta. L\u00e4mp\u00f6tilan on oltava 40 \u2103 ja virtausnopeuden 4 m\/h. Kun olet k\u00e4ytt\u00e4nyt viimeisenkin tilavuuden, anna liota 12 tuntia ja pese sitten deionisoidulla vedell\u00e4. Tarkkaile veden v\u00e4ri\u00e4 ja p\u00e4\u00e4t\u00e4, onko vesi riitt\u00e4v\u00e4n puhdasta. P\u00e4\u00e4t\u00e4 sitten, onko k\u00e4sittely tarpeen.<\/span><\/span><\/span><\/span><\/p>\n

(2.4) kaksoisregeneroinnin j\u00e4lkeen se voi alkaa toimia.<\/span><\/span><\/span><\/span><\/p>\n

4. Hartsin s\u00e4ilytys<\/span><\/span><\/b><\/span><\/span><\/p>\n

K\u00e4ytt\u00e4m\u00e4tt\u00f6m\u00e4t hartsit tulee s\u00e4ilytt\u00e4\u00e4 suljetussa pussissa, \u00e4l\u00e4 altista hartsia ilmalle ja s\u00e4ilyt\u00e4 sit\u00e4 0\u201340 \u2103 <\/span><\/span><\/span><\/span>:n l\u00e4mp\u00f6tilassa <\/span><\/span><\/span><\/span>. Jos hartsi lakkaa toimimasta jonkin aikaa k\u00e4yt\u00f6n aikana, v\u00e4lt\u00e4 seuraavia olosuhteita:<\/span><\/span><\/span><\/span><\/p>\n

(1) Est\u00e4 kuivuminen t\u00e4ytt\u00e4m\u00e4ll\u00e4 laite t\u00e4yteen vett\u00e4. Jos vesi on poistettava, pid\u00e4 laite suljettuna, jotta hartsin sis\u00e4inen kosteuspitoisuus ei haihdu.<\/span><\/span><\/span><\/span><\/p>\n

(2) Est\u00e4 j\u00e4\u00e4tyminen. Jos l\u00e4mp\u00f6tila on alle 0 \u2103, laitteeseen tulee lis\u00e4t\u00e4 suolaliuosta hartsin imeytt\u00e4miseksi.<\/span><\/span><\/span><\/span><\/p>\n

(3) Bakteerien kasvun est\u00e4minen. Jos hartsia s\u00e4ilytet\u00e4\u00e4n pitk\u00e4\u00e4n laitteissa, se kasvattaa mikro-organismeja, kuten levi\u00e4 ja bakteereja, jotka aiheuttavat hartsin saastumista. Ennaltaehk\u00e4isev\u00e4 toimenpide on hartsin t\u00e4ydellinen takaisinpesu sen j\u00e4lkeen, kun hartsi on menett\u00e4nyt kykyns\u00e4 poistaa ep\u00e4puhtauksia, ja hartsin liottaminen regeneroinnin j\u00e4lkeen.<\/span><\/span><\/span><\/span><\/p>\n

Huomautus: Ennen elintarviketeollisuuden hartsin esik\u00e4sittely\u00e4 valmista pehmennysvesi k\u00e4ytt\u00e4m\u00e4ll\u00e4 kationipetihartsia ja anionipetihartsia. S\u00e4ilyt\u00e4 pehmennysvesi vesis\u00e4ili\u00f6ss\u00e4 (jos sit\u00e4 ei ole tarpeeksi, tee lis\u00e4\u00e4). Pehmennysvesi valmistetaan k\u00e4ytett\u00e4v\u00e4ksi hartsin vastapesuun esik\u00e4sittelyprosessin aikana laimean hapon ja laimean em\u00e4ksen valmistamiseksi ja valkoisen saostuman muodostumisen v\u00e4ltt\u00e4miseksi, koska veden pito vaikuttaa hartsin regeneratiiviseen vaikutukseen my\u00f6hemm\u00e4ll\u00e4 k\u00e4ytt\u00f6vaiheella.<\/span><\/span><\/span><\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
