M\u00e9thode de pr\u00e9traitement et de r\u00e9g\u00e9n\u00e9ration des r\u00e9sines de qualit\u00e9 alimentaire.<\/span><\/span><\/span><\/h2>\n

Lors de la production de r\u00e9sines \u00e9changeuses d’ions, de faibles quantit\u00e9s de polym\u00e8res organiques et d’impuret\u00e9s inorganiques sont in\u00e9vitablement pr\u00e9sentes. Des <\/span><\/span><\/span>impuret\u00e9s peuvent \u00e9galement se d\u00e9poser sur les produits lors du transport et du conditionnement. Ces impuret\u00e9s, lib\u00e9r\u00e9es d\u00e8s la premi\u00e8re utilisation, affectent la qualit\u00e9 de l’eau et des produits finis. C’est pourquoi toutes les r\u00e9sines neuves doivent subir un pr\u00e9traitement. Ce pr\u00e9traitement permet d’\u00e9liminer les impuret\u00e9s et de garantir la stabilit\u00e9 de la qualit\u00e9 de la liqueur de sucre. Avant d’introduire les r\u00e9sines dans l’\u00e9quipement, les colonnes d’\u00e9change d’ions, ainsi que les tuyauteries et vannes, doivent \u00eatre rinc\u00e9es \u00e0 l’eau jusqu’\u00e0 ce que <\/span><\/span>l’<\/span><\/span><\/a> eau <\/span><\/span><\/span>de sortie soit limpide. En cas de fuite, remplir la colonne d’\u00e9change d’ions jusqu’au quart de sa hauteur, puis y introduire les r\u00e9sines. L’eau est introduite par le bas et \u00e9vacu\u00e9e par le haut pour le r\u00e9trolavage des r\u00e9sines. Rincer abondamment jusqu’\u00e0 ce que l’eau soit parfaitement claire et exempte de particules. (Pour \u00e9viter la remont\u00e9e de particules de r\u00e9sine de grande taille, veuillez ajuster le d\u00e9bit.) <\/span><\/span><\/span>
\n1. Remplissage et pr\u00e9traitement des r\u00e9sines<\/span><\/span><\/strong><\/span>
\n (1) Chargement de la colonne de r\u00e9sine <\/span><\/span><\/span>
\n: Introduire la r\u00e9sine dans la colonne d’\u00e9change et la rincer \u00e0 contre-courant avec de l’eau adoucie jusqu’\u00e0 ce que l’eau de sortie soit propre. Faire tremper la r\u00e9sine dans une solution de NaCl \u00e0 8-10 % (deux fois son volume) pendant 4 \u00e0 8 heures, puis rincer \u00e0 l’eau adoucie jusqu’\u00e0 ce que l’eau de sortie soit propre. <\/span><\/span><\/span>
\n(2) Pr\u00e9traitement de la r\u00e9sine cationique <\/span><\/span><\/span>
\n(2.1) Introduire une solution de HCl \u00e0 4 % dans la colonne d’\u00e9change \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h. Lorsque le pH atteint 1, poursuivre l’injection pendant 15 minutes, puis arr\u00eater. Apr\u00e8s un trempage de 4 \u00e0 8 heures, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucie jusqu’\u00e0 ce que le pH atteigne environ 3. <\/span><\/span><\/span>
\n(2.2) Introduire une solution de NaOH \u00e0 4 % dans la colonne \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h. Lorsque le pH atteint <\/span><\/span><\/span>2 <\/span><\/span><\/span>, poursuivre l’injection pendant 15 minutes, puis arr\u00eater. Apr\u00e8s trempage de la r\u00e9sine pendant 4 \u00e0 8 h, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucie jusqu’\u00e0 ce que le pH atteigne environ 10. <\/span><\/span><\/span>
\n(2.3) Introduire une solution d’HCl \u00e0 4 % dans la colonne \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h. Lorsque le pH atteint <\/span><\/span><\/span>1, poursuivre l’injection pendant 15 min, puis arr\u00eater. Apr\u00e8s trempage de la r\u00e9sine pendant 4 \u00e0 8 h, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucie jusqu’\u00e0 ce que le pH atteigne environ 3. Le pr\u00e9traitement de la r\u00e9sine cationique est alors <\/span><\/span><\/span>termin\u00e9\u00a0; la r\u00e9g\u00e9n\u00e9ration peut \u00eatre effectu\u00e9e normalement. (Utiliser deux fois le <\/span><\/span><\/span>volume normal d’agent r\u00e9g\u00e9n\u00e9rant pour la premi\u00e8re r\u00e9g\u00e9n\u00e9ration). <\/span><\/span><\/span>
\n(3) Pr\u00e9traitement de la r\u00e9sine anionique <\/span><\/span><\/span>
\n(3.1) Introduire une solution de NaOH \u00e0 4 % dans la colonne \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h. Lorsque le pH <\/span><\/span><\/span>atteint 14, poursuivre l’injection pendant 15 min, puis arr\u00eater. Apr\u00e8s un trempage de la r\u00e9sine pendant 4 \u00e0 8 h, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucie jusqu’\u00e0 ce que le pH atteigne environ 10. <\/span><\/span><\/span>
\n(3.2) Introduire une solution d’HCl \u00e0 4 % dans la colonne \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h. Lorsque le pH atteint <\/span><\/span><\/span>1, poursuivre l’injection pendant 15 min, puis arr\u00eater. Apr\u00e8s un trempage de la r\u00e9sine pendant 4 \u00e0 8 h, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucie jusqu’\u00e0 ce que le pH atteigne environ 3. <\/span><\/span><\/span>
\n(3.3) Introduire une solution de NaOH \u00e0 4 % dans la colonne \u00e0 un d\u00e9bit de 1,5 \u00e0 2,0 BV\/h.<\/span><\/span><\/span>14. Poursuivre le remplissage pendant 15 min, puis arr\u00eater. Apr\u00e8s trempage de la r\u00e9sine pendant 4 \u00e0 8 h, rincer <\/span><\/span><\/span>\u00e0 l’eau adoucissante jusqu’\u00e0 ce que le pH atteigne environ 10. Le pr\u00e9traitement de l’anion \u00e9tant <\/span><\/span><\/span>termin\u00e9, la r\u00e9g\u00e9n\u00e9ration peut \u00eatre effectu\u00e9e normalement. (Utiliser deux fois le <\/span><\/span><\/span>volume normal d’agent r\u00e9g\u00e9n\u00e9rant pour la premi\u00e8re r\u00e9g\u00e9n\u00e9ration.) <\/span><\/span><\/span>

Causes de la contamination de la r\u00e9sine et m\u00e9thode de r\u00e9cup\u00e9ration<\/span><\/span><\/b><\/span><\/span><\/p>\n

(1) Causes de la contamination<\/span><\/span><\/span><\/span><\/p>\n

\u00c9tant donn\u00e9 que la solution trait\u00e9e contient des mati\u00e8res organiques, du fer, du silicium, des micro-organismes, des collo\u00efdes, etc., ces substances ne peuvent \u00eatre compl\u00e8tement \u00e9limin\u00e9es lors du processus de filtration par charbon actif. Lors du processus d’\u00e9change d’ions, ces substances s’adsorbent \u00e0 la matrice de la r\u00e9sine anionique par liaisons hydrog\u00e8ne, liaisons ioniques, liaisons covalentes et forces de van der Waals. G\u00e9n\u00e9ralement, apr\u00e8s 15 \u00e0 30 cycles de fonctionnement, l’accumulation de mati\u00e8res organiques affecte la capacit\u00e9 d’\u00e9change des r\u00e9sines, ce qui entra\u00eene une mauvaise qualit\u00e9 du sucre et une augmentation des co\u00fbts de lavage. C’est ce que l’on appelle la contamination organique.<\/span><\/span><\/span><\/span><\/p>\n

(2) M\u00e9thode de r\u00e9cup\u00e9ration<\/span><\/span><\/span><\/span><\/p>\n

(2.1) laver \u00e0 contre-courant les r\u00e9sines contamin\u00e9es jusqu’\u00e0 ce que l’eau de sortie soit propre.<\/span><\/span><\/span><\/span><\/p>\n

(2.2) La r\u00e9sine cationique est g\u00e9n\u00e9ralement contamin\u00e9e par du fer, utiliser 10 \u00e0 15 % d’HCl deux fois le volume de r\u00e9sine pour tremper la r\u00e9sine pendant 4 \u00e0 8 heures, puis laver \u00e0 l’eau pour la nettoyer.<\/span><\/span><\/span><\/span><\/p>\n

(2.3) La r\u00e9sine anionique pr\u00e9sente g\u00e9n\u00e9ralement une contamination organique. Utiliser une solution d’HCl \u00e0 4-5 % dont le volume est deux fois celui de la r\u00e9sine, faire tremper pendant 2 \u00e0 4 heures, puis rincer \u00e0 l’eau. Faire ensuite passer une solution compos\u00e9e de 10 % de NaCl et de 3-4 % de NaOH dont le volume est trois fois celui de la r\u00e9sine, \u00e0 une temp\u00e9rature de 40 \u00b0C et un d\u00e9bit de 4 m\u00b3\/h. Apr\u00e8s avoir fait passer le dernier volume de r\u00e9sine, laisser tremper pendant 12 heures, puis rincer \u00e0 l’eau d\u00e9min\u00e9ralis\u00e9e. Observer la couleur de l’eau pour v\u00e9rifier sa propret\u00e9 et d\u00e9cider si un nouveau traitement est n\u00e9cessaire.<\/span><\/span><\/span><\/span><\/p>\n

(2.4) apr\u00e8s une double r\u00e9g\u00e9n\u00e9ration, il pourrait commencer \u00e0 fonctionner.<\/span><\/span><\/span><\/span><\/p>\n

4. Stockage de la r\u00e9sine<\/span><\/span><\/b><\/span><\/span><\/p>\n

Les r\u00e9sines non utilis\u00e9es doivent \u00eatre conserv\u00e9es dans un sachet herm\u00e9tique, \u00e0 l’abri de l’air, et \u00e0 une temp\u00e9rature comprise entre 0 <\/span><\/span><\/span><\/span>et <\/span><\/span><\/span><\/span>40 \u00b0C. Si la r\u00e9sine est bri\u00e8vement interrompue pendant son fonctionnement, il convient d’\u00e9viter les conditions suivantes\u00a0:<\/span><\/span><\/span><\/span><\/p>\n

(1) Pour \u00e9viter la d\u00e9shydratation, remplissez l’\u00e9quipement d’eau. Si vous devez vider l’eau, assurez-vous que l’\u00e9quipement est bien scell\u00e9 pour \u00e9viter la perte d’humidit\u00e9 interne de la r\u00e9sine.<\/span><\/span><\/span><\/span><\/p>\n

(2) Pour \u00e9viter le gel, si la temp\u00e9rature est inf\u00e9rieure \u00e0 0\u2103, il faut remplir l’\u00e9quipement de solution saline pour tremper la r\u00e9sine.<\/span><\/span><\/span><\/span><\/p>\n

(3) Emp\u00eacher la croissance des bact\u00e9ries, si la r\u00e9sine est conserv\u00e9e longtemps dans l’\u00e9quipement, elle d\u00e9veloppera des micro-organismes comme des algues et des bact\u00e9ries, provoquant ainsi la contamination de la r\u00e9sine. La mesure pr\u00e9ventive consiste \u00e0 laver compl\u00e8tement la r\u00e9sine \u00e0 contre-courant apr\u00e8s que celle-ci ait perdu sa capacit\u00e9 \u00e0 \u00e9liminer les impuret\u00e9s en suspension, puis \u00e0 tremper la r\u00e9sine apr\u00e8s r\u00e9g\u00e9n\u00e9ration.<\/span><\/span><\/span><\/span><\/p>\n

Remarque : Avant le pr\u00e9traitement de la r\u00e9sine pour l’industrie alimentaire, pr\u00e9parez de l’eau adoucissante \u00e0 l’aide d’un ensemble de r\u00e9sine \u00e0 lit cationique et de r\u00e9sine \u00e0 lit anionique. Conservez l’eau adoucissante dans un r\u00e9cipient (pr\u00e9parez-en \u00e0 nouveau si n\u00e9cessaire). Cette eau adoucissante sera utilis\u00e9e ult\u00e9rieurement pour le lavage \u00e0 contre-courant de la r\u00e9sine lors du pr\u00e9traitement. Pr\u00e9parez une solution acide dilu\u00e9e et une solution alcaline dilu\u00e9e afin d’\u00e9viter la formation de d\u00e9p\u00f4ts blancs, car la duret\u00e9 de l’eau affecterait l’effet de r\u00e9g\u00e9n\u00e9ration de la r\u00e9sine lors des op\u00e9rations ult\u00e9rieures.<\/span><\/span><\/span><\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
