[Refining system] [Brief Process]

[Our Other Activities and Project Services]        

.

DEXTROSE MONOHYDRATE :
The starch slury is adjusted to 6.0 Ph. and treated with (alpha) Amylase enzyme and jet cooked, liquified to achieve liquid syrup having no starch. The syrup is then treated with activated carbon for decolourisation and deashing is done to remove ash from syrup.

Deashed Syrup is concentrated in evaporation system to a concentration of 76 % DS cooled and crystallized in batch or continuous crystallizer.

Crystallized mececutes are centrifiged to get wet DMH crystalls which is further dried in Flash dryer / Rotary dryer or Fluid bed dryer where as Hydrol is recycled back after refining to recovered maximum DMH. Dry powder is sieved and packed.

The DMH has industrial application in syrup base as pharma product and fermentation process for alcohol and medicenes.

    The DMH crystall wet is deasolved, refined, evaporated, hot crystalled, centrifuged, dried and sieved to get Anhydrous form of Dextrose to be used in IV fluid for Glucose saline which is used in medicene.

  • LIQUID GLUCOSE :
    The acidified starch slurry to be treated at 145oC, cooled neutralised and floculation is done to remove fats.
    The syrup is treated with activated carbon and filter aid to remove colour and demineralised to remove ash content.
    The demineralised syrup is then concentrated to a desired concentration as per market demand up to 86% DS.
    The 86% DS syrup is used in confectionery and other sweetening agent.

  • MALTO DEXTRIN :
    Starch slurry of 0.4 % DS protein and 0.05 % DS oil max will be collected in a Tank from time to time and adjust Ph. to 6.00 before adding liquification enzyme ( Alpha amylose or equivalant). After through mixing, slurry is fed to jet cooker, followed by retention and liquification coil at a temperature of 110oC and see the hydrolysis is complete and De is controlled to 20 or 25 De as may be required. Excess enzyme if any may be killed by acidifying it so that no further hydrolysis may occur. During these process please check that there is no sign of starch being unhydrolysed. Then these slurry is filtered off in filter press to remove suspended solids of protein and other matters with the help of filter aid and carbon. Once again, the slurry or clear liquid may be treated with carbon & filter aid to decolourise the syrup. Then cooled to pass through demineraliser to remove Ash content of the juice and concentrated in multi effect evaporator to a level of 60 % - 65 % DS and spray dried sieved and packed.

  • USAGE : It is used in baby food and also in confectionery like chocolets for low calory brand. Syrup is used in low calory soft drinks as sweetners.
