LIQUEFACTION PROCESS
Pumping starch slurry into the mixing tank, there could be some brown floater appearing on the surface of mixing tank, which is likely to be caused by high protein content. It will cause high dosage of activated carbon, increasing the load of ion exchange, and reducing the service life of ion-exchange resin, so we must ensure that the starch milk protein content is below 0.5%. In order to make full use of the mother liquor, the part starch milk can be recycled in the mixing slurry process, and the normal return amount can reach up to 2/3. The overused in corn syrup plant will affect the quality. Average concentration is 35% - 36%. Mixing temperature is 29 ℃ -34 ℃ . Then pumping starch slurry into the ejector.
Large and medium-sized corn syrup plant enterprises flow rate is 25-40 m3 / h; steam pressure is 0.4 Mpa; liquefied liquid temperature is 99 ℃ . After that entering the laminar flow tank for heat preservation of 60 minutes, and then into maintaining tank. Put the liquefied liquid into the second ejector. The steam injection pressure control is 0.2 Mpa; the temperature control is 130℃ to 134.6℃. Liquefied liquid will come into the high temperature maintain tank and then secondary flash cooling tank. The liquid temperature lower 64℃ to 60℃ to neutralize, then coming into the neutralization tank, adjusting the pH value to 4.4-4.5 for preparing glycosylated in corn syrup plant.
DECARBOM PROCESS
Liquid dextrin which has been through high temperature injection shall move into filter press for mechanical extrusion in corn syrup plant.The deproteinization process will separate the protein and other solid impurities from liquid dextrin by filter press. After that, the liquid dextrin will be pumped to next process, the protein cake will be left for sale.
SACCHARIFICATION PROCESS
The liquefied liquid (solid content of 30% -35%) is pumped to the saccharification tank and cooled to 60°C. Adding acid to adjust the pH to around 4.5. The brix is 31-32Bx; the adjusted concentration is 34.67% -35.6%; adding the saccharification enzyme is equivalent to 0.45-0.58L / ton dry starch. The liquefied liquid DE value is 28.85% -31.53%, the pumping time is 4-6 hours for one tank. Each tank of saccharification time is 50 hours for corn syrup plant operation. The DE value is about 95-97 when finished. The saccharification liquid is pumped into the pre-coated perlite drum filter to separate protein, and then entering the third time injectors for enzyme deactivation after saccharification. The third injection temperature is about 99℃; the injection pressure is 0.39Mpa; and the saccharification liquid yield is about 98% -105%.
DECOLORIZATION & DECARBURIZATION
The normal sequence about this part in corn syrup plant is:The first decolorization→the first decarburization→The second decolorization→the second decarburization.
The saccharification liquid will be pumped into a decolorization tank, adding the waste activated carbon of the second plate frame filter pressing then killing enzyme and decolorization for 30 minutes. Then pumping the discolored syrup liquid into the first plate frame, the activated carbon will be filter out. Pumping the first discolored syrup liquid into the second decolorization tank, adding new activated carbon, decolorization for 30 minutes. The second decolored syrup liquid is subjected to plate and frame filtration, and then it will be pumped into the ion exchange system storage tank through the plate heat exchanger in corn syrup plant.
