Doing Company has a professional starch syrup equipment design and making team, can provide you good quality set of starch syrup equipments. If you want to know how to make glucose syrup from starch or you want know the technology process of glucose syrup making from starch, following is the answer:

1. Starch quality check and transfer:
The starch water contain should be less than 14%, and starch not weird. Next transfer the starch to mixing tank.

2. Glucose syrup mixing and liquefaction section:
Mixing the starch with clean water, make the concentration to 18Be, PH value get to 5.6-6.0. put into the α-enzyme, then deliver the liquid to jet cooker with steam heating temperature 100-108℃ to make liquefied process.

3. Protein in starch liquid filtering process:
The starch liquid is delivery to plate frame filter press machine to remove the protein then the separated proteins can be washed, dried and crushed to packed into the warehouse changed to animal feed. This increase the add-value of your plant.

4. Saccharification section:
This section use the saccharifying tank, adjust the liquid temperature to 60℃, PH value 4.2-4.8, put saccharify enzyme, then keep 36-50 hours.

5. First decoloring section:
Adding activated carbon to the liquid, this part time need 0.5 ~ 1 hour, then send the liquid to plate frame filter press machine for decoloring then can get bright and pure glucose syrup, this time the transmittance of the solutions should more than 75%.

6. First Ion exchange:
When the solutions temperature is decreased about 42℃, then to ion exchange column. The conductivity value of the final liquid is less than 20ppm.

7. Pre-concentration section:
After ion exchange process, pre-concentration the glucose syrup liquid to 45Bx.

8. Second decoloring:
Also use activated carbon to make decoloring for glucose syrup making, but this time the transmittance should be 95%.

9. Second ion exchange:
This time should decrease the temperature to 30-35℃, then transfer to ion exchange system, then conductivity of the glucose syrup is more than 95%.

10: Glucose syrup evaporation process:
In this section, evaporator usually used three-effect type.
