Machine for making fructose syrup
 

Below is Doing Company production process for making fructose syrup:

1. Corn starch mixing process:
Mixing the starch and water to get the right density slurry. Then add the α-enzyme and keep the temperature for particular time to make corn powder absorbing enough water for starch dextrinization. Requests the mixing tank in this process for making fructose syrup

2. Liquefaction process:
This liquefaction process is used to convert the starch into liquid dextrin. The starch slurry will be sprayed at high temperature by jet cooker. With the add of amylase and steam, the starch will be converted into liquid dextrin fastly.

Glucose syrup production process

3. Deproteinization for making fructose syrup:
The deproteinization process function is separate the starch protein and other solid impurity from liquid dextrin by filter press, usually the plate frame filter press machine, then the liquid dextrin will be pumped to next process, the corn protein can be left for sale, it's a good product for animal feeding.

4. Saccharification:
Saccharification process can convert the liquid dextrin into required DE value in the saccharification tank. This process should be run under specific temperature for some hours. For making high DE glucose syrup, it will cost more time. The saccharification tank is requested in this process for making fructose syrup.

5. Decolorization process:
The decolorization process is removing the color of the glucose syrup by activated carbon adsorption principle. The glucose syrup which reached required DE  will be pumped from saccharification tank into the decolorization tank, mixed with activated carbon at proper temperature.

6. Decarburization process:
The decarburization process is used to separating the activated carbon from the glucose syrup by filter press to get clear glucose syrup. The glucose syrup will flow into the slot and delivery by transfer tank to next step for making fructose syrup, the waste activated carbon will be left.

Ion exchange working principle

7. Ion exchange process:
The Ion exchange process is using the resin to remove the tiny foreign items and bad odor to get high quality pure glucose syrup for making high purity glucose syrup. The resin need regeneration by acid and alkali washing after working for some days.

8. Evaporation process:
The evaporation process is aimed to evaporate the excedd water inside the glucose syrup to increase the DS of glucose syrup to the requirement (45%) before isomerisation. We will suggest you the most suitable syrup evaporator for you to making fructose syrup.

9. Isomerism process in fructose syrup production machine
The isomerism process can convert the glucose into fructose syrup with the used of isomerase. The glucose is converted into with 42% content of fructose syrup. This process and below process section is special for making fructose syrup, if you just want to get the glucose, then no need these section.

After evaporation process, the DS of fructose syrup reach to the requirement (DS around 71%).

During process for making fructose syrup, the first enzyme added is alpha-amylase which breaks the long chains down into shorter sugar chains – oligosaccharides. Glucoamylase is mixed in and converts them to glucose; the resulting solution is filtered to remove protein, then using activated carbon, and then demineralized using ion-exchange resins. The purified solution is then run over immobilized xylose isomerase, which turns the liquid to 50–52% glucose with some unconverted oligosaccharides, and 42% fructose (HFCS 42), and again demineralized and again purified using activated carbon. Some is processed into HFCS 90 by liquid chromatography, then mixed with HFCS 42 to form HFCS 55. Among is the totally introduction of our method and machine for making fructose syrup.
