Production Process Of HFCS Processing Plant

High fructose corn syrup (HFCS) is a sweetener made from corn starch that is processed by glucose isomerase in a HFCS processing plant to convert some of its glucose into fructose. As a sweetener, HFCS is often compared to granulated sugar, but the manufacturing advantages of HFCS over sugar include easier handling and more cost-effectiveness, and the production process at our HFCS processing plant is described below.

In the traditional process, corn is first ground to extract the cornstarch, which is then turned into fructose using an “acid enzyme” process.

Now DELIFOODS has a new technology, we don’t need to use corn to make starch first, our HFCS processing plant can use corn flour to produce High fructose corn syrup.The first step is to dry-mill corn into corn flour, which is then made into high DE glucose syrup, and finally converts part of its glucose to fructose by glucose isomerase to produce HFCS 42.

The production process of DELIFOODS HFCS processing plant is as follows:

 1.Corn flour production process of HFCS processing plant

Corn flour production from corn is not the same as regular corn flour processing.

After the corn is washed, the corn germ is first separated, and then the corn husk is peeled to obtain corn flour for milling. After grinding and sieving several times, high-quality corn flour is obtained, which is used to make glucose syrup.

2.Corn flour pulping process of HFCS processing plant

Mix cornmeal and water to get the correct density slurry. Then amylase is added and kept for a certain time so that the cornmeal absorbs enough water.

3.Liquefaction process of HFCS processing plant

The liquefaction process converts the starch contained in cornmeal into liquid dextrin. The material will be sprayed at high temperatures through the jet cooker. With the help of amylase and steam, starch is quickly converted into liquid dextrin.

4.Deproteinization process of HFCS processing plant

The deproteinization process is to separate the corn gluten and other solid impurities from the liquid dextrin through a filter press. The liquid dextrin will be pumped to the next process and the zein will remain for sale. .

The by-product corn gluten (feed grade) is a high-grade protein additive for making animal feed.

5.Saccharification process of HFCS processing plant

The saccharification process is the conversion of liquid dextrin into glucose syrup with the desired DE value by means of glucoamylase in the tank. The process should run for several hours at a specific temperature. It takes longer to make high DE glucose syrup.

6.Decolorization process of glucose syrup in HFCS processing plant

The decolorization process is to remove the color of glucose syrup through activated carbon. The glucose syrup with the desired DE is pumped from the saccharification tank into the decolorization tank, where it is mixed with activated carbon at the appropriate temperature.

7.HFCS processing plant glucose syrup decarbonization process

The decarbonization process is to separate the activated carbon from the glucose syrup through a filter press to obtain a transparent glucose syrup.

The glucose syrup will flow into the tank and transfer tank for the next step. Activated carbon will be left behind.

8.Glucose syrup ion exchange process in HFCS processing plant

The ion exchange process uses resin to remove tiny foreign matter and odor to obtain high-quality pure glucose syrup.

The resin needs acid-base washing and regeneration after working for several days.

9.HFCS processing plant glucose syrup evaporation process

The evaporation process is to evaporate the water in the glucose syrup, so that the DS of the glucose syrup reaches the requirement before isomerization (45%).

10.Isomerization process of HFCS processing plant

The isomerization process converts glucose syrup into fructose syrup with the help of isomerase. Glucose is converted into fructose syrup with a content of 42%.

11.HFCS processing plant fructose syrup decolorization process

The decolorization process is to remove the color of fructose syrup through activated carbon. The fructose syrup will be pumped into a decolorizing tank where it will be mixed with activated charcoal at the right temperature.

12.HFCS processing plant high fructose syrup decarbonization process

The decarbonization process is to separate the activated carbon from the fructose syrup through a filter press to obtain a clear fructose syrup.

13.HFCS processing plant HFCSion exchange process

The ion exchange process uses resin to remove tiny foreign matter and odor to obtain high-quality pure fructose syrup.

The resin needs acid-base washing and regeneration after working for several days.

14.HFCS processing plant fructose syrup evaporation process

The evaporation process is to evaporate the water in the high fructose syrup, so that the DS of the high fructose syrup meets the requirements (DS is about 71%).

15.Storage of finished products in HFCS processing plants

The fructose syrup that reaches the desired DS during the evaporation process will be pumped into the final product storage tank for storage.

The finished tank maintains the purity of the high fructose syrup prior to shipping.
