In the contemporary process, corn is milled to produce corn starch and an "acid-enzyme" process is used in which the corn starch solution is acidified to begin breaking up the existing carbohydrates, and then enzymes are added to further metabolize the starch and convert glucose to fructose.
During the high fructose corn syrup production plant process, 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 sugars 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.
On the following use the starch for example to introduce our high fructose corn syrup production plant. High fructose corn syrup production process mainly include three section, that is starch liquefaction, saccharification and isomerism process. The detail manufacturing process flowchart as below(you can click high fructose corn syrup production equipment to learn the complete production process):

Then below is the main fructose syrup production machine and its functions in various parts:
Mixing the starch and water to get the right density slurry, add certain enzyme, adjust the PH value and temperature to get the starch milk. Now our advanced technology for fructose syrup production machine also can use the corn/ rice powder as raw material directly. This type fructose syrup production machine used in the mixing process.
2. Liquefaction tank & ejector:
Used in the liquefaction process can convert the starch into liquid dextrin, the liquefaction tank include the laminar tank, maintaining tank and neutralization tank. The liquid during fructose syrup production pumped by the ejector.
3. Plate frame filter press machine:
On the before introduction, you can know that this machine is used in two sections for the fructose syrup production, not only the deproteinization, but also the decolorization process. It's an important machine for the syrup purity. The deproteinization process function is used to separate the protein and other solid impurity from liquid dextrin, with automatic mechanical extrusion method.
And the decolorization process also adopt this plate frame filter press machine, according to the activated carbon adsorption principle. The decolorization & decarbaurization normal sequence is the first decolorization-the first decarburization-The second decolorization-the second decarburization.
4. Saccharification tank:
After liquefaction, the pH value is reduced to between 4.2-4.5, after the solution temperature is cooled to 60 ℃, added the glucomylase (Novo’s AMG 300L) immediately. The reaction time for saccharification is usually between 24-48 hour depending on enzyme reaction speed. Glucoamylase releases single glucose units from the ends of dextrin molecule, syrups of 95% glucose or higher are manufactured by the saccharification tank, important for the fructose syrup production.

5. Ion exchange column:
Ion exchange as one of the fructose syrup production machine, can remove the Ca2+ and Mg2+ etc, and the negative ions, pure the syrup, the resin need regeneration by acid and alkali washing after working for some days.
6. Isomerism system:
The isomerism system can make the purified glucose solution isomerized by a reactor containing immobilized isomerase to obtain fructose syrup with 42% fructose content. It's honor to tell you that the isomerase we are using is a kind of immobilized enzyme. Converted from soluble state into immobilized state, the stability of isomerism will be increased significantly and it can be uses repeatedly in the high fructose corn syrup produced. This immobilized enzyme used in food processing make food free of enzyme after production, so there is no need to adopt the way of heat treatment to make enzyme inactivated, which can help improving the quality of food as well as economic benefits.
Evaporation process for fructose syrup production is aimed to remove the excess moisture from the syrup liquid. We will suggest you the most suitable type syrup evaporator as your production requests.
Compared with other syrup equipment manufacturers, our fructose syrup production machine is easy to handle, highly dependable, completely automation control with smart design. Under the production, our fructose syrup production machine can achieve no waste water discharge, full sealing process, use the special enzyme for starch hydrolysis to converts glucose, then transfer into fructose, this is the most advanced and highest efficiency fructose syrup production method. And our company is responsible for the your fructose production machine design, installation, commissioning and training the operator, give you perfect service.
The features of our company's high fructose corn syrup production plant and technology is that we can use corn as raw material to make high fructose corn syrup directly, no need to make starch.
