High fructose corn syrup manufacturing process equipment

Fructose syrup is a kind of starch sugar which is converted from refined corn starch by enzymatic method. The main ingredient is fructose and glucose. Its main feature is: cleaning sweet, refreshing fruit fragrance, colorless transparent, use convenient.

Following is the high fructose corn syrup manufacturing process introduction:

1. Thick liquid mixing:as the features of starch liquidation, mixing corn starch with water to adjust to 30%-32% concentration, then put sodium carbonate solution to process the liquid to get a best PH value 6.0-6.5. Attention, for keep the activation of the enzyme, each kg. starch must add 500mg calcium chloride and 5-10mg common salt.

2. Liquefaction of high fructose corn syrup manufacturing process:Making the starch liquid PH value to 615, then add certain liquifying enzyme, send to first jet and liquefied process. In this process, heating the temperature increased to 110℃ directly, waiting for about 15mins, make second liquefied process, in this, the temperature get to 135℃, add liquifying enzyme again, this time the liquid can degradation thoroughly, this high fructose corn syrup process part cost time about 2h.This high fructose corn syrup manufacturing process section equipment requests is: jet cooker, enzyme measuring pump, maintaining tank, flash tank, plate type cooler.

3. Saccharifying system:Put hydrochloric acid to make PH value to 415, and processed by cooler to decreased the temperature under 50℃, then add composite glycosydase, this enzyme will complete the whole hydrolysis process of carbohydrates in the liquid. After we can get the sacchafifying liquid with 95DE for high fructose corn syrup manufacturing process.This part need equipments: PH value adjust tank, saccharification tank.

4. Vacuum rotary filtering process of high fructose corn syrup manufacturing process:Vacuum rotary filter main function is filtering the impurities, the rotary drum keep continous working to reached best filtering speed.Main equipments used for high fructose corn syrup manufacturing process in this section: vacuum filter machine, liquid seperator, vacuum pump.

5. High fructose corn syrup decoloration process: put active carbon which is not insoluble in water to liquid glucose to get bright syrup, then use pressure filter to remove the carbon and other impurities.This high fructose corn syrup manufacturing process requests equipment: decoloration tank, plate frame filter press machine, pressure filter, collecting tank for carbon.

6. Ion exchange section: This section is for filter the watersoluble impurities.

7. Isomerism: the mixed liquid syrup enters to heterogeneous tank high fructose corn syrup manufacturing process containing isomerism enzymes, 42% glucose is processed to fructose, then get 42% high fructose corn syrup.

8. Ion exchange process again, this process keep the fructose syrup making pure.

9. Evaporation and concentration section for syrup: this section usually used three-effect evaporator to get the requests high fructose corn syrup products.

Some products sugar can be replaced by fructose syrup. Compared with sugar, fructose syrup has the advantages of high solubility, high stability of fermentation, high permeability and moisture absorption and strong moisturizing properties, etc., which are more widely used in food industry, especially in beverage production.
