一、Process Flow

二、Process Description

(1) Modulation: adjust the concentration of starch in the starch factory to 17-19Be with water, and adjust the pH and temperature.

(2) Liquefaction: Transfer the starch milk to the buffer tank, add the appropriate amount of enzyme preparation, and use the ejector to heat and mix to keep warm and liquefy.

(3) Saccharification: The liquefied liquid is cooled to a certain temperature, the pH value is adjusted, an appropriate amount of enzyme preparation is added, and transferred to the saccharification tank, the saccharification reaches the required DE value within a specified time, and then the enzyme is discharged.

(4) Filtration and decolorization: The glucose syrup passes through the filter to remove protein and other impurities, then add activated carbon at the appropriate temperature to decolorize within a specified time, and then send it to the filter to remove the activated carbon, and the clear liquid is sent to the next process.

(5) Ion exchange: At a certain temperature, the glucose solution enters the cation resin and anion resin exchangers to remove inorganic salts and pigments and other organic impurities to obtain refined filtrate.

(6) Evaporation: The glucose liquid is sent to the evaporator through a precision filter to be concentrated to reach the required product concentration, and then transferred to the next process.

(7) Isomerization: The glucose solution is added with chemicals, the pH value is adjusted, the temperature is stabilized, and it is transported to the isomerization column to produce fructose under the action of the isomerase, and the fructose content reaches 42% or more.

(8) Decolorization: F42 fructose syrup is added with activated carbon, decolorized at a certain temperature, and transferred to a filter to remove the activated carbon to obtain a clear fructose syrup clear solution.

(9) Ion exchange: F42 fructose syrup is processed into cation resin and anion resin exchangers at a certain temperature to remove inorganic salts and pigments and other organic impurities to obtain refined filtrate.

(10) Evaporation: F42 fructose syrup is sent to the evaporator through a precision filter for concentration to achieve the desired product concentration.

(11) Finished product: F42 fructose syrup is filled and weighed, packaged and stored in the warehouse.
