Dextrose Monohydrate

Dextrose monohydrate is a monosaccharide organic compound produced from starch by acid hydrolysis or enzymatic hydrolysis, which is widely used in food, medicine, cosmetics and many other industries.

Process Flow Chart

Process Description

(1) Conditioning of starch milk: adjust the concentration of starch slurry 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 starch enzyme for preparation, and use the jet cooker to heat up and mixing efficiently.  

(3) Saccharification: The liquefied liquid is then cooled to a certain temperature, after the pH adjustment, appropriate amount of saccharification enzyme will be added, and transferred to the saccharification tanks, when the syrup reaches the required DE value within certain time, the saccharification step will be completed.

(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 decolorization with certain time, and then send it to the filter to remove the activated carbon, and the clear liquid will be sent to the ion exchanger.

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

(6) Evaporation: The glucose syrup is sent to the evaporator through a safety filter to be concentrated to achieve the desired concentration, and then transferred to the next process.

(7) Cooling and crystallization: Add a certain amount of seeding crystals to the concentrated glucose syrup, gradually cooling down, and glucose will be crystallized.

(8) Centrifugal separation: The sugar massecuite is sent to the centrifuge to separate the wet sugar, and the mother liquor is recycled back for further crystallization(different crystallization strategy can be applied).

(9) Drying: Wet sugar is sent to the dryer for drying to obtain the qualified product with required moisture.

(10) Finished product: glucose products are weighed and packaged, and stored in the warehouse.
