Sorbitol is a colorless transparent liquid produced by the hydrogenation reaction of glucose under the action of a catalyst. It has a cool sweet taste, is easily soluble in water, and is difficult to dissolve in organic solvents. Widely used in food, beverage, medicine, cosmetic industry and many other industries.

Process Flow Chart

Process Description

(1) Glucose syrup:  the raw materials which prepared by enzymatic process, typically coming from starch.

(2) Pre-preparation: Prepare a certain concentration of glucose syrup, add catalysts and adjust the pH at right level.

(3) Hydrogenation reaction: The prepared materials are sent to the reactors, heating and introduce hydrogen into the reactors, sorbitol will be generated under high temperature and high pressure conditions.

(4) Catalysts precipitation & filtration: The sorbitol liquid after the reaction is sent to the precipitation tank, after a certain time, the catalyst is removed, and sent to the next process.

(5) Decolorization and filtration: A certain amount of activated carbon is added to the sorbitol solution, maintained at a certain temperature, and maintained for a certain time for decolorization, and then sent to filters to remove the activated carbon in order to obtain a transparent clear syrup.

(6) Ion exchange: At a certain temperature, the sorbitol syrup will enters the cation resin and anion resin columns for treatment to remove impurities such as inorganic salts and trace colorants to obtain a refined transparent syrup.

(7) Evaporation: The sorbitol liquid passes through a safety filter then sent to the evaporator for concentration to obtain the product with the required concentration.

(8) Finished product packaging: Sorbitol products are filled and weighed, and then stored in the warehouse after packaging.
