一、Process Flow

二、Process Description

(1) Glucose syrup: a transparent liquid refined by enzymatic hydrolysis using starch as raw material.

(2) Ingredients: Prepare a certain concentration of glucose syrup, add a catalyst, and adjust the pH value.

(3) Hydrogenation reaction: The prepared materials are sent to the reaction kettle, heated, and hydrogen is added, and the high temperature and high pressure reaction obtains the sorbitol solution.

(4) Settling filtration: The sorbitol liquid after the reaction is sent to the settling tank, settling for 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 period of decolorization, and then sent to a filter to remove the activated carbon to obtain a transparent clear solution.

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

(7) Evaporation: The sorbitol liquid passes through a precision filter and is 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.
