Step-by-Step Sorbitol Manufacturing Process
The sorbitol manufacturing process involves a series of chemical and physical steps to convert glucose into sorbitol with high purity and stability. Below is a detailed breakdown:
Preparation of Glucose Solution
Starch is hydrolyze using enzymes or acid hydrolysis to produce glucose syrup. This syrup is filtered and decolorized using activated carbon.Hydrogenation Reaction
The purified glucose solution is pumped into a high-pressure hydrogenation reactor. In the presence of a nickel catalyst and under 150–250°C temperature and 30–80 bar pressure, glucose is converted into sorbitol.Filtration and Catalyst Removal
The reaction mixture is cooled and filtered to remove the catalyst. This step is critical to ensure safety and product quality.Evaporation and Concentration
The sorbitol solution is concentrated via evaporators to achieve the desire solid content of 70% or more, depending on end-use.Purification and Polishing
The concentrated solution is further purified using ion-exchange resins and final filtration systems to remove any remaining color, odor, or impurities.Storage and Packaging
The finished sorbitol solution is stored in stainless steel tanks and packed in HDPE drums, IBC totes, or bulk tankers based on customer demand.
