Polyols, also known as sugar alcohols, are widely used in the food, confectionery, pharmaceutical, oral care, and chemical industries as low-calorie sweeteners, humectants, and functional ingredients.
Our integrated polyol processing solutions cover the complete production process, from carbohydrate feed preparation and catalytic hydrogenation to purification, concentration, and final product handling.
Catalytic Hydrogenation & Process Principles
The core process in polyol production is the catalytic hydrogenation of carbohydrate feedstocks. During hydrogenation, the carbonyl groups of reducing sugars are converted into hydroxyl groups using hydrogen and suitable catalysts under carefully controlled operating conditions.
The reactor system is designed to provide efficient gas-liquid contact, heat transfer, and reaction control for reliable and consistent production.
Integrated Process Steps
-
Feedstock Conditioning & Pre-Treatment
Preparation and conditioning of glucose, maltose, or other carbohydrate syrups through concentration adjustment, pH control, and filtration.
-
Catalytic Hydrogenation
Controlled hydrogenation using dedicated reactors designed for efficient hydrogen dispersion and mass transfer.
-
Catalyst Separation & Recovery
Efficient filtration and separation systems for catalyst recovery and recycling, minimizing material losses.
-
Purification & Ion Exchange
Removal of inorganic salts, residual catalyst-related impurities, organic acids, and other dissolved contaminants through ion exchange and filtration technologies.
-
Decolorization & Polishing
Activated carbon and adsorption technologies are used to improve product color, clarity, and overall quality.
-
Concentration & Finishing
Energy-efficient evaporation systems concentrate the purified polyol solution to the required dry-solids concentration. Crystallization and drying can be integrated for solid polyol products.
Engineering & Automation
Complete process lines can be integrated with PLC/SCADA automation, online process monitoring, recipe management, safety interlocks, and automated cleaning and regeneration systems.
The process design focuses on reliable operation, efficient energy and resource utilization, catalyst recovery, and consistent product quality.
Applications
Polyol processing technologies can be applied to the production of Sorbitol, Maltitol, Mannitol, Xylitol, Isomalt, Lactitol, and other specialty polyol products for food, confectionery, pharmaceutical, oral care, and chemical applications.
From process design to commissioning, integrated solutions can be tailored to production capacity, raw material characteristics, and final product requirements.
