Membrane Separation & Continuous Moving Bed Technology for Sugar Alcohol Production

Product Overview

The sugar alcohol membrane and continuous moving bed (CMB) system is a high-efficiency, modern solution for sugar alcohol extraction and purification. By integrating ceramic membranes, ultrafiltration (UF), nanofiltration (NF), and continuous moving bed technology, the system achieves fermentation broth clarification, protein and impurity removal, sugar alcohol concentration, ash removal, and industrial chromatography purification. This ensures high purity and yield while reducing resin and chemical usage, optimizing production efficiency and resource utilization.

Working Principle

• Ceramic Membrane Technology: Replaces traditional plate-and-frame filtration to remove large particles and suspended solids from fermentation broth, improving filtrate clarity and reducing resin contamination and microbial residue.

• Ultrafiltration (UF): Removes proteins and pigments while retaining active components, enhancing final sugar alcohol quality.

• Nanofiltration (NF): Concentrates sugar alcohol, reducing or shortening evaporation time, improving crystallization yield, minimizing evaporation losses, and removing soluble macromolecular impurities to increase purity.

• Continuous Moving Bed (CMB) Technology: Replaces fixed beds for ash removal, significantly reducing resin and chemical consumption, optimizing water usage and process efficiency.

• Industrial Chromatography: Optimizes separation for higher resin utilization and sugar alcohol yield, ensuring high-efficiency purification.

Key Features

• Enhanced Filtrate Quality: Efficiently removes fermentation broth impurities, ensuring high product clarity and consistency.

• Resource Saving: CMB technology greatly reduces resin, chemical, and water usage.
• Shorter Processing Time: UF and NF reduce evaporation concentration time, improving production efficiency.
• User-Friendly Operation: Compact process design supports automation, reducing labor requirements.

• High-Purity Output: Combined membrane and chromatography separation ensures high-purity sugar alcohols with excellent yield.
