Sunresin Continuous Chromatography and Resin Solutions for the Amino Acid Industry
Industry Background: Rising Demands for Purity, Yield and Cost Control
The amino acid industry is undergoing rapid expansion driven by feed, food, pharmaceutical and bio-based material applications. At the same time, producers are facing stricter purity standards, tighter environmental regulations, and increasing pressure to maximize yield while reducing operational cost. Traditional batch purification methods often struggle with low efficiency, high solvent consumption and unstable product quality.
To address these challenges, Sunresin has developed advanced resin materials and integrated continuous separation technologies specifically designed for large-scale amino acid production. Through continuous innovation in material science and process engineering, Sunresin provides industrially proven purification solutions covering fermentation broth treatment, mother liquor recovery, desalination and high-resolution amino acid separation.
Core Material Technology: Sunresin Monojet™ Uniform Particle Resin
At the heart of Sunresin amino acid solutions is Monojet™ uniform particle resin technology. Manufactured using advanced jet polymerization processes, Sunresin Monojet™ resins feature highly uniform particle size distribution, excellent mechanical strength and stable chemical performance.
For amino acid purification, uniform particle size significantly improves mass transfer efficiency and chromatographic resolution. This is especially critical when separating structurally similar amino acids such as leucine and isoleucine, or when refining products such as lysine, valine, tryptophan, glycine, arginine, alanine and methionine.
Sunresin Monojet™ resins provide lower pressure drop, higher separation precision and longer service life under continuous operation, enabling customers to achieve consistent product quality while reducing maintenance frequency and resin replacement costs.
Continuous Separation Upgrade: Sunresin SSMB Chromatography Systems
To further enhance production efficiency, Sunresin integrates Monojet™ chromatography resins with proprietary Sunresin SSMB continuous chromatography systems.
Sunresin SSMB technology enables continuous feed and discharge, significantly increasing productivity compared with traditional batch chromatography. The system improves recovery rate, reduces water and solvent consumption, lowers energy usage and enhances automation level.
In recent years, Sunresin has delivered large volumes of uniform particle chromatography resin and successfully implemented dozens of SSMB continuous chromatography systems across fermentation and bio-based industries. Within the amino acid sector, Sunresin SSMB systems have been applied in amino acid mother liquor separation, high-purity amino acid refinement and complex mixture fractionation. These industrial projects demonstrate stable operation, scalable capacity and reliable long-term performance.
Through the combination of Sunresin advanced resin materials and Sunresin SSMB equipment engineering, customers receive a fully integrated purification solution rather than isolated equipment or resin supply.
Complementary Technology: Sunresin Continuous Ion Exchange Systems
In addition to chromatography, Sunresin provides continuous ion exchange systems that further optimize desalination and impurity removal steps in amino acid production.
Sunresin valve-array continuous ion exchange systems and large-column ion exchange systems are designed to reduce chemical consumption, improve regeneration efficiency and maintain stable continuous operation. When combined with Sunresin uniform particle resins, these systems maximize separation efficiency while lowering total operating costs.
This integrated “resin + system + process” approach allows Sunresin to deliver customized purification solutions tailored to different amino acid production scales and process routes.
Proven Industrial Applications in the Amino Acid Sector
Sunresin has accumulated extensive industrial experience in the amino acid industry not only across China but also in international markets over the past several years. Multiple large-scale projects have been implemented, including amino acid SSMB purification systems, mother liquor recovery systems, desalination units and integrated chromatography-resin packages.
These projects involve applications such as tryptophan separation, valine purification, glycine mother liquor desalination and comprehensive amino acid fractionation systems. The successful operation of these installations demonstrates Sunresin’s capability in process design, equipment integration and industrial-scale commissioning.
By combining advanced material science with strong engineering capability, Sunresin has helped amino acid producers improve product purity, increase recovery rate, reduce chemical consumption and enhance overall plant efficiency.
Customer Value: Efficiency, Stability and Sustainability
Through Sunresin amino acid purification solutions, customers benefit from improved yield, enhanced separation accuracy, lower operating costs and more stable production performance. Continuous operation reduces resource consumption and supports environmental compliance.
Sunresin continues to invest in resin innovation and continuous separation technologies to meet the evolving needs of the global amino acid industry. By integrating Monojet™ uniform particle resins, SSMB continuous chromatography systems and continuous ion exchange technology, Sunresin enables amino acid manufacturers to transition from traditional batch processing to efficient, automated and sustainable continuous production.
With proven industrial cases, advanced technology platforms and comprehensive engineering support, Sunresin remains a reliable technology partner for the amino acid industry worldwide.
