Process Technologies
Explore our advanced sugar refining solutions designed to enhance efficiency, colour, and reduced costs across every stage of the process.
Phosphoflotation: Efficient Color & Turbidity Removal
Phosphoflotation clarifies sugar melt by removing suspended solids and color through a controlled chemical reaction. The melt is heated to 85°C and mixed with lime sucrate, phosphoric acid, and a color precipitant. This process creates flocs that rise to the surface and are separated, resulting in a cleaner, brighter product with balanced pH.
Carbonation: Crystal-Clear Purification
Carbonation is a widely used purification technique in sugar refining. It involves the addition of lime followed by carbon dioxide gas, forming calcium carbonate crystals. These crystals absorb colouring matter and impurities and act as a natural filter aid. The result is sparkling clear liquor with extremely low turbidity—ideal for further decolorization steps.
Decanter-Based Mud Removal: Superior Mud Separation
Muddy juice from clarifiers is sent to high-performance centrifuge decanters. The decanter uses centrifugal force to separate solids from the liquid. Adding flocculants enhances separation, making this system highly efficient for mud removal while improving overall juice clarity. Replaces cumbersome rotary vaccum filters, eliminating the use of bagacillo that can be valorized for high financial returns.
Brine & Rinse Water Recovery: Membrane-Based Sustainability
The membrane system effectively recovers water from spent brine and rinse streams by separating low-salinity permeate and high-salinity reject. Custom membranes tolerate high BOD/COD loads and reduce fouling via internal turbulence. This eco-friendly system supports recycling, water conservation, and cost reduction. An added feature is ZLD: Zero Liquid Discharge that results in nil effluent.
Ion Exchange Technology: Smart Decolorization
Ion exchange provides a low-cost, high-efficiency method for removing color from sugar melt. The melt is passed through specialized ion exchange resin columns that trap color precursors. Resins are regenerated with a sodium chloride solution, offering long-term performance and reduced operational costs. This system works synergistically with phosphoflotation or carbonation for enhanced results.
Liquid Sugar
Liquid sugar is a ready-to-use, purified sugar solution widely used in beverages, dairy, and food processing industries. Our process has the flexibility of either producing bacteria-free liquid sugar or liquid invert sugar. It is a win-win model for the users and the manufactures, saving money for both.
Multi-Bed Filter (MBF): Deep Filtration Excellence
Our Multi-Bed Filters (MBF) eliminates suspended solids post-clarification using a graded filtration media bed. Coarse media at the top capture larger particles, while finer media below trap smaller ones. This layered design maximizes filtration depth and ensures high clarity with minimal media blinding.
SRT Clarifier: High-Speed Juice Clarification
Our Short Retention Time Clarifier ensures fast and efficient separation of impurities from sugarcane juice. Juice enters via a circular channel and is distributed by a deflector system. Settled mud is continuously scraped and removed, while clarified juice overflows through dual notched down gutters—ensuring a steady flow of clear juice with minimal retention time thereby cutting inversion losses.
PAC/GAC Treatment: Advanced Carbon Filtration
For superior liquor polishing, we use powdered or granular activated carbon (PAC/GAC) combined with filter aid. Heated liquor is mixed in a carbon reaction tank and retained for 20–30 minutes before filtration through a membrane filter press. The process includes pre-coating, filtration, and cake washing, ensuring high color removal and clarity.
