Factory-direct activated carbon from our production base in Shizuishan, Ningxia
Food, Sweetener & Pharma Refining
Match powdered activated carbon to the actual food or beverage process liquid, color target, dose, pH and filtration requirements.
Recommended carbon
Wood based PAC, commonly 200 or 325 mesh, qualified by actual-liquid decolorization and filtration testing
Powdered · PAC
Fine powdered activated carbon for liquid decolorization, specified by target liquid, mesh passing rate, methylene blue, pH, ash and filtration behavior.
Mainly wood-based, steam or phosphoric acid
200 or 325 mesh
Powdered · PAC
Wood based PAC with configurable fineness, methylene blue, pH, ash and filtration properties for liquid-phase dosing and decolorization.
Wood chips, sawdust or wood charcoal
200 or 325 meshGrade matching
Review the target contaminants, carbon grade, sizing and test requirements together.
Reference grades are comparison directions, not a guarantee of interchangeability. Confirm the required specification and application testing before substitution.
Specification
The reference ranges most RFQs start from, before process conditions narrow them down.
| Primary sourcing direction | Wood based PAC, commonly 200 or 325 mesh, qualified by actual-liquid decolorization and filtration testing |
|---|---|
| Common particle size | 200 or 325 mesh, specified with a minimum target passing rate |
| Methylene blue | Common target range: 150-200 mg/g |
| Iodine value | Typical supporting range: 800-1,050 mg/g |
| Ash | Common target: <=5-10% |
| Moisture | Typically <=5% |
| Application-specific checks | Caramel or molasses decolorization, iron, chloride, phosphate, filtration time and testing against the actual liquid |
Food-contact or drinking-water compliance is not a blanket product claim. Applicable documents and contaminant limits must be confirmed for the selected grade and destination market.
Food-process equipment reference. PAC performance and documentation must be confirmed for the actual liquid, filtration method and destination market.
Food and beverage decolorization should be qualified with the actual process liquid because color bodies, pH and dissolved solids can change adsorption and filtration behavior. Compare candidate PAC grades at equal dose and contact time, then confirm filtration, carryover and destination-specific documents for the selected grade.
Compare color removal, dose and filtration time in representative syrup at the process pH and temperature.
Run actual-liquid trials because acidity and dissolved solids can affect adsorption and filtration.
Review pretreatment, temperature, dose, filtration behavior and grade-specific contaminant limits.
Confirm the color target, contact time, carbon separation, carryover limit and applicable documents.
System design
Confirm these reference conditions against the actual process and equipment.
Typical Batch Dosage Rate
0.1% – 1.5% wt/wt based on dry dissolved solids (optimized via laboratory isotherm jar test)
Process Operating Temperature
60 – 85 °C
Agitated Contact Time
20 – 45 minutes under uniform mechanical mixing prior to filtration
Process pH Control
Matched to liquid stability window (e.g., pH 5.5–6.5 for sucrose to avoid acid inversion)
Solid-Liquid Separation
Pre-coated leaf/candle filters, plate-and-frame filter press (with diatomaceous earth/perlite body feed)
Purity & Food-Contact Review
Lot-specific COA for ash, moisture, pH, iron, chloride, and heavy metals (FCC/USP methods available)
Published design practice for sourcing reference, not a guarantee for a specific system.
Grade review
Liquid identity and composition, initial and target color, pH, dosage, contact time, temperature, filtration method, required documents, quantity and packing.
Process factors to specify
Recommended qualification path
FAQ
Testing against the actual liquid is strongest. Methylene blue, caramel or molasses value, pH, ash, iron and filtration time help compare candidate grades.
PAC must be removed after adsorption. A high adsorption index can still be impractical if the carbon blinds filters, filters too slowly or creates unacceptable carryover.
Documents are reviewed for the selected grade and destination regulation. They are not assumed from a generic food or beverage application name.
Technical library
· Food & Pharma Decolorization
Match phosphoric-acid and steam-activated wood PAC mesopore and macropore indices (methylene blue, caramel A-grade, and molasses number) to target color bodies in cane/beet sugar syrups, citric acid, edible oil PAH4 bleaching, and pharmaceutical APIs.
· Process Treatment
Powder activated carbon is only a good fit when the system can dose, mix, and separate fine PAC. Use this process-fit guide to check mesh size, slurry behavior, filtration risk, packing, and inquiry fields before sourcing.
