ZOILSIL-G300 High Purity Food Grade Silica Gel Adsorbent for Professional Oil Refining
In the edible oil and industrial grease processing industry, the efficiency of adsorption purification directly determines the final product quality, stability and production cost. As a high-performance porous silica adsorbent developed for oil refining scenarios, ZOILSIL-G300 provides a reliable solution for dephosphorization, degumming, heavy metal removal and filtration optimization in vegetable oil, animal fat and industrial grease production.
Core Technical Specifications
ZOILSIL-G300 is a micron-sized porous silica gel powder with strictly controlled physicochemical indexes, and all indicators meet national food additive standards:
· SiO₂ purity (dry basis): ≥99.0%, typical value 99.3%
· BET specific surface area: 500–750 m²/g, typical value 710 m²/g
· Particle size D50: 15.0–25.0 μm, typical value 18.2 μm
· Loss on drying (160°C): 57–63%
· Ignition loss (1000°C, 1h): ≤8.5%, typical value 5.9%
· pH (25% aqueous suspension): 1.5–3.0, typical value 2.6
· Ultra-low impurity control: Pb < 1 ppm, As 0.4 ppm, Hg 0.5 ppm, Na₂O < 1 mg/g
Core Performance Advantages
1. Selective adsorption of polar impurities The rich porous structure and surface properties enable efficient adsorption of gums, phospholipids, trace metals (calcium, magnesium, iron) and residual soap in oils, while retaining the natural flavor and color of oil products, avoiding the flavor loss caused by traditional adsorbents.
2. Excellent filtration performance The optimized particle size distribution forms a uniform filter cake structure, reduces pore blockage of filter media, extends filtration cycle, improves production efficiency and reduces oil entrainment loss in filter cake.
3. High purity and food safety The product complies with food additive standards, passes HACCP and FAMI-QS system certification, and has extremely strict control over heavy metals and trace impurities, which is suitable for high-end edible oil and food-grade grease processing.
Main Application Scenarios
· Vegetable oil refining: degumming, dephosphorization and heavy metal removal of soybean oil, rapeseed oil, palm oil, sunflower oil, etc.
· Butter and animal fat processing: removing gum impurities, improving clarity and retaining milk flavor
· Industrial grease purification: removing polar impurities and solid particles to improve oil stability
· Frying oil purification: adsorbing carbonized residues and oxidation products to extend oil service life
