On August 29, Henan Huatai Intelligent Equipment Group successfully delivered its advanced 100T/D soybean oil refining plant to Dalian, Liaoning Province. This milestone project introduces efficient soybean oil refining technology to the Liaoning region, setting a new benchmark for edible oil processing in China.
Why choose Huatai soybean oil refining machine?
The 100T/D soybean oil refining plant integrates a complete set of premium oil refining equipment, including processes such as neutralization, bleaching, deodorization, and dewaxing.What sets Huatai’s system apart is its targeted removal of hazardous micro-contaminants: plasticizers (e.g., DEHP, DBP), organophosphorus pesticide residues, 3-monochloropropane-1,2-diol esters (3-MCPDE), glycidyl esters (GE), and trans fatty acids (TFAs). These harmful compounds are effectively removed through optimized physical refining (high-temperature steam distillation) and chemical refining (alkali neutralization) processes, ensuring that the final oil meets or exceeds the national standard GB/T 1535—2017 for soybean oil. By minimizing these contaminants, Huatai’s soybean oil refining machines produce high-quality edible oil with excellent oxidative stability, a lighter color, and a more neutral flavor, making it an ideal choice for both direct consumption and industrial food processing.
Soybean Oil Refining Process
- Degumming — Removes hydratable and non-hydratable phospholipids (lecithin) using food-grade phosphoric acid, reducing phosphorus content to below 5 ppm, which prevents darkening during high-temperature deodorization.
- Neutralization — Employs caustic soda (NaOH) to neutralize free fatty acids (FFA), producing soapstocks that are separated via high-speed centrifugal separators. Removes free fatty acids (FFA) to improve stability.
- Bleaching — Uses activated clay (acid-activated montmorillonite) at 90–110°C under vacuum to adsorb pigments (chlorophyll, carotenoids), trace metals (iron, copper), and primary oxidation products (peroxides). The bleaching earth dosage is precisely controlled at 1–3% to maximize color removal while minimizing oil loss.
- Deodorization — Removes off-odors (e.g., bean odor, burnt odor) to achieve a neutral taste profile.
This fully automated soybean oil refining plant features high refining efficiency, low energy consumption, and environmentally friendly production, making it an ideal choice for large-scale soybean oil production.
