Rice bran wax is an important byproduct of rice bran oil processing. Extracting rice bran wax from the wax paste — a byproduct of rice bran oil refining — not only significantly improves the quality of rice bran oil, but the extracted wax also holds considerable value across the food, daily chemical and chemical industries.
Refined rice bran wax is a white, pale yellow or brown solid with a certain degree of hardness. It is brittle (non-sticky), has a high melting point of approximately 78.2°C, fine crystals, a smooth surface and good electrical insulation properties. Huatai’s refining process emphasizes environmental protection and efficiency, using food-grade solvents and molecular distillation to improve product purity while strictly controlling temperature and time for consistent quality.
With global mining of non-renewable lignite wax declining year by year (current supply approximately 35,000–40,000 tons, concentrated in Europe), rice bran wax — extracted from pure natural green plants — is a renewable substitute bringing new development opportunities to related industries. Huatai holds globally exclusive technology for rice bran wax deep processing.
From rice bran byproduct to high-purity refined wax — a fully integrated process.
Select fresh, dry rice bran free of impurities to guarantee extraction yield and purity during subsequent processing.
Crush and screen the rice bran to remove impurities and larger particles, facilitating subsequent solvent extraction.
Macerate the pretreated rice bran with food-grade solvents such as petroleum ether or ethanol; control solvent dosage, extraction temperature and duration for complete wax dissolution.
Filter the extraction solution to remove solid residues, then separate solvent from wax through distillation, cooling or similar methods.
Remove pigments and impurities using adsorbents such as activated carbon and kaolin through adsorption, improving the color quality of the wax.
Filter the decolorized wax to eliminate solid residues and fine particles generated during decolorization.
Cool the filtered wax to induce crystallization, causing wax components to precipitate as solids; then separate them from liquid impurities via centrifugation and filtration.
Pass the upper mixed oil through an evaporation system to recover solvent and yield neutral oil; the lower crystallized mixed wax enters a rotary drum vacuum filter to separate solid wax from oil.
Heat the solid wax and vacuum-evaporate to concentrate, removing trace solvent and moisture; the liquid wax is then cooled and granulated to obtain refined rice bran wax.
Each system is designed and manufactured in-house under ISO 9001 quality management.
Magnetic separator, vibrating screen, crusher and sifter for rice bran cleaning and particle-size preparation before extraction.
Stainless-steel extraction tanks with controlled temperature and reflux condensation for food-grade solvent percolation and wax dissolution.
Plate-and-frame filters and distillation columns for solid removal and solvent recovery from the wax-oil mixture.
Activated carbon / kaolin adsorption vessels and controlled cooling crystallization tanks for wax purification and solid separation.
Rotary drum vacuum filter, vacuum evaporator and granulator producing refined rice bran wax granules with trace solvent removed.
Engineering innovations that deliver superior performance and lower operating costs.
Huatai holds globally exclusive technology for rice bran wax deep processing, integrating physical and chemical reactions to solve industrial refining challenges with high efficiency and low cost.
Food-grade solvent extraction combined with molecular distillation improves product purity; strictly controlled temperature and time ensure consistent, stable quality.
Refined rice bran wax is a renewable plant-based substitute for non-renewable lignite wax (global supply declining), opening new markets in chemical, food and daily chemical industries.
Henan Huatai Intelligent Equipment Group was founded in 1988 and has grown into one of China’s major grain and oil machinery manufacturing enterprises. We integrate research and development, engineering design, equipment manufacturing, on-site installation and commissioning under one roof.
