Refined Rice Bran Wax Equipment

Rice bran wax is a natural wax product. It has wide applications, including cosmetics, lubricants, and waterproofing agents. In rice bran wax production, refining is a critical step to ensure product quality and performance. Below is a detail of the refined rice bran wax production process.

Raw Material Selection and Pretreatment

1. Rice bran selection: Select fresh, dry rice bran free of impurities to guarantee extraction yield and purity during subsequent processing.
2. Rice bran pretreatment: Crush and screen the rice bran to remove impurities and larger particles, facilitating subsequent extraction.

Rice Bran Wax Extraction

Solvent Extraction Method

Use organic solvents such as petroleum ether or ethanol to macerate the pretreated rice bran. Control solvent dosage, extraction temperature, and duration to ensure complete dissolution of rice bran wax in the solvent.

Filtration and Separation

Filter the extraction solution to remove solid residues. Then, separate solvent from the rice bran wax through distillation, cooling, or similar methods.

Rice Bran Wax Refining

Decolorization

To improve rice bran wax color quality, require decolorization process. Common decolorizing agents include activated carbon and kaolin, which remove pigments and impurities through adsorption.

Filtration and Impurity Removal 

Decolorized rice bran wax undergoes further filtration to eliminate solid residues and fine particles generated during decolorization.

Crystallization and Separation

The filtered rice bran wax is cooled to induce crystallization, causing the wax components to precipitate as solids. Centrifugation and filtration methods are then employed to separate the wax components from liquid impurities.

Refined Rice Bran Wax Packaging and Storage

1. Packaging: Refined rice bran wax is packaged using materials with excellent sealing properties to prevent moisture absorption, oxidation, or contamination during storage and transportation.
2. Storage: Refined rice bran wax should be stored in a dry, cool, and well-ventilated warehouse, shielded from direct sunlight and high temperatures. Storage conditions must be regularly inspected to ensure product quality.

Process Optimization and Quality Control

• Process Optimization: Refine extraction parameters such as temperature, duration, and solvent dosage to enhance rice bran wax yield and purity. Tailor refining conditions to meet diverse customer requirements based on specific product specifications.
• Quality Control: Implement a rigorous quality control system involving thorough testing and evaluation of raw materials, semi-finished products, and finished goods. Chemical analysis and physical property testing ensure product compliance with relevant standards and customer specifications.

Conclusion

In conclusion, refined rice bran wax production involves multiple stages: raw material selection and pretreatment, wax extraction, refining, packaging and storage.

Through process optimization, enhanced quality control, and continuous improvement, high-purity, can produce premium-quality rice bran wax products to meet diverse industrial demands.
