Key Stages in Rice Bran Oil Extraction

The rice bran oil extraction process consists of several critical stages, each involving specialized equipment designed to maximize yield and purity. These stages include:

  • Raw Material Pre-treatment
  • Oil Extraction
  • Refining
  • Supporting Equipment

Pre-treatment Equipment: Enhancing Purity and Efficiency

Pre-treatment plays a vital role in preparing rice bran for efficient oil extraction. Key equipment includes:

Equipment Function Technical Parameters
Sorting Machine Removes impurities and foreign materials Capacity: 5-10 tons/hour
Expander Improves oil release by increasing surface area Temperature range: 100-150°C
Sunflower Seeds

Extraction Equipment: Working Principles and Technical Advantages

The core of the rice bran oil extraction process lies in the use of advanced extraction equipment such as solvent extractors and evaporation towers. These devices ensure maximum oil recovery while maintaining product quality.

Common types of extraction systems include:

  • Batch Extractor: Suitable for small-scale operations
  • Continuous Extractor: Ideal for large-volume processing

Technical advantages of modern extraction systems include:

  • High solvent recovery rates (up to 98%)
  • Low energy consumption
  • Minimal oil degradation

Refining Equipment: Ensuring Product Quality

Refining is crucial for removing impurities and improving the stability and shelf life of rice bran oil. The main refining steps include:

  1. De-gumming: Removes phospholipids and other gums
  2. De-acidification: Neutralizes free fatty acids
  3. Decolorization: Eliminates pigments using activated carbon
  4. Deodorization: Removes off-flavors and odors at high temperatures

Each step requires specific equipment, such as de-gumming tanks, neutralizers, decolorizers, and deodorizers.
