Peas, known for their high protein content and low allergenicity, have become a crucial raw material in the production of plant-based foods and nutritional supplements. As global demand for plant-based diets continues to rise, extracting high-value components such as plant proteins, dietary fibers, and starches from peas has become increasingly important. However, achieving efficient separation while maintaining the integrity of these nutrients remains a major challenge for many food manufacturers.
The Air Classifier Mill (ACM) offers an effective solution. This advanced grinding system combines impact grinding and precise air classification, enabling fine, uniform particle size distribution while preserving the functional properties of pea components. In this article, we explore how the air classifier mill enhances the efficiency and quality of the pea extraction process.
How the Air Classifier Mill Works
The air classifier mill operates on the principle of high-speed impact and integrated classification. Inside the mill, rotating hammers or blades impact and shear the pea material into fine particles. At the same time, the built-in air classifier continuously separates fine protein-rich particles from coarser starch fractions.
The fine protein particles are collected through a cyclone and dust collector, while larger starch particles are returned for further grinding. Compared to traditional grinding systems, the air classifier mill ensures narrower particle size distribution and precise control, improving the overall efficiency of pea component extraction.
Advantages of Air Classifier Mill in Pea Extraction
Increased Extraction Efficiency
By grinding peas into micron-level powders and simultaneously classifying them, the Air Classifier Mill significantly improves extraction rates for proteins, fibers, and starches — without the need for multiple separate processing steps.
Precise Particle Size Control
The Air Classifier Mill allows precise adjustment of particle size according to the target application. Whether producing fine pea protein powder or coarser fiber-rich fractions, it ensures consistent and reproducible results.
Preservation of Nutritional Integrity
Thanks to its efficient grinding mechanism and short residence time, the air classifier mill minimizes heat generation. This helps preserve sensitive nutrients such as proteins, amino acids, and fibers, maintaining the high nutritional value of the extracted pea components.
Energy-Efficient and High Performance
The ACM achieves high throughput within a compact design. Its integrated grinding and classification system reduces energy consumption while enhancing productivity — providing a strong advantage for industrial-scale operations.
Environmentally Friendly Operation
The closed-loop design of the air classifier mill minimizes dust emissions and meets modern environmental and occupational health standards. It not only safeguards workers’ health but also supports sustainable and clean manufacturing practices.
Real-World Applications of Air Classifier Mills
An increasing number of global plant-based food manufacturers are adopting Air Classifier Mills for pea extraction. For instance, one leading plant protein producer successfully improved protein yield and reduced energy costs by upgrading its process to ACM systems. This transition enabled the company to meet growing market demand while maintaining stable, high-quality production.
Conclusion
The air classifier mill plays a critical role in modern pea extraction. It offers high efficiency, precise control, and excellent nutrient preservation. As the plant-based food industry continues to grow, ACM technology becomes increasingly important. Many manufacturers now choose it to enhance extraction efficiency and product quality.
