Advanced Air Classification & Milling for High-Protein Enrichment
The global demand for plant-based protein is accelerating across food, nutraceutical, pharmaceutical, and specialty ingredient markets. However, achieving high protein purity, consistent particle size distribution, and optimal yield requires more than conventional grinding methods.
The DP® Proteinova™ Protein Shifting System delivers precision protein enrichment through advanced milling and high-performance air classification technology.
This is not traditional size reduction.
This is engineered protein upgrading.
What Is Protein Shifting?
Protein shifting is a dry fractionation process that separates protein and starch components from pulses, legumes, and other plant-based raw materials using controlled particle size reduction and aerodynamic classification.
Unlike wet extraction methods, protein shifting:
- Eliminates chemical solvents
- Reduces water usage
- Lowers processing costs
- Preserves native protein functionality
- Improves sustainability
The result is a high-protein fine fraction and a starch-rich coarse fraction — both valuable, marketable products.
How the DP® Proteinova™ System Works
The Proteinova™ system integrates two core technologies:
1. DP ACM Air Classifier Mill
Raw protein material is finely ground using a high-speed rotor and precision serrated liner system. Adjustable rotor speed and airflow control allow exact particle size targeting.
2. DP Aerova Air Classifier
The milled material enters a high-efficiency air classification zone where particles are separated based on size and density.
- Fine fraction → High Protein Content (up to ~60%)
- Coarse fraction → High Starch Content
This controlled separation enables consistent, repeatable protein enrichment without over-processing or thermal degradation.
Key Benefits of the DP Proteinova™ Protein Shifting System
- Effective protein–starch separation
- High protein enrichment up to approximately 60%
- Uniform and consistent particle size distribution
- Increased yield and production efficiency
- Energy-efficient dry processing
- Hygienic stainless-steel construction
- Compact and dust-free operation
- Durable, low-maintenance design
For manufacturers processing yellow peas, lentils, chickpeas, soy, and other pulse proteins, this translates directly into higher margins and improved product consistency.
Applications in Plant-Based Protein Production
The DP Proteinova™ system is ideal for:
- Pea protein processing
- Pulse protein fractionation
- Plant-based meat ingredient preparation
- Protein concentrate production
- Functional protein powder manufacturing
- Nutraceutical protein blending
- Specialty food ingredient processing
As consumer demand for clean-label, high-protein formulations grows, protein shifting offers a scalable and sustainable alternative to wet extraction systems.
