Why is Pea Protein Gaining Global Popularity?
As the global plant-based protein market expands, pea protein has become a star ingredient due to its high nutritional value, non-allergenic properties, gluten-free profile, and sustainable cultivation. It’s increasingly used in food products, nutritional supplements, sports nutrition, and vegan applications—particularly as an alternative to soy protein.
Why Pre-Extraction Grinding Matters
Pea protein extraction involves several stages, and fine grinding is the key pre-treatment step. It directly influences the extraction yield, solubility, filtration efficiency, and even the texture of the final product.
Common challenges include:
* Uneven particle size distribution affecting protein release and filtration
* Protein denaturation due to heat generated during milling
* Powder agglomeration causing poor solubility and low flowability
Choosing a grinding system that delivers controlled particle size, low thermal impact, and hygienic operation is essential for product consistency and performance.
Why Impact Mills Are the Optimal Choice
Advantages of the Impact Mill:
* Low Heat Generation: High-speed shearing ensures minimal temperature rise, preserving protein activity
* Precise Particle Size Control: Integrated classifier allows D50 particle sizes between 20–100μm
* Effective Deagglomeration: Enhances cell rupture and protein release
* Food-Grade Design: Compact structure, easy cleaning, and hygienic finishes
Impact mills are ideal for:
* Dry pre-treatment in protein extraction workflows
* Continuous, large-scale production with consistent particle size
* Cleanroom or low-contamination food production environments
