The global demand for plant-based proteins, specifically derived from yellow field peas (Pisum sativum), has experienced exponential growth. Driven by consumer preferences for gluten-free, non-GMO, and hypoallergenic ingredients, the market requires state-of-the-art milling systems capable of clean processing. Historically, wet extraction processes dominated pea protein isolate production. However, modern environmental directives and high operating expenses have shifted industrial preferences toward dry fractionation.
Dry fractionation relies heavily on high-precision mechanical milling and air classification. This method separates pea flour into protein-rich (fine) and starch-rich (coarse) fractions without chemical solvents or water consumption. Consequently, selecting a CE Certified Pea Milling Equipment Manufacturer is crucial for global processing plants to guarantee efficiency, plant safety, and regulatory compliance.
Dry processing demands precise control over particle size distribution (PSD). Peas must be dehulled, split, and then micronized using impact or jet mills. If the starch granules are damaged during milling, they release free amylose, which degrades final product quality. Henan Jiujie Machine Co., Ltd. addresses this challenge by utilizing low-temperature, adjustable-speed milling technologies that maintain structural integrity, delivering high-purity protein concentrates while minimizing waste.
Henan Jiujie Machine Co., Ltd. is a professional supplier of complete equipment and engineering services for the food production and grain processing industries. Our business covers a wide range of applications, including wheat flour milling plants, feed processing factories, and rice processing plants. Our product portfolio includes conveying equipment, cleaning equipment, flour milling equipment, and other related machinery. Over the years, our products have been widely recognized by customers both in domestic and international markets.
Since its establishment, Henan Jiujie Machine Co., Ltd. has been dedicated to the research and development of grain processing technology and machinery. With extensive industry experience, we are able to provide integrated solutions across the entire grain and food processing industrial chain. Our solutions cover multiple stages, including raw material collection, storage, cleaning, grading, sieving, grinding, mixing, shaping, production, and packaging.
We act as an integrated engineering partner, not just an equipment supplier. From CAD design to commissioning, we deliver quality assurance at every phase.
Our pea milling equipment fully complies with EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. We guarantee safe electrical circuits, overload protection, and high-efficiency emergency stop systems.
Every phase of production—from design to robotic welding—runs under strict ISO 9001 quality management protocols. Traceability of raw materials and standardized tolerance tests guarantee consistent machine operation.
Our grain cleaning process is designed to operate without water usage, ensuring zero wastewater discharge and supporting environmentally friendly production. This reduces water pollution and cuts utility costs.
Our products are characterized not only by stable performance but also by easy installation, convenient maintenance, and low operating costs. With advanced technology, reliable quality, and modern design, our equipment has earned high appreciation from clients worldwide. By selecting water-free cleaning systems, our plants comply with local environmental discharge regulations, helping factories avoid expensive chemical wastewater treatment systems.

In addition, we are equipped with CNC machining centers, CNC boring machines, surface grinding machines, planers, and other high-precision manufacturing equipment. We have also established an electrostatic spraying production line to further enhance product surface quality and durability. The utilization of robotic welding systems guarantees precise structural joins, which are vital for heavy industrial mill housings operating under continuous vibrational pressure.
Enterprise procurement managers evaluating pea milling systems focus on output parameters, operational stability, and ROI. Achieving optimal protein yield from dry fractionation lines requires specific raw material properties and processing criteria. The table below illustrates the typical technical profile required for yellow field pea processing lines:
| Processing Stage | Core Machinery Involved | Critical Parameters Checked | Industrial Objective |
|---|---|---|---|
| Pre-cleaning & De-stoning | Gravity Destoners, Air Screen Cleaners | Bulk density, Moisture content (12-14%) | Eliminate stones, dust, and pod husks without water consumption. |
| Dehulling & Splitting | Pea Dehullers, Impact Splitters | Hull separation efficiency (>98%) | Remove high-fiber outer skin to prevent protein fraction contamination. |
| Fine Grinding | Fine Jet Mill, Ultra-fine Pin Mill | Particle distribution d50 < 15-20 microns | Dissociate starch granules from protein matrices with low heat. |
| Air Classification | Centrifugal Air Classifier | Cut point adjustments, rotor tip speed | Separate fine protein (18-24% yield) from coarse starch. |
High-yield operations also depend on dust collection and explosion mitigation. Pulse-jet bag filters and ATEX-certified rotary valves are essential safety components when handling ultra-fine organic dusts. Furthermore, integrating energy-saving pneumatic conveying systems ensures that materials are transferred between stages with minimal moisture loss and zero cross-contamination.
Modern plants utilize central SCADA/PLC interfaces. Real-time feed monitoring prevents motor overloading in pin mills, adjusting parameters to process varying seed densities and moisture profiles.
Sensors track motor vibration, roller temperatures, and bearing wear. Automatic alerts prompt pre-emptive adjustments, avoiding unexpected downtime in continuous 24/7 milling runs.
Integrating high-efficiency air classification wheels and low-friction blowers reduces energy usage. Lower heat build-up also preserves the structural integrity of natural proteins.
Our production systems are built for future tech upgrades. In addition to high-purity pea processing, the machines are adaptable to other pulses, such as chickpeas, faba beans, and lentils. This multi-grain flexibility allows processing plants to adjust to changing market demands without investing in entirely new production lines.
