Sustainable Solutions for the Protein Transition
As the global demand for plant-based nutrition accelerates, manufacturers face the challenge of extracting high-quality protein with maximum yield and purity. KES offers complete system solutions that cover every step of the value chain—from extraction and coagulation to washing and dewatering.
Whether processing starch crops (peas, beans), oilseeds (soy, rapeseed), or leafy crops, our technology platform allows us to develop a customized process for each raw material. Our goal is a holistic concept: ensuring high-quality protein recovery while refining by-products like starch and fibers to minimize waste and optimize value creation.
Visualizing Efficiency: From Raw Material to Isolate
The extraction of plant protein is a multi-stage process requiring precise separation at varying pH levels and temperatures. KES decanters and High Speed Decanters are deployed sequentially to separate fibers, fractionate starch, and isolate protein curd.
Process Breakdown
Extraction
The flour/flakes are mixed with water. KES Decanters separate the fiber and starch solids from the protein-rich liquid phase.
Coagulation
Acid is added to the liquid to precipitate the protein. KES High Speed Decanters (specialized for soft solids) separate the protein curd from the whey.
Washing
To reach high protein purity (isolates), the curd is washed and separated again to remove anti-nutritional factors and salts.
Dewatering
The final protein fraction is dewatered to reduce the thermal load on the spray dryer.
Key Application Areas
Protein from Starch Crops
In the processing of pulses, KES decanters ensure the clean separation of starch and fibers from the protein stream. This allows for the simultaneous production of premium starch and functional protein isolates without cross-contamination.
Protein from Oil Crops
KES provides specialized solutions for recovering protein from oilseed press cakes. For difficult-to-separate materials like Lupin, our high-speed decanters effectively capture fine protein particles that standard machines miss.
Protein from Leaves & Grasses
Unlocking novel sources of protein requires gentle processing. KES equipment is designed to extract protein from leafy biomass while preserving functionality and color.
