Scalability & High Efficiency: A Win-Win for Soybean Protein and Oil
05/26/26

Soybeans contain 18%–22% oil, but their protein content is exceptionally high.

When processing soybeans, the core focus is not mechanical pressing but achieving a high solvent extraction rate while preserving the integrity of the meal protein.

Typical Process Flow

1
Cracking

2
Softening

3
Flaking

4
Expansion (optional)

5
Solvent Extraction

6
Desolventizer-Toaster (DT) with AB vessels

QIE GROUP Advantages

✔ Low Residual Oil Solvent Extraction System

Low Residual Oil Solvent Extraction System – Our proprietary drag-chain or loop extractor design ensures residual oil in the meal drops below 0.5%, maximizing oil recovery and leaving virtually no value behind.

✔ Desolventizer-Toasting Technology

We optimize the desolventizing and cooking process to precisely control heat treatment time based on the intended use of the soybean meal (feed or food-grade protein), effectively protecting protein activity (NSI value).

✔ Energy-Efficient Distillation System

By fully utilizing secondary steam, our entire production line saves 15%–20% energy compared to conventional processes.

“In the industrial landscape of soybeans, QIE GROUP pursues not only the purity of every drop of oil but also the ultimate efficiency of the entire value chain.”
