For international investors, setting up a soybean oil production line is not just about buying machinery; it is about engineering a system that balances oil yield, energy efficiency, and byproduct value. At QIE Group, we provide full turnkey solutions that transform raw soybeans into premium edible oil and high-value soybean meal through optimized, automated processes.

1. Pre-treatment: Building the Foundation for High Oil Yield

The success of your soybean oil processing plant begins in the pre-treatment section. The goal here is to prepare the soybean's cellular structure for maximum oil release.

• Cleaning & De-stoning: Utilizing high-efficiency cleaning screens and magnetic separators, QIE Group systems remove impurities.
• Cracking & De-hulling: Separating the hull increases protein concentration in soybean meal, directly enhancing your ROI.
• The Decision Point — Flaking vs. Expanding:
  • Flaking: Mechanical destruction (≤0.3mm) to avoid protein denaturation.
  • Expanding: High-pressure porous "colloid" formation to increase extraction efficiency and capacity.

2. Advanced Extraction: Deep Oil Recovery

For small to large scale operations, solvent extraction is the industry standard for achieving a residual oil rate of ≤ 0.5%.

Utilizing the DTDC Desolventizer-Toaster, our system toasts the meal to destroy anti-nutritional factors, making it perfect for animal feed or soy sauce production.

3. Refining: Achieving International Edible Standards

The "crude oil" must be purified to become a safe, stable product. QIE Group’s refining lines support both physical and chemical methods.

4. Why a "Turnkey" Approach Wins

As a reliable soybean oil machinery supplier from China, QIE Group ensures:

• ✅ Seamless Integration: Matching steam and power requirements across sections.
• ✅ Maximized ROI: Reducing energy consumption by 10-15% via heat recovery.
• ✅ Global Installation: On-site engineering support for 24/7 reliability.
