Soybean Oil Solvent Extraction Equipment | High Oil Yield and Low Energy Consumption Solution

Can the solvent extraction process for soybean oil be made even more efficient? Let's hear how QIE Group does it.

In soybean oil production, many people only focus on pressing efficiency. However, the key step that truly determines oil yield and quality is often overlooked – the solvent extraction process. Don't underestimate this step; it directly impacts the quality of the final oil, energy consumption, and overall cost. A properly optimized extraction system can yield an extra 1-2 kilograms of oil per ton of soybeans, resulting in a difference in profits of hundreds of thousands or even millions of yuan per year. 👉 Further Reading: [ Which is more profitable, solvent extraction or pressing for soybean oil? ]

Why is solvent leaching considered a "hidden champion"?

Under traditional processes, many oil plants still use old-fashioned solvent leaching tanks, relying on manual experience to control solvent concentration and temperature. This not only results in large fluctuations and poor stability, but also frequently causes safety hazards due to improper operation.

Professional suppliers like QIE Group have long incorporated intelligent and energy-saving concepts into their designs. They don't simply replace equipment; they redefine the logic of the entire leaching process: from material flow and heat recovery to safety protection, every detail has been repeatedly verified.

Three core advantages ensure that solvent extraction is no longer a hindrance.

Intelligent design makes production more efficient and stable.

Traditional solvent extraction equipment often suffers from drawbacks such as complex operation, high energy consumption, and difficult maintenance. Our fully automatic soybean oil solvent extraction equipment, through a PLC intelligent control system and a central monitoring platform, achieves full automation of the entire process from feeding, solvent extraction, desolventizing, evaporation to solvent recovery.

• 1️⃣ The interface is available in both Chinese and English , supporting multilingual switching for the convenience of international users;

• 2️⃣ Local control buttons and automatic interlocking procedures ensure operational safety;

• 3️⃣ Automatic alarm and trend recording system for real-time monitoring of operational status;

• 4️⃣ Two operators can complete the entire production line , significantly reducing labor costs.

This system greatly simplifies the process while maintaining high equipment stability and high oil yield. 👉 Further Reading: [ How to Improve Soybean Oil Extraction Rate? ]

Highly reliable structural design reduces downtime and maintenance time.

We are well aware of the demands that continuous production places on equipment durability and maintainability. Therefore, we have comprehensively optimized the details of the mechanical structure:

• 1️⃣ External bearing design avoids solvent corrosion and extends service life;

• 2️⃣ The scraper chain has been upgraded for wear resistance , ensuring smooth material conveying;

• 3️⃣ Hardened gear reducer and quick-opening hand hole structure make maintenance faster;

• 4️⃣ The lifting lug structure facilitates the hoisting and replacement of large components;

• 5️⃣ Leak-proof sealing system to ensure workshop safety and solvent recovery rate.

These improvements make the equipment more stable in long-term operation, extend maintenance cycles, and significantly reduce unexpected downtime.

Energy-saving and environmentally friendly, creating a low-energy production line

With rising energy prices and increasingly stringent environmental policies, energy conservation and emission reduction have become crucial for oil refineries' competitiveness. Our intelligent solvent leaching system is based on "low feed-to-solvent ratio, high-efficiency mass transfer, negative pressure evaporation, and waste heat recovery."

• 1️⃣ Low solvent ratio process : Reduces solvent usage while maintaining oil yield;

• 2️⃣ Multi-stage negative pressure evaporation system : significantly reduces steam consumption;

• 3️⃣ Oil-to-oil and solvent heat exchange design : recovering and reusing waste heat;

• 4️⃣ Solvent recycling and purification system : Improves recovery rate and reduces emission risks.

In practical applications, the system's overall energy-saving rate can reach 15%–20%, which not only reduces operating costs but also meets international environmental protection standards.

Global Success Stories | Practical Applications of Intelligent Solvent Leaching Systems

QIE Group's intelligent solvent leaching equipment has been successfully operating in several countries, including Egypt, Indonesia, Nigeria, and Uzbekistan.

For example, in the 30-ton/day soybean oil production line project in Egypt, through the low material-to-solvent ratio design and multi-stage heat recovery system, the oil plant's overall energy consumption was reduced by about 18% compared to traditional solvent leaching equipment, solvent consumption was reduced by nearly 20%, and the equipment uptime exceeded 95%.

Similar results have been validated in many parts of Southeast Asia and Africa, providing replicable smart energy-saving solutions for oil plants worldwide.

Safety protection, safeguarding production operations in all aspects

Safety is always the top priority in the design of QIE Group's equipment. The system is equipped with multiple protection and automatic monitoring modules:

• 1️⃣ Overload protection and shaft monitoring device

• 2️⃣ Combustible Gas Detection and Alarm System

• 3️⃣ Emergency Interlock and Automatic Shutdown Procedures

• 4️⃣ High Temperature and Pressure Multi-point Sensing System

These intelligent protections ensure that the equipment can continue to produce stably in a safe and controlled environment, even under high load.
