QIE GROUP delivered a 3000TPD continuous soybean oil solvent extraction project featuring reinforced extractor design, efficient evaporation and solvent recovery, PLC-based intelligent control, and stable 24-hour operation for modern edible oil processing.
The 3000TPD continuous soybean extraction engineering project was developed as a core production unit for a modern edible oil processing facility designed for high-capacity, 24-hour industrial operation. With the client targeting stable throughput, improved soybean oil recovery, lower residual oil in meal, optimized steam and power consumption, higher solvent recovery efficiency, and a stronger safety and environmental management framework, QIE GROUP was selected to provide the extraction system engineering design, equipment manufacturing, and technical support for the project.
Built around continuous solvent extraction technology, the project integrates extraction, evaporation, stripping, solvent condensation, tail gas recovery, and centralized automation into one coordinated process system. The result is a soybean extraction plant configured for stable operation, controlled energy use, and reliable process management under sustained production conditions.
As edible oil processing continues to move toward higher capacity, more integrated production, and stronger operational control, soybean extraction systems are expected to deliver not only throughput, but also long-cycle stability, efficient solvent management, and practical energy performance. For this project, the client planned a 3000TPD soybean extraction workshop as a critical part of its oil processing configuration.
The engineering targets focused on several practical operating requirements:
This soybean solvent extraction project was designed for a processing capacity of 3000 tons per day and operates in a continuous production mode. The system was planned for long-cycle industrial service and includes the main process sections required for closed-loop extraction and solvent handling.
The project configuration includes:
Through this configuration, the plant forms a coordinated process path from extraction to evaporation, condensation, and tail gas recovery, supporting controlled solvent circulation and consistent production management.
To match the operating conditions of a 3000TPD soybean extraction plant, QIE GROUP optimized the main extraction equipment with a reinforced structural design suitable for sustained high-load duty. The extractor configuration was developed to support long-term mechanical stability while maintaining extraction consistency across the full processing width and residence path.
Under stable operating conditions, the residual oil in soybean meal can be controlled at ≤0.5%, while oil recovery performance reaches an advanced level for this type of industrial extraction application.
The mixed oil treatment section adopts a multi-stage evaporation arrangement combined with negative-pressure operation. This design improves concentration efficiency while helping reduce steam demand and unnecessary thermal loss. Multi-stage heat exchangers and waste heat recovery structures are incorporated to make better use of process energy within the extraction line.
Solvent management is one of the most critical parts of any continuous soybean solvent extraction system. In this project, the recovery and protection measures were designed to support safer operation, lower solvent loss, and compliance with modern industrial environmental expectations.
This integrated arrangement helps reduce solvent consumption per ton of material processed while strengthening the overall safety level of the soybean extraction workshop.
The complete extraction line is equipped with a PLC-based centralized control system with touchscreen operation interface. The automation logic supports real-time process visibility and more consistent parameter control across key operating sections.
The project execution scope covered the full engineering and delivery process required for commissioning a continuous soybean extraction unit of this capacity. QIE GROUP participated throughout the implementation cycle under a unified engineering and project management framework, helping coordinate design, manufacturing, installation support, and start-up preparation.
This delivery model reflects QIE GROUP’s practical capability in edible oil processing engineering, including process design, complete equipment manufacturing, intelligent control integration, and on-site technical service for industrial soybean oil projects.
After commissioning, the project achieved the targeted continuous production condition and provided the client with a stable extraction section for soybean oil processing. The operating results highlighted the value of coordinated engineering across equipment structure, thermal design, solvent circulation, and automation.
For the client, this means more than throughput alone. In a high-capacity edible oil plant, extraction performance directly affects downstream refining efficiency, meal quality, solvent cost control, energy management, and the overall operating economics of the facility. A stable extraction system therefore plays a key role in supporting long-term plant performance.
This 3000TPD continuous soybean extraction engineering project demonstrates QIE GROUP’s integrated capability in edible oil processing systems. With more than 40 years of engineering experience, QIE GROUP supports clients worldwide with process design, equipment manufacturing, installation and commissioning support, and intelligent control solutions for soybean, sunflower, rapeseed, peanut, rice bran, palm, corn germ, and other oil-bearing materials.
The project reflects several core capabilities that are essential in industrial soybean extraction plant delivery:
Supported by modern manufacturing facilities, precision machining workshops, assembly areas, and complete line commissioning zones, QIE GROUP applies consistent engineering standards to help clients build soybean extraction systems that are practical, stable, and suited to industrial operating demands.
A 3000TPD continuous soybean solvent extraction project places high demands on process design accuracy, equipment structural reliability, solvent circulation control, energy utilization, and plant-wide operational coordination. In this type of edible oil processing engineering, long-term value is created by the system’s ability to maintain steady production, controllable operating cost, and safe management over time.
This project shows how reinforced extractor design, efficient evaporation and stripping, reliable solvent recovery, and intelligent PLC-based control can work together to support a modern soybean oil processing facility. For companies planning soybean extraction capacity with strong operational continuity and future development potential, this type of engineering approach provides a dependable foundation for sustained production and further process integration.
