50 TPD Peanut Oil Pressing Production Line Project

Located in Africa, this project features a 50 TPD peanut oil pressing line, with QIE Group responsible for overall process planning and equipment integration. The project adopts an integrated solution covering mechanical pressing, small-scale continuous refining, and finished product filling. It includes key stages such as peanut pretreatment, pressing, refining, oil storage, and filling, helping the customer establish a stable and sustainable peanut oil processing system.

This project is positioned as a complete edible oil processing plant. Based on local raw material conditions, energy availability, and production requirements, QIE Group carried out integrated planning for peanut pretreatment, mechanical pressing, refining, oil storage, and filling. The project not only enables raw material pressing but also establishes an industrial production system from peanuts to finished edible oil, while reserving capacity for future output optimization and process upgrades.

1. Processes 50 tons of peanut raw materials per day to meet basic industrial production requirements.

2. Maintains stable oil yield performance and product quality, improving production planning predictability.

3. Includes basic refining and filling capabilities to establish a complete finished oil production chain.

4. Reduces operating costs and maintenance complexity while adapting to local production conditions.

5. Improves production continuity and reduces excessive reliance on operator experience.

Mechanical pressing + small-scale continuous refining + finished product filling integrated solution

Based on the characteristics of peanut raw materials and the implementation conditions at the project site, the project adopts a proven, controllable, and easy-to-manage process route. It is suitable for peanuts with high oil content, ensuring process stability while controlling system complexity.

• Mature process technology, facilitating on-site commissioning and long-term operation;

• No solvent system required, providing a clearer overall investment structure;

• Suitable for localized operation and subsequent maintenance;

• Offers a certain level of scalability to support future production line upgrades.

Fluctuations in raw material moisture content and impurities:These factors may affect pressing stability and subsequent oil quality control; therefore, proper cleaning, crushing, and conditioning processes are required.

Local energy supply conditions:The boiler, thermal energy system, and production schedule need to be properly matched to ensure the operation of key processes.

Operator experience:The process design should facilitate training and implementation, reducing excessive dependence on individual operator experience.

Continuous and stable production:The pretreatment, pressing, refining, and storage and transportation systems need to remain well connected and coordinated.

Pretreatment system optimization:A cleaning, destoning, magnetic separation, crushing, and conditioning system is configured to improve peanut raw material uniformity and reduce the impact of impurities and raw material fluctuations on the pressing process.

Two-stage pressing process:A pre-pressing and second pressing configuration is adopted to improve oil extraction efficiency and reduce residual oil in the cake while maintaining a controlled operating rhythm.

Refining system configuration:Basic refining processes, including degumming, deacidification, bleaching, and deodorization, are configured to improve crude oil quality and meet finished edible oil processing requirements.

Auxiliary system integration:The boiler heating system, oil storage system, automatic filling line, and laboratory testing equipment are incorporated into the overall solution to improve the completeness of plant operations.

Residual Oil in Cake:≤5–6%

Crude Oil Impurities:≤0.2%

Moisture Content:≤0.2%

This 50 TPD peanut oil pressing production line project in Africa involved more than the delivery of equipment. It helped the customer establish a complete production chain covering peanut raw material handling, mechanical pressing, refining, and finished product filling. Based on local production conditions, the project integrated the planning of process technology, equipment, and auxiliary systems, providing a foundation for the industrial utilization of local peanut resources. For businesses planning to build a peanut oil production line, peanut oil processing project, or turnkey edible oil processing plant, this project demonstrates the importance of systematic process design and equipment integration. Leveraging its grain and oil machinery R&D, manufacturing, and engineering delivery capabilities, QIE Group provides global customers with edible oil processing solutions tailored to different raw materials, capacities, and project conditions.
