This palm kernel oil solvent extraction machine manufactured by Henan Glory is specifically designed for large scale palm kernel oil mills with a daily processing capacity of 20 to 600 tons. It efficiently extracts residual oil from pre-pressed palm kernel cake, reducing the residual oil rate to ≤1% through a highly automated process. This maximizes oil yield and revenue while ensuring safe and stable operation.
To ensure safe operation of this high-efficiency palm kernel oil solvent extraction machine, special attention must be paid to the extraction solvent (n-hexane), which is flammable and explosive. Therefore, the extraction workshop must be designed as an explosion-proof facility.
The solvent extraction process is divided into four sections: solvent extraction, desolventizing, miscella evaporation & stripping, and solvent condensation & recovery. Each section is equipped with dedicated professional equipment.
Rotary-type extractor
Structural Design: Composed of inner/outer cylinders and partitions to form 12-24 independent extraction cells. Solvent spray nozzles above extractor spray n-hexane solvent to soak the palm kernel pre-pressed cake.
Design Advantages: Simple structure, reliable operation, and built-in filtration of the fixed material layer, resulting in low foam in the miscella and stable extraction performance. It is suitable for continuous production in medium-to-large palm oil mills.
In addition to the rotary-type extractor, we also provide two extractors for large scale palm kernel oil production lines with a daily processing capacity of several hundred tons:
Loop Type Extractor: Uses a loop-type shell + drag chain structure to flip the material layer, ensuring high extraction uniformity, short processing time, and low residual oil rate.
Drag Chain Extractor: Adopts an integrated box structure with lower equipment height and easier installation. Its residual oil rate can reach 0.6%-0.8%, making it a cost-effective choice for large-scale production lines.
Desolventizer-toaster with integrated dryer-cooler
Structural Design: Features five functional zones: pre-desolventizing layer, desolventizing layer, direct steam layer, hot air layer, and cold air layer.
Design Advantages: It integrates desolventizing, drying, and cooling, with high steam utilization and stable processing performance. The pre-desolventizing layer reduces steam consumption and condensed moisture in the meal; the direct steam layer achieves deep solvent removal by steam penetrating the material layer; the hot air layer reduces meal moisture to below 13%; the cold air layer cools the meal to around 40℃ for storage.
Raising film evaporator and stripping tower
Structural Design: Equipped with two evaporators (using indirect steam) to evaporate part of the solvent. The stripper adopts a falling-film multi-layer structure: miscella enters the tower from the top and flows downward, and indirect/direct steam is used for final solvent removal from the miscella in each layer.
Design Advantages: Stepwise solvent removal via indirect steam evaporation and direct steam stripping ensures high heat exchange efficiency, excellent desolventizing performance, and low oil loss.
Condenser and integrated water separation tank
Structural Design: Equipped with horizontal/vertical condensers (adaptable to different site layouts) and a solvent and water separator (utilizing density differences between solvent and water) to recover solvent vapor generated during miscella evaporation, stripping, meal desolventizing and toasting processes.
Design Advantages: The combination of high-efficiency condensers and water separators achieves high solvent recovery rates, reducing production costs while ensuring production safety and environmental compliance.
In summary, this large scale palm kernel oil solvent extraction plant integrates core advantages such as high efficiency, large processing capacity, and low residual oil rate, which can significantly improve oil yield and economic benefits.
