High-volume oilseed extraction system
Achieve optimal extraction efficiencies with a versatile system that handles various materials, from vegetable proteins to specialty chemicals, ensuring minimal solvent usage and consistent quality in every batch.

Extracts and Processes High-Volume Plant-Based Materials
The Model III Percolation Extractor from Crown Iron Works is engineered for continuous high-volume extraction of various plant-based materials, including oilseeds, hemp, and specialty chemicals. Utilizing a continuous-loop, counter-current design, this extractor facilitates efficient solvent contact and drainage, ensuring optimal extraction from various inputs such as vegetable proteins, producing high-quality outputs like soy protein isolate and biodiesel.
This extractor features a wide, shallow flake bed which enhances solvent percolation and contact efficiency, making it ideal for applications requiring high throughput and consistent product quality. Its processing capacity effectively supports large-scale operations across industries like nutraceuticals and biofuel production.
The equipment is PLC-controlled for seamless integration into your production line, minimizing energy consumption by optimizing motor speed and solvent use. Maintenance is simplified through self-cleaning drainage screens and easy-to-clean flake discharge systems. Additionally, its scalable design allows for customization and expansion, backed by robust engineering support from Crown Iron Works.
