Drag chain extractor

The drag chain extractor or towline extractor is a continuous immersion type extractor. The drag chain drags the materials to run for one cycle in the extractor to complete the extraction process.

The transmission structure of a chain extractor consists of three points, that's the driving sprocket wheel, the driven sprocket wheel, and the tension sprocket wheel. Due to the large horizontal distance between the tensioning wheel and the driving wheel, the transmission reliability of the chain and the driving sprocket is formed.

The drag chain extractor is suitable for large-scale oil extraction plants. It is suitable for direct extraction of soybean, rice bran, etc, and pre-pressing extraction of cottonseed, rapeseeds, sesame, camellia seed, tung seed, sunflower seeds, corn germ, grape seed, etc, as well as alcohol extraction of protein.

Drag chain extractor advantages

1. Towline extractor has strong adaptability to raw materials. Especially suitable for oilseeds with high oil content and large fines content, having better extraction effect for common oilseeds.
2. Advanced technology, simple structure, easy operation, low power comsuption, stable and reliable operation, low filture rate.
3. The materials are segmented into several independent units on the bed, effectively prevents various grades of miscella from flowing between the material layers, ensuring the concentration gradient between the percolation segements.
4. Each material cell forms an immersion area, achieving better immersion effect.
5. The materials are fully turned in the towline extractor, good permeability, uniform extraction, low residue oil rate below 0.8%.
