The Rotocel Extractor is one of the most widely used continuous solvent extraction equipment in the edible oil industry. Designed with a circular structure and multiple material cells, it allows raw materials to rotate along with the main body while being sprayed with solvent. This ensures full contact between oilseed materials and solvent, achieving highly efficient oil extraction.

As a key machine in large-scale edible oil production lines, the rotocel extractor is mainly applied after oilseed pretreatment and flaking. It is particularly suitable for materials with low oil content or those that require solvent extraction to maximize oil yield.

Technical Features of Rotocel Extractor

Circular structure with multiple extraction cells, ensuring continuous and efficient immersion.

Equipped with advanced material inlet and outlet devices, guaranteeing uniform material distribution.

Solvent spraying system ensures effective washing of oilseed flakes.

Robust sealing system reduces solvent loss and improves working safety.

Designed for easy maintenance and long service life.

Product Advantages

High Oil Extraction Efficiency – Ensures low residual oil content in meal, improving profitability of the oil plant.

Stable Operation – The rotating cell design and continuous working principle guarantee reliable performance in long-term production.

Energy Saving – Optimized solvent spraying and circulation system reduces solvent consumption.

Flexible Capacity – Can be designed to handle different processing scales, from medium-sized plants to large industrial oil mills.

Safe and Environment-Friendly – Closed structure minimizes solvent leakage, reducing environmental impact and ensuring operator safety.

Applications in Oil Extraction Process

The rotocel extractor is used in the solvent extraction process, where it separates oil from pretreated oilseeds or cakes through immersion and spraying. It is widely applied for oil-bearing materials such as soybean, rapeseed, cottonseed, sunflower seed, peanut, corn germ, rice bran, and other oilseeds.

This equipment is essential in modern edible oil processing plants, where mechanical pressing alone cannot achieve the desired oil recovery. By combining pressing and solvent extraction, oil mills can reach higher extraction rates, reduce residual oil in meal, and improve overall economic benefits.
