An Edible Oil Extractor is central to a Solvent Oil Extraction Plant for Edible Oil. Its role: separate oil from various oil‑bearing materials (e.g. pre-pressed cake, flakes) using a solvent like n‑hexane.
Through controlled contact between solvent and raw material, it yields a miscella (oil + solvent) and residual “wet meal.”
This process dramatically lowers residual oil in the meal — often under 1%.
Working Principle: How It Extracts Oil
1. Feeding: By the oil pretreated a oil material (flakes or pre‑pressed cake) is continuously fed into the extractor.
2. Spraying / Soaking: The solvent is sprayed on the material or the material is immersed.
3. Circulation: The miscella (oil + solvent) circulates.
4. Separation: After extraction, two products come out:
- Wet meal: Extracted residue, still containing solvent. It’s sent to a desolventizer to remove solvent.
- Miscella: Sent to an evaporation system, where solvent is separated (via distillation) from oil. The solvent is then condensed and recycled.
Main Types of Extractors
There are several types of edible oil extractors, but three are especially common: Rotocel extractor, Loop type extractor, and less commonly Ballyuan extractor (or chain/towline types).
Rotocel Extractor
1. Structure: cylindrical shell, internal rotor with multiple “cells,” drive system inside.
2. Operation: material cells rotate; each cell undergoes spray‑soak‑drain‑wash cycles.
Loop Type Extractor
1. Structure: long loop, uses a drag chain conveyor to rotate material slowly.
2. Operation: materials flip in the bend section, enabling uniform contact.
Ballyuan Extractor / Towline / Chain Extractor
1. This type is often used in very large oil refinfing plant, especially for high‑oil-content cakes or fine materials.
2. Operation: continuous immersion; material is dragged by chain through the extractor, each unit forming its own “cell.”
Comparing Rotocel, Loop & Ballyuan Extractors
| Criterion | Rotocel | Loop Type | Ballyuan / Chain |
|---|---|---|---|
| Best for Scale | 30–300 t/day | >500 t/day | Very large, continuous plants |
| Extraction Mode | Combined (immersion + percolation) | Primarily percolation | Immersion with multiple cells |
| Energy Use | Low rpm, gear‑rack drive | Low chain speed, efficient circulation | Efficient for bulk |
| Residual Oil | <1% typical | <1% when properly designed | <1% when properly designed |
| Maintenance | Simple structure, easy maintain | Moderate, chain wear to manage | Higher complexity, more wear points |

Q1: What is the difference between a Rotocel Extractor and a Loop Type Extractor?
A: The Rotocel Extractor uses rotating compartments to extract oil, while the Loop Type Extractor uses a continuous conveyor loop for more efficient large-scale operations.
Q2: How do I maintain my Edible Oil Extractor?
A: Regular maintenance includes cleaning, checking for wear on the rollers and seals, and ensuring the solvent recovery system is functioning properly.
Q3: Can the Edible Oil Extractor be used for all types of oilseeds?
A: Yes, but certain models may be better suited for specific oilseeds. Consult with us to select the right model for your raw materials.
