Industrial Extractor
High-capacity continuous solvent extraction systems engineered to maximize oil yield and minimize solvent loss in edible oil plants.
Maximizing Yield.
Preventing Losses.
In solvent extraction, every drop of oil left in the meal and every vapor of hexane lost impacts your profitability. Our extractors are built to push residual oil down to < 1% safely and efficiently.
Counter-Current Extraction
Our extractors utilize a highly efficient multi-stage, counter-current washing process. Pure solvent meets the leanest seed cake at the discharge end, ensuring maximum penetration and deep extraction of the last remaining oil molecules.
Vapor-Tight Operational Safety
Hexane is highly volatile. Our extractor casings are precision-welded and structurally reinforced to operate under slight negative pressure, guaranteeing zero solvent vapor leaks into the factory atmosphere.
Integrated sight glasses and explosion-proof (ATEX) lighting allow operators to safely monitor the internal miscella flow and percolation rate in real-time.
Flagship Equipment
Continuous Extractor
Deep Bed Extraction
The key to a high-yield extraction is maintaining the perfect bed height of the prepared seed/cake. Our extractors feature an adjustable speed drive that allows operators to tune the residence time precisely based on the material's porosity.
High-volume miscella circulation pumps spray the solvent evenly over the bed, ensuring thorough penetration without flooding the compartments.

Heavy-Duty Structural Integrity
Continuous extractors handle massive loads of saturated meal. The main casing and hoppers are fabricated from heavy-gauge mild steel or stainless steel, braced with structural ribs to eliminate flexing or vibration.
The internal chain and sprocket mechanism is forged from high-tensile alloy steel, engineered to pull the heavy bed of material smoothly 24/7 without snapping or stretching.
Operational Capabilities
Proven Extraction Efficiency
Extracts maximum oil, leaving less than 1% residual oil in the discharged meal.
Built for massive scale continuous processing in global oil seed plants.
Negative pressure design ensures completely leak-free hexane processing.
Technical Specifications
Engineered Features
The extraction bed is supported by highly durable, self-cleaning stainless steel wedge wire screens, preventing blinding and ensuring flawless miscella percolation.
The main chain drive is controlled by an advanced VFD, allowing operators to instantly adjust the bed speed and residence time depending on the raw material being processed.
Equipped with a series of high-capacity centrifugal pumps that continuously recirculate the miscella over the seed bed, ensuring maximum solvent saturation and washing.
The feed hopper is equipped with smart level sensors that automatically control the rotary valve, maintaining a perfect vapor seal and consistent material input.
Forged alloy steel chains and precision-machined sprockets ensure the internal band moves massive tonnage flawlessly without stretching, breaking, or jamming.
Multiple ATEX-certified illuminated sight glasses are strategically placed along the casing, allowing operators to safely monitor the extraction sprays and bed movement.
Implementation Protocol
How We Work
Our engineering teams design every extractor to match your specific seed prep capacity, ensuring perfect percolation and maximum oil recovery.
Feed Analysis
We evaluate the porosity, flaking thickness, and oil content of your prepared seed cake to determine the precise length and bed depth required for the extractor.
Flow & Residence Design
Our engineers calculate the optimum solvent-to-meal ratio, designing the multi-stage spray zones to guarantee optimal counter-current washing without flooding.
Fabrication & Hydro-Testing
The casing is welded, thoroughly leak-tested, and assembled with the heavy-duty drive chain. Once cleared, it is shipped and integrated into your extraction plant.
Setting the Benchmark in Solvent Extraction
In the edible oil industry, leaving even 1% extra oil in the meal costs millions over time. We engineer precise, robust extractors that ensure you extract every possible drop while keeping your hexane consumption remarkably low.
Maximum Oil Yield
Achieves exceptional extraction efficiency, reliably dropping residual oil in the discharged meal to < 1%.
Zero Hexane Loss
Fully welded, vapor-tight casing operates under negative pressure to completely eliminate solvent vapor leaks.
Unbreakable Drive
Forged alloy chains and sprockets designed to pull massive tonnage 24/7 without stretching or snapping.
High Miscella Clarity
Self-cleaning wedge wire screens ensure the pumped miscella is clear, reducing the load on your distillation section.

Industry Testimonials
"Before installing this continuous extractor, we were struggling with high residual oil and constant chain stretching issues. Upgrading to this system solved both immediately. Our residual oil dropped to consistently below 1%, and the heavy-duty drive hasn't required adjustment in 18 months."

Frequently Asked Questions
The extractor is highly versatile. Assuming proper seed preparation (flaking/expanding), it can process Soybean, Sunflower, Rapeseed/Canola, Cottonseed, Groundnut, and Rice Bran.
It's a process where the fresh, pure solvent enters at the discharge end (where the meal has the least oil), and flows backward against the material flow. This guarantees maximum oil extraction efficiency.
The entire main casing is heavily welded and pressure-tested. Additionally, the system operates under a slight negative pressure, meaning if a seal were ever compromised, air gets pulled in, rather than hexane leaking out.
We manufacture custom extractors ranging from 50 Tons Per Day (TPD) for boutique or specialized operations, all the way up to massive 1500+ TPD continuous plants.
The main drive motor is connected to a Variable Frequency Drive (VFD). This allows the operator to instantly speed up or slow down the internal band, perfectly tuning the residence (extraction) time.
We use heavy-duty stainless steel wedge wire screens. Their unique V-shaped profile makes them self-cleaning, preventing fine meal particles from blinding the screen and halting percolation.
Absolutely. The main pulling chains and sprockets are forged from high-tensile alloy steel. They are designed to withstand continuous pulling force without stretching, minimizing maintenance.
The extractor features an automated feed hopper equipped with capacitive level sensors. It controls a rotary airlock valve, ensuring a continuous plug of material that seals the entrance from vapor leaks.
Large, toughened sight glasses are installed along the side of the casing, complete with ATEX-certified explosion-proof illumination lamps so operators can visually confirm the spray pattern.
Given the large structural scale and precision welding required, a standard continuous extractor typically takes 8 to 12 weeks to fabricate, test, and prepare for dispatch.
