Batch Extractor
Rugged Batch Type Solvent Extractor systems built for reliable, high-yield oil extraction in small and medium scale plants.
Introduction
Super Techno Engineers is a trusted Batch Extractor Manufacturer serving edible oil plants across India. Not every plant needs a large, fully continuous extraction line. Many small and medium scale producers need equipment that is simple to operate, easy to maintain, and still delivers efficient oil recovery. This is exactly the gap our Batch Extractor fills, giving you dependable extraction performance without the complexity and cost of a large continuous system.
As a specialist Batch Extractor Manufacturer in India, we design our units as a proven Batch Type Solvent Extractor suited for a wide range of oilseeds and oil cakes. Whether you are setting up a Batch Extractor for Small Scale Plant operation or looking for dependable Batch Solvent Extraction Equipment to add flexibility to your existing setup, Super Techno Engineers builds a Batch Extractor for Oilseeds that is engineered for consistent, repeatable results, batch after batch.
Multi-Stage Soaking and Draining Design
A batch extractor works differently from a continuous moving-bed system. Instead of material flowing through the equipment while solvent is sprayed on it, the prepared seed or cake is loaded into the vessel as one batch, then soaked in solvent, drained, and soaked again across several stages until the oil content is reduced to the target level.
Our Batch Type Solvent Extractor uses a perforated false bottom that supports the material bed while allowing miscella to drain freely into the collection chamber below. A dedicated circulation pump then recirculates fresh solvent or weaker miscella over the bed for each soaking stage, following a counter-current pattern so that the freshest solvent contacts the most extracted material at the final stage, maximizing oil recovery.
Because the entire cycle happens within one sealed vessel, the extractor maintains a tight vapor seal throughout the soaking, draining, and solvent recovery stages, keeping hexane loss to a minimum even though the process runs in batches rather than continuously.

Heavy-Duty Structural Integrity
Every Batch Extractor handles a full load of saturated seed or cake in each cycle, and the vessel has to hold this weight securely while staying vapor-tight. The main vessel, false bottom, and access doors are fabricated from heavy-gauge mild steel or stainless steel, braced to prevent flexing under load or vibration during operation.
The circulation pump, piping, and drain valves are built from corrosion-resistant material suited for continuous hexane contact, ensuring the extractor holds up to repeated soak and drain cycles without leaks developing at the joints over time.
Access doors and seals are designed for easy opening between batches while maintaining a reliable vapor seal once closed, so operators can load and unload the vessel quickly without compromising safety.
Why a Batch Extractor Suits Smaller Plants
A Batch Extractor for Small Scale Plant operation offers a different set of advantages compared to a large continuous line, and these matter a lot depending on your production volume:
Lower Initial Investment
A batch system requires less structural steel, fewer moving parts, and a smaller footprint than a continuous extraction line, making it a practical entry point for smaller producers.
Simple Operation and Maintenance
With no long chain-driven conveying system to maintain, a Batch Solvent Extraction Equipment setup is easier for a smaller technical team to operate and service reliably.
Flexibility Across Materials
A Batch Extractor for Oilseeds can be adjusted more easily for different seed types and batch sizes, which suits plants that process a variety of raw materials rather than one fixed feedstock at high volume.
For producers planning to scale up in stages, a batch extractor is also a practical way to start extraction operations before committing to the higher investment of a continuous plant.

Technical Specifications
Engineered Features
Supports the material bed while allowing miscella to drain freely into the collection chamber below, ensuring even drainage across the entire bed in every cycle.
Dedicated circulation pump recirculates fresh solvent or weaker miscella over the bed across multiple soaking stages, so the freshest solvent contacts the most extracted material at the final stage, maximizing oil recovery.
Entire soak, drain, and solvent recovery cycle happens within one sealed vessel, maintaining a tight vapor seal throughout and keeping hexane loss to a minimum even in batch operation.
Main vessel, false bottom, and access doors are fabricated from heavy-gauge Mild Steel or Stainless Steel, braced to prevent flexing under load or vibration during operation.
Circulation pump, piping, and drain valves are built from corrosion-resistant material suited for continuous hexane contact, holding up to repeated soak and drain cycles without leaks developing at the joints.
Access doors and seals are designed for easy opening between batches while maintaining a reliable vapor seal once closed, letting operators load and unload quickly without compromising safety.

Implementation Protocol
How We Work
As a leading Batch Extractor Manufacturer in India, our engineering teams design every unit to match your seed type, batch size, and target oil recovery, ensuring efficient and reliable extraction cycle after cycle.
Feed Analysis
We evaluate the type of oilseed or cake you process, along with your desired batch size, to determine the correct vessel size and false bottom design.
Soak Cycle Design
Our engineers calculate the number of soaking stages and solvent circulation rate needed to achieve your target residual oil level for the specific material being processed.
Fabrication & Leak-Testing
The vessel, false bottom, and piping are welded, thoroughly leak-tested, and assembled with the circulation pump and drain system. Once cleared, it is shipped and integrated into your plant.

Frequently Asked Questions
A Batch Extractor processes one load of material at a time through several soaking and draining stages within a single vessel, while a continuous extractor moves material through the equipment on a moving bed. Batch systems are simpler and suit smaller production volumes.
Yes. A Batch Extractor for Small Scale Plant operation is a practical choice for smaller producers because it needs a smaller footprint, less structural steel, and a simpler technical team to operate compared to a continuous system.
Yes. We size the vessel, false bottom design, and soaking cycle based on the specific oilseed or oil cake you process and your target batch size.
The main vessel, false bottom, and access doors are usually built from Mild Steel or Stainless Steel (SS 304), chosen based on your process requirement and hygiene needs.
With a properly designed multi-stage soak and drain cycle, our Batch Solvent Extraction Equipment typically achieves residual oil levels below 1.5% in the spent material, depending on the seed type and cycle time used.
The extraction takes place inside a sealed vessel that maintains a slight negative pressure throughout the soaking, draining, and solvent recovery stages. This keeps hexane vapor contained even though loading and unloading happen between batches.
