Rotary Extractor Extraction Equipment — Mechotech

Rotary Extractor

Mechotech engineers and manufactures the Rotary Extractor as turnkey process equipment for pharmaceutical, nutraceutical, food, and botanical extraction lines. Each unit is designed around the client's specific process parameters and target output, then fabricated, installed, and commissioned by Mechotech as a single accountable scope — from engineering drawings through to a performance-verified handover.

The Rotary Extractor is built in SS 316L (or a process-appropriate grade) with electropolished product-contact surfaces and integrated instrumentation, so it can be cleaned in place between batches and operated under PLC-based control. Feed material is loaded into the extraction vessel and contacted with solvent under process-controlled conditions, with the vessel's rotating configuration engineered to the confirmed feedstock and target extraction performance during the design stage rather than fixed in advance. Capacity is configured to the customer's requirement, from pilot-scale systems for process validation to larger commercial installations with modular expansion, and every unit is delivered with full documentation to support GMP and regulatory qualification.

Manufacturing Process

1

Feed Charging

Prepared feed material is loaded into the extraction vessel to begin the extraction cycle.

2

Solvent Contact

Solvent is introduced to the vessel and contacts the feed material under process-controlled conditions.

3

Extraction Hold

The feed and solvent are held in contact for the process-defined duration, allowing target compounds to transfer into the solvent phase.

4

Miscella Drawoff

The solvent-and-extract solution (miscella) is drawn off from the vessel once the batch has reached its target extraction level.

5

Vessel Discharge

Spent, solvent-wet solids are discharged from the vessel, and the extractor is cleaned in place for the next cycle.

Major Plant Equipment

  • Rotary extraction vessel
  • Solvent charging system
  • Miscella drawoff and collection manifold
  • Vessel discharge system
  • CIP skid and spray-ball connections
  • PLC-based control panel

Plant Output

Concentrated miscella (extract-in-solvent)Discharged spent solids

Applications

  • Pharmaceutical and nutraceutical process manufacturing
  • Botanical and herbal extraction industries
  • Food and flavour processing
  • Export to regulated-market equipment buyers

Key Features

  • GMP-Compliant Construction

    Electropolished product-contact surfaces meet WHO-GMP and Schedule M requirements, and the vessel is cleaned in place (CIP) between batches without manual disassembly.

  • Turnkey Engineering

    Design, fabrication, installation, and commissioning are delivered as one accountable scope, so the client deals with a single engineering team from drawing to handover.

  • Scalable Capacity

    The extractor is sized to the customer's requirement, from pilot-scale validation through to commercial capacity, with modular expansion as production grows.

Frequently Asked Questions

Does Mechotech supply the complete Rotary Extractor?
Yes. Mechotech is a process equipment manufacturer and supplier, engineering and fabricating the complete Rotary Extractor at our Hyderabad facility, installing and commissioning it as a single performance-verified system.
What capacities are available for the Rotary Extractor?
Mechotech builds the Rotary Extractor from pilot systems for product development to larger commercial capacities. Capacity is selected based on feedstock/throughput requirements, confirmed buyer volume, and investment timeline; we recommend a pilot system to validate parameters before scaling.
Which industries use the Rotary Extractor?
Pharmaceutical, nutraceutical, food, and botanical-extraction manufacturers across India and export markets use Mechotech equipment for consistent, compliant production.
How is the Rotary Extractor configured for a specific feedstock?
Mechotech's process engineers size and configure the vessel around the client's feedstock, batch size, and target output specification during the engineering stage, with exact rotational and process parameters confirmed as part of that design work rather than fixed for every application.
