Rotary Extractor

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
Feed Charging
Prepared feed material is loaded into the extraction vessel to begin the extraction cycle.
Solvent Contact
Solvent is introduced to the vessel and contacts the feed material under process-controlled conditions.
Extraction Hold
The feed and solvent are held in contact for the process-defined duration, allowing target compounds to transfer into the solvent phase.
Miscella Drawoff
The solvent-and-extract solution (miscella) is drawn off from the vessel once the batch has reached its target extraction level.
Vessel Discharge
Spent, solvent-wet solids are discharged from the vessel, and the extractor is cleaned in place for the next cycle.

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.
