Tuberose
Tuberose
Mechotech designs and manufactures turnkey floral concrete & absolute extraction plants for Tuberose. The product tree lists the entry as Tuberose under Floral Concrete & Absolute Extraction Plants, and Mechotech’s legacy page for the Tuberose Concrete & Absolute Extraction Plant describes cold food-grade hexane maceration of tuberose (Polianthes tuberosa, rajnigandha) flowers followed by ethanol washing, with benzyl alcohol, benzyl benzoate, methyl benzoate and farnesol named as the defining compounds of the absolute. The Sureka Life Sciences (SLS) catalogue lists a Tuberose Extract with Polianthes tuberosa as the botanical source and a 9–30% methyl benzoate offering grade. This page is the solvent-extraction route; the distillation route is on the Tube Rose page. The exact flower form is confirmed with the client before the plant is configured.
Mechotech’s Tuberose plant is configured around the raw material and the target extract. It is built in SS 316L with integrated solvent recovery, automation and full documentation, and is delivered as a commissioned turnkey system. Mechotech’s legacy page describes cold maceration in food-grade hexane, filtration of the miscella, vacuum evaporation to a concrete, washing of the concrete with ethanol, and chilling and recovery of the absolute. The solvent, conditions and the concrete or absolute grade for a given project are established during process development and pilot validation.

| Product-contact Material | SS 316L |
| Filtration | Plate-and-frame filter press with cartridge polish filters |
| Concentration | Falling-film / vacuum evaporator with solvent recovery |
| Drying / Finishing | Vacuum evaporation to concrete at low temperature; ethanol washing, chilling and wax filtration to an absolute |
| Automation | PLC-based |
| Plant Capacity | Configured to requirement |
| Utility Requirements | Steam, chilled/cooling water, compressed air and power (project-specific) |
| Compliance | GMP hygienic design; full documentation for qualification |
| Final Product Form | Tuberose concrete or tuberose absolute, per specification |
Plant Capacities
| Plant Scale | Raw Material Throughput | Typical Use |
|---|---|---|
| Pilot | Configured to your feedstock and trial plan | Product development, parameter validation |
| Semi-Commercial | Configured between pilot and commercial scale | Scale-up trials, contract manufacturing |
| Commercial | Configured to raw-material supply and confirmed buyer volume | Commercial production |
Capacity is configured to raw-material supply, confirmed buyer volume and investment timeline; a pilot plant is recommended to validate parameters before scaling.
Manufacturing Process
Raw Material Preparation
Fresh tuberose flowers are collected and inspected on receipt, then sorted and cleaned of stalks and debris; the legacy page treats the flowers as fresh material, so the time between picking and extraction and the handling are set with the client.
Extraction
The flowers are macerated in cold food-grade hexane in closed jacketed SS 316L vessels, which dissolves the aromatic compounds together with natural plant waxes. The solvent, the contact time and the temperature are set during process development.
Filtration
The extract (miscella) is clarified through a plate-and-frame filter press followed by cartridge polish filters.
Concentration & Solvent Recovery
The miscella is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system.
Standardisation
The legacy page’s steps continue with miscella filtration, vacuum evaporation to a concrete and ethanol washing of the concrete to an absolute; the concentrate is assayed and adjusted to the client’s target specification, with methyl benzoate as the catalogue marker, before final finishing.
Finishing & Quality Control
The ethanol solution is chilled and filtered to remove precipitated waxes, and the ethanol is stripped and recovered to leave the absolute. Each batch is sampled for GC-MS profile and physical parameters against the client’s specification before release.

Key Features
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Alcohol / Aqueous Solvent Extraction
Closed jacketed extractors run food-grade alcohol or aqueous solvent over multiple cycles to recover the target fraction.
Closed-Loop Solvent Recovery
Integrated condenser-return recovery reuses solvent between batches and reduces solvent loss.
Standardised to Specification
In-process and batch-release assay are used to check the finished extract against the agreed target specification.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
