Roots - Maddar
Roots - Maddar
Mechotech designs and manufactures turnkey natural colour extraction plants for madder root (catalogue spelling: Roots - Maddar). In the Mechotech catalogue, Roots - Maddar is listed in the Red Colour group alongside vegetable, hibiscus, avocado, sumac, Brazil wood, St. John’s wort and sycamore entries. Mechotech’s legacy page for the Madder Root (Rubia cordifolia) Colour Extraction Plant describes madder root, known as Manjistha in Ayurveda, as a natural dye source with applications in textiles, cosmetics and herbal medicine, containing anthraquinone compounds, primarily alizarin, which gives a rich red; it lists alizarin (red dye) as used in textile dyeing, natural inks and cosmetics. The legacy page gives no extraction conditions, no assay and no plant capacity, so the route is set during process development. Mechotech’s Red Colour article covers anthocyanins, betalains and carotenoids and does not describe madder.
Mechotech’s Roots - Maddar plant is configured around the raw material and the target colour extract. It is built in SS 316L with integrated solvent recovery, automation and full documentation, and is delivered as a commissioned turnkey system. Because the legacy page states the species, the plant part by name and the principal pigment but no route, the line is specified for solid-liquid extraction, filtration, vacuum concentration and standardisation, and the solvent system, extraction conditions and pH are established during process development and pilot validation on the client’s madder root.
Technical Specifications
| Product | Roots - Maddar Natural Colour Extraction Plant |
|---|---|
| Raw Material | Madder roots (catalogue name: Roots - Maddar; known as Manjistha in Ayurveda per the legacy page) |
| Botanical Name | Rubia cordifolia (per Mechotech’s legacy page for the Madder Root Colour Extraction Plant; the product tree names no species) |
| Plant Part / Feed Form | Roots, as named in the catalogue and the legacy page; cleaned and size-reduced before extraction; exact feed form (fresh or dried, cut or powdered) confirmed with the client |
| Colour Group | Red Colour (see the Red Colour page) |
| Colour-forming Components | Anthraquinone compounds, primarily alizarin (red dye), per the legacy page; the legacy text is cut off after naming purpurin, so no further pigment is stated |
| Process Category | Natural Colour Extraction Plants |
| Extract Type | Natural colour extract (liquid concentrate or dried powder, per specification) |
| Extraction Method | Closed jacketed SS 316L extraction at controlled temperature; solvent system and conditions are not stated in any source and are confirmed during process development |
| Product-contact Material | SS 316L |
| Filtration System | Plate-and-frame filter press with cartridge polish filters |
| Concentration System | Falling-film / vacuum evaporator with solvent recovery where a solvent is used |
| Drying System | Spray or vacuum dryer, where a powder is required |
| 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 | Natural colour extract (red colour group) |
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
Madder root is authenticated, washed free of soil, tested for moisture and size-reduced so the extraction liquor can reach the tissue; the particle size is set during process development.
Extraction
The prepared root is extracted in closed jacketed SS 316L vessels at controlled temperature over several cycles to recover the red anthraquinone pigments. The legacy page states no solvent or temperature, so the solvent system, temperature and pH are set during process development.
Filtration
The extract is separated from the spent root and clarified through a plate-and-frame filter press followed by cartridge polish filters.
Concentration & Solvent Recovery
The extract is concentrated in a falling-film / vacuum evaporator, with solvent recovered through the condenser return system where a solvent is used.
Standardisation
The concentrate is assayed and adjusted to the declared target colour specification, such as shade and colour strength. No assay method or content figure is stated in any source, so the specification is agreed with the client.
Drying & Quality Control
The standardised extract is supplied as a liquid concentrate or spray- or vacuum-dried to a powder, per specification, then released after assay, residual-solvent (where a solvent is used), heavy-metal, microbial and moisture testing.

Key Features
SS 316L Construction
Electropolished SS 316L product-contact surfaces with CIP operation between batches.
Route Set on the Client’s Madder Root
The legacy page names the pigment family but no extraction conditions, so solvent, conditions and shade are established on pilot runs with the client’s material rather than assumed.
Closed-Loop Solvent Recovery
Where a solvent is used, 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, such as shade and colour strength.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
