Floral Concrete & Absolute Extraction Plants

Kewada Concrete & Absolute

Mechotech designs and manufactures turnkey floral concrete and absolute extraction plants for kewada (kewda), listed in the Sureka Life Sciences catalogue as Pandanus odorifer. Mechotech’s legacy page describes kewda as a highly aromatic flower with an intense, sweet and fruity fragrance, used in luxury perfumery, cosmetics and aromatherapy. The plant produces a floral concrete by solvent extraction and an absolute by ethanol washing of the concrete. A separate page covers the distillation route to kewada oil.

Mechotech’s kewada plant follows the floral-concrete route: extraction of the flowers with food-grade hexane to a concrete, filtration and quality check, ethanol washing of the concrete to an absolute, then ethanol recovery and concentration. It is built in SS 316L with solvent recovery, PLC-based automation and full documentation, and is delivered as a commissioned turnkey system. Kewada flowers are aromatic and their aroma is perishable, so the line is built around gentle solvent extraction of the flowers to a concrete, vacuum concentration and low-temperature solvent removal. Solvents, temperatures and cycle times are established during process development and pilot validation.

Manufacturing Process

Floral Material Harvesting & Preparation

Kewada flowers are received, inspected and prepared for extraction; handling time and condition are set with the client because flower aroma is perishable.

Hexane Extraction (Concrete Production)

Flowers are extracted with food-grade hexane in closed SS 316L extraction vessels, and the solvent is stripped under vacuum to leave the floral concrete.

Concrete Filtration & Quality Check

The concrete is filtered and checked against the agreed specification before the absolute stage.

Ethanol Washing (Absolute Production)

The concrete is washed with ethanol, which dissolves the aromatic fraction and leaves the waxes largely undissolved.

Ethanol Recovery & Absolute Concentration

The ethanolic solution is filtered, concentrated under vacuum and the ethanol recovered, giving the absolute.

Quality Control & Packaging

The absolute is tested against the client’s specification and packed with batch documentation.

Key Features

Two-Stage Concrete-to-Absolute Route
The line produces a floral concrete first and then an absolute by ethanol washing, so either form can be taken as the finished product.
Gentle Handling of Aromatic Flowers
Gentle solvent extraction to a concrete, vacuum concentration and low-temperature solvent removal protect the floral aroma.
Closed-Loop Solvent Recovery
Hexane and ethanol are recovered through condenser-return systems and reused between batches.
Flammable-Solvent Safety
Solvent-handling areas are specified for flammable solvents; the hazardous-area scope and any certification are confirmed per project.
SS 316L Construction
Product-contact surfaces are SS 316L, with CIP capability between batches.
Scalable Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.

Frequently Asked Questions

Does Mechotech supply the complete machinery for Kewada?

Yes. Mechotech supplies the complete turnkey plant for Kewada — engineered, fabricated at our Hyderabad facility, installed and commissioned as a single integrated system. Final process parameters are established during process development and pilot validation.

What specification can the Kewada plant achieve?

The plant is configured to the client’s target specification for Kewada; the specification achieved is established during process development and pilot validation, and each batch is released with batch-release testing and certificate-of-analysis documentation.

What production capacities are available for the Kewada plant?

Capacity for the Kewada plant is configured to raw-material supply, confirmed buyer volume and investment timeline, starting at pilot scale; a pilot plant is recommended to validate parameters before scaling.

Which industries use the kewada plant?

The end-use areas listed for kewada on this page are given under Applications, as listed by Sureka Life Sciences for Kewada Extract. The end use and the target specification are confirmed with the client before the plant is configured.

Which part and species of kewada are processed?

The catalogue lists kewada (kewda) flowers. The Sureka Life Sciences catalogue names the species Pandanus odorifer, while Mechotech’s legacy page used the name Pandanus odoratissimus. The species and the exact feed form, such as fresh or dried, are confirmed with the client before the plant is configured.

How is kewada absolute produced in the plant?

The flowers are extracted with food-grade hexane in closed SS 316L vessels and the solvent is stripped under vacuum to a floral concrete. The concrete is filtered and checked, washed with ethanol to take up the aromatic fraction, and the ethanolic solution is filtered, concentrated under vacuum and the ethanol recovered to give the absolute, which is tested and packed.

What is the difference between a floral concrete and an absolute?

A concrete is the waxy solvent extract of the flowers. An absolute is made by washing the concrete with ethanol to take up the aromatic fraction and leave most waxes behind. The plant can supply either form.

Which marker does the kewada extract carry?

The Sureka Life Sciences catalogue lists 2-phenylethyl methyl ether (PEM) as the marker compound of kewada extract (floral concrete and absolute route), with a catalogue figure of up to 75.4%. This is a catalogue figure, not a Mechotech guarantee: the level achievable for a given flower supply is established during process development, and the specification is agreed with the buyer.

What is the difference between this Kewada page and the Kewada distillation page?

This page covers solvent extraction of kewada flowers to a floral concrete and absolute. The Kewada distillation plant covers the separate distillation route, which recovers kewada oil by distillation with the hydrosol as a co-product. Choose the route that matches the product you want to make; the Sureka Life Sciences catalogue lists them as separate entries, Kewada Extract and Kewada Distillation.

Which related floral concrete and absolute plants does Mechotech list?

Related pages include Jasmine, Jonquil, Frangipani, Cassie and Tuberose, and the hub Floral Concrete & Absolute Extraction Plants.
