Osmanthus Floral Concrete & Absolute Extraction Plants — Mechotech

Osmanthus

Mechotech designs and manufactures turnkey floral concrete and absolute extraction plants for osmanthus (Osmanthus fragrans). The product tree lists the feed as flowers and blossoms, and Mechotech’s legacy page presents osmanthus as one of the most elegant and alluring floral essences amid growing demand for luxurious floral absolutes. The plant produces a floral concrete by hexane extraction and an absolute by ethanol washing of the concrete. The Sureka Life Sciences catalogue entry for Osmanthus Extract is internally inconsistent about its marker, so no marker is stated on this page.

Mechotech’s osmanthus 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. Solvents, temperatures and cycle times are established during process development and pilot validation.

Manufacturing Process

1

Floral Material Harvesting & Preparation

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

2

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.

3

Concrete Filtration & Quality Check

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

4

Ethanol Washing (Absolute Production)

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

5

Ethanol Recovery & Absolute Concentration

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

6

Quality Control & Packaging

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

From Plant to Product

Osmanthus Extract

This botanical is also in the product range of Sureka Life Sciences, our sister concern in botanical ingredients.

Applications

  • High-end perfumery
  • Skin-care formulations
  • Aromatherapy and massage products
  • Natural soaps and candles
  • Culinary uses (limited)

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 Delicate Blossoms

    Gentle solvent extraction to a concrete, vacuum concentration and low-temperature solvent removal protect the delicate 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 Osmanthus?
Yes. Mechotech supplies the complete turnkey plant for Osmanthus — 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 Osmanthus plant achieve?
The plant is configured to the client’s target specification for Osmanthus; 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 Osmanthus plant?
Capacity for the Osmanthus 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 osmanthus plant?
The end-use areas listed for osmanthus on this page are given under Applications, as listed by Sureka Life Sciences for Osmanthus Extract. The end use and the target specification are confirmed with the client before the plant is configured.
Which part of osmanthus is processed?
The product tree lists Osmanthus (Flowers / Blossoms). The exact form, such as fresh or dried blossoms, is confirmed with the client before the plant is configured.
How is osmanthus 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 osmanthus extract carry?
The sources do not give one. The Sureka Life Sciences entry for Osmanthus Extract lists lutein as the offering grade but verbascoside as the active compound, which are different compounds, and Mechotech’s legacy page and the product tree state no marker. This page therefore adopts neither; the marker, if any, and whether and at what level it is carried into a hexane concrete or ethanol absolute are agreed with the buyer during process development.
Is osmanthus processed by distillation or solvent extraction?
The catalogue process for this page is solvent extraction to a concrete and absolute, following the steps in Mechotech’s legacy page: hexane extraction to a concrete, filtration and quality check, ethanol washing to an absolute, and ethanol recovery. For floral distillation routes for other flowers see Rose Essential Oil and the hub Flower & Buds Oils Distillation Plants.
Which related floral concrete and absolute plants does Mechotech list?
The product tree lists Marigold, Rose Concrete & Absolute and Tuberose next to osmanthus in the floral concrete and absolute group. Other pages include Jasmine, Magnolia and Linden Blossom, and the hub Floral Concrete & Absolute Extraction Plants.
