Counter-Current Extraction (CCE)Ultrasound-Assisted Extraction (UAE)Hybrid ExtractionMicrowave-Assisted Extraction (MAE)

Mechotech designs and manufactures turnkey extraction plants that process lemongrass leaves to recover phenolic acids. We supply the machinery for the route selected after screening — raw-material preparation, extraction, separation, concentration or recovery, and drying or collection — configured to the target specification. Mechotech's technology screening identifies 4 candidate routes for lemongrass leaves and phenolic acids: 4 relevant screening fits, with Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE) and Microwave-Assisted Extraction (MAE) jointly best-ranked (rank 41 of 100).

For lemongrass leaves with phenolic acids as the target, there are 4 candidate technologies: Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). By route — Counter-Current (CCE): relevant screening, rank 41 of 100, ethanol/water or suitable food-grade solvent; Ultrasound (UAE): relevant screening, rank 41 of 100, ethanol/water or water; Hybrid: relevant screening, rank 43 of 100, sequence selected by target; Microwave (MAE): relevant screening, rank 41 of 100, ethanol/water or water. For the first-listed of the best-ranked routes, Counter-Current (CCE), the screening flags: counter-current contact and solvent recovery; verify bed flow and fines management. These are screening candidates rather than guarantees: the final technology, operating parameters and plant configuration are established during process development and pilot validation. Product-contact parts are built in SS 316L with CIP-cleanable design, and automation is configured to the project.

Manufacturing Process

Each extraction method follows a different process — pick a method to see its steps.

Raw-Material Preparation

Lemongrass leaves are cleaned and size-reduced so phenolic acids can be reached by the extraction medium; particle size and moisture are set during process development.

Counter-Current Loading

Prepared lemongrass leaves are fed into a multi-stage solid–liquid counter-current extractor where fresh ethanol/water or a suitable food-grade solvent meets the most-depleted material.

Counter-Current Extraction

Solvent flows against the solids across stages to draw out phenolic acids; bed flow and fines management are verified during pilot work.

Extract (Miscella) Collection

The phenolic acids-bearing miscella is collected from the fresh-feed end while spent solids are discharged from the solvent-entry end.

Concentration & Solvent Recovery

Solvent is removed from the clarified phenolic acids-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.

Standardisation & Drying

The phenolic acids extract is assayed against the declared target specification and dried or supplied as a concentrate, according to the requirement.

Key Features

Joint Best-Ranked Routes — Relevant Screening Fit
Joint best-ranked routes for lemongrass leaves: Counter-Current (CCE), Ultrasound (UAE) and Microwave (MAE), all at rank 41 of 100 in their respective screenings. Ranks are directional screening priorities, not measured yield, ROI or plant guarantees.
Lemongrass leaves — 4 Candidate Routes
Routes screened for lemongrass leaves: Counter-Current (CCE) — relevant, rank 41; Ultrasound (UAE) — relevant, rank 41; Hybrid — relevant, rank 43; Microwave (MAE) — relevant, rank 41. Each route has its own process tab above.
Leaves Feed Form
The candidate routes are defined for lemongrass leaves; feedstock assay and moisture are measured as pilot inputs and the feed form is set during process development.
Parameters Fixed After Pilot Trials
Recovery of phenolic acids, selectivity, solvent or water duty, quality and cleaning are measured in pilot trials, starting with small-scale feed trials, before final plant parameters are fixed.
SS 316L Hygienic Construction
Product-contact surfaces are SS 316L and CIP-cleanable, in a hygienic design suited to food, nutraceutical and pharmaceutical supply chains; PLC-SCADA automation with recipe control can be configured to the project scope.

Frequently Asked Questions

What is a lemongrass leaf extraction plant for phenolic acids?

It is a turnkey Mechotech plant that processes lemongrass leaves to recover phenolic acids. The plant covers raw-material preparation, extraction, separation, concentration or fraction collection, and drying or packing, and is configured to the target specification. It sits within Mechotech's wider range of herbal extraction plants.

Which plant part or feed form does the lemongrass leaf plant process?

The candidate feedstock is lemongrass leaves. The target extract is phenolic acids.

Which extraction technologies are suitable for lemongrass leaves?

This feedstock has 4 candidate technologies: Counter-Current Extraction (CCE) (relevant screening), Ultrasound-Assisted Extraction (UAE) (relevant screening), Hybrid Extraction (relevant screening) and Microwave-Assisted Extraction (MAE) (relevant screening). See the related pages on counter-current extraction, ultrasound-assisted extraction, hybrid extraction and microwave-assisted extraction. These are screening candidates, not guarantees of yield, purity or recovery; the route is confirmed through process development and pilot validation. In Mechotech's technology screening these candidates are ranked directionally — relevant: Counter-Current Extraction (rank 41 of 100), Ultrasound-Assisted Extraction (rank 41 of 100), Hybrid Extraction (rank 43 of 100), Microwave-Assisted Extraction (rank 41 of 100). Ranks are directional screening priorities at method-family level, not measured yield, ROI or plant guarantees.

How does Mechotech's screening rank the candidate routes for lemongrass leaves?

Each technology list in Mechotech's screening ranks 100 feedstock–target opportunities (1 = highest priority). For lemongrass leaves: Counter-Current (CCE) rank 41 (relevant); Ultrasound (UAE) rank 41 (relevant); Hybrid rank 43 (relevant); Microwave (MAE) rank 41 (relevant). The best-ranked routes are Counter-Current (CCE), Ultrasound (UAE) and Microwave (MAE). Ranks are directional screening priorities, not measured yield, ROI or plant guarantees, and the evidence is at method-family level, so every route needs pilot validation.

How does the lemongrass leaf extraction process work?

Each listed route has its own steps — Counter-Current (CCE): Counter-Current Loading → Counter-Current Extraction → Extract (Miscella) Collection; Ultrasound (UAE): Slurrying → Ultrasonic Cavitation → Separation; Hybrid: Stage Sequence Selection → First Assisted Stage → Second / Combined Stage; Microwave (MAE): Medium Mixing → Microwave Heating & Extraction → Separation. All routes share the same outline: prepare lemongrass leaves, extract phenolic acids using the technology-specific step, separate and clarify the extract, concentrate it, and recover, standardise and dry. The process tabs above show every step.

What equipment does the lemongrass leaf extraction plant include?

The equipment follows the selected route and includes raw-material cleaning and size-reduction system; multi-stage counter-current extractor; solvent storage tanks and transfer pumps; ultrasonic extraction vessel with transducer system; combined extraction train (stage equipment per the sequence selected during process development); microwave extraction vessel with temperature and safety controls; filtration / centrifugation system; vacuum evaporator. The full list is shown under Major Plant Equipment.

What output and specification can the lemongrass leaf plant deliver?

The listed output is phenolic acids extract. The plant is configured to a customer-declared specification for phenolic acids. No fixed purity, grade or yield is claimed until pilot results are available.

What application areas are listed for Lemongrass Leaf Phenolic Acids Extract?
