Mechotech designs and manufactures turnkey herbal extraction plants that process spinach leaves to recover polyphenols, with a 30% Nitrate content specification listed for this product. We supply the machinery for the route selected after screening — raw-material preparation, extraction, separation, concentration or recovery, and drying or collection. Candidate extraction technologies for polyphenols: Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE) (4 in total).

For spinach leaves with polyphenols as the target, there are 4 candidate technologies: Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). Ethanol/water- or water-based media suit this type of target, with solvent recovery where a solvent is used. 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

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

Counter-Current Loading

Prepared spinach 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 polyphenols; bed flow and fines management are verified during pilot work.

Extract (Miscella) Collection

The polyphenols-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 polyphenols-bearing extract under vacuum and returned through a solvent-recovery loop; recovery performance is confirmed at pilot scale.

Standardisation & Drying

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

Configurable Automation
PLC-SCADA automation with recipe control can be configured to the project scope.

Frequently Asked Questions

What is a spinach leaf extraction plant for polyphenols?

It is a turnkey Mechotech plant that processes spinach leaves to recover polyphenols. 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 spinach leaf plant process?

The candidate feedstock is spinach leaves. The target extract is polyphenols.

Does Mechotech supply the complete machinery for Spinach Leaf Extract?

Yes. Mechotech supplies the complete turnkey plant for Spinach Leaf Extract — engineered, fabricated at our Hyderabad facility, installed and commissioned as a single integrated system.

What specification can the Spinach Leaf Extract plant achieve?

The catalogue lists 30% Nitrate content for this extract. The plant is configured to the client’s target specification; the specification achieved is established during process development and pilot validation, and batch-release testing with certificate-of-analysis documentation is defined with the client.

Which industries use the Spinach Leaf Extract plant?

Pharmaceutical, nutraceutical, food and flavour, cosmetic, and fragrance manufacturers use Mechotech plants for consistent, compliant production.

Why do the candidate technologies target polyphenols when the specification on this page is 30% nitrate content?

In Mechotech's technology screening the candidate routes are assessed against different targets: the counter-current, ultrasound, hybrid and microwave routes with polyphenols as the target. The 30% nitrate content specification on this page is the catalogue specification for this product; which target and grade apply is confirmed during process development and pilot validation.

Which extraction technologies are suitable for spinach leaves?

This feedstock has 4 candidate technologies: Counter-Current Extraction (CCE), Ultrasound-Assisted Extraction (UAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). 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 — high-priority: Counter-Current Extraction (rank 29 of 100), Ultrasound-Assisted Extraction (rank 29 of 100), Hybrid Extraction (rank 30 of 100), Microwave-Assisted Extraction (rank 29 of 100). Ranks are directional screening priorities at method-family level, not measured yield, ROI or plant guarantees.

How does the spinach leaf extraction process work?

Each route follows the same outline: prepare spinach leaves, extract polyphenols using the technology-specific step, separate and clarify the extract, concentrate it, and recover, standardise and dry. The process tabs above show the steps for each listed technology.

What equipment does the spinach 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 selected sequence); microwave extraction vessel with temperature and safety controls; filtration / centrifugation system; vacuum evaporator. The full list is shown under Major Plant Equipment.

Which related Mechotech extraction pages cover the same material or target?

Spinach leaf colour is covered on the Leaves - Spinach / Chamomile / Nettle page and African spinach on the African Spinach Leaf Extract page. Leaf polyphenol extraction is also covered for nettle leaves.

What capacity is available and is a pilot trial recommended?

Capacity is configured to requirement. Mechotech's technology screening recommends starting with small-scale feed trials to measure recovery, selectivity, solvent or water duty, quality and cleaning before pilot and commercial plant sizes are fixed.
