Nutraceutical & Botanical Extraction Plants

This plant is for a processor who sells a plant extract against a number, such as a declared level of a marker compound, rather than as a general herbal product. The decisions that shape the plant are therefore specific: which botanical and plant part, which compound is being measured and at what level, which method the laboratory will use to check it, how much residual solvent the customer will tolerate, and what paperwork the supplement or pharmaceutical buyer expects to see. The plant is listed as a full train in SS 316L, with the planning capacity range shown elsewhere on this page.

The machinery matches the herbal extraction train: preparation, extraction, filtration, concentration with solvent recovery and drying. The difference lies in the last third of the line, where purification and standardisation are given more weight. Samples are assayed against the marker-compound target and the batch is adjusted before it is dried. Wetted parts are SS 316L and controls are PLC-based. Supplement and pharmaceutical customers audit their suppliers, so hygienic design, material records for product-contact parts and batch records are part of the design brief from the start.

Indicative Capacity Range

  • 100–3,000 kg dry feed/day

Key Specification Inputs

Typical Process Route

1

Identity and moisture check

The botanical, plant part and moisture of each lot are confirmed before use. Lot-to-lot variation in a natural material is normal, so records of origin and harvest are worth keeping from the start.

2

Milling

Material is ground to an even particle size so the solvent contacts it uniformly and later filtration stays workable.

3

Extraction

Water or alcohol (food or pharma grade) is used in closed, jacketed SS 316L extractors. Temperature is controlled, and repeated cycles are run to take out the target compounds as completely as the specification needs.

4

Clarification

The extract (miscella) passes through a plate-and-frame filter press, then cartridge filters, to remove fine solids before concentration.

5

Concentration with solvent recovery

A falling-film or vacuum concentrator removes solvent at reduced temperature. Condensed solvent is returned for reuse through the condenser system.

6

Purification, isolation and standardisation

Where the specification demands it, the concentrate is purified and the target compounds are isolated. It is then assayed against the marker-compound target and adjusted.

7

Drying and release testing

The standardised extract is spray dried or vacuum dried. Some concentrates are dried with a carrier or diluent that improves flowability and mixability, and the specification should state it. Release tests follow the agreed specification and typically cover assay, residual solvent, heavy metals, microbial load and moisture.

Plant Output

Plant extract standardised to a declared marker-compound levelFree-flowing, low-moisture powder where a dryer is includedPurified or isolated compound fraction where purification is includedRecovered solvent returned to the process

Applications

  • Dietary supplement and nutraceutical formulators
  • Suppliers of standardised botanical ingredients
  • Ingredient manufacturers working alongside the pharmaceutical sector
  • Functional food and beverage makers
  • Sales to buyers in regulated export markets

Key Features

  • Hygienic stainless-steel build

    Electropolished SS 316L wetted surfaces and clean-in-place washing between batches.

  • Built around a declared target

    In-process and batch-release assays check each extract against its marker-compound specification.

Frequently Asked Questions

What should be decided before sizing a nutraceutical extraction plant?
Five things: the botanical and plant part, the marker compound and the level you will declare, the analytical method that will be used to verify it, the solvent route and the residual-solvent limit your customers set, and the capacity per day. Registry planning figures are given in terms of dry feed per day, so state moisture clearly when you quote your own volumes. The more precisely these are written, the less the proposal has to assume.
What does 'standardised' mean for a botanical extract?
It means the extract is made and tested so that a chosen marker compound sits within a declared range, batch after batch. Marker compounds are often used as in-process controls, but they may or may not be linked to therapeutic activity, and their levels do not always move in step with other constituents. Standardisation is also wider than one number: it is the whole body of information and controls that optimises batch-to-batch consistency, including raw-material and process controls. It does not mean the extract is pure. The marker, the range and the assay method should all be written into the specification, because the same words can be used loosely. The plant includes assay stages in the process to check this.
How does this differ from a herbal extraction plant?
The machinery is closely related. The herbal extraction plant covers the broad run of medicinal and traditional herbs, while this one is set up for extracts that must hit a declared marker value for supplement or nutraceutical use. If you intend to run several botanicals through the same line, the multi-herbal extraction plant is suited to that kind of multi-product use.
When is a dedicated curcumin plant the better choice?
Where turmeric and its curcuminoids are the only product. A curcumin plant is designed to purify and standardise that one fraction, while this plant covers standardised extracts from many source plants. See the curcumin extraction plant page if turmeric is your target.
How do I choose the solvent and handle residual-solvent limits?
Water is simplest to handle but may not recover less polar compounds. Ethanol, alone or mixed with water, can take up both polar and non-polar substances, but it is flammable, so the extraction and recovery areas need explosion-protected electrics, good ventilation and closed solvent transfer. Residual solvent in the finished extract must stay within the limit set by your customer; pharmaceutical buyers usually apply recognised limits by solvent class. Drying and the concentration step both influence the residue, so the limit should be given to the supplier early.
What documentation will a supplement or pharmaceutical customer ask for?
Buyers of standardised extracts usually ask for a certificate of analysis for every lot, batch records, and identity and origin records for each raw-material lot, so these are kept from intake onwards. On the plant side, expect drawings, material records for product-contact parts, a process description and the cleaning method for the vessels. The nutraceutical and pharmaceutical solutions page shows how related scope is organised.
Do I need the purification and isolation stage?
Only if the declared marker level calls for it. A moderate level can often be reached by extraction, concentration and adjustment with a carrier or diluent. A high level means purifying the concentrate, for example by resin-column or crystallisation steps, which adds equipment, solvent handling and cost. Settle the declared level and the assay method first, because that choice changes the plant more than any other.
What does a nutraceutical extraction plant cost?
Price depends on the botanical, the declared marker level and whether purification is needed, the capacity, and the choice of filtration, concentration and drying equipment. Send your botanical, capacity and specification and a project-specific quotation will be prepared.
