Pea Meal Protein Extract

Extraction Technologies

Subcritical Water Extraction (SWE)Enzyme-Assisted Extraction (EAE)

Mechotech designs and manufactures turnkey extraction plants that process pea meal to recover pea protein. 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 2 candidate routes for pea meal and pea protein: 2 high-priority screening fits, with Enzyme-Assisted Extraction (EAE) best-ranked (rank 27 of 100).

For pea meal with pea protein as the target, there are 2 candidate technologies: Subcritical Water Extraction (SWE) and Enzyme-Assisted Extraction (EAE). By route — Subcritical Water (SWE): high-priority screening, rank 33 of 100, pressurized water; Enzyme-Assisted (EAE): high-priority screening, rank 27 of 100, water, enzyme and pH control. For the best-ranked route, Enzyme-Assisted (EAE), the screening flags: select cellulase/pectinase/protease by matrix; control enzyme cost and inactivation. 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

Pea meal is cleaned and size-reduced so pea protein can be reached by the extraction medium; particle size and moisture are set during process development.

Vessel Loading & Pressurisation

Prepared pea meal and water are loaded into a pressure-rated extraction vessel.

Subcritical Water Extraction

Water held liquid under pressure at elevated temperature extracts pea protein without an organic solvent; temperature and residence time are set to limit thermal degradation and hydrolysis.

Separation

Spent solids are separated by filtration or centrifugation and the extract is clarified before concentration.

Concentration

The clarified aqueous extract is concentrated under vacuum or by membrane systems where required; no organic solvent is used in this route.

Recovery, Standardisation & Drying

The pea protein fraction is recovered from the concentrate by a route selected during process development and checked against the target specification; drying behaviour is verified because protein-type targets can be heat-sensitive.

Key Features

Enzyme-Assisted (EAE) — High-Priority Screening Fit
Best-ranked route for pea meal: rank 27 of 100 in Mechotech's enzyme-assisted extraction screening, using water, enzyme and pH control. Ranks are directional screening priorities, not measured yield, ROI or plant guarantees.
Pea meal — 2 Candidate Routes
Routes screened for pea meal: Subcritical Water (SWE) — high-priority, rank 33; Enzyme-Assisted (EAE) — high-priority, rank 27. Each route has its own process tab above.
Meal Feed Form
The candidate routes are defined for pea meal; 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 pea protein, 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 pea meal extraction plant for pea protein?

It is a turnkey Mechotech plant that processes pea meal to recover pea protein. 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 protein extraction plants.

Which plant part or feed form does the pea meal plant process?

The candidate feedstock is pea meal. The target extract is pea protein.

Which extraction technologies are suitable for pea meal?

This feedstock has 2 candidate technologies: Subcritical Water Extraction (SWE) (high-priority screening) and Enzyme-Assisted Extraction (EAE) (high-priority screening). See the related pages on subcritical water extraction and enzyme-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: Subcritical Water Extraction (rank 33 of 100), Enzyme-Assisted Extraction (rank 27 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 pea meal?

Each technology list in Mechotech's screening ranks 100 feedstock–target opportunities (1 = highest priority). For pea meal: Subcritical Water (SWE) rank 33 (high-priority); Enzyme-Assisted (EAE) rank 27 (high-priority). The best-ranked route is Enzyme-Assisted (EAE). 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 pea meal extraction process work?

Each listed route has its own steps — Subcritical Water (SWE): Vessel Loading & Pressurisation → Subcritical Water Extraction → Separation; Enzyme-Assisted (EAE): Slurry & pH Control → Enzymatic Treatment → Enzyme Inactivation & Separation. All routes share the same outline: prepare pea meal, extract pea protein 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 pea meal extraction plant include?

The equipment follows the selected route and includes raw-material cleaning and size-reduction system; pressure-rated hot-water extraction vessel; high-pressure water pump and heat exchangers; jacketed enzyme reaction vessel with pH and temperature control; enzyme dosing and inactivation system; filtration / centrifugation system; vacuum evaporator; membrane concentration unit (where required). The full list is shown under Major Plant Equipment.

What output and specification can the pea meal plant deliver?

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

What application areas are listed for Pea Meal Protein Extract?

The application areas listed on this page are: Sports Nutrition; Protein Powders; Functional Foods; Vegan Meat Alternatives; Dairy-Free Products; Nutritional Beverages; Bakery Products; Infant Nutrition; Clinical Nutrition; Pharmaceutical Formulations.

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

Protein extraction is also covered for chickpea meal, lentil meal and mung bean meal. Mechotech also publishes a pea protein isolate case study.

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.
