Soy Meal Protein Extract

Soy Meal Protein Extract
Extraction Technologies
Mechotech designs and manufactures turnkey extraction plants that process soy meal to recover soy 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. Candidate extraction technologies for soy protein: Subcritical Water Extraction (SWE) and Enzyme-Assisted Extraction (EAE) (2 in total).
For soy meal with soy protein as the target, there are 2 candidate technologies: Subcritical Water Extraction (SWE) and Enzyme-Assisted Extraction (EAE). Polar, water-soluble-type targets point to water-based routes, with thermal-degradation, hydrolysis and drying behaviour checked during pilot work. 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
Soy meal is cleaned and size-reduced so soy protein can be reached by the extraction medium; particle size and moisture are set during process development.
Vessel Loading & Pressurisation
Prepared soy meal and water are loaded into a pressure-rated extraction vessel.
Subcritical Water Extraction
Water held liquid under pressure at elevated temperature extracts soy 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 soy 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.
Raw-Material Preparation
Soy meal is cleaned and size-reduced so soy protein can be reached by the extraction medium; particle size and moisture are set during process development.
Slurry & pH Control
Prepared soy meal is slurried in water with pH and temperature set for the enzyme system.
Enzymatic Treatment
An enzyme (for example a cellulase, pectinase or protease, selected for the soy meal matrix) breaks down bound cell-wall material to release soy protein; enzyme cost and specificity are validated at pilot scale.
Enzyme Inactivation & Separation
The enzyme is inactivated and spent solids are separated by filtration or centrifugation.
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 soy 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
Technology-Matched Process Design
The plant is configured around the 2 candidate technologies for this feedstock: Subcritical Water (SWE) and Enzyme-Assisted (EAE).
Target-Specific Configuration
Equipment and process steps are selected around the soy protein target and the soy meal feed form, and are finalised after pilot work.
Parameters Fixed After Pilot Trials
Recovery, selectivity, solvent or water duty, quality and cleaning are measured in pilot 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.
Configurable Automation
PLC-SCADA automation with recipe control can be configured to the project scope.
