Soya
Purity Levels
20% Flavonoids (extract); protein hydrolysate and isoflavone grades also configurable
Mechotech designs and manufactures turnkey herbal extraction plants for Soya (Glycine max), covering the general soybean botanical-extraction angle — flavonoid-standardised extract, protein hydrolysate, and related soy-derived nutraceutical ingredients. We supply the complete machinery, from raw soybean preparation through extraction, purification, concentration and drying, into a consistent product for the pharmaceutical, nutraceutical, food, and functional-beverage industries.
Mechotech's Soya plant is engineered around the real processing chemistry of Glycine max: alkaline/hydro-alcoholic extraction and isoelectric precipitation recover the plant's protein and flavonoid (isoflavone) fractions, while enzymatic hydrolysis — where required — breaks the protein into bioactive, highly digestible peptides. Built in SS 316L with integrated solvent/water recovery, membrane purification, automation and full documentation, each plant is delivered as a commissioned turnkey system configured to meet the 20% Flavonoids specification (or a customer-specified protein/peptide grade), to GMP, HACCP and FSSC 22000 standards.

Manufacturing Process
Raw Material Preparation
Soybean raw material (whole bean, defatted flour, or protein isolate feedstock) is authenticated, tested for moisture, and cleaned/milled to a uniform particle size to maximise extraction efficiency.
Extraction
Milled soya is extracted with food-grade solvent (hydro-alcoholic) or alkaline aqueous conditions in closed jacketed SS 316L extractors under controlled temperature and multiple cycles to maximise recovery of flavonoids and protein.
Solid–Liquid Separation & Filtration
The extract is clarified through decanter centrifuges and a plate-and-frame filter press, followed by cartridge polish filters, to remove insoluble fibre and plant solids.
Enzymatic Hydrolysis (Optional)
For protein-hydrolysate grades, isolated soy protein is dispersed and hydrolysed with food-grade proteolytic enzymes under intelligent dosing control to produce highly digestible bioactive peptides at a target Degree of Hydrolysis.
Membrane Purification
Ultrafiltration and nanofiltration systems fractionate and purify the extract or peptide stream, removing residual carbohydrates, minerals, and enzyme residues while retaining target actives.
Concentration & Solvent/Water Recovery
The purified stream is concentrated in a falling-film/vacuum evaporator with high solvent or process-water recovery through the condenser return system.
Standardisation
The concentrate is assayed and adjusted to the declared specification — 20% Flavonoids for the extract line, or a target Degree of Hydrolysis and peptide molecular-weight profile for the hydrolysate line.
Drying & Quality Control
The standardised Soya product is spray-dried with fluid-bed cooling, then released after assay, residual-solvent, amino-acid profile, heavy-metal, microbial, and moisture testing.

Key Features
GMP Hygienic SS 316L Construction
Electropolished SS 316L product-contact surfaces use GMP hygienic design, with CIP/SIP operation between batches.
Closed-Loop Solvent & Water Recovery
Integrated recovery returns the large majority of process solvent/water per batch.
Standardised to Specification
In-process and batch-release assay are used to check the finished Soya extract against its declared specification (20% Flavonoids) or, for hydrolysate grades, a precisely controlled Degree of Hydrolysis.
Optional Enzymatic Hydrolysis Line
An integrated enzymatic hydrolysis and membrane-fractionation module lets the same plant platform produce bioactive soy peptide ingredients for sports and clinical nutrition.
Scalable Batch Capacity
Plants are configured to requirement from pilot scale upward, with modular expansion.
