Mechotech designs and manufactures turnkey extraction plants that process grape pomace to recover resveratrol and polyphenols and anthocyanins. 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 assigns routes by target — resveratrol and polyphenols: Counter-Current (CCE), Ultrasound (UAE), Hybrid and Microwave (MAE); anthocyanins: Subcritical Water (SWE), Enzyme-Assisted (EAE) and Hybrid; the best-ranked route overall is Subcritical Water Extraction (SWE) (high-priority screening, rank 6 of 100).

For grape pomace with resveratrol and polyphenols and anthocyanins as the target, there are 6 candidate technologies: Counter-Current Extraction (CCE), Subcritical Water Extraction (SWE), Ultrasound-Assisted Extraction (UAE), Enzyme-Assisted Extraction (EAE), Hybrid Extraction and Microwave-Assisted Extraction (MAE). By route — Counter-Current (CCE) for resveratrol and polyphenols: high-priority screening, rank 7 of 100, ethanol/water or suitable food-grade solvent; Subcritical Water (SWE) for anthocyanins: high-priority screening, rank 6 of 100, pressurized water; Ultrasound (UAE) for resveratrol and polyphenols: high-priority screening, rank 7 of 100, ethanol/water or water; Enzyme-Assisted (EAE) for anthocyanins: exploratory screening, rank 78 of 100, water, enzyme and pH control; Hybrid for resveratrol and polyphenols: high-priority screening, rank 7 of 100, sequence selected by target; Hybrid for anthocyanins: relevant screening, rank 66 of 100, sequence selected by target; Microwave (MAE) for resveratrol and polyphenols: high-priority screening, rank 7 of 100, ethanol/water or water. For the best-ranked route, Subcritical Water (SWE), the screening flags: pressure-rated hot water; check thermal degradation, hydrolysis and downstream drying. 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

Grape pomace is cleaned and size-reduced so resveratrol and polyphenols can be reached by the extraction medium; particle size and moisture are set during process development.

Counter-Current Loading

Prepared grape pomace is 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 resveratrol and polyphenols; bed flow and fines management are verified during pilot work.

Extract (Miscella) Collection

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

Standardisation & Drying

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