Onion Seed Oil
Mechotech designs and manufactures turnkey carrier oil extraction plants for Onion Seed Oil. We supply the complete machinery to process Onion seed into a consistent, specification-grade cold-pressed carrier oil for the cosmetic and pharmaceutical industries.
Mechotech's Onion Seed Oil plant is engineered from first principles around the specific chemistry and processing requirements of Onion seed. Built in SS 316L with a mechanical expeller press, integrated filtration, and full documentation, each plant is delivered as a commissioned, performance-verified turnkey system.
Manufacturing Process
Raw Material Preparation
Onion seed is cleaned and (where required) conditioned to the optimal moisture and particle size to maximise oil yield during pressing.
Mechanical Expeller Pressing
Prepared Onion seed is fed into the screw expeller press, which mechanically compresses the material to release the fixed (carrier) oil.
Filtration
The pressed oil is clarified through a plate-and-frame filter press followed by cartridge polish filters to remove residual solids.
Collection & Quality Control
The finished Onion Seed Oil is collected and each batch verified by physical parameters (specific gravity, refractive index, acid value) before release.
Applications
- Cosmetic and personal care active ingredients
- Pharmaceutical standardised ingredient supply
- Export to regulated-market ingredient buyers
Key Features
GMP-Compliant SS 316L Construction
Electropolished SS 316L product-contact surfaces meet WHO-GMP and Schedule M requirements, with CIP operation between batches.
Mechanical Expeller Pressing
Screw expeller press recovers the fixed oil without solvent, for a cold-pressed carrier oil grade — a distinct process from Mechotech's Onion oleoresin extraction plant.
Integrated Filtration
Plate-and-frame and cartridge filtration deliver a clear, particulate-free finished oil.
Scalable Batch Capacity
Plants are configured from pilot scale to commercial capacity with modular expansion.
