Introduction
Vegetable oils are a staple food in households around the world and a key ingredient for the food industry. As demand continues to grow, investing in an efficient vegetable oil production line is essential for vegetable oil producers.
Chemsta’s turnkey solutions are based on more than 30 years of engineering experience, providing custom designs, energy-efficient systems and ISO-compliant production lines to customers around the world.
This guide will walk you through the entire process – raw material pre-treatment, extraction technology, refining stages, automation and procurement – so you can make an informed decision and optimize your return on investment.
What is a Vegetable Oil Production Line?
An industrial system that transforms oil‑rich seeds (like soybean, rapeseed, sunflower, peanut, cottonseed, corn germ) into edible oil via pretreatment, extraction, refining, and packaging. It’s widely used across food processing and agricultural enterprises.
Core Process Flow
- Raw Material Pretreatment: cleaning, dehulling, flaking or crushing
- Primary Oil Extraction: screw/hydraulic pressing or solvent extraction
- Desolventizing & Meal Handling (if solvent method)
- Crude Oil Recovery
- Refining: degumming, neutralizing, bleaching, deodorizing, winterization
- Storage & Packaging/refill systems
Extraction Methods
Mechanical Pressing
- Screw or hydraulic presses are suitable for medium to small‑scale setups.
- Cold pressing (<50 °C) preserves oil flavor and nutritional quality but yields are lower (35–50%) than solvent methods.
Solvent Extraction
- Used at industrial scale to recover up to 95–98% of residual oil via loop extractors or rotary extractors with miscella recycling.
Refining Process
Refining transforms crude oil into food‑safe, high‑quality edible oil:
- Degumming – remove phospholipids with water or acid
- Neutralization – alkali treatment to reduce free fatty acids
- Bleaching – remove pigments and metals using activated earth and vacuum filtration
- Deodorization – steam under vacuum to eliminate odor and volatile impurities
- Winterization (optional) – for oils like sunflower or corn to remove waxes
Key Equipment
Chemsta provides a full set of equipment, including:
- Cleaning, dehuller, magnetic separator, flaker for pretreatment
- Screw / hydraulic oil press, or solvent extraction systems like loop or rotary extractors
- Desolventizer‑toaster, meal conveyors, and dryers for solvent lines
- Refining units: degumming reactors, neutralizers, bleaching towers, vacuum bleachers, filters, deodorizing tower, heat exchangers, centrifuges, vacuum pumps
Automation & Control
Fully integrated control systems monitor flow rates, temperatures, solvent concentration, equipment status, energy usage, yield tracking, and alarms. Automation boosts consistency, reduces labor, and improves traceability—essential for export or corporate-grade clients.

FAQ
What oilseed types are supported?
Soybean, rapeseed, sunflower, peanut, cottonseed, corn germ, sesame, rice bran, etc.
What are typical yields?
Mechanical pressing yields ~35‑50%; solvent systems can reach 95–98% total yield.
How long to install a full line?
Typically 3–5 months for manufacturing, delivery, installation, and commissioning.
Is solvent extraction safe?
Yes—systems are sealed, explosion‑proof, and include solvent recovery and VOC controls.
