Stainless Steel CO2 Extraction Equipment for Essential Oils

In the world of essential oil production, purity and precision are non-negotiable. Whether extracting lavender, rose, frankincense, or citrus oils, the equipment used plays a defining role in retaining aroma, flavor, and bioactivity. Among all modern techniques, supercritical CO2 extraction using stainless steel equipment offers unmatched hygiene, durability, and safety.

This article explores how the co2 supercritical extraction machine from Shanghai North Brooks Co.,ltd., built entirely from food-grade stainless steel, delivers high-quality essential oil extraction for commercial and craft producers alike.

1. Why Stainless Steel Matters in CO2 Extraction

Stainless steel, especially SUS304 and SUS316, is preferred for CO2 extraction systems because:

• It’s non-reactive with botanical compounds

• Easy to clean and sanitize

• Withstands high pressure and temperature

• Complies with food, pharma, and cosmetic regulations

Inferior materials like aluminum or low-grade alloys can contaminate essential oils, corrode over time, or fail under pressure — putting operators and product integrity at risk.

2. North Brooks CO2 Extraction System – Fully Stainless Steel Design

Shanghai North Brooks Co.,ltd. fabricates their entire CO2 system — from extraction vessels to tubing and valves — in pharmaceutical-grade SUS316 stainless steel.

The entire system is corrosion-resistant, suitable for citrus oils (acidic), and easy to CIP (Clean-in-Place).

3. Target Applications: Essential Oil Extraction

North Brooks systems are widely used for:

• Lavender, rose, jasmine, rosemary

• Frankincense, myrrh, cinnamon bark

• Citrus peels (orange, lemon, bergamot)

• Seed oils (carrot seed, fennel, anise)

All without the use of alcohol or solvents — ideal for clean-label, organic-certified essential oils.
