芝麻油 · Sesame Oil Press line scope and commercial fit
Start here when the product direction, downstream handling, and workshop limits need to be clear before equipment is selected.
Sesame projects choose between roasted (180-200°C, yield 40-50%, strong-aroma 小磨香油) and cold-pressed (≤60°C, yield 35-42%, light premium oil), then add filtration depth and packaging to match the target market (food, infant, cosmetic).
Roasted sesame oil (小磨香油 / toasted)
180-200°C roast → 200-325 ton press at 80-100°C → yield 40-50% → 200-300 mesh filter → 100-250 ml dark glass → strong-aroma flavor finishing oil. Asian/regional retail and food service.
Cold-pressed premium sesame oil
≤60°C → 355-500 ton press → yield 35-42% → 1-5 μm bag filter → 100-250 ml dark glass → light golden, mild taste. Western premium salad and infant food markets. FFA <0.3% target for infant grade.
Cosmetic-grade sesame oil
Cold press ≤40°C → 0.22 μm sterile filter → cosmetic packaging. Compliance: GMPC / ISO 22716. Used in massage oil, skincare, hair products. Higher unit price, smaller batch.

Avoid rework
Checks that keep the line from being underspecified
- Sesame cleaning target: impurities <0.1%, stones <0.05%. Small seed size (2.5-4 g/1000 seeds) makes contamination disproportionately disruptive.
- Roast 180-200°C for 15-25 min in drum/wok. Log temperature and time per batch. Aroma consistency depends on this discipline.
- Cold-press claim requires ≤60°C end-to-end (≤40°C for cosmetic). Mixing routes on one bottle weakens the claim.
- Filtration: 200-300 mesh for crude, 1-5 μm bag for retail clarity, 0.22 μm sterile for cosmetic. Target FFA <0.5%, peroxide <5 meq O₂/kg.
- Dark glass 100-250 ml + nitrogen headspace O₂ <2% delivers 12-24 month shelf life at ambient. Sesamol/sesamin (0.4-1.0%) provide natural protection.
Line inputs
Information that changes the equipment boundary
- Seed: white or black sesame? 1000-seed weight (2.5-4 g)? Oil content (45-55%)? Moisture (5-7%)? Impurities tested?
- Route: roasted (180-200°C, yield 40-50%) or cold (≤60°C, yield 35-42%) or both?
- Capacity: kg per shift or barrels per day. Roasted cycle 40-60 min/barrel; cold cycle 60-90 min/barrel.
- Filtration: 200-300 mesh (crude), 1-5 μm bag (retail), or 0.22 μm sterile (cosmetic)?
- Packaging: 100-250 ml dark glass? Nitrogen headspace O₂ <2%? Shelf-life target 12-24 months?
- Compliance: food-grade? Infant-grade (FFA <0.3%)? Cosmetic-grade (GMPC / ISO 22716)? Halal/Kosher?
- Cake plan: defatted meal (protein 35-45%) for food, animal feed, or waste?
