Sesame routes compared: temperature, press class, yield, oil character

Hard-data comparison

Where roasted and cold routes physically diverge

Decision criteria

What actually picks roasted vs cold

• End market: Asian/regional flavor oil (drizzle, dipping) → roasted. Western premium salad / cosmetic → cold. Both SKUs → two batch programs with strict changeover.
• Filtration depth: 200-300 mesh + bag (roasted, retail) vs 1-5 μm bag (cold, premium) vs 0.22 μm sterile (cosmetic).
• Compliance: food (FFA <0.5%) vs infant (FFA <0.3%) vs cosmetic (≤40°C + GMPC / ISO 22716). Each tightens prep, press, and filter spec.
• Yield economics: 40-50% (roasted) vs 35-42% (cold). The 5-10-pt gap is recovered by 1.5-3× retail price on cold-pressed premium bottles.

Common errors

Where sesame route claims fall apart

• Marketing 'cold-pressed' on a line that exposes feed to ≥60°C anywhere in the chain (or ≥40°C for cosmetic).
• Specifying 'roasted' without naming roaster type (drum/wok), temperature (180-200°C), and time (15-25 min) — aroma consistency depends on this log.
• Using 200-300 mesh crude filter on a line marketed as premium cold-pressed for retail; 1-5 μm bag filter is required for shelf clarity.
• Mixing white and black sesame on one line without changeover and tank flushing — destroys SKU integrity and antioxidant claims.

Project boundary

What to confirm before scoping Sesame Cold vs Roasted | 180-200°C / ≤60°C, Yield 40-50% / 35-42%, Smoke Point 177°C

Sesame Cold vs Roasted | 180-200°C / ≤60°C, Yield 40-50% / 35-42%, Smoke Point 177°C should not be quoted from an equipment name alone. Check feed lots, target oil, post-press handling, and packing rhythm in one scope before deciding which Sesame Oil Press modules stay. Factory sesame hot: ~30 kg/batch with 6 partitions on 325; cold uses 355–500. Do not use peanut 100 kg barrel loads.

When feed condition, moisture, impurities, batch weight, and product position are unclear, press tonnage and filter area become guesswork. Factory systems share 60 MPa and 2.2 kW motors; hot pure press is 30–40 min/barrel and cold pure press is ~2 h/barrel — cycle time matters more than brochure tonnage.

• Confirm whether feed is whole seed, kernels, pretreated material, or an existing semi-finished stream.
• Confirm whether the target is crude oil, filtered oil, bottled oil, drum ingredient oil, or a refining handoff.
• Hot cycle reference: pure press 30-40 min/barrel, ~1.5 h for 2 barrels with loading; cold pure press ~2 h/barrel, ~4.5 h for 2 barrels.
• Confirm batch rhythm, labor, changeover, retained samples, power (often 380V/50Hz/3ph), and site install conditions.

Factory model check

Match hot / cold models to factory hard data

When discussing Sesame Cold vs Roasted | 180-200°C / ≤60°C, Yield 40-50% / 35-42%, Smoke Point 177°C, pin models to published factory specs — not tonnage alone.

Hot 300/325: 300–325 ton, 60 MPa system, standard barrel Ø390×800 mm / max 100 kg, pure press 30–40 min/barrel, ~1.5 h for 2 barrels with loading, 2.2 kW motor. Cold 355/400/426/480/500: 370–630 ton, integrated frame, same 100 kg standard barrel, pure press ~2 h/barrel, ~4.5 h for 2 barrels with loading; optional Ø300 high-pressure barrel max 60 kg. Residual oil target ~≤5% (peanut hot often 6–8% measured).

• Standard barrel Ø390×800 mm, max ~100 kg crushed feed; optional Ø300 high-pressure barrel max ~60 kg.
• Cylinder material 27SiMn; cold frames are integrated molded steel; hot frames are typically H-type channel steel.
• Factory sesame hot: ~30 kg/batch with 6 partitions on 325; cold uses 355–500. Do not use peanut 100 kg barrel loads.

Equipment check

project scope needs to land in equipment interfaces

After Sesame Cold vs Roasted | 180-200°C / ≤60°C, Yield 40-50% / 35-42%, Smoke Point 177°C is clear, write the interfaces: how preparation feeds the press, how oil leaves the press, how filtration connects to tanks, and how packing receives finished oil.
