With sesame, dust you don't remove becomes a black speck you can't filter out

Feed entry

Three feed conditions, three different scopes

Where your seed enters the line decides how much equipment the quote must carry. Raw mixed seed needs the full cleaning train; cleaned-but-unsorted seed needs lot separation; clean sorted lots let the conversation jump straight to route and press class. Find your starting point below.

Control points

The preparation numbers that protect aroma and clarity

Prep flow

Preparation steps before the first barrel

• Clean with a vibrating screen, air aspirator, magnetic separator, and destoner to impurities <0.1% and stones <0.05%; protect both filtration and oil clarity.
• Separate white and black lots and flush tanks between them; mixing destroys retail SKU color and label integrity.
• Verify oil content (45-55%) and moisture (5-7%) per batch, and reject damaged or moldy seed that pushes FFA above 0.5%.
• Set the route before pressing: roast 180-200°C for 15-25 min (aroma oil) or stay ≤60°C end-to-end (cold premium); log the roast per batch.

Strong front-end preparation removes most arguments about machine size that are really cleaning, variety, and roast-discipline problems.

Why it matters

Why preparation, not tonnage, decides sesame quality

When a sesame line underperforms, the press is usually the first thing blamed and the last thing at fault. A hydraulic press applies steady pressure; it cannot remove the dust, stones, and metal that a fine seed carries, nor can it repair an aroma that was over- or under-roasted upstream. Start with cleaning, because sesame is small: at a 1000-seed weight of only 2.5-4 g, the same gram of grit that a sunflower or peanut line would shrug off becomes a visible dark speck in a 100 ml bottle and a fines load that blinds the filter. A vibrating screen, air aspirator, magnetic separator, and destoner bringing impurities below 0.1% and stones below 0.05% is therefore not a luxury but the entry condition for retail-grade oil. Next is variety and lot discipline. White sesame yields a lighter oil; black sesame carries more pigment and yields a darker oil with slightly higher antioxidant content, so mixing the two without separated lots and tank flushing quietly destroys the SKU identity that retail and certified-organic buyers pay for. Then comes the roast decision, which is really the product decision: 180-200°C for 15-25 minutes builds the nutty aroma and the sesamol that forms from sesamolin, while a cold route holds everything at or below 60°C to keep the oil light and mild. Because oil content (45-55%) and moisture (5-7%) vary between incoming lots, testing every batch and rejecting damaged or moldy seed — which pushes free fatty acids above 0.5% and shortens the 12-24 month shelf life — is what keeps quality consistent shift after shift. Get these things right and the hydraulic press becomes predictable; skip them, and no amount of extra tonnage will put the aroma, color, or clarity back.

Project boundary

What to confirm before scoping Sesame Raw Material Preparation: Fine-Seed Cleaning, Variety Separation, and the Roast Decision

Sesame Raw Material Preparation: Fine-Seed Cleaning, Variety Separation, and the Roast Decision 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 Raw Material Preparation: Fine-Seed Cleaning, Variety Separation, and the Roast Decision, 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 Raw Material Preparation: Fine-Seed Cleaning, Variety Separation, and the Roast Decision 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.
