Hydraulic sesame oil press: 325 @ ~30 kg/batch, factory yield 55-58%, roasted or cold-pressed.
Sesame oil is defined by aroma. Whether low-temperature pressed for delicate clarity or roasted for deep amber fragrance, the entire line — from seed-lot segregation through roast curve to settled, filtered, bottled oil — must be designed around the flavor position on the shelf.
A sesame oil project should begin with two decisions that shape everything after them: which sesame lots are being used, and which aroma route the finished oil must deliver. White sesame for mild low-temperature oil, black sesame for stronger product identity, or roasted sesame for deep amber fragrance each needs a different process boundary.

Why Sesame
Sesame seed: oil 45-55%, 1000-seed 2.5-4 g, fines control <0.1%
Sesame seeds contain 45-55% oil, 18-25% protein, 5-7% moisture. The 1000-seed weight is only 2.5-4 g, so dust, stones, and foreign matter are far more disruptive than for larger seeds. Cleaning target: impurities <0.1%, stones <0.05%, by vibrating screen + air aspirator + magnetic separator. Damaged or moldy seeds raise FFA above 0.5% and shorten shelf life. White sesame yields lighter oil; black sesame contains additional pigments and antioxidants but visually darker oil. The 1000-seed weight, oil content, moisture, and impurity level should be tested per batch.
Roasted sesame oil (Asian 小磨香油 / toasted): seeds are roasted in drum or wok at 180-200°C until amber-brown (15-25 min), then pressed at 80-100°C. Yield 40-50%, strong nutty/toasted aroma, dark amber color, smoke point 177°C, used as flavor finishing oil (drizzle, marinade, dressing). Sesamol forms during roasting from sesamolin hydrolysis, boosting antioxidant capacity. Cold-pressed sesame oil (Western premium): no roasting, ≤60°C throughout, hydraulic press 355-500 ton. Yield 35-42%, light golden color, milder taste, smoke point ~177°C unrefined, used for salad, cosmetics, and infant nutrition. Refined sesame oil smoke point 232°C. Shelf life 12-24 months in dark glass 100-250 ml when FFA <0.5%, peroxide <5 meq O₂/kg, oxygen <2% headspace.
Roasted vs low-temperature
Roasted: 180-200°C roast + 80-100°C press → yield 40-50% → 小磨香油 strong-aroma oil. Cold: ≤60°C → yield 35-42% → light premium oil.
Hydraulic press class (factory sesame layout)
Hot roasted: 325 model preferred, ~30 kg sesame powder/batch with 6 partitions (factory line balances 1 roaster × 100 kg with 3 × 325 presses). Cold premium: 355-500 series (370-630 ton). Do not assume peanut 100 kg/barrel loads for sesame.
Who buys this oil
Roasted: Asian/regional 小磨香油 brands, 100-250 ml dark glass, yield 55-58%. Cold: premium salad oil, cosmetic-grade (0.22 μm sterile filter), infant food (FFA <0.3%).

How to size a sesame line
Factory sesame hot line: drum/wok roaster ~100 kg/batch → 3 × 325 hydraulic presses. Sesame is fine-seed — use ~30 kg/batch with 6 partitions (not the 100 kg peanut barrel load). Pre-press 5-10 min + main 20-30 min = 25-40 min total for 30 kg; oil yield 55-58% on good seed. Cold premium still uses 355-500 (370-630 ton) at ≤60°C. System 60 MPa, motor 2.2 kW, 380V/50Hz/3ph. Filter: pneumatic multi-layer paper + optional 1-5 μm bag. Dark glass 100-250 ml, N₂ headspace O₂ <2%.
Aroma-first process
Plan the oil first: seed variety, roast intent, aroma route — then the press
Sesame oil is one of the few edible oils where the aroma is the product. Whether mild and pale from low-temperature white sesame, or deep amber with intense toasty fragrance from roasted seeds, the flavor route must be declared before the press is discussed.

distinct aroma routes: low-temperature and roasted
Low-temperature and roasted sesame oils are different products with different sales logic. The line must be designed for one or both.
Aroma line modules
Roasting room, press cell, settling tanks, and bottle station — the modules that create sesame aroma oil
A sesame line is built around aroma: cleaning, seed-lot segregation, roast-curve control, gentle pressing, calm settling, polish filtration, and protected bottling each keep the fragrance the final product sells.
- Keep white and black sesame storage separated when the finished oil color and aroma profile are sold differently.
- Roast temperature and holding time matter more to aromatic sesame oil than tonnage claims.
- Plan calm settling before export bottles, gift packs, or shelf-ready retail cartons.
- Short transfer paths and smaller tanks help preserve aroma when the project sells premium sesame oil.
Roasting room with curve control
The roasting room is where the aroma is made. Temperature ramp speed, peak temperature, hold duration, and cooling rate together set the Maillard flavor profile; more than a preheat, it is the highest-value step on the line.
Calm settling and aroma-preserving filtration
After pressing, roasted sesame oil carries suspended particles and volatile aroma compounds. Settling must be calm and unhurried to separate sediment without losing fragrance. Filtration must balance clarity with aroma retention.
Dark-glass filling and export-ready pack-out
Sesame oil is a high-presentation product. Dark glass protects the aroma, gift cartons support the retail price, and shrink sleeves or branded labels complete the shelf impression.
Product lanes
Low-temperature premium, roasted aroma, and export gift-bottle — three sesame business models
Sesame oil projects usually fall into three different businesses, not one machine purchase. Delicate low-temperature white sesame oil, roast-forward amber aroma oil, and gift-ready bottled SKUs each demand different seed lots, different process modules, and different bottle formats.
- Low-temperature sesame materials should emphasize clean seed, controlled heat rise, and polished oil clarity.
- Roasted sesame sections should show roast-room logic, amber tone, and a stronger aroma cue.
- Export bottle sections should connect filtration, dark glass, shrink sleeves, and carton presentation.
- Black sesame deserves a separate premium route instead of being folded into mixed-seed wording.
Low-temperature premium white sesame oil
Pale, mild oil from clean white sesame. Low-temperature handling, gentle pressing, and light filtration preserve the delicate character. The bottle is typically clear or light-tinted glass with a clean, minimalist label.
Roasted aroma sesame oil
Deep amber oil with intense toasty-nutty fragrance from controlled Maillard roasting. The roast curve is the value-creation step. Settling, filtration, and dark-glass bottling preserve the aroma through to the consumer.
Export gift-bottle program
Gift cartons, multiple bottle sizes, shrink sleeves, and export-ready labeling. The line must handle short runs, seasonal peaks, and pack-out coordination. This route often combines both low-temperature and roasted SKUs in one gift set.
Buyer brief
A sesame brief should state seed variety, roast intent, aroma target, and packaging finish
Faster sesame quotes come from product language, not from saying only 'we need a press.' Seed variety, roast intent, clarity target, and bottle style all matter because they determine whether the line needs a low-temperature pressing module, a roasting room, or both.
- State whether the project uses white sesame, black sesame, or separate SKU lanes for both.
- Describe the intended oil style: cold premium, roasted aroma, or a mixed bottled-oil program.
- Say if the oil stops at crude transfer, polished filtration, dark-glass retail bottles, or gift cartons.
- Attach seed photos, current roast method, and any label or carton references the supplier should match.
- If black sesame is included, describe whether it is a separate SKU with its own aroma and presentation story.
The strongest sesame inquiries name the seed variety, the aroma route (low-temperature or roasted), the bottle format, and whether the line must handle both routes. That combination lets the factory design around flavor preservation first and tonnage second.

A sesame line should read as a 325 batch plan with a bottle at the end
Sesame copy becomes more believable when it describes small wrapped batches, a 325 hydraulic oil press, six separated layers, and a 25-40 minute pressing window. Those details keep the discussion tied to aroma, batch handling, and oil finish.
30 kg wrapped batches
Small wrapped sesame batches make cleaning, roasting curve, fill weight, cake thickness, and press timing visible in the same workflow.
Six-layer 325 pressing
The 325 machine is discussed here as a sesame batch cell: layer separation, oil flow, cake discharge, and operator access matter more than tonnage alone.
25-40 minute pressure window
The time window should be checked against roasted aroma, low-temperature oil color, cake use, and bottle clarity; no single window suits every product.

Common project questions
Align the common questions first
Should sesame always be cold pressed?
No. Roasted sesame oil (180-200°C) is the dominant Asian flavor oil — 小磨香油 / toasted sesame oil — with factory 325 yields of 55-58% on good seed. Cold-pressed (≤60°C on 355-500 class) targets Western premium salad and cosmetic markets. Choose by product, not by marketing language.
How much sesame goes in one 325 barrel?
About 30 kg sesame powder with 6 partitions; do not assume the 100 kg peanut powder load. Factory hot-line example: one ~100 kg roast batch feeds three 325 presses. Cycle: pre-press 5-10 min + main 20-30 min (25-40 min total for 30 kg).
Why does sesame oil have such long shelf life?
Sesame contains natural antioxidants sesamol and sesamin (0.4-1.0% combined). Sesamol forms during roasting from sesamolin. With FFA <0.5%, peroxide <5 meq O₂/kg, dark glass, and nitrogen headspace O₂ <2%, shelf life reaches 12-24 months at ambient temperature without refrigeration.
What should be included in a sesame oil inquiry?
Seed type (white/black), oil content, moisture, impurities. Route: roasted (180-200°C) or cold (≤60°C). Target kg/shift. Roaster capacity and number of 325 presses (or 355-500 cold). Filtration (pneumatic paper / bag / sterile). Packaging 100-250 ml dark glass with N₂? Cake plan.
What decides whether sesame oil should be roasted or low-temperature pressed?
The product lane decides it. Roasted sesame oil is built around aroma and color, while low-temperature white sesame oil needs cleaner seed, gentler pressing, and tighter filtration.
Why is destoning important before a sesame hydraulic press?
Small stones and heavy impurities can damage equipment and disturb wrapped-batch pressing. Treat cleaning and destoning as a process condition, not a minor accessory.
When does sesame oil need bottle-line planning?
If the product is sold as premium aroma oil or gift bottles, filtration clarity, bottle size, cap type, labeling, and carton rhythm should be settled beside the press cell.
