Quality control
Most sesame-oil complaints trace to feed stock, moisture, roast or cook, and filtration — not to pressing tonnage. Work the list below top to bottom before you change anything on the machine.
Common defects
Over-roasting past roughly 200°C or burnt fines drag bitterness into the oil, ruining a premium batch. Fix: Tighten the roast curve and reject scorched lots; for aromatic roasted oil keep heat even and time bounded rather than chasing color.
Sesame is a small, dense seed; sand and stones survive inadequate cleaning. Fix: Add destoning and washing before roasting — grit is a pretreatment failure, not a press problem.
Fine meal particles stay suspended and cloud the oil as it cools. Fix: Warm settling plus polish filtration keeps clarity; avoid filling cold oil straight off the press.
Sesame aroma compounds oxidize under heat, light, and air. Fix: Dark glass, optional N₂ headspace, cool storage, and small bottles so aroma is consumed before it fades.
Fix it in one scope
Before adjusting the press, confirm feed grade, moisture, the roast/cook window, and filtration depth for Sesame oil. Those four cover most of this list; the press mostly reveals what came before it.

Sesame Oil Problems and Fixes 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 net pressing is 30–40 min/barrel and cold net pressing is ~2 h/barrel — cycle time matters more than brochure tonnage.
Factory model check
Pin models to published factory specs before tonnage talk.
Hot 300/325: 300–325 ton, 60 MPa system, standard barrel Ø390×800 mm / max 100 kg, net pressing 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, net pressing ~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).
Equipment check
Once the route 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.
Record feed form, daily volume, moisture, and sorting needs so pretreatment is not left to operators.
Factory hot sesame lines often use pneumatic multi-layer paper filters; cold adds polish filtration and N₂. Match bottling to the ~25–40 min cycle at ~30 kg/batch.
Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.
Usually no. Most sesame-oil defects start with feed stock, moisture, roast/cook, or filtration. The press controls pressure and cycle, not the chemistry already in the seed.
