Fix grit upstream
Sesame is small and dense; sand and stone survive weak cleaning. Destone and wash before roasting — no downstream filter fully fixes grit, and it wears filter media.
Sesame processing control
Sesame carries fines and, for roasted oil, char particles that cloud the bottle as it cools. The goal is a stable, clear oil — but over-filtration strips aroma compounds, so route and filtration depth must be matched.
How it works
Sesame is small and dense; sand and stone survive weak cleaning. Destone and wash before roasting — no downstream filter fully fixes grit, and it wears filter media.
Hold pressed oil warm in settling tanks so meal and gums drop out; warm oil flows and clarifies far better than oil cold off the press.
For aromatic roasted oil, a plate-frame or modest filtration keeps the flavor compounds in; polishing to a micron can flatten the very aroma you are selling.
Cold sesame has no roast aroma to protect, so chase clarity with finer filtration (micron/bag) and a chill-settling step to keep the bottle bright.
Action plan
Project scope
Sesame Oil Filtration and Clarity 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.
Two usual causes: suspended meal/char fines that were not settled or filtered out, and cool storage that drops them as haze. Warm settling plus filtration matched to the product fixes clarity; if it is gritty, the failure was cleaning, not the filter.
