Peanut oil press FAQ: route, yield, aflatoxin, and quote data

Core decisions

Three decisions that drive every peanut quote

Hard data

Numbers a peanut inquiry should already know

• Oil yield: 40-48% hot, 35-42% cold (kernel oil content 44-56%). Residual cake oil 6-8% hot, 8-10% cold.
• Cake protein: 45-50%. Defatted meal sells as feed (poultry/aquaculture) or food-grade peanut flour.
• Aflatoxin B1 limit: <20 μg/kg (EU 1881/2006), <20 ppb (US FDA). Pre-press kernel inspection + UV sorting + lab test per batch.
• Standard barrel: 390 × 800 mm, ~100 kg kernel load. Model 325 uses 14 partitions to hold pressure across each cake during the 30-45 min cycle.
• Smoke point: 230°C refined peanut oil (high-heat frying), 160°C unrefined cold-pressed (salad/finishing).

Quote inputs

Send these to skip the first three rounds of clarification

• Feed: pods or kernels, kernel grade, moisture %, aflatoxin test result if available.
• Route: hot (160-180°C roast) or cold (≤60°C), with target yield and final smoke-point grade.
• Capacity: kg/shift or barrels/day. One model 325 = ~2 barrels per 1.5 h including load/unload.
• Existing equipment: roaster (wok / drum), settling tank, plate-frame filter — keep, replace, or extend?
• Cake plan: feed grade, food-grade flour (defatting + grinding), or local resale.

What to confirm before scoping Peanut Oil Press FAQ | Hot 160-180°C / Cold ≤60°C, Yield 40-48%, Aflatoxin <20 μg/kg

Peanut Oil Press FAQ | Hot 160-180°C / Cold ≤60°C, Yield 40-48%, Aflatoxin <20 μg/kg 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 Peanut Oil Press modules stay. Listed on the factory hot-press page — discuss 300/325 first.

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

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, 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.
• Listed on the factory hot-press page — discuss 300/325 first.

Equipment check

project scope needs to land in equipment interfaces

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.
