Pick the press frame for the route — the hydraulics are the same across the range

Supporting modules

The modules that turn a press into a peanut line

• Shelling and cleaning: removes shell (30-40% of pod), stones, and damaged kernels before the press — sized to match press throughput.
• Roasting: flat-bottom woks or drum roasters at 160-180°C for the hot route; the roaster, not the press, often sets hourly rhythm.
• Filtration and settling: 200-300 mesh plate-frame filter plus settling tanks keep crude oil clear and sediment ≤0.1%.
• Storage and cake: crude-oil tanks plus a cake route (protein 45-50%) for feed, food-grade flour, or re-pressing.

A line runs at the speed of its slowest stage. Matching shelling, roasting, filtration, and cake handling to the press is what actually protects throughput and yield.

What to confirm before scoping Peanut Hydraulic Oil Press Line

Peanut Hydraulic Oil Press Line 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.
