Every peanut press from model 300 to 500 shares one 60 MPa system and a 2.2 kW motor. What changes is frame strength and pressure stability. So the model follows the route and barrel rhythm, and the line is built of matching modules around it.
How a peanut hydraulic oil press fits a working line: model ladder 300/325 hot vs 355-500 cold, same 60 MPa / 2.2 kW hydraulics, plus shelling, roasting, filtration, storage, and cake modules.
Roast 160-180°C → moisture to 3-5% → 300-325 ton hydraulic press at 80-100°C → 100 kg/barrel, 30-40 min → plate-frame filter 200-300 mesh → crude oil clarity target: sediment ≤0.1%, moisture ≤0.2%.
Hot peanut lines: 300-325 ton, 80-100°C, higher throughput. Cold premium: 355-500 ton, ≤60°C, lower yield but premium positioning. Do not use cold-press claims for hot-route oil.
Standard barrel 390 mm × 800 mm loads ~100 kg. Model 325 uses 14 partitions. Hot cycle: 30-40 min/barrel. Cold cycle: 60-90 min/barrel. Residual oil hot 6-8%, cold 8-10%.
Aflatoxin B1 limit <20 μg/kg (EU) / <20 ppb (US). Damaged/moldy kernels must be removed by color sorter or manual picking. Test every batch. One contaminated batch can destroy an entire export shipment.
ModulesSeeing roasters, presses, filtration, storage, and cake handling together sharpens the phase boundary.

Matched to roasted hot pressing at 80-100°C. Faster 30-40 min cycle per 100 kg barrel, oil yield 40-48%, residual oil 6-8%. Highest throughput per hour — the workhorse for bulk edible peanut oil.
For lower-temperature ≤60°C pressing where frame stiffness absorbs higher mechanical stress over a 60-90 min cycle. Oil yield 35-42%, residual oil 8-10%. Suits premium and cleaner-kernel projects.
The stiffest frames for sustained cold pressing or multi-press scale-up. Same 60 MPa hydraulics; the larger frame holds pressure steady and stays true over years of high-stress cold cycles.
Supporting modules
The handoff from roaster to press is where real hourly output is won or lost.
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.
Project boundary
Peanut Hydraulic Oil Press Line: Model Ladder 300-500 and Supporting Modules 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.
Factory model check
When discussing Peanut Hydraulic Oil Press Line: Model Ladder 300-500 and Supporting Modules, pin models to published factory specs — not tonnage alone.
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).
Equipment check
After Peanut Hydraulic Oil Press Line: Model Ladder 300-500 and Supporting Modules 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.
Define pneumatic/plate-frame filtration, tanks, retained samples, and cake offtake before press count. Factory hot lines often use multi-layer paper filters.
Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.
Questions to confirm next
They share the same 60 MPa hydraulic system and 2.2 kW motor. The difference is frame strength and pressure stability: 300/325 suit the faster hot cycle (30-40 min, 80-100°C), while 355-500 absorb the higher mechanical stress of the cold cycle (60-90 min, ≤60°C) without deforming over time.
