This page is about the thermal window that makes hot peanut oil smell right and press steadily; it is not the general route page.
Set peanut roasting temperature, residence time, loading rhythm, kernel moisture, aroma target, and press-ready discharge window before pressing.
Roast level gives the oil its commercial character.
Waiting too long after roasting hurts color and smell.
The roast window should lead straight into stable hydraulic loading.
Roaster capacity and discharge rhythm should be fixed before the press is quoted.
Heat control
Hot pressing needs roaster capacity, heating method, and discharge rhythm defined before press sizing.
Route handoffRoute choice affects filtration, settling, storage, and cake handling, not only press class.
Project boundary
Peanut Roasting and Conditioning Window 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 Roasting and Conditioning Window, 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 Roasting and Conditioning Window 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.
