Seed: walnut Form: whole / kernel / roasted / dried kg per shift: ____ hours/shift: ____ Route: hot / cold / not sure Product: crude / filtered / bottled / export Cake: feed / food flour / unknown Country + city: ____ Power: ____ V / ____ Hz / phases Existing equipment: ____ Photos: seed + workshop (attach)

Why factories ask this

Incomplete RFQs only get price ranges

• Without kg/shift we cannot count 325 vs multi-press lines.
• Without hot/cold we cannot choose 300/325 vs 355–500.
• Without cake path we mis-size discharge and storage.
• Without country we miss voltage, logistics, and compliance notes.
• Photos cut one round of clarifying emails.

Before you send

Size capacity and process family, then paste the checklist

After you send

What a good reply should contain

• Recommended process family (hydraulic batch vs other).
• Model class (e.g. 325 hot or 355–500 cold) and rough press count.
• Must-have modules: clean, roast/cook, filter, tanks, fill.
• Open questions still blocking a firm quotation.
• Optional: machine-only price band vs full line discussion.

What to confirm before scoping walnut Oil Press Inquiry Checklist

walnut Oil Press Inquiry Checklist 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 Walnut Oil Press modules stay. Factory cold-press page lists this oilseed — prioritize 355–500 (370–630 ton), pure press ~2 h/barrel.

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.
• Factory cold-press page lists this oilseed — prioritize 355–500 (370–630 ton), pure press ~2 h/barrel.

Equipment check

Buying guides 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.
