Capacity is barrels × cycle time × presses — not model number alone

Example: 8-hour hot shift on 325 class

If one press averages about 5–6 two-barrel cycles in 8 h (~1.5 h per 2 barrels with loading), feed is roughly 10–12 barrels × up to 100 kg ≈ 1.0–1.2 t seed/shift per press (less for sesame ~30 kg/batch). Five presses in parallel approach multi-ton/day when pretreatment keeps up — matching factory peanut line stories (pre-press ~500 kg/h feeding multiple 325s).

Press count is useless if roasting or cleaning cannot keep up

• Hot routes need cooker/roaster capacity ≥ press cadence (often 2× barrel weight ready).
• Cold routes need clean, graded feed and tank space for longer cycles.
• Filtration and cake handling must match peak oil and cake discharge, or the press waits.
• Price bands (machine only, 2026 guide): hot 300/325 about US$2000-5000; cold 355 about US$4000-7000; large cold 400–500 about US$8000-15000+ — line cost is higher with prep + filter + fill.

Numbers that let us count presses

• kg seed per shift and hours per shift.
• Hot or cold route and target residual oil story.
• Whether feed is 100 kg-class powder or fine seed (~30 kg sesame style).
• Existing cleaners, roasters, filters, and power (kVA).
• Country and whether output is shop retail, bottled brand, or bulk drums.

What to confirm before scoping walnut Hydraulic Press Capacity: Barrels per Shift and How Many Presses

walnut Hydraulic Press Capacity: Barrels per Shift and How Many Presses 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.

Match hot / cold models to factory hard data

When discussing walnut Hydraulic Press Capacity: Barrels per Shift and How Many Presses, 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).

• 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.

Buying guides needs to land in equipment interfaces

After walnut Hydraulic Press Capacity: Barrels per Shift and How Many Presses 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.
