One barrel at a time: sizing cottonseed capacity without brochure numbers

Worked examples

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).

Bottleneck

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.

For a real quote

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.

Project boundary

What to confirm before scoping cottonseed Hydraulic Press Capacity

cottonseed Hydraulic Press Capacity 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 Cottonseed Oil Press modules stay. Cottonseed is almost always 300/325 hot press + cook + mandatory refining (gossypol).

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.
• Cottonseed is almost always 300/325 hot press + cook + mandatory refining (gossypol).

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.
