10-30 t/d gin-side cottonseed: seasonal hot-press, crude-oil to refinery

Gin-side fit

When a 10-30 t/d gin-side line makes sense

• Co-located gin supplies 1500-5000 t/season (60-120 day) → 10-30 t/d cottonseed feed without external logistics.
• Crude oil sold to regional refinery (no on-site refining capex) or shipped as crude bulk → minimum tank volume 50-150 m³.
• Steam supply: boiler 0.5-1.5 t/h for 10 t/d, 1.5-3 t/h for 30 t/d. Power: 380V/50Hz, 80-200 kW. 2-4 operators per shift.
• Cake handling area: 50-100 m² + bagger + ruminant-feed buyer pre-arranged. Hulls: 50-100 m² for boiler fuel or particle-board sale.

What to confirm before scoping 10-30 t/d Cottonseed Gin-Side | 1-3× 325 Ton Press, Yield 14-18%, Capex $80-150k

10-30 t/d Cottonseed Gin-Side | 1-3× 325 Ton Press, Yield 14-18%, Capex $80-150k 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

project scope 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.
