Cottonseed quote guide: six fields close the loop in one round

Six required fields

What turns an inquiry into a fast cottonseed proposal

• Feed: linted (need linter saw or acid delinter) or pre-delinted; whole seed (yield 14-18%) or dehulled kernel (28-35%); oil + moisture + gossypol lab data.
• Scale + cadence: 1-3 t/d pilot / 10-30 t/d gin-side seasonal / 50-100 t/d industrial mill year-round. Operating days/year and shifts/day.
• Press class: 200-325 ton × 1-10 units, 100 kg/barrel, 30-45 min/cycle, jacket 80-110°C.
• Refining scope: sell crude oil to refinery (no NBD onsite, save $200-400k capex), or build NBD train (degum + neutralize + bleach + deodorize 240-260°C) for finished retail oil.
• Cake/by-product plan: ruminant feed bagged 23-28% (whole-seed cake) or 41-44% (decorticated meal); hulls feed/fuel/board; linters cellulose.
• Compliance: free gossypol <0.045% (FAO/WHO + FDA + EU + GB), FFA <0.1%, peroxide <2, organic, Halal, Kosher.

Site data

Attachments that prevent rework

• Workshop drawing: m² × ceiling height (5 m for press hall + refining), drainage, fire exits, fire safety class for linter dust.
• Utility readings: 380V/50Hz (or 480V/60Hz US) available kW (200-500 kW for 30-100 t/d), boiler steam capacity (1-3 t/h), water (jacket cooling + cleaning), compressed air.
• Existing equipment: linter saw, sheller, cooker, press, settling tank, refining train — capacity, model, age, condition.
• Seed COA: oil content (18-22% whole / 35-45% kernel), moisture, FFA, free + bound gossypol, lint %, hull %.
• Project scope: crude-oil seller (gin-side simple) / refined retail brand (full NBD + bottling) / export (compliance + container logistics) — drives capex 5-10×.

What to confirm before scoping Cottonseed Quote Guide | Feed Status, Scale, Refining, Cake, Compliance

Cottonseed Quote Guide | Feed Status, Scale, Refining, Cake, Compliance 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.
