Cottonseed delinting, hull separation, hot pressing, crude-oil refining handoff

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

Gin-side line reference: seed direct from co-located cotton gin (eliminates transport + storage), seasonal 60-120 days/year operation. Flow: 10-30 t/d ginned seed → linter saw → sheller (optional, hull 35-45%) → cook 110-130°C × 30-60 min → grind/stir → 1-3× 325 ton hydraulic press at 80-110°C, 100 kg/barrel, 30-45 min/cycle → yield 14-18% whole seed (1.4-5.4 t crude oil/day) → settling tank 24 h → 200-300 mesh filter → tanker pickup or on-site refining. Cake 6-9% residual oil → bagged ruminant feed.

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.

Equipment scope (10-30 t/d)

Right-sized layout without overbuild

Feed intake (10-30 t/d)

Confirm gin output: ginned + linted (need linter saw) or delinted (skip). Linter saw 500-1500 kg/h capacity. Sheller optional for kernel-rich feed (28-35% yield) vs whole-seed feed (14-18%).

Hot-press section

Steam cooker 1-3 m³ (110-130°C × 30-60 min), grinder 1-3 t/h, 1-3× 325 ton hydraulic press (100 kg/barrel, 30-45 min cycle). Per press = ~1-2 t/h seed = 8-16 t/shift.

Crude-oil + cake

Settling tank 5-15 m³ jacketed (24 h hold) + plate-frame filter 200-300 mesh + tanker loading. Cake breaker + cooler + 25/50 kg bagger 500-1500 kg/h.
