Small soybean factory: 5-30 t/d hydraulic, dehulled + flaked + conditioned

First-phase decisions

What a 5-30 t/d soybean line must lock in

• Feed condition: whole bean (need full prep line) or already cracked/flaked (skip prep, save 30-40% capex).
• Dehulling: yes (HiPro meal protein 48-50%, +15-25% revenue) or no (commodity meal 44%, simpler line).
• Press class: 200 ton (5 t/d, 1 unit), 325 ton × 1-2 (10-20 t/d), 325 ton × 3 (30 t/d).
• Crude oil endpoint: settling + filtered bulk oil, OR degumming + RBD refining train, OR handoff to refining contract.
• Meal plan: bagged HiPro 48-50% (premium feed), commodity 44% meal, or food-grade soy flour (defat + grind).

Reference layout (10 t/d)

Worked-out 10 t/d hydraulic soybean configuration

• Cleaning + drying: vibrating screen + magnetic separator + destoner + hot-air dryer (intake 12-13% → 10-11% moisture). Capacity 1-1.5 t/h.
• Cracking + dehulling: corrugated cracker rolls (1-2 mm gap, 4-6 pieces per bean) + aspirator (hull 7-9% removed). Capacity 1-1.5 t/h.
• Flaking + conditioning: smooth roll flaker 0.25-0.35 mm + steam-jacketed conditioner 70-80°C × 30-45 min, moisture 10-11%.
• Hydraulic press: 1-2× 325 ton, 80-100 kg/barrel, 30-45 min/cycle. Yield 12-16% bean weight = 1.2-1.6 t oil/day on 10 t/d feed.
• Filtration: 200-300 mesh plate-frame + settling tank 24 h (1000-2000 L). Add 1-5 μm bag for retail bottling.
• Meal handling: cake breaker + 25/50 kg bagger; or hammer mill + sifter for food-grade soy flour.

What to confirm before scoping Small Soybean Oil Factory

Small Soybean Oil Factory 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 Soybean Oil Press modules stay. Listed on the factory hot-press page — discuss 300/325 first.

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.
• Listed on the factory hot-press page — discuss 300/325 first.

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.
