I’ve walked a few shop floors in Dingzhou City, Hebei Province—where a surprising cluster of oil machinery makers still weld by hand at 7 a.m.—and the Popular Commercial Oilseed Crushing Machinery Oil Expeller Press Machine pops up again and again in conversations with small refineries and agro co-ops. It’s a workhorse—nothing too flashy, but it keeps pressing while others cool off.
Demand swings toward multi-crop flexibility—soybean one week, sunflower and rapeseed the next—plus lower kWh per ton and easier sanitation. Automation is creeping in (PLC touch panels), but to be honest, operators still value a machine they can fix with common tools. Many customers say stable residual-oil rate and quick changeover now beat sheer peak capacity.
| Model | Commercial screw press (hot/cold) |
| Throughput | ≈ 80–250 kg/h (real-world use may vary by seed, prep, moisture) |
| Main motor | 7.5–18.5 kW, 380V, 50Hz (custom voltages on request) |
| Screw/press cage | Alloyed 45# steel, surface nitriding; replaceable wear segments |
| Residual oil rate | ≈ 6–8% (soy), 5–7% (rapeseed), 6–9% (sunflower) after hot pressing |
| Noise | ≤ 78 dB(A) at 1 m (ISO-like site measurement) |
| Dimensions / Weight | ≈ 1600×700×1400 mm / 450–900 kg (by configuration) |
| Certifications | ISO 9001; CE (Machinery Directive) |
Materials: soybean, rapeseed/canola, sunflower, peanut, sesame, cottonseed (after decortication), and some niche kernels.
Methods: cleaning and de-stoning → crushing/flaking → conditioning at 60–110°C (hot press) → mechanical pressing → crude oil filtration (screen + plate-frame) → optional refining.
Testing standards: oil yield per AOCS methods; residual oil in cake via Soxhlet; noise and vibration checks; run-in at load for 8 hours. Typical service life of key wear parts: 8,000–12,000 hours, depending on kernel abrasiveness and operator discipline.
Real test snippets: soybean at 10% moisture, 95°C conditioning yielded 6.7% residual; rapeseed hovered ~5.9%. Your mileage will vary with seed prep.
| Vendor | Certs | Lead time | After-sales | Price band |
|---|---|---|---|---|
| Dingzhou maker (this model) | ISO 9001, CE | ≈ 15–25 days | Local install + video support | Mid |
| Brand B (India) | CE | ≈ 25–35 days | Service agents in-region | Mid–High |
| OEM C (Turkey) | ISO 9001 | ≈ 20–30 days | Email/parts only | Mid |
Screw and cage alloys for abrasive seeds; heater bands and PID temp control; food-grade gaskets; stainless covers; PLC with recipe presets; special voltage/frequency; explosion-proof motor for dusty plants.
Customer feedback sounds similar: “not fancy, but steady,” and “spares are easy to source.” Honestly, that reliability is the headline.
Built to ISO 9001 QMS; CE Machinery Directive; routine FAT includes yield checks, vibration, insulation resistance, and safety interlock validation. Packaging follows GB/T 191 icons; instruction manual references AOCS test methods for oil yield verification.
