COMMERCIAL HYDRAULIC OIL PRESS MACHINE FOR SMALL BUSINESS

The HN325 uses a hydraulic cylinder to press seed inside an enclosed tabung press. Cleaned, conditioned (and usually roasted) seed is loaded in batches of 20–100 kg; the 325-ton ram applies static pressure for 30–40 minutes (hot) or about 2 hours (cold), squeezing oil through the tabung press's slot walls. Static pressing adds no friction heat, so raw dried seed stays naturally below 60°C.

With hot pressing and full 100 kg batches: roughly 900–1,000 kg per 8-hour shift with a single tabung press, or 1,200–1,400 kg with the double-barrel setup (one tabung press presses while the other is unloaded and refilled). Cold pressing runs slower: about 300–400 kg (single) or 600–700 kg (double). These are estimates from cycle times, not guarantees. Smaller 20–50 kg batches work the same way — handy for testing or niche seeds.

Common oilseeds include sesame, peanut, walnut, camellia (tea) seed, flaxseed, rapeseed, sunflower seed and soybean, among most other oil-bearing crops. Walnut and apricot kernel press well in cold process; for a dedicated hard-shell cold-press business, see the higher-force HN426.

The hydraulic cylinder is machined from 27SiMn alloy steel (GB/T 3077) — the standard steel for high-pressure cylinders — heat-treated and pressure-tested before assembly. The press tabung press is welded from Q690 high-strength steel and nickel-plated inside and out, so no bare carbon steel touches the oil; its strip-slotted walls release oil faster than drilled tabung press. The base frame is Q355B structural steel and the valve block is electroplated for rust protection.

Up to about a ton of hot-pressed seed per day, the double-barrel HN325 is enough. The HN365 (365 t, higher cake pressure) adds force and cuts waiting time between cycles for larger volumes. Send us your seed type and daily target for a throughput calculation.

The HN300 remains in production and shares the hydraulic design and common wear parts with the HN325. Two differences: 300 t force (vs 325 t) and a smaller Ø300 mm tabung press (same 800 mm height), which raises cake pressure to about 42 MPa but holds a smaller batch — about 55–60 kg of crushed seed. Smaller daily batches on a tight budget: HN300. Full 100 kg batches: HN325.

The HN325 is wired for 380V / 50Hz as standard. If your country runs on 415V (common in Nigeria and other West African grids), order the 415V version — tell us your local standard when requesting a quote.

Payment: 30% deposit with your order, 70% balance before shipment. Shipping: quoted FOB by default (CIF to your port on request), by sea. After the 15–25 working day build time, ocean transit typically adds about 4–6 weeks to West African ports depending on destination and schedule. Full shipping documents are provided with every shipment.

Yes — tabung press diameter (300–630 mm), height and food-grade stainless steel are available as custom options. Custom configurations take 30–45 days to build; standard ones 15–25 working days.
