Hydraulic Oil Press Machine (HN325)
If you're opening your first oil mill and your budget is tight but you still need a hydraulic oil press machine that actually works — this is where most of our customers start. The HN325 is our factory's best-selling hydraulic oil press by volume, and for good reason: it hits the sweet spot between pressing power and price.
The 260mm piston and 850mm stroke deliver 27.78 Mpa at the cake surface — enough to fully extract tea seeds, sesame, groundnuts, rapeseed, and soybeans in a single cycle per batch. We've shipped this exact model to first-time mill owners in Ethiopia, Tanzania, and the Philippines who needed something reliable without over-investing on day one.
One honest note: if you're planning to cold-press walnuts or tiger nuts, look at the HN426 instead. The HN325 wasn't built for shells that hard. But for everything else? It punches well above its weight class. Batch capacity runs 5–100 kg depending on seed type, and the external hydraulic station means you can service it yourself with basic tools — no specialist technician required.

Frequently Asked Questions — HN325
HN325 vs HN355 — how do I choose?
If your main crop is sesame or tea seed and you're watching your startup budget, the HN325 is the right pick. If you're pressing harder shells like rapeseed or peanuts in larger volumes and can spend a bit more, the HN355's extra 35 tons of force and wider piston make a real difference in daily throughput.
What's the daily output with sesame or groundnut?
With sesame using the optional 300mm barrel: roughly 8–12 batches per day for one operator, translating to 400–600 kg of seed processed daily depending on roast quality and operator experience. Groundnut batches are heavier (40–50 kg per load), so expect 6–10 batches per day with slightly longer press cycles.
How much floor space does the HN325 need?
The single-barrel unit occupies 1200×1200 mm (about 1.44 m²) with a height of 2450 mm. Add at least 600–800 mm of clearance around all sides for safe operation, material loading, and maintenance access. The double-barrel version needs 2100 mm along one axis. Plan for a total footprint of roughly 4–5 m² including working space.
Does it come with the hydraulic station included?
Yes. The external hydraulic station (pump, motor, oil tank, valve assembly) ships as part of the complete machine package. It's not a separate purchase. The external design was chosen deliberately so you can inspect, service, and replace components without disassembling the main frame — a big advantage over integrated units when you're operating in areas with limited technician access.
What's the delivery time to East Africa or Southeast Asia?
From our factory in Shandong to major ports like Dar es Salaam (Tanzania) or Djibouti (for Ethiopia): typically 30–45 days door-to-port by sea freight. To Manila (Philippines): 20–30 days. We handle export documentation, crating, and loading. Exact timing depends on current shipping schedules and your port of destination — contact us with your location for a precise estimate.
