365 Ton Vertical Hydraulic Oil Press (HN365)
The HN365 is the new-generation model that takes over from the HN355. It keeps the same machine class mill owners already know, but rebuilds it around a reinforced vertical frame of 3 cm high-strength steel plate, alternating double-station barrels, and a modern integrated cartridge hydraulic pack. The rated pressing force is 365 tons, with the cake surface pressure reaching 30 MPa per square centimetre. The vertical layout makes this oil extraction machine easy to load and unload in continuous batch operations.
This model was drawn up for medium and larger mills that have gone as far as a 325-class machine will take them. The extra force earns its keep on hard oil-bearing materials โ walnut, camellia and flaxseed finish more thoroughly, so less residual oil stays locked in the cake. Because the cylinder pushes straight down through a vertical frame, pressure lands evenly, cakes form cleanly, and the frame keeps its accuracy through long high-pressure runs instead of flexing.
Two engineering details matter for buyers overseas. The two stations take turns: one barrel presses while the other is loaded and emptied, so the machine runs a full shift with almost no idle time. And the motor starts through a star-delta (Y-Δ) circuit, which softens the inrush current โ a real advantage on weaker grids or generator power. Barrel interior and oil outlet are nickel-plated, so plain carbon steel never touches the oil.

Frequently Asked Questions — HN365
What exactly is the HN365, and how does it differ from the HN355?
It is the upgraded successor in the same class. The machine keeps the same pressing category but moves to a reinforced vertical frame cut from 3 cm high-strength steel plate, a double-station alternating barrel arrangement, and an integrated cartridge-valve hydraulic system. Rated force is 365 tons and cake pressure is 30 MPa per square centimetre, so hard seeds finish more completely than on a 325-class press while the machine keeps running through the whole day.
Which oilseeds is this machine built for?
Both soft and hard crops are covered — peanut, sesame, rapeseed, sunflower seed and soybean on the soft side, and walnut, camellia tea seed, flaxseed and almond among the hard seeds. Buyers moving up from a 325-class press usually step to the HN365 once they are pressing a larger share of hard seeds or chasing higher daily throughput.
Can the same machine do both hot and cold pressing?
Yes. Pressure, stroke, holding time and the speed at which pressure rises are all adjustable to suit the process. Hot pressing after roasting lifts yield and produces a fuller aroma; cold pressing keeps heat low for premium-grade oil. Flipping between manual and semi-automatic control takes one button.
Why does the double-station layout matter?
With two stations taking turns, the operator fills and empties one barrel during the other station's pressing cycle. There is no dead time while the machine waits to be loaded, so daily production climbs well beyond what a single-barrel press can manage — yet the compact vertical design means it does not occupy twice the floor space.
Will it run on the electricity supply in my country?
The electrical system is configured to your local three-phase standard at no additional charge — for instance 415V 50Hz in Kenya or 380V 60Hz in Saudi Arabia. Star-delta reduced-voltage starting keeps the inrush current gentle, which helps on weak mains and generator supply.
What happens after I order — lead time and payment?
Production begins against a 30% T/T deposit, and the remaining 70% is settled before the machine leaves the factory. Standard builds are normally finished within 15 to 25 working days, with the confirmed loading week written onto the proforma invoice. We trade FOB Qingdao, leaving ocean freight and destination charges to your own forwarder.
