Hydraulic Oil Press Machine — Factory Direct from Haonuo

A hydraulic oil press machine uses hydraulic pressure to extract oil from seeds and nuts. Unlike screw presses that generate heat through friction, hydraulic presses apply uniform static pressure at controlled temperatures, making them ideal for cold pressing premium oils like sesame, walnut, and coconut oil. The process preserves natural nutrients, flavor, and aroma.

The machine uses a hydraulic pump to generate high pressure (up to 75 Mpa) which drives a piston into a barrel filled with prepared oil seeds. The pressure squeezes oil out through a slotted barrel while the compressed seed cake remains inside. A typical pressing cycle takes 8-15 minutes. The microcomputer control system automates the entire process from pressing to cake discharge.

Hydraulic oil presses can process 50+ types of oil seeds including sesame, peanut, coconut, walnut, almond, sunflower, flaxseed, mustard, rapeseed, tea seed, soybean, cottonseed, apricot kernel, and more. Different models are optimized for different seed types — smaller models for sesame and soft seeds, higher-pressure models for hard-shell nuts like walnut and almond.

Oil yield varies by seed type: sesame 42-50%, peanut 38-45%, coconut 55-65%, walnut 50-60%, rapeseed 35-45%, sunflower 40-48%. Haonuo hydraulic presses use a proprietary bar-type slotted barrel design that achieves approximately 2-3% higher yield than traditional drilled barrel presses (based on internal testing, results vary), with residual oil in cake as low as 6-8%.

Contact Haonuo for factory-direct pricing. We offer competitive rates with no middleman markup — saving compared to local distributors (actual savings vary). Pricing depends on the model, barrel configuration (single/double), and customization options.

Cold press operates below 60°C preserving nutrients, natural flavor, and aroma — ideal for premium oils like sesame, walnut, and virgin coconut oil. Hot press involves roasting seeds before pressing, which increases yield slightly but may alter flavor and reduce nutritional value. Hydraulic oil presses are naturally suited for cold pressing because they apply static pressure without friction-generated heat.

Yes, Haonuo hydraulic presses only need 2.2 KW motor power, making them fully compatible with a 5-7 KVA generator. This makes them ideal for areas with unstable or no grid electricity, such as rural Nigeria, Kenya, and other regions across Africa and Southeast Asia.

All Haonuo machines come with a 1-year warranty covering manufacturing defects, plus lifetime technical support. Spare parts are available from stock. Every machine undergoes 48-hour continuous full-load testing before shipment to ensure reliable operation.
