Walnut Oil Pressing Solution

Quick Answer

Yes — the Haonuo hydraulic oil press is built for walnut. Expect 50-62% yield from walnut kernels cold-pressed below 60°C, with residual oil in cake at 5-8%. The HN500 ultra-high-pressure press takes 100 kg per batch at 4-6 batches per hour, producing roughly 2,000-3,000 kg of walnut oil per 8-hour day. The critical rule: keep it cold — hot pressing can destroy 30-40% of the omega-3 content that makes walnut oil worth premium prices.

Walnut Oil Press Overview

Walnut oil is one of the most premium edible oils in the world, prized for its rich omega-3 content, delicate nutty flavor, and numerous health benefits. The Middle East and Central Asia are among the largest consumers of walnut oil, where it is used both as a gourmet cooking oil and in traditional medicine.

Haonuo Machinery’s walnut oil pressing solution is specifically designed for producers who demand the highest quality cold-pressed walnut oil. Our ultra-high pressure hydraulic press technology ensures maximum oil extraction while preserving the heat-sensitive omega-3 fatty acids that make walnut oil so valuable.

What you get from 100 kg of walnut kernels

Typical figures for well-prepared walnut kernels at standard machine settings; actual results vary with seed variety, moisture content and cycle settings. Liters assume an oil density of approximately 0.92 kg/L.

What 100 kg of Walnut Kernels Is Worth

At 4-6 batches per hour, one HN500 presses 3.2-4.8 tonnes of kernels per 8-hour day — roughly $13,000-46,000 of product per day at indicative prices.
