High-efficiency hydraulic oil press | QIE Group cold-pressed technology locks in fresh, nutritious walnut oil

With the modern trend toward healthy eating, high-quality walnut oil is increasingly popular among consumers. Maximizing the nutritional value of walnuts during the oil extraction process is a key concern for every edible oil manufacturer and family oil mill. The hydraulic walnut oil press launched by QIE Group, combined with advanced cold-pressing technology, provides a highly efficient, nutrient-retaining solution for walnut oil production.

Why can the cold pressing process lock in more than 98% of nutrients?

Walnut oil is rich in unsaturated fatty acids, vitamin E, and various active nutritional factors, but high-temperature processing can easily destroy these valuable ingredients. Our independently developed hydraulic oil press uses a low-temperature physical pressing process to achieve a "fresh-locking" walnut oil extraction, preserving both nutrients and aroma.

Why choose QIE hydraulic oil press?

✅ 1. Extremely fast oil extraction: 8-10 minutes of efficient pressing

Our hydraulic oil presses, equipped with a high-pressure hydraulic control system , deliver a single press cycle in just 8–10 minutes, over 50% greater efficiency than traditional mechanical oil presses. This rapid oil output not only saves labor and energy costs, but also significantly increases overall production line profitability.

✅ 2. Flexible adaptation: 20-60 kg single filler

Whether you're working with a small walnut oil processing plant or a family-run cold press, our hydraulic oil presses are flexible enough to handle any application. They can handle a wide range of raw materials, ensuring efficient and continuous operation from small trial runs to full-scale production.

✅ 3. Golden oil yield: patented pressure system breaks through traditional limits

The equipment utilizes patented QIE hydraulic control technology, utilizing staged pressurization and constant pressure maintenance to maximize oil separation efficiency. In actual production, walnut oil yields reach industry-leading levels, enabling customers to achieve higher profits with the same raw material costs.

Core advantages of QIE Group hydraulic oil press

• Food-grade stainless steel pressing chamber: meets food processing standards to ensure the oil is pure and pollution-free.
• Precise pressure control of hydraulic system : Intelligent hydraulic module achieves stable pressure output and extends equipment life.
• One-button operation without training: The intelligent control system automatically completes the pressing and oil return cycles, making it easy for novices to get started.
• Cold pressed fully enclosed structure : reduces oxidation contact and keeps the oil fresh and fragrant.

Food-grade safety design ensures every drop of oil is safe

All our presses utilize 304 stainless steel for the pressing chamber, complying with national food safety standards (GB 4806.9). The hydraulic system features automatic pressure relief, enabling operators to complete routine operations without specialized training, significantly reducing labor costs and the risk of accidents.
