Characteristics of plant oil press

---

The characteristic of Sesame Oil Press is that the equipment pressure is static pressure, the mechanical friction of the oil is very small, the oil is very clear, and the oil can be directly consumed without any treatment, which is convenient and safe. This device has high-pressure and high-temperature pressure oil, and almost all oil can be pressed out of the oil. The hydraulic press has the characteristics of high efficiency, environmental protection and energy conservation, high product added value, no loss, no noise, no need for heating or adding any chemical raw materials, no need for clean oil, easy operation, no worn parts, and long service life.

Product features of hydraulic walnut oil press machine

The hydraulic oil press is designed based on the principle of Basque hydrodynamics, i.e., inside a sealed container, the pressure change at any point in the liquid will be transmitted to all directions with the same pressure. Through the hydraulic system, the power of the small diameter high pressure pump is transformed into a huge pressure inside the press chamber, realizing the physical extrusion of the oil material to produce oil.

• Highly controllable pressure: the pressure is adjusted by the hydraulic pump station, adapting to different oil characteristics (such as avocado, sesame, peanut, walnut, etc.).
• Compact structure: vertical or horizontal design, small footprint (10-20 square meters can meet the needs of small oil mills), suitable for space-limited scenes.

Core Advantages of Korean Oil Press

---

• Enhance the oil yield
• adopts multi-stage progressive pressurization technology, the pressure of the press chamber can reach 45-60MPa, with infrared temperature control system to automatically adjust the pressing temperature (70-100℃), so that the fission and separation of the oil material is more thorough, and the oil yield is increased by 10%-15% compared with the traditional equipment. For example, the oil yield of avocado pulp can reach 50%-60%, and the residual oil rate of oil cake is less than 10%.
• Pure oil quality
• Low-temperature pressing: control the temperature at 40-60℃ to avoid high temperature destroying the active ingredients of oil (such as monounsaturated fatty acids, vitamin E), and retain the natural flavor and nutrition.
• Multi-stage filtration: integrated rotary evaporation, vacuum degassing and other processes to remove impurities and gums, the oil is clear and bright, in line with food grade standards.
• Increased durability and utility
• Excellent material: the main parts (such as piston, hydraulic cylinder, squeezing assembly) are made of high carbon steel or imported silicon sawn steel, high frequency quenching, heat-resistant treatment, high hardness, good abrasion resistance, service life of up to several decades.
• Automatic protection: Equipped with pressure gauge, temperature control regulator, relief valve and other safety devices, real-time monitoring of pressure and temperature to prevent overpressure or overheating damage to the equipment.

What kind of oil can be extracted from oil presses

---

This machine is the perfect choice if you work with high-value seeds and nuts. 

A hydraulic oil press is a specialized tool. It is not designed to process large volumes of common seeds like soybeans or rapeseed. That is the job of a screw press. Instead, this machine shines when used with raw materials where the final oil’s unique flavor, aroma, and nutritional profile are the main selling points. It is all about quality, not quantity. Your business plan should focus on creating a premium product.

• Sesame Seeds: This is a classic application. A hydraulic oil press is the best sesame oil press for producing light-colored, mild, and highly aromatic virgin sesame oil. This type of oil is very different from the dark, toasted oil and sells for a higher price.
• Nut Kernels: Walnuts, almonds, hazelnuts, and macadamia nuts are perfect. The gentle process preserves their delicate, nutty flavors, creating gourmet oils that chefs and food lovers seek out.
• Specialty Health Seeds: Flaxseed, perilla seeds, and pumpkin seeds are rich in healthy fats. Using a hydraulic press is the only way to preserve these delicate nutrients and sell the oil as a health supplement.
• Avocado and Olives: This press is ideal for the first cold pressing to produce true “extra virgin” oil, the highest possible grade.

The use and maintenance of sesame oil press machine

---

• Pay attention to maintaining cleanliness and hygiene. Before and during pressing, it is necessary to pay attention to the cleanliness of the piston surface, and promptly clean the dirt and oil adhering to the piston surface.
• Pay attention to maintaining a reasonable pressure. When using the oil pump to pressurize, do not act too quickly or forcefully to prevent hydraulic components from being damaged by oil impact. When reducing pressure, the return valve must be opened first. When the oil in the cylinder flows back into the tank, the valve should be slowly opened to avoid a sudden drop in pressure.
• During operation and use, attention should be paid to the operating condition of the machine, and vulnerable parts (such as cups, sealing devices, steel balls, pistons, etc.) should be inspected regularly, repaired and replaced in a timely manner. Loose nuts should be tightened, and the machine should be regularly inspected and cleaned.

How to turn waste into treasure from soybean residue after oil extraction

The soybean residue after oil extraction can be made into nutrient rich organic fertilizer, which can reduce the generation of waste and be convenient for farmers to use. Meanwhile, due to the high content of protein in soybean residue, it can also be processed and crushed to produce foods such as soybean residue cakes and meat, which have certain economic value.

The development trend of hydraulic oil press

---

The market for cold pressed oils continues to grow, and technology is making it easier for businesses. As we move into 2025, the consumer demand for authentic, unprocessed foods is stronger than ever. This is pushing businesses to explore new and exotic oils. We are seeing increased interest in pressing things like moringa seeds and sea buckthorn for the cosmetic industry.

The technology for the hydraulic oil press is also evolving to meet these needs. Newer models now feature more advanced digital control panels. These panels allow you to save specific pressure profiles for different seeds. This makes it easy to get perfectly consistent results from batch to batch with less operator skill. We are also designing more compact and integrated systems. These systems combine the press with a small filter, making it a complete pressing and clarifying station for small businesses. This all-in-one approach lowers the overall footprint and simplifies the workflow for newer businesses entering the premium oil market.
