What is the working principle of a oil presses

The working principle of a herb oil press is mainly to compress and extract oil crops in the press chamber through the pressure generated by the hydraulic cylinder. When the pressure of the hydraulic cylinder reaches a certain value, the gap between the squeezing strips will become smaller and smaller, and the oil crops will gradually be compressed, ultimately squeezing out the oil. By injecting high-pressure liquid into the oil extraction chamber, crops such as walnuts are squeezed out of their cells by the action of high-pressure liquid. The hydraulic oil press is easy to operate and has a high oil output rate.

What are the Key Components of a High-Quality Hydraulic Oil Press?

A high-quality machine is strong, safe, and made with the right materials. When you invest in a hydraulic oil press, you are buying a long-term asset for your business. It needs to be reliable. As a manufacturer, we build our machines to last and to perform perfectly. There are three critical areas you must inspect when choosing a machine.

The Hydraulic System: The Engine of Your Press

• This is the heart of the machine. The hydraulic system includes the electric motor, the hydraulic pump, and the control valves. This system must be able to generate and hold very high pressure for a long time without failing. A good machine uses a reliable, industrial-grade pump. It also has precise controls that let you adjust the pressure. This is important because different seeds need different amounts of pressure for the best results. A reliable power system ensures you can produce consistently, day after day, without unexpected downtime. This consistency is essential for meeting your customers’ orders and building a dependable brand.
• The Press Barrel and Piston: Where Quality is Made
• This is the most important part for your product’s quality. The press barrel and any part that touches the seeds or oil must be made of food-grade stainless steel. We cannot stress this enough. Some cheaper machines might use regular steel, but this can rust and contaminate your oil, ruining its taste and value. Stainless steel is completely neutral. It does not react with the oil, so it preserves the pure flavor. It is also very easy to clean thoroughly, which is essential for meeting food safety standards. With our machines, you can be sure you are creating a pure and safe product. This is a key feature of a professional cold press oil expeller.

What kind of oil can be extracted by Korean hydraulic oil press machine

The pressing range of the hydraulic oil press:

hot pressed oilseeds: sesame, flax, peanut, wheat germ, corn germ and other

cold pressed oilseeds: pine seeds, almonds, olives, walnuts, camellia seeds, etc; And traditional Chinese medicine, Sichuan pepper, mustard seeds, perilla, etc;

The finished oil is of good quality and pure physical pressing, with a high oil yield. During the cold pressing process, no temperature is generated, and the organic components of the material are not damaged. The oil quality is good, with less impurities, high cake value, and high efficiency. It can be completed within 8 minutes from loading to cake discharge. The appearance is exquisite, and the operation is simple (one person can operate multiple machines)

Is the oil squeezed by the hydraulic oil press machine edible

Whether the oil extracted by the almond oil press machine can be consumed mainly depends on the following

factors:

• Quality of raw materials: The raw materials extracted by the oil press must be safe and pollution-free oil crops, such as peanuts, soybeans, rapeseed, etc. If there are quality issues with the raw materials themselves, such as mold, contamination, etc., the extracted oil will also have safety risks.
• Cleanliness of the oil press: The oil press needs to be thoroughly cleaned and disinfected before pressing to ensure that the extracted oil is not contaminated. If the oil press is not clean, it may result in impurities or bacteria in the extracted oil, which can affect food safety.
• Temperature control during oil extraction process: Temperature control during oil extraction process is very important. Excessive temperature may lead to the loss of nutrients in oil crops and the production of harmful substances. Therefore, strict temperature control is required during the oil extraction process to ensure that the extracted oil is both safe and nutritious.
• Treatment of extracted oil: The extracted oil also needs to go through processing steps such as filtration and refining to remove impurities and harmful substances. These processing steps can further improve the quality and safety of the oil.
• If the raw materials used in the hydraulic oil press are of good quality, the cleanliness of the oil press is high, the temperature control during the oil pressing process is appropriate, and the extracted oil has been properly treated, then the extracted oil can be safely consumed.

Vertical Oil Press Product Advantages

• Improve 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.
• Enhanced practicality
• 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 wear resistance, service life can be up to several decades.
• Automatic protection: Equipped with pressure gauge, temperature control regulating gauge, relief valve and other safety devices, real-time monitoring of pressure and temperature to prevent overpressure or overheating damage to the equipment.

What is the use of waste after hydraulic pressing walnut oil

The main waste generated by the hydraulic oil press when pressing walnuts is walnut oil residue. These oil residues are the remaining residue after oil extraction. Oil residues can be used as food processing materials, containing nutrients such as protein and fat in their nutritional components. They can also be used as feed for aquaculture of fish, shrimp, crabs, and other aquatic products. It contains a large amount of oil and is a high-quality organic fertilizer that can also be used for crop cultivation.

Is a Hydraulic Oil Press the Right Choice for Your Seeds?

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.

• Here are the best types of raw materials for a hydraulic oil press:
• 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.

Practical Tip for You: No matter which seed you use, its moisture content is very important. The seeds cannot be too wet or too dry. You usually need to dry the seeds to an optimal moisture level before pressing to get the best results.

Frequently Asked Questions

Question 1: What is the main difference between a hydraulic press and a screw press?
The main difference is the method. A hydraulic oil press uses slow, static pressure in batches, which generates no heat. A screw press uses continuous grinding friction, which generates heat. Hydraulic presses are for premium cold pressed oil, while screw presses are for high-volume hot pressed oil.

Question 2: How much oil can I extract with a hydraulic oil press?
The oil yield from a hydraulic press is often slightly lower than from a hot screw press. However, the business goal is different. You extract less oil, but the oil you do get is much higher quality. This allows you to sell it for a much higher price, leading to greater profit per bottle.

Question 3: Does the hydraulic oil press need a lot of maintenance?
No, a hydraulic oil press has very low maintenance needs. It has very few moving parts compared to a screw press. The main tasks are regular cleaning of the stainless steel barrel and checking the hydraulic fluid level. Its simple design makes it very reliable.
