What is the working principle of a hydraulic oil press

The working principle of a hydraulic 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 materials are suitable for hydraulic oil presses

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)

Walnut oil press

Whether the oil extracted by the hydraulic oil press can be consumed mainly depends on the following factors:

1. 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.
2. 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.
3. 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.
4. 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.

What are the advantages of hydraulic oil press

The oil press combines traditional pressing principles with modern technology. Compared with ordinary oil presses, it has high efficiency, environmental protection and energy conservation, high product added value, no loss, and no noise. Physical pressing does not require heating, no chemical raw materials are added, no clear oil is required, easy to operate, no vulnerable parts, and a long service life. The biggest advantage of a hydraulic oil press is that the equipment pressure is static pressure, and the mechanical friction of the oil is minimal. The oil squeezed is very clear and can be consumed directly without any treatment, which is convenient and safe.

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.
