Is olive oil cold pressed oil
Olive oil is directly cold pressed from fresh olive fruit, without heating or chemical treatment, thus preserving its natural nutritional components. Cold pressing usually refers to pressing at a lower temperature (40-60 ℃) to extract vegetable oil. And olive oil is obtained by cold pressing using this physical method, which preserves 100% of its nutrients. This is also one of the reasons why olive oil is considered a very suitable oil for human nutrition. It is recommended to use FuDe Machinery’s olive oil press for olive pressing:
- During the oil pressing process, the olive fruit is fed into the Fude oil press. As the screw rotates and advances, the gap between the screw and the press chamber gradually narrows, increasing the density of the oil and pressure, thereby damaging the oil cell tissue and causing the oil to overflow from the oil line.
- Characteristics and advantages
- Specialization: The olive oil press is mainly suitable for extracting olive oil, and its design and process have been optimized based on the characteristics of the olive fruit to ensure excellent quality of the extracted olive oil.
- Material selection: Olive oil presses are usually made of high-quality materials such as stainless steel or ceramics, which do not undergo chemical reactions with olive fruits during the oil pressing process and can maintain the original flavor and nutritional value of olive oil well.
- Low temperature extraction: In order to ensure the full retention of nutrients in olive oil, olive oil presses usually use low-temperature extraction. This method can reduce the oxidation reaction of olive fruit during the extraction process, thereby retaining more nutrients and flavor substances.
- Efficient and energy-saving: Modern olive oil presses focus on high efficiency and energy conservation in their design. By optimizing the oil pressing process and equipment structure, the efficiency of oil pressing and energy utilization have been improved.
- Type and Structure
- There are various types of olive oil presses, including hydraulic presses, screw presses, etc. Different types of olive oil presses have slight differences in structure and function, but the basic principles are the same. Taking the spiral oil press as an example, it mainly consists of three parts: the main engine, the automatic feeding device, and the vacuum filtration. The host part includes key components such as the press screw and the press chamber, which are responsible for extracting oil from olive fruits; The automatic feeding device is used to feed olive fruits into the oil press; The vacuum filtration section is used to filter and purify the extracted olive oil.
- Usage and maintenance
- Preparation before use: Before using the olive oil press, it is necessary to clean and inspect the equipment to ensure that it is in good condition. At the same time, it is necessary to prepare an appropriate amount of olive fruit as raw material.
- Operating standards: When operating an olive oil press, it is necessary to follow the operating standards and safety requirements. For example, it is necessary to control the pressure and temperature parameters of the oil press to ensure stable quality of the extracted olive oil.
- Maintenance: Regular maintenance of the olive oil press is key to maintaining equipment performance and extending its service life. Maintenance work includes cleaning equipment, inspecting component wear, replacing damaged parts, etc.
- Market and Application
- With people’s pursuit of a healthy diet and the increasing demand for olive oil quality, the demand for olive oil presses in the market is constantly increasing. At present, olive oil presses have been widely used in olive oil manufacturers, food processing enterprises, and personal households. Meanwhile, with the continuous advancement of technology and the continuous development of the market, the performance and quality of olive oil presses are also constantly improving and perfecting.
- In summary, olive oil press is an efficient, energy-saving, and specialized mechanical equipment that can effectively maintain the original flavor and nutritional value of olive oil. In the process of use and maintenance, it is necessary to follow operating procedures and safety requirements, and regularly carry out maintenance work to ensure equipment performance and extend service life.
