Difference between Ancient Pressing and 5S Pressing

Ancient pressing and 5S pressing are two different methods of oil extraction, they differ in process, principle and application.

1. Ancient Pressing:

- Process: Ancient Pressing is a traditional method of oil extraction, which usually uses traditional pressing equipment, such as oil presses or hand-pressing tools. In this method, raw materials (e.g. oilseeds, nuts, etc.) are put into the press and pressed by mechanical force or gravity to separate the oil from the solid residue.

- Principle: The ancient method of pressing relies primarily on physical pressure to extract oil. During the pressing process, the oil in the raw material is pushed out from the solid residue by pressure, and then separated by means of a strainer, etc.

- The principle: The ancient press relies mainly on physical pressure to extract the oil.

- Application: The ancient method of pressing is mainly used in small-scale or traditional household or rural production, and is commonly used to extract vegetable oils, nut oils, and so on. This method is generally a relatively simple process but has a low yield.

2. 5S Pressing:

- Process: 5S Pressing is a modernized method of oil extraction, usually using professional oil presses or equipment. The method consists of five steps: Soften, Shear, Squeeze, Separate and Stabilize. These steps cover pre-treatment, extraction, separation, purification and preservation.

- Principle: 5S pressing uses mechanical forces, chemical treatments and high temperatures to improve the efficiency and quality of oil extraction. It uses different process steps and conditions such as crushing, heating, steaming, soaking, and centrifugation to maximize the extraction of fats and oils and to separate other impurities.

- Application: 5S pressing is commonly used in industrial production for large-scale oil and fat extraction and production. This method typically offers high efficiency and throughput, and allows control of temperature, time and other parameters of the pressing process.

It is important to note that different regions and industries may have different methods and names for oil extraction. Ancient pressing and 5S pressing are just two of the common examples, and each method has its own applicable situations and advantages and disadvantages. In specific applications, it is necessary to choose the appropriate oil extraction method based on factors such as production scale, process requirements and economic considerations.
