Description

Technical Field

[0001] The invention relates to the technical field of purification devices, in particular to a linseed oil purification device. Background Art

[0002] The production process of linseed oil is generally divided into hot pressing, cold pressing and leaching. Hot pressing refers to the oil produced by physical pressing after the oil crop is fried or steamed at high temperature. It is a relatively traditional pressing process with a high oil yield. Cold pressing refers to the plant oil extracted under low temperature conditions with huge physical mechanical pressure, so it is called cold pressing. Without the traditional high-temperature frying or steaming process, the oil is still distributed in the undeformed protein cells and contains a very rich amount of linseed inherent components. The leaching method is to use organic solvents, such as gasoline, ethanol, etc. to extract oil, soak the oil raw materials, and then extract them at high temperature to extract the oil. The leaching process can extract almost all the oil in the oil, with very high economic benefits. It is the most popular processing method in the modern oil industry. Regardless of the above method, the linseed oil prepared needs to be purified. The current purification equipment has the defects of low purification efficiency, slow purification speed, and complex purification process for linseed oil. Summary of the invention
