Pretreatment work of oil raw materials

Pretreatment work of oil raw materials

In the oil extraction production line, some newcomers often pay more attention to the oil extraction process and ignore the pretreatment part. In fact, doing a good job in the pretreatment of the oil raw materials can not only improve the oil yield, but also prolong the service life of the machine.

The impurities contained in oil raw materials can be divided into three main categories: inorganic impurities, organic impurities and oil-containing impurities.Organic impurities mainly include dust, sediment, stones, metals and so on.Organic impurities mainly include stem and leaf, skin and shell, wormwood, hemp rope and particles. Oil-containing impurities mainly refers to pest seeds,incomplete seeds, heterogeneous seeds and so on.

So before pressing oil, we need to pretreat the oil raw materials. Most of the impurities contained in the oil raw materials do not contain oil itself, which will reduce the oil yield and increase the oil loss. The impurities in the oil raw materials, such as soil, plant stems and leaves, skins and shells, will deepen the color of the squeezed oil, increase the sediment, produce peculiar smell, and reduce the quality of the crude oil. At the same time, the by-products such as oil cake are adversely affected.  

Without pretreatment, hard substances such as stones in oil raw materials will enter the machine in the production process, which will wear and destroy the working parts, greatly shorten the service life of the machine.And it may even lead to production accidents.The long-woven impurities such as wormwood and hemp rope in the oil raw materials are easy to be entangled on the drive shaft of the equipment or block the inlet and outlet of the equipment, affecting the normal operation of the press and causing equipment failure. In the process of transportation and production, the flying of dust in the oil raw materials will cause environmental pollution in the workshop and deterioration of working conditions.

  Therefore, before pressing oil, we should use a professional machine to pretreat oil raw materials.Our company has special sheller and winnowing separator machine If you interested it please contact us.
