The refining process of edible oil occupies an important position in modern food industry, and its purpose is to improve the quality and safety of oil products. Some key principles should be followed when selecting the appropriate refining process to ensure that the production process is efficient, environmentally friendly and economical.

First, the refining process should maximize the oil output and minimize the loss in the refining process. This means optimizing the process conditions in each step to reduce the waste of raw materials and energy. For example, in salad oil production, physical refining is often preferred because it can effectively reduce the emissions of reactants and is more environmentally friendly than chemical refining.

Second, the main refining steps include degumming, deacidification, decoloration, deodorization and dewaxing. These steps have their own unique functions and requirements. Degumming is mainly used to remove phospholipids and impurities in oil, deacidification is mainly to remove free fatty acids, and decoloration is to remove pigments and other trace components. Deodorization step is to remove odorous substances in oil by steam distillation, and the final dewaxing step is used to remove wax with high melting point, so as to improve the transparency and stability of oil products.

Besides, the refining process should be as simple, efficient and innovative as possible. The equipment design should be concise and highly mechanized, continuous and automatic, so as to reduce labor intensity and improve production efficiency. At the same time, the adaptability of equipment configuration and technology is strong, so as to meet the processing needs of different types of oil.

In a word, when selecting edible oil refining process, many factors such as output, loss, environmental protection, equipment design and process adaptability should be considered comprehensively. By optimizing each link, we can not only improve product quality, but also realize sustainable development, which meets the requirements of modern industry for green production. This refining process can not only meet the market demand, but also bring greater economic benefits to enterprises.
