Peanut oil is one of the mainstream edible oils in China, which is rich in nutrition, good taste and has many product types. According to the different processing technology, it is divided into pressed peanut oil, leached peanut oil and peanut crude oil, and pressed peanut oil is divided into cold-pressed peanut oil, fragrant peanut oil, refined peanut oil and other products. In order to increase the oil yield of peanuts and improve the yield, large peanut oil factories will also use the pre-pressing-leaching process to produce peanut oil.
Peanut raw materials in the planting, receiving, transportation, storage process will be affected by the environment, temperature, pollution and other aspects, resulting in the subsequent processing of peanut oil in the presence of certain impurities and substances that are not good for the human body, such as aflatoxin and other mold pollution, has a great impact on human health, so the peanut oil pressed peanut oil also needs to be refined to remove impurities and harmful substances in the crude oil, in order to ensure its quality and food health, safety, before it can be sold as a commodity in the market.
The refining of edible oil is mainly to remove oil-soluble impurities, fat-soluble impurities, pigments, harmful elements, etc., but the transition refining will lead to the removal of nutrients originally existing in the oil, therefore, the refining of edible oil should not only separate the impurities that are unfavorable to the human body, but also retain the nutrients such as vitamin E and sterols in the oil as much as possible, reduce the addition of too many substances to the crude oil to destroy the nutrients of the oil itself, improve the oxidation stability of the refined oil in the refining process, and reduce the production of trans fatty acids. To avoid the occurrence of oil color return and improve the refining yield of edible oil, this has certain requirements for the technology and process of refining equipment manufacturers.
In the process of oil refining, in order to achieve good refining results, the quality of refining equipment and mature refining process are the key points. The refining equipment can reduce the loss of neutral oil in the refining process, improve the oil yield of refined oil, and the refining process is the key to improving the quality of oil and food safety. This requires oil mills to choose machinery and equipment with both quality and technology, so as to achieve good production results.
Refining equipment is the key equipment for oil mills to produce edible oil that meets the requirements of the national standard, the quality and service life of the equipment is the focus of most oil mills, when choosing equipment, the manufacturer's technical strength, after-sales service, customer reputation, etc. are one of the factors considered when the oil mill chooses the equipment manufacturer.
