ZHENGZHOU QI'E GRAIN AND OIL MACHINERY CO., LTD. is a large-scale private enterprise specializing edible oil refinery plant suppliers in the production of grain and oil machinery and equipment, scientific research, manufacturing and sales. The company cooperates with Henan Institute of Mechanical Design and Research, Henan University of Technology (WFP) In the oil machinery, protein preparation, phospholipid extraction and other aspects of the new technology research and development and application，and
it's powerful edible oil refinery plant suppliers.
Different origins of the phospholipids and other harmful substances produce in edible oil refinery plant, the refining is carried out in a few steps under different conditions. According to the different oil, refining process is divided into: degumming, neutralization, decolorization, wintering, deodorization and other steps, we can according to the varieties of crude oil can be used in a few steps or all of the process.
For soybean oil, peanut oil, sesame oil and other oil material. If high quality of raw oil materials, oil machine high quality and reasonable of oil extraction process, the quality of crude oil is better, free fatty acid content is generally less than 2%, easy to refine, the refining equipment is not high wear.
