There are two common processing technologies for corn oil: oil pressing and extraction. In the corn oil production process, the selection of appropriate equipment and technology has an important impact on the quality and output of corn oil. Therefore, the purchase of corn oil production machine and technology needs to be considered comprehensively from many aspects, including oil characteristics, output, finished oil quality requirements and investment budget.
There are large and small corn oil production machine manufacturers. The output of small edible oil machine manufacturers is limited. It is suitable to adopt a corn oil pressing process with flexible equipment configuration to produce pressed corn oil that meets the health needs of consumers. The corn oil pressing machine has many specifications, flexible configuration, and can be put into production quickly.
Large-scale corn oil processing projects are more suitable for extraction oil production technology, because the corn oil pressing process has a high amount of residual oil, which affects the oil yield of the finished product, while the corn oil extraction process can fully extract corn oil through solvent to extract oil. The residual oil in the cake after extracting can be controlled below 1%, which improves the oil yield and cake quality. The corn oil extraction machine has large output, high efficiency, and high degree of automation, which can reduce manual operation errors and improve production efficiency and product quality.
Corn oil extracted by extracting and pressing processes is not finished oil. To obtain high-quality corn oil, it needs to be processed through corn oil refining process such as degumming, deacidification, decolorization, deodorization, and dewaxing. After removing substances that affect the quality of corn germ oil and are harmful to the human body, the finished corn oil that meets the edible oil quality standards is obtained.
When choosing corn oil production machine and technology, if the customer does not have a full understanding of the oil equipment, it is recommended to make consultation and cooperation from the cooking oil equipment manufacturer. The manufacturer can provide detailed plans and technical support to help the corn oil mill choose corn oil processing machine and technology that meet the needs.
