Cottonseed oil processing is one of the main applications of cottonseed. In the food industry, cottonseed oil is an important edible oil with high nutritional value and wide market demand. Cottonseed cake after oil extraction can be used to produce food additives and feed, further increasing the benefits of the cottonseed oil mill. To process cottonseed oil, two oil production processes, pressing and extraction, are commonly used in industry.
For large-scale cottonseed oil processing projects, the extraction process has great advantages in production. The extraction process is to fully soak the oil with organic matter to extract the oil. Not only can it increase the oil yield, but the cottonseed meal after extraction also has a relatively high protein content, which is the main raw material for making animal feed. The cottonseed oil extraction process has a series of advantages in production, such as high oil yield, high efficiency, high degree of automation, low production cost, and good cake quality.
In actual production, cottonseeds are cleaned, delinted, shelled, separated from shells and kernels, steamed and fried before extraction. The cottonseed oil pretreatment process can reduce the content of impurities in the oil, control the temperature and moisture of the oil, make it more conducive to extracting oil, and improve the oil yield and oil quality. The pretreated cottonseeds are sent to the extractor to extract cottonseed oil.
The wet meal after cottonseed extraction is directly dephenolized by dephenolization solvent in the multi-stage dephenolization extraction equipment. After dephenolization, it is mechanically desolventized and low-temperature dried to obtain the dephenolized cottonseed protein product. The extracted cottonseed mixed oil is filtered and then enters graded evaporation and stripping to obtain crude cottonseed oil, which is sent to the workshop for refining. The solvent for extracting cottonseed oil and cottonphenol can be reused after passing through the comprehensive recovery system.
The crude cottonseed oil obtained by extraction is then processed by multiple processes of cottonseed oil refining machine to remove impurities in the oil and harmful substances such as cottonphenol that affect human health. The quality is improved, meets the quality standards of edible oil, and can be eaten with confidence.
As one of the main processing technologies in the oil and fat industry, the extraction process is widely used in edible oil processing. More than 80% of domestic oil and fat are processed by this process. For oil mills, it can not only fully extract oil and fat, but also obtain high-quality by-products to increase the profits of oil mills. However, the extraction equipment has a high degree of automation and high equipment investment costs, which is not suitable for small and medium-sized edible oil processing plants. The production process and equipment quality of each manufacturer are different. In the process of equipment selection, oil mills should also pay attention to the quality of equipment and the technical strength, production capacity and after-sales service capabilities of the manufacturer. Choose reliable manufacturers from many manufacturers to cooperate and lay a solid foundation for subsequent production.
