In the industrial production of sunflower oil, pressing and extraction are commonly used to extract oil. Pressing is a traditional oil-making process that relies on physical extrusion to make oil. The sunflower oil production process is green and healthy, and is favored by consumers; the sunflower oil extraction process fully contacts the oil through the solvent to extract the oil. Its advantage is that it can well control the residual oil in the cake and improve the oil yield. Sunflower seeds have a relatively high oil content, and the sunflower oil pressing process cannot solve the problem of residual oil in the cake well, which is a waste of oil for the sunflower oil mill. Therefore, in order to improve the oil yield of sunflower oil, the sunflower oil mill usually adopts the process of pre-pressing and then extracting to produce sunflower oil.
The pre-pressing and extraction process is to first press the sunflower seed raw material to extract oil, and then use the extraction method to extract the sunflower seed cake after pre-pressing, thereby reducing the residual oil rate in the sunflower seed cake, and can fully extract the oil in the sunflower seeds.
The extraction method of sunflower oil is to use chemical solvents to fully soak or spray sunflower seed cakes to obtain a mixed oil solution, and then recover the solvent through subsequent evaporation equipment, condensation equipment, etc. to obtain the desolventized crude sunflower seed oil. The extracted crude sunflower seed oil is refined by sunflower oil refining equipment to remove the solvent residual oil and excess impurities and harmful substances in the oil, which is an edible oil that meets the national standard requirements. The steps of sunflower oil refinery plant generally include dephosphorization, deacidification, dehydration, decolorization, deodorization, dewaxing and other processes.
The pre-pressing-extraction process requires a complete set of pressing equipment and extraction equipment. The quality of the process and equipment used in production directly affects the subsequent oil yield and oil quality. In order to obtain a better extraction effect and ensure the quality of oil, it is necessary to choose a powerful extraction equipment manufacturer and purchase high-quality oil equipment. Good edible oil extraction equipment and equipment manufacturers can provide considerable help for the subsequent development of the oil plant.
To purchase a sunflower oil pre-pressing and extraction production line, we recommend Henan Huatai Cereals and Oils Machinery Co., Ltd. The manufacturer has been committed to the research and development, production and sales of oil equipment for many years.
