We take pride in our 100% turnkey engineering ability, which enables us to provide complete solutions for oil mill plants from pretreatment, pressing, leaching, refining to packing.
Our oil mill machinery is designed to press oil crops such as rapeseed, sunflower seeds, cottonseed and soybean to obtain high-quality edible oil. We use scientific management and innovative manufacturing ideas to ensure that our products meet the highest standards of quality. As a result, we have become the leading oil machinery production and export base in China.
Oil mill plant process:
Oilseed Pretreatment:
Pretreatment of material is an important process in oil processing. The purpose of pretreatment is to improve the appearance of oil plants to make the pressing and leaching process more rapid and efficient. It includes the following series of process: drying, color sorting, crushing, softening, peeling, extrusion, flaking, steaming and frying, pressing, etc.
Our pretreatment technology and equipment is suitable for processing various oil plants, and unique design and manufacturing can be realized according to the actual situation, different oil plants and requirements of our clients to improve oil quality and ensure the smooth operation of subsequent sections. Adopt the most advanced automatic control system and the central computer control system. Network technology is applied for remote monitoring and maintenance of principal machines to achieve electromechanical integration and automation, and make the whole oil mill plant energy conservation and environmental protection.
Scope of application:
The pretreatment of soybean, rapeseed, cottonseed, sunflower seeds, peanut, corn germ, rice bran, safflower seed, tea seed, sesame seed, palm, walnut and other oil plants.
Main equipment:
Lifting scraper, dust catcher, sizing screen, soften tower, crusher, air separator, flaking mill, bulking machine, steaming and frying pan, etc.
Oil Press
At present, oil mill plant is widely used in continuous mechanical oil extraction with the pressing capacity of 1 – 1000 TPD. Prepressing (combination with solvent extraction) and full pressing (purely mechanical oil extraction process) are the two main pressing methods used in oil mill plant for oil extraction. Prepressing and full pressing have their own features and advantages when pressing oil plants.
Prepressing- Oil Mill Plant
In prepressing technology, oil plants are pressed lightly without the application of full pressure. The residual oil content in the prepressed cake is about 13%-17%. Then, the pre-pressed cake would be sent to the solvent extraction plant. We provide pre-pressing machines manufactured in accordance with global standards for oil mill plant with advantages of easy operation, convenient maintenance and cost-effective.
Full Pressing- Oil Mill Plant
The full or single pressing technology is used in oil mill plants of small and medium capacity. In full pressing process, oil plants are pressed in single step under the principle of mechanical extraction to separate oil from seeds. As a result, maximum oil yield can be obtained from high oil content plants. The residue oil in the pressed cake is only about 4-6%. Full pressing technology can be used for processing different oil plants. The full pressing oil mill plant produced by our company has superior quality and higher yield.
Generally speaking, the oil yield of mechanical pressing is only 65-70%. Thus, prepressing of oil plants is often used to extract 60 to 70% of the oil, while the residual oil is extracted by solvent.
Solvent Extraction
Generally, for oil plants with high oil content, such as rapeseed, sunflower seed and peanut kernels, prepressing – solvent extraction process is often used for oil extraction. For oil plants with low oil content like soybean and rice bran, they can be processed with direct solvent extraction process.
Oil Refinery
Oil refining mainly refers to the purification of unrefined oil. Impurities in the unrefined oil would not only affect the edible value and oil storage, but bring difficulty for further processing. Therefore, the purpose of the oil refining is to remove the undesired and harmful impurities from oil according to different requirements and uses to get refined oil products that can meet the quality standard. The oil can be refined by chemical or physical refining process according to the types and qualities of the oil to be processed. The process of oil refining includes degumming, neutralization, bleaching, deodorization and winterization. Chemical Refining is the most widely used process for vegetable oils, especially seed oils like soybean oil, canola oil, corn oil, cottonseed oil, sunflower oil, safflower oil, etc.
Over the years, we have built more than 200 oil mill plants both domestically and internationally. In addition, we have sold over 6000 units of small oil press equipment. Our oil mill machinery has been well received both domestically and internationally, with exports to over 30 countries and regions including Russia, India, South Africa, Ukraine, Nepal and Indonesia.
At our company, we are committed to providing our clients with the highest quality oil mill machinery and services. We are proud of our reputation for excellence in the oil engineering industry and look forward to continuing to provide our clients with innovative solutions for their oil mill plant needs.
