With the advancement of science and technology, commercial soybean oil press has become an important equipment in the oil processing industry. Spiral soybean oil extraction machine, with its high efficiency, energy saving and easy operation. It is widely used in the production process of soybean oil. This machine mainly uses mechanical pressing technology to continuously press the oil with a rotating spiral shaft, so as to efficiently extract oil. BTM oil press manufacturer provides peanut oil press, sesame oil press, rapeseed oil press and other raw material oil pressing equipment. Contact us for more details.
Can Soybean Oil Be Cold Pressed?
Soybean oil can be extracted by cold pressing process. Cold pressing process refers to pressing oil at a temperature below 60℃. Cold pressing process can reduce the damage to the nutrients in the oil, and obtain high-quality soybean oil and bean cake. 2.However, the oil yield of cold pressing is lower than that of hot pressing. Although the quality of hot pressed soybean oil is lower than that of cold pressing, its oil yield is high. Hot pressing is to roast soybeans and then press oil. The oil yield of hot pressing is 3-5% higher than that of cold pressing.
Working Principle Of Soybean Oil Press
Screw oil press is a key equipment for extracting soybean oil. Its working principle is to use the mechanical pressure generated by the screw to effectively separate oil from oil. In the oil pressing process, it needs to pre-treat first, including cleaning to remove impurities. Then, soybeans are fed into the oil press through the feed port. In the pressing chamber, as the screw shaft rotates, the soybeans continue to move forward and are subjected to high pressure treatment. So that the oil is precipitated from the soybeans and flows out through the circular and strip slits. In addition, the unique design of the oil press further improves the oil extraction efficiency under high pressure through the friction between the embryos and the interaction between the embryos and the screw and the pressing chamber.
What Is The Oil Extraction Rate Of Soybeans?
Soybean is a high-quality high-protein oil crop. The oil content is 15%-26%. The oil extraction rate is affected by soybean varieties, planting areas, climate and soil conditions, etc. Generally speaking, the oil extraction rate of soybeans is 15%-20%. That is, 150-200kg of soybean oil can be extracted from one ton of soybeans.
Performance Characteristics Of Soybean Oil Extraction Machine
1. Significant oil yield. As one of the key indicators for evaluating the performance of oil presses, high oil yield represents the efficient use of raw materials and brings significant economic benefits to manufacturers. With its unique screw pressing technology, the “soybean oil extraction machine” achieves efficient oil extraction. It ensures a high oil yield, and maximizes the value of each soybean.
2. Simple operation. The soybean oil press adopts intelligent control function, which is simple to operate and easy to maintain. This greatly reducing the labor intensity of users and improving production efficiency.
3. Stable structure and durability. During the long-term high temperature and high pressure operation, the solid material and reasonable structural design ensure the stable operation of the oil press, reduce the failure rate, and extend the service life of the equipment.
4. Energy saving and environmental protection. The soybean oil press complies with the national environmental protection policy and adopts an energy-saving design. It only reduces energy consumption, but also reduces the operating costs of the enterprise.
Production Process Of Soybean Oil Pressing
- The first is the soybean preparation stage. This stage requires the soybeans to be thoroughly cleaned to remove impurities. The purpose of washing soybeans is to improve the efficiency of oil extraction and reduce unnecessary wear on equipment. Washed soybeans can enter the next processing step.
- During the feeding stage, the operator introduces the prepared soybeans into the oil press via the feed port of the soybean oil extraction machine. It is crucial to ensure that the soybeans are fed uniformly to achieve optimal pressing results.
- The pressing stage is the most critical part of the entire production process. In this stage, the soybeans are continuously pushed and subjected to high pressure by the spiral shaft within the pressing chamber.
- As a result, the oil is extracted and flows out through the oil discharge port of the press.
- The subsequent stage is oil filtration, where a filtration system removes impurities from the oil to ensure its quality. The filtered oil can either meet sales standards or undergo further refinement.
- Finally, the last stage involves discharging the bean cake. The pressed bean cake, which serves as a valuable animal feed, can be resold or repurposed, contributing to effective resource recycling.
Soybean Oil Pressing Production Line
BTM not only supplies single oil pressing equipment for small oil pressing workshops. But also supplies complete oil processing equipment for large oil pressing plants. The complete soybean oil pressing process includes: soybean → cleaning → baking → pressing → filtering → crude oil → refining workshop.
1. Soybean cleaning: Clean the soybean raw materials, remove impurities and surface dirt. And it ensures the hygiene and quality of raw materials.
2. Baking: Use the soybean baking machine to bake the washed soybeans to destroy the enzymes and proteins in the soybeans. It is convenient for subsequent pressing and oil extraction.
3. Pressing: The baked soybeans go into the screw press for pressing, and the soybean oil and remaining soybean cake are squeezed out.
4. Sedimentation and separation: The liquid resulting from the pressing is centrifuged and precipitated to separate the oil and water, thereby obtaining pure soybean oil.
5. Refining: Deodorize, deacidify, decolorize and other treatments of soybean oil to remove odors and impurities, making it purer and more transparent.
1.6. Packaging: Fill, seal and package the refined soybean oil to ensure quality and hygiene.
