In daily life, the demand for edible oil is constantly growing. Among various sources of edible oil, soybean oil is one of the most popular choices due to its rich nutrition and wide application. This is where soybean oil presses come into play, becoming an important tool in the oil - making industry.

The Oil - Extraction Process of Soybean Oil Presses

The oil - extraction process of soybean oil presses mainly includes several key stages. First is the cleaning stage. Soybeans need to be cleaned to remove impurities such as stones, sand, and dust. This step ensures the purity of the final oil product. Then comes the crushing stage. Cleaned soybeans are crushed into small particles, which helps to increase the contact area during subsequent processes and improve oil extraction efficiency. After that, the crushed soybeans go through a cooking process. By heating and moistening, the structure of the soybeans is further broken down, making the oil easier to separate. Finally, the cooked soybeans are sent to the pressing device, where physical pressure is applied to extract the oil.

Advantages of Different Types of Soybean Oil Presses

Small - Sized Soybean Oil Presses

Small - sized soybean oil presses are compact in size and easy to operate. They are suitable for small - scale home use or small workshops. With a processing capacity of about 50 - 100 kilograms of soybeans per day, they can meet the needs of a small family or a local community. Their advantage lies in their low investment cost and flexibility. You can place them in a small space and start the oil - making process quickly.

Integrated Soybean Oil Presses

Integrated soybean oil presses combine multiple functions such as cleaning, crushing, cooking, and pressing into one machine. This type of machine is highly automated, which can significantly reduce labor costs and improve production efficiency. It can process around 200 - 500 kilograms of soybeans per day, suitable for medium - sized enterprises. The integrated design also saves space and simplifies the operation process.

Large - Sized Soybean Oil Presses

Large - sized soybean oil presses are designed for large - scale industrial production. They have a high processing capacity, capable of handling 1000 - 5000 kilograms of soybeans per day. These machines are usually equipped with advanced technology and high - strength materials, ensuring stable operation and high oil extraction rate. They are ideal for large oil - processing factories.

Screw Soybean Oil Presses

Screw soybean oil presses use a screw mechanism to generate pressure for oil extraction. They have a high oil extraction efficiency, usually reaching 35% - 40%. This type of press is suitable for a variety of oil - bearing materials, not just soybeans. The screw design allows for continuous operation, which is very efficient for large - scale production.

Hydraulic Soybean Oil Presses

Hydraulic soybean oil presses use hydraulic pressure to extract oil. They are known for their gentle pressing process, which can produce high - quality oil with less damage to the oil molecules. The oil extraction rate of hydraulic presses is about 30% - 35%. They are often used for producing high - end edible oils or in situations where oil quality is of primary concern.

Real - World Case Studies

Many businesses have achieved excellent results by using soybean oil presses. For example, a small local workshop in a rural area started with a small - sized soybean oil press. By producing high - quality soybean oil, they quickly gained a good reputation in the local market. Within a year, they expanded their business and replaced the small press with an integrated one, increasing their daily production from 80 kilograms to 300 kilograms. Another large - scale oil - processing factory installed a large - sized screw soybean oil press. With its high processing capacity and stable performance, the factory's annual output of soybean oil increased by 50%.
