Shocking! The Secret of High - Efficiency Oil Extraction by Soybean Oil Press Machines Revealed

In daily life, edible oil is an essential part of our diet. Among various sources of edible oil, soybean oil is highly popular due to its rich nutrition and good taste. This is where soybean oil press machines come into play, playing a crucial role in the oil - extraction industry.

Let's first understand the oil - extraction process of soybean oil press machines. It generally consists of several key stages:

1. Cleaning

Before the oil - extraction process begins, soybeans need to be thoroughly cleaned. This step is to remove impurities such as dust, stones, and other foreign objects. Usually, cleaning equipment can remove more than 95% of impurities, ensuring the quality of the final oil product. For example, a well - designed cleaning system can process about 1 - 5 tons of soybeans per hour, depending on the scale of the machine.

2. Crushing

After cleaning, the soybeans are crushed into smaller particles. This increases the surface area of the soybeans, making it easier for the oil to be released during the subsequent processes. The crushing process can reduce the size of soybeans to about 2 - 5mm in diameter, improving the oil - extraction efficiency by approximately 10 - 15%.

3. Cooking

Cooking is a vital step in the oil - extraction process. By heating the crushed soybeans, the structure of the oil cells is broken, and the oil is more easily separated. The optimal cooking temperature is usually around 100 - 110°C, and the cooking time is about 20 - 30 minutes. This process can increase the oil - yield rate by about 5 - 8%.

4. Pressing

Finally, the cooked soybeans are sent to the pressing chamber. Through mechanical pressure, the oil is squeezed out from the soybeans. Modern soybean oil press machines can achieve an oil - yield rate of up to 18 - 22% from soybeans, which is quite efficient.

There are different types of soybean oil press machines, each with its own characteristics, advantages, and suitable scenarios:

1. Small - scale Soybean Oil Press Machines

These machines are suitable for small businesses or home use. They have a relatively small footprint and are easy to operate. For example, a small - scale machine can process about 50 - 200 kg of soybeans per day. Their advantage lies in their low cost and flexibility.

2. Integrated Soybean Oil Press Machines

Integrated machines combine multiple functions such as cleaning, crushing, cooking, and pressing into one unit. They are highly automated, reducing the need for manual labor. They can process 200 - 500 kg of soybeans per day, which is suitable for medium - sized oil - processing workshops.

3. Large - scale Soybean Oil Press Machines

Designed for large - scale oil - processing factories, these machines have a high processing capacity. They can process several tons to tens of tons of soybeans per day. Their advantage is high - efficiency mass production, which can meet the large - scale market demand.

4. Screw Oil Press Machines

Screw oil press machines use a screw mechanism to apply pressure. They have a high oil - yield rate and are suitable for various oil - bearing materials. They can achieve a continuous oil - extraction process, with an efficiency of processing about 1 - 10 tons of soybeans per day.

5. Hydraulic Oil Press Machines

Hydraulic oil press machines use hydraulic pressure to extract oil. They are known for their gentle pressing process, which can produce high - quality oil. They are more suitable for small - batch and high - quality oil production, with a processing capacity of about 50 - 300 kg of soybeans per day.

Let's look at some real - life cases. A small - scale food processing factory in a rural area purchased a small - scale soybean oil press machine. After using it for a few months, they found that the oil - yield rate increased by about 10% compared to the previous manual method, and the quality of the oil also improved significantly. Another medium - sized oil - processing workshop installed an integrated soybean oil press machine. The automation of the machine reduced labor costs by about 30% and increased the daily production capacity by 20%.

In conclusion, soybean oil press machines are a high - efficiency choice for oil extraction. Whether you are a small - business owner, a home user, or a large - scale factory, there is a suitable model for you.
