In today's dynamic market, your small-scale oil mill is likely facing the challenge of diversifying raw materials. Rotating the production of multiple oil crops has become a necessity, but it also brings a series of pain points. How can you efficiently process various oil crops in rotation? This article will provide you with in-depth insights and practical tips.

1. Understanding the Characteristics of Common Oil Crops

Let's first take a look at the physical characteristics and oil content of common oil crops such as soybeans, peanuts, rapeseeds, sunflower seeds, and sesame. Here is a data comparison table:

2. Key Parameters in the Pretreatment Process

2.1 Moisture Control

Moisture content is crucial in the pretreatment of oil crops. For example, soybeans should have a moisture content of about 10 - 12% before pressing. If the moisture is too high, it may lead to poor oil extraction efficiency and affect the quality of the oil. On the other hand, if the moisture is too low, the oil yield may also decrease. Here is a general moisture control standard for different oil crops:

• Soybeans: 10 - 12%
• Peanuts: 6 - 8%
• Rapeseeds: 7 - 9%
• Sunflower Seeds: 8 - 10%
• Sesame: 5 - 7%

2.2 Crushing Granularity

The crushing granularity of oil crops also affects the oil extraction process. For instance, rapeseeds should be crushed to a certain fineness to ensure better oil release. Generally, the appropriate crushing granularity for different oil crops is as follows:

• Soybeans: Medium - fine
• Peanuts: Coarse - medium
• Rapeseeds: Fine
• Sunflower Seeds: Medium
• Sesame: Fine

2.3 Feeding Speed

The feeding speed needs to be adjusted according to the type of oil crop and the performance of the screw press. For high - oil - content crops like sesame, a slower feeding speed is usually required to ensure thorough oil extraction. A general rule of thumb is to start with a relatively slow speed and then adjust it based on the actual situation.

3. Parameter Adjustment for Screw Oil Presses

Each oil crop requires specific parameter settings for the screw oil press. Here is a practical guide for parameter adjustment:

1. Soybeans: Adjust the pressure and temperature of the press according to the moisture and granularity. Usually, a moderate pressure and temperature are suitable.
2. Peanuts: Due to their high oil content, a higher pressure may be needed, but also pay attention to preventing over - pressing.
3. Rapeseeds: Fine - tune the screw speed and pressure to ensure efficient oil extraction.
4. Sunflower Seeds: Adjust the clearance between the screw and the barrel to optimize the oil extraction process.
5. Sesame: Use a slow - speed and high - pressure setting to fully extract the oil.

4. Real - World Case Studies

Let's look at a real - world case from a small - scale oil mill. At first, they faced many problems when rotating the production of different oil crops, such as low oil yield and frequent equipment failures. However, by following the above - mentioned tips and making continuous adjustments, they finally achieved stable and high - yield production throughout the year. This case shows the flexibility and potential of the screw cold - press in multi - variety rotation production.
