Detailed Explanation of Peanut Oil Screw Pressing Technology: Key Processes and Equipment Selection for Higher Oil Yield

In the realm of edible oil processing, traditional peanut oil pressing methods have long faced challenges such as low efficiency and high losses. The peanut oil screw pressing technology introduced by Penguin Group offers a revolutionary solution. This article delves into the core of this technology, exploring how it can significantly enhance oil yield and optimize production processes.

Working Principle and Process of Screw Pressing Technology

The screw pressing technology for peanut oil involves four key steps: cleaning, crushing, cooking, and pressing. The integrated design of the equipment streamlines these processes, reducing material losses and environmental pollution. For instance, traditional methods may result in a loss of up to 10% during the transfer between different processing steps, while the integrated screw press can cut this loss to less than 3%.

1. Cleaning

This step removes impurities such as dirt, stones, and broken peanuts from the raw materials. A well - cleaned raw material ensures a higher quality of the final oil product and also protects the subsequent processing equipment from damage.

2. Crushing

The cleaned peanuts are then crushed into smaller particles. This increases the surface area of the peanuts, making it easier for the oil to be released during the subsequent pressing process. The crushing process can typically break the peanuts into particles of about 2 - 3 mm in size.

3. Cooking

Cooking is a crucial step that affects the oil yield and quality. By heating the crushed peanuts to an appropriate temperature, the oil cells are broken down, facilitating oil extraction. The cooking temperature can be adjusted according to different requirements, usually ranging from 80°C to 120°C.

4. Pressing

Finally, the cooked peanuts are pressed by the screw press. The advanced screw design of the press applies continuous pressure to the peanuts, squeezing out the oil. Compared with traditional presses, the screw press can increase the oil yield by about 5 - 8 percentage points, reaching an average oil yield of up to 45%.

Comparison between Hot - pressing and Cold - pressing Processes

In peanut oil production, there are two main pressing processes: hot - pressing and cold - pressing. Each has its own characteristics and is suitable for different application scenarios.

Practical Operation and Industry Trends

In actual production, operators often encounter various problems. For example, the oil yield may decrease due to improper screw speed adjustment. Here are some practical operation tips:

In addition, with the increasing emphasis on environmental protection and energy conservation, the peanut oil processing industry is also moving towards green manufacturing. The screw press technology introduced by Penguin Group is in line with this trend, featuring energy - saving design and low - pollution operation.
