How the Advanced Screw Peanut Oil Machine Efficiently Produces High - Quality Peanut Oil

In daily life, peanut oil is a staple in many kitchens. Its rich flavor and high nutritional value make it a popular choice for cooking. Have you ever wondered how high - quality peanut oil is produced using an advanced screw peanut oil machine? Let's uncover the whole process together.

1. Shelling of Peanuts with Shells

The first step is to remove the shells from the peanuts. Specialized peanut shelling machines can efficiently separate the shells from the peanuts. This process not only improves the subsequent processing efficiency but also ensures the purity of the peanuts. For example, a modern shelling machine can handle about 500 - 800 kilograms of peanuts per hour, with a shelling rate of over 98%.

2. Peanut Cleaning and Pre - treatment

After shelling, the peanuts need to be cleaned. This step is crucial as it removes impurities such as sand, stones, and dust. Through a series of cleaning equipment, the cleanliness of peanuts can reach over 99%. Clean peanuts are the basis for producing high - quality peanut oil.

3. Cooking the Peanuts

Cooking is an important step that affects the flavor and quality of peanut oil. The temperature and time of cooking need to be precisely controlled. Generally, the cooking temperature is around 100 - 120 degrees Celsius, and the time is about 30 - 60 minutes. Appropriate cooking can make the peanuts release their fragrance and increase the oil yield.

4. Crushing the Peanuts

Crushing the cooked peanuts can further break down the cell structure of the peanuts, making it easier for the oil to be squeezed out. The crushed peanuts should have a suitable particle size, usually about 2 - 5 millimeters.

5. Hot - pressing and Cold - pressing Processes

There are two main processes for squeezing peanut oil: hot - pressing and cold - pressing. In the hot - pressing process, the peanuts are heated to a relatively high temperature before squeezing. This can increase the oil yield, with an average oil yield of about 45% - 50%. The hot - pressed peanut oil has a strong fragrance but may lose some nutrients due to high - temperature processing.

In contrast, the cold - pressing process squeezes the peanuts at a lower temperature (below 60 degrees Celsius). Although the oil yield is relatively lower, about 38% - 42%, the cold - pressed peanut oil retains more nutrients, such as vitamin E and unsaturated fatty acids.

6. Oil Extraction with the Advanced Screw Peanut Oil Machine

The advanced screw peanut oil machine plays a key role in this step. It uses a screw extrusion method to continuously squeeze the crushed peanuts, and the oil is gradually separated from the peanut residue. The machine has high efficiency and can ensure the continuous production of peanut oil.

7. Refining and Filling

The crude peanut oil obtained from squeezing needs to be refined. Refining includes processes such as degumming, deacidification, decolorization, and deodorization. Through these processes, the quality and stability of peanut oil can be improved. After refining, the peanut oil is filled into bottles, ready to be sent to the market.

It is worth mentioning that many peanut oil production enterprises pay attention to environmental protection and resource recycling. For example, the peanut residue after oil extraction can be used as feed or fertilizer, realizing the full utilization of resources.
