In this special report, we will take you on a journey to explore the intricate and professional process of producing high - quality peanut oil. Let's start by setting a little mystery to pique your curiosity.
The first step in the peanut oil production is shelling the peanuts. On average, a modern peanut shelling machine can process about 500 kilograms of shelled peanuts per hour. This initial process separates the peanuts from their shells, getting them ready for the subsequent steps.
The hot pressing process starts with heating the peanuts. The peanuts are usually heated to a temperature of around 120 - 130 degrees Celsius. This heating step helps to break down the cell structure of the peanuts, making it easier to extract the oil. After heating, the peanuts are sent to the press. The hot - pressed oil has a rich flavor and high yield. On average, the oil yield of hot pressing can reach about 45 - 50%. The oil cake produced from hot pressing is often used in animal feed production, which is a good source of protein for livestock.
In contrast, the cold pressing process is carried out at a lower temperature, usually below 60 degrees Celsius. This gentle process helps to preserve more nutrients in the oil, such as vitamins and antioxidants. However, the oil yield of cold pressing is relatively lower, about 35 - 40%. The oil cake from cold pressing can be used to produce peanut protein powder, which is widely used in the food and beverage industry.
| Process Type | Temperature | Oil Yield | Oil Cake Usage |
|---|---|---|---|
| Hot Pressing | 120 - 130°C | 45 - 50% | Animal Feed |
| Cold Pressing | Below 60°C | 35 - 40% | Peanut Protein Powder |
Peanut cleaning machines play a crucial role in the production process. These machines can remove impurities such as dust, stones, and broken peanuts. A high - efficiency peanut cleaning machine can clean about 80 - 90% of the impurities in peanuts, ensuring the quality of the final oil product.
Baking temperature has a significant impact on the quality and flavor of peanut oil. When the baking temperature is between 140 - 150 degrees Celsius, the peanuts will develop a more intense nutty flavor, which is transferred to the oil. However, if the temperature is too high, it may cause the peanuts to burn, affecting the quality of the oil.
The crushing step is essential for increasing the oil yield. By crushing the peanuts into smaller particles, the surface area for oil extraction is increased. Studies have shown that proper crushing can increase the oil yield by about 5 - 8%.
We understand you may have some questions about the peanut oil production process. Here are some frequently asked questions:
Q: Which type of peanut oil is healthier, hot - pressed or cold - pressed? A: Cold - pressed peanut oil retains more nutrients due to the lower processing temperature, so it is often considered a healthier option for those who focus on nutrition.
Q: Can the oil cake be used for human consumption? A: The oil cake from cold pressing can be processed into peanut protein powder for human consumption, while the hot - pressed oil cake is mainly used for animal feed.
